TDK Product Features

TDK's piezoelectric buzzers are sounding bodies that use unimorph piezoelectric vibration plates and feature small sizes, low voltages, and loud sound volumes, as well as high performance and a design that allows for easy mounting on circuits. Since these buzzers are separately-excited oscillation, they accommodate flexible designs as music tone speakers or buzzers. The buzzers are available in various types, including those that accommodate automatic inserters that fit the needs of each company, moisture-proof type, and a type with double-sided tape.
