Abstract
An embodiment of the invention discloses an antistatic microphone, which comprises a circuit board, a pickup hole, an audio processing chip and a microphone housing, wherein the pickup hole is arranged in the circuit board, and the audio processing chip and the microphone housing are fixedly arranged on the circuit board. The antistatic microphone also comprises a first metal foil covering on the hole wall of the pickup hole, and the first metal foil is connected with a second metal foil for grounding in the circuit board, thereby preventing static from entering the antistatic microphone through the pickup hole, which may cause damage to the audio processing chip, reducing failure of the microphone due to static, and prolonging the service life of the antistatic microphone.
Description
Technical field
The present embodiments relate to microphone, more particularly, to a kind of antistatic microphone.
Background technology
The microphone installed on the mobile apparatus mainly includes the descending microphone of plate and the up microphone of plate.Normal conditions
Under, the pickup hole of the descending microphone of plate is arranged on the printed circuit board (PCB) below microphone casing body, and printed circuit is run through in pickup hole
Plate.Because the pickup hole on printed circuit board (PCB) is unearthed, therefore extraneous static can enter inside microphone from pickup hole, damages
The internal process chip of bad microphone, shortens the service life of microphone.
Content of the invention
The invention provides a kind of antistatic microphone, can enter inside microphone from pickup hole to solve extraneous static,
Damage the process chip within microphone, shorten the problem of the service life of microphone.
A kind of first aspect, there is provided antistatic microphone, including：Circuit board, the pickup being opened on described circuit board
Hole and be fixed on the audio processing chip on described circuit board and microphone case；
Described antistatic microphone also includes covering the first metal forming on the hole wall of described pickup hole, described first metal
Paper tinsel is connected for the second metal forming of ground connection with described circuit board, prevents electrostatic from entering by described pickup hole described anti-quiet
Electric microphone damages described audio processing chip.
So, in the embodiment of the present invention, pickup hole hole wall lays the first metal forming, and by the first metal forming with electricity
The second metal forming for ground connection in the plate of road connects, and enters antistatic Mike such that it is able to effectively prevent electrostatic from passing through pickup hole
Windage loss bad audio processing chip, effectively reduces and lost efficacy because of the microphone that electrostatic causes, extend the use longevity of antistatic microphone
Life.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of specification, and in order to allow the above and other objects of the present invention, feature and advantage can
Become apparent, below especially exemplified by the specific embodiment of the present invention.
Brief description
In order to be illustrated more clearly that the technical scheme of the embodiment of the present invention, below by institute in the description to the embodiment of the present invention
Need use accompanying drawing be briefly described it should be apparent that, drawings in the following description be only the present invention some enforcement
Example, for those of ordinary skill in the art, without having to pay creative labor, can also be according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is the structural representation of the antistatic microphone of one embodiment of the invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment a part of embodiment that is the present invention, rather than whole embodiments.Based on this
Embodiment in bright, the every other enforcement that those of ordinary skill in the art are obtained under the premise of not making creative work
Example, broadly falls into the scope of protection of the invention.
Embodiment one
Fig. 1 is the structural representation of the antistatic microphone of one embodiment of the invention.Antistatic microphone shown in Fig. 1
Including：
Circuit board 1, pickup hole 2, audio processing chip 3 and microphone case 4, pickup hole 2 opens up on the circuit card 1, sound
Frequency process chip 3 and microphone case 4 are separately fixed on circuit board 1, and microphone case 4 is set in audio processing chip 3
Outside.
Wherein, circuit board 1 can be PCB (Printed Circuit Board, printed circuit board), audio processing chip 3
It can be MEMS (Microelectromechanical Systems, MEMS) chip.
In addition to above-mentioned part, the antistatic microphone described in the embodiment of the present invention also includes covering on the hole wall of pickup hole 2
The first metal forming 5, the first metal forming 5 with circuit board 1 for ground connection the second metal forming (not shown) be connected.Based on
The connection of one metal forming 5 and the second metal forming so that pickup hole 2 is grounded, when extraneous static reaches near pickup hole 2, electrostatic
Can be discharged according to the path on first metal forming 5- the second metal forming-ground, antistatic microphone will not be entered by pickup hole 2
Inside, will not cause damage to audio processing chip 3.Therefore, the antistatic microphone described in the embodiment of the present invention can be effective
Prevent electrostatic from passing through the audio processing chip 3 within pickup hole 2 entrance antistatic microphone damage, effectively reduce and cause because of electrostatic
Microphone lost efficacy, extend the service life of antistatic microphone.
First metal forming 5 has sucking action to the electrostatic near pickup hole 2, in order to improve the first metal forming 5 to electrostatic
Attraction, the anti-static ability improving microphone it is preferable that the laying area of the first metal forming 5 can be increased, specifically, the
One metal forming 5 can also cover at circuit board 1 is positioned at the upper wall and lower wall of pickup hole 2 port.
Antistatic microphone can have different structure, and correspondingly, audio processing chip 3 there may be different structure.Preferably
Ground, the audio processing chip positioned at antistatic microphone within includes 3 inner-cavity structures with cavity, the cavity of inner-cavity structure and
Pickup hole 2 is oppositely arranged, and the end face of the inner-cavity structure of audio processing chip 3 is fixing on the circuit card 1.
The setting of inner-cavity structure, so that audio processing chip 3 and pickup hole 2 have certain clearance space, extends quiet
Electricity reaches the time of audio processing chip 3.When pickup hole 2 nearby has electrostatic, electrostatic is near pickup hole 2 or in inner chamber knot
Will be absorbed by the first metal forming 5 inside structure, without reaching on audio processing chip 3, the inner chamber of therefore audio processing chip 3
The setting of structure can improve the antistatic performance of microphone further.Preferably, the inner-cavity structure of audio processing chip 3 is U
Type structure.
