Embodiment Construction

[0015] In order to more clearly describe the specific implementation of the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Such as figure 1 As shown, the microphone dust-proof structure of the present invention includes: a microphone body 1, a circuit board 5, the microphone body 1 is located in the microphone sound inlet channel 4 and fixed on the circuit board 5, the microphone body 1 is provided with an inlet The sound hole 2 is provided with a dustproof device 3 at the sound inlet 2. The dustproof device 3 used in the present invention is a dustproof net or a dustproof cover. No matter which kind of dustproof device is used, it must cover the sound inlet 2 of the microphone body 1 when installed. When a dust-proof net is used, the dust-proof net is arranged on the shell of the microphone body 1 at the sound inlet 2.

Abstract

The invention relates to a microphone dustproof structure, comprising a microphone body and a circuit board. The microphone body is arranged in a microphone sound inlet channel, is fixed on the circuit board, and is provided with a sound inlet and a dustproof device covering the sound inlet. After the microphone dustproof structure disclosed by the invention is adhered on the surface in an assembling process, the dustproof screen is immediately adhered on the sound inlet of the microphone body, thus the risk of pollution by dust impurity can be avoided in the processes of assembling a machine and conveying the machine, the damage on a vibration film due to the dust in a communication terminal machine can be avoided, and the protection on the microphone is more direct and complete; simultaneously, the microphone dustproof structure has a dustproof function when being used by a user, the risk of microphone disability is reduced to the maximum extent, and the communication quality and the microphone reliability are improved.

Description

Technical field [0001] The invention relates to a microphone on a call terminal device, in particular to a dustproof structure of the microphone. Background technique [0002] From the perspective of the principle of the microphone, the reason why the microphone can pick up sound is that a diaphragm induces the airflow of the outside world to generate vibration. This vibration causes the capacitance between the microphone diaphragm and the other plate to change, thereby obtaining an electric wave signal. Sound and electricity conversion. When the vibration of the diaphragm is abnormal, the acoustic-electric conversion is abnormal, which will affect the quality of the call. Therefore, ensuring the normal vibration of the diaphragm is the key to the normal operation of the microphone. [0003] From the production and assembly of the microphone to consumer use, the environment in which the microphone is located will affect the diaphragm, especially dust and impurities in the environ...
