OSCILLATION DEVICE AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an oscillation device capable of an output in large volume even with a small occupied area.

SOLUTION: An electroacoustic transducer 100 is structured so that a plurality of piezoelectric vibrators 110 each being perfectly circular or hexagonal in planar shape are positioned in a zigzag arrangement to ensure closet packing in planar shape. Thus, because the occupied area of the plurality of piezoelectric vibrators 110 is minimized, a small and highly efficient parametric speaker can be achieved.
