SPEAKER DEVICE AND ON-VEHICLE SPEAKER DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To provide a speaker device improving characteristics degradation due to division resonance and improving directional characteristics. SOLUTION: The speaker device is provided with a plurality of speaker units arrayed by turning the edge surface of a diaphragm in the same direction, at least two of the plurality of speaker units have the diaphragm whose center hole is eccentric, and orientations are in mutually different directions. The eccentricity of the center hole has direction components to be mutually opposite directions in a direction orthogonal to the array direction of the speaker units. The absolute values of the direction components to be the mutually opposite directions of the eccentricity of the center hole are equal. COPYRIGHT: (C)2006,JPO&NCIPI |
