Embodiment Construction

[0041] In order to enable those skilled in the art to better understand the solution of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners.

[0042] Before introducing the technical solutions of the present invention, the application scenarios of the present invention are first explained.

[0043] As we all know, for a communication device (such as a mobile phone, a tablet computer, etc.) with functions of calling and playing sound, the basic components include a speaker for playing sound and a microphone for receiving sound. Among them, the speaker is used to convert the received electrical signal into an acoustic signal for sound playback, and the mic is used to convert the collected acoustic signal into an electrical signal for transmission. The speaker and mic are independent of each other and realize their respective functions.

Abstract

Discloses are a verbal system, and a switching method and a device which are applied to the verbal system. The method comprises judging whether a preset switching signal is collected; and switching a loudspeaker of the verbal system into a sub microphone so that the sub microphone and a microphone possessed by the verbal system form a double-microphone when the preset switching signal is collected. The loudspeaker of the verbal system has an electro-acoustic conversion function and an acoustic-electric conversion function at the same time; and, in a scene that the double-microphone needs to be used, the loudspeaker is converted into the microphone and cooperates with the microphone possessed by the verbal system to form the double-microphone. So design requirements of the microphone and a loudspeaker which are possessed by the verbal system can be reduced, an internal structural space of the verbal system can also be saved, and the fact that thin and light design of the system is achieved is facilitated.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication device and a switching method and device applied to the communication device. Background technique [0002] With the continuous development of information technology, communication devices such as mobile phones have become indispensable electronic devices in people's daily life. The speaker (speaker) in the communication device is used to realize the conversion of electrical signals to acoustic signals, and is used in the case of hands-free calls, incoming ringtones, music playback, etc.; the microphone (mic) in the communication device is used as a sound receiving device for It realizes the conversion of acoustic signal to electrical signal, and is used in situations such as handheld calls and recordings. [0003] In the prior art, in order to improve the clarity of the user's call and improve the noise reduction effect, most call devices have built-in 2 ...
