Abstract

253,943. Huguet d'Amour, P. G. June 20, 1925, [Convention date]. Diarphragms.-A diaphragm for sound recording or reproducing apparatus is formed by securing a piece of fabric &c., preferably at its centre, by a threaded rod D, cap E or nut F to a board A, the fabric then being stretched and its edges secured to a frame C supported on posts B on the board A. A diaphragm approximating to the shape shown in dotted lines is thus obtained. After stretching the fabric is coated on one or both sides with varnish &c. The diaphragm may then be detached and employed either by itself or with its edges mounted upon a suitable support, the actuating means being connected to its centre. Instead of dismounting the diaphragm, the frame C may be employed as the supporting means, in which case the posts B are replaced by boards forming a box or case, and the edges of the diaphragm are covered with a framing.
