Definitions

  • Another feature of this invention resides in its application to a loud speaking receiver whereby the radiation resistance per unit area of the diaphragm thereof at the lower frequencies is effectively increased by providing an acoustic path from the rear surface to the front surface of said diaphragm which at its outlet, in close proximity to said diaphragm, is substantially the same area as that of the diaphragm, said acoustic path defining an acoustic lter.
  • Fig. 7 shows a front view of still another embodiment of this invention.
  • Fig. 8- is a sectional view of the embodiment shown in Fig. 7 taken along the line 8-8; 4.
  • Fig. 12 shows graphically the operating characteristics in the low portion of the frequency range of the device shown in Fig. 9 and of the same device without features of this invention.
  • the ring 55 is provided with a tapered inner surface 67 to substantially eliminate the increase in pressure on the diaphragm caused by the resonance of the chamber above the diaphragm.
  • the duid in said passage having a mass substantially equal to the edective mass of said diaphragm and said driving means and the duid in said enclosure an acoustic stidness such that the low frequency sounds translated by the enclosed surface of said diaphragm act through said stiffness and mass to reenforce the sounds translated by' the other surface of said diaphragm.
