Slim enclosure speaker with side accoustic emission

The purpose of the present invention is to provide a slim enclosure speaker with a side acoustic emission structure capable of simultaneously improving an SPL feature and slimming the enclosure speaker with the side acoustic emission structure by maximizing a soundproof part in the same size. The present invention provides the slim enclosure speaker with the side acoustic emission structure which includes a microspeaker, a lower case which surrounds the lower side of the microspeaker and defines a resonance space, an upper case which includes a fixing surface to which the upper frame of the microspeaker is fixed, defines the resonance space with the lower case, and includes a hole on a pressing surface, a cover which is combined with the upper side of the upper case and covers the hole, and a sound path which is defined by the one side of the upper case and the cover. The fixing surface is inserted and molded with steel.
