Abstract
Embodiments are provided for configurations of a loudspeaker and assembly of the loudspeaker. The loudspeaker may include a frame, a voice coil, a magnetic structure that includes a magnetic gap, a surround, a spider, and a circumferential spacer element. The circumferential spacer element may include a first tier attached to an outer rim of the surround; and a second tier attached to an outer rim of the spider, wherein the circumferential spacer element is coupled to the frame such that the voice coil is suspended at least partially within the magnetic gap.
Claims20
A loudspeaker comprising:
- a frame;
- a voice coil;
- a magnetic structure comprising a magnetic gap;
- a surround;
- a spider;
- and
- a circumferential spacer element comprising:
- a first tier attached to an outer rim of the surround;
- and
- a second tier attached to an outer rim of the spider, wherein the circumferential spacer element is coupled to the frame such that the voice coil is suspended at least partially within the magnetic gap.
A circumferential spacer element of a loudspeaker, comprising:
- a first tier attached to an outer rim of a surround, wherein an inner rim of the surround is attached to an outer rim of a diaphragm, and wherein a central portion of the diaphragm is coupled to a voice coil;
- and
- a second tier attached to an outer rim of a spider, wherein an inner rim of the spider is attached to a lower surface of the diaphragm, and wherein the circumferential spacer element has a structural shape configured to be coupled to a frame of the loudspeaker such that the voice coil is suspended at least partially within a magnetic gap of a magnetic structure of the loudspeaker.
A method for assembling a loudspeaker, the method comprising:
- (a) providing a first sub-assembly comprising:
- a voice coil;
- a surround;
- a spider;
- and
- a circumferential spacer element comprising:
- an first tier attached to an outer rim of the surround;
- and
- a second tier attached to an outer rim of the spider;
- (b) providing a second sub-assembly comprising:
- a loudspeaker frame;
- and
- a magnetic structure coupled to a central portion of the loudspeaker frame;
- and
- (c) coupling the circumferential spacer element of the first sub-assembly with the loudspeaker frame of the second sub-assembly such that the voice coil of the first sub-assembly is suspended at least partially within a magnetic gap of the magnetic structure of the second sub-assembly.
