United States Patent i 2,816,620 AUDIO MODULATIN G AND CONTROL DEVICE Anthony J. Mosack, Gagetown, Mich. Application August 25, 1955, Serial No. 530,521 6 Claims. (Cl. 181-31) This invention relates to audio regulating devices as applied to television sets in general for controlling and directing the sound waves of the television set.

One of the prime objects of the invention is to design a sound directing fixture which can be easily and quickly attached to a television set, and which will direct and diffuse the sound waves emitted from the set, providing better sound reception and improving the synchronization of the sound with the picture.

Another object of the invention is to design a sound directing fixture provided with a tongue and fins, the tongue directing the sound waves toward the fins, which in turn dilfuse and modulate the sound waves as they are emitted from the set.

A further object is to design a television fixture which can be readily manufactured and assembled, and which can be mounted on television sets in the process of manufacture as well as on sets at present in general use, without the use of a tool, or the necessity for employing skilled labor for said mounting.

Still a further object is to provide a sound directing fixture of simple, practical and relatively inexpensive construction, which eliminates the undesirable harsh, tinny sounds, present in many sets, and which requires but a few minutes time to mount in position.

With the above and other objects in View, the present invention consists in the combination and arragement of parts, hereinafter more fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawings:

Fig. 1 is a side elevational view of my improved audio device.

Fig. 2 is a top plan view thereof.

Fig. 3 is a longitudinal sectional view taken on the line 3-3 of Fig. 2.

Fig. 4 is a perspective view looking into the mouth of the audio device.

Referring now more particularly to the drawing in which I have shown the preferred embodiment of my invention, the numeral indicates generally the housing of the device which can be formed of wood, plastic or any other suitable material. It comprises a pair of upwardly tapered side walls 1111, with an upper wall 12 formed integral therewith and forming a closure for the top, said top being curved downwardly as at 14 to form a closure for the restricted closed end, while the opposite end is open as at 15 to permit free flow of the sound waves emitted from the set.

A suitable bracket 16 is provided on the interior of the upper wall 12 directly adjacent the shallow restricted end thereof and a slit 17 is provided in said bracket to accommodate one end of a paper-thin tongue or reed 18, the free end of said tongue being spaced from the upper wall to allow it to vibrate with the sound waves and direct them outwardly as will be hereinafter more fully described, it being understood that the tongue does not come into contact with the walls of the device at any pomt.

2,816,620 Patented Dec. 17, 1957 An opening 19 is provided in the upper wall of the device as shown and is covered by a suitable flexible material 20 which mufiles undesirable sound waves and softens tones; thus persons sitting on the side at an acute angle from the mouth of the device will be able to distinctly hear the sound.

Spaced apart fins 21 are provided in the mouth or outlet end of the device and the free end of the tongue 18 ends directly adjacent the inner edge of said fins, said tongue waving the sound waves toward fins, diffusing the sound waves, modulating and providing better audio reception.

Spaced apart conventional suction cups 22 are provided on the lower edge of the side walls 11-11, the lower edge of said walls being spaced from the television set, as shown, these cups insulate the device from the set, and absorb and mute the tinny sounds usually characteristic of the lower-priced metal sets, table models, and others.

This device also moderates the harsh sounds when such sounds are emitted directly from the set, and it further controls, and directs the sound waves, making for better audio reception and control.

From the foregoing description it will be obvious that I have perfected a very simple, practical, and relatively inexpensive audio control device, which is economical to manufacture, simple and easy to mount, and which tends to better synchronize the picture and audio of television sets in general.

What I claim is:

1. An audio device of the class described comprising, an outwardly tapered fixture removably secured to a television set over the audio opening, said fixture comprising side walls and an outwardly tapered top wall, said tapered top wall forming also an end wall, the opposite end of said fixture being open to permit emission of the sound waves from the set and a paper-thin tongue mounted on the end wall with its free end projecting towards the open end of the fixture.

2. The combination defined in claim 1 in which an opening is provided in the top wall of said fixture to permit escape of the sound waves emitted from said set.

3. The combination defined in claim 1 in which spacedapart fins are disposed in the open end of said device.

4. An audio device of the class described comprising, a housing open at the bottom and one end only, said housing being tapered from its closed to its open end, a. paper-thin tongue mounted in the smaller end of the interior of the housing and projecting toward the open end thereof, and spaced apart fins provided in the open end forward of said tongue.

5. The combination set forth in claim 4 in which the outer free end of the tongue terminates at a point directly adjacent the inner edges of said fins.

6. An audio device for television sets comprising, a housing open at the bottom and one end only, said housing being outwardly tapered from its closed end, yieldable means secured to the side walls of the device for mounting it in position on a television set, a relatively thin tongue mounted in the interior of the closed end of the housing, and spaced apart fins disposed in the open end of the housing forwardly of the free end of said tongue.
