Abstract
A listening device (120; 220; 320), such as a pair of headphones, is provided for wearing by a user. It contains two or more sound emitters for directing sound to each ear (2) of the user. At least one of the sound emitters (116; 216, 316) is positioned such that sound is emitted in a direction substantially perpendicular to the axis of the ear canal (10) of the ear, and towards the wall of the concha (6) of the ear (2).
Claims16
A listening device (120;
- 220;
- 320) for wearing by a user, comprising:
- at least one support structure (112;
- 226;
- 330) for positioning on or adjacent both ears (2) of the user;
- said at least one support structure including, for each ear, one or more corresponding first sound emitters (116;
- 216;
- 316) and one or more corresponding second sound emitters (118, 218;
- 330);
- characterised in that when the listening device is worn by the user, the first and second sound emitters (116, 118;
- 216;
- 218;
- 316;
- 330) are positioned such that, for each ear:
- the one or more corresponding first sound emitters (116;
- 216;
- 316) direct sound in a different direction from the one or more corresponding second sound emitters (118, 218;
- 330);
- and
- the one or more corresponding first sound emitters (116;
- 216;
- 316) direct sound at a wall portion of the concha of the ear.
19 more elements
A method of processing signals for a listening device (120;
- 220;
- 320), comprising the steps of:
- extracting cues from sound sources;
- processing the cues to generate a plurality of sound signals;
- delivering one or more of the sound signals to one or more first sound emitters (116;
- 216, 316), and a different one or more of the sound signals to one or more second sound emitters (118;
- 218;
- 330);
- characterised in that the one or more first sound emitters emit sound in a direction which is at an angle of at least 60 degrees to the axis of an ear canal of a user.
