Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • Another object of the invention is to propose the use of this structure in a telephone apparatus.
  • 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.
  • 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.
  • two stops are provided, and are then advantageously located on either side of the two electrical contacts.
  • 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.
  • 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.
  • the frame i.e. forming only one piece with it, by manufacturing
  • 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).
  • FIG. 3 illustrates an example of the use of the invention in a telephone set.
  • 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.
  • 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).
  • 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.
