Description

La présente invention concerne un haut-parleur comprenant une armature sur laquelle est fixée d'une part une membrane de transduction électroacoustique et d'autre part deux contacts pour la connexion électrique du haut-parleur. L'invention concerne également tout équipement comprenant au moins un haut-parleur associé à des circuits électroniques réalisés sur une carte de circuit imprimé, et par exemple un appareil téléphonique comprenant notamment, dans un boítier, un haut-parleur associé à une carte de circuit imprimé, ledit haut-parleur comprenant une armature sur laquelle est fixée d'une part une membrane de transduction électroacoustique et d'autre part deux contacts pour la connexion électrique du haut-parleur et de ladite carte.The present invention relates to a loudspeaker comprising a frame on which is fixed on the one hand a electroacoustic transduction membrane and secondly two contacts for the electrical connection of the loudspeaker. The invention also relates to any equipment comprising at at least one speaker associated with electronic circuits made on a printed circuit board, for example a telephone set comprising in particular, in a box, a loudspeaker associated with a printed circuit board, said loudspeaker comprising a frame to which is fixed on the one hand an electroacoustic transduction membrane and on the other hand two contacts for the electrical connection of the speaker and said card.

L'association d'un haut-parleur et d'une carte de circuit imprimé à laquelle il est relié par contacts électriques est réalisée dans de nombreux équipements, tels qu'autoradios ou téléphones. Le brevet US n° 5168527 décrit une telle structure : un haut-parleur relié électriquement à une carte de circuit imprimé est fixé sur celle-ci par un ou plusieurs ergots servant à la fois au centrage précis du haut-parleur et à son maintien à une distance appropriée de la carte. Une structure de cette sorte n'est cependant adaptée qu'à la situation dans laquelle les connexions avec la carte sont réalisées à l'aide de fils conducteurs immobilisés sur celle-ci par soudure ou tout autre moyen équivalent, et où le haut-parleur est lui-même centré et immobilisé par rapport à la carte, à une distance réglable selon les crans utilisés sur les ergots.The combination of a speaker and a card printed circuit to which it is connected by contacts electrical is carried out in many equipment, such than car radios or phones. U.S. Patent No. 5,168,527 describes a such structure: a loudspeaker electrically connected to a printed circuit board is attached to it by one or several lugs serving both for precise centering of the loudspeaker and keeping it at an appropriate distance from the menu. A structure of this kind is however not suitable than the situation in which connections with the card are made using conductive wires immobilized on this by welding or any other equivalent means, and where the speaker is itself centered and immobilized in relation to the card, at a distance adjustable according to the notches used on the lugs.

Un premier but de l'invention est de proposer un autre type de haut-parleur, correspondant à un autre mode d'assemblage et de connexion électrique par rapport à la carte de circuit imprimé.A first object of the invention is to propose a other type of speaker, corresponding to another mode assembly and electrical connection to the board printed circuit board.

A cet effet l'invention concerne un haut-parleur tel que défini dans le préambule de la description et qui est en outre caractérisé en ce que les deux contacts électriques sont des lames conductrices déformables auxquelles est associée, sur l'armature du haut-parleur, au moins une butée de limitation de la déformation desdites lames, située au voisinage de celles-ci.To this end, the invention relates to a loudspeaker as defined in the preamble to the description and which is further characterized in that the two electrical contacts are deformable conductive strips to which associated, on the frame of the loudspeaker, at least one stop of limitation of the deformation of said blades, located at neighborhood of these.

Un autre but de l'invention est de proposer l'utilisation de cette structure dans un appareil téléphonique.Another object of the invention is to propose the use of this structure in a telephone apparatus.

A cet effet, l'invention concerne un appareil téléphonique caractérisé en ce que les deux contacts du haut-parleur sont des lames conductrices déformables, destinées à venir en contact avec des connexions correspondantes de la carte, et auxquelles est associée, sur l'armature du haut-parleur, au moins une butée de limitation de la déformation desdites lames. De préférence deux butées sont prévues, et sont alors situées avantageusement de part et d'autre des deux contacts électriques.To this end, the invention relates to an apparatus telephone characterized in that the two speaker contacts are deformable conductive strips, intended for come into contact with corresponding connections of the card, and with which is associated, on the frame of the loudspeaker, at least one deformation limitation stop said blades. Preferably two stops are provided, and are then advantageously located on either side of the two electrical contacts.

Les particularités de l'invention apparaítront de façon plus précise dans la description qui suit et dans les dessins annexés, donnés à titre d'exemple non limitatif et dans lesquels :

  • les figures 1 et 2 montrent un mode de réalisation de l'invention, en vue de profil et de face respectivement ;
  • la figure 3 montre un exemple d'utilisation de l'invention dans un appareil téléphonique.
The features of the invention will appear more precisely in the following description and in the accompanying drawings, given by way of non-limiting example and in which:
  • Figures 1 and 2 show an embodiment of the invention, in side view and from the front respectively;
  • Figure 3 shows an example of use of the invention in a telephone set.

Le haut-parleur représenté très schématiquement en vue de profil sur la figure 1 et en vue de face sur la figure 2 comprend une armature 10 portant d'une part, d'un côté, une membrane 20 de transduction électroacoustique et d'autre part, de l'autre côté, deux contacts électriques 30a et 30b. Ces deux contacts sont dans le cas présent deux lames conductrices déformables, formant ressort, destinées à permettre la connexion électrique du haut-parleur.The loudspeaker represented very schematically in side view in Figure 1 and front view in Figure 2 comprises a frame 10 carrying on the one hand, on one side, a electroacoustic transduction membrane 20 and on the other hand, on the other side, two electrical contacts 30a and 30b. These two contacts are in this case two conductive blades deformable, forming a spring, intended to allow the speaker electrical connection.

A ces contacts est associée au moins une butée 40, solidaire de l'armature (c'est-à-dire ne formant qu'une pièce avec elle, par fabrication), orientée du côté des contacts, et située dans leur voisinage. Par au moins une butée, il faut entendre que celle-ci est suffisante à obtenir l'effet technique souhaité, qui est la limitation de la course des contacts lorsqu'une pression s'exerce sur eux, afin d'empêcher leur écrasement, soit au montage, soit même lors d'une chute accidentelle. On notera cependant qu'un mode de réalisation préférentiel de l'invention inclut deux butées 40a et 40b, et situées de préférence juste de part et d'autre des deux contacts (mais un nombre de butées supérieur serait possible).At least one stop 40 is associated with these contacts, secured to the frame (i.e. forming only one piece with it, by manufacturing), oriented on the contact side, and located in their vicinity. By at least one stop, you must hear that this is enough to achieve the effect desired technique, which is the limitation of the travel of contacts when pressure is exerted on them, in order to prevent their crushing, either during assembly or even during a fall accidental. Note however that an embodiment preferred of the invention includes two stops 40a and 40b, and preferably located just on either side of the two contacts (but a higher number of stops would be possible).

La figure 3 illustre un exemple d'utilisation de l'invention dans un appareil téléphonique. Un tel appareil, non représenté dans tous ses éléments, comprend notamment un boítier 50, en matériau isolant électriquement, destiné à contenir tout les organes, mécaniques ou électriques, de l'appareil. Seule une fraction de ce boítier est représentée sur la figure 3, celle qui est destinée à recevoir le haut-parleur de l'appareil. La membrane 20 est tournée vers l'extérieur du boitier 50 et donc de l'appareil, tandis que la face du haut-parleur qui porte les contacts 30a et 30b est tournée vers l'intérieur de l'appareil. Lors du montage des éléments de l'appareil, une carte de circuit imprimé 60, portant les circuits électroniques avec lesquels le haut-parleur doit être connecté, est appliquée contre la face correspondante du haut-parleur, pour établir la liaison électrique entre lesdits circuits électroniques (portés par la carte) et les contacts 30a et 30b (portés par le haut-parleur). Grâce aux butées 40a et 40b dont l'armature du haut-parleur est munie, la déformation des lames déformables formant les contacts 30a et 30b est limitée, c'est-à-dire que la hauteur des butées est calculée pour que cette déformation reste dans la limite de la déformation élastique desdites lames, sans aller jusqu'à l'écrasement qui pourrait se produire en l'absence des butées. Ces butées, dont la fabrication est réalisable d'une seule pièce avec l'armature du haut-parleur, permettent, en quelque sorte, d'ajuster l'effet de pression, volontaire ou accidentel, sur les contacts électriques.Figure 3 illustrates an example of the use of the invention in a telephone set. Such a device, no represented in all its elements, includes in particular a box 50, made of electrically insulating material, intended for contain all the organs, mechanical or electrical, of the device. Only a fraction of this case is represented in FIG. 3, the one which is intended to receive the loudspeaker of the device. The membrane 20 is turned towards the outside of the case 50 and therefore of the device, while the face of the speaker carrying the contacts 30a and 30b is facing the interior of the device. When mounting the components of the apparatus, a printed circuit board 60, carrying the electronic circuits with which the speaker must be connected, is applied against the face speaker, to establish the connection electric between said electronic circuits (carried by the card) and contacts 30a and 30b (carried by the loudspeaker). Thanks to the stops 40a and 40b, the speaker frame of which is provided, the deformation of the deformable blades forming the contacts 30a and 30b is limited, i.e. the height stops is calculated so that this deformation remains in the limit of the elastic deformation of said blades, without go to the crash that could happen in the absence of the stops. These stops, the manufacture of which is achievable in one piece with the speaker frame, allow, in a way, to adjust the pressure effect, voluntary or accidental, on the electrical contacts.
