Abstract:
A micro-speaker is disclosed. The micro-speaker includes a frame with a hollow space, a diaphragm attached to the frame, a voice coil with a lead, a yoke received in the hollow space, a magnet received in the yoke. The yoke includes a base wall in shape of rectangle with two long boundaries and two short boundaries. The base wall includes a first portion locating at the middle of the base wall and two second portions locating at two ends of the first portion and extending to the two short boundaries respectively. The first portion has a thickness greater than the second portion. The second portion of the base wall provides an extra space for at least part of the lead so as to avoid the lead bumping against the base wall.

Claim (Index 1):
A micro-speaker, comprising:\n a frame forming a hollow space by a plurality of inner sidewalls; a diaphragm attached to the inner sidewalls; a pair of conductive terminals attached to the frame; a yoke received in the hollow space, the yoke comprising a base wall in shape of rectangle with two long boundaries corresponding to each other and two short boundaries corresponding to each other, and only two sidewalls extending upwardly and perpendicularly from the two long boundaries of the base wall respectively; a magnet received in the yoke; a voice coil activating the diaphragm; wherein the base wall comprises two portions located between the two sidewalls of the yoke, where a first portion locates at the middle of the base wall and two second portions locate at two ends of the first portion and extending to the two short boundaries respectively, a thickness of the first portion is greater than that of the second portion, the base wall further comprises a slope connecting the first portion and the second portion, the magnet is installed on the first portion and forms a magnetic gap together with the two sidewalls of the yoke, the voice coil comprises two leads extending from the lower end of the voice coil far away from the diaphragm, the second portion of the base wall provides an extra space for at least part of the lead so as to avoid the lead bumping against the base wall.
