This novelbuzzer circuituses a relay in series with a smallaudio transformer and speaker. When the switch is pressed, the relay will operate via thetransformerprimary and closed relay contact. As soon as the relay operates the normally closed contact will open, removing power from the relay, the contacts close and the sequence repeats, all very quickly…so fast that the pulse of current causes fluctuations in the transformer primary, and hence secondary. The speakers tone is thus proportional to relay operating frequency. The capacitor C can be used to “tune” the note. The nominal value is 0.001uF, increasing capacitance lowers the buzzers tone.source : zen’s circuit collections
