Abstract

Device for listening to the sounds emitted by devices equipped with loudspeakers or speakers and a headphone jack. The invention relates to a device ensuring great reliability for these devices and providing better listening on headphones to the hearing-impaired without discomfort It consists of a switch-switch (4) attached to the devices and the constant maintenance of the headphone jack plug (3) in the headphone socket (1), this in monophonic or stereophonic. -switch (4) is open, there is listening on the headphones only (3) and when it is closed, there is listening on the headphones (3) and also on the speakers or speakers (2), this in monophonic or stereophonic; a switch placed on their cables, allows the suppression of listening on the headphones.

Description

The present invention relates to a device for listening to sounds emitted

  by devices with speakers or speakers and a headphone jack.

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

  The insertion of this plug-jack pushes one or more metal lamellae conducting current, causing the cut of the circuits of the loudspeakers or enclosures and closing those of the helmets.

  With electrical arcing caused by circuit interruptions, the repetition of switching from one listening mode to another, causing the elasticity of the slats to lose their aging, leads to the deterioration and even the suppression of the contacts. where disturbed or missing sounds.

  The device according to the invention overcomes this drawback: the headphone jack plug is still inserted into the headphone jack, a circuit switch is attached to the devices.

  The following appended drawings relate to the usual apparatus: FIG. 1 shows the jack plug of the headphones (2) inserted in the headphone jack, pushing back the conductive lamellae (1).

  FIG. 2 shows the circuitry of the loudspeakers or loudspeakers (2) before and after the insertion of the jack plug of the headphones (3) into the headphone jack (1), in monophonic or stereophonic mode.

  The following appended drawings illustrate the invention: FIG. 3 represents 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 or bipolar inverter switch (4), listening is performed either on the headphones, or on the speakers or speakers, in monophonic or stereo.

  This device is a variant of that of Figure 4 following.

  FIG. 4 represents the circuits of the loudspeakers or loudspeakers (2 ') and helmets (3), the jack plug of the helmets still being inserted into the jack. headphone jack (l) with the addition of a switch-switch. monopolar 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, an interrupter placed on their cables allows the suppression of listening on the 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 intended for listening to sounds on loudspeakers or speakers and helmets.

Claims (5)

-3-CLAIMS   1) Device for listening to sounds emitted by devices equipped with speakers or speakers and a headphone jack in that it is necessary to constantly maintain the insertion of the plug-jack of the headphones (3) in the socket headphones (l) and add to the devices a monopolar or bipolar circuit switch (4).   2) Device according to claim 1 characterized by the constant maintenance of the insertion of the plug-jack of the helmets (3) in the headphone jack (l), maintenance avoiding deterioration or disappearance of the contacts.   3) Device according to claim 1 characterized by the addition to the apparatus of a switch-inverter (4) for listening either on the headphones (3), or on the speakers or speakers (2), this in monophony or stereophony.   4) Device according to claim 1 characterized by the addition to the apparatus of a switch-switch (4) for listening either on the helmets (3), or on the helmets (3) and also on the speakers or in - girdles (2), in monophony or stereophony.   5) Device according to claims 3 and 4 characterized in that the switches (4) can be mechanical, electromagnetic or electronic relays, relays controlled by mechanical switches or various remote controls (infra-red, acoustic, tactile, etc. .. .).
