Definitions

  • My invention relates to sound producing apparatus comprising a diaphragm of. sheet metal or the like, and has for its princiaal object the provision of an improved arrangement whereby such a diaphragm may be readily mounted and subjected to a uniform tensile force of any desired value.
  • FIG. 1 illustrates diflerent views of a sound producing apparatus constructed in accordance with ,my invention.
  • This apparatus comprises clamping members l and 2 which are connected together by i screws 3 and are provided at their opposed faces with wedge-shaped grooves 4 and 5.
  • grooves are adapted to receive the beveled edges of a pair of stretching rings 6 and 7 made of brass or the like and arranged to grip the edge of a diaphragm 8.
  • the ring 7 may be provided with a groove 9 arranged to register with an extension 10 on the ring 6.
  • the diaphragm 8 is positively gripped between the stretching rings 6 and 7 and it may be subjected to any 1927. ⁇ SeriaI No. 192,469.
  • a pair of clamping members provided with beveled grooves each adapted to receive an edge of one of said rings, and means arranged to force the edges of said rings into said grooves for gripping the edge of said diaphragm and stretching said rings.
