Abstract

In a horn of the type with a membrane attached to the edge of a housing and carrying an oscillating armature excited by a winding/breaker arrangement, an electrical interference suppressor is parallel to the series circuit of the winding and breaker. The suppressor includes resistances, capacitors, diodes, zener diodes, esp. in anti-parallel, bidirectional zener diodes, varistors or combinations of these components. The suppressor may be inside a case in the housing, and there may be connections formed as contact rivets with a slot for the suppressor wires. The contact rivets may be of pure aluminium, and/or have a tinned or copper plated surface.
