Abstract

The loudspeaker (13) support platform (4) is rotated about its vertical axis (6) by a roller (2) on the shaft of a reversible induction motor (1). 60 micro-contacts (9) distributed around the inside of a fixed ring (3) can be actuated by a pointer on the edge of the platform. Manual or programmed computer control affords a choice of continuous rotation in either direction, to-and-fro rotation, and immobilisation in any of 60 angular positions. Power is supplied via brass slip-rings (7a,7b), and sound by a wireless infrared link (12).

Description

HAUT-PARLEUR MOBILE
La présente invention a pour objet un dispositif tournant ou pivotant lié a un haut-parleur pour ainsi faire tourner celui-ci et le son qu'il produit, afin d'obtenir des conditions d'écoute plus proches à la perception sonore de la réalité.MOBILE SPEAKER
The present invention relates to a rotating or pivoting device linked to a loudspeaker so as to rotate the latter and the sound it produces, in order to obtain listening conditions closer to the sound perception of reality. .

Jusqu'alors les installations acoustiques haute fidélité et spécialement la disposition des haut-parleurs dans l'espace ,ont été définies d'une manière statique
La présente invention propose de faire tourner les hautparleurs pour balayer les murs les entourant. Ainsi le son parcourt entre le haut-parleur et l'oreille, des distances d'infimes différences ; il module l'espace et l'écoute. Until now high fidelity acoustic installations and especially the arrangement of loudspeakers in space have been defined in a static way
The present invention proposes to rotate the speakers to sweep the walls surrounding them. Thus the sound travels between the speaker and the ear, distances of infinitesimal differences; it modulates space and listening.

Le son "arrondit les angles des murs" et devient tridimensionnel
Le haut-parleur (13) est monté sur un dispositif tournant un plateau (4) qui tourne autour d'un axe (6). Ce plateau est entrainé par un galet (2) monté sur l'axe d'un moteur asynchrone (1) qui peut marcher dans les deux sens
Soixante micro-contacts (9), disposés sur un anneau périphérique (3),peuvent être déclanchés par le pointeur (10) . L'affectation des micro-contacts, détermine la nature du mouvement du plateau-tournant ; selon leurs afectations ,il est ainsi possible d'obtenir un mouvement continu dans une ou l'autre direction ,d'obtenir un mouvement de "va et vient" ,ou de programmer l'arrêt sur 60 positions égale à 6 sur 360" . The sound "rounds the angles of the walls" and becomes three-dimensional
The loudspeaker (13) is mounted on a device rotating a plate (4) which rotates around an axis (6). This plate is driven by a roller (2) mounted on the axis of an asynchronous motor (1) which can work in both directions
Sixty micro-contacts (9), arranged on a peripheral ring (3), can be triggered by the pointer (10). The assignment of the micro-contacts determines the nature of the movement of the turntable; according to their infections, it is thus possible to obtain a continuous movement in one or the other direction, to obtain a movement of "back and forth", or to program the stop in 60 positions equal to 6 out of 360 ".

Le choix des mouvements ,peut se faire manuellement ou bien être programmé par ordinateur.The choice of movements can be done manually or can be programmed by computer.

L'ensemble de ce dispositif peut être industrialisé dans toutes ou seulement certaines phases de sa capacité à se mouvoir; il peut y avoir plus ou moins de microcontacts offrant le choix d'un mouvement "va et vient" et d'un mouvement continu ou seulement l'un des deux mouvements . Dans une application robotique ,le moteur asynchrone ,peut être remplacé par un moteur pas à pas
L'alimentation électrique du plateau-tournant , est assurée par deux anneaux en laiton (7a-7b) fixés sur son axe ,en contact avec des charbonfroteurs (8a-8b) fixés sur son socle.The whole of this device can be industrialized in all or only certain phases of its ability to move; there can be more or less microcontacts offering the choice of a movement "back and forth" and a continuous movement or only one of the two movements. In a robotic application, the asynchronous motor can be replaced by a stepper motor
The electrical supply of the turntable is provided by two brass rings (7a-7b) fixed on its axis, in contact with charcoal burners (8a-8b) fixed on its base.

Ainsi la transmission du courant est assurée pendant le déroulement du mouvement . Le haut-parleur fixé sur le plateau-tournant(4) ,est relié à un amplificateur -220 volts-, le son est transmis par un système infrarouge(12) ,sans fil
L'ensemble de ce dispositif peut être posé ou suspendu Thus the transmission of the current is ensured during the course of the movement. The loudspeaker fixed on the turntable (4), is connected to an amplifier -220 volts-, the sound is transmitted by an infrared system (12), wirelessly
This whole device can be installed or suspended
