VIBRATION MODIFIER FOR DJiAPHRAGEJS Filed Jan. 22, 1925 Patented Get. 2,5, 192?.
JAMES G. NOLEN, OF NEW YORK, N. Y.
VIBRATION MODIFIER FOR DIAPHRAGMS.
Application filed January 22, 1925. Serial No. 3,977.
The present invention relates to tone modifiers for sound reproducing instruments, and particularly to a tone modifier preferably applied to a phone receiver, and one object of the invention is to provide a tone modifier which may be used in con junction with the diaphragm of the phone receiver, the invention in some respects being a modified application of the device Shown in my copending United States application Serial No. 755,213, filed Dec. 11, 1924.
One of the advantages of my present invention is that by its use there is caused to be formed adjacently to the diaphragm proper of the receiver a restrained air chamher. 'The advantage of this is that by re straining the air within a chamber formed by two .diaphragms, one of which is the phone receiver diaphragm, a form of tension is imposed upon the receiver diaphragm, thereby giving it greater sensitivity to the higher audio, frequency of oscillation, and through. this .tensioning causing the receiver diaphragm to be a livelier acting diaphragm.
Another advantage is. that due to the construction of my moclifier a small apertureis formed through which the pulsations of air from saidchamber may emit, and this therefore acts for. greater concentration of the tone vibrations as they issue from the opening.
Another advantage is the provision of simple means by which through modification of the vibration tensions upon the receiver diaphragm a modification of tone may be had, dueto the use'of a'baflle-likeivibration control means whereby the aperture or apertures through. which the sound emits may be varied to any desired degree Another advantage ofthe invention is that ,its'form of structure is such that it may be removably mounted in a phone receiver as desired. a
I attain the above object and such other objects as may later appear herein by the invention several of the many possible embodiments of which are described by way of example in the subjoined specification and shown inthe drawing accompanying. the
specification in which Fig. 1, is a fragmental side view, partly in section, of a phone receiver with the tone modifier applied thereto.
Figure 2, is a detail sectional view of one form of the tone modifier.
Figure 3, is a plan view of the form of tone modifier shown in Fig. 2.
Figure 4, is a detail sectional view of another form of the tone modifier;
Figure 5, is a detail plan View of the form of tone modifier shown in Fig. 4;.
Figure 6, is a detail sectional view of another form of the tone modifier.
Figure 7, is a detail plan view of the form of the tone modifier shown in Fig. 6, and
Figure 8, is a detail sectional view of an other form of the tone modifier.
Similar reference characters denote similar parts throughout the several views.
Referring to Fig. 1, there is shown a portion of a phone receiver having the cap 10 thereon provided with the sound opening 11 and the diaphragm 12 stretched across the sound opening and suitably spaced away from the adjacent under surface of the cap.
The tone modifier which is insertible in the openingll of the phone receiver, con: sists of the disk body 13 having the flange ltover which the marginal portion of the disk body extends and having the opening 15, and having supported in the disk body .the protector or protective disk 16 adapted to permit passage of air therethrough, and having supported in the disk body the modifier diaphragm 17 provided with the aperture 18. The protective disk 16 is retained in the disk body by the ring 19 and is spaced away thereby from the diaphragm 17, the diaphragm 17 being retained in the disk body by the ring 20 and spaced away thereby from the horizontal plane of the free end of the flange 14L of the disk body, a restrained air chamber 21 being formed between theupper surface of the phone receiver diaphragm 12 and the under surface of themodifier diaphragm 17 the air being emitted therefrom by the aperture 18 of the modifier diaphragm.
Referring to Figs. 2 and 3, the construction of the tone modifieristhe same as 100,
including I an ear fier diaphragm across said body spaced from 'near and parallel to the plane of the opening and over four times larger in diameter than the opening; a disk body inserted in the opening; and a modifier smaller than said opening disposed across said body.
5. In combination, a telephone receiver including an ear piece having a smallopeir ing therein; a disk body inserted in the opening; and a modifier diaphragm disposed across said. body.
6. In combination, a telephone receiver including an ear piece having an opening therein; 'a disk body' detachably disposed in the opening; and a modifier diaphragm across said body.
7. In combination, a telephone receiver including an ear piece having an opening therein, and a diaphragm near the opening; a disk body in the opening having a flange received and frictionally held in said opening; and a modifier diaphragm across said body.
8. In combination, a telephone receiver piece having an opening therein; a diaphragm protector disposed across said opening; and a modifier diaphragm across said opening below said top protector.
9. In combination, a telephone receiver including an ear piece having an opening therein; and a silk modifier diaphragm acrosssaid opening.
10. In combination, a telephone receiver including an ear piece having a small central opening therein, and a diaphragm near the opening; a disk body in the opening having a protecting top wall with an aperture having a flange received in said opening; and a silk modifier diaphragm across said body spaced from said top wall and provided with a small aperture therein.
11. In combination, a telephone receiver including an ear piece having an opening therein; a disk body across the opening hav-- ing a top diaphragm protector substantially out of contact with'the ear in normal use;
and a modifier diaphragm across said body below said protector.
12. In combination, a telephone receiver including an ear piece having a small central-opening therein, and a diaphragm near the opening; a disk body in the opening substantially out of reach of the ear in normal use; and a modifier diaphragm across said body.
13. In combination, a telephone receiver including an ear piece having an opening therein; a modifier diaphragm across said opening and provided with an aperture; and a battle alined with said aperture.
14. In combination, a telephone receiver including an ear piece having an opening therein; a disk body in the opening having a top wall with an aperture therein; and a modifier diaphragm across said body below said top wall and provided with an aperture.
15. In combination, a telephone receiver including anear piece having an opening therein; a disk body in the opening having a top wall with an aperture therein; zind a modifier diaphragm .across said body below said top wall and provided with an aperture out of alinement with the aperture of the top wall.
16. In combination, a telephone receiver including an earpiece having an, opening therein; a disk body about the size of said opening and inserted in the opening in a position substantially out of reach of the ear and having a top wall entirely across the body provided with apertures remote from the center of the body and having a flange received in and detachably frictionally held in said opening and provided with an outwardly faced annular shoulder on its inner face in a plane near and parallel to said top wall; and modifier diaphragm disposed across said body spaced from and protected by said top wall and provided with a central aperture out of alinement with the aperture of the top wall and plate whereby said top wall between the apertures thereof acts as a baffle.
17. In combination, a telephone receiver including an ear piece having an opening therein; a disk body in the opening having a top wall with an aperture therein of adjustable size; and a modifier diaphragm across said body below said top wall.
18. In combination, a telephone receiver including an ear piece having an opening therein; a disk body about the size of said opening and inserted in the opening and having'a top wall entirely across the body provided with apertures remote from the center of the body and having an inner flange received in and detachably frictionally held in said opening and provided on its inner face with an outwardly faced annular shoulder in a plane near and parallel to, said top wall; a top plate rotatably mounted on the top wall in a position substantially out of reach of the ear and having apertures registerable with the apert-ures of the top wall; and a modifier diaphragm across said body below said top wall.
19. In combination, a telephone receiver including an ear piece having an opening therein, and a diaphragm near the opening;
