Abstract

816,698. Electric horns. GENERAL MOTORS CORPORATION. Aug. 6, 1957 [Aug. 20, 1956], No. 24730/57. Class 13. In an electric horn the open end of a casing 32 is closed by a vibratory diaphragm 24 to form a closed chamber, and the coil 54 of an electromagnet for actuating the diaphragm 24, a circuitbreaker 52 for the electromagnet, and a relay 64 for controlling the supply of current to the electromagnet are mounted on the casing 32 within the chamber.
