Claims

[Scope of Claim for Utility Model Registration] (1) A speaker device in which a plurality of high-pitched and low-pitched speakers are arranged in a car, with the high-pitched speaker placed above and in front of the passenger; A vehicle-mounted speaker device characterized in that the direction of the speaker is directed from the front of the vehicle to the rear and downward. (2) The directional characteristic of the high-pitched speaker is a narrow directional characteristic, and the extended direction of the directional characteristic is directed toward the passenger's head, and the direction behind the head is directed toward the lower part of the car where the sound absorption coefficient is high. A vehicle-mounted speaker device according to claim 1, which has been registered as a utility model. (3) The vehicle-mounted speaker device according to claim 1 or 2, wherein the central extension direction of the directional direction of the high-pitched speaker is directed below the window glass. (4) The high-pitched speaker is installed in such a way that a part of the sub-radiated waves is reflected by the window glass and becomes a reflected wave, and the extension of the reflected wave is directed toward the lower part of the vehicle without reaching the passenger's head. An in-vehicle speaker device according to claim 1 or 2 of the utility model registration claim in which the position is selected.
