At the same time, energy saving and emission reduction has also become a hot topic in improving environmental issues. As a source of public environmental pollution, noise affects people's work and life, and is one of the four major pollutions in the world. The traditional way to control noise pollution is to set up isolation or protection on its transmission path. Although the harm of noise to human beings has been weakened to a certain extent, this part of energy cannot be effectively used. The emergence of noise power generation has great significance to the improvement of the environment and energy saving and emission reduction, but the current noise power generation has a low utilization rate of sound wave energy. How to improve the utilization rate of noise energy has become a key issue in noise power generation.

具体实施方式detailed description

下面结合附图对本发明的具体实施方式做详细说明。The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

一种基于人耳骨链式传导的噪音发电装置，如图1~图2、图9~图10所示，包括：声波接收单元1、振动膜2、仿人耳听骨链杠杆单元3、声电转换单元4、稳压放大电路。A noise power generation device based on human ear bone chain conduction, as shown in Figures 1 to 2 and Figures 9 to 10, comprising: a sound wave receiving unit 1, a vibrating membrane 2, a human ear bone chain lever unit 3, Acoustic-to-electric conversion unit 4, voltage stabilizing amplifier circuit.

声波接收单元1收集来自自由场中任何方向声波，声波接收单元1的输出端连接仿人耳听骨链杠杆单元3的一端，声波接收单元的输出端1与仿人耳听骨链杠杆单元3的一端之间设置有振动膜2，仿人耳听骨链杠杆单元3的另一端连接声电转换单元4，声电转换单元4的输出端连接稳压放大电路的输入端，稳压放大电路的输出端连接至蓄电池，连接如图3所示。The sound wave receiving unit 1 collects sound waves from any direction in the free field. The output end of the sound wave receiving unit 1 is connected to one end of the human ear ossicle chain lever unit 3, and the output end 1 of the sound wave receiving unit is connected to the human ear ossicle chain lever unit 3. A vibrating membrane 2 is arranged between one end of the human ear, and the other end of the human ear ossicle chain lever unit 3 is connected to the acoustic-electric conversion unit 4, and the output end of the acoustic-electric conversion unit 4 is connected to the input end of the voltage-stabilizing amplifier circuit, and the voltage-stabilizing amplifier circuit The output end of the battery is connected to the battery, and the connection is shown in Figure 3.

所述的基于人耳骨链式传导的噪音发电装置，还包括声波收集单元11，与麦克风的集音罩类似，采用双曲抛物面集音罩，充分收集来自自由场中任何方向的声波，多个声波接收单元1均匀布置在声波收集单元11内。声波收集单元11的设计外形成双抛物面状不仅增大了接触声波的面积，而且与声波传播方向垂直，使声波收集量达到最大化，同时也对内部各单元起到保护作用。The described noise power generation device based on human ear bone chain conduction also includes a sound wave collecting unit 11, which is similar to the sound collecting cover of a microphone and adopts a hyperbolic parabolic sound collecting cover to fully collect sound waves from any direction in a free field. The sound wave receiving units 1 are evenly arranged in the sound wave collecting unit 11 . The sound wave collecting unit 11 is designed to form a double paraboloid shape, which not only increases the area exposed to sound waves, but also is perpendicular to the direction of sound wave propagation, maximizing the amount of sound wave collection, and at the same time protects the internal units.

如图4所示，声波接收单元1采用雷达状双层空腔结构，尽可能多地吸收声波收集单元11收集的声波，声波接收单元1包括共振腔5和盲性管道6；共振腔5表面均匀分布有多个聚声用的小孔7，一部分声波通过聚声用的小孔7进入共振腔5内，汇集后进入中间扩音用的大孔8内；另一部分声波直接进入中间扩音用的大孔8内，进入共振腔5内的声波在盲性管道6内产生共振后传输至振动膜2，起到最大程度的放大声压效能的作用。As shown in Figure 4, the sound wave receiving unit 1 adopts a radar-like double-layer cavity structure to absorb the sound waves collected by the sound wave collecting unit 11 as much as possible. The sound wave receiving unit 1 includes a resonant cavity 5 and a blind pipeline 6; A plurality of small holes 7 for sound gathering are evenly distributed, and part of the sound waves enter the resonant cavity 5 through the small holes 7 for sound gathering, and then enter the large hole 8 for sound reinforcement in the middle after gathering; the other part of the sound waves directly enters the sound reinforcement in the middle In the large hole 8 used, the sound waves entering the resonant cavity 5 are resonated in the blind pipe 6 and then transmitted to the vibrating membrane 2 to maximize the effect of amplifying the sound pressure performance.

鼓膜、听骨链及其转轴模式如图5所示，鼓膜12与镫骨底板14的面积之比为18.6，听骨链13的长短臂的长度比为1.3，听骨链13的长短臂的长度比1.3将到达听骨链13的声波放大1.3倍，而鼓膜12与镫骨底板14的面积之比18.6又将声波放大18.6倍，如图6所示，鼓膜12的面积大大超过镫骨底板14的面积，故作用于镫骨底板14单位面积上的压力大大超过作用于鼓膜12上的压力，通过图6的增压效应补偿了声波的能量衰减。The pattern of the tympanic membrane, ossicular chain and their axis of rotation is shown in Figure 5. The ratio of the area of the tympanic membrane 12 to the stapes floor 14 is 18.6, the length ratio of the long and short arms of the ossicular chain 13 is 1.3, and the length of the long and short arms of the ossicular chain 13 The length ratio of 1.3 amplifies the sound wave reaching the ossicular chain 13 by 1.3 times, and the ratio of the area of the tympanic membrane 12 to the stapes base plate 14 is 18.6 amplifies the sound wave by 18.6 times. As shown in Figure 6, the area of the tympanic membrane 12 is much larger than the stapes base plate 14, so the pressure acting on the unit area of the stapes floor 14 greatly exceeds the pressure acting on the tympanic membrane 12, and the energy attenuation of the sound wave is compensated by the supercharging effect in FIG. 6 .

本实施方式采用仿生学原理设计仿人耳听骨链杠杆单元3，如图7所示，仿人耳听骨链杠杆单元3的长臂9与短臂10的比值为1.3。振动膜2的功能仿鼓膜12，声电转换单元4的功能仿镫骨底板14， 仿人耳听骨链杠杆单元3通过其一端连接的振动膜2的有效振动面积与另一端接触声电转换单元的面积的比值将声波的振动放大。In this embodiment, the bionics principle is adopted to design the human ear ossicle chain lever unit 3, as shown in FIG. 7, the ratio of the long arm 9 to the short arm 10 of the human ear ossicle chain lever unit 3 is 1.3. The function of the vibrating membrane 2 imitates the tympanic membrane 12, the function of the acoustic-electric conversion unit 4 imitates the stapes floor 14, and the lever unit 3 imitates the effective vibration area of the vibrating membrane 2 connected at one end to the acoustic-electric conversion unit at the other end. The ratio of the areas of the cells amplifies the vibration of the sound wave.

声电转换单元4采用PVDF压电薄膜，若干压电薄膜球面采用悬臂梁式的支撑方式布置成具有一定曲率的球面阵列，尽可能的使来自不同方向的声波垂直作用在压电薄膜上，提高声电转换效率；在图12中，（a）为悬臂梁式的支撑方式，（b）为周边固定的支撑方式，（c）为自由边界的支撑方式，（d）为简支支撑方式，悬臂梁式的支撑方式，较其他三种支撑方式可产生最大的挠度，同时具有较低的谐振频率，可使声电转换效率达到最高。由于声波在自由场中呈球形传播，在实际传播中传播方向也接近于球形， 所以在组装这些单元时组装成具有一定曲率的球面阵列， 以尽可能的使来自不同方向的声音垂直入射进声电转换单元4，如图8所示，其中（a）为球面阵列的正视图，（b）为球面阵列的横剖图。Acoustoelectric conversion unit 4 adopts PVDF piezoelectric film, and several piezoelectric film spherical surfaces are arranged in a spherical array with a certain curvature using a cantilever beam support method, so that sound waves from different directions act vertically on the piezoelectric film as much as possible, improving Acoustic-to-electric conversion efficiency; in Figure 12, (a) is the cantilever beam support method, (b) is the peripheral fixed support method, (c) is the free boundary support method, (d) is the simple support method, The cantilever beam support method can produce the largest deflection compared with the other three support methods, and at the same time has a lower resonance frequency, which can achieve the highest sound-to-electricity conversion efficiency. Since the sound wave propagates in a spherical shape in a free field, the propagation direction is also close to a sphere in the actual propagation. Therefore, when assembling these units, they are assembled into a spherical array with a certain curvature, so as to make the sound from different directions incident on the sound as much as possible. The electrical conversion unit 4 is shown in FIG. 8 , wherein (a) is a front view of the spherical array, and (b) is a cross-sectional view of the spherical array.

本实施方式的稳压放大电路如图11所示，选用MAX1672作为稳压芯片，具有升压式或降压式DC/DC变换器的功能。该芯片的输出电压是一个恒定的值。MAX1672外围器件主要包括一个肖特基二极管，一个10uH的电感，两个较大的钽电容(100uF)，输出端接一个4.7uF的电容及若干电阻。两个100uF的钽电容一个接在输入端，主要起到去处输入纹波的作用。由于压电薄膜电路的输出电阻较大，对于加大的开关负载将产生较大的输出纹波，4.7uF的电容就是起到缓解负载剧烈变化，减小输出波动的作用。另一个100uF的钽电容的输出电阻较小，可以有效地提高输出电流。The voltage stabilizing amplifier circuit of this embodiment is shown in FIG. 11 , and MAX1672 is selected as the voltage stabilizing chip, which has the function of a step-up or step-down DC/DC converter. The output voltage of the chip is a constant value. The peripheral components of MAX1672 mainly include a Schottky diode, a 10uH inductor, two larger tantalum capacitors (100uF), and a 4.7uF capacitor and several resistors connected to the output terminal. One of the two 100uF tantalum capacitors is connected to the input terminal, which mainly plays the role of eliminating input ripple. Due to the large output resistance of the piezoelectric film circuit, a large output ripple will be generated for the increased switching load. The 4.7uF capacitor is to relieve the drastic change of the load and reduce the output fluctuation. Another 100uF tantalum capacitor has a smaller output resistance and can effectively increase the output current.
