Micropore waterproof front chamber and electret capacitive microphone assembling apparatus

Abstract

The invention discloses a micropore waterproof front chamber and electret capacitive microphone assembling apparatus. The apparatus comprises an ABS housing, a dustproof cloth, waterproof epoxy glue, a waterproof airtight chamber and a glue sleeve, wherein the ABS housing is arranged at the periphery of the apparatus, the intermediate position of the upper end of the ABS housing is provided with a sound receiving hole, the ABS housing is internally provided with the dustproof cloth, a microphone, the waterproof airtight chamber and the glue sleeve, the microphone is connected with the lower portion of the dustproof cloth, the upper portion of the dustproof cloth is provided with the waterproof airtight chamber, and the periphery of the waterproof airtight chamber is provided with the glue sleeve. The apparatus can be applied to a sound receiving portion of a waterproof electronic device and has the following advantages: a waterproof airtight chamber structure is employed, sound does not have to pass through a conventional waterproof membrane, the effect at a waterproof state is good, and the sensitivity of the microphone and the all-frequency-range sound receiving effect of the microphone are good; and in a normal environment, the waterproof airtight camber is unlocked, and since there is no blocking of the waterproof membrane, the sound receiving effect is better.

Description

[0001] technical field [0002] The invention specifically relates to an assembly device for a microporous waterproof front cavity and an electret condenser microphone. Background technique [0003] At present, there are quite a lot of waterproof microphones on the market, and most of them use waterproof membranes to glue the sound holes of the microphones to achieve waterproof purposes, such as figure 1 However, due to the limitation of the material of the waterproof membrane itself, the sensitivity of the microphone and the effect of full-band frequency reception will be greatly attenuated, and the electrical characteristics of the microphone itself cannot be perfectly displayed in the full frequency band. Contents of the invention [0004] The purpose of the present invention is to overcome the above problems in the prior art, and provide a microporous waterproof front cavity and an electret condenser microphone assembly device. [0005] In order to achieve the above-m...
