say, diaphra'gnis which are not nipped between two surfaces but are secureclby their 5 edges being pressed against elastic surfaces.-
Withsome diaphragnis and especially inicadiaphragxns 'grea-tditficulty is experienced in gettingthe diaphragm into place witliont either cockling or injnrmgit.
According to this invention the elastic sni hi fa ce is carried by the semi-circular halves '20 of s split ring and after the clisphi'sgnrhas been put-into place the endsef thehalves of. the split ring are drawn thgether by j screws.
' The drawin s illustrate an e )aratu's b made'in accordance-with this invention.

eis one half of a splitting made in she wither connected to the base Z). of the sound. box. a is the other half of the spliti'ing detaehably connected to the'ot-her half. (I by screws'cl cl.
' The diaphragm e'is held in position. by an elastic ring f which is itself fs'ecnred to the sound box by means of the two halves a and 'c of the split ring. A stylus bar 9 is attached to the diaphragm in the usual man-- ner. I
IVhnt I claim is snpporteclby the base, an elastic ring with in the split ring, means for detnehably connecting one half of the split ring to the other half,'ancl a. cliaplnngm supported at its edge 01 peripherypnly by engg ageinent with theelastic ring and be ng' iii'mly helxt in position-therein by the split ring;
