Abstract

286,841. Wade, H., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Jan. 26, 1927. Diaphragms.-The diaphragm of a sound responsive instrument, such as a loud-speaker or microphone, is peripherally supported in a frame by means of a yielding strip of woollen fabric, e.g. flannel or serge. The diaphragm, which may be conical, is preferably sewn to the strip.
