The disclosure presents a method and a communication system comprising; an audio gateway including; a first wireless interface configured to transmit and receive an audio signal via a first communication link, a processing unit configured to transfer the audio signal into an audio streaming signal, a second wireless interface configured to transmit the audio streaming signal via a second communication link, a plurality of communication units comprising a master communication unit and at least a first slave communication unit, wherein each of the communication unit comprises: a first wireless interface configured to receive the audio streaming signal via the second communication link and to communicate with a communication unit, a speaker configured to sound the audio streaming signal received from the audio gateway, a memory unit, and wherein the master communication unit is configured to transmit a pairing request via the second communication link to the audio gateway, and the audio gateway transmits then an encryption key to the master communication unit, and the first slave communication unit is configured to request the encryption key by transmitting an encryption request including an identification of the first slave communication unit to the master communication unit via a first internal communication link, and the master communication unit transmits then the encryption key relating to the second communication link to the first slave communication unit based on an access criteria, and the first slave communication unit is then configured to eavesdrop the audio streaming signal being communicated via the second communication link between the audio gateway and the master communication unit.

Communication system including eavesdropping

The invention relates to a wireless hearing device that comprises an ear part, an elongated part and a guide unit. The ear part is configured to be worn in an ear of the user of the hearing device and comprises a speaker unit that is arranged in an ear part housing of the ear part. The elongated part is attached to the ear part such that a distal end of the elongated part faces away from the ear part. Furthermore, the elongated part has an elongated part housing that is arranged to encompass a microphone unit with at least one microphone of the hearing device. The guide unit is arranged at the ear part such that the guide unit can be located between Tragus part and Antitragus part of the ear, while the ear part is in an operating position in the ear of the user, and wherein the guide unit allows a maintaining of a position of the ear part with respect to the ear such that the distal end of the elongated part points toward a user's mouth.

Wireless hearing device

The disclosure relates to a microphone arrangement comprising at least three groups of microphones that are mounted on a head-wearable support structure. The at least three groups of microphones comprising a first group of microphones with one or more microphones, a second group of microphones with one or more microphones, and a third group of microphones with one or more microphones, wherein the first group is mounted to a casing that accommodates signal transmission circuitry, the second group is mounted to slide with respect to the casing and the first group is mounted in a direction of a first axis. Furthermore, the third group comprises either at least one microphone that is arranged on the support structure so as to exhibit less sensitivity for sound coming from a user's mouth than for sound coming from a user's environment when the microphone arrangement is head-worn; or at least two microphones that are arranged symmetrically with respect to a user's head when the microphone arrangement is head-worn and that provide for a directionality that is orientated to the direction of a user's vision; or both.

Microphone arrangement

A mobile conference system including a first mobile master hands-free unit and a second mobile slave hands-free unit, each having a microphone, a loudspeaker, a battery unit, an operating unit, a lighting unit, and a first transmitting/receiving unit for bidirectional wireless communication between the first and second mobile hands-free units. The first mobile hands-free unit includes a second transmitting/receiving unit for wireless bidirectional audio communication with an external unit. The first mobile hands-free unit is configured to wirelessly transmit audio signals received from the external unit via the second transmitting/receiving unit to the second mobile hands-free unit via the first transmitting/receiving unit, to mix audio signals received from the second mobile hands-free unit via the first transmitting/receiving unit with audio signals recorded via the at least one microphone of the first hands-free unit, and to wirelessly transmit said audio signals to the external unit via the second transmitting/receiving unit.

Mobile conference system

An audio processing device comprises a multitude of electric input signals, each electric input signal being provided in a digitized form, and a control unit receiving said digitized electric input signals and providing a resulting enhanced signal. The control unit is configured to determine the resulting enhanced signal from said digitized electric input signals, or signals derived therefrom, according to a predefined scheme.

Method of reducing un-correlated noise in an audio processing device

A microphone boom is provided with an extendable microphone assembly, and a headset having such a microphone boom. The headset includes a casing accommodating the signal transmission circuitry and further includes a speaker adapted to serve a sound signal at the proximity of a user's ear and the speaker is protruding from the casing at a speaker-end of the casing and a microphone assembly is fixated relative to the casing distally with respect to the speaker-end.

Microphone boom

A microphone boom is provided with extendable microphone arrays, and a headset having such a microphone boom. The headset comprise a casing accommodating the signal transmission circuitry and further comprises a speaker adapted to serve a sound signal at the proximity of a users ear and the speaker is protruding from the casing at a speaker-end of the casing and one microphone array is fixated relative to the casing distally with respect to the speaker-end.
