Abstract:
A multi-directional sound emission 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 plurality of hollow mechanical sound conducting elements. 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 of the sound conducting elements are directed towards desired multiple directions, respectively. The sound emission means is configured for receiving sound signals from the speaker body and emitting sound along the desired multiple directions through the sound conducting elements.
