Customizable headphone audio driver assembly, headphone including such an audio driver assembly, and related methods
View Patent ↗Headphones include removable audio drivers electrically coupled with electrical conductors using solderless and detachable interconnections. Driver assemblies for headphones include an audio driver and a driver unit housing. An acoustical cavity is defined between the driver unit housing and the audio driver, and a port extends through the driver unit housing between the acoustical cavity and the exterior of the driver assembly. The driver unit housing is configured to be secured within an outer ear-cup housing of a headphone such that the port is open to the exterior of the headphone without communicating acoustically with a volume outside the driver unit housing and within the outer ear-cup housing. Headphones include such driver assemblies. Methods are used to form such headphones and driver assemblies.
1. A headphone, comprising:
an outer ear-cup housing; and
a driver assembly located within the outer ear-cup housing, the driver assembly including:
a driver unit housing attached to the outer ear-cup housing, the driver unit housing defining an acoustical cavity within the driver unit housing, the driver unit housing including:
a port defined by the driver unit housing between the acoustical cavity and the exterior of the outer ear-cup housing without communicating acoustically with a volume of space inside the outer ear-cup housing and outside the driver unit housing; and
a cap located at a back side of the driver unit housing; and
an audio driver having terminals electrically coupled to electrical conductors configured to carry an electrical audio signal to the audio driver;
wherein the cap is coupled directly to the audio driver and disposed over a back side of the audio driver.
2. The headphone of claim 1 , wherein the cap is not a portion of an outer ear-cup housing of an ear-cup assembly of the headphone.
3. The headphone of claim 1 , wherein at least a portion of the outer ear-cup housing is at least partially transparent such that the cap is visible through the at least a portion of the ear-cup housing from an exterior of the outer ear-cup housing.
4. The headphone of claim 3 , wherein the cap has at least one aesthetic decoration thereon.
5. The headphone of claim 1 , wherein the cap has at least one aesthetic decoration thereon.
6. The headphone of claim 1 , wherein the cap is adjustable, adjustment of the cap causing adjustment of a detectable sound pressure level (SPL) profile of the headphone.
7. The headphone of claim 6 , wherein the cap comprises a port configured to be opened or closed.
8. The headphone of claim 6 , wherein the cap comprises a port having an adjustable cross-sectional area.
9. The headphone of claim 8 , wherein the cross-sectional area of the port is adjustable by rotating the cap relative to the audio driver.
10. The headphone of claim 1 , wherein the audio driver is removable from the headphone without causing damage to any component of the headphone.
11. The headphone of claim 10 , wherein the terminals of the audio driver are coupled to the electrical conductors with a solderless and detachable electrical coupling.
12. The headphone of claim 11 , wherein the solderless and detachable electrical coupling comprises a plug-and-receptacle coupling.
13. The headphone of claim 11 , wherein the solderless and detachable electrical coupling comprises a spring contact.
14. The headphone of claim 11 , wherein the solderless and detachable electrical coupling comprises a magnetic coupling.
