The active piezo buzzer is an integrated electronic sounder that is powered by DC voltage and is widely used in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronics, telephones, timers, etc. Sounding device. BOMBINATOR maxime dividitur in duas genera Piezo buzzer et Magna BOMBINATOR .The Piezoelectric Buzzer est maxime composito ex multivibrator, a piezoelectric Buzzer, impedimentis matching fabrica, a resonatur arca, et exterius armamentis et simile. Quidam Piezoelectric Buzzer Housings sunt etiam instructa lumen, emittendo Diodes.
