As shown in Figure 9-35, 555 and R1, RP1, C1 form an astable multivibrator, the oscillation frequency f = 1.44 / (R1 +2 R2) C1. The frequency can be adjusted by RP1. Its output is output by the audio step-up transformer T, it may realize the conversion of DC to AC. Selecting the audio output frequency and designing transformer T is according to the actual needs.
