Abstract

The embodiment of the invention discloses a microphone with a waterproof function. The microphone comprises a substrate and a packaging shell, wherein the substrate is provided with a microphone assembly; the packaging shell is arranged at the top of the substrate; the packaging shell is provided with a plurality of waterproof sound holes; and the packaging shell is connected with substrate in a sealing manner. According to the invention, the waterproof sound holes are formed in the packaging shell of the microphone, water drops are prevented from entering the microphone through the waterproofsound holes, sound signals are not influenced to enter microphone, the tension principle of water can be utilized, and the water drops cannot enter the microphone through the waterproof sound holes,so that the microphone has the waterproof function, the acoustic performance of the microphone is not affected, a waterproof film is not needed, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to the field of microphones, in particular to a microphone with waterproof function. Background technique [0002] MEMS (micro-electromechanical systems) microphones, MEMS microphones can provide high performance and fidelity and reliability for microphones in a compact size, suitable for portable devices. It can be manufactured by surface mount technology, can withstand high reflow temperature, is easy to integrate with CMOS technology and other audio circuits, and has improved noise cancellation performance and good RF and EMI suppression performance. [0003] Existing microphones are rarely waterproof. Existing microphones with waterproof function can be equipped with a waterproof membrane on the outside or inside of the microphone, but the waterproof membrane will block the transmission of a part of the sound signal, and this waterproof microphone will weaken the volume and reduce the volume and sound quality of the microphon...
