They are based on the ability of the piezoceramic discs to vibrate at the frequency of the applied voltage, when applying a voltage between their two faces.When that frequency corresponds to the resonance amplitude is maximum a high acoustic level is achieved with low consumption, size, weight reduced and without interference.
Suitable for use in electronic toys, watches, telecommunications, alarms, etc.
