Abstract: A loudspeaker device comprising a loudspeaker unit comprising a diaphragm with a first and second surface (such as the front and rear surface of the diaphragm, respectively) and an enclosure in which the loudspeaker unit is mounted such that the first surface of the diaphragm is in acoustic communication with the surroundings of the loudspeaker device. The device further comprises an internal cavity formed in the enclosure and being in acoustic communication with the surroundings of the loudspeaker device via an acoustic element. In the device, the second surface of the diaphragm is in acoustic communication with the internal cavity. The acoustic element can be varied between a state in which sound energy generated by the loudspeaker unit in the internal cavity can be emitted to the surroundings via the acoustic element and a state in which sound energy is substantially prevented from entering the surroundings via the acoustic element.
Abstract: Techniques for generating an auditory memory for an auditory event are described. An example technique includes obtaining a first audio content associated with an event in an environment. At least one attribute of the environment is determined, based on evaluating the first audio content. At least one emotional attribute associated with the event in the environment is determined, based on evaluating the first audio content. A second audio content is determined, based at least in part on the at least one attribute of the environment. A third audio content is determined, based at least in part on the at least one emotional attribute. An auditory memory including fourth audio content associated with the event in the environment is generated, based on the first audio content, the second audio content, and the third audio content.
Abstract: A headset comprising a controller configured to receive wind information comprising information relating to a direction of wind in a predetermined coordinate system, direction information relating to a direction of the headset in the predetermined coordinate system, and an input audio signal and to generate an output audio signal based on the wind information, the direction information and the input audio signal.

Abstract: A headphone device comprising active noise cancellation means (ANC) having a feedback (FB) signal path, a feed forward (FF) signal path and a sidetone signal path, where the headphone is provided with a control member (1, 11) that can be displaced or rotated between opposite positions, where the control member (1, 11) is configured such that the gain of the FF signal path and the gain of the sidetone signal path are controllable by the control member (1, 11) in such manner that when the control member (1, 11) is at one extreme position, the gain of the FF signal path is maximum and the gain of the sidetone signal path is minimum and when the control member (1,11) is at the opposite extreme position, the gain of the FF signal path is minimum and the gain of the sidetone signal path is maximum.

Abstract: The present invention describes a loudspeaker comprising a housing and a plurality of sound transducers arranged inside said housing, where the housing has two sides arranged on either side of a x-y plane with a mutual distance between said sides measured along a z-axis orthogonal to the x-y plane, and a front facing side and a rear facing side, and a top and a bottom, wherein a. A first sound transducer is arranged inside a first cavity inside said loudspeaker housing, where said first cavity has a narrow first slit in the y-direction provided in the rear facing side, where said first slit has a width z1 in the z-direction, and a length y1 in the y-direction where the length y1 in the y-direction is larger than the width z1 in the z-direction; b.
Abstract: A headphone device comprising a speaker housing and an ear-cushion, the speaker housing comprising a speaker housing side portion and the ear-cushion comprising an ear cushion side portion, where the speaker housing side portion and the ear cushion side portion respectively are configured for releasable connection, wherein said speaker housing side portion comprises a plurality of first permanent magnets provided at respective first locations on or in the speaker housing side portion; said ear cushion side portion comprises a plurality of second permanent magnets provided at respective second locations on or in the ear cushion side portion; where said first locations respectively correspond substantially to one of said second locations; where for each pair of said first and second permanent magnets, the magnetic field of a first permanent magnet, is opposite to the magnetic field of the corresponding second permanent magnet.
