Abstract
A speaker in which an end of a magnetic assembly close to the diaphragm has a magnetic gap. A coil is wound around a coil former, and at least a portion of the coil is located in the magnetic gap. A connecting member is arranged on a side of the coil former close to a side wall of the accommodating cavity. An annular first damper is arranged between the coil former and the connecting member. The first damper is close to an upper end of the coil and is distal from a lower end of the coil. An annular second damper is arranged between the connecting member and the side wall of the accommodating cavity. The second damper is close to the lower end of the coil and is distal from the upper end of the coil.
Claims20
A speaker, comprising:
- a frame comprising a concave accommodating cavity, wherein the concave accommodating cavity comprises:
- an opening;
- a first bottom;
- and
- a first side wall;
- a diaphragm configured to cover the opening and coupled to the frame;
- a magnetic assembly, wherein a first part of the magnetic assembly is arranged in the concave accommodating cavity and is coupled to the first bottom, and wherein of the magnetic assembly comprises a first end that is proximate to the diaphragm and that has a magnetic gap;
- a vibrating assembly located in the concave accommodating cavity, coupled to the diaphragm, and comprising:
- a coil former comprising a first side proximate to the first side wall;
- a coil wound around the coil former, wherein a portion of the coil is located in the magnetic gap, and wherein the coil comprises:
- an upper end proximate to the diaphragm;
- and
- a lower end distal from the diaphragm;
- and
- a connecting member arranged on the first side;
- an annular first damper proximate to the upper end, distal from the lower end, located in the concave accommodating cavity and between the coil former and the connecting member, and comprising:
- a first inner side coupled to the magnetic assembly;
- and
- a first outer side coupled to the connecting member to support the vibrating assembly in a first radial direction of the annular first damper;
- and
- an annular second damper proximate to the lower end, distal from the upper end, located in the concave accommodating cavity and between the connecting member and the first side wall, and comprising:
- a second inner side coupled to the connecting member;
- and
- a second outer side coupled to the first side wall to support the vibrating assembly in a second radial direction of the annular second damper.

- and
- an annular second damper proximate to the lower end, distal from the upper end, located in the concave accommodating cavity between the connecting member and the first side wall, and comprising:
- a second inner side coupled to the connecting member;
- and
- a second outer side coupled to the first side wall to support the vibrating assembly in a second radial direction of the annular second damper;
- and
- a housing comprising a mounting hole,
- wherein a third part of the speaker is located in the mounting hole.
