2 INTRODUCTION Recently, technological innovations are being rapidly introduced in the area of Office Automation (OA) equipment, VCR, and Communication equipment, etc.. The core technologies behind these innovations are multifunction, down-sizing and weight reduction. URATA, as the leader of technologies for piezoelectric ceramics, has been successing to develop various unique products which meet needs in the advanced information society. The "piezoelectric sound component", which is introduced herein, is also one of URATA's original products. Piezoelectric sound components are now drawing attention widely as suitable components for various electronic equipment like as OA equipment (ex. word-processor, typewriter, AX machine, etc..),audio equipment (ex. radiocassette, tape recorder, etc..), and telephone sets. Also, the application range is expanding from a monitor sound for the controller to time signal, alarm, speaker, ringer and receiver for telephone set. So, now piezoelectric sound components are working as an " interface" between human and electrical equipment. This catalog is providing various types of piezoelectric sound component which could help design of equipments to lead the best solution. CERAITONE (Piezoelectric Speaker), CERAIPHONE (Piezoelectric Receiver) and PIEZORINER (Piezoelectric Ringer) are the trademark of urata anufacturing Co., Ltd.

17 PIEZOELECTRIC SPEAKER Piezoelectric Speaker (CERAITONE ) 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, urata has developed Piezoelectric Speaker best suited for making synthesized voice or melody.!eatures 1. High efficiency compared with conventional electromagnetic type speakers. 2. Ultra-thin and light-weight. 3. High impedance with less power consumption. 4. No electric noise, because they have no mechanical contacts.. Direct drive by IC is available. VSB3EW-01B VSBEW-0301B!NOTICE 1. Please pay full attention not to subject piezoelectric sounder to DC voltage for long periods. 2. Protect LSI by using a varistor or zener diode. External heat or mechanical shock makes piezoelectric sounder to generate several Vp-p voltage.!speciications req. Range [Hz] Capacitance [n] (120Hz) Impedance [Ω] (1kHz) Lowest Resonant req.
