Technical Examples
  1. The present invention intends to provide a piezo-electric speaker which can generate a sound from the low frequency range to the high frequency range as well as transmit the acoustic vibration to a sound-board with a high efficiency. This is achieved by providing a piezo-electric speaker comprising a piezo-electric member generating a strain according to an electric signal applied thereto; a piezo-electric vibration plate converting the strain to the acoustic vibration; and a sound-board resonating to the acoustic vibration; the piezo-electric plate being supported on the sound-board; the acoustic vibration caused by the piezo-electric vibration plate being propagated from the sound-board to the ambient air to generate a sound.
