Patent ID: 7878296

Claim:
A speaker realizing high-fidelity sound, in which a vibration plate, a damper and a lead wire are sequentially placed in the front thereof, having a connection part connected to the vibration coil and to an external terminal, formed in an outer circumferential end of a frame, the speaker ( 1 ) comprising: a frame ( 5 ) enclosing the vibration plate with an interval defined between the frame and the vibration plate, in the center of which a vibration coil, a yoke, and a magnet are provided; a cover ( 2 ) having an opening part and attached to a center of an outer circumference of the frame enclosing the vibration plate, with an interval defined between the frame and the cover, guiding and reflecting rearwardly transmitted sound generated behind the vibration plate forwardly through the opening part, thereby outputting the rearwardly transmitted sound simultaneously with forwardly transmitted sound generated in the front of the vibration plate, wherein the cover encloses the back of the vibration plate, wherein the vibration coil, the yoke, and the magnet are disposed outside the cover, and wherein the cover is hemispherical; and a plurality of through holes ( 7 ) formed on the frame, such that air circulates to back of the vibration plate and the rewardly transmitted sound is guided to the cover to be reflected forwardly through the opening part ( 3 ) of the cover.
