Definitions

  • This invention relates to sound producers, and more particularly to a sound producer of the type employing a flexible diaphragm whichvis caused to vibrate by the action of pulsating air pressure to which the diaphragm is subject.
  • e pressure of air supplied to the device may vary, and this will result in causing the volume of sound to vary, and the principal l0 object of mv invention is to provide a sound producer o the abovetype in which means are provided for maintainin the volume of sound constant regardlesso the degree of pressure of air supplied to the device.
  • the single ligure is a sectional view of a sound vproduc- -ing device embodying my invention'.
  • the device may comprise a casing 1 having a chamber 2 and 2 0 'a central tube 3 which extends outwardly to forni a horn.
  • a flexible diaphragm 5 is secured in the casing by a cover or cap lmember 6.
  • the member 6 is provided with a centrally disposed cylinder 7, in which ismounted a piston 8. i
  • the piston 8 is provided with a stem 9, the end of which is secured to the diaphragm 5.
  • Said lsupply p'pe is connected to a plug 18V having screw-threaded engagement in the casing 1 and having a passage 19which connects pipe 17 with chamber 2.
  • a plug 18V having screw-threaded engagement in the casing 1 and having a passage 19which connects pipe 17 with chamber 2.
  • piston 8 is Subject to If the supply pressure is low, the pressure on piston 8 will be correspondingly low, so that less resistance is oiiered to the move-A ment of the diaphragm when ,the supply pressure is low. When the supply pressure is high the resistance to the movement of the diaphragm is likewise high. l
  • AA sound roducer comprising a flexible diaphragm subject to. the pressure of fluid in av chamber and controlling an outlet openingv'fromA said chamber and operated by an increase in pressure in said chamber for connecting said chamberto saidl outlet opening and a piston 'subject to the] pressure ofizi supplied to said chamber ment of said diaphragm.
  • a sound roducer comprising a. flexible ject to the pressure of ⁇ fluid 1n a chamber and controlling an outlet opening' through which uid is vented from said chamber and a phragm and subject to the pressure of ⁇ fluid supplied to said chamber ina direction to oppose-the lluid pressure acting onsaid dia-v pmgm- 3.
