Condenser microphone capsule backplate
An assembly for a condenser microphone capsule, the assembly comprising: a plate having opposing planar surfaces and one or more tabs extending laterally from a peripheral region, at least one tab being adapted to receive an electrical connector; and a mount affixed around at least a portion of the peripheral region.
1. An assembly for a condenser microphone capsule, the assembly comprising:
a plate having opposing planar surfaces and defining a central axis and peripheral region extending thereabout, the plate comprising one or more tabs projecting laterally away from the peripheral region and away from the central axis, wherein at least one of the one or more tabs comprises as aperture extending radially therein relative to the central axis, the aperture adapted to engage an electrical connector and provide an electrical connection between the electrical connector and the plate; and
a mount for mounting the assembly to the condenser microphone capsule, the mount abutting and wrapping around the peripheral region and the one or more tabs, thereby enclosing a periphery of the plate and defining an annular surface surrounding the plate and arranged parallel to the planar surfaces, the mount formed from an electrical insulator thereby insulating the plate from the condenser microphone capsule.
2. The assembly according to claim 1 , wherein the mount has a recess extending therein proximal to the aperture and dimensioned to allow the electrical connector to engage the aperture.
3. The assembly according to claim 2 , wherein the plate comprises a plurality of the tabs and the mount abuts and encloses the peripheral region and each of the plurality of tabs.
4. The assembly according to claim 3 , wherein the plurality of tabs are equidistantly spaced around the peripheral region.
5. The assembly according to claim 4 , wherein the plate has four tabs.
6. The assembly according to claim 1 , wherein the mount defines a sidewall extending around a periphery thereof, and each of the one or more tabs has an end face arranged substantially parallel to and spaced apart from the sidewall, within the periphery of the mount, and wherein the recess extends through the sidewall and at least up to one of the end faces.
7. The assembly according to claim 6 , wherein the aperture is arranged proximal to the recess and extends into the respective end face, thereby allowing the electrical connector to be engaged therein.
