Abstract:
PROBLEM TO BE SOLVED: To provide an acoustic piano which generates sound of relatively loud volume by driving a housing at the time of sound generation.SOLUTION: Vibration units TR2, TR3, TR5 and TR1 are installed at a vibration object upper front plate 12-1, a lower front plate 12-2, a keyboard lid 35 and a roof front 16, respectively which are at least a part of a housing 11. A signal output unit generates a drive signal for driving the vibration units on the basis of a detection signal detected by a key sensor S1 or a hammer sensor S2 through operation with respect to a key 41 and then outputs the drive signal to the vibration units. The vibration object vibrates, so that loud sound is generated without requiring a sound board.SELECTED DRAWING: Figure 1
