ELECTROACOUSTIC TRANSDUCER

摘要

PROBLEM TO BE SOLVED: To provide an electroacoustic transducer employing a polyhedron diaphragm that can obtain an effective drive distribution and prevent the drive energy efficiency from being deteriorated. SOLUTION: In the electroacoustic transducer S employing the polyhedron diaphragm 10, holes 121-12n for extracting sound provided to an electrode 11 are placed just above the gravity center O of the polyhedron of the polyhedron diaphragm 10.
