4 Claims. 1
This invention relates to acoustic devices and it has among its objects a simple, universally-adjustable and foolproof acoustic insert for acoustically coupling a sound outlet opening of a sound transmitting device, such as a hearing-aid earphone, to the ear canal of a person, and prevent direct transmission of sound thereto.
The foregoing and other objects of the invention will be best understood from the following description of exemplifications thereof, reference being had to the accompanying drawings where- Fig. 1 shows a vertical cross-sectional view of an acoustic device exemplifying one form of the invention;
Fig. 2 is a horizontal cross-sectional view through an ear with the device of Fig. 1 held therein;
Figs, 3 and 4 are views similar to Fig. 1 of other forms of acoustic devices exemplifying the invention; and
b Fig. 5 is a vertical sectional view of an ear-protecting acoustic device equipped with an ear insert of the invention.
Various forms of ear inserts for acoustically coupling a sound outlet opening of a sound transmitting device to the ear canal of a person have been suggested in the past. In hearing aid earphones in connection with which ear inserts are most commonly used, most of the ear inserts are usually made of hard synthetic resin material and molded from a plaster cast so as to fit the outer ear cavity and establish a good acoustic seal between the sound outlet of the receiver and the ear canal, the ear insert serving also to support the receiver on the ear of the user.
Ear inserts are also used in connection with ear protector devices which are placed against the ear for controlling the transmission of the sound in such manner as to prevent excessive sounds, such as caused by a bomb explosion or gun concussion, from injuring the ear organs, while permitting normal sound, such as speech, to be transmitted to the hearing center of the user.
Various attempts have been made in the past to provide a universally-adjustable ear insert for such sound transmittin devices. However, individual ears differ greatly in size and shape and have outer ear cavities of greatly varying configurations. As a result, great difliculties have been encountered with prior adjustable ear inserts because in most cases, the insert either exerted too great pressure or failed to provide a good acoustic seal between its sound transmitting passage and the ear canal.
. be either The ear insert arrangements of the present invention, the various novel features of which will be described hereinafter in connection with specific exemplifications thereof, overcome the difficulties encountered with prior art adjustable ear inserts, thereby making it possible to fit ears of a great variety of configurations and sizes with only a few sizes of ear inserts of one standard construction.
Referring to Figs. 1 and 2, a sound transmitting device I 0 is provided with an ear insert II, in the form of a conduit or channel member shaped for insertion into the concha or the outer cavity of an ear. The sound transmitting device I0 may a hearing aid earphone, such as de-- scribed in Carlisle et a1. Patent No. 2,344,023, or an ear protector device, such as shown in Fig. 5. The sound transmitting device In is housed in a casing, one side of which has a cap wall [2 with a projecting sound outlet knob l3 provided with a sound outlet passage opening M from which sound is transmitted to the ear canal of the user.
The ear insert conduit or channel member H has formed therein a sound passage 20 extending axially therethrough. The rear end of the channel member H serves as a coupling wall section 2| and has formed therein a cavity 22 in which is held the female part of a snap fastener clasp 23 formed of spring metal and having a plurality of spring arms 24 bent to slide on and engage the tapered side surfaces of the sound outlet knob 13 and to retain it tightly in the locked position shown so that the facing wall surfaces of the coupling section 2l' and the cap wall l2 form a tight acoustic seal around the cavity space which couples the outlet opening I 4 to the sound passage 20 of the insert H.
The body of the channel member (I may be made of relatively soft rubber-like material, such as a soft grade of Neoprene. As indicated in Fig. l, the sheet metal clasp 23 may have, in addition to the spring arms 24, extending from the central ring-shaped anchoring element thereof, a plurality of flat anchoring arms 25 which are embedded in the molded body of the coupling wall section 2! so as to be firmly anchored therein and give it the rigidity required in order that it may serve as a good coupling connection between the channel member H and the outlet wall of the sound transmitting device 10. The clasp arrangement shown permits ready removal of the ear insert II from the sound transmitting device ID as well as attachment thereto.
The major part of the ear insert channel momball-shaped ball-like wall sections 3|, 32, 33,.
which are interconnected to each other and to the coupling wall section 2| by thin and short neck-like wall sections 35, 36, 31. The ball-like wall sections 3|, 32, 33 are each made with sufliciently thick walls as to give them great stiffness and prevent substantial distortion of the cross section of the sound-passage portions extending therethrough under the action of external bending forces to which they are subjected when the channel member II is inserted into the curved space of the outer ear cavity. The short necklike junction elements 35, 33, 31 are formed out of thin, flexible wall portions and they are so designed in relation to the thick ball-like wall sections 3|, 32, 33 that when the forwardly protruding channel member H is bent, for instance, in the manner indicated in Fig. 2, on being inserted into the curved space of the outer ear cavity, only the short neck-like junction portions 35, 36, 31 will be flexed, the thick ball members 3!, 32', 33 being provided with walls of sufficient thickness and stiffness to keep open the sound passage portions through the short junction necks 35, 35, 31.
In other words, the wall elements of the rela tively thick and longer ball-like members 35, 32, 33 are so proportioned in relation to the thickness and the short length of the junction necks 35, 36, 31 of the channel member that when the ball members 3!, 32, 33 are bent at various angles relatively to each other along their junction portions 35, 36, 31, respectively, the sound passage 20 through the junction portions 35, 33, 33 remains open and the entire sound passage 23 of the channel member remains fully effective for transmitting sound from the sound transmitting device toward the ear canal of the user, the mouth of which is engaged by the exterior periphery of the outermost bead member 33, in the manner indicated in Fig. 2.
In an acoustic ear insert channel member of the invention of the type described above, each of the ball-like members 3|, 32, 33 of its forward part extending through the ear cavity, has relatively great wall thickness-and stiffness sufficient to prevent any substantial deformation of the cross section of the sound passage extending therethrough when the channel member is bent incident to its insertion into its operative coupling position within the ear cavity for completing an acoustically sealed sound passage between the outlet opening of the sound transmit-- ting device and the mouth of the ear canal.
The channel member II is given the required flexibility so that it may be readily flexed and assume the bent shape conforming to any peculiar curved shape of the outer ear cavity into which it is inserted, by making each short neck-like wall section 35, 36, 31 suificiently thin and sufficiently short so as to cause it to readily flex and take up substantially the entire deformation to which the channel member is subjected, while assuring that the stiffness of the adjoining thick ball-like wall sections keeps the sound passage of each short cross section open in its flexed deformed condition.
The neck portions 35, 3B, 31, although highly flexible, are also made sufilciently short so that the entire channel member, the principal elements of which are formed by the stiff ball-like elements 3!, 32, 33, has the characteristics of a relatively firm post, which, when inserted into the ear cavity, will push the front elements of the channel member toward the mouth of the car 4 canal and force it into engagement therewith, notwithstanding the great flexibility of the junction neck portions 35, 36, 31.
As shown in Figs. 1 and 2, the forward flexible part of the ear insert channel wall member is provided with a plurality of thin flexible skirtlike protrusions 4|, 42, 43 projecting in outward and rearward direction so that upon insertion of the ear insert channel member into the ear cavity, the outer edge region of the individual protrusions 4|, 42, 43 will engage and become wedged against the surrounding surface portions of the outer ear cavity for automatically establishing therewith an acoustic seal which prevents propagation of sound through the space of the ear cavity surrounding the exterior of the channel member.
The ear insert of the type shown in Figs. 1 and 2 will readily fit and establish with its exterior elements good acoustic seals with ear cavities of different shapes and configurations and of different sizes. For instance, if an ear insert of the type shown in Figs. 1 and 2 has to fit into an ear cavity of smaller length, the outer bead-like element 33 may be cut off at or below its junction neck element 31. For ears having particularly short ear cavities, both bead-like elements 32 and 33 may be cut off. In general, two or three standard sizes of flexible ear tips of the type de-v scribed in connection with Figs. 1 and 2 will be suflicient for providing adjustable ear inserts for ears of substantially every size, shape and configuration.
As shown in Fig. 3, a channel member :5 similar to that described in connection with Figs.
1 and 2, may be provided with a coupling wall section 2 arranged so that the axial direction of the sound passage 2U-| is inclined to the axis of the sound passage in the outlet knob l3 of the sound transmitting device I0.
As shown in Fig. 4, the sound transmitting device |0 may have a cap wall member |2-| de signed to form the rear part of a channel wall member ll2 of the type described above in connection with Figs. 1 to 3. The cap wall member |2--| is embodied in the' molded rear part 2 |2 of the channel member and serves for coupling the channel member to the sound transmitting device, being thus a part thereof. The coupling wall section 2|-2 may be molded so as to have formed thereon horn-like extensions 35 provided with grooves 46 arranged to engage and be retained within the fossa and below the underlying portion of the helix so as to be retained and held firmly therein when inserted in the ear, in the manner analogous to that described in the Aber Patent No. 1,753,817.
Fig. 5 illustrates an ear insert of the type described in connection with Figs. 1 to 3 forming part of an ear protector which is designed to con trol the transmission of sound to the ear so as to prevent bomb explosions, gun concussions and similar abnormal sound phenomena from injuring the ear, while permitting speech and similar sound to be efficiently transmitted to the hearing organs.
The ear protector is shown formed of a plurality of circular sheet elements 5|, 52, 53, held in position within the casing elements It, l2 by a series of spacer washers 56, 51, 58, 59, so as to provide thin air spaces between the individual sheet elements. The several sheet elements are provided with small sound passage openings 5 52|, 53| which are offset relatively to each other so that when one of the sheet elements, for
instance, element 52 is deflected in one direction or the other, its sound passage opening 52l will be substantially closed through engagement of the surrounding sheet surface with the facing sheet surface of either sheet element or sheet element 53.
One of the sheet elements, for instance, the central sheet element 5| may be made of limp and light material, such as Vinylite, which has negligible stifiness and resiliency so that it is not set into vibrations by normal speech, but is actuated to close its opening 5ll by a large air pressure Wave or the vacuum reaction following it, which take place when a bomb explosion or gun concussion take place.
The two outer sheet elements 5|, 53 may be substantially rigid. Normal speech will be propagated through the sound passage opening l0-l of the casing l0 and therefrom through the openings SI-l, 52--l, 53-l of the several sheet elements and the air spaces therebetween toward the sound outlet passage I4, and therefrom through the sound passage 20 in the channel member II to the ear canal.
Various other modifications of the invention will suggest themselves to those skilled in the art. It is accordingly desired that in construing the breadth of the appended claims they shall not be limited to the specific details shown and described in connection with the exempliflcations of the invention.
