Terminal having audio communication function and method for picking up sound signal thereof

Abstract

The invention provides a terminal having an audio communication function and a method for picking up a sound signal thereof. The terminal comprises a shell, a circuit board arranged inside the shell, and a USB (Universal Serial Bus) slot formed in the shell, wherein a main microphone unit and a noise-reducing microphone unit are fixed on the circuit board; a cavity component is arranged outside the main microphone unit; the circuit board, the cavity component and the shell form the additional cavity of the main microphone unit in a cooperative manner; a communicating structure is arranged between the additional cavity and the USB slot; the communicating structure forms a sound inlet channel of the main microphone unit; the shell is provided with a preserved gap which forms a sound inlet channel of the noise-reducing microphone unit. By using the terminal having the audio communication function, the internal space of a product can be saved, a small number of structural parts are used, a microphone can be placed flexibly, and high acoustic performance is realized.

Description

technical field [0001] The present invention relates to the technical field of sound-to-electricity conversion, and more specifically, to a terminal with an audio communication function and a method for picking up sound signals. Background technique [0002] With the progress of society and the development of technology, communication products such as mobile phone equipment, hands-free equipment and head-mounted equipment play an increasingly important role in daily life and in the field of patents. At the same time, with the continuous increase of traffic noise and living noise and the improvement of users' requirements for call quality, the acoustic performance of a single microphone is no longer sufficient to meet the needs of users, so the dual-microphone solution is more and more frequently used in actual products. [0003] At present, the communication voice frequency range popularized in our country is 300Hz ~ 3400Hz, that is, narrowband voice communication. This fre...
