MICRO SPEAKER
First Claim
1. A micro speaker, comprising a vibration system, a magnetic circuit system and a support system for accommodating and fixing the vibration system and the magnetic circuit system, wherein the vibration system comprises a vibrating diaphragm and a voice coil bonded to one side of the vibrating diaphragm, and the vibrating diaphragm comprises a rigid dome portion located at a central position and a suspension ring portion located at an edge position;
- the magnetic circuit system comprises a washer, a magnet and a magnetic yoke which are sequentially combined together, and a magnetic gap for accommodating the voice coil is formed in the magnetic circuit system;
the support system comprises an upper housing; and
the upper housing is provided with a recessed groove structure at a position corresponding to the dome portion of the vibrating diaphragm, whereinthe dome portion is provided with a dodging groove at a position opposite to the groove structure of the upper housing;
a vertical depth of the dodging groove is not less than a depth of the groove structure of the upper housing; and
an orthographic projection area of the dodging groove covers an orthographic projection area of the groove structure of the upper housing;
the washer is provided with a dodging structure opposite to the dodging groove of the vibrating diaphragm;
a vertical depth of the dodging structure is not less than the depth of the dodging groove; and
an orthographic projection area of the dodging structure covers the orthographic projection area of the dodging groove of the vibrating diaphragm.
