Title: THIN TYPE SPEAKER
Abstract:
The present invention relates to a slim type speaker. The slim type speaker, in which vibrating spaces of a diaphragm and a voice coil are separated, is not affected by the height (thickness) of a magnetic circuit, and thus can reduce the thickness thereof, and comprises: a diaphragm (40) having a predetermined vibrating plane; a connecting portion (36) extending in a direction deviating from a vibrating plane on the diaphragm; a voice coil (26) fixed to an end of the connecting portion and arranged at a position deviating from the vibrating plane; and a magnetic circuit (20) having the voice coil embedded therein, wherein a cut portion (241) is arranged on the magnetic circuit portion intersecting the connecting portion and provides a space allowing the connecting portion to move in response to a vibrating direction of the diaphragm. The magnetic circuit (20) may be arranged on a center-hole portion arranged in the center of the diaphragm or on an outer circumference of the diaphragm.
