Document Type and Number:
Japanese Patent JP2016082321
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electroacoustic transducer capable of controlling directional characteristics in a characteristic direction only by a speaker unit without inclining a mounting surface of a speaker and also mounting a retrofitted component on a speaker unit.SOLUTION: An electroacoustic transducer includes: a vibrator 1; a transduction part 2 which performs a conversion between vibration of the vibrator 1 and an electric signal corresponding to the vibrator; and a support part 3 which movably supports the vibrator 1 along the vibration direction. The vibrator 1 has three pairs of protruded surfaces 5 of a pair of vertically split cylinder parts. In each pair, a trough 6 is formed by one side parts of the protruded surfaces 5, and respective troughs 6 are radially arranged.SELECTED DRAWING: Figure 1
