HEARING AID ATTACHMENT Filed June l5, 1951 HEARING AID ATTACHMENT George W. French, Chicago, iii.

Application June 15, 1951, Serial No. 231,830 9 Claims. (Cl. 181-23) The present invention relates to a hearing aid attachmerit.

More particularly, the invention relates to a hearing aid attachment for use with a hearing aid device of the type wherein the output of a sound reproducer carried in a pocket, or in some place other than on an ear of a user, is connected to an ear of the user through a hollow tube.

Hearing aid devices of the above generally described type are well known in the art, and have come into widespread use because of the convenient manner in which they can be carried. Known devices of this type do have certain disadvantages, however, which prevent the device from being as completely satisfactory as they otherwise could be. In particular, known devices of this type utilize a small, hollow tube constructed of a semi-rigid material such as Lucite, aluminum, brass, etc., which is connected to an ear piece retained in the ear of the user, and is supported by being looped or fitted over an ear `of the user. Heretofore, the looped portions of the hollow tube have beenconstructed of metal or Lucite, and while satisfactory in operation have been the cause of some discomfort to the user due to the fact ythat such portions could not be easily shaped or fitted for a particular user, and because of this fact might be easily noticed while being worn. Further, should the particular portion of the tube in question be constructed of a semi-rigid plastic material such as Lucite, it might beeasly broken in the normal usage of the tube.

lIt is therefore one obiect of the present invention to provide ahearing aid attachment that can be readily fitted for a particular user.

Another object of the invention is to provide a hearing aid attachment of light, sturdy construction, that will stand up under considerable wear and tear and not be easily broken under normal conditions of usage.

Still another object ot the invention Y is to provide a hearing aid attachment that cannot be easily noticed while being worn.

Another object of the invention is to provide a hearing aid attachment that is relatively simple and inexpensive to manufacture.

A feature of the invention is the provision of a hearing aidattachment thatincludes an ear tip adapted to be fitted in the ear of a user, and a horrible, hollow tube for connecting the ear tip to a sound reproducer carried in the pocket of the user.

Another feature of the invention is the provision of a hearing aid attachment that comprises an ear tip, a iiexible, hollow tube for connecting the ear tip to a sound reproducer, the tube being readily formed into any desired shape, and means for retaining the tube in the desired shape.

Other objects, features, and many of the attendant advantages of this invention will be appreciated readily as vthe samebecomes understood by reference to the following ldetailed description when considered in rconnection with the accompanying drawing, wherein `'similar parts in each of the several figures are designated by the' same ffeie'ce numeral, and wherein:

Referring now to Fig. 1 of the drawings, the reference numeral 11 indicates an ear of an individual or user on whom the hearing aid attachment comprising the invention is fitted. Inserted in the ear of the user is an ear tip 12 which will be described more fully hereinafter. Connected to the ear tip 12 is a exible, hollow tube 13 which may be constructed of plastic such as Vinylite, rubber or some similar material which is sufficiently sturdy to retain its tubular character, but which is sufiicientlyresilient so that it can be readily formed into any desired configuration. The portion of tube 13 immediately adjacent ear tip 12 is formed into a U-shaped configuration and fitted over the ear of the user in the manner illustrated in Fig. l. ln the modification of the invention shown in Figs. 1 and 2, the tube 13 comprises a single unitary member. If desired, however, the tube may be formed in two pieces in the manner illustrated in Fig. 3 of the drawings, each of the separate pieces being constructed of the same material, and joined together by a tubular sleeve that serves to splice the two pieces of tubing together. The tubular sleeve is identical in construction to a sleeve, which is described hereinafter, that is used to connect the tube 13 to ear tip 12. Connected to the end of tube 13 opposite the end thereof to which the ear tip 12 is attached, is a means 14 for coupling the tube to the outlet of a sound reproducer, not shown.

With reference now to Figs. 2v and 3, the ear tip 12, which is preferably constructed in the manner described in my U. S. Letters Patent No. 2,545,731 issued March 20, 1951, comprises a generally cylindrical member having an intermediate portion thereof of lesser diameter than the end portions, and one of the end portions thereor rounded and shaped so as to be easily insertable in the ear of a user. The ear tip is made out of a hard plastic material, and has a passageway 15 formed therein for conveying sound waves therethrough from the hollow tube 13 to the ear of the user.

In order that the generally U-shaped portion of vt'ube 13 titted over the top of the ear of the user retain its desired shape, means are provided which are readily bendable, but which serves to maintain the shape of tube after the same has been fonncd into a desired Ushape configuration.

This means comprises a relatively tine, bendable element or wire 16, best seen in Fig. 5 of the drawings, which is sufficiently pliable so that it can be readily formed into a desired U-shape configuration, but which is suiiiciently strong to resist forces, other than directly 4applied forces, tending to deform the Wire once it has been shaped. For this reason the element lo preferably 'comprises a relatively tine strong steel wire which is lesser in diameter than the inside diameter of tube i3 and therefore adapted to be inserted in the tube. One end of the wire .i6 is outwardly hooked as at i7, and engages the side of a tubular sleeve i3, constructed of a rigid material such as aluminum, brass, steel, or any satisfactory substitute therefor, through which wire i6 extends in the manner best shown in Figs. 1l and 6. The tubular sieeve 1.8 is adapted to press tit in a generally circular portion i9 of a key-shaped aperture formed in ear tip 12 and comprising a part of the passageway 15, with the outwardly hooked portions i7 of the Wire 16 adapted to fit in a slot portion Zi? of the key-shaped aperture. in this manner, the bendable wire 16 may be secured to ear tip 12 and, if desired, tubular sleeve 1S may be glued in position. Upon completion of as sembly of the tubular sleeve i8, wire 5.6, and ear tip 1?., the iiexible, hollow tube i3 is drawn over wire 16 and sleeve i8 in the manner shown in Fig. 4 of the drawings, with the wire 16 extending within tube i3 for a portion of its length. if desired, the tube may be iirrniy secured to sleeve 18 by glue or some other adhesive, thereby forming a sturdy but light and relatively cheap hearing aid attachment capable of standing up under considerable use. Because the tube 13, sleeve i3, ear tip 12 may all be constructed of a clear plastic material, the attachment can be designed so that it is not easily noticed while being worn by a user. in the event that a two-piece tube 13 is provided, the lower portion of the tube can be readily changed should it become necessary because of hardening of the lower portion due to aging. Since it is desirable that the lower portion of the tube 13 be exible, this portion may then be renewed whenever it is necessary, and the upper U-shaped or ear portion retained thereby doing away with the necessity of reshaping the ear portion every time the lower portion of the tube has to be renewed.

With reference now to Figs. 7, 8, and 9 of the drawings, a second embodiment of the invention is illustrated which is, in many respects, identical to the embodiment shown in Figs. 2 through 6, but differs therefrom only with regard to the construction of the bendable element 16. In the embodiment of the invention shown in Figs. 7, 8, and 9, the bendable element i6 preferably comprises a wire having a reversely bent leg portion extending back towards the hook partion 17 iu a hairpin fashion. By constructing the wire i6 in this manner, all the advantages of the construction described in Figs. 2 through 6 are retained, and an additional advantage is obtained by the provision of the double leg portions of the wire which serve as a spacer to prevent the sides of tube 13 from being pressed together at any point along its lengt Referring now to Fig. of the drawings, the means whereby tube 13 is connected to the output of a sound reproducer is shown. This means comprises a hard plastic member 21 having a central passageway 2.2 formed therein for conveying sound Waves from the outlet of the reproducer to the interior of tube 13. For convenience, one end of the passageway Z2 is provided with a snap fastener 23 adapted to co-act with a complementaliy formed element on the outlet of the sound reproducer, and inserted in the opposite end of the passageway 22 is a tubular sleeve 24 constructed of aluminum or a similar rigid material over which the end of tube 13 is drawn and secured by gluing, or some other means. This construction provides a means for effectively connecting the attachment to the output of a sound reproducer without in any way complicating its manufacture.

.From the foregoing description it can be readily appre ciated that the invention provides an ear attachment that can be easily iitted on a particular user by merely shaping the portion of the flexible tube i3 through which bendable element or wire Ilo extends to iit over the top of the ear of the user. The wire 16 then serves to retain the tube in the desired shape. Because the wire 16 may be readily bent, this operation requires little or not time at all to perform, in contrast tothe considerable effort required shaping the semi-rigid plastic or metal tubes used on previous devices ot the same nature. Due to the fact that tube 13 is constructed ot a flexible material, it cannot be easily broken or chipped during normal usage, it is of light weight, and can be designed so that it is not easily noticed while being worn. Further, it is sturdy, simple to construct, and inexpensively manufactured. .i y

While the present invention has been described for use with a hearing aid device, it is of course to be understood that it may be readily adapted for use with any known sound reproducingrdevices such as a dictaphone, radio, telephone, etc., Without requiring any modification whatsoever.

Having thus described my invention, it is obviousthat various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement, and combination of parts herein shown and described, or Vuses mentioned.
