Abstract

249,205. Monnot, J. F. Dec. 17 1924. Diaphragm horns. - The body part A is dish-shaped and provided with a flange a for supporting the diaphragm and a recessed inwardly projecting portion a<1> in which the magnet coil is housed. The striker B and armature G are carried by leaf springs H, H', the former of which extends across the armature and carries the moving contact J of the make and break device. The spring H is laminated for a short distance at its point of attachment to the body, and both springs are laminated where they are attached to the striker. The horn E is carried by a screwed cap D which clamps the diaphragm between a pair of washers against the flange a, The working parts are protected by a detachable cover K.
