摘要
An electrical horn has a hollow body (19) fitted with a diaphragm (71) secured to an armature (74). A self-supporting coil (24) is disposed with clearance in a recess (23) in the body (19). The coil (24) has no central former but is provided with upper and lower elettrically insulating flanges (25) and (26). The flange (25) has laterally projecting support portions (27 and (28) engaging the body (19). The support portion (28) has an integral upstanding port (59) fitted with an electrically conducting sleeve (60). Mounted in stacked relationship on the support portion (28) and around the port (59) and sleeve (601 are an eyelet (56) and an electrical connector (54). The post (59) and sleeve (60) are deformed to produce a head which holds the eyelet (56) and electrical connector (54) in engagement, without the need to use a rivet extending through the support portion (28) and the body (19). This reduces the risk of entry of water into the body in service. The lack of a central former for the coil improves air circulation, therearound.
