Abstract
A sound producing apparatus includes: a plurality of sound producing members with differing oscillation frequencies; dampers each corresponding to a respective sound producing member and suppressing vibration by contacting the corresponding sound producing members; a damper operation mechanism that moves each damper, thereby controlling a state of contact of the damper with a corresponding sound producing members; a soundboard that undergoes sympathetic resonance with sound producing members; a vibrator that vibrates the soundboard; an acquisition unit configured to acquire an audio signal; a signal output unit configured to: generate a drive signal for driving the vibrator with a vibration corresponding to the acquired audio signal; and output the drive signal to the vibrator; and a damper control unit configured to drive the damper operation mechanism to change a state of contact between the sound producing members and their corresponding dampers, based on frequency distribution of acquired audio signal.
