Title (EN) SPEAKER WITH LOW MASS DRIVER
(FR) HAUT-PARLEUR AVEC TUBE DE FAIBLE MASSE
Abstract: front page image
(EN)A high-fidelity type loudspeaker decreases distortion and increases conversion efficiency by decreasing mass by employing a gas driver. A gas-tight enclosure (12) contains a polar gas (whose molecules are capable of exhibiting a dipole moment, e.g. carbon dioxide) at or below atmospheric conditions. A concentrated electrostatic field formed by a conductive diaphragm (14a, 14b) and a stationary electrode having an array of sharply pointed pins (20, 30, 32, 32a) causes a long string of aligned gas molecules to impart a force to the diaphragm (14a).
(FR)Un haut-parleur du type a haute fidelite diminue les distorsions et augmente le rendement de conversion en diminuant la masse en utilisant un tube a gaz. Une enceinte etanche aux gaz (12) contient un gaz polaire (dont les molecules sont capables de presenter un moment bipolaire, p.ex. du bioxyde de carbone) sous pression atmospherique ou inferieure. Un champ electrostatique concentre forme par un diaphragme conducteur (14a, 14b) et par une electrode stationnaire ayant une rangee de pointes (20, 30, 32, 32a) force un cordon allonge de molecules de gaz alignees a exercer une force sur le diaphragme (14a).
