Speaker assembly
First Claim
1. A speaker assembly, comprising:
- a speaker enclosure forming a back volume chamber and having walls defining a vent opening;
a speaker unit; and
a layer of mesh material extending across the vent opening, the layer of mesh material including a first region and a second region, the first region being closer to the walls defining the vent opening than the second region,wherein the vent opening is configured to allow passage of pressure waves generated by the speaker unit to exit the speaker enclosure and wherein the first region has a first acoustic resistance and the second region has a second acoustic resistance different than the first acoustic resistance.

Abstract
Examples of speaker assemblies are described. A speaker assembly according to some embodiments may include a speaker enclosure with a first opening (e.g., a speaker opening) and a second opening (e.g. a bass reflex port), a speaker unit mounted to the enclosure at the first opening, and an acoustic damping mechanism mounted to the enclosure at the second opening. The acoustic damping mechanism may be a dual-layer mesh screen including a first mesh with a first acoustic resistance (AR) for providing acoustic damping, and a second mesh with a second AR lower than the first AR. The second mesh may be nearly acoustically transparent and may serve to increase the stiffness of the first mesh. The first mesh may be bonded to the second mesh, and the dual-layer mesh screen may be coupled to the bass reflex port for reducing noise associated with turbulence at the port.

9. A damping mechanism configured to cover an opening defined by walls of a speaker enclosure, comprising:
-
a layer of mesh material extending across the opening, comprising; a first mesh region corresponding to a central portion of the layer of mesh material and having a first acoustic resistance; and a second mesh region corresponding to a perimeter portion of the mesh screen at least partially surrounding the first mesh region and having a second acoustic resistance that is different than the first acoustic resistance, wherein the second mesh region is closer to the walls defining the opening than the first mesh region. - View Dependent Claims (10, 11, 12, 13, 14)
