After being amplified, it is sent by the infrared emitter, and the infrared signal is received by the infrared ray. After receiving, the tuned circuit intercepts and RF amplification, the local oscillating circuit is used to remove the RF carrier, and then the intermediate frequency and amplification, and the detection circuit converts into an audio signal, after audio amplification and sound quality, volume control Then, the output of the sound age number is 'by this'. The creator has deliberately researched and improved the creation of this creation because of the lack of familiarity and the different connection methods with the creation circuit. M325695 [New content] The main purpose of this creation is to provide the audio that is introduced by the microphone, which is difficult to receive, and then converted into an infrared signal to be emitted by the infrared emitter. The receiver receives, then tunes and mixes, and the detection circuit converts into an audio signal output, and the audio signal is transmitted through the microphone to the infrared switching device of the scaleless wind.
