Abstract

241,650. Winter, F. M. Aug. 11, 1924. Sound-box cases; tool arms and mountings.-An aluminium, copper &c. diaphragm 7 is clamped between the stylus arm 9 and a washer 14 of mica, vulcanite, cork &c. by a metal or vulcanite screw 13 which does not contact with the diaphragm. The stylus arm foot 9<a> bears with its toe or its heel or with both on the diaphragm, the, arm being mounted on a screw 10 carrying a spring 11 which presses the arm against points mounted on the sound-box case. The volume of sound can be varied by varying the diameter of the washer 14, or by flexing the diaphragm to increase or decrease the space between it and the back 3 of the sound-box, or by a combination of those means. The diaphragm is mounted between rubber rings 8 clamped between the lip 1<a> of the case 1 and the back plate 3 to which is secured a rubber washer 4 and a flanged tube 5a.
