Abstract
Among other features, a boom microphone has a microphone connector; an earcup module includes an earcup connector jack to connect to a headphone and a boom lead-in to receive the microphone connector; and a control module communicates voice signals wirelessly between (a) the boom microphone and headphone and (b) a telephone.
Claims46
An apparatus comprising:
- a boom microphone having a microphone connector;
- an earcup module including an earcup connector jack to connect to a headphone and a boom lead-in to receive the microphone connector;
- and
- a control module to communicate voice signals wirelessly between (a) the boom microphone and headphone and (b) a telephone.
1 more element
An apparatus comprising
- a headphone including a power source,
- a microphone attachable to the headphone,
- control circuitry not in the headphone to control use of audio signals associated with the microphone and the headphone, and
- a power connection between the power source of the headphone and the control circuitry.
1 more element
A method comprising
- receiving from a microphone signals representative of a voice of a user wearing an active noise reducing headphone,
- signal processing the received signals to produce derived signals representative of the voice,
- delivering the derived signals to a transducer in the headphone to be played to the user,
- the signal processing causing the derived signals to be natural reproductions of the user's voice as played to the user.
1 more element
A method comprising
- receiving from a microphone signals representative of a voice of a user wearing a headphone,
- equalizing the received signals in accordance with an inverse of a transfer function of sound traveling a path from the user's mouth via the headphone to an ear of the user multiplied by a transfer function of sound traveling a path from the user's mouth to the user's ear, absent the headphone.
An apparatus comprising
- a shielded noise canceling microphone that is attached to and detachable from a noise canceling headphone.
An apparatus comprising
- a noise canceling headphone,
- a microphone connectable to the noise canceling headphone, and
- a controller separate from the microphone and connectable to the noise canceling headphone and to the microphone,
- the controller including a wireless transceiver to communicate microphone and headphone signals to and from a telephone set.
1 more element
An apparatus comprising
- a headphone,
- a microphone attachable to and detachable from the headphone and adapted to draw current from a power source in the headphone, and
- circuitry to determine the connection state of the microphone to the headphone based on detecting the drawing of current.
The apparatus of claim 37 in which the circuitry disconnects a telephone call when it determines that the microphone has been disconnected.
An apparatus comprising
- a headphone,
- a microphone attachable to and detachable from the headphone, and
- circuitry to communicate microphone and headphone signals to and from a telephone set and to disconnect a telephone call in progress at the telephone set if the microphone is detached during the call.
An apparatus comprising
- a headphone,
- a microphone, and
- a connector to attache the microphone to and attach the microphone from the headphone non-axi-symmetrically,
- the connector being configured to cause the microphone to have the same orientation relative to the mouth after the microphone is attached to the headphone as the orientation that existed when the microphone was previously attached to the headphone.
1 more element
An apparatus comprising
- a microphone, and
- a connector to attach the microphone to and detach the microphone from a headphone, the connector having a non-axisymmetric cross-section.
An apparatus comprising
- circuitry having ports for connection to a telephone set to carry telephone audio signals, to a music source to carry music audio signals, to a headphone to play audio signals, and to a microphone to convert speech to audio signals, the circuitry being configured to detect an incoming phone call while music audio signals from the source are being played in the headphone and to switch audio signals played by the headphone from the music audio signals to the telephone audio signals.
A method comprising
- detecting when a microphone associated with a headphone is no longer providing voice signals for one side of a telephone call, and
- in response to the detecting, terminating the telephone call.
