TDK PS Piezoelectronic Buzzers are high-performance buzzers that employ unimorph piezoelectric elements and are designed for easy incorporation into various circuits. These buzzers feature lower power consumption than electromagnetic units. TDK PS Piezoelectronic Buzzers serve as both a musical tone oscillator and a buzzer due to their design for external excitation. The PS series can be used with automated inserters. Applications include electric ranges, washing machines, computer terminals, and devices requiring speech synthesis input.
