背景技术Background technique

现有的蓝牙耳机在使用过程中，主耳机与终端设备之间通过建立蓝牙连接传输信号，主耳机与从耳机之间也需通过建立蓝牙连接传输信号。由于现有的蓝牙耳机采用单一的天线结构，而天线的传输是具有指向性的。因此只能用折中的方式使天线兼顾两个方向的传输，导致蓝牙耳机不能在主耳机与终端设备以及主耳机与从耳机之间的信号传输中达到最优状态，进而导致蓝牙耳机出现声音卡顿、延迟等现象。During the use of the existing Bluetooth earphones, a Bluetooth connection is established between the master earphone and the terminal device to transmit signals, and the master earphone and the slave earphones also need to establish a Bluetooth connection to transmit signals.

为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说明。In order to illustrate the technical solutions described in this application, the following will be described in detail in conjunction with specific drawings and embodiments.

现有的蓝牙耳机在使用过程中，主耳机与终端设备之间通过建立蓝牙连接传输信号，主耳机与从耳机之间也需通过建立蓝牙连接传输信号。主耳机与从耳机在进行信号传输时，主耳机与从耳机的信号通常需要围绕用户头部进行衍射传播，使该信号受到衰减，此时非常考验耳机天线在水平方向的性能；主耳机与终端设备在进行信号传输时，信号需要绕过用户身体进行传播，也会使该信号受到衰减，此时非常考验耳机天线在垂直方向的性能。由于现有的蓝牙耳机采用单一的天线结构，而天线的传输是具有指向性的。因此只能用折中的方式使天线兼顾两个方向的传输，导致蓝牙耳机不能在主耳机与终端设备以及主耳机与从耳机之间的信号传输中达到最优状态，进而导致蓝牙耳机出现声音卡顿、延迟等现象。During the use of the existing Bluetooth earphones, a Bluetooth connection is established between the master earphone and the terminal device to transmit signals, and the master earphone and the slave earphones also need to establish a Bluetooth connection to transmit signals. When the master earphone and the slave earphones are transmitting signals, the signals of the master earphone and the slave earphones usually need to propagate around the user's head through diffraction, so that the signal is attenuated. At this time, the performance of the earphone antenna in the horizontal direction is a test; When the device is transmitting signals, the signal needs to bypass the user's body for propagation, which will also attenuate the signal. At this time, the performance of the earphone antenna in the vertical direction is very critical. Since the existing bluetooth headset adopts a single antenna structure, the transmission of the antenna is directional. Therefore, only a compromise method can be used to make the antenna take into account the transmission in both directions, resulting in the Bluetooth headset not being able to reach the optimal state in the signal transmission between the master headset and the terminal device, as well as between the master headset and the slave headset, which in turn causes the Bluetooth headset to appear sound. Caton, delay and other phenomena.

The Bluetooth headset in this application may include a master headset and a slave headset, and the master headset and the slave headset are respectively provided with a horizontally polarized antenna and a vertically polarized antenna. Among them, the horizontally polarized antenna refers to the antenna installed in the earphone close to the horizontal direction in the wearing state, which has better transmission and receiving performance for signals transmitted in the horizontal direction; the vertically polarized antenna refers to the antenna in the wearing state, The antenna installed in the earphone in a nearly vertical direction has better transmission and reception performance for signals transmitted in the vertical direction.

Wherein, the terminal adds a header to the first radio frequency signal each time before sending the first radio frequency signal, and the first test signal of the header of the first radio frequency signal is used to assist the main earphone and determine which antenna to select for the slave earphone to receive the first radio frequency.

The first signal-to-noise ratio corresponding to the first test signal of the packet header, and the first bit error rate corresponding to the first test signal of the packet header of the first radio frequency signal obtained by the second horizontally polarized antenna and the second vertically polarized antenna.

示例性地，当用户只使用TWS耳机中的一个耳机时，此时该耳机为主耳机。终端设备将待发送的音频信号转换为第一射频信号后进行广播，该主耳机在检测到第一射频信号时，基于该主耳机中的第一水平极化天线获取第一射频信号包头的第一测试信号对应的接收信号强度指示，以及基于该主耳机中的第一垂直极化天线获取第一射频信号包头的第一测试信号对应的接收信号强度指示。Exemplarily, when the user only uses one of the TWS earphones, the earphone is the main earphone at this time. The terminal device converts the audio signal to be sent into a first radio frequency signal and then broadcasts it. When the main earphone detects the first radio frequency signal, it obtains the first radio frequency signal packet header based on the first horizontally polarized antenna in the main earphone.

The same processing manner may be used to obtain the first received signal strength indication corresponding to the first test signal of the first radio frequency signal packet header by the first vertically polarized antenna. Obtaining the first received signal strength indication corresponding to the first test signal of the first radio frequency signal header from the second horizontally polarized antenna and the second vertically polarized antenna from the earphone is similar to this, and will not be repeated here.

当用户同时使用TWS耳机中的两个耳机时，直接与终端进行蓝牙连接的为主耳机，与主耳机之间建立虚拟蓝牙连接，间接与终端设备进行连接的为从耳机。具体地，终端设备将待发送的音频信号转换为第一射频信号后进行广播，该主耳机在检测到该第一射频信号的同时向从耳机传达终端设备广播第一射频信号的信息，使从耳机可监听到终端设备广播的该第一射频信号。主耳机在检测到终端设备广播的第一射频信号后，获取第一水平极化天线及第一垂直极化天线对第一射频信号包头的第一测试信号对应的第一接收信号强度指示。从耳机在监听到终端设备发送的第一射频信号后，获取第二水平极化天线及第二垂直极化天线对第一射频信号包头的第一测试信号对应的第一接收信号强度指示。When the user uses two earphones in the TWS earphone at the same time, the master earphone that directly connects to the terminal with Bluetooth establishes a virtual Bluetooth connection with the master earphone, and the slave earphone that indirectly connects with the terminal device. Specifically, the terminal device converts the audio signal to be sent into a first radio frequency signal and then broadcasts it. When the master earphone detects the first radio frequency signal, it conveys the information that the terminal device broadcasts the first radio frequency signal to the slave earphone, so that the slave earphone The earphone can monitor the first radio frequency signal broadcast by the terminal device. After detecting the first radio frequency signal broadcast by the terminal device, the main earphone acquires a first received signal strength indication corresponding to the first test signal of the first radio frequency signal header by the first horizontally polarized antenna and the first vertically polarized antenna.

When the user uses two earphones in the TWS earphone at the same time, after the master earphone and the slave earphone both receive the first radio frequency signal sent by the terminal device, The master headphone will send a sync signal to the slave headphone. Before sending the synchronization signal, the master earphone adds a header to the synchronization signal. At this time, the second test signal of the header of the synchronization signal is used to assist the slave earphone in judging which antenna to select to receive the second radio frequency signal.

When the slave earphone detects the synchronization signal sent by the master earphone, it acquires the received signal strength indication corresponding to the second test signal at the packet header of the synchronization signal. Optionally, in a practicable manner, the signal-to-noise ratio corresponding to the second test signal of the synchronization signal packet header by the second horizontally polarized antenna and the second vertically polarized antenna can also be obtained from the earphone, and the second The horizontally polarized antenna and the second vertically polarized antenna correspond to the bit error rate of the second test signal at the header of the synchronization signal.

When the user uses two earphones in the TWS earphone at the same time, the terminal device converts the audio signal to be sent into the first radio frequency signal and broadcasts it. After detecting the first radio frequency signal, the earphone receives the first radio frequency signal based on the first target antenna of the main ear. The master earphone forwards the received first radio frequency signal to the slave earphone. Specifically, the master earphone may divide the first radio frequency signal into multiple second radio frequency signals, and forward them to the slave earphones in batches. When the second radio frequency signal sent by the main earphone is detected from the earphone, the second received signal strength indication corresponding to the second test signal of the second radio frequency signal header by the second horizontally polarized antenna and the second vertically polarized antenna is obtained, based on the respective The corresponding second received signal strength indicator determines an antenna for receiving the second radio frequency signal, and receives the second radio frequency signal based on the determined antenna. At the same time, the master earphone also adjusts the antenna to forward the remaining second radio frequency signal to the antenna of the same type as the slave earphone. For example, if the slave earphone receives the second radio frequency signal based on the second horizontally polarized antenna, then the master earphone performs signal transmission with the slave earphone based on the first horizontally polarized antenna; if the slave earphone receives the second radio frequency signal based on the second vertically polarized antenna, then The master earphone performs signal transmission with the slave earphone based on the first vertically polarized antenna. Exemplarily, when the slave earphone receives the second radio frequency signal for the first time, it can send a feedback signal to the master earphone, and the master earphone obtains the received signal strength indication corresponding to the feedback signal, and determines which antenna to use to continue to transmit the signal based on the received signal strength indication. The second radio frequency signal is forwarded from the headset. The positions of the master earphone and the slave earphone are opposite, therefore, the antennas used for signal transmission between the master earphone and the slave earphone are antennas in the same direction. Optionally, in a practicable manner, the signal-to-noise ratio corresponding to the second test signal of the forwarded signal packet header by the second horizontally polarized antenna and the second vertically polarized antenna can also be obtained from the earphone, and the second The horizontally polarized antenna and the second vertically polarized antenna correspond to the bit error rate of the second test signal of the header of the forwarded signal.

Step S209 will be specifically described below.

S209：所述主耳机通过所述主耳第一目标天线向所述终端设备发送响应信号。S209: The main earphone sends a response signal to the terminal device through the first target antenna of the main ear.

当主耳机与从耳机之间的第二射频信号传输完成后，主耳机需要向终端设备发送响应信号，该响应信号用于提示终端设备可以发送新一轮的射频信号。主耳机通过主耳第一目标天线向终端设备发送响应信号。After the transmission of the second radio frequency signal between the master earphone and the slave earphone is completed, the master earphone needs to send a response signal to the terminal device, and the response signal is used to prompt the terminal device to send a new round of radio frequency signals. The main earphone sends a response signal to the terminal device through the first target antenna of the main ear.

主耳机检测其与从耳机进行信号传输所采用的天线，与主耳机和终端设备之间进行信号传输所采用的天线是否相同，即主耳机检测其与从耳机进行第二射频信号传输时采用的天线，与主耳机和终端设备进行第一射频信号传输时采用的天线是否为同一个天线，若为同一个天线，则主耳机基于主耳第一目标天线发送响应信号。The master earphone detects whether the antenna used for signal transmission with the slave earphone is the same as the antenna used for signal transmission between the master earphone and the terminal device, that is, the master earphone detects whether the antenna used for the second RF signal transmission with the slave earphone Antenna, whether the antenna used by the main earphone and the terminal device to transmit the first radio frequency signal is the same antenna, if it is the same antenna, the main earphone sends a response signal based on the first target antenna of the main ear.

例如，主耳机与终端设备进行第一射频信号传输时采用的第一垂直极化天线，主耳机与从耳机进行第二射频信号传输时采用的是第一垂直极化天线，此时，主耳机基于第一垂直极化天线发送响应信号至终端设备。关于第一水平极化天线与第一垂直极化天线类似，此处不再赘述。For example, the first vertically polarized antenna is used when the master earphone and the terminal device transmit the first radio frequency signal, and the first vertically polarized antenna is used when the master earphone and the slave earphone transmit the second radio frequency signal. At this time, the master earphone The response signal is sent to the terminal device based on the first vertically polarized antenna. The first horizontally polarized antenna is similar to the first vertically polarized antenna, and will not be repeated here.

若检测到主耳机与终端设备进行信号传输时采用的天线，和主耳机与从耳机进行信号传输时采用的天线不同，则主耳机通过与终端设备进行信号传输时采用的天线向终端设备发送响应信号。即若检测到主耳机与从耳机进行信号传输所采用的天线，与主耳机和终端设备之间进行信号传输所采用的天线不相同，则将主耳机当前的天线切换为其与终端设备进行信号传输时所采用的天线，并基于切换后的天线向终端设备发送响应信号。If it is detected that the antenna used for signal transmission between the master earphone and the terminal device is different from the antenna used for signal transmission between the master earphone and the slave earphone, the master earphone will send a response to the terminal device through the antenna used for signal transmission with the terminal device Signal. That is, if it is detected that the antenna used for signal transmission between the master earphone and the slave earphone is different from the antenna used for signal transmission between the master earphone and the terminal device, then the current antenna of the master earphone is switched to be used for signal transmission with the terminal device. The antenna used for transmission, and based on the switched antenna, a response signal is sent to the terminal device.

例如，主耳机与终端设备进行第一射频信号传输时采用的第一垂直极化天线，主耳机与从耳机进行第二射频信号传输时采用的是第一水平极化天线，此时，主耳机将第一水平极化天线切换至第一垂直极化天线，基于第一垂直极化天线发送响应信号至终端设备。也可理解为，当主耳机与终端设备进行第一射频信号传输时采用的天线，与主耳机与从耳机进行第二射频信号传输时采用的天线不同时，选择主耳机与终端设备进行第一射频信号传输时采用的天线发送响应信号至终端设备。For example, the first vertically polarized antenna is used when the master earphone and the terminal device transmit the first radio frequency signal, and the first horizontally polarized antenna is used when the master earphone and the slave earphone transmit the second radio frequency signal. At this time, the master earphone The first horizontally polarized antenna is switched to the first vertically polarized antenna, and a response signal is sent to the terminal device based on the first vertically polarized antenna. It can also be understood that when the antenna used for the first radio frequency signal transmission between the master earphone and the terminal device is different from the antenna used for the second radio frequency signal transmission between the master earphone and the slave earphone, select the master earphone and the terminal device for the first radio frequency signal transmission. The antenna used for signal transmission sends a response signal to the terminal device.

When the user wears two earphones in the TWS earphone at the same time, the master earphone that directly connects with the mobile phone through Bluetooth, establishes a virtual Bluetooth connection with the master earphone, and the slave earphone that indirectly connects with the mobile phone. The mobile phone converts the audio signal to be sent into the first radio frequency signal and then broadcasts it. In the first communication time slot, the master earphone detects the first radio frequency signal, and at the same time conveys the information of the terminal device broadcasting the first radio frequency signal to the slave earphone, so that The first radio frequency signal broadcast by the mobile phone can be monitored from the earphone. After the main earphone detects the first radio frequency signal broadcast by the mobile phone in the first communication time slot, based on the first horizontally polarized antenna in the main earphone, the received signal strength indication corresponding to the first test signal of the first radio frequency signal header is obtained, and The received signal strength indication corresponding to the first test signal of the first radio frequency signal packet header is obtained based on the first vertically polarized antenna in the main earphone. After the earphone monitors the first radio frequency signal sent by the terminal device in the second communication time slot, based on the second horizontally polarized antenna in the earphone, the received signal strength indication corresponding to the first test signal of the header of the first radio frequency signal is acquired , and the received signal strength indication corresponding to the first test signal of the packet header of the first radio frequency signal obtained based on the second vertically polarized antenna in the earphone. The master earphone and the slave earphone respectively determine their corresponding target antennas according to the acquired received signal strength indication. For example, when the user puts the mobile phone in his pocket, the main earphone and the slave earphone are vertical to the mobile phone. At this time, the vertically polarized antennas of the master earphone and the slave earphone have better performance for RF signal transmission. According to the received signal strength indicators corresponding to the two antennas, it can be obtained that the one with the better received signal strength indicator is the first vertically polarized antenna, and the first vertically polarized antenna is used as the first target antenna of the main ear, and based on the first vertically polarized The antenna receives the first radio frequency signal sent by the mobile phone; the earphone is also the same process.

若出现用户佩戴一只耳机(如主耳机)，另一只从耳机与手机均放在桌子上，此时主耳机通过比较两个天线对应的接收信号强度指示，可得到接收信号强度指示较优的一方为第一垂直极化天线，并基于该第一垂直极化天线接收手机发送的第一射频信号。而从耳机与手机处于水平的状态，此时从耳机通过比较两个天线对应的接收信号强度指示，可得到接收信号强度指示较优的一方为第二水平极化天线，并基于该第二水平极化天线接收手机发送的信号。If the user wears an earphone (such as the main earphone), and the other earphone and the mobile phone are placed on the table, the main earphone can obtain the better received signal strength indicator by comparing the received signal strength indicators corresponding to the two antennas. One side is the first vertically polarized antenna, and receives the first radio frequency signal sent by the mobile phone based on the first vertically polarized antenna. While the slave earphone and the mobile phone are in a horizontal state, at this time, the slave earphone compares the received signal strength indicators corresponding to the two antennas, and it can be obtained that the one with the better received signal strength indicator is the second horizontally polarized antenna, and based on the second level The polarized antenna receives the signal sent by the mobile phone.

主耳机与从耳机都接收到射频信号后，主耳机会向从耳机发送第二射频信号(以同步信号为例)。在第二通讯时隙从耳机检测到主耳机发送的同步信号，获取该同步信号对应的接收信号强度指示，并基于该接收信号强度指示确定用于传输同步信号的天线。比如，用户将主耳机与从耳机都佩戴在耳朵上，此时主耳机与从耳机处于平行状态，从耳机与主耳机通过比较各自对应的接收信号强度指示，可得到接收信号强度指示较优的一方为水平极化天线。主耳机与从耳机基于水平极化天线传输同步信号。或者，用户佩戴一只耳机(如主耳机)，另一只从耳机放在桌子上，此时主耳机与从耳机呈垂直状态，从耳机与主耳机通过比较各自对应的接收信号强度指示，可得到接收信号强度指示较优的一方为垂直极化天线。主耳机与从耳机基于垂直极化天线传输同步信号。After both the master earphone and the slave earphone receive the radio frequency signal, the master earphone will send a second radio frequency signal (taking a synchronization signal as an example) to the slave earphone. In the second communication time slot, the earphone detects the synchronization signal sent by the main earphone, obtains the received signal strength indicator corresponding to the synchronization signal, and determines the antenna for transmitting the synchronization signal based on the received signal strength indicator. For example, the user wears both the master earphone and the slave earphone on the ear. At this time, the master earphone and the slave earphone are in a parallel state. By comparing the received signal strength indicators corresponding to the slave earphone and the master earphone, the receiver with a better received signal strength indicator can be obtained. One side is a horizontally polarized antenna. The master earphone and the slave earphone transmit synchronization signals based on horizontally polarized antennas. Alternatively, the user wears one earphone (such as the master earphone), and the other slave earphone is placed on the table. At this time, the master earphone and the slave earphone are in a vertical state. The one with the better received signal strength indication is the vertically polarized antenna. The master earphone and the slave earphone transmit synchronization signals based on vertically polarized antennas.

当主耳机与从耳机之间的同步信号传输完毕后，在第三通讯时隙主耳机向手机发送响应信号。若在这一轮的射频信号传输中，开始主耳机基于第一垂直极化天线接收手机广播的射频信号，中途还是通过第一垂直极化天线与从耳机进行同步信号的传输，则此时直接基于当前使用的天线即第一垂直极化天线向手机发送响应信号。若在这一轮的射频信号传输中，开始主耳机基于第一垂直极化天线接收手机广播的射频信号，中途通过第一水平极化天线与从耳机进行同步信号的传输，则此时将天线切换为第一垂直极化天线，通过第一垂直极化天线向手机发送响应信号。手机接收到主耳机发送的响应信号，进行新一轮的射频信号传输。After the synchronization signal transmission between the master earphone and the slave earphone is completed, the master earphone sends a response signal to the mobile phone in the third communication time slot. If in this round of radio frequency signal transmission, the master earphone starts to receive the radio frequency signal broadcast by the mobile phone based on the first vertically polarized antenna, and transmits the synchronization signal with the slave earphone through the first vertically polarized antenna in the middle, then directly A response signal is sent to the mobile phone based on the currently used antenna, ie, the first vertically polarized antenna. If in this round of radio frequency signal transmission, the main earphone starts to receive the radio frequency signal broadcast by the mobile phone based on the first vertically polarized antenna, and transmits the synchronization signal with the slave earphone through the first horizontally polarized antenna in the middle, then at this time the antenna Switch to the first vertically polarized antenna, and send a response signal to the mobile phone through the first vertically polarized antenna. The mobile phone receives the response signal sent by the main earphone, and performs a new round of radio frequency signal transmission.

From another perspective, in a possible implementation mode, the master earphone detects that it performs signal transmission with it. When the object changes, the antenna it chooses to transmit the signal also changes accordingly. Then ensure that the appropriate antenna is selected for signal transmission, so that the signal transmission between the master earphone and the terminal device as well as the master earphone and the slave earphone can reach the optimal state, avoiding the phenomenon of sound stuttering and delay in the Bluetooth earphone.
