- the bend at 14 is of great importance in connection with the present invention, inasmuch as due to this bend, at least the lower portion of the longer lower part of lever 11 will closely and snugly engage the mastoid bone of the wearer of the ear set when the latter is in its position of use. As a result thereof, the outer housing surface 7a is urged closely against the ear of the wearer and will be given the desired close fit on the ear.
- a high satisfactory angle by which the surface section 14a is offset from 14b would be, for instance, an angle of from 3 to 10, but it is to be understood that this angle could also be somewhat less or more.
- the lever portion downwardly from the line where the bend occurs must at least approximately follow the contour of the mastoid bond or head portion behind the respective ear so that while resting thereagainst, the lever surface section 140 will urge the housing close to the ear of the wearer. Since the mastoid bones on opposite sides of the head slant in opposite directions, it will be evident that the ear set according to the invention made to be worn over the left car must not be worn over the right ear and vice versa.

10 Claims, 9 Drawing Figures Patented Jan; 21, 1975 EAR SET The present invention relates to ear sets with miniaturized electronic sound receiving and emitting equipment. Ear sets of this general type which are hooked over an ear have been known for some time and substantially comprise a two part housing hook section, the two parts of which, respectively form a single integral part with the two parts of said housing section so that one part of the housing section forms a single integral rigid piece with one part of the housing, and the other part of the housing section forms a single integral rigid piece with the other part of the hook section. Ear sets of this design have not been adopted in practice to any material extent primarily because they do not adapt themselves closely and properly to the average ear variations and ear bone, or mastoid bone configurations and, therefore, have not the required close fit and drop off easily from the ear.
It is, therefore, an object of the present invention to provide an ear set of the above mentioned general character, which will overcome the above outlined drawbacks and will easily and automatically adapt itself to any ear and mastoid bone structure of the respective wearer of the ear set so that it will be safely held on the respective ear.
It is still another object of this invention to provide an ear set as set forth in the preceding paragraph, which will permit electronically to use not only the housing section, but also the hook section and can be used even under high ambient noise conditions, e.g., by pilots in an airplane cabin, by telephone operators in telephone companies, etc.
These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawing, in which:
FIG. 1 illustrates an ear set according to the invention with mouth tube and ear set cord.
FIG. 2 shows on an enlarged scale, that side of an ear set according to the invention which, when the set is mounted on the ear, points away from the ear, the lever or ear hook portion of the ear set being shown in two different positions in full lines and dash lines respectively.
FIG. 3 shows the ear set of FIG. 2, but seen from the opposite side with a portion of one section of the ear hook broken away.
FIG. 4 is an end view of the ear set according to the invention as seen along the line lVlV of FIG. 2.
FIG. 5 is a cross section through the double purpose joint between the housing of the ear set and the lever thereof, said section being taken along the line V-V of FIG. 2.
FIG. 6 illustrates the upper portion of FIG. 2, but with the upper section of the housing of the set and the upper portion of the ear hook portion removed.
FIG. 7 shows the upper portion of the ear hook of FIG. 3, but without the spring.
FIG. 8 represents a portion of the ear set housing with a slight modification over FIG. 1, inasmuch as it is provided with an ear plug to better adapt the ear piece or ear set for use under ambient noise conditions.
FIG. 9 is a section taken along the line IX-IX of FIG. 7.
The ear set according to the present invention is characterized primarily in that the housing portion which houses electronic sound receiving and emitting equipment, and the connecting lever or ear hook which preferably also houses some electronic equipment are pivotally interconnected while the pivotal connection includes electrical connecting means for establishing safe reliable electric contact between the electronic equipment in said housing and the electronic equipment which may be provided in said lever.
Furthermore, said pivotal connection has associated therewith spring means which continuously urge the free end of said lever to move toward the housing.
In this way, the space between the housing and the lower end of the lever or hook adapts itself to the ear of the wearer of the ear set according to the invention while simultaneously at all times clamping itself safely to the ear of the wearer. Due to the electric connection within the pivotal arrangement it is possible to fully make use of the space in the lever for locating the electric equipment therein because said electric connections in said pivotal arrangement assures a fool-proof safe electric connection between the electronic equipment in said housing and in said lever.
Referring now to the drawing in detail, FIG. 1 illustrates the new ear set 1 according to the invention as worn over one ear and also shows the mouth tube 2, and ear set cord 3 with plug 4, which may be a twoprong plug or a one-prong plug as used, e.g., in aviation. The mouth tube 2 leads into the interior of the ear set 1 and has its free end provided with a microphone 5. As will be more clearly seen from FIGS. 2 and 3, the ear set according to the invention comprises a first housing section 6 shown in FIG. 2 and a second housing section 7 shown in FIG. 3. Both housing sections 6 and 7 are made to fit together one above or adjacent to the other so as to define with each other a chamber or a plurality of chambers for receiving miniaturized electronic sound receiving and emitting components of any desired or standard type, such as are necessary, for instance, for the receiver amplifier, speaker, etc. Inasmuch as the electronic equipment does not form a part of this invention and may be of any standard or desired type, there is only by way of example mentioned that for instance the speaker may be arranged at 8 while the receiving amplifier may be arranged, e.g., at 9. The two housing sections 6 and 7 are held together by screws 10. That outer surface of the housing sections 6, 7 which, when the ear set is on the ear of the wearer, faces toward the wearer, is designated with the reference numeral 7a, and is provided with perforations 8b to release the sound coming from the speaker in the ear set.
The ear set according to the invention furthermore comprises an ear hook or lever 11 which is pivotally connected to the housing 6, 7 as will be described in detail further below. The lever 11 is likewise composed of two sections, namely the sections 11a and llb which are held together by screws 12 and together define a chamber adapted to receive and house an electronic component 13 of the respective desired type. The housing 6, 7 and lever 11 are preferably made of moldable plastic material. As will be seen, in particular from FIG. 4, the ear hook or lever 11 has in conformity with the present invention, a bend at 14, thereby dividing the lever 11 into a shorter upper part with the outer surface section 14b and a longer lower part with the outer surface section l4a. The surface section 14a is offset from the surface section 14b to form an angle, preferably within the range of from 4 to 6, but this angle is not limited to this range. The main requirement in this connection is that when the ear set according to the invention is in its position of use, i.e., hooked over an ear as shown in FIG. I, the surface section 14a will at least approximately follow the contour of and snugly engage the adjacent mastoid bone, while the plane of the surface section 1412 is preferably located in approximately the same plane as that surface of the ear set housing which faces and is closest to the ear of the wearer of the ear set when the latter is in its position of use. The bend at 14 is of great importance in connection with the present invention, inasmuch as due to this bend, at least the lower portion of the longer lower part of lever 11 will closely and snugly engage the mastoid bone of the wearer of the ear set when the latter is in its position of use. As a result thereof, the outer housing surface 7a is urged closely against the ear of the wearer and will be given the desired close fit on the ear.
A high satisfactory angle by which the surface section 14a is offset from 14b would be, for instance, an angle of from 3 to 10, but it is to be understood that this angle could also be somewhat less or more. The only important point in this connection is that the lever portion downwardly from the line where the bend occurs must at least approximately follow the contour of the mastoid bond or head portion behind the respective ear so that while resting thereagainst, the lever surface section 140 will urge the housing close to the ear of the wearer. Since the mastoid bones on opposite sides of the head slant in opposite directions, it will be evident that the ear set according to the invention made to be worn over the left car must not be worn over the right ear and vice versa.
Referring now to the double purpose joint pivotally connecting lever 11 to housing 6, 7, this joint is best shown in FIGS. 2, 3 and to 7. As will be seen from HO. 5, each of the two housing sections 6 and 7 interconnected by screws (FIG. 2) respectively has an eye 6b with a bore 6c, and an eye 7b with a bore 7c. The bores 60 and 7c are in axial alignment with each other when the housing sections 6 and 7 are connected to each other. Each of the eyes 6b, 712 has a circular depression 14 and 15 respectively (FIG. 5) coaxial with the bores 60 and 70 respectively. In these depressions there are located and fit contact discs or rings 16 and 17 respectively, each having a central bore 16a and 17a respectively of a greater diameter than the respective pertaining bores 6c and 70 so that the metallic pin 18 passed through bores 6c and 7c will not contact and thereby short circuit the contact disc 16 and 17, each of which has a tongue 16b and 17b respectively. The tongues 16b and 17b are electrically connected to respective electronic components in the housing 6, 7. Similarly, each of the ear hook or lever sections 11a and 11b has an eye 19 and 20 respectively with a circular depression 19a and 20a on the outside thereof. Also substantially centrally through each of these depressions extends a bore 21, 22 respectively of substantially the same diameter as that of the bores 16a and 17a and in alignment therewith when the lever 11 is in proper assembled position shown in FIGS. 2 and 3. The bores 21 and 22 are substantially coaxial with said depressions 19a and 20a respectively. Fitted into the depressions 19a and 20a are contact discs or rings 23 and 24 respectively, each having a central bore 23a and 24a therethrough of a greater diameter than that of bores 21, 22 so that when pin 18 is passed through bores 21 and 22 no short circuiting of contact discs 23 and 24 can be caused by pin 18. Each of the contact discs 23 and 24 has a tongue 23b and 24b respectively for electric connection with the poles, e.g.. of an electronic component in the ear hook or lever 11.
As will be seen from FIGS. 6 and 7, the tongues 23b and 24b pass from the outside of the lever eye to the inside of the lever. As will furthermore be seen from FIG. 5, the contact discs l6, 17 are respectively in electric contact with the respective adjacent contact discs 23, 24 and are held in this contact by pin 18 inserted from the outside of housing section 7 and having an axial threaded bore 18a engaged by a correspondingly threaded pin 30 screwed into pin 18 from the outside of housing section 16. The pin system 18,30 simultaneously forms the pivot pin about which lever 11 is pivotable. As will furthermore be seen from the drawing, especially FIGS. 2, 3, 6 and 7, the eyes of housing sections 6 and 7 have complementary recesses 25 and 26 in which an end portion of a pressure srping 27 is located whereas the other end portion of spring 27 is located in complementary recesses 28, 29 provided in the eyes 19, 20 of the lever sections lla and 1 lb. lnasmuch as spring 27 is inserted into recesses 25, 26 and 28, 29 under preload, it will be appreciated that the free end of lever 11 is continuously urged to pivot about pin system 18, 30 toward housing 6,7. Thus, the pivotal connection 16, 17, 23, 24, 18, 30, and 27 has a double purpose function namely to assure proper electric contact between the contact discs in the housing sections 6, 7 on one hand and the contact discs in the lever sections 11a, 11b on the other hand, and furthermore to continuously urge the lower portion of lever 11 toward housing 6, 7 to thereby hold the ear set in tight condition on the ear.
FIGS. 7 and 8 show a slight modification of the ear set of FIGS. 1-7. If the ear set according to the invention is to be used in areas with considerable ambient noise, the perforations 8b are replaced by an ear plug 31, e.g., of plastic or rubber, which has a central conduit therethrough leading from the inside of the housing section 7 to the outside of the ear plug.
As will be seen from the foregoing description, the ear set according to the present invention is characterized primarily by its snug and firm fit over the ear of the wearer, which makes possible the employment of a rather short mouth tube thereby increasing fidelity and gain. Furthermore, the pivotal connection of the ear hook or car lever simultaneously serves three purposes, namely, for pivotal connection of the ear lever to the housing of the set and to always assure reliable electric connection of electronic equipment in said lever with the electronic equipment in the housing. This last mentioned arrangement permits fully to use the space in said lever for mounting therein electronic equipment which in turn makes it possible to reduce the size of the housing 6, 7 and thereby the overall size of the ear set according to the invention. The third and very important purpose of the ear lever connection consists, of course, as mentioned previously in assuring the snug fit of the ear set on the ear and head of the wearer.
When placing the ear set over the ear, it is most convenient to pivot the free end of the lever 11 away from the lever until its stepped portion 11d (FIG. 3) abuts the oppositely located stepped portion 1d of housing 1. When the set has been put on the ear, the set is released and the free end of lever 11 is, by spring 27, moved back toward housing 1 where it stops at a slight distance away from the housing 1, in conformity with the space taken up by the ear portion between the housing and the lever of the set. When the ear set is taken off the ear and the ear lever is released, the lever will stop at a slight distance from the housing, namely when step lle (FIG. 6) abuts step 12 of housing 1. However, the steps le and 112 are not absolutely necessary, but if they are lacking, lever 11 might impact upon the housing when released and could possibly damage the highly sensitive electric equipment in the housing.
It may also be mentioned that the mouth tube 2 leads into housing 1 (see FIG. 1) where the housing is closest to the mouth in the specific exemplary showing in the drawing near the lowermost area of housing 1 whereby the length of the mouth tube is reduced to a minimum which, in turn, yields better fidelity and gain.
It is, of course, to be understood that the present invention is, by no means, limited to the specific showing in the drawing, but also comprises any modifications within the scope of the appended claims. As plastic material for the housing, any suitable and standard moldable plastic material may be employed, preferably such which is electrically insulating, as, for instance the material known under the trade name Cycolac made and sold by a Division of the Borg-Warner Corporation.
