Abstract: The present invention relates to a microphone apparatus (10) with a main beamformer (F, BF) that provides a directional audio output (SF) by combining microphone signals (X, Y) from multiple microphones (11, 12).The quality of beamformed microphone signals normally depends on the individual microphones having equal sensitivity characteristics across the used frequency range. The invention enables automatic adaptation of the main beamformer (F, BF) to variations in microphone sensitivity and to changes in the alignment of the microphone apparatus (10) with respect to the user's mouth (7).This is achieved by having the microphone apparatus (10): estimate a suppression filter (Z) for an optimum voice-suppression beamformer (Z, BZ) based on the microphone signals (X, Y); estimate a candidate filter (W) for a candidate beamformer (W, BW) as the complex conjugate of the suppression filter (Z); estimate the performance of the candidate beamformer (W, BW); and replace a main filter (F) in the main beamformer (F, BF) with the candidate filter (W) if the candidate beamformer (W, BW) is estimated to perform better than the current main beamformer (F, BF).The invention may be used to enhance speech quality and intelligibility in headsets 1 and other audio devices that pick up user voice.

Abstract: A headset for voice communication is disclosed, the headset comprising at least one earphone having a speaker and one or more microphones. The headset is configured to be operated in a first mode in which an electronic noise cancelling circuit is configured to receive ambient audio via at least a first of the one or more microphones to implement an active noise cancelling function and to provide a noise cancelling audio signal to the speaker, and in a second mode in which ambient audio is provided as a hear-through audio signal to the speaker. The headset for voice communication is configured to detect whether a call is ongoing, and to provide a call signal in response to the detection. The headset comprises the electronic noise cancelling circuit, a voice activity detection unit configured to indicate when a user speaks, a switching element configured to switch the headset between operating in the first mode and operating in the second mode, wherein, when the headset is operated in the first mode and the call signal indicates that the user is not in a call, the switching element is configured to switch the headset from operating in the first mode to operating in the second mode when the voice activity detection unit indicates that the user speaks.

Abstract: A headset providing audio input and output for a mobile device includes a microphone and speaker. An RF transceiver performs wireless communication with the mobile device. One or more buttons are configured for push operations to control operation of the headset, the mobile device, or both. A processor is configured to process a signal input from the microphone and output the processed signal to the RF transceiver, process a signal received from the RF transceiver and output the processed signal to the speaker, and process a signal input according to the push operations of the one or more buttons. At least one of the buttons is configurable to actuate a selected function. A memory associated with the processor stores program instructions for executing a plurality of functions, wherein the selected plurality of function is selected in response to user input via a user interface on the mobile device.

Abstract: A headband for a headset comprising a carrier, a first strap and a wrapping is disclosed. The carrier is curved to conform to a wearer's head. The first strap is attached to the carrier at two attachment points. The wrapping is attached to the carrier and arranged to conceal the first strap. The first strap and the wrapping together form a head abutment portion extending between the two attachment points and configured to abut to the wearer's head when the headband is worn by the wearer. At least one of the first strap and the wrapping comprises a flexible and elastic material configured to stretch along the length of the carrier between the two attachment points, thereby providing the head abutment portion configured to adapt to the shape of the wearer's head.
