Abstract
A damping system for an ear cup headphone design. The damping system introduces a completely enclosed inner acoustic volume in the rear volume of the ear cup by way of supporting a baffle damper spaced apart from the driver of the ear cup, wherein the density of the baffle damper diffuses acoustic wave rearwardly emanating from the driver. Additional damper masses of different relative densities may occupy the rear volume rearward of baffle damper.
Claims16
A damping system for a rear volume of an ear cup, the system comprising:
- a driver;
- a housing, in conjunction with the driver, defining the rear volume;
- a baffle damper disposed rearward of the driver in such a way as to define an enclosed inner acoustic volume, and wherein the baffle damper is spaced apart forward of a rear portion of the housing,
- wherein the baffle damper is spaced apart from the driver by a maintain distance having a range between one and ten millimeters;
- and
- a first damper mass spaced apart forward from the rear portion of the housing, wherein the first damper mass is spaced apart rearward of the baffle damper.

A damping system for a rear volume of an open-back ear cup, the system comprising:
- a driver;
- an open-back housing circumscribing the driver;
- a baffle mass disposed rearward of the driver in such a way as to define an enclosed inner acoustic volume, wherein the baffle mass has a Pores Per Inch (PPI) density of less than 100, wherein the baffle mass is spaced apart from the driver by a maintain distance having a range between one and ten millimeters;
- a baffle holder engaging both a driver holder of the driver and the baffle mass, and wherein the driver holder circumscribes the enclosed inner acoustic volume, wherein the baffle mass has a dome-like shape that defines a rear portion of the enclosed inner acoustic volume, and wherein the baffle mass has a first damper mass and a second damper mass spaced apart from the first damper mass in such a way as to define a second enclosed inner acoustic volume therebetween.
