Abstract

207,179. Aktiebolaget Filmfotofon, (Assignees of Berglund, S. 0. F. A.). Nov. 16, 1922, [Convention date]. Vibrations, indicating &c. -A receiver for sound or other vibrations of the kind in which a reflector is supported on a vibrating member in association with an inertia mass has the reflector carried by two supports arranged one above the other on the. vibrating member and has the inertia mass so disposed that the centre of gravity thereby is situated' in the lower support. The vibrating member m carries a mount p from which projects the supports o, u to which the reflector s is symmetrically attached. The support o is disposed about the centre of the member m and the lower support u carries a relatively large inertia mass w of U-shape having its centre of gravity S in said support. The support u is made resilient by forming a bend f between the limbs of which is inserted a filling of rubber d to prevent vibrations of the inertia mass.
