Abstract
Description
La présente invention concerne un électrophone comprenant un Jeu de lumières incorporé susceptibles de clignoter en fonction du volume du son. The present invention relates to an electrophone comprising an incorporated set of lights capable of flashing as a function of the volume of the sound.
Les dispositifs de lumière dite "psychédélique" connaissent actuellement une grande vogue. De tels dispositifs, connectés sur un électrophone, permettent d'allumer, au rythme de la musique, des groupes de lampes de couleurs différentes dont l'éclat dépend, de plus, de la fréquence du signal d'attaque. Généralement, les lampes rouges s'allument au maximum aux fréquences basses, les jaunes aux fréquences du médium et les vertes aux fréquences aiguës. The so-called "psychedelic" light devices are currently very popular. Such devices, connected to an electrophone, make it possible to light, to the rhythm of the music, groups of lamps of different colors, the brightness of which depends, moreover, on the frequency of the attack signal. Generally, the red lamps light up at low frequencies, yellow at mid frequencies and green at high frequencies.
Un tel dispositif fait intervenir des lampes puissantes et fonctionne sous une tension relativement élevée, avec tous les inconvénients que cela entrain pour l'utilisateur. Such a device involves powerful lamps and operates at a relatively high voltage, with all the disadvantages that this entails for the user.
En particulier, ce dispositif est relativement comateux, grand consommateur d'énergie et d'utilisation dangereuse pour les enfants. De plus, il se présente généralement comme un ensemble indépendant, branchable sur l'électrophone, donc encombrant.In particular, this device is relatively comatose, large consumer of energy and dangerous use for children. In addition, it is generally presented as an independent assembly, pluggable into the electronic phone, therefore bulky.
La présente invention concerne un électrophone à jeu de lumières, destiné principalement à l'usage des enfants, qui ne présente aucun danger, qui soit d'un prix modique et ait une consommation a'énergie négligeable. The present invention relates to a light-playing electrophone, intended mainly for the use of children, which presents no danger, which is inexpensive and has negligible energy consumption.
L'électrophone selon l'invention se caractérise en ce qu'il utilise des lucioles colorées de faible puissance, montées en série et alimentées au moyen d'un circuit pilote par un faible courant prélevé sur le haut-parleur de l'élec- phone, lesdites lucioles ainsi que le circuit pilote étant incorporés dans la structure de l'électrophone ou des enceintes acoustiques éventuellement associées à lélectro- phone. The electrophone according to the invention is characterized in that it uses colored fireflies of low power, connected in series and supplied by means of a pilot circuit by a low current taken from the loudspeaker of the telephone. , said fireflies as well as the pilot circuit being incorporated in the structure of the electronic telephone or of the acoustic speakers possibly associated with the electronic telephone.
Aucun filtrage n'étant prévu, il n'y a pas de séparation du signal en canaux de fréquences. Il en résulte que les lucioles clignotent non pas en fonction de la fréquence du signal reçu, mais plutôt du volume du signal. D'autre part, du fait que les lucioles sont montées en série, elles clignotent simultanément. La tension de service des lucioles est très faible, ce qui ne présente donc aucun danger pour les enfants. Since no filtering is provided, there is no separation of the signal into frequency channels. As a result, the fireflies blink not as a function of the frequency of the received signal, but rather of the volume of the signal. On the other hand, because the fireflies are mounted in series, they flash simultaneously. The operating voltage of the fireflies is very low, which therefore poses no danger to children.
On obtient ainsi un jeu de lumières capable de rythmer la musique, en fonction du volume il est vrai, mais qui suffit pour créer, chez les enfants et les jeunes, une ambiance comparable à celle des dispositifs sophistiqués de lumière psychédélique. We thus obtain a play of lights capable of rhythmic music, according to the volume it is true, but which is enough to create, in children and young people, an atmosphere comparable to that of sophisticated psychedelic light devices.
Un mode de réalisation de l'invention sera décrit à présent à titre d'exemple non limitatif, en regard du dessin annexé dans lequel
La figure 1 est un schéma-bloc du circuit d'alimentation des lucioles
La figure 2 montre un montage possible de lucioles sur un électrophone, et
La figure 3 montre un autre montage des lucioles à l'intérieur dune enceinte acoustique.An embodiment of the invention will now be described by way of nonlimiting example, with reference to the appended drawing in which
Figure 1 is a block diagram of the firefly supply circuit
FIG. 2 shows a possible mounting of fireflies on an electrophone, and
Figure 3 shows another arrangement of the fireflies inside an acoustic enclosure.
Avec référence à la figure 1 la référence 10 désigne l'amplificateur basse fréquence de l'électrophone. Le signal émis à la sortie de l'amplificateur est communiqué d'une part au haut-parleur 12 et d'autre part au circuit pilote 14. A la sortie de ce dernier sont connectées en série plusieurs lucioles 16, 18, deux dans le cas de la figure 1, ayant chacune une couleur différente. With reference to FIG. 1, the reference 10 designates the low frequency amplifier of the electrophone. The signal emitted at the output of the amplifier is communicated on the one hand to the loudspeaker 12 and on the other hand to the pilot circuit 14. At the output of the latter are connected in series several fireflies 16, 18, two in the case of Figure 1, each having a different color.
Le circuit pilote peut être constitué par un simple amplificateur de courant de tout type connu. The pilot circuit can be constituted by a simple current amplifier of any known type.
Dans le mode de réalisation particulier de la figure 2, le circuit-pilote est incorporé dans le bottier 20 de l'électrophone. Le circuit pilote est connecté par le conducteur bifilaire 22 aux lucioles, lesquelles sont montées derrière un réflecteur 24 fixé sur un pied 26 qui fait saillie au centre de la face interne du couvercle 28 de 1' électrophone. In the particular embodiment of FIG. 2, the pilot circuit is incorporated in the case 20 of the electrophone. The pilot circuit is connected by the two-wire conductor 22 to the fireflies, which are mounted behind a reflector 24 fixed on a foot 26 which projects in the center of the internal face of the cover 28 of the electrophone.
Selon l'invention, sur ladite face du couvercle est appliquée une plaque réfléchissante 30 qui prend des reflets changeants selon la lumière projetée par les lucioles. Une telle plaque est vendue dans le commerce sous le nom de "dalle psychédélique". Le conducteur 22 aboutit au niveau du pied 26. According to the invention, on said face of the cover is applied a reflective plate 30 which takes changing reflections according to the light projected by the fireflies. Such a plate is sold commercially under the name of "psychedelic slab". The conductor 22 ends at foot 26.
Dans le mode de réalisation de la figure 3, les lucioles et le circuit pilote sont incorporés dans enceinte acoustique 32. Les lucioles émettent leur lumière à travers-des filtres colorés 34, 36 montés dans des fenetres percées dans l'enceinte acoustique. In the embodiment of FIG. 3, the fireflies and the pilot circuit are incorporated in an acoustic enclosure 32. The fireflies emit their light through colored filters 34, 36 mounted in windows pierced in the acoustic enclosure.
