載の圧電イヤホーン。[Claims for Utility Model Registration] (1) A piezoelectric sounding body is supported at its outer periphery inside an exterior case in which a cylindrical sound guiding part projects outward, and the piezoelectric sounding body generates sound. In a piezoelectric earphone in which sound waves are guided to the outside through the sound guiding portion, the piezoelectric sounding body is bonded to the inner circumference of a ring-shaped foam provided with an adhesive layer, and the outer circumference of the foam is bonded to the inner circumference of the ring-shaped foam provided with an adhesive layer. A piezoelectric earphone characterized in that a portion of the earphone is bonded to an inner wall surface of the outer case, and the foam body supports the piezoelectric sounding body on the outer periphery of the outer case. (2) The piezoelectric earphone according to claim 1, wherein a continuous foam body through which air can pass is inserted into the sound guiding portion.
