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 public network and private network call modes are required to be valid under any circumstances
[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 makes the actual voice effect greatly reduced

Abstract

The invention relates to a multi-voice fusion communication method based on an Android platform. z1 , the local audio input module will collect the local audio signal through the analog switch S z1 It is sequentially sent to the left analog mixing module and the left analog-to-digital conversion module through the left input terminal of the Android system to complete the left channel recording; and / or the right dart channel recording: the Android system turns on the analog switch S through the audio circuit control module y1 , the local audio input module will collect the local audio signal through the analog switch S y1 It is sequentially sent to the right analog mixing module and the right analog-to-digital conversion module through the right input terminal of the Android system to complete the right channel recording. The call function of the walkie-talkie of the present invention is no longer an auxiliary function of the call function of the mobile phone, and the call function of the mobile phone and the walkie-talkie can be switched at any time.

Description

technical field [0001] The present 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 voice communication that simultaneously supports satellite communication, private network communication (trunk intercom, ELTE, etc.), public network mobile communication method. 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 multi-function communication devices is that when talking with other devices, 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 netwo...
