のスピーカーシステム。[Claims for Utility Model Registration] 1. At least one speaker is disposed on the front plate of a speaker box with its radiation axis facing forward, and at least one speaker is arranged on an inclined plate formed at an obtuse angle on the top plate and rear plate of the speaker box, respectively. One compensation speaker is arranged so that its radiation axis faces at least backward and upward. The frequency band of the compensation speaker is (0.5~1.0
) A speaker system characterized by inputting a selected signal having a value of c/2r a or more (where C: speed of sound, a: effective vibration radius of a speaker placed on a front panel). 2 At least a bass speaker and a treble speaker are arranged on the front plate of the speaker box with their radiation axes facing forward, and at least a first
The compensation speaker and the second compensation speaker are arranged such that their radiation axes face at least rearward and upward, and the reproduction frequency band of the first compensation speaker is (
0,5~1.0) c/2wat to fc, the reproduction frequency band of the second compensation speaker is (0,5~1.o)
c/2waz or more (C: speed of sound, a□: effective vibration radius of bass speaker, a2: effective vibration radius of treble speaker, fcH crossover frequency between bass speaker and treble speaker). A speaker system according to claim 1 of the utility model registration claim. 3. Claim 2 of the registered utility model, characterized in that at least one compensation speaker is arranged on a wedge-shaped base fixed to the inclined plate and whose thickness decreases toward the side of the box. The speaker system described in section. 4. Utility model registration claim 2, characterized in that a reflecting plate is disposed on the radiation axis of the compensation speaker, and the reflecting plate is rotatably attached to the speaker box.
The speaker system described in section. 5. The speaker system according to claim 2, wherein the speaker box has a substantially cubic shape with its top plate and side plate extended. 6. The speaker system according to claim 5, characterized in that the top plate and/or the side plate is provided with a slit that communicates with the space formed by the top plate, the side plate, and the inclined plate.
