ABSTRACT:
A compact lightweight speaker system without a resonance box that can reproduce the original sound with high fidelity. A speaker unit is located on a baffle board with a vibration absorbing member between a frame of the speaker unit and the baffle board. Furthermore, an acoustic resonance reflecting board of a vertical flat board type based on the operating principle of a passive radiator is formed by the baffle board and a flat board being similar to the baffle board. As a result, a compact smart design will be produced. It is applicable to an electric or electronic apparatus which produces sound.
