INSTRUMENT A VENT POUR ENCEINTE ACOUSTIQUE WIND INSTRUMENT FOR ACOUSTIC ENCLOSURE
La création de certains sons se réalise par des instruments à vent, ou quand nous parlons, à travers nos dents, il y a des sifflantes, qui disparaissent quand une dent tombe. Ce registre des sifflantes est méconnu dans la reproduction du son. Les sifflantes sont des 5 sons émis par une ou plusieurs turbulences d'air en mouvement que le présent procédé et appareils mettent en oeuvre dans des rendements acoustiques faibles très différents des chambres à compression. Le procédé est la mise en oeuvre d'une structure qui oblige l'air dans ses déplacements à réaliser des turbulences et donc des sifflantes, par une forme d'entonnoir qui génère des fluctuations de mouvement d'air par des dépressions 10 sur les parois de l'entonnoir ou de la forme conique mise en évidence sur la Fig. (1,2,3) suivant les flèches (1,2). Les mouvements d'air sont activés par l'effet ventouse de pression et de dépression(6) de membrane de transducteur électroacoustique en fonction dans l'enceinte acoustique ouverte ou close. Les contraintes de l'air sont augmentées par au moins l'adjonction d'une obstruction partielle supplémentaire sur le cône d'ou15 verture (5) agissant un peu comme une anche (3) d'un instrument à vent au moyen d'un bois coupé en biseau Fig.l. De plus, une lamelle de titane (4) peut être activée par les turbulences placée dans le cône ou l'entonnoir de ce nouveau transducteur acoustique d'une finesse inégalée. Plusieurs appareils avec des rapports dimensionnels différents répondent à des registres sonores complémentaires, qui se conjuguent parfaitement 20 ensemble, ajustés par l'homme de l'art sur au moins une des parois de l'enceinte. Les turbulences peuvent se réaliser aussi par une fente placée sur une paroi de l'enceinte fig.2, dont une tige vient dévier, couper en deux le flux initial sortant de la fente (4), o The creation of certain sounds is achieved by wind instruments, or when we speak, through our teeth, there are wheezes, which disappear when a tooth falls. This register of sibilants is unknown in the reproduction of sound. The sibilants are sounds emitted by one or more turbulences of moving air that the present method and apparatus employ in low acoustic yields very different from compression chambers. The method is the implementation of a structure which forces the air in its movements to produce turbulence and therefore whistling, by a form of funnel which generates fluctuations in the movement of air by depressions 10 on the walls. of the funnel or conical shape highlighted in Fig. (1,2,3) following the arrows (1,2). The air movements are activated by the vacuum and pressure suction effect (6) of the electroacoustic transducer membrane in operation in the open or closed acoustic enclosure. The air constraints are increased by at least the addition of an additional partial obstruction on the cone of opening (5) acting somewhat like a reed (3) of a wind instrument by means of a wood cut bevel Fig. l. In addition, a titanium strip (4) can be activated by the turbulence placed in the cone or the funnel of this new acoustic transducer of unequaled finesse. Several devices with different dimensional ratios respond to complementary sound registers, which combine perfectly together, adjusted by those skilled in the art on at least one of the walls of the enclosure. Turbulence can also be achieved by a slot placed on a wall of the enclosure fig. 2, a rod of which deflects, cutting in two the initial flow leaving the slot (4),
l'air suivant les flèches (1,2) montrent les turbulences autour de la tige(3). the air following the arrows (1,2) show the turbulence around the rod (3).
Un appareil de réalisation de l'instrument à vent d'une enceinte acoustique est constitué 25 d'un trou de trois millimètres de diamètre sur une hauteur de 5 millimètres et une fente An apparatus for making the wind instrument of an acoustic enclosure consists of a hole three millimeters in diameter over a height of 5 millimeters and a slot
en cône s'élargissant, vers l'espace ambiant de l'auditeur, suivant une pente de 30 . La largeur du cône est de 4 millimètres. Un bois, biseauté (3) vient s'encastrer dans la paroi de l'enceinte acoustique à fleur de la surface et recouvre le cône sur environ un tiers de sa longueur. Une vis (7) dans un trou houblon permet l'accord sonore ainsi retransmis. 30 L'activité (6)du ou des transducteurs électroacoustiques active l'air de l'appareil Fig. 1. in widening cone, towards the ambient space of the listener, according to a slope of 30. The width of the cone is 4 millimeters. A bevelled wood (3) is embedded in the wall of the acoustic enclosure flush with the surface and covers the cone over about a third of its length. A screw (7) in a hop hole allows the sound agreement thus retransmitted. The activity (6) of the electroacoustic transducer (s) activates the air in the device. 1.
Une variante du procédé est l'appareil(4) activé par un transducteur (8) placé derrière le trou, à proximité, Fig.3. Les appareils sont utiles pour tout le monde audio, audio visuel, téléphonie, ordinateur, médical, la transmission ou analyse sonore en particulier. A variant of the process is the device (4) activated by a transducer (8) placed behind the nearby hole, Fig.3. The devices are useful for everyone audio, audio visual, telephony, computer, medical, transmission or sound analysis in particular.
