COMBINED SOUND-REPRODUCER AND LIGHTING-FIXTURE.
Specification of Letters Patent.
Patented July 16, 1918.
Application filed December 17, 1914. Serial No. 877,802.
To all whom it may concern:
Be it known that I, HERMAN Gr. PAPE, a citizen of the United States, and resident of New York, in the county of New York and State of N ewYork, have invented a certain new and useful Combined Sound-Reproducer and Lighting-Fixture, of which the following is a specification.
My invention relates particularly to compact stentoric or megaphonic apparatus combined with lighting and sound reproducing apparatus, and adapted for use in auditoriums, churches, theaters, railroad depots, offices, homes, sitting rooms and other situa tions in which sound reproducing and amplifying devices may be employed to enable an individual, or individuals or an audience to hear operatic, or musical reproductions, addresses or other sounds which may be electrically transmitted to the reproducer from some other place.
In accordance with my invention the sound reproducers and amplifiers may be combined with chandeliers or other lighting fixtures supported from the ceiling or walls, and the ceiling and the light reflectors may also serve as sound reflectors. The sound reproducers as well as the lights may be hi dden by certain reflectors from the view of the audience. It will thus be seen that the invention provides an arrangement whereby the need of reflectors and other fixtures for the sound reproducers is dispensed with, the lighting fixtures in addition to their usual functions serving as supports and reflectors for the sound reproducers, and the ceiling, arch or dome structure of the room, auditorium, or compartment, serves not only as a diffused lighting deflector, but also as a diffused sound deflector.
The invention further provides an improved sound amplifying device inwhich the sound by a multiple reflection and expansion is magnified to a state of distinct audibility and shot out either with great force, or greatly increased in volume, or both, according to its spread or choke construction. This device may also be used as a sound collector or concentrator. It is very compact and pleasing in contour, adapting it for use in compact and elaborate places.
Another feature of the invention is the provision of an improved form of sound rcproducer in which the electromagnet comprises a cylindrical magnet shell having a central core, a coil mountedon said core, a
washer surrounding the core and holding the coil in position and a screw of magnetic material threaded into the end of the core and serving the double function of holding the washer and coil in place and also increasing the area of the pole face opposed to the diaphragm.
Other features and advantages will appear hereinafter. In the accompanying drawings,l*igure l is a sectional elevation view of a combined lighting and sound reproducing apparatus constructed in accordance with the principles of my invention. Fig. 2 is an elevation view of a modified construction, parts being broken away to show the apparatus. Fig. 3 is a sectional view on a larger scale of my sound mortar, or sound reproducing and amplifying device. Fig. a is an elevatron view of a modified form of chandelier or lighting fixture comprising a group of lighting and sound reproducing elements.
In the combined lighting and sound rcproducing and amplifying apparatus shown in Fig. 1, electric lamps 1 are supported above a reflector 2 suspended by means of rods 3 from a support 4 attached to the ceiling 5. The reflector 2 which may be made of any suitable material either opaque, or translucent, hides the lamps from the view of persons in the room and screens them from the direct rays of light, the light being reflected on the ceiling which may be in the. form of a concave reflecting surface 6 by which the light is reflected and diflused through the room.
In combination with the lighting apparatus is a sound reproducing and amplifying device comprising an electrical sound reproducer '7 and a sound amplifier 8. Referring particularly to Fig. 3, the sound reproducer '7 comprises an clectromagnet consisting of cylindrical shell. 9 of magnetic material having a central core 10 and magnet coil 11 within the shell 9. The coil 11 is held in position within the magnet shell by a washer or disk 12 of non-magnetic material, said washer surrounding the core 10 and held in position by a screw 1.3 threaded into the core 10. Said screw is made of magnetic material, and the head of the screw being of a greater diameter than the core 10 forms an enlarged pole face as well as holding the washer 12 and the magnet coil in position. The upper end of the magnet shell is threaded at 14 into a correspondingly threaded opening in the casing 15. A diaphragm 16 extending cross the lower face of the casing 15 is secured to the casing by means of a ring 17 which may have a screw threaded connection with the casing.
The terminals 18, (Fig. l) of the magnet coil may be connected through suitable conductors to an ordinary telephone transmitter or other instrument for converting sound into electrical impulses which in the reproducer (Fig. 3) set up vibrations in the magnetic diaphragm 16 and reproduce the sounds in a well understood manner.
The volume of the sounds is greatly increased by the amplifier 8 to which the magnet casing 15 is secured as by means of screws 19. The sound waves are transmitted through a funnel 20 by means of which they are expanded and then reflected on the concave surface 21 of an inner bell or deflector 22, the latter being secured as by means of a bracket 2-3 within an outer shell 24s. The sound reflected on the concave surface 21 is further expanded as it passes upward and strikes the concave surface 25 of the outer bell 24 and is deflected downward through the open'mouth of the bell, being further expanded in its downward passage through the bell 24:. The sound waves being expanded during their passage through the funnel 20, the deflector 22, and the bell 24, the volume is greatly increased. The sound waves emerging from the bell 2%, Fig. 1, strike the upper surface of the reflector 2 and are reflected upward to the ceiling and then reflected and diffused through the room;
Fig. 2 shows a modified arrangement in which a reflector 26 is suspended by means of a chain 27 from a support l. The sound reproducer and amplifier 8 are in this arrangement inverted as compared with Fig. l sothat the sound waves are projected upward therefrom and striking the reflector 26 are deflected downward through the room. An inverted bell or reflector 28 may form a support for the sound'reproducing means as well as for electric or other lights contained therein. The reflector 26 serves to deflect thelight as well as the sound wves.
Fig. 4 shows a chandelier or lighting turecomprising a base 30 from which are suspended by means of chains 31 a group of bells or reflectors 32 which may contain incandescent or other lamps. The bells 32 may alternate with sound reproducers 7 also suspended from the base 30 and which may beat a somewhat higher level than the lighting element 32 to assist diffusion of the sounds, avoid crowding and to produce a more convenient and artistic arrangement. It will be noted that with the arrangement shown'in this view the sound may be thrown directly downward through the room from the amplifiers 8. Electric lamps may, if desired be placed directly within the amplifiers 8.
Various other modifications than those herein disclosed may be resorted to within the scope of the invention, and parts of the invention may be used without others.
