Abstract:
An electroacoustic transducer includes a piezoelectric speaker and a housing. The piezoelectric speaker has: a first vibration plate with a periphery; a piezoelectric element placed on at least one face of the first vibration plate; and multiple openings that are provided around the piezoelectric element and penetrate through the first vibration plate in its thickness direction that is a first axis direction. The housing has: a supporting part that directly or indirectly supports the periphery; and a sound introduction port that faces the piezoelectric speaker in the first axis direction. The sound introduction port is provided at a position where it does not overlap, in the first axis direction, a first opening having the largest open area among the multiple openings. The electroacoustic transducer can improve the acoustic characteristics of a piezoelectric speaker.

Claim (Index 1):
An electroacoustic transducer comprising:\n a piezoelectric speaker having:\n a first vibration plate with a periphery; and \n a piezoelectric element placed on at least one face of the first vibration plate, \n wherein multiple openings are provided around the piezoelectric element and penetrate through the first vibration plate as viewed in a thickness direction of the first vibration plate that is a first axis direction; and \n a housing having:\n a supporting part that supports the periphery of the first vibration plate; and \n a sound introduction port facing the piezoelectric speaker in the first axis direction, and provided at a position where the sound introduction port does not substantially overlap, as viewed in the first axis direction, a first opening having the largest open area among the multiple openings.
