Abstract
5994. Stille, C. April 21. Diaphragms; sound-box cases.-The diaphragm M of a sound-box is mounted between tubular rings G<1>, G<2> in a frame R, and the pressure on the rings is regulated by means of screws Q acting through plates W on a circular plate T, which, together with the diaphragm M, lies wholly within the ring R.
