Piezoelectric Sound Components
Piezoelectric Buzzers
This is a unified piezoelectric sounder which has a
piezoelectric diaphragm of 3 terminals connected to a
self drive circuit, and it easily generates sound with
only a DC power supply (DC3.0-20V). Using suitably
designed resonant system, this type can be used where
large sound volumes are needed.
■ Applications
1. Gas alarms, burglar alarms
2. Air conditioners, microwave ovens and various types
of microcomputer controlled home-electronic
appliances
3. Toys, games, and other simple electronic devices
such as teaching aids
