Abstract
An electro-magnetic car horn has a trumpet-shaped section that is mounted securely and accurately on the diaphragm section using a plastics ring. The diaphragm is secured at the periphery of the peened over edges of the housing. The edge of the housing has an internal angled surface that provides location for a plastic ring insert (7) which is accurately located. The profile trumpet section of the horn (20) has a compression section (17) and expansion section (18). The unit locates in the bore of the plastic ring and may either be soldered or ultra sonically bonded.
