PURPOSE: A built-in compact speaker system is provided, which can remove noise due to vibration of the speaker system itself effectively, and also prevent a sound quality from being decreased by preventing the vibration due to an electrical signal from a speaker unit from being exhausted to the outside. CONSTITUTION: A speaker unit(10) and an open aperture(21) are attached each other with a both-sides tape(14) having a cushion and at the same time a constant pushing force is applied toward the front by an elastic rib(33). Therefore, a soundproof structure and the attachment of the speaker unit is formed more perfectly. Also, a screw(40) is inserted into a boss(32) to make the fixing more perfectly, and a wire holder(13) is inserted into an insertion sill(34) to make the air flow or the propagation of vibration impossible.
