摘要： A headset arrangement for virtual reality, augmented reality or mixed reality applications is configured to induce natural directional pinna cues. The arrangement comprises a support structure configured to be arranged on a user's head and to hold a display in front of the user's eyes. For each ear, the support structure comprises at least a first sound source and a second sound source, wherein, when the support structure is arranged on a user's head, the first sound source and the second sound source are arranged such that at the concha of the user a primary sound incidence direction of sound emitted by the first sound source is essentially opposing to a primary sound incidence direction of sound emitted by the second sound source. The primary sound incidence direction is the direction from which the sound emitted by a sound source reaches the concha for the first time.

摘要： A headphone arrangement is configured to induce natural directional pinna cues. The arrangement comprises at least one ear cup comprising a frame that is configured to be arranged to at least partly encircle the ear of a user, thereby defining an open volume around the ear of the user, wherein the frame is at least partially hollow, thereby providing at least one cavity on its inside that is separated from the outside by at least one wall of the frame. The arrangement further comprises at least one loudspeaker arranged within a wall of at least one of a frontal part, a rear part, an upper part, and a lower part of the frame of the ear cup, wherein the at least one loudspeaker comprises a membrane and wherein a first side of the membrane faces a cavity inside the frame and a second side of the membrane faces the outside and wherein, when the at least one ear cup is arranged to encircle the ear of the user, at least one of the at least one loudspeaker is arranged at a first angle with respect to a median plane such that at least one of its main direction of sound propagation is directed away from the median plane, and the second side of the membrane is directed away from the median plane. The median plane crosses the user's head midway between the user's ears, thereby virtually dividing the head into an essentially mirror-symmetrical left half side and right half side.

摘要： A loudspeaker arrangement comprises a first loudspeaker configured to radiate an acoustical signal, and a first microphone that is acoustically coupled to the first loudspeaker via a secondary path and that is electrically coupled to the first loudspeaker via an active noise control processing unit. During the use of the loudspeaker arrangement, the first loudspeaker is arranged at a first distance from a first active noise control target position, wherein the first active noise control target position is a position at which noise is to be suppressed, and wherein the first distance is a length of the shortest path between the first loudspeaker and the first active noise control target position through free air. The first microphone is arranged at a second distance from the first loudspeaker, wherein the second distance is a length of the shortest path between the first loudspeaker and the first microphone through free air. The first distance equals the second distance, and the position of the first microphone differs from the first active noise target position.
