Specification of Letters Patent.
Patented Feb. 28, 1922.
Application filed October 21, 1920. Serial No. 418,415.
To all whom it; may: concern:
Be it known that I, Glnsnrrn VIRZI, a subject of the King of Italy, but having declared, my intention of becominga citizen of the United States. and residing at 3&1 East 124th Street. New York city, in the county of New York and State of New York. have invented certain new and useful Improvements in Sound-Producing Instruments, of which the following is a specification.
This invention relates to sound producing instruments and has particular reference to means for increasing the force or resonance of the tones produced thereby.
The spirit of this invention may be carried out in many ways, but I have illustratcd in the accompanying drawings and whereon similar reference characters are applied to corresponding parts of different views, the invention applied totalking ma chine reproducers and of which drawings- .Fig. 1 is a vertical sectional view of a reproducer head of a talking machine showing my invention.
Fig. 2 is a front elevation of the same.
I illustrate a talking machine sound box 17 having secured within its rim 18 a vibratory body or diaphragm 19 of any suitable construction, the periphery of the diaphragm being gripped between resilient gaskets 20.
At 211 indicate astylus bar connected in any suitable manner to the lower portion of the sound box and adapted for oscillation toward and from the plane of the diaphragm 19 as is well understood. Differing from the usual stylus bar, however, this one is provided with a plurality of fingers 22 and 23. The linger 23 is shown as projectingthrough the center of the diaphragm l9, and it may be secured to the dia 'ihragm 19 by any suit able means such as wax or glue.
Associated with the main diaphragm 19 are one or more auxiliary sound producing means shown as diaphragms 24; and 25 spaced from one another and from the main diaphragm and on either the inside or the outside of the box. As shown the auxiliary diaphragms or sound transmitters are arranged one on the inside of the; box and the other on the outs de. The edges or per1ph= from the movable member.
cries of the auxiliary diaphragms are free or spaced from all other structure.
The finger 23 extends through all of the diaphragms and in connection with a washer 2G constitutes the sole support for the innermost diaphragm 2st. The fingers 99 are attached to the outermost diaphragm and constitute the means for supporting it. in connection with the center finger 23. The (liapl'iragms are all so constructed or designed s to harmonize with one another so that the tone vibrations imparted thereto or transmitted therethrough will either be in unison or in harmony, in order toproduce the most satisfactory and pleasing rendition of the tone. FllltllQlIllOlQ, the several auxiliary diaphragn'is must be so designed as to take account of the different means for supporting them.
claim:
1. In a sound producing instrument, the combination of a main vibratory-member, a movable member connected to the vi? bratory member to cause the vibration thereof, a second vibratory member adjacent to the main vibratory member, the connecting means between the main member and the movable member extending through the second mentioned vibratory member, and means auxiliary to said connecting means to sup port the second vibratory member.
2. In ,a sound producing instrument, the combination of a main diaphragm, movable means to cause the vibration thereof, an auxiliary diaphragm, and other sound producing means adjacent to but spaced from the main diaphragm, said movable means including a member connected to both diaphragms and also to said other sound amplifying means. l
3. A device as set forth in claim 2 in which the connecting means between the movable member and the diaphragms consists of a finger extending through the centers of the diaphragms.
t. A device asset forth in claim 2 in which the auxiliary diaphragm is located on the opposite side of the main diaphragm 5. In a. sound producing instrument, the combination of a sound box including a main diaphragm, a movable member on the outside of the diphragm but connectedtherewith to cause vibrationthereof, an auxiliary which a second auxiliary diaphragm is provided and loated oh the other side of the Inain-diaphragm'from the first mentioned auxiliary diaphragm, and means are providedto co-operate with the movable Inemher and supporting means mentioned to cause all three cliaphragms to vibrate at the same time sub stantiall as set forth.
