Abstract

Acoustic device for harness-racing horses. The invention relates to an acoustic device whose purpose is to reduce the fear caused to young harnessed horses by the noise of the racetrack. It consists of a pair of acoustic capsules 1 which are placed in the horse's ears and are connected by a wire 8 in plastic insulation 9 to a box 4 comprising a microphone 5, an amplifier 6 and a potentiometer 7, which box 4 is fixed to one of the shafts of the harness within arm's reach of the driver.

Description

La presente invention concerne un appareillage accoustique à régulation de bruit destiné aux chevaux des courses attelées visant à familiariser les jeunes chevaux , jusqu'à l'age d'environ cinq ans,à- un environnement bruyant notamment à l'occasion des réunions hippiques. The present invention relates to noise-controlled acoustic equipment intended for harnessed racing horses intended to familiarize young horses, up to the age of about five years, to a noisy environment, in particular at equestrian meetings.

Elle est particulièrement adaptée aux chevaux attelés, quelque soit la nature de l'attelage (sulky ou autre) puisque dans ce cas,et contrairement aux épreuves montées ,il n'ya pas de contact physique, hormis la voix, entre le driver et son cheval,susceptible de rassurer ce dernier. It is particularly suitable for harnessed horses, whatever the nature of the team (sulky or other) since in this case, and unlike mounted tests, there is no physical contact, apart from the voice, between the driver and his horse, likely to reassure the latter.

Traditionnellement,on pallie en partie cet inconvénient à l'aide d'une paire de bouchons de mousse synthétique places à l'intérieur des oreilles du cheval et que le driver retire pendant la course en tirant sur deux fils. Traditionally, this disadvantage is partially overcome with the help of a pair of synthetic foam plugs placed inside the horse's ears and which the driver removes during the race by pulling on two wires.

Ce système a comme principaux inconvénients,dans un premier temps(bouchons enfoncés) de rendre le cheval sourd à tout ordre de son driver et dans un second temps de lui faire courir le risque d' une mise à la faute en raison de la forte décompression produite lors de l'enlévement des bouchons
Le dispositif decrit ci-après réduit ces deux inconvénients gràce à un appareillage accoustique à l'aide duquel le driver peut moduler à son gré 1' intensité du bruit perçu par le cheval.The main drawbacks of this system are, firstly (plugs pushed in) to make the horse deaf to any order from its driver and secondly to make it run the risk of being put at fault because of the strong decompression. produced when the plugs are removed
The device described below reduces these two drawbacks thanks to an acoustic apparatus with the help of which the driver can modulate at will the intensity of the noise perceived by the horse.

I1 se compose de trois éléments décrits dans la figure 1 de la planche ci- annéxbe:
- une capsule accoustique (1) insérée dans une matière synthétique molle (2) moulée à l'empreinte de l'oreille du cheval.I1 is made up of three elements described in figure 1 of the board below:
- an acoustic capsule (1) inserted in a soft synthetic material (2) molded to the imprint of the horse's ear.

Cette capsule est prolongee ,à l'intérieur de l'empreinte par un tuyau en plastique souple (3) jusqu'au tympan du cheval. This capsule is extended, inside the imprint by a flexible plastic pipe (3) to the eardrum of the horse.

- un boitier (4) comprenant
un microphone (5)
un amplificateur(6)
un potentiomètre(7)
Ce boitier (4) est fixé, comme décrit dans la figure2 sur le brancard de l'attelage à portée de main du driver permettant à ce der nier de moduler grâce au potentiomètre(7) le niveau de bruit perçu par le che= val.- a box (4) comprising
a microphone (5)
an amplifier (6)
a potentiometer (7)
This box (4) is fixed, as described in Figure 2 on the stretcher of the hitch within easy reach of the driver allowing the latter to modulate with the potentiometer (7) the noise level perceived by the che = val.

- un fil conducteur électrique gainé à l'intérieur d'un tuyau de plastique souple (9). - an electrically conductive wire sheathed inside a flexible plastic pipe (9).

Cette paire de fils est reliée à chacune des deux capsules accoustiques(l) et se rejoint ensuite au niveau de l'encolure du cheval pour former gràce à une dérivation en T, un seul fil qui rejoint leboitier(4)fixé sur le brancard près du driver. This pair of wires is connected to each of the two acoustic capsules (l) and is then joined at the neck of the horse to form, thanks to a T-branch, a single wire which joins the housing (4) fixed on the stretcher. of the driver.

Une cagoule maintient le dispositif accoustique en place dans les oreilles du cheval. A hood keeps the acoustic device in place in the horse's ears.

Grâce à ce dispositif, le cheval ne perçoit les bruits extérieurs, que par l'intermédiaire des capsules accoustiques reliées au microphone(5). Thanks to this device, the horse only perceives outside noise through the acoustic capsules connected to the microphone (5).

Le fait que celui-ci soit placé à proximité du driver privilégie ainsi la voix de ce dernier par rapport aux bruits ambiants,le potentiomètre permettant de reguler,selon les besoins, le niveau du son perçu par le cheval. The fact that it is placed near the driver thus privileges the voice of the latter over ambient noise, the potentiometer allowing to regulate, as necessary, the level of sound perceived by the horse.
