Title
(EN) AN ACOUSTIC WARNING DEVICE, PARTICULARLY FOR MOTOR VEHICLES
(FR) AVERTISSEUR SONORE DESTINE AUX VEHICULES A MOTEUR
Abstract
(EN)
The acoustic warning device comprises a casing (1) in which at least one resiliently deformable diaphragm (10, 11) is mounted. In the casing (1) there is also mounted, in a fixed position, at least one excitation winding (19, 20). A movable ferromagnetic member (8, 9), subjected in use to the magnetic field generated by the winding (19, 20), is connected to the diaphragm (10, 11). The movable ferromagnetic member (8, 9) includes a substantially bell-shaped axial end portion (8a, 9a), disposed around the winding (19, 20).
(FR)
L'avertisseur sonore de la présente invention comporte une enceinte (1). Au moins une membrane déformable par élasticité (10, 11) est montée dans ladite enceinte (1). Au moins une bobine excitatrice (19, 20) est également montée dans l'enceinte. Un élément ferromagnétique mobile (8, 9) soumis en utilisation au champ magnétique produit par la bobine (19, 20), est raccordé à la membrane (10, 11). L'élément ferromagnétique mobile (8, 9) comporte une extrémité axiale (8a, 9a) sensiblement en forme de cloche, laquelle extrémité est disposée autour de la bobine (19, 20).
