Electronic buzzers are sound emitters or signal, electromechanical, electronic or piezoelectric devices. They turn a DC into a discontinuous or alternating current. During operation, they emit a cracking or buzzing sound. A wide range of the Little Diode store includes a wireless buzzer and other buzzers, which are applied in the following spheres:
• in phones;
• in telephony (serve for the transmission of necessary acoustic signals (information signals) to ATS subscribers and to the operators of hand-held long-distance telephone exchanges);
• in military telephony (instead of an inductor);
• in dosimeters;
• in radio engineering (when setting up the detector, for various measurements, etc.);
• in typewriters (serve to provide a sound signal indicating the completion of training or the sudden stoppage of the machine);
• in various annunciators;
• in alarm devices;
• in the electronic clocks;
• in the household appliances;
• in toys (in this case, a 12v buzzer will be enough).
