Windproof microporous waterproof type electret condenser microphone

Abstract

The invention discloses a windproof microporous waterproof type electret condenser microphone. The windproof microporous waterproof type electret condenser microphone comprises a sound reception hole and an ABS case, wherein the sound reception hole is arranged at a middle part of an upper end of the ABS case; a Mylar film is arranged inside the ABS case and below the sound reception hole; a waterproof airtight chamber is arranged below the Mylar film; a lower end of the waterproof airtight chamber is connected with dustcloth; a lower end of the dustcloth is adhered with the microphone; the lower part of the microphone is sealed by waterproof epoxy glue; and a welding spot of the microphone is connected with a wire rod. The windproof microporous waterproof type electret condenser microphone provided by the invention has the advantages of being ventilate and waterproof; a waterproof airtight chamber structure is adopted, sound does not need to travel through a traditional waterproof membrane, so that the effect is good, the microphone sensitivity and microphone full-band sound reception effect are good under a waterproof state; besides, under a normal environment, the waterproof airtight chamber is unblocked, since no blocking of the waterproof membrane exists, the sound reception effect is more ideal, and the waterproof airtight chamber has a windproof effect, so that the application is more diversified and convenient.

Description

technical field [0001] The invention relates to a microphone, in particular to a windproof microporous waterproof electret condenser microphone. Background technique [0002] At present, there are quite a lot of waterproof microphones on the market, and most of them use a waterproof membrane to glue the sound hole of the microphone to achieve waterproof purposes. However, due to the material limitation of the waterproof membrane itself, the sensitivity of the microphone and the effect of full-band frequency reception will be greatly reduced. Attenuation, and there is even a lack of waterproof microphones that are both windproof and waterproof. At present, the electrical characteristics of windproof and waterproof microphones are average in the entire frequency range of 100Hz-20KHz, and the sound reception effect is not ideal. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a windproof m...
