PROBLEM TO BE SOLVED: To utilize a handle attached to an acoustic system as a bass reflex port. SOLUTION: In this acoustic system having a main body part provided with at least speakers and a handle part attached to the main body part, an internal space is formed in the handle part and holes for releasing sound are also formed in required parts. Moreover, the internal space of the handle part communicates with spaces in the back faces of the speakers, formed in the main body part. This can output sound pressure of the back faces of the speakers from the holes for releasing sound provided in the handle part in a prescribed phase state, thereby obtaining a bass reflex effect using the handle part.
