Abstract
A musical instrument includes: an acoustic portion that makes sound in response to vibration; an exciter that includes an exciter body and a vibrating portion vibrating with respect to the exciter body, and excites the acoustic portion; and a support portion that is attached to the acoustic portion and supports the exciter body such that the vibration is transmitted from the vibrating portion to the acoustic portion. The support portion supports the exciter body such that the exciter body is elastically displaced with respect to the acoustic portion. A resonance frequency of a vibration system including the exciter body and the support portion is lower than the lowest resonance frequency of the acoustic portion.
