Abstract
The present invention relates to speakers and, more particularly, to a speaker sound system, characterized in that the speaker, mounted on a speaker housing constituting a sound emission apparatus, has a guide cover to guide sound radiating from the back of the speaker forwards when the sound is output both forwards and backwards because of fluctuations of a cone of the speaker due to electrical signals, that is integrally attached to the surface of the speaker, thereby providing vivid high-fidelity sound.
