Abstract

The invention discloses a wireless audio device and a wired audio relay method based on the wireless audio device. The wireless audio device comprises a power supply module and a first audio interface. The first audio interface is divided into two branches, one branch is directly connected with a second audio interface, and the other branch is connected with the input end of a signal conversion module. The output end of the signal conversion module is connected with a wireless transmit-receive module. The control ends of the signal conversion module and the wireless transmit-receive module are respectively connected with a controller module. The method is that an audio signal received by the first audio interface is transmitted out in a wired way via the second audio interface or transmitted to the wireless transmit-receive module via conversion of a signal conversion circuit. The audio signal is emitted out in a wireless way by the wireless transmit-receive module so that a problem in the prior art that wireless audio and wired audio cannot be used simultaneously is overcome, and wireless transmission of the audio signal is realized by the method without damaging the original wired connection mode.

Description

technical field [0001] The invention belongs to the technical field of wireless audio equipment, and relates to a wireless audio equipment and a limited audio relay method based on it. Background technique [0002] The wireless audio equipment currently on the market all work in the way of "terminal", which is either a transmitting device or a receiving device. In this way, it is impossible to add wireless terminals without destroying the original wired audio system connection mode. For example, if you want to transmit the audio signal of the TV to the wireless headset through a wireless device, you must remove the original audio signal cable from the TV and connect it to the wireless audio transmitter before you can use the wireless audio headset to receive the TV audio. Signal. In this way, when you want to use wired audio equipment, such as audio power amplifiers, and wireless headphones at the same time, conflicts will occur; or when switching between wired and wireles...
