Abstract
A transducer assembly including a frame, a diaphragm positioned within the frame, a surround connecting the diaphragm to the frame, the surround having a corner section and a plurality of corrugations formed within the corner section, wherein each corrugation of the plurality of corrugations comprises a length dimension perpendicular to a line of maximum stress intersecting a radial axis of the corner section, a voice coil extending from one side of the diaphragm and a magnet assembly having a magnetic gap aligned with the voice coil.
Claims18
A transducer assembly comprising:
- a frame;
- a diaphragm positioned within the frame;
- a surround connecting the diaphragm to the frame, the surround having a corner section and a series of alternating ribs and furrows within the corner section, wherein the series of alternating ribs and furrows have a same continuous shape, and wherein each of the ribs or furrows comprises a length dimension perpendicular to a line of maximum stress intersecting a radial axis of the corner section;
- a voice coil extending from one side of the diaphragm;
- and
- a magnet assembly having a magnetic gap aligned with the voice coil.
A surround for suspending a transducer diaphragm, the surround comprising:
- a first membrane section having a length dimension parallel to a first axis;
- a second membrane section having a length dimension parallel to a second axis;
- a corner membrane section at an intersection between the first axis of the first membrane section and the second axis of the second membrane section, wherein the first axis and the second axis intersect to form a ninety degree angle and the corner membrane section comprises an arcuate inner edge;
- and
- a plurality of continuous corrugations within the corner membrane section, wherein the plurality of continuous corrugations comprise a series of alternating ribs and furrows having a same continuous shape, and each corrugation of the plurality of continuous corrugations comprises a length dimension perpendicular to a line tangential to the arcuate inner edge of the corner membrane section.
A micro-speaker surround comprising:
- a membrane for connecting a diaphragm to an enclosure, the membrane having a first pair of parallel side sections, a second pair of parallel side sections, and a set of corner sections connecting the first pair of parallel side sections and the second pair of parallel sides sections;
- and
- a plurality of continuous corrugations within each corner section of the set of corner sections, and wherein each of the corrugations of the plurality of continuous corrugations within each corner section have a length dimension perpendicular to a line of maximum stress intersecting a radial axis of their respective corner section and parallel to the radial axis.
