Wireless audio repeaters are widely used in wireless headsets, car MP3 transponders, conference broadcasts, buildings and park broadcasts. The simplest wireless audio repeater can be constructed with only one transistor, as shown in the following figure: Figure 1 Single-tube audio FM repeater The above figure uses a triode 9018 to form an oscillator. The audio signal is input from the base of the triode, and the frequency modulation is achieved by the varactor characteristics of the BE junction. Although the circuit is simple, the sound quality is very poor, the stability of the oscillating circuit is very bad, and the change of the voltage, the appearance of the human body or the metal object near the antenna will change the oscillation frequency and cause the instability of the receiving end. Moreover, the circuit can only transmit mono audio, and users cannot hear high-quality stereo music.
