O. BYRON SOUND RECEIVER EARPIECE Filed Aug. 5, 1922 Patented Apr. 8, 1924.
UNITED STATES OSCAR BYRON, OF JERSEY CITY, NEW JERSEY.
Application filed August 3, 1922. Serial No. 579,437.
1 '0 all 101mm it may concern:
Be it known that I, OSCAR BYRON, a citizen of the United States, and residing at 507 Summit Avenue, Jersey City, in the improvement is directed particularly to an ear contacting member which is capable of application directly to the ear of the user in a manner to exclude all external noise and vibration; also to enable the device to be pplied and worn with a maximum of comort.
With the head pieces of receiving sets now in use either low efficiency in external sound exclusion exists or else the pressure exerted to provide snugly ear enclosing means, whether applied to the ear or to the head around the ear, involves considerable discomfort through protracted usage; and it is an object of my invention. to rovide means for the remedy of this condltion.
Therefore my invention consists in the use of a pad of soft, resilient material such as spongy rubber, which can be applied con tactingly against the ear under moderate pressure, so as to mould or embed the irregular contour of the ear into the substance of the pad; and in providing the pad with an orifice therethrough, for communication with the auditory canal of the ear.
The pad may be suitably connected to a sound receiver, and in one form of-my invention it is provided with means whereby it is capable of removable engagement with a receiver.
Other features and advantages of my invention will hereinafter appear.
In the drawing ,Figure 1 is a cross sectional view of my improved device, showing it as fitted upon a sound receiver and as applied to a human ear.
Iiig. 2 is a front elevation of the device,
Fig. 3 is a section on the line 33 of Fi 2.
n carrying out my invention I prepare a block or iece of porous or spongy material, such as spongy rubber, which has a normally set structural form but is also of resilient or yieldable character so that under the application of slight pressure will yield to embed therein any object having a more rigid structure.
This block indicated in the drawing by the reference numeral 1, is there shown to have a uniform thickness of a sufficient degree to enable it to serve the purpose of my in vention, which purpose is that the block will contactingly overlay a human ear, and, under pressure, absorb within its yielding substance, by embedment at its surface 2, the characteristic ear features, such as the tragus, antitragus and antihelix, thereby effectually closing entrance, between the block and the ear, to the auditory canal.
The block 1 is rovided with an aperture 3 that extends t erethrough axially with relation to the auditory canal of the ear, when applied; and this aperture, as shown, is directed toward the entrance to them;- ditory canal, for the better directional conveyance of sound waves toward the tympanum. 1
Upon the opposite, or outer surface 4 of block '1, I secure, as by cementing, or otherwise, a flexible cap or'hood 5, which is provided with a central 0 ening 6. This hood is composed of elastic material, like soft rubber, to be capable of stretching so that its opening 6 may be enlarged to fit snugly over a sound receiver 7, to keep out external noises, and restrict the communica tion of sound to the ear solely through the aperture 3.
The receiver 7 is here shown as forming part of a head piece 8 to illustrate one of the various manners in which the block 1 may be applied with pressure contactingly against the ear.
I Variations within the spirit and scope of my invention are equally comprehended by the foregoing disclosure.
I claim 1. An ear pad for sound'receivers consisting of a. block of resilient, porous material to lie mouldably against the ear, said block provided with an aperture therethrough for communication with the auditory canal, and a cap of stretchable material secured to said block for removably fitting upon a sound receiver.
2. An ear pad for sound receivers consisting of resilient very soft and yielding material having a substantially flat outer face whereby said face may-be pressed against the ear and the material yield to conform to and fill the convolutions of the ear, and having a sound conducting aperture for con'imunication with the auditory canal.
3. An ear pad for sound receivers comprising a body member of resilient very soft and yieldable material having a substantially flat outer face, whereby said face,
may be pressed against the ear and the material yield to conform to and fill the convolutions and irre ular surface of the ear, and having a sound conducting aperture for communication with the auditory canal, and means for securing said body member to a sound receiver.
