Introduction
Murata is active in R&D of new electronic components, seeking infinite possibilities with ceramic materials. Particularly, as a pioneer in the development of piezoelectric ceramics, Murata has met the needs of the technical revolution in electronics with original products. Ourceramic resonators (CERALOCK®), ceramic filters (CERAFIL®), piezo buzzers and various ultrasonic transducers have contributed to the development of electronics. The "Piezoelectric sound components" introduced herein operate on an innovative principle utilizing natural oscillation of piezoelectric ceramics. Today, piezoelectric sound components are used in many ways such as home appliances, OA equipment,audio equipment telephones, etc. And they are applied widely, for example, in alarms, speakers, telephone ringers, receivers, transmitters, beep sounds, etc. This manual is made for customers to use piezoelectric sound components efficiently and with no trouble. It is recommended that the manual be read while referring to the catalog.
