摘要： PROBLEM TO BE SOLVED: To provide a speaker surround structure for maximizing the cone diameter.SOLUTION: In a compact speaker, to enable the deployment of a diaphragm (14) of larger diameter than is used conventionally for the corresponding basket (10) size, the outer basket-attachment portion of a surround-suspension (12) is made in a special configuration shaped as an axial skirt (16a). A speaker basket (10) of the present invention is made with a corresponding axial peripheral flange of which the inner wall is made to serve as a landing (20) for adhesive attachment to the outer wall of the axial surround suspension flange. This special configuration retains the required resilience and capability of full excursion while enabling enlargement of the effective vibrating piston area substantially by deployment of a larger cone.

摘要： PROBLEM TO BE SOLVED: To improve a sound pressure level and sound quality of a piezoelectric electroacoustic transducer without impairing its size, its productivity, its cost etc.
SOLUTION: The piezoelectric electroacoustic transducer 1 is provided with: a frame 20; a piezoelectric resonator 10 formed by joining piezoelectric elements 12, 13 on a metal plate 11; and a supporting member 30 consisting of a ring-like resin film made of PET resin and supporting a peripheral portion of the piezoelectric resonator 10 on the frame 20. A mesh-like unevenness or a crimped unevenness is formed on the surface of the supporting member 30 to give the supporting member 30 flexibility for preventing interference on large displacement of the piezoelectric resonator 10 while the external shape of the supporting member 30 is kept as it is.
