Embodiment Construction

[0019] Such as figure 1 As shown, in the embodiment of the present invention, a wireless audio communication system is provided, which includes multiple wireless audio communication subsystems with the same communication frequency band, wherein each wireless audio communication subsystem includes a host and a It is a wireless sub-machine for the above-mentioned host to perform wireless communication.

[0020] Each host includes an MCU and an audio communication chip CC8520. Further, each host also includes a coordination signal input port IN, a coordination signal output port OUT and a shielded ground interface GND. Each master has two modes of coordination master and coordination slave, and the default working mode of each master is the coordination master mode. When the MCU of a certain master detects that the coordination signal input port receives the coordination signal, the master Automatically switches to coordinated slave mode. In the coordinating host mode, the MCU...

Abstract

The invention discloses a wireless audio communication system and a communication method. The wireless audio communication system comprises a plurality of wireless audio communication subsystems withthe same communication frequency band. wherein each wireless audio communication subsystem comprises a host and a wireless auxiliary machine which is in wireless communication with the main machine; each host comprises a coordination signal input port and a coordination signal output port; a plurality of hosts of the plurality of wireless audio communication subsystems are set as a coordination host and at least one coordination slave. wherein a coordination signal output port of the coordination host is connected with a coordination signal input port of the coordination slave, and the coordination host is used for sending a coordination signal to the coordination slave so as to coordinate and control signal receiving and transmitting time sequences of the plurality of wireless audio communication subsystems. According to the invention, the problem of signal interference among a plurality of wireless audio communication subsystems can be solved.

Description

technical field [0001] The present invention relates to the field of wireless audio transmission, in particular to a wireless audio communication system based on the CC8520 wireless audio solution and a communication method thereof. Background technique [0002] TI's CC (CC85XX) series wireless audio communication chips work in the range of ISM channel 2400M-2483M, with a total of 18 working channels, with optional bandwidth of 2M and 5M. Support two-way transmission of audio data and control data, among which audio data supports multiple sampling rates of 32K, 40.275K, 44.1K, and 48K; control data supports two-way transmission, which increases the flexibility of control. It is mainly used in wireless microphones, wireless earphones, Wireless speakers and many other wireless audio products. [0003] A set of CC (CC85XX) series wireless audio products usually includes a host and a slave. The host is responsible for the establishment and maintenance of the network. In the cas...
