Abstract

A radio blue wave emitting device includes a radio emitting module, an audio input end and a supply module, in which, the radio emitting module and the supply module are connected with the CPU of a TV mainboard and controlled by the CPU, said audio input end is connected with the wire signal interface of the TV to receive audio signals and transmit them to the radio emission module, which transfers the audio signals to radio signals and emits them to radio signal receiving devices with earphones, said radio emission module also includes a FM module to write in frequency point data in said FM module by the CPU of the mainboard and design the frequency points, which can set 'on' and 'off' of radio blue waves and frequencies in the menu of TV to solve the problem of mutual interference caused by the same emitting frequency points of the radio emission module and the radio broadcast stations.

Description

【Technical field】 [0001] The invention relates to a TV set, in particular to a wireless blue wave transmitting device of the TV set which can control the frequency point. 【Background technique】 [0002] Current TV sets rarely have wireless transmission capabilities. The TV set with the function of wireless transmission is a wireless transmission module that cannot control the frequency and is composed of an external discrete component through the audio output port. This will cause the transmission frequency of the module to be the same as that of the wireless broadcasting station, causing mutual interference. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a wireless blue wave transmitting device that can control the frequency point to overcome the above problems. [0004] In order to solve the above problems, the present invention provides the following technical solutions: a wireless blue wave transmitting devic...
