Problems solved by technology

In the existing technology, the private network (intercom function) is only an accessory of the public network (mobile phone function), and it is mainly used as a backup call mode when the signal of the public network (mobile phone function) is poor. In the case where public network and private networ

Example Embodiment

[0044] Example 1:

[0045] First, some terms mentioned in the embodiments are explained: public network communication refers to mobile phone communication methods including 2G, 3G, etc., while private network communication refers to walkie-talkie communication methods. In the communication process, uplink communication refers to the process in which the audio receiving device receives the voice and then sends it out through the antenna, while the downlink communication refers to the process in which the voice signal is received by the antenna, and then the voice is played by the audio player.

[0046] Such as figure 1 As shown, an audio system with both mobile phone and walkie-talkie call functions includes a public network audio system, a private network audio system, and a switch 4.

[0047] The public network audio system is used to process the audio of mobile phone calls. It includes a public network audio processing circuit 21, a public network radio frequency circuit 22, and a ...

Abstract

The invention discloses an audio system having mobile phone and intercom call functions. The audio system comprises a public network audio system, a private network audio system and a diverter switch. The public network audio system is used to process mobile phone call audios. The public network audio system comprises a public network audio processing circuit, a public network radio-frequency circuit and a public network antenna which are serially connected successively. The private network audio system is used to process intercom call audios. The private network audio system comprises an inverting adder, a private network audio processing circuit, a private network radio-frequency circuit and a private network antenna which are serially connected successively. The inverting adder is connected with the public network audio processing circuit. The audio system of the invention has the following advantages that the random switching between mobile phone and intercom call functions can be realized; the number of audio playing devices can be reduced, and the audio system is suitable for a variety of different types of audio playing devices; the recording function is further provided, the public network and private network call voice recoding can be realized through a public network audio processing chip; and the inverting adder is added, so that the circuit structure is greatly simplified.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to an audio system having the call function of a mobile phone and a walkie-talkie. Background technique [0002] Most of the existing public network (2G / 3G mobile phone call) and private network (walkie-talkie call) coexistence designs are "mobile phone with walkie-talkie function", that is, an walkie-talkie module is added to the mobile phone communication chip, and its main function is a mobile phone. The walkie-talkie is an auxiliary function. In the existing technology, the private network (intercom function) is only an accessory of the public network (mobile phone function), and it is mainly used as a backup call mode when the signal of the public network (mobile phone function) is poor. It is suitable for the situation that both the public network and private network call modes are required to be valid under any circumstances. In addition, the existi...
