DESCRIPTION
Haut-Parleur Hi-Fi.DESCRIPTION
Hi-Fi speaker.
Ce qui constitue l'élément nouveau dans le haut-parleur
Hi-Fi que j'ai réalisé, c'est la membrane(1) très diffèrente organe capital qui transforme en sons les mouvements mécaniques du moteur. (8) (Voir Figures 1
Cette membrane(1),dans ma réalisation,est un disque souple(1) et très résistant,en nylon ou plastique apparenté,fi- xé à la circonfèrence sur un anneau(2)de 45 centimètres de diamètre en plastique rigide de section ronde de 20 millimètres.What constitutes the new element in the loudspeaker
Hi-Fi that I realized, it is the membrane (1) very different capital organ which transforms into sounds the mechanical movements of the engine. (8) (See Figures 1
This membrane (1), in my embodiment, is a flexible disc (1) and very resistant, made of nylon or related plastic, attached at the circumference to a ring (2) 45 cm in diameter in rigid plastic of round section of 20 millimeters.
Cette membrane est tendue très fortement sur le cercle d' appui(3)de 42 centimètres par des crochets(4) filetés recevant entretoise(5)et écrous(6)permettant de régler la tension. This membrane is stretched very tightly on the 42 cm support circle (3) by threaded hooks (4) receiving spacer (5) and nuts (6) allowing the tension to be adjusted.
le cercle d'appui(3)est constitué en bois contreplaqué de 5 millimètres d'épaisseur ou également en plastique dur. the support circle (3) is made of plywood 5 millimeters thick or also of hard plastic.
La membrane(1)est reliée en son centre par un tube(7) plastique rigide de 25 millimètres de diamètre,1 millimètre d'épaisseur, et 25 millimètres de longueur, reliée disque à la bobine du moteur(8)et reçoit ainsi les impulsions de ce dernier. The membrane (1) is connected in its center by a rigid plastic tube (7) 25 millimeters in diameter, 1 millimeter thick, and 25 millimeters in length, connected disc to the motor coil (8) and thus receives the pulses of the latter.
le fond du tube(7)est fixé à la.membrane(I)par un boulon (10)en duralumin de 3 millimètres de diamètre.l'autre extrémité est collée à la bobine du moteur(8). the bottom of the tube (7) is fixed to the membrane (I) by a duralumin bolt (10) of 3 millimeters in diameter. the other end is glued to the motor coil (8).
Le moteur est classique (8):un magneto-dynamic composé d' un aimant permanent, de pièces polaires,et,d1une bobine mobile positionnée dans l'entrefer de ces pièces. The motor is conventional (8): a magneto-dynamic composed of a permanent magnet, pole pieces, and, a moving coil positioned in the air gap of these pieces.
Toutes ces pièces sont montées sur un bati en tole(9). All these parts are mounted on a sheet metal frame (9).
les notes basses et aigues sont très bien rendues et natu
relles,sans filtre et avec une seule voie. the bass and treble notes are very well rendered and natural
real, without filter and with only one way.
