By applying the piezoelectric technology built upon years of experience, we offer filters, discriminators, and resonators suitable for all types of circuits. For filters and discriminators, by selecting the rank of the center frequency, the interface circuit can be made non-adjustable. Our resonators can be optimized for the latest model ICs, special-purpose ICs, and custom ICs. In addition, our buzzer lineup offers two types. You can choose from the electromagnetic type which delivers high acoustic pressure with a relatively wide frequency range, and the piezoelectric type which is compact, low voltage, and energy saving. We offer the option with or without the drive circuit for both types.
