ELECTRI CAL HEARING AID Filed June 29. 1961 United States Patent 3,209,080 ELECTRICAL HEARHNG All) Werner Giittner and Clemens Starke, Erlangen, and Franz Sapara, Erlangen-llruclr, Germany, assignors to Siemens-Reiniger-Werke Aktiengesellschaft, Erlangen, Germany, a corporation of Germany Filed .lnne 29, 1961, Ser. No. 120,640 Claims priority, application'Germany, May 12, 1961, S 73,924 7 Claims. (Cl. 179-107) This invention is concerned with an electrical hearing aid to be worn in back of the ear, comprising a housing containing electrical components including the microphone, amplifier with regulating elements, battery and receiver, and having a hookshaped carrier portion which is free of electrical components, preferably removably connected with the housing and attachable to the upper part of the auricle.
The housing of a hearing aid which is worn in this manner, is thus positioned in back of the ear while the carrier portion extends toward the front of the ear. Accordingly, the microphone, which is disposed in the housing, is at a place lying in back of the ear. The entry or inlet opening through which the sound comes to the microphone is thereby provided as close as possible to the microphone, that is, at a-place of the housing which is in back of the ear below and remote from the hooklike carrier. The sound inlet opening, also referred to as the speak-in opening, is thus frontally largely shielded by the auricle and also by the head. This is a disadvantage because sound waves generated in the course of a conversation come to the person who is hard of hearing, from the front and can be received and amplified only along a detour over a path extending in back of the ear.
The invention provides a hearing aid of the initially indicated kind, comprising means forming a sound-conducting line extending contiguous to the sound entry element of the microphone provided in the housing, such line extending to the end of the housing facing the carrier part and continuing in the carrier part or approximately parallel thereto to a microphone sound supply line which terminates in a preferably frontally visible sound inlet opening. This makes it possible that sound waves coming directly from the front can reach the microphone without going over a detour. The person hard of hearing is thus, with the use of the hearing aid according to the invention, in a better position to follow speech which a conversation partner directs at him from the front.
The hearing aid according to the invention comprises, in an exemplary embodiment, a carrier which contains in known manner an acoustic passageway forming the sound exit channel extending from the receiver to the ear piece. In addition, this carrier contains an acoustic passageway forming the sound inlet channel extending to the microphone, such latter channel terminating in the region of the greatest curvature in a frontally visible opening of the convex wall of the carrier. The carrier which is constructed in this manner is advantageously plugged to tubular studs extending respectively from the receiver sound exit line and the microphone sound inlet line forming parts of the housing. The fastening of the carrier on the housing is effected by means of an extension which may be screw connected to the housing.
The receiver is advantageously disposed in the housing about midway of the longitudinal extent thereof and the sound exit line to the ear piece is carried past a narrow side of the microphone which is positioned ahead of the receiver. The sound exit line extending from the receiver is formed by a tubular part which is flattened at least at the portion thereof which passes along the microphone.
The flattened portion of this tubular part is thereby positioned in parallel with the narrow side of the microphone, thus providing for a space saving disposition of the sound exit line.
The various objects and features of the invention will appear from the description which will be rendered below with reference to the accompanying drawing showing in perspective representation and in sectional views examples of details of hearing aids constructed according to the invention.
FIG. 1 shows an embodiment of the hearing aid in perspective view;
FIG. 2 shows the housing with the therefrom;
FIGS. 2a and 2b show sectional views taken respectively along lines Ila-Ila and IIbIIb in FIG. 2;
FIG. 3 shows the carrier part of the hearing aid illustrated in FIG. 1;
FIG. 4 shows in perspective view an embodiment of a hearing aid wherein the carrier is made of two parts, one part containing only the sound exit line extending from the receiver to the ear piece, while the other part contains the sound inlet line extending to the microphone; and
FIG. 5 shows a hearing aid made in accordance with the invention in its position in connection with the ear.
The acurately shaped housing 1 which is made of synthetic material is constructed of two shells 2 and 3. The housing contains a drawer 4 for receiving the battery,
cover detached such drawer being pivotally journalled at 14 and being provided with a handle 5. From the convex outer wall of the housing extends part of the sound volume adjusting member 6. At the end of the housing 1 opposite the pivoted drawer 4 is disposed the carrier 7 which is curved hooklike and has an extension 8 provided with a hole formedtherein (FIG. 3) through which a screw is projected for firmly fastening the carrier to the housing. The carrier terminates in a nipple 10 (FIG. 3) to which is attached a flexible hose 11 carrying an angular member 12 which in turn carries the flexible ear piece 13 to be inserted into the aural opening of the ear.
FIG. 2 shows the shell 2 of the housing with the component parts as they become visible after removal of the shell 3 and detachment therefrom of the carrier 7. Adjacent the battery drawer 4 is a partition 15 carrying the contact spring 4a, followed by the receiver 16 which is wrapped in foam rubber 17 (FIG. 2b). Next to the receiver 16 and partially thereunder are disposed parts of the amplifier 18. The amplifier parts, including also the volume control with the regulator 6, are mounted on a bracket 19. Below the bracket 19, and fastened thereto, are positioned capacitors and resistors which are schematically indicated respectively at 20 and 21, and at the portion of the bracket 19 which is next to the telephone 16, are positioned transistors 22 (FIG. 2b). Next to a partition 23, which delimits the amplifier space, is disposed the microphone 24 which is wrapped in foam rubber 25.
From the microphone 24 extends an acoustic passageway or sound inlet line 26 terminating in a tubular part 27 which projects from the housing. From the receiver 16 extends an acoustic passageway or sound exit line 29 which terminates in a tubular part 28, the latter likewise projecting from the housing. The sound exit line 29 which extends from the receiver 16 to the tubular member 28 is of oval cross-section at the portion thereof which passes along the microphone 24 (see FIG. 2a). The carrier 7 through which extend the sound channels 30 and 31, as shown in FIG. 3, is plugged to the tubular connecting members 27 and 28. The sound exit channel 30 extends to the nipple 10 to which is connected the flexible hose 11 leading to the ear piece 13, and the sound inlet channel 31 (for the microphone 24) terminates in the sound inlet opening 32.
The hearing aid illustrated in FIG. 4 corresponds substantially to the hearing aid described with reference to FIGS. 1 to 3. The only difference resides in the construction of the carrier, indicated in FIGS. 1 and 3 at 7, which in FIG. 4 is made in two parts, one part 33 containing only the sound exit channel 34 leading from the receiver 36 to the ear piece 37. The sound inlet channel 38 leading to the microphone 39 extends through the other part 40 Which is fastened to the housing 35 by means of an extension 41. The part 40 can also be constructed as a tube which is screw connected with the connecting tube 27 (FIGS. 2 and 2b), it being of course assumed that appropriate threads are provided for this purpose.
As will be seen from FIG. 5, the housing (1 in FIG. 1 or 35 in FIG. 4) is in operation positioned in back of the ear 42 while the carrier 7 (33, 40 in FIG. 4) extends forwardly of the ear 42. The sound inlet opening 32 (opening of inlet channel 38 in FIG. 4) thus comes to lie at a point which is in the use of the hearing aid directed toward the front. Sound waves directed toward the person wearing the hearing aid can accordingly directly enter at the sound inlet opening such as 32 for direct propagation without any detour, to the microphone 24 over the lines 31 and 26 (FIGS. 2 and 3) or to the microphone 39 over the line 38 (FIG. 4). The microphone converts the sound waves into electrical signals which are amplified in the amplifier such as 18 (FIG. 2) and made audible again in the receiver such as 16 in FIG. 2 or 36 in FIG. 4. The amplified sound waves are in FIGS. 13 conducted to the aural passage of the ear 42 over the line 29, channels 30, 11, and through the ear piece 13, while being in FIG. 4 conducted to the aural passage over the lines 34 and the ear piece 37.
Changes may be made within the scope and spirit of the appended claims which define what is believed to be new and desired to have protected by Letters Patent.
