CN203423786U - Earphone with front damping baffle plate - Google Patents

The utility model discloses an earphone with a front damping baffle plate, which comprises a front shell, a rear shell, a sound film, a guide tube and the front damping baffle plate, wherein the front shell is provided with a front cavity, the rear shell is connected with the front shell in a matched mode and provided with a rear cavity, the sound film is arranged in a sound cavity formed by the front cavity and the rear cavity, the guide tube is arranged in the front cavity and can conduct sound, and the front damping baffle plate is fixed in the front shell, arranged opposite to the sound film and used for guide the sound. As the earphone is internally provided with the front damping baffle plate, the sound produced by the sound film is sent out to the ear through the front damping baffle plate by taking physical conditions such as the size, the distance, the shape and the like as a guide, thereby enabling output of the sound to have stereoscopic impression and a sense of space, and greatly improving a sound output effect of the earphone.

Damping baffle earphone before a kind of band

Technical field

The utility model belongs to earphone technical field, relates to the front damping baffle earphone of a kind of band.

Background technology

Earphone is personal stereo, and its selection is personal question naturally, and anyone experience all can not push away and be and wide.The purposes of earphone, time and the place of using earphone, oneself taste, the tonequality of earphone is all will consider while selecting secondary applicable oneself a earphone.Nowadays for earphone, more and more require sectionalization, according to different occasions, select suitable earphone to become a kind of symbol of trend life.

Along with improving constantly of people's living standard, people are also more and more higher to the requirement of the effect of earphone, but the effect of existing earphone is conventionally very single, awaits further raising.

Summary of the invention

The problem that the utility model exists for prior art proposes the front damping baffle earphone of a kind of band, and object is to improve earphone voice output effect.

The utility model is achieved in that

Damping baffle earphone before a kind of band, comprise the fore shell with ante-chamber, be connected with described fore shell and there is the back cover of back cavity, be arranged on described ante-chamber and back cavity and form the tibial membrane in sound chamber, the conduit that is arranged in described ante-chamber and can admittance sound, is fixed in described fore shell and and the front damping baffle for the sound that leads that is oppositely arranged of described tibial membrane.

Damping baffle earphone before above-mentioned a kind of band, wherein, the profile of described conduit is and suitable cylindric of described ante-chamber, described conduit and described fore shell tight fit.

Damping baffle earphone before above-mentioned a kind of band, wherein, described front damping baffle comprises that described screening line and described connecting portion are connected as a single entity for the screening line of the sound that leads with for described screening line is fastened on to the connecting portion in described fore shell.

Damping baffle earphone before above-mentioned a kind of band, wherein, described connecting portion is strip, described conduit has the sound channel of admittance sound, in described sound channel, be provided with link, on described link, there is and the suitable connecting hole of described connecting portion described connecting portion and described connecting hole interference fit.

Damping baffle earphone before above-mentioned a kind of band, wherein, described connecting portion is cylindrical, described connecting hole is cylindrical hole.

Damping baffle earphone before above-mentioned a kind of band, wherein, described screening line is in the form of annular discs, and described connecting portion is in the center of described screening line.

Damping baffle earphone before above-mentioned a kind of band, wherein, described screening line is towards the end face of the tibial membrane formation concave surface that caves inward, and the convex surface of described concave surface and tibial membrane is corresponding.

Damping baffle earphone before above-mentioned a kind of band, wherein, has uniform gap in described screening line and between the opposing end face of concave surface and the inwall of described fore shell.

Damping baffle earphone before above-mentioned a kind of band, wherein, described link has four legs, and described four legs are divided into four passages by sound channel.

Damping baffle earphone before above-mentioned a kind of band, wherein, described link has three legs, and described three legs are divided into three passages by sound channel.

Damping baffle earphone before a kind of band provided by the utility model, due to damping baffle before being provided with in earphone, the sound that tibial membrane can be sent sends people ear according to physical conditions such as the large small distance shapes of baffle for leading by sound by front damping baffle, make the output of sound there is third dimension and spatial impression, greatly improve earphone voice output effect.

Embodiment

Below just accompanying drawing in conjunction with the embodiments, is described in further detail embodiment of the present utility model, so that technical solutions of the utility model are easier to understand, grasp.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

For example, when described front damping baffle 300 is connected on described fore shell 100, can arrange netted for being fixed on the fixed part on fore shell 100 by hiding line 310 hiding line 310 peripheries.

The shape of described screening line 310 can be to wait polygon, be preferably discoid, described screening line 310 caves inward and forms concave surface 311 towards the end face of tibial membrane 400, described concave surface 311 is corresponding with the convex surface of tibial membrane 400, namely the each point on concave surface 311 equates to the distance of corresponding point on tibial membrane 400, between described like this concave surface 311 and tibial membrane 400, just form a uniform gap, be beneficial to the sound external world of leading regularly, avoid random scattering, to guarantee quality and the effect of voice output.In like manner, in described screening line 310 and between the opposing end face of concave surface 311 and the inwall of described fore shell 100, there is uniform gap, so that sound is unobstructed and output equably.The sound that tibial membrane 400 sends, by hiding after line 310 guiding, forms a third dimension and the extremely strong effect of spatial impression, has greatly improved the audibility of earphone.

Should be understood that; the foregoing is only preferred embodiment of the present utility model; be not sufficient to limit the technical solution of the utility model; for those of ordinary skills; within spirit of the present utility model and principle; can be increased and decreased according to the above description, replaced, converted or be improved, and all these increases and decreases, replace, conversion or improve after technical scheme, all should belong to the protection range of the utility model claims.
