Abstract: Disclosed is a method for optimizing noise cancellation in a headset, the headset comprising a headphone and a microphone unit comprising at least a first microphone and a second microphone, the method comprising: generating at least a first audio signal from the at least first microphone, where the first audio signal comprises a speech portion from a user of the headset and a noise portion from the surroundings; generating at least a second audio signal from the at least second microphone, where the second audio signal comprises a speech portion from the user of the headset and a noise portion from the surroundings; generating a noise cancelled output by filtering and summing at least a part of the first audio signal and at least a part of the second audio signal, where the filtering is adaptively configured to continually minimize the power of the noise cancelled output, and where the filtering is adaptively configured to continually provide that at least the amplitude spectrum of the speech portion of the noise cancelled output corresponds to the speech portion of a reference audio signal generated from at least one of the microphones.

Abstract: A headset system comprising a headset and a base station. Each of said headset and base station comprises a transceiver configured to transmit radio signals between said headset and said base station according to a first wireless communication protocol, and each of said headset and base station further comprises a transceiver configured to transmit radio signals between said headset and said base station according to a second wireless communication protocol. At least one of said headset and said base station further comprises selecting means, such as a protocol selector configured to select one of said first and second wireless communication protocols for transmission of radio signals between said headset and said base station. The protocol selector is adapted to select the first wireless communication protocol for transmission of voice communication and the second wireless communication protocol for transmission of media content.

Abstract: The present invention relates to a desktop speakerphone array processor for microphones which produces high quality sound. The microphone array has a front direction defined by the line of sight from a microphone inlet of the second microphone towards a microphone inlet of the first microphone, the array processor being connected to receive a front microphone signal from the first microphone, a rear microphone signal from the second microphone and an audio output signal representing a speaker sound emitted from a sound driver arranged near the first and second microphones and in the rearwards hemisphere with respect to the front direction of the microphone array, the array processor being configured to provide a first array signal having a first directivity pattern with a main lobe oriented in the front direction of the microphone array in dependence on the front microphone signal, the rear microphone signal and the audio output signal. The array process has a filter configured to filter the rear microphone signal using a first set of filter coefficients and a subtractor configured to subtract the filtered signal from the front microphone signal and to provide the result in a difference signal. The filter controller repeatedly performs a cross-power analysis based on the audio output signal, the front microphone signal and the rear microphone signal and to determine the first set of filter coefficients in dependence on the result of the cross-power analysis.

Abstract: A method of updating a headset system firmware and a headset system are provided. The headset system comprises a headset and a base unit, the base unit having a base unit control circuit and being configured to connect to a computer system, the base unit comprises a headset dock to receive the headset. The method comprises the steps of receiving, in the base unit control circuit, a headset system firmware update from the computer system, the headset system firmware update comprising a headset firmware update and/or a base unit firmware update, and updating the base unit control circuit with the base unit firmware update. In a base unit storage, storing the headset firmware update having a headset firmware update version and when a headset having a current headset firmware version is received in the headset dock, controlling the base unit control circuit to check whether the current headset firmware version is the same as the headset firmware update version stored in the base unit storage, and updating the current headset firmware with the stored headset firmware update if one or more conditions are fulfilled.
