Abstract
A slim enclosure speaker is provided with a side acoustic emission structure, which can make the enclosure speaker slimmer by maximizing a sound-emitting hole in the same size, while improving SPL characteristics. The slim enclosure speaker with the side acoustic emission structure includes: a microspeaker; a lower case enclosing the lower side of the microspeaker and defining a resonance space; an upper case having a fixing surface to which top edges of the microspeaker are fixed, defining the resonance space together with the lower case, and having a hole inside the fixing surface; a cover coupled onto the upper case and covering the hole; and an acoustic passage defined by one side of the upper case and the cover, wherein the fixing surface is insert injection-molded using a steel.
