Piezoelectric Sound Components
Piezoelectric Sounders External Drive Lead Wire Type
Microcomputers are widely used for microwave
ovens, air conditioners, cars, toys, timers, and other
alarm equipment. Externally driven piezoelectric
sounders are used in digital watches, electronic
calculators, telephones and other equipment. They are
driven by a signal (ex.: 2048Hz or 4096Hz) from an LSI
and provide melodious sound.
■ Features
1. Low power consumption
2. No contacts therefore, no noise and highly reliable
■ Applications
1. Various office equipment such as PPCs, printers and
keyboards
2. Various home appliances such as microwave ovens
3. Confirmation sound of various audio equipment
