Abstract:
A speaker system which suppresses a standing wave without using a sound absorbing material and can reproduce clear, dynamic bass sound devoid of distortion and reverberation but having expansion. A casing (1) to which a speaker unit (3) is to be fitted comprises a front baffle (2), a back baffle (5) and side walls (4). A plurality of paper tubes closed at both ends are disposed inside the casing (1). A first paper tube (6a) extends from one end of the casing toward the other end in the longitudinal direction of the casing. Two second tubes (6b) are disposed inside the first tube, and the second tube has about 1/2 of the length of the first tube and about 1/2 of the cross section of the casing. Two third tubes (6c) are disposed in each second tube. The third tubes have about 1/2 of the length of the second tube and about 1/2 of the cross section of the second tube.
