MUSICAL INSTRUMENT CAPABLE OF PRODUCING ADDITIONAL VIBRATION SOUND AND METHOD THEREFOR

The musical instrument of the invention includes: a pickup (11) that acquires an electric sound signal corresponding to a sound performed on the musical instrument; an effector unit (12) that imparts an effect to the acquired electric sound signal; a vibrator (14) that produces mechanical vibration corresponding to the effect-imparted sound signal; and a transmission device that transmits the mechanical vibration, produced by the vibrator, to the body of the musical instrument with a characteristic having a fundamental frequency region of the musical instrument suppressed. The electric sound signal corresponding to the performed sound is imparted with an effect, the vibrator is driven by the effect-imparted sound signal, and a mechanical vibration sound is generated from the body of the musical instrument. The thus-generated mechanical vibration sound is audibly generated from the body as a vibration sound additional to the performed sound, which allows a user to experience a performance feeling that has never existed before. Further, because the mechanical vibration produced by the vibrator is transmitted to the body of the musical instrument with the characteristic having the fundamental frequency region of the musical instrument suppressed, it is possible to suppress howling occurring due to the feedback of the performed sound of the instrument.
