Electric horn with means for controlling curvature of the striker carrier

Abstract From the Canadian patent

The horn comprises a magnetically permeable housing with an electromagnet mounted therein and a diaphragm attached thereto. The electromagnet core may have an inclined bearing surface at one end thereof. A striker is disposed between the electromagnet bearing surface and the diaphragm for movement away from and strikingly against the diaphragm, the striker being coupled to the housing by control means which includes a flexible carrier member and which is operative when the striker is moving away from the diaphragm for imparting to the carrier member a predetermined curvature to increase the potential energy thereof. In one form of the invention the control means includes a control member …
