Problems solved by technology

[0004] The inventor of this patent found in the process of research and practice in the prior art: in the above solution, during the use of the mobile terminal, when the rubber sleeve used for sealing is squeezed from the casing above it, it is easy to Deformation occurs, and the microphone becomes a force-bearing body, which leads to poor audio performance consistency of the microphone, and unknown noises are prone to occur when the shell is squeezed
In addition, the microphone will be damaged in the long run, and it is difficult to guarantee the stability of the microphone

Abstract

The invention provides a mobile terminal with a microphone. The mobile terminal comprises a shell and a circuit board which is arranged in the shell, wherein the shell is provided with a sound inlet passage; the shell is provided with an extension part on the inner side corresponding to the sound inlet passage; an electret microphone is placed in an accommodating cavity formed by the extension part; and a sound receiving face of the microphone faces the sound inlet passage and the microphone is fixed on the circuit board through an electrical connection part at the other end. Due to the design of the mobile terminal, the consistency of audio frequency of the microphone can be guaranteed, and the audio frequency performance can be improved.

Description

technical field [0001] The invention belongs to the technical field of microphones, in particular to a mobile terminal with a microphone. Background technique [0002] Microphones, also known as microphones, microphones, microphones, etc., are energy conversion devices that convert sound signals into electrical signals. Microphones have been developed from resistive conversion to inductive and capacitive conversion. A large number of new microphone technologies gradually developed. Electret microphone is a kind of condenser microphone. Because of its simple production process and low cost, it is suitable for mass production. At the same time, it is small in size and convenient to use. In communication systems such as telephones, cameras, repeaters and mobile phones and other portable electronic devices. [0003] For electret microphones, in order to achieve better sound quality, it is necessary to consider the design of its sound inlet channel. refer to figure 1 A sectio...
