Problems solved by technology

[0003] However, during use, impurities outside the microphone module can also enter the accommodation cavity through the sound receiving hole and fall on the vibrating diaphragm
When more and more impurities fall on the vibrating diaphragm, with the normal vibration of the vibrating diaphragm, these impurities are easy to scratch and puncture the vibrating diaphragm, affecting the normal use of the microphone module

Abstract

The invention provides a microphone module and a terminal, and relates to the technical field of terminals. The microphone module comprises a circuit board provided with a sound receiving hole; a signal converter used for converting a sound signal into an electric signal and comprising a shell with an accommodating cavity, wherein the signal converter is connected with the circuit board, and the sound receiving hole communicates with the accommodating cavity; and an adhesion piece arranged in the accommodating cavity. According to the microphone module, the possibility that impurities contacta vibrating diaphragm is reduced through the adhesion piece arranged in the accommodating cavity of the signal converter, so that the impact and abrasion of the impurities to the vibrating diaphragm are reduced, the vibrating diaphragm is prevented from being damaged, the normal use of the microphone module is guaranteed, and the service life of the microphone module is prolonged.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular, to a microphone module and a terminal. Background technique [0002] Microphone modules are an indispensable part of terminal equipment. Typically, a microphone module includes a signal converter and a circuit board. Wherein, the signal converter includes a casing formed with an accommodating cavity, and a vibrating diaphragm located in the accommodating cavity; a sound receiving hole is arranged on the circuit board. The signal converter is connected to the circuit board so that the vibrating diaphragm corresponds to the receiving acoustic hole. The sound signal is transmitted into the accommodation cavity through the sound receiving hole, driving the vibrating diaphragm to vibrate, and then the signal converter converts the sound signal into an electrical signal. [0003] However, during use, impurities outside the microphone module can also enter the accommodat...
