Application April 16, 1956, Serial No. v578,254
1 Claim. (Cl. 181-18) The present invention relates generally to underwater breathing apparatus and more particularly to a speaking device for use therewith.
It is a major object of the present invention to provide a new and novel underwater speaking device.
`,A more particular object is to provide a speaking device which may be used with underwater breathing apparatus so as to permit a diver to vocally communicate with others located either below the water or at the surface thereof. The provision of this speaking device eliminates the device for hand signaling and aords an important degree of safety to a diver.
Another object of the invention is to provide an underl water speaking device which will not interfere in any way with the divers breathing.
Yet a further object is to provide an underwater speaking device which is light in weight and compact in size in order that it will not interfere with the divers actions.
An additional object is to provide a device of this nature which is rugged in design and simple of construction whereby it may afford a long and trouble-free service life.
It is yet another object of the invention to provide an underwater speaking device which is foolproof in operation having'no moving parts to get out of order.
Yet another object of the invention is to provide an underwater speaking device which may be readily installedy upon conventional underwater breathing apparatus.
Yet another object is to provide a device of the aforedescribed nature which may be manufactured at low cost so as to be available to a large market.
These and other objects and advantages of the presenty United States Patent O Referring to the drawings, the preferred form of undery water speaking device S is disclosed in conjunction with conventional self-contained underwater breathing apparatus B. The latter includes a mouth piece 10 which in Figure 1 is shown in position within the mouth of a diver D. The underwater breathing apparatus also includes ilexible, corrugated intake and exhaust hoses 12 and an air tank (not shown).
The mouthpiece 10 is of hollow construction and its front wall 14 is formed with a bore 16. The speaking device S includes a generally frusto-conical body 18 having a coaxial rearwardly extending neck 20. The neck 20 is formed with external threads 22. The mouthpiece bore 16 snugly receives the neck 20 and the latter is rigidly secured thereto by a nut element 24. A rubber sealing washer or gasket 26 is interposed between the front surface of the wall 14 and the rear surface of the 2,844,212 Patentedv July 22k, 1958 ICC cone portion 28 of the body 18. The body 18 will pref-i erably be of integral construction and may conveniently be molded of plastic. The large end of the cone 28 is located at the front of the body 18 and is open. A voice conducting passage 30 is coaxially formed through the neck 20.
As shown in Figure 2, the front portion of the cone 28 is formed with an annular rearwardly extending recess 32. A exible diaphragm 34 is rigidly maintained within the rear portion of this recess 32 by a protector element 36. The protector element 36 is formed with a plurality of apertures 38. The diaphragm 34 may be formed of any material which will readily undergo vibration under the influence of sound waves issuing from the divers mouth. Yet, the diaphragm must be suiciently rigid to withstand sub-surface pressures. Brass having a thickness of between .001 to .002 inch has beenfound to be suitable for this purpose. It is contemplated that pastic may also prove to be a suitable material from which to form the diaphragm. The protector 36 serves to prevent inadvertent damage to the diaphragm 34. This protector 36 may be formed of a plastic and it should be rigidly secured within the recess 32 as by a bondingV agent. The protector is formed over a major portion of its area with a plurality of sound-admitting apertures 38.
The operation of the speaking device embodying the present invention will be apparent from the foregoing description. When the diver D wishes to communicate K with another person the vibrations of his voice will effect concurrent vibrations of the diaphragm 34. l Such vibration of the diaphragm will create sound waves in the water of suicient intensity that they may be heard by a person located up to sixty feet away. It is also possible for persons located above the surface of the water to hear the divers voice.
While there has been shown and described hereinbefore what is presently considered to be the preferred embodiment of the present invention, it will be apparent that various modifications and changes may be made thereto without departing from the spirit of the invention or the scope of the following claim.
We claim:
An underwater speaking device for use with underwater breathing apparatus having a mouthpiece formed in its front portion With a bore, comprising: a generally frusto-conical body having its largest end open and formed with a rearwardly extending annular recess; a circular, flexible diaphragm disposed with the rear end of its recess; an annular protector having a rearwardly 'extending ange telescopically secured within said recess so as to retain said diaphragm therein, said protector having a water-tight connection with said body, and said protector being formed overa major portion of its area With a plurality of sound-admitting apertures; a neck coaxially extending rearwardly from said body for insertion within said bore, the rear portion of said neck being formed with external threads, and said neck being formed with a ycoaxial voice conducting passage; a nut element in said mouthpiece threadably engageable with said neck; and.
a rubber sealing washer encompassing the front portion of said neck between the front of said mouthpiece and the rear of said body. s
