Abstract

The device includes a microphone (8) and case (5) which are separated by an arm (6). The arm hooks on the earpiece (3) of the portable telephone (1) so that the microphone is central over the earpiece. Alternately, the earpiece and case can be positioned at a distance from each other. The amplifier consists of a pre-amplifier and a power amplifier and the power supply is a rechargeable battery which can be recharged during dormant periods.

Description

DISPOSITIF AMPLIFICATEUR D'ECOUTE
POUR TELEPHONE PORTABLE
L'invention concerne un dispositif amplificateur d'écoute pour téléphone portable, destiné à permettre une écoute par plusieurs personnes lors d'une communication téléphonique transmise sur un téléphone portable.LISTENING AMPLIFIER
FOR PORTABLE TELEPHONE
The invention relates to a listening amplifier device for a mobile phone, intended to allow listening by several people during a telephone communication transmitted over a portable telephone.

Un téléphone portable n'est pas susceptible, en général, d'être relié à une installation d'amplification permettant à plusieurs personnes de suivre la communication transmise sur le téléphone portable. A mobile phone is not generally capable of being connected to an amplification installation allowing several people to follow the communication transmitted on the mobile phone.

Un but de l'invention est de proposer un dispositif permettant à plusieurs personnes de suivre une telle communication. An object of the invention is to propose a device allowing several people to follow such a communication.

Un autre but de l'invention est de proposer un dispositif de ce type, qui soit amovible. Another object of the invention is to propose a device of this type, which is removable.

L'invention a pour objet un dispositif amplificateur d'écoute pour téléphone portable, caractérisé en ce qu'il est constitué, sous forme autonome, par un microphone, une chaîne d'amplification et un haut-parleur, l'ensemble étant alimenté par une batterie, et en ce que le microphone est placé sensiblement au centre de l'écouteur du téléphone portable. The subject of the invention is a listening amplifier device for a mobile phone, characterized in that it is constituted, in autonomous form, by a microphone, an amplification chain and a loudspeaker, the whole being powered by a battery, and in that the microphone is placed substantially in the center of the earpiece of the mobile telephone.

Selon d'autres caractéristiques de l'invention
- la chaîne d'amplification, le haut-parleur et la batterie sont placés dans un boîtier
- le microphone et le boîtier sont séparés par un bras d'accrochage du dispositif sur l'écouteur du téléphone portable.According to other features of the invention
- the amplifier chain, the loudspeaker and the battery are placed in a box
- the microphone and the housing are separated by an arm for attaching the device to the earpiece of the mobile phone.

D'autres caractéristiques ressortent de la description qui suit faite avec référence au dessin annexé qui représente
Figure 1 - une vue d'un téléphone portable muni du dispositif amplificateur d'écoute selon l'invention
Figure 2 - un schéma électrique simplifié du dispositif amplificateur d'écoute de la figure 1. Other characteristics appear from the following description made with reference to the attached drawing which represents
Figure 1 - a view of a portable telephone provided with the listening amplifier device according to the invention
Figure 2 - a simplified electrical diagram of the listening amplifier device in Figure 1.

Sur la figure 1, le téléphone portable est symbolisé par un combiné 1 muni d'une antenne 2. Le combiné 1 comprend notamment un écouteur 3 et un microphone 4. In FIG. 1, the mobile telephone is symbolized by a handset 1 provided with an antenna 2. The handset 1 notably comprises an earpiece 3 and a microphone 4.

Le dispositif amplificateur d'écoute selon l'invention comporte un boîtier 5 muni d'un bras d'accrochage 6 destiné à la fixation du boîtier 5 sur l'écouteur 3 du téléphone portable. The listening amplifier device according to the invention comprises a housing 5 provided with a hooking arm 6 intended for fixing the housing 5 to the earpiece 3 of the mobile telephone.

Le boîtier 5 est placé de préférence au revers du combiné 1. Le bras 6 se prolonge par une partie 7 placée contre la face de l'écouteur 3. Cette partie 7 porte un microphone 8 placé sensiblement au centre de l'écouteur 3, mais de manière à ne pas gêner l'écoute par l'utilisateur du téléphone portable. Le microphone 8 est relié au boîtier 5 par un conducteur logé dans le bras 6. Le circuit électronique contenu dans le boîtier 5 est représenté sur la Figure 2. The housing 5 is preferably placed on the back of the handset 1. The arm 6 is extended by a part 7 placed against the face of the earpiece 3. This part 7 carries a microphone 8 placed substantially in the center of the earpiece 3, but so as not to interfere with listening by the user of the mobile phone. The microphone 8 is connected to the housing 5 by a conductor housed in the arm 6. The electronic circuit contained in the housing 5 is shown in FIG. 2.

Le microphone 8 est relié à un préamplificateur 9, lui-même relié à un amplificateur 10 de puissance, qui à son tour alimente un haut-parleur 11. Une batterie 12 fournit l'énergie électrique nécessaire au fonctionnement de l'ensemble du circuit de la Figure 2. Cette batterie 12, ou pile, est de préférence rechargeable pendant les périodes de non-utilisation du téléphone portable. The microphone 8 is connected to a preamplifier 9, itself connected to a power amplifier 10, which in turn supplies a loudspeaker 11. A battery 12 provides the electrical energy necessary for the operation of the entire circuit of Figure 2. This battery 12, or battery, is preferably rechargeable during periods of non-use of the mobile phone.

Dans une variante de réalisation non représentée, le boîtier 5 n'est pas placé au revers du combiné 1, mais à distance de celui-ci. Dans ce cas, le bras 6 d'accrochage n'est utilisé que pour porter le microphone 8, et un conducteur relie le microphone 8 au boîtier 5. In an alternative embodiment not shown, the housing 5 is not placed on the back of the handset 1, but at a distance therefrom. In this case, the attachment arm 6 is only used to carry the microphone 8, and a conductor connects the microphone 8 to the housing 5.

Le fonctionnement du dispositif amplificateur d'écoute est le suivant, en supposant que le microphone 8 a été placé devant l'écouteur 3 de manière à ne pas gêner l'écoute par l'utilisateur du téléphone portable, tout en étant situé entre l'écouteur 3 et l'oreille de l'utilisateur. The operation of the listening amplifier device is as follows, assuming that the microphone 8 has been placed in front of the earpiece 3 so as not to interfere with listening by the user of the mobile telephone, while being situated between the earpiece 3 and the user's ear.

Les signaux recueillis par le microphone 8 sont traités par le préamplificateur 9, puis par l'amplificateur 10 de puissance, et enfin sont transmis au haut-parleur 11 de sorte qu'un tiers placé à proximité du boîtier 5 puisse entendre la communication adressée sur le téléphone portable. The signals collected by the microphone 8 are processed by the preamplifier 9, then by the power amplifier 10, and finally are transmitted to the loudspeaker 11 so that a third party placed near the box 5 can hear the communication addressed on mobile phone.

L'invention a été décrite dans un mode particulier de réalisation mais sa portée n'est nullement limitée à ce mode. The invention has been described in a particular embodiment, but its scope is in no way limited to this mode.

En particulier, la chaîne d'amplification constituée par le préamplificateur 9 et l'amplificateur 10 peut être modifiée dans sa structure sans sortir du cadre de l'invention.  In particular, the amplification chain constituted by the preamplifier 9 and the amplifier 10 can be modified in its structure without departing from the scope of the invention.
