Abstract

The invention provides a mobile terminal. The mobile terminal provided by the invention comprises a shell; a pickup hole is formed in the shell; a microphone, a circuit board, a waterproof membrane bracket, a waterproof membrane and a sound receiving bracket are arranged in the inner cavity of the shell; the waterproof membrane is stuck on the waterproof membrane bracket and is supported against the pickup hole which is located at the inner sidewall of the shell; the microphone is arranged on the circuit board; a sound receiving through hole which is opposite to the waterproof membrane is formed in the waterproof membrane bracket; the sound receiving bracket is connected with the shell; the sound receiving bracket is provided with a through hole; one end of the through hole is opposite to the sound receiving through hole of the waterproof membrane bracket while the other end thereof is opposite to the receiving end of the microphone, so that a sound conduction channel is formed between the pickup hole and the receiving end of the microphone; and the circuit board is electrically connected with the microphone to drive the microphone to receive sound. According to the mobile terminal, a microphone sealing and waterproof structure with good sealing and high reliability can be realized.

Description

technical field

[0001] The present invention relates to mobile terminal technology, in particular to a mobile terminal. Background technique

[0002] At present, with the popularity of mobile terminals such as mobile phones, more and more attention has been paid to the three-proof (dustproof, waterproof, drop-proof) performance of mobile terminals. Among them, the waterproof performance of mobile terminals such as mobile phones has always been one of the focuses.

[0003] At present, the outer shells of mobile terminals such as mobile phones are integrally sealed, and the shells are provided with key grooves, sound pickup holes for microphones to pick up sound, and the like. Among them, the sound pickup hole of the microphone is located at the end of the mobile phone casing, and is generally a through hole that runs through the inside and outside of the mobile phone casing. Usually, a microphone waterproof structure is provided to perform waterproof and sealing treatment o...
