电声器件利用声量子传播,即利用与材料的晶体点降结构有关振荡作为能量传递机构。金属换能器利用材料的压电特性把电能转换为声能。绝大
Electroacoustic devices use the sound quantum transmission, that is, the use of material and the crystal structure of the point drop oscillation as the energy transfer mechanism. Metal transducers use the piezoelectric properties of materials to convert electrical energy to acoustic energy. Great
