Abstract

The electromagnetic signal horn, has a pot shaped housing a membrane fixed to its open front surface and has a vibrator system to activate it, consisting of an anchor or armature mounted to the membrane with a circuit breaker device attached to the armature with a leaf spring acting as a moving operative contact at the free end of the armature. It has the long axes of the leaf spring (22) attached to the contact surface (29) of the armature (14). The contact surface (29) of the armature partially or completely covers the long axis (x) of the leaf spring.
