Abstract

The invention relates to the technical field of audio multiplexing, in particular to a device and a piece of electronic equipment for audio multiplexing. The device comprises a narrowband communication module equipped with a first recording unit and a first sounding unit, and a broadband communication module equipped with a second recording unit and a second sounding unit, wherein the first recording unit is used for recording the sound played by the second sounding unit, and the second recording unit is used for recording the sound played by the first sounding unit. Through the scheme in theembodiment of the invention, timely and complete transmission of audio signals between the narrowband communication module and the broadband communication module can be ensured, the problem of time difference in the switching process of multiple audio switches in the prior art is avoided, and audio signals transmitted between the narrowband communication module and the broadband communication module are purer.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of audio multiplexing, and in particular, to a multiplex audio multiplexing device and electronic equipment. Background technique [0002] Private network communication technology has developed into the era of narrow-band digital intercom, but with the development of technology, the narrow-band intercom business can no longer meet the requirements of the industry. Therefore, the broadband business has been upgraded to a national strategic level. In order to ensure that the broadband business is carried out without affecting the large investment in early narrowband, the national level proposes the concept of "integrated communication", including analog and digital integration. , public network and private network integration, broadband and narrowband integration, etc. To realize wide-narrow fusion, one of the core difficulties is how to realize multi-channel audio system fusion. ...
