A headphone device includes an electric input terminal for receiving an electric audio signal, an electric energy storage device, and a charging device coupled to the electric input terminal and the electric energy storage device. The charging device is configured to charge the electric energy storage device with electric energy from the electric audio signal. An audio device includes an electric output terminal for outputting an electric audio signal from an audio source of the audio device, and an audio energy supply device configured to generate an additional electric audio signal with a frequency above a first frequency value and/or a frequency below a second frequency value, and to output the additional electric audio signal via the electric output terminal.

Headphone device, audio device, and method for operating a headphone device

A method of controlling audio recording using an electronic device and an electronic device are described. The electronic device comprises a microphone arrangement having a directivity pattern. A target direction relative to the electronic device is automatically determined in response to sensor data representing at least a portion of an area surrounding the electronic device. The microphone arrangement is automatically controlled in response to the determined target direction to adjust an angular orientation of the directivity pattern relative to the electronic device.

Method of controlling audio recording and electronic device

A telecommunication device is disclosed, comprising: a microphone array comprising a plurality of microphones, wherein each microphone receives an analogue acoustic signal; a position sensing device for determining how the telecommunication device is positioned in three-dimensions with respect to a user's mouth; at least one analogue/digital converter for converting each analogue acoustic signal into a digital signal; a digital signal processor for performing signal processing on the received digital signals comprising a controller, a plurality of delay circuits for delaying each received signal based on an input from the controller and a plurality of preamplifiers for adjusting the gain of each received signal based on a gain input from the controller, wherein the controller selects the appropriate delay and gain values applied to each received signal to remove noise from the received signals based on the determined position of the telecommunication device. A method for creating and controlling a location of a virtual microphone near a telecommunication device so as to reduce background noise in a speech signal is also disclosed.

Accelerometer vector controlled noise cancelling method

A method and a control circuit for controlling an output of an audio signal of a battery-powered device are described.

Method and circuit for controlling an output of an audio signal of a battery-powered device

Methods for distributing media content between portable electronic devices enabled for media acquisition and wireless communication are disclosed. The methods comprises forming of a group of the portable electronic devices being present at a common context, providing a piece of media content to other members of the group, and collecting a piece of media content from other members of the group, respectively. Apparatuses, i.e. portable electronic devices, suitable for such media content distribution, as computer programs for implementing the media content distribution on such apparatuses, are also disclosed.
