Abstract:
A multi-directional sound emission means and a system having same are disclosed. The system comprises a speaker body and sound emission devices coupled to both ends of the speaker body. The sound emission devices each include a sound emission means for directionally emitting sound towards multiple directions. The sound emission means includes a base, a loudspeaker disposed on the base, and a plurality of hollow mechanical sound conducting elements. The loudspeaker has an opening where the sound is emitted. Each hollow mechanical sound conducting element has an inner opening end and an exterior opening end opposite to the inner opening end. The exterior opening ends are directed towards desired multiple directions, respectively. The inner opening ends are in sound communication with the opening of the loudspeaker such that sound from the loudspeaker is emitted along the desired multiple directions through the sound conducting elements.
