Abstract
A speaker frame, and corresponding speaker, may have tapered spokes that form a radial triangular pattern with an apex converging near the frame's mounting flange, for example, near tabs including mounting holes where the frame attaches to a speaker baffle. The tapered spokes may include a triangular cut-out region defining a pair of converging legs that converge at the mounting flange. The width, curvature, and the angle of the spokes may allow for a thin and lightweight configuration with uniformly distributed minimal stress.
Claims20
A frame for a speaker comprising:
- a base including a mounting surface for mechanically coupling to a motor assembly of the speaker;
- a mounting flange configured to mount the speaker to a baffle and support a diaphragm assembly;
- and
- a plurality of tapered spokes extending from the base to support the mounting flange, each tapered spoke tapering from the base in a direction of the mounting flange.
A speaker comprising:
- a diaphragm assembly including a diaphragm and a surround;
- a motor assembly for driving the diaphragm assembly;
- and
- a frame having a base mechanically coupled to the motor assembly, a mounting flange coupled to the diaphragm via the surround, and a connecting structure extending between the base and the mounting flange, the connecting structure including a plurality of tapered spokes extending from the base and tapering in a direction of the mounting flange.
A loudspeaker assembly comprising:
- a baffle;
- and
- at least one speaker mounted to the baffle, each speaker including:
- a diaphragm assembly including a diaphragm and a surround;
- a motor assembly for driving the diaphragm assembly;
- and
- a frame having a base mechanically coupled to the motor assembly, a mounting flange coupled to the diaphragm via the surround, and a connecting structure extending between the base and the mounting flange;
- wherein the connecting structure includes a plurality of tapered spokes extending from the base and tapering in a direction of the mounting flange to form a radial triangular pattern having an apex adjacent the mounting flange.
