Abstract

354,057. Electric horns. HAASIS, P., Zuffenhausen, Wurtemberg, Germany. Aug. 6, 1930, No. 23606. [Class 13.] The diaphragm a of an electric horn is secured at or near the edge to the two poles c of a threepole magnet, leaving the remainder of the diaphragm free to vibrate ; an armature d is secured to the diaphragm at points remote from the poles c, preferably on the transverse medial line, and the armature may be offset and packed from the diaphragm. A cross-bar f carrying a contact screw g is added to complete the magnetic circuit. The coil l is housed in a recess in the base. To permit the sound to escape, the base is provided with apertures k and is partly clear of the rear surface o. A cover m snaps over rivet heads n or like projections.
