Abstract
A wireless headset with a headband that is constructed and arranged to fit over a user's head. The headband includes an antenna that is adapted to transmit and receive wireless signals, and electronic signal processing hardware that is electrically matched to the antenna. The headset also includes earcups carried by the headband, each earcup arranged to sit on, over or near one ear of the user. Each earcup has an audio transducer.
Claims20
A wireless headset, comprising:
- first and second earcups, each earcup arranged to sit on, over or near one ear of the user, each earcup comprising an audio transducer;
- and
- a headband that is constructed and arranged to fit over a user's head, wherein the headband comprises an elongated, curved, metal support structure that is mechanically coupled to the earcups, and an antenna that comprises an opening directly in the metal support structure, where the antenna is adapted to transmit and receive wireless signals, and electronic signal processing hardware that is electrically matched to the antenna.
A wireless headset, comprising:
- first and second earcups, each earcup arranged to sit on, over or near one ear of the user, each earcup comprising an audio transducer;
- and
- a headband that is constructed and arranged to fit over a user's head, wherein the headband comprises:
- a metal support structure that is mechanically coupled to the earcups, and an antenna that is an integral part of the metal support structure and is adapted to transmit and receive wireless signals, wherein the antenna comprises an opening directly in the metal support structure, and has a radiation efficiency, defined as total radiated power divided by total input power when measured on a body or a proxy, and wherein the radiation efficiency of the antenna is greater than 50%;
- and
- electronic signal processing hardware that is electrically matched to the antenna.

A wireless headset, comprising:
- a headband that is constructed and arranged to fit over a user's head, wherein the headband comprises:
- a generally flat metal support structure that generally follows a curve of the headband, and a slotted loop antenna that is an integral part of the metal support structure and comprises a loop-shaped opening directly in the metal support structure and a slot in the metal support structure that is connected to the opening, where the antenna is adapted to transmit and receive wireless signals and has a radiation efficiency, defined as total radiated power divided by total input power when measured on a body or a proxy, of greater than 50%;
- and
- electronic signal processing hardware that is carried by a printed circuit board that is electrically coupled to the metal support structure proximate the slot;
- and
- first and second earcups carried by the headband and mechanically coupled to the metal support structure, each earcup arranged to sit on, over or near one ear of the user, each earcup comprising an audio transducer;
- wherein the metal support structure extends for most of a distance between the first and second earcups.
