Abstract

Devices for acoustic remote control, remote alarm, remote recognition using, as a means of production and transmission, sound signals which are audible or otherwise. They comprise several types of transmitters including that of the drawing comprising a resonator 1 and a vibrating blade 2. The receiver includes a microresonator consisting of a miniature microphone 4 enclosed in a resonator 3; it is followed by an amplifier 5 followed by a filter; the main element is a phase-locked loop (PLL) 7; the control output 9 is taken on a relay or the mains; logic 8 carries out management, the supply of power 10 is by battery or mains. All the elements are tuned to the same adjustable frequency, which ensures great selectivity. Domestic and industrial applications.

Description

La presente invention concerne des dispositifs de telé oommande,téléalarme,teléreconnaissance acoustiques utili sant comme moyen de production et de transmission des si gnaux sonores audibles ou non. The present invention relates to remote control, remote alarm, remote acoustic recognition devices using as means of production and transmission of audible or non-audible sound signals.

lie synoptique du systeme est donné fig 1,ilcomporte un ou plusieurs emetteurs 1 et un récepteur comprenant un microresonateur 2,un amplificateur 3,un filtre 4,un circuit intégré a verrouillage de phase ("phase locking look) 5, des circuits logiques 6,une alimentation 7 (pile ,secteur) et une sortie de commande 8(par relais ou pour secteur par triac). The synoptic link of the system is given in fig 1, it comprises one or more transmitters 1 and a receiver comprising a microresonator 2, an amplifier 3, a filter 4, an integrated phase locked look circuit 5, logic circuits 6 , a power supply 7 (battery, sector) and a control output 8 (by relay or for sector by triac).

L'émetteur caracteristique de l'invention est represen té fig2; il comporte une lame ou tige vibrante 1 serrée par deux vis 2 dans un support 3 ;ce support est fixé sur un résonateur acoustique 4.L'ordre de commande est donné en ébranlant I,extremité de la lame 1 avec l'ongle,le doigt ou un dispositif mecanique simple;une seule action suffit pour émettre un train d'ondes amorties reconnues par le PLL,a une frequence F qui est celle de la lame; le reso nateur émetteur,le microresonateur récepteur,le filtre, et le PLL sont bien entendu accordés sur cette frequence
F:réglage a vis pour la lame,a vis ou a coulisse pour les résonateurs,a potentiometre pour le filtre et le rlil; il est facile de changer la frequence,et la selectivité de la lame permet un grand choix de fréquences.
The characteristic transmitter of the invention is shown in fig2; it comprises a vibrating blade or rod 1 tightened by two screws 2 in a support 3; this support is fixed on an acoustic resonator 4. The order is given by shaking I, end of the blade 1 with the nail, the finger or a simple mechanical device; a single action is enough to emit a damped wave train recognized by the PLL, at a frequency F which is that of the blade; the transmitter resonator, the receiver microresonator, the filter, and the PLL are of course tuned to this frequency
F: screw adjustment for the blade, screw or slide adjustment for the resonators, potentiometer for the filter and the roller; it is easy to change the frequency, and the selectivity of the blade allows a large choice of frequencies.

lie microresonateur 2 fig 1 est également caractéris tique de l'invention:il se compose d'un microphone mini ature enfermé dans un resonateur(d'ou son nom);le micro phone peut etre un électret I fig 7 et 8 ou un disque piezoélectrique 1 fig 6 ;le résonateur est le repère 2 dans les fig 6,7et8(a coulisse dans la fig 8). lie microresonateur 2 fig 1 is also characteristic of the invention: it consists of a mini ature microphone enclosed in a resonator (hence its name); the micro phone can be an electret I fig 7 and 8 or a disc piezoelectric 1 fig 6; the resonator is the reference 2 in fig 6,7et8 (has slide in fig 8).

lie gain des résonateurs assure un rapport signal/ bruit et une sélectivité importantes qui permettent l'utilisation sans fausse alarme en ambiance domestique courante. Applications:Le récepteur seul peut reconnai tre a distance un signal sonore bien défini et quasi inaudible vu l'éloignement ou l'ambiance.  The gain of the resonators ensures a significant signal / noise ratio and selectivity which allows use without false alarms in everyday domestic environments. Applications: The receiver alone can recognize a well-defined and almost inaudible sound signal from a distance, given the distance or the atmosphere.

Un ou plusieurs resonateurs sans lame,emetteurs,fig3 groupes pres d,une source sonore en facilite la reconnais sance a distance ;application possible en reconnaissance de parole monolocuteur pour quelques mots en utilisant deux a trois miniresonateurs fixes sous le nez par un dispositif elastique ou auto collant;
lie resonateur a lame fig 2 est utilise pour des telecommandes a moyenne portee:domestiques,antivol,alarme, jouets,
La clef acoustique fig 4 permet la commande a courte distance de serrures (gaches) electriques non apparentes donc difficiles a violer;2a3 lames sont con seillees pour la securite.
One or more bladeless resonators, transmitters, fig3 groups near a sound source facilitates recognition from a distance; application possible in single speaker speech recognition for a few words using two to three mini resonators fixed under the nose by an elastic device or self adhesive;
The resonator with blade fig 2 is used for medium range remote controls: domestic, anti-theft, alarm, toys,
The acoustic key fig 4 allows the short-distance control of electric locks (strikes) not visible therefore difficult to violate; 2a3 blades are advised for security.

lie sifflet fig 5 est un sifflet ultrasonore; la longueur de ce sifflet est de 2 cm et les autres representations de la planche sont a cette echelle les dimensions des resnnateurs varient entre 1et2cm pour l'emetteur,a3cm pour le récepteur
La liste de ces applications n'est pas exhaustive.
lie whistle fig 5 is an ultrasonic whistle; the length of this whistle is 2 cm and the other representations of the board are at this scale the dimensions of the reseners vary between 1 and 2 cm for the transmitter, to 3 cm for the receiver
The list of these applications is not exhaustive.

L'interet de 14invention reside daus les faibles encombrement,poids et prix des emetteurs et une bonne fiabilite due a l'absence de pile ou accu
Une logique 6 fig7 emploie les recents progres du domaine radar pour elimlner les fausses alarmes dans les cas difficiles.
The interest of the invention resides in the small size, weight and price of the transmitters and good reliability due to the absence of battery or accu
Logic 6 fig7 uses recent progress in the radar domain to eliminate false alarms in difficult cases.
