Abstract

The device has headphones (3) provided with a connector-plug that is constantly maintained in a headphone plug (1) with an addition of a monopolar or bipolar switching device (4). The switching device allows listening to sound either via the headphones or via loudspeakers (2). An ON-OFF switch is placed on the cables to permit the suppression of the listening through the headphones.

Description

The present invention relates to a device for listening sounds from devices with speakers or speakers and a headphone jack.

Usually, listening on these devices is done either on speakers or speakers, or on headphones by inserting the plug-jack of these in the headphone jack.

The insertion of this plug-jack pushes one or more current-conducting metal strips, causing the circuits of the speakers or enclosures to close and closing those of the headsets.
With the electric arcs caused by the cuts of the circuits, the repetition of the passages of a mode of listening to the other one, making lose by elasticity their elasticity with the slats, entails the deterioration and even the suppression of the contacts, where disturbed or missing sounds.

• la fiche-jack des casques demeure toujours insérée dans la prise casque,
• un commutateur de circuits est adjoint aux appareils.

The device according to the invention makes it possible to remedy this drawback:

• the headphone jack is always inserted in the headphone jack,
• a circuit switch is attached to the devices.

• la figure 1 représente la fiche-jack des casques(2) insérée dans la prise casque,repoussant les lamelles conductrices(1).
• la figure 2 représente les circuits des haut-parleurs ou enceintes(2) avant et après l'insertion de la fiche-jack des casques(3) dans la prise casque(1),ce en monophonie

ou stéréophonie. The following appended drawings relate to the usual apparatus:

• Figure 1 shows the jack plug of the helmets (2) inserted into the headphone jack, pushing the conductive lamellae (1).
• FIG. 2 shows the circuits of the loudspeakers or loudspeakers (2) before and after the insertion of the jack plug of the headsets (3) in the headphone jack (1), in monophonic

or stereophony.

• la figure 3 représente les circuits des haut-parleurs ou enceintes(2) et des casques(3),la fiche-jack des casques demeurant toujours insérée dans la prise casque(1) avec l'adjonction d'un commutateur-inverseur monopolaire ou bipolaire(4),l'écoute s'effectuant soit sur les casques, soit sur les haut-parleurs ou enceintes,ce en monophonie ou stéréophonie.
  Ce dispositif est une variante de celui de la figure 4 suivante.
• la figure 4 représente les circuits des haut-parleurs ou enceintes(2) et des casques(3),la fiche-jack des casques demeurant toujours insérée dans la prise casque(1) avec l'adjonction d'un commutateur-interrupteur monopolaire ou bipolaire(4),l'écoute s'effectuant soit sur les casques, soit sur les casques et également sur les haut-parleurs ou enceintes,ce en monophonie ou stéréophonie;un interrupteur placé sur leurs câbles permet la suppression de l'écoute sur les casques.

Avec ce dispositif,les malentendants ont droit à une meilleure écoute sans gêne pour l'assistance.
Les commutateurs(4) peuvent être mécaniques,des relais électromagnétiques ou électroniques,relais commandés par des interrupteurs mécaniques ou des télécommandes diverses (infra-rouge, acoustique, tactile, etc...).The following appended drawings illustrate the invention:

• FIG. 3 shows the circuits of the loudspeakers or loudspeakers (2) and helmets (3), the jack plug of the helmets still being inserted into the headphone jack (1) with the addition of a monopolar reversing switch or bipolar (4), the listening is done either on the headphones, or on the speakers or speakers, in monophonic or stereophony.
  This device is a variant of that of Figure 4 below.
• FIG. 4 shows the circuits of the loudspeakers or loudspeakers (2) and helmets (3), the jack plug of the helmets still being inserted into the headphone jack (1) with the addition of a monopolar switch-switch or bipolar (4), the listening is carried out either on the helmets, on the helmets and also on the loudspeakers or enclosures, this in monophony or stereophonie; a switch placed on their cables allows the suppression of the listening on helmets.

With this device, the hearing impaired have the right to a better listening without hindrance for the assistance.
The switches (4) can be mechanical, electromagnetic or electronic relays, relays controlled by mechanical switches or various remote controls (infra-red, acoustic, tactile, etc ...).

The device according to the invention is particularly for listening to sounds on speakers or speakers and helmets.
