Embodiment Construction

[0034] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details. For the sake of brevity, components other than the microphone on the circuit board of the terminal with audio communication function of the present invention have been omitted, and will not be described in detail.

[0035] Due to the increasingly higher requirements for the acoustic performance of the transmitting end of handheld devices, hands-free devices, head-mounted devices, etc., the design scheme of dual microphones is more and more widely used in actual products. The audio communication function of the present invention Terminals are not limited to products such as communication headsets, but can also be applied to communication products such as mobile phones with slots, car hands-free and other...

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...
