Title (EN) AUDIO LOUDSPEAKER
(FR) HAUT-PARLEUR AUDIO
Abstract: front page image
(EN)The invention describes the incorporation of surface (12) irregularities (22) into a loudspeaker diaphragm (10) to control the resonances of the diaphragm. Through the use of the described resonance control techniques, a single loudspeaker driver is able to offer excellent performance over a wide range of the audio spectrum. The randomness of the selected features is constructed within a set of boundary conditions to accomplish a balance of achieving the desired performance.
(FR)L'invention concerne l'incorporation d'irrégularités de surface dans un diaphragme de haut-parleur pour maîtriser les résonances de ce diaphragme. A travers l'utilisation des techniques de maîtrise des résonances décrites, un unique haut-parleur individuel peut offrir une performance excellente dans une large plage du spectre audible. Le caractère aléatoire des caractéristiques choisies est forcé dans un ensemble de conditions limites pour accomplir un équilibre de performances voulues, ainsi que pour assurer que ce dispositif est pratique à fabriquer.
