Abstract
Headphone playback devices can include a cable assembly including a plurality of conductors extending between a first earpiece and a second earpiece. The cable assembly includes a jacket, a power conductor disposed within the jacket and coupled between a power source in the first earpiece and a wireless transceiver in the second earpiece. The cable assembly further includes a microphone conductor at least partially disposed within the jacket and coupled to a microphone in one of the earpieces. A shield is at least partially disposed between the power conductor and the microphone conductor to reduce electromagnetic interference between the two.
Claims20
A headphone device comprising:
- a first earpiece;
- a second earpiece;
- at least one microphone at least partially disposed in at least one of the first earpiece or the second earpiece;
- a wireless transceiver at least partially disposed in the first earpiece;
- a power source at least partially disposed in the second earpiece;
- a cable assembly extending between the first earpiece and the second earpiece, the cable assembly comprising:
- a jacket;
- one or more power conductors at least partially disposed within the jacket and coupled between the power source and the wireless transceiver;
- one or more microphone conductors at least partially disposed within the jacket and coupled to the at least one microphone;
- and
- a shield at least partially disposed between the one or more power conductors and the one or more microphone conductors.
A wearable device comprising:
- a housing configured to be worn about a head of a subject;
- a power source at least partially disposed in the housing and disposed on a first side of the subject when the wearable device is worn about the head;
- at least one analog sensor at least partially disposed in the housing;
- a wireless radio at least partially disposed in the housing and disposed on a second, opposite side of the subject when the wearable device is worn about the head;
- a cable assembly at least partially disposed in the housing and comprising:
- one or more power conductors coupled between the power source and the wireless radio;
- one or more sensor conductors coupled to the at least one analog sensor;
- and
- a shield at least partially separating the one or more power conductors from the one or more sensor conductors, wherein the shield comprises one or more conductors helically extending around at least one of the one or more power conductors.
A cable assembly for a headphone device including a first earpiece and a second earpiece, the cable assembly comprising:
- a jacket having an outer diameter between 4 millimeters (mm) and 6 mm;
- an inner coaxial cable at least partially disposed within the jacket, wherein the inner coaxial cable comprises a first end configured to electrically couple to an antenna at least partially disposed in the second earpiece and a second end configured to electrically couple to a wireless transceiver at least partially disposed in the first earpiece;
- one or more power conductors at least partially disposed within the jacket, wherein the one or more power conductors comprises a first end configured to electrically couple to a battery at least partially disposed in the second earpiece and a second end configured to couple to the wireless transceiver at least partially disposed in the first earpiece;
- one or more microphone conductors at least partially disposed within the jacket, wherein the one or more microphone conductors includes a first end configured to couple to electrically couple to at least one microphone;
- and
- a shield at least partially disposed between the one or more power conductors and the one or more microphone conductors, wherein the shield comprises one or more conductors helically extending around at least one of the one or more power conductors.
