As voice synthesizing techniques with ICs and LSIs
are rapidly progressed, human voice synthesizing
devices are put into practical use for portable
calculators, clocks, vending machines, translating
machines and so forth. In order to meet the demand,
Murata has developed.
Piezoelectric Speaker best suited for making
synthesized voice or melody.
1. High efficiency compared with conventional
2. Ultra-thin and light-weight.
3. High impedance with less power consumption.
4. No electric noise, because they have no mechanical
5. Direct drive by IC is available.
