Abstract

The device makes it possible to associate with variations in amplifier output intensities, with the aid for example of an electrocontactor, the movement in speed of linearly disposed sources. The supply to other sources, such as luminous sources, may be associated according to preferred laws. Variations in volume and/or tone are made possible through the insertion, for example, of a rheostat between the emission amplifier outputs. Applications are envisaged, at least, in the devising of sound spaces.

Description

L'invention a pour objet un dispositif d'association d'é- mission de sons à partir d'un amplificateur, permettant de créer la sensation d'un déplacement de l'origine desdits sons, et permettant aussi 11 asservissement à cette sensation d'effets, par exemple, lumineux, venant conforter ou agrémenter ladite perception. The subject of the invention is a device for associating the emission of sounds from an amplifier, making it possible to create the sensation of a displacement of the origin of said sounds, and also allowing slaving to this sensation of 'effects, for example, light, coming to consolidate or enhance said perception.

On connaît des dispositifs qui, basés sur une liaison directe de l'intensité phonique, font réagir, par exemple, des éclairages, colorés éventuellement, aux intensités de sollicitation. Cependant, aucun de ces dispositifs ne donne l'impression d'un déplacement de sources ; en outre, leur réalisation simpliste ne présente pas de fiabilité, et il faut reconnaî- tre, également, que leur matériel d'application, tout onéreux qu'il soit, ne correspond pas à des normes techniques admissibles. Devices are known which, based on a direct connection of the sound intensity, make react, for example, lighting, possibly colored, to the intensities of stress. However, none of these devices gives the impression of a displacement of sources; furthermore, their simplistic implementation is not reliable, and it must also be recognized that their application equipment, however expensive it may be, does not correspond to admissible technical standards.

L'invention se propose d'associer à la variation d'intensités de sorties d'un amplificateur la notion de vitesse en déplacement de 1 'émission de sons à l'aide d'au moins une ligne de sources d'émetteurs de sons tels que des haut-parleurs, que cette ligne soit ou non refermée sur elle-même, On pourra, en outre, associer à dette notion de déplacement de sons, au moins un déplacement correspondant, par exemple, d'éclairages ( spots, projecteurs, etc.. )
Conformément à un mode de réalisation préféré de l'inven- tion, le courant émis aux sorties de l'amplificateur alimente au moins un potentiomètre ou une bascule de potentiomètres, l'alimentation par le courant de sortie de cette bascule ou de ce potentiomètre commandant, par un rhéostat, l'alimentation, donc la vitesse, d'un moteur.Ce moteur entraîne, lui meAme,une roue ou came commandant progressivement et dégressivement, avec l'interposition de rhéostats appropriés, la successivité d'alimentation des haut-parleurs. Ceci revient à dire que, si les potentiomètres ne sont pas alimentés, le rhéostat d'alimentation de commande du moteur reste à zéro, et que, par conséquent, le moteur ne tourne pas, aucun son n'étant distribud aux hauts parleurs.The invention proposes to associate with the variation of output intensities of an amplifier the notion of speed in displacement of the emission of sounds using at least one line of sources of sound emitters such that loudspeakers, whether or not this line is closed on itself, We can, moreover, associate with debt the notion of displacement of sounds, at least one corresponding displacement, for example, of lighting (spots, projectors, etc.)
In accordance with a preferred embodiment of the invention, the current emitted at the outputs of the amplifier feeds at least one potentiometer or a flip-flop of potentiometers, the supply by the output current of this flip-flop or of this potentiometer controlling , by a rheostat, the supply, therefore the speed, of a motor. This motor drives, itself, a wheel or cam controlling progressively and degressively, with the interposition of appropriate rheostats, the successive supply of the high- speakers. This amounts to saying that, if the potentiometers are not supplied, the motor control supply rheostat remains at zero, and that, consequently, the motor does not run, no sound being distributed to the loudspeakers.

Au contraire, que le ou les potentiomètres soient sollieités, le moteur tourne à une vitesse variable en fonction de l'intensité de cette sollicitation, et distribue aux haut parleurs, avec une vitesse de déplacement fonction de l'intensité de sollicitation du ou des potentiomètres, donc, d'alimentation en courant su rhéostat, les sons émis aux sorties de l'amplificateur, avec telles correetions de volume, par rhéostats intercalaires, qu'on jugera nécessaires. On the contrary, that the potentiometer (s) are requested, the motor turns at a variable speed according to the intensity of this request, and distributes to the loudspeakers, with a speed of movement depending on the intensity of request of the potentiometer (s) , therefore, of current supply su rheostat, the sounds emitted at the outputs of the amplifier, with such volume correetions, by intermediate rheostats, which we will consider necessary.

Pourront Entre associés à ceux de déplacement de l'origine des sons, tous effets, en particulier, tous effets d'écairages, tels que ceux correspondant à la progressivité - dégressivité de l'alimentation des haut-parleurs et à leur position en ligne, correspondante ou non. Between associated with those of displacement of the origin of the sounds, all effects, in particular, all lighting effects, such as those corresponding to the progressiveness - degression of the power supply of the loudspeakers and to their position in line, matching or not.

De me, on pourra multiplier les lignes 'parallèles" de haut-parleurs, faisant répondre à chacun, en meme poste, suivant l'une ou l'autre des sollicitations, ( stéréophonie ), à l'une des sorties de l'amplificateur ; encore, on pourra décaler l'une par-rapport à l'autre, l'émission selon chaque sortie d'amplificateur. Likewise, we will be able to multiply the 'parallel' lines of loudspeakers, making each respond, in the same position, according to one or the other of the requests, (stereophony), to one of the outputs of the amplifier. ; again, one can shift one with respect to the other, the emission according to each amplifier output.

Il est enfin évident que, sans sortir du cadre de l'invention, on pourra analyser toutes les données provenant de l'amplificateur, leur adjoindre tous modificatifs ou traitements, tout en restant dans le cadre de ladite invention. It is finally obvious that, without departing from the scope of the invention, it will be possible to analyze all the data coming from the amplifier, to add any modifications or processing to them, while remaining within the scope of said invention.
