Abstract

A sound pickup device comprises a sound disc that is of column shape and comprises a first wall and a second wall; wherein, the first wall and the second wall are two bottoms of the column respectively and are provided with a plurality of small holes on the axial direction. The small holes passing through the first wall and the second wall are used for the sound to pass through the sound disc. And a layer of diaphragm is positioned on the first wall and the second wall respectively.

Description

Pick-up

Technical field

The utility model relates to a kind of pick-up, relates in particular to a kind of uniform pick-up of various microphone Air permenbility capacitances that is used for.

Background technology

Pick-up is the necessary accessory of the microphone of various occasions, sees also Fig. 1, and present pick-up comprises that one columniformly advances that sound dish 2, is columniform to go out sound dish 3.This advances sound dish 2 and goes out sound dish 3 all to comprise an appearance wall 4 and an inner surface wall 5, this appearance wall 4 and inner surface wall 5 are respectively cylindrical two bottom surfaces, this advances sound dish 2 and goes out sound dish 3 and all offers several apertures 6 along axial direction, and these apertures 6 run through this appearance wall 4 and inner surface wall 5.This inner surface wall 5 that advances inner surface wall 5 of sound dish 2 and go out sound dish 3 sticks together, and these apertures 6 alignment of advancing sound dish 2 and going out sound dish 3 are advanced this sound dish 2 and gone out sound dish 3 interlocking tightly and be in the same place with bolt then.This appearance wall 4 that advances sound dish 2 all posts one deck vibrating membrane 7 with the appearance wall 4 that goes out sound dish 3.Sound advances sound dish 2 from this and enters microphone, spreads out of from going out sound dish 3 then.

The structure of above-mentioned pick-up is advanced the sound dish and to go out sound dish required thickness identical, if their thickness is inequality, one thicker, and one thin, and a bit then Air permenbility and capacitance are inhomogeneous, and sensitivity is inconsistent.Advance the sound dish and went out the sound dish before assembling, need polish their appearance wall, can not polish simultaneously because advance the sound dish and go out the sound dish, can only successively polish, be easy to cause one thick, one thin, cause Air permenbility, capacitance inhomogeneous, sensitivity is inconsistent, and both flatnesses are variant.

Summary of the invention

The purpose of this utility model is to provide a kind of uniform pick-up of various microphone Air permenbility capacitances that is used for.

For achieving the above object, the utility model provides a kind of pick-up, and this pick-up comprises a sound dish, and this sound dish comprises a first wall, one second wall, respectively offers several apertures on this first wall and second wall, and these apertures run through this first wall and second wall.

It is one cylindrical that this sound dish is.

This first wall and second wall are respectively cylindrical two bottom surfaces.

Several apertures on this first wall and second wall are all offered along axial direction.

The one side that this first wall enters as sound, the one side that second wall then spreads out of for sound.

The one side that this second wall enters as sound, the one side that first wall then spreads out of for sound.

Respectively be provided with one deck vibrating membrane on this first wall and second wall.

The utlity model has following beneficial effect: in the utility model, only need a sound dish is installed, not only have effect and the function of advancing the sound dish and going out the sound dish of the prior art concurrently; And in the polishing course of processing, can polish simultaneously this first wall and second wall, can guarantee the flatness indifference of the first wall and second wall, the more important thing is and to avoid advancing in the prior art sound dish and go out inconsistent Air permenbility that causes of sound dish thickness and the inconsistent problem of the inhomogeneous sensitivity of capacitance.

Description of drawings

Fig. 1 is the stereogram of the pick-up of prior art.

Fig. 2 is the stereogram of the utility model pick-up.

Embodiment

See also Fig. 2, a kind of pick-up, it comprises a sound dish 1, it is one cylindrical that this sound dish 1 is.

This sound dish 1 comprises a first wall 12, one second wall 14.This first wall 12 and second wall 14 are respectively cylindrical two bottom surfaces.Each offers several apertures 16 along axial direction on this first wall 12 and second wall 14.

These apertures 16 run through this first wall 12 and second wall 14, are used for for sound by sound dish 1.

Respectively be provided with one deck vibrating membrane 18 on this first wall 12 and second wall 14.

Above-mentioned first wall 12 can be used as the one side that sound enters, the one side that 14 on second wall spreads out of for sound, and outside sound enters microphone from this first wall 12, spreads out of from second wall 14 then.

Same, above-mentioned second wall 14 can be used as the one side that sound enters, the one side that 12 of first walls spread out of for sound, and sound enters microphone from this second wall 14, spreads out of from first wall 12 then.

In the utility model, only need a sound dish 1 is installed, not only have effect and the function of advancing the sound dish and going out the sound dish of the prior art concurrently; And in the polishing course of processing, can polish simultaneously this first wall 12 and second wall 14, can guarantee the flatness indifference of the first wall 12 and second wall 14, the more important thing is and to avoid advancing in the prior art sound dish and go out inconsistent Air permenbility that causes of sound dish thickness and the inconsistent problem of the inhomogeneous sensitivity of capacitance.
