Abstract
Systems and methods for a wireless stereo headset are disclosed. The system generally includes a first headset component and a second headset component. Both the first headset component and the second headset component may be wireless devices.
Claims20
A stereo headset system comprising:
- a first wireless component comprising:
- a first speaker;
- a microphone;
- a first wireless communication module;
- a first wireless component housing;
- a second wireless communication module comprising a magnetic induction transmitter, the magnetic induction transmitter comprising a transmit loop aerial disposed within the first wireless component housing at a first orientation;
- and
- a second wireless component comprising:
- a second wireless component housing;
- a second speaker;
- and
- a third wireless communication module comprising a magnetic induction receiver for receiving an audio signal from the second wireless communication module during stereo mode operation, the magnetic induction receiver comprising a receive loop aerial disposed within the second wireless component housing at a second orientation matching the first orientation, wherein the transmit loop aerial and receive loop aerial are axially aligned during stereo mode operation.

A headset system comprising:
- an electronic device capable of outputting a monaural or a stereo audio signal;
- a first headset component for receiving the monoaural or the stereo signal from the electronic device comprising:
- a first headset component housing;
- a magnetic induction transmitter comprising a transmit loop aerial disposed within the first headset component housing at a first orientation;
- and
- a second headset component capable of wireless communications with the first headset component utilizing magnetic induction communication, wherein the second headset component receives the stereo signal or a component of the stereo signal from the first headset component, the second headset component comprising:
- a second headset component housing;
- and
- a magnetic induction receiver comprising a receive loop aerial disposed within the second headset component housing at a second orientation matching the first orientation, wherein the transmit loop aerial and receive loop aerial are axially aligned when the second headset component receives the stereo signal or a component of the stereo signal from the first headset component.
6 more elements
A method for using a headset system comprising:
- generating a power-on activation or wake-up signal in a second headset component by touching the second headset component with a first headset component or bringing the second headset component within a range of approximately 3 inches or less from the first headset component;
- powering up the second headset component using a second headset component controller responsive to the power-on activation or wake-up signal;
- receiving a stereo audio signal at the first headset component;
- decoding the stereo audio signal into a first audio channel and a second audio channel, wherein the first audio channel is output by a first speaker at the first headset component;
- and
- transmitting the second audio channel to the second headset component over a wireless link, wherein the second audio channel is output by a second speaker at the second headset component.
3 more elements
A headset system comprising
- a first headset component comprising:
- a first headset component housing;
- a magnetic induction transmitter comprising a transmit loop aerial disposed within the first headset component housing;
- and
- a second headset component comprising:
- a second headset component housing;
- and
- a magnetic induction receiver comprising a receive loop aerial disposed within the second headset component housing, the magnetic induction receiver adapted to receive a signal from the magnetic induction transmitter and the receive loop aerial being so arranged as to align with the transmit loop aerial to receive the signal wherein a first audio channel is output at the first headset component and a second audio channel received from the first headset component is output at the second headset component.
