    Abstract: A headset adapter and a headset system for voice communication comprising a headset and a headset adapter as well as a method of enabling microphone transmission to a host device are provided. The headset comprises at least one earphone having a headset speaker, a headset microphone and a headset transceiver, the headset adapter being configured to interconnect the headset and a host device, the headset adapter comprising an adapter processor, a host interface, such as a host interface interconnecting the adapter processor and the host device, an adapter transceiver configured to establish a wireless communication link with the headset. The adapter furthermore comprises a controller configured to enable and disable the headset microphone. The adapter processor is configured to receive a request for headset microphone activation or microphone deactivation, for example from the host interface, and in response to receiving the request providing a control signal to the controller to enable or disable the headset microphone. The controller may thus activate the transceiver to configure the wireless communication link with the headset.

    Abstract: Noise cancelling headsets and a method of improving audio sensitivity for a headset are disclosed. The headset comprises a speaker, a microphone unit comprising at least a first and a second microphone for picking up incoming sound and generating a first audio signal generated at least partly from the at least first microphone and a second audio signal being at least partly generated from the at least second microphone, a signal processor being configured to receive and analyse the first audio signal and the second audio signal to determine one or more equalization filter coefficients, an equalization filter configured to receive the second audio signal and the one or more equalization coefficients, and to equalize the second audio signal according to the determined one or more equalization filter coefficients to provide an output audio signal, wherein the one or more equalization filter coefficient are determined so as to approximate a power spectrum of the output audio signal to a power spectrum of the first audio signal.

    Abstract: The present invention relates to a desktop speakerphone constructed to make the desktop speakerphone less space-consuming while having improved audio qualities. The desktop speakerphone preferably has two microphone clusters 6, 7 mounted at the upper side of the housing 2 closer towards respective longitudinal ends 8 of the latter, so that each microphone cluster 6, 7 can receive voice sound Av from one or more of the users. Each microphone cluster 6, 7 preferably comprises three pressure microphones 10, 11, 12. Furthermore, within each microphone cluster 6, 7, the second and third sound inlets 14, 15 are preferably arranged symmetrically on opposite sides of the respective median plane 18. Within each microphone cluster 6, 7, the relative arrangement of the three sound inlets 13, 14, 15 defines a respective microphone axis 9, 19 for each of the microphone pairs 10, 11, 10, 12. The microphone axis 9 of the first microphone pair 10, 11 extends through the first and the second sound inlet 13, 14, while the microphone axis 19 of the second microphone pair 10, 12 extends through the first and the third sound inlet 13, 15. The microphones are connected to multiple array processors, each configured to provide an array signal in dependence on two or more of the multiple microphone signals. First and second array processor configured to provide array signals in dependence on microphone signals.

    Abstract: Disclosed are a method, a first electronic audio device, and a system comprising at least a first electronic audio device and a second electronic audio device for performing audio communication between at least the first electronic audio device and the second electronic audio device. The electronic audio devices are configured for wireless communication via a wireless connection. The electronic audio devices are configured to transmit and/or receive audio directly between them via the wireless connection. The electronic audio devices comprise a speaker and a microphone. At least the first electronic audio device is configured to operate and/or communicate in at least three modes for controlling audio to be transmitted from the first electronic audio device to the speaker of the second electronic audio device: a first mode where the transmitted audio is, such as solely, an output from the speaker in the first electronic audio device; a second mode where the transmitted audio is, such as solely, an input from the microphone in the first electronic audio device; a third mode where the transmitted audio is, such as both, an output from the speaker of the first electronic audio device and an input from the microphone of the first electronic audio device.

    Abstract: The present invention relates to a controller for controlling an electronic device. The invention may e.g. be used to control a headset or another electronic device connected to the controller.The controller (1) comprises an elongate controller body (3) having a first body end (4) and a second body end (5). The controller body (3) comprises an elongate rotatable body section (10) adapted to be rotated by a user about a longitudinal axis (11) extending through the first body end (4) and the second body end (5). The rotatable body section (10) has a radially outer side surface (12) extending between a first section end (13) near the first body end (4) and a second section end (14) near the second body end (5). The rotatable body section (10) has a size and shape allowing the user to rotate the rotatable body section (10) about the longitudinal axis (11) by performing a rolling action using three or more fingers (21, 22, 23). The controller (1) further comprises a sensing means (30) adapted to detect a rotation of the rotatable body section (10) about the longitudinal axis (11) and to provide a control signal (Sc) indicating one or more control commands to the electronic device in dependence on detecting a rotation.The controller (1) is characterized in that the sensing means (30) further is adapted to distinguish between a three-finger rolling action and a corresponding two-finger rolling action and to provide the control signal (Sc) in dependence on detecting a three-finger rolling action.This may provide a controller (1) with a significantly reduced rate of “false alarms” as well as an unobtrusive, reliable and at the same time simple and easy-to-use interface to the user.

    Abstract: A headband for a headset is disclosed. The headband is configured to carry at least one earcup of the headset. The headband comprises a carrier and a foam padding. The carrier is curved to conform to a wearer's head and has a central carrier region. The foam padding is coupled to the carrier and configured to abut the wearer's head when the headband is worn by the wearer. The foam padding has a uniform shape and defines a central foam region arranged at the central carrier region and a peripheral foam region arranged outside of the central carrier region. The foam padding in the central foam region has a lower hardness than the foam padding in the peripheral foam region.
