!Note
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.
1. Gas alarms, burglar alarms
2. Air conditioners, microwave ovens and various types
3. Toys, games, and other simple electronic devices
