电声换能器电声换能器electroacoustictransducer将电(声)信号能量转换成相应的声(电)信号能量的器件。一般电声换能器的能量转换过程是:对于电-声转换是先将电信号转换成机械振动,然后由机械振动产生声波;对于声-电转换,则是先将声信号转换成机械振动后再转换成电信号。电机械换能器按转换机理可分为5种:电动换能器、电磁换能器、静电换能器、压电换能器、磁致伸缩换能器等。它们的能量转换是可逆的。还有一类换能器的能量转换是不可逆的,其中应用最多的是变阻换能器,如电话机中的炭粒送话器。常用的电声换能器有:送话器和受话器,大量应用在电话机中;扬声器,主要用在可听声频范围内,将电信号转换成声信号;传声器,在可听声频范围内将声信号转换成电信号;超声换能器,用于超声波范围的电声换能器,主要是压电陶瓷换能器;水声换能器,又称水听器,接收水声信号并将其转换成电信号。近代新出现的激光换能器和光导纤维换能器是应用光干涉仪的原理或光强度调制的方法制成的。
