压电陶瓷，一种能够将机械能和电能互相转换的功能陶瓷材料。在能量转换方面，利用压电陶瓷将机械能转换成电能的特性，可以制造出压电点火器、移动X光电源、炮弹引爆等装置。 压电陶瓷具有敏感的特性，可以将极其微弱的机械振动转换成电信号，可用于声纳系统、气象探测、遥测环境保护、家用电器等。声音转换器：声音转换器是最常见的应用之一。像拾音器、传声器、耳机、蜂鸣器、超声波探深仪、声纳、材料的超声波探伤仪等都可以用压电陶瓷做声音转换器。如儿童玩具上的蜂呜器就是电流通过压电陶瓷的压电效应产生振动，而发出人耳可以听得到的声音。压电陶瓷通过电子线路的控制，可产生不同频率的振动，从而发出各种不同的声音。例如电子音乐贺卡，就是通过压电效应把机械振动转换为交流电信号.通过外界的声音，将声音产生的振动放大，把放大的振动施加在压电陶瓷上，压点陶瓷受到压力，产生电能。再把装置连接一个储电装置，将转化的电能储蓄，要用的时候再用。

Piezoelectric ceramics, a mechanical and electrical power to each other the function of the conversion ceramic materials. In energy conversion, use of piezoelectric ceramic mechanical energy into electrical energy conversion to the characteristic, can make piezoelectric ignition, mobile X-ray power supply, shells detonated devices. Piezoelectric ceramics has the characteristics of sensitive, can will be very weak mechanical vibration into electrical signal, and can be used in the sonar system, meteorological observation, telemetry environmental protection, household electric appliances, etc. Voice converter: voice converter is the most common of the application. Like pick-up, microphones, headset, a buzzer, ultrasonic apparatus, sonar, deep exploration of the materials can be used by ultrasonic flaw detector, piezoelectric ceramic do voice converter. Such as children's toys is current through the bee blare of piezoelectric ceramic piezoelectric effects of vibration, and sent by ear can hear voice. Piezoelectric ceramic through the electronic circuit to control, can produce different frequency of vibration, thus send all the different sound. Such as electronic music greeting CARDS, is through the piezoelectric effect the mechanical vibration conversion of ac electric signals. Through the external sounds, will sound vibrations amplifier, the amplification of the vibration on the piezoelectric ceramics, pressure points by ceramic pressure, to generate electricity. The devices connected to a store electric device, the electrical energy savings will be transformed, want to use to be used.

Piezoelectric ceramic, capable of converting mechanical energy into electrical energy and mutual conversion of the functions of ceramic materials. In energy conversion, the use of piezoelectric ceramics to mechanical energy into electrical energy conversion characteristic, can create a piezoelectric igniter, mobile X optical power supply, such as artillery shells detonated device. Piezoelectric ceramic with sensitive characteristics, can be an extremely weak electrical signals into mechanical vibration, can be used for sonar system, weather detection, remote sensing of environmental protection, such as household appliances. Converter voice: the voice of converter is one of the most common applications. Like a pickup, microphone, earphone, buzzer, ultrasonic detection of deep-yee, sonar, ultrasonic flaw detector materials can all use piezoelectric ceramics sound converter. Such as children's toys on the buzzer is the current through the piezoelectric vibration effect, and the issue of the human ear can hear sound. Piezoelectric ceramics by electronic circuit control, can produce different frequency of vibration, thus make the different sounds. Such as electronic music card, is through the piezoelectric effect to convert the exchange of mechanical vibration signals. Through the voices of the outside world, the vibration sound amplification, the amplification of the vibration applied to the piezoelectric ceramic on ceramic pressure point, under pressure, to generate electricity. The device connected to a storage device, will be transformed into energy savings, and then use the time.
