Title (EN) A METHOD AND DEVICE TO FASTEN A LOUDSPEAKER TO A CIRCUIT BOARD
(FR) PROCEDE ET DISPOSITIF DE FIXATION D'UN HAUT-PARLEUR SUR UNE PLAQUETTE DE CIRCUIT IMPRIME
Abstract:
(EN) With the intention of simplifying the manner in which a loudspeaker is mounted on a circuit board while maintaining requisite sealing and damping between the loudspeaker and the circuit board, the loudspeaker is affixed directly to the circuit board (1) by means of a double-side adhesive annulus (3) with the diaphragm of the loudspeaker facing towards the board, wherein the board has holes (4) located opposite the loudspeaker. The number of holes (4) provided and the size of the holes may be adapted to provide the best sound production in accordance with application. When a loudspeaker is mounted in this way, all components can be collected on the circuit board and therewith simplify manufacture of the telephone apparatus as such, irrespective of whether the circuit board is in the handset or some other part of the apparatus.
(FR) Dans le but de simplifier le montage d'un haut-parleur sur une plaquette de circuit imprimé, tout en conservant le contact étanche et l'amortissement nécessaires entre le haut-parleur et la plaquette, on fixe directement le haut-parleur à la plaquette (1) au moyen d'un anneaux à deux faces adhésives (3), le diaphragme du haut-parleur étant dirigé vers la plaquette, cette dernière comportant des trous (4) opposés au haut-parleur. Le nombre de trous (4) et leur dimension peuvent être adaptés, afin de produire le meilleur son possible en fonction de l'application. Quand un haut-parleur est monté de cette façon, tous les composants peuvent être rassemblés sur la plaquette, ce qui simplifie la fabrication de l'appareil téléphonique, indépendamment du fait que la plaquette se trouve dans le combiné ou dans toute autre partie de l'appareil.
