Abstract

PURPOSE:To perform the extension of a low frequency range and the evenness of frequency characteristics economically and precisely by forming sound diffusing parts on the back of a cabinet and attaching speaker fitting members to the sound diffusing parts unitedly so as to project from the sound diffusing parts. CONSTITUTION:Sound diffusing parts 122L, 122R are formed so as not to make the parts corresponding to speakers on a back cabinet 12 parallel with the buffle surfaces of the speakers. Speaker holding members 121L, 121R are attached to the sound diffusing parts 122L, 122R unitedly so as to project from the sound diffusing parts in the inner-cabinet direction. Thus, bad influences due to reflected waves from the back of the cabinet to the speakers can be removed and oscillation can be suppressed. Moreover, the extension of the low frequency range and the evenness of frequency characteristics can be performed easily, economically and precisely only by changing the shape of the back of the cabinet.
