555 audio oscillator circuit diagram of a radio-frequency drive


Posted on Mar 28, 2007

As illustrated, 555 and R1, RP1, C1 and other components controlled audio oscillator, f frequency of 1.44/(R1 + 2RP1) C1, illustrated parameters between 600Hz ~ 20kHz, can be s

elected by adjusting the RP1. The oscillator or not, depending on the reset terminal 4 foot level. When no RF signal, 4 feet was low, 555 state to stop vibration; when a designated radio frequency signal, the detector diode detector D1, the video signal is applied to pin 4, when the signal level is higher than 1V, the start-up, the speaker will be issued tone given audio signal
