Abstract
Aspects of the present disclosure provide an intentional leak from a rear volume of an ear cup to the atmosphere. The leak is created via a vent in the driver plate acoustic assembly. The vent reduces an acoustic load the ear cup cover creates on a rear cavity of an electroacoustic transducer contained within the driver plate acoustic assembly of a headset. Additionally, the vent is hidden on an assembled ear cup of a headset. Due to the placement of the vent, ear cup cover may have a smooth, seamless surface.
Claims16
A headset comprising a first ear cup connected by a headband to a second ear cup, the first ear cup comprising:
- a driver plate acoustic assembly comprising a vent, the driver plate acoustic assembly spanning the entire first ear cup;
- a front volume and a rear volume separated by the driver plate acoustic assembly;
- an ear cushion at least partially enclosing the front volume;
- an ear cup cover enclosing the rear volume;
- an electroacoustic transducer coupled to the driver plate assembly via a cover, wherein the cover encloses a rear cavity of the electroacoustic transducer;
- and
- a port acoustically coupling the rear cavity of the electroacoustic transducer to the rear volume, wherein
- the vent provides a path for air to flow from the rear volume to outside of the headset, the path extending from the vent through a gap between the ear cup cover and the ear cushion.
A headset comprising a first ear cup connected by a headband to a second ear cup, the first ear cup comprising:
- a driver plate acoustic assembly comprising a vent, the driver plate acoustic assembly spanning the entire first ear cup;
- an ear cup cover coupled to a first side of the driver plate acoustic assembly;
- an ear cushion coupled to a second side of the driver plate acoustic assembly;
- an electroacoustic transducer coupled to the driver plate assembly via a cover, wherein the cover encloses a rear cavity of the electroacoustic transducer;
- and
- a port acoustically coupling the rear cavity of the electroacoustic transducer to the first side of the driver plate acoustic assembly, wherein
- the vent is located in a gap between the ear cup cover, the driver plate acoustic assembly, and the ear cushion, and the vent provides a path for air to flow from a first side of the driver plate acoustic assembly to outside of the headset through the gap between the ear cup cover and the ear cushion.
