PIEZOELECTRIC SPEAKER ARRANGEMENT

摘要

PROBLEM TO BE SOLVED: To provide a piezoelectric speaker arrangement which improves a high frequency region characteristics by applying the speaker arrangement to an on-vehicle door-mounted speaker and mounting the speaker on a lower portion of a door and is capable of satisfying thinning and lightening of an on-vehicle audio system. SOLUTION: The piezoelectric speaker arrangement is provided with first and second diaphragms which are mutually coupled and first and second piezoelectric elements which are mounted on the first diaphragm and the second diaphragm, and vibration directions of the first diaphragm and the second diaphragm are made non-parallel.
