Abstract
A speaker assembly includes a speaker body and a resonating box. The speaker body formed by a main portion and a sound-emitting portion. The resonating box is provided within the speaker body. Both ends of the resonating box are connected to the main portion and the sound-emitting portion respectively. The resonating box is formed by connecting a plurality of resonating shells having decreasing widths. The resonating shells are made of rigid materials. Each of the resonating shells is slidingly connected with the adjacent resonating shells, so that the resonating shell is extendable between the main portion and the sound-emitting portion. Via this arrangement, in addition to amplify the music, the speaker assembly has a stress/bass effect to improve the quality of sound.
