Abstract

PURPOSE:To widen a low frequency range and to flatten frequency characteristics easily, economically and precisely by forming a sound diffusing part on the back of a cabinet in one body with the cabinet. 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 and so as to be united with the cabinet 12. 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 number of parts and the number of assembling works are reduced and the low frequency range is widened and the frequency characteristic easily, economically and precisely only by changing the shape of the back of the cabinet.
