    A cheap wireless microphone circuit, Wireless Microphone Keywords: FM microphone, wireless microphone, c9018 A recently, a wireless microphone sold in the market is between 10 and 20 yuan. The microphone is tuned in the 88 ~ 108MHz frequency band, and the emission distance is about 30 meters, and any frequency modulated radio can be received, and the received sound is clear, no miscellaneous interference, there is no effect on the local FM station. According to the real thing, it draws its circuit diagram for the vast number of electronic enthusiasts. Circuit works. The sound is coupled to the base of the triode via the microphone through the microphone, and the low frequency blocking filter is coupled to the base of the triode. Since the positive feedback amplification of the triode, the high-frequency signal of the high-frequency oscillator composed of L1 and C3 is fed back to the triode base effect by C4. The two signals are formed together with the triode mixing (88 to 108 MHz), transmitted to the antenna via C6, and the antenna transmits the FM signal to the surrounding space. The gap of the fine tuning the L1 coil can change the frequency value of the FM frequency modulation wave. When used, the reception frequency of the FM can be selected at any 88 to 108 MHz. Selection of component L1. With the ∮ 0.6mm enameled wire around 4 turns around the ordinary ballpoint pen, the triode can be used with a high-frequency small power tube with a C9018 high frequency, and other components can be identified in the figure.
