Arrangements and methods for generating natural directional pinna cues

A headphone arrangement that is configured to induce natural directional pinna cues, the arrangement comprising:

• at least one ear cup comprising a frame that is configured to be arranged to at least partly encircle an 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 an outside by at least one wall of the frame;
• 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 (α, δ) 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;
• wherein
• the median plane crosses a 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,
• a horizontal plane virtually divides the frame of the ear cup into an upper and a lower part,
• a frontal plane virtually divides the frame of the ear cup into a frontal part and a rear part,
• the frontal plane is perpendicular to the horizontal plane,
• the frontal plane and the horizontal plane intersect along a first axis (x), and
• the first axis (x) is perpendicular to the median plane and runs through a concha of the user when the at least one ear cup is arranged to encircle the ear of the user.
