Communication system and method for sharing audio signals by multiple audio and video call devices

Abstract

The invention provides a communication system and method for sharing audio signals by multiple audio and video call devices, and belongs to the field of communication. The communication system provided by the invention can comprise N audio and video call devices; each audio and video call device is provided with two or more completely same audio signal interfaces; the N audio and video call devices are separately connected in pairs through the audio signal interfaces; all the audio and video call devices are connected through an audio cable; and all the audio and video call devices can communicate with other communication devices through the communication link of one audio and video call device. The invention further provides a communication method based on the communication system. The communication system and method provided by the invention have the benefits that: signal interconnecting and sharing among multiple audio and video conference devices can be effectively realized; loudspeakers and microphones of different devices cannot form a sound feedback loop; connection is simple; and the connection number is not limited.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication system and method for sharing audio signals among multiple audio and video call devices. Background technique [0002] Currently commonly used communication terminal equipment such as telephones, mobile phones and other products, as well as audio and video equipment connected to computers, smart devices, etc. for audio and video communication, such as omnidirectional microphones, USB conference phones and other products, all work stand-alone. [0003] Each device uses an independent communication line, has a set of independent microphones and speakers, and there is no inter-connection design for incoming and outgoing audio between different devices, or although there is an interconnection or shared design, but the connection method is different from this method, there are The connection scheme only connects one signal in the microphone or the speaker. [0004] Two or mo...

AI Technical Summary

Problems solved by technology

Although the hands-free call equipment using digital signal processing technology (DSP) can achieve a relatively good hands-free call effect and meet the needs of multi-person calls, when the participants are far away from the microphone and speakers, they still Can’t hear the sound of the speaker clearly, and the microphone’s reception effect is also not ideal

[0006] Although some products provide a multi-machine working method, some only share one signal from the microphone or speaker, or the connection is not as simple and easy as this method, and the number of connections is also limited.
