Problems solved by technology

[0004] 1) In the mobile phone terminal with walkie-talkie function, the private network (walkie-talkie function) is only an accessory of the public network (mobile phone function), and is mainly used when the signal of the public network (mobile phone function) is poor. Alternate call mode, it is not suitable for the situation where both public network and private network call modes are valid
[0005] 2) The mobile phone with the function of walkie-talkie only realizes the communication method of integrating the function of walkie-talkie on the mobile phone, and does not make corresponding improvements to the audio system, which greatly reduces the actual voice effect
[0006] 3) The left and right channels of the mobile phone with the existing intercom function cannot be controlled separately

Abstract

The invention relates to a time-sharing control system for left and right channels based on an Android platform, including an Android system, an audio circuit control module, a communication module, a cluster intercom module, an audio input module, an audio processing module, an analog switch unit, a selection switch and an audio Output module; before the secondary analog mixing module, analog switches are respectively set on the left channel and the right channel, so as to control the left and right channels in time-sharing. The invention can realize the time-sharing control of the left and right sound channels and meet the requirements of multi-speech environments.

Description

technical field [0001] The invention relates to the technical field of voice communication, in particular to a multi-voice fusion communication system based on an Android platform, specifically a time-sharing control system for left and right audio channels based on an Android platform. Background technique [0002] With the development of the current communication technology, more and more communication devices appear. Usually, the voice communication method adopted by the existing multifunctional communication device is to use the operator's network (i.e. mobile public network) to make a call, or use a regional intercom network (that is, a private network) to make an intercom call. However, the existing voice communication method cannot use the operator network to realize the regional intercom function, nor can it utilize the regional intercom network to realize the public network mobile communication function. Such a voice communication method has relatively large limita...
