  • Design method of Piezoceramic Discs or Plates: Generally speaking, the audio frequency range that the human ear can hear is about 20Hz to 20kHz. The audio frequencies most easily heard by humans are between 2kHz and 4kHz. Therefore, most piezoelectric sound-emitting elements are used in this audio frequency range. At the same time, the resonant frequency is generally selected within the same range. The resonance frequency depends on the method used to support the piezoelectric vibrating plate. Typically, piezoelectric vibrating plates are installed in resonant chambers to generate high sound pressures. This is the design method of FBelec, welcome to consult our engineer to get more information.
