Piezoelectric Sound Components

Piezoelectric Sounders External Drive Lead Wire Type

Now 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.

s Features

1. Low power consumption

2. No contacts therefore, no noise and highly reliable

s Applications

1. Telephone ringers

2. Various office equipment such as PPCs, printers and

keyboards

3. Various home appliances such as microwave ovens

4. Confirmation sound of various audio equipment
