ABSTRACT:
The acoustic apparatus for generating a musical tone preferably adopts a speaker system utilizing a resonator constituted by a cavity and an acoustic mass for causing the cavity to acoustically communicate with an external region or a speaker system utilizing a back-loaded horn so that frequency characteristic is improved. In a musical instrument, including a resonator, like a guitar, all or part of a body is partitioned as the cavity, and acoustic mass such as a resonance port is disposed in the cavity as needed to set a desired resonance frequency. In a musical instrument having side plates or leg portions, the resonance port or the back-loaded horn is housed in the side plates or the leg portions.
