CA 2582473

An acoustic apparatus has permanent magnets, which have north poles and south poles magnetized alternately in a stripe-like fashion, at the front and back of a diaphragm, respectively; and has a conductor circuit wired on the diaphragm along the stripe-like poles of the permanent magnets. This offers an advantage of being able to prevent an echo. The diaphragm, permanent magnets, conductor circuit, spacer and iron plates are installed in a baffle.

L'invention concerne des aimants permanents (2, 3) possédant chacun N pôles et S pôles magnétisés alternativement en bandes qui sont disposés respectivement sur les côtés avant et arrière d'un diaphragme (1), et un circuit conducteur (4) est câblé sur le diaphragme (1) le long des pôles magnétiques en bandes des aimants permanents (2, 3). En conséquence, un effet destiné à empêcher la génération d'un écho peut être atteint. Le diaphragme (1), les aimants permanents (2, 3), le circuit conducteur (4), une entretoise (5) et des plaques de fer (6, 7) sont contenus dans une enceinte acoustique.
