My invention relates to sound reproducing devices and especially to those devices which are used to augment or amplify the sounds which are being reproduced from a record.

JOHN C. ENGLISH, OF CAMDEN, NEW JERSEY, ASSIGNOR TO VICTOR TALKING COMPANY, A CORPORATION OF NEW JERSEY.

SOUND-REPROD'UCING DEVICE.

Specification of Letters Patent.

Patented Jan. 25, 1910.

Application filed July 19, 1906. Serial No. 326,827.

To all whom it may concern:

Be it known that I, JOHN G. ENGLISH, a citizen of the United States, and a resident of Camden, State of New Jersey, have invented certain new and useful Improvements in Sound-Reproducing Devices, of which the following is a full, complete, and exact disclosure.

My invention relates to sound reproducing devices and especially to those devices which are used to augment or amplify the sounds which are being reproduced from a record.

The object of my invention is to dispense with the ordinary megaphone, sound amplifying-trumpet, or horn which is usually used to amplify the sounds reproduced by talking machines, and to increase the volume of the tones by means of an amplifier having sound boards which are caused to vibrate in sympathy with the vibration of the air conducted between the same from the sound conveying tube.

A further object of my invention is to convey the vibrations from the reproducer to the sound amplifying device without loss,

and then to allow the said vibrations to emerge between the sound boards of the amplifier.

A further object of my invention is to support the amplifier at one end only so that the sound boards may be free to respond to the vibrations imparted to them from the sound reproducer.

A further object of my invention is to make the sound boards used in connection with my sound amplifying device resonant in order to cause the same to readily vibrate in sympathy with the air inclosed between the same.

Other objects of my invention will appear in the specification and claims below.

In the accompanying drawings forming a part of this specification, in which similar parts are referred to by the same reference characters, Figure 1 illustrates a sound reproducing device provided with my improved sound amplifier, the main portions of the same being shown in cross section; Fig. 2 is a perspective view of my improved sound augmenting device; Fig. 3 is a diagrammatic view showing the method employed by me to make the sound boards of the sound amplifying device resonant, and Fig. 4 is a view similar to Fig. 3 showing the method of .of'the major portion 0 constructing the inner sides of my improved device. 7

Referring to the drawings, one embodiment of this invention comprises a casing or talking machine cabinet 1 upon the top of which is the housing 2, which contains the turntable 3, the reproducer 4 and the swinging arm 5. The larger end of the tapering swinging reproducer arm 5 is pivoted as at 6 to a hollow bushing 7 which communicates with the smaller end 8 of a hollow bracket, or elbow 9, the opposite end of which is adapted to support my sound amplifying device 10.

The bracket 9 or sound conductor consists of a rigid hollow structure, curved longi tudinally through an arc of about 90 degrees, the smaller end of which is provided with a plate 11 integral therewith by which the same is rigidly secured by means of screws 14: to the thick partition 12 which supports the talking machine motor 13. The smaller end of the opening in this bracket is substantially circular in cross section and registers with the circular opening in the bushing 7 and, from the point of connection between the bushing and the bracket, this bracket increases in size and terminates in anenlarged rectangular oblong outwardly flaring socket 15. The opening through the bracket also increases in transverse sectional area downwardly and gradually changes in shape from circular at its upper end, to the oblong shape of the socket at its lower end. I make this bracket 9 very rigid,. so that the same will not be set into vibration by the sounds conveyed therethrough, by rigidly securing the same to the thick top 12 of the cabinet, and

by bracing the same by webs 16, 17 at the front and back sides of the same respec-.

tively. If desired, the bracket may be made of such proportions that the bracing is unnecessary to prevent the vibration of the same. I preferably make the bracket ,8 of metal, since a metal bracket may be made 'sufiiciently rigid for my purposes, but any material may be employed by me so long as the same will resist the tendency to vibrate in sympathy with the vibrations of the air contained thereinv and support the sound boards;

Within the veying bracket 9, I sup ort the smaller end my sound amplifylarger end of the sound con-' from their point I amplifying ingdevice, the same consisting of a hollow flattened taperin body 10, having resonant wooden sides. 'Iie top and

bottom sides

18 and 19 of this body, aretmade of thin resonant substantially flat wooden boards, the outer edges of which overlap and are secured in any suitable manner to the edges of vertically arranged substantially fiat wooden su orting boards 20, 21.

0 top and

bottom sound boards

18, 19 are spaced apart from each other and may be substantially parallel, or may diver e of attachment with t e rigid bracket-9, but the vertical sides of the resonant 'body preferably diverge considerably, the outer ends of the same being spaced apart nearly the full width of the talking machine cabinet. a

While the four sides of the body of the device, may be made thin and resonant, refer to make the upper and 1 lower sound cards, 18, 19, of thin resonant material, and the sides 20, 21 of thick and comparatively non-resonant material.

To give a pleasing resonant quality to the upper and lower sound boards 18, 19-, I construct the same in the manner indicated in- Fig. 3; thatis to say, I build up and glue together aseries of boards 22, so that the sound board which is to be formed from the same will cross the lines upon which the boards 22 are glued together 'at an acute angle, as plainl shown in said Fig. 3. I then saw or ot erwise cut out of the series of boards 22 glued together, the

sound boards

19 or 20, as the case may be, with the result that the finished sound boards are composed of a lurality of sections of wood, cut parallel to the grain, the said pieces belng glued together for a considerable distance, notwithstanding the fact that the finished sound board is very thin. As plainly shown in all the figures and as above described, the sound boards may be described as bein composed of a structure composed of "uIastantlally overlappin scarfed wooden strips, the direction 0 the grain thereof, being transverse to the length of the resonator.

If desired, I may make the sides 20, 21 of wooden strips similar to the

sides

18, 19, as plainly shown in Fig. 4, although the'sides 20, 21 may be thick and non-resonant as above described.

I have found that a sound amplifying device constructed and arranged 1n the manner above described, eflects a loud and mellow, but brilliant reproduction of the sound, in addition to taking-up less space than that which is'ordinarily required in the amplifyin' horns usually employed in connection.

upper and lower sound boards are nearly parallel, will-effect as loud a reproduction of the sound as a megaphone or an ordinary tapering horn 12 inches across the bell thereof, and that the sound reproduced is of a much more pleasing quality than that from I a born or megaphone of the ordinary type above referred to. m

The sound waves set into vibration by the reproducer are transmitted through the rigid swinging sound conveying tube 5 and through the rigid bracket 9, out and between i the thin resonant sound boards of my imroved sound amplifying device, these oards being set into sympathetic vibration with and by the waves being conducted .therethrough and by the vibration of these sound boards, the sounds corresponding to the vibrations being reproduced, are greatly augmented or amplified. By thus using in' the talking machine an amplifier comprisin a tapering longitudinally curved rigid bracket having an openin therethrough which is substantially circu ar at its inlet end and oblong at its outlet end which opens between the transversely oblong body portion of the amplifier, it is possible to convey the sound waves from the sound box to the resonant body of the amplifier without loss of energy, and to utilize, with a high degree of efliclency, comparatively broad sound boards, without taking up much space vertically in the cabinet of the machine. By making the bod of the amplifier oblong and comparatively road horizontally but narrow vertically, it is thought that a desirable quality is obtained in reproducing sound.

Although only one form has been herein illustrated in which this invention may be embodied, it is obvious that many changes may be made in the construction shown without departing from the spirit of the invention or the scope of the appended claims.

Havin thus described my invention, what I c aim and desire to protect by Letters Patent of the United States is 1. In a talking machine, the combination with a vertical cabinet, of a hollow, longitudinally curved rigid support rigidly sesupport and communicating therewith, and
