sales representatives or product engineers before ordering.
!Note
As the result of rapid development of ICs in
telephones, demand for piezoelectric sounders as
telephone ringers has also rapidly increased. To
effectively satisfy this rising demand, Murata
provides a suitable piezoelectric sounder called
"PIEZORINGER" with the following features.
1. Extremely clear sound
2. Since it is voltage driven, the power consumption
3. It can be driven directly from ICs.
4. Thin and lightweight
