Abstract
The utility model provides a sound generating device which comprises a basin rack and a damping membrane. The basin rack is provided with a leakage hole covered by the damping membrane. The sound generating device further comprises a damping cover connected with the basin rack, the damping membrane is pressed on one side face of the basin rack with the leakage hole by the damping cover in a leaning manner, a through hole is arranged on the damping cover, and the through hole and the leakage hole are at least partially overlapped. As the damping effect of the sound generating device is good, the product consistency can be ensured.
Description
[technical field]
The utility model relates to a kind of microphone device, relates in particular to a kind of microphone device of novel damping structure.
[background technology]
Microphone device is widely used in portable electronic equipments such as mobile phone, notebook computer, hearing aids.Along with fast development, the people of these portable electronic equipments are more and more stronger to its functional requirement, the also corresponding development apace of the mini-sound device that is applied thereon.
Wherein, influence an effect that important factor is damping of microphone device performance, as everybody knows, make various frictions and other inhibitions of free vibration decay, we are referred to as damping.Damping should be made good use of and Frequency Response can be improved.
The microphone device of dependency structure, as shown in Figure 1, it comprises basin frame 1, basin frame 1 periphery is provided with the annular damping membrane 2 of a circle.The microphone device of this damping structure, its damping membrane 2 is bad with the applying consistency of basin frame 1, influences properties of product and rate of finished products.
Therefore the real microphone device that is necessary to provide a kind of novel damping structure.
[utility model content]
The technical problem that the utility model need solve provides the good microphone device of a kind of damping.
For solving the problems of the technologies described above, the utility model provides a kind of microphone device, comprise basin frame and damping membrane, described basin has set up leak, described damping membrane covers described leak, this microphone device comprises also and is connected with the basin frame and damping membrane is pressed on the damping lid that basin sets up a side that is equipped with leak that this damping covers and is provided with through hole, and described through hole and leak are overlapped at least.
Preferably, described damping membrane periphery is provided with becket, and described becket is embedded in the damping lid.
Preferably, the material of described damping membrane is sponge, adjustable sound paper or yarn thin,tough silk.
The beneficial effects of the utility model are: use the damping structure that adds one deck damping lid on damping membrane, make that the applying of damping membrane and basin frame is effective, damping is even, and consistency of product can guarantee that rate of finished products gets a promotion simultaneously.
[description of drawings]
Fig. 1 is the utility model microphone device prior art profile;
Fig. 2 is the utility model microphone device one embodiment profile.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 2, be the utility model microphone device one embodiment stereogram, involving vibrations system (not shown), magnetic circuit system (not shown) and accommodate vibrational system and the basin frame 1 of magnetic circuit system ', damping membrane 2 ' and with basin frame 1 ' be connected and with damping membrane 2 ' press on basin frame 1 ' damping lid 3 ', described basin frame 1 ' be provided with first leak 11 about the microphone device central point ' and second leak 12 ', described damping lid 3 ' be provided with first through hole 31 about the microphone device central point ' and second through hole 32 ', described first leak 11 ' with first through hole 31 ' overlap at least, described second leak 12 ' with second through hole 32 ' overlap at least, described damping membrane 2 ' periphery be provided with becket 4 ', described becket 4 ' be embedded at damping lid 3 ' in, described damping lid 3 ' be provided with basin frame 1 ' a have side of leak.
The basic application of microphone device is that the signal of telecommunication is converted into voice signal, the generation of sound relies on the vibrating function of vibrational system, in this vibration processes, will exert an influence to the microphone device body, for eliminating this influence, at the microphone device outer surface damping being set is good selection.During this use is novel, described damping membrane 2 ' material be sponge, adjustable sound paper or yarn thin,tough silk etc.; The number of leak is not limited to two; The number of through hole is not limited to two, and leak and through hole are overlapped at least.
Microphone device of the present utility model, use damping membrane 2 ' above add one deck damping lid 3 ' damping structure, make damping membrane 2 ' with basin frame 1 ' applying effective, damping is even, the while consistency of product can guarantee that rate of finished products gets a promotion.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
