Definitions

  • the invention relates to a hearing aid with an electrodynamic sound transducer as e.g. is known from patent application P 43 29 892.2.
  • the invention based on this application was based on the task of developing a sound transducer of the type mentioned in the prior art with the smallest possible dimensions, which then meets the apparently contradicting requirements for high sensitivity with high impedance and large transmission bandwidth.
  • the object of the present invention is to design a hearing aid of the type mentioned at the outset, which is simple to manufacture, can be individually adapted to the user and has good reproduction quality.
  • a hearing aid with an electrodynamic sound transducer in which the hearing aid has a housing with a movably mounted ear tube, through the interior of which sound waves generated by the membrane of the electrodynamic sound transducer can be transmitted.
  • Advantageous developments of the invention are described in the subclaims.
  • the sound transducer itself is preferably constructed according to the construction principle described in P 43 29 892.2. In principle, however, other dynamic converters can also be used.
  • a hearing aid which can be mass-produced and still has an ear tube that can be individually adapted to the ear canal, that is the area of the hearing aid that can be inserted into the ear canal of the human ear.
  • excellent sound reproduction is possible due to the excellent sound transducer quality.
  • the difference in quality between a hearing aid according to the invention and the previous hearing aids is particularly clear on the basis of the transmission bandwidth, because with previous hearing aids a reasonable hearing gain is achieved only in a narrow-band range, while with the hearing aid according to the invention a good reproduction quality over the largest Part of the audible frequency band is reached. This significantly increases intelligibility and the occurrence of strong levels is only avoided in a small frequency range. In addition, the reproduction is more realistic for the user.
  • the production of the otoplastic can be completely dispensed with in the hearing aid according to the invention, since the ear tube can be individually adjusted according to the shape of the auditory canal due to its mobility.
  • the solution according to the invention allows the user to adapt and facilitate the hearing aid himself to his ear.
  • the invention allows the hearing aid to be used even by users for whom it has not previously been possible to produce an otoplastic.
  • the ear tube is inclined to a main axis of the hearing aid housing or the sound transducer and is mounted so as to be rotatable about the main axis. If the rotatable bearing is self-locking, the ear tube is automatically adequately fixed.
  • the part of the ear tube that can be inserted into the human ear canal itself has a hollow cylindrical shape, the outside of which has at least one annular circumferential projection for holding a preferably sound-absorbing filling medium, e.g. B. in the form of a foam.
  • the interior of the hollow cylindrical part forms the sound passage space of the ear tube while between the outside of the ear tube and the inner wall of the ear the sound-absorbing medium can be arranged, which prevents sound access through the gap between the outside of the ear tube and the inner wall of the ear.
  • the filling medium also improves the fit of the hearing aid in the human ear. So while a rough adjustment to the shape of the human ear canal can be made by the movable ear tube, the filling medium in the ear canal ensures fine adjustment and at the same time prevents sound passage through the gap between the ear tube and the auditory canal.
  • the latter For the rotatable mounting of the ear tube, the latter has a region partially enclosing the sound transducer, which is provided on the inside with an annular circumferential projection, which in turn is mounted in an annular circumferential groove of the hearing aid housing.
  • a holding connection of the eartub body to the hearing aid housing is thus simultaneously established and rotation of the eartube about the axis of rotation, which coincides with the main axis of the sound transducer, is possible.
  • the connection allows a self-locking stepless rotation of the ear tube, so that it can take any desired setting angle.
  • the ear tube it is also possible to mount the ear tube so that it can move in multiple axes, which is possible, for example, by means of a ball-and-socket joint or spherical shell bearing.
  • the multi-axis mounting increases the degree of freedom of mobility of the ear tube, which results in even better adaptability to the human ear canal.
  • the microphone of the hearing aid is housed within a housing part, which is located relatively far from the sound transducer. This makes it possible to provide one or more partitions between the sound transducer and the microphone, so that a complete decoupling of the sound outlet of the sound transducer and the sound entry of the microphone is achieved, thereby eliminating undesirable feedback effects from the outset. This makes it possible to also use medium-quality components for sound signal processing use and recording and at the same time a sufficiently large amplification of the sound signals can be set.
  • the hearing aid has a controller which is freely accessible to the user and which permits the gain desired by the user by changing the state of an amplifier circuit.
  • the housing consists essentially of two connectable parts, the housing part lying away from the ear being able to be provided with a decorative cap which is connected to the housing by a snap connection.
  • a decorative cap can be provided with a fashionable design, so that the hearing aid not only fulfills its functional purpose for alleviating hearing damage, but also serves as a fashion accessory, so that the inhibition threshold for wearing a hearing aid drops further.
  • the part of the ear tube lying in the auditory canal in the sound transmission space is at least partially, if not completely, covered by a sound-permeable medium such as, for. B. foam is filled, which allows the sound uninsulated, but at the same time prevents the ingress of dirt, especially cerumen.
  • cerumen is a relatively aggressive medium, which can damage sensitive electrical and electromechanical parts of the hearing aid, in particular the sound transducer, by touching the sound-permeable medium as a protective shield against penetrating objects is very advantageous. Should the sound-permeable medium itself become contaminated, it can be replaced in a simple manner by pulling it out of the interior of the ear tube and replacing it with a new medium.
  • Relatively coarse foam has proven to be expedient as an embodiment of the medium.
  • the volume control 8 is a setting wheel rotatably mounted in the housing 5 of the hearing aid 1, by means of which the volume of the sound reproduction of the hearing aid 1 can be adjusted.
  • the volume control is designed as a flap 20 which can be opened via a joint 21 in order to accommodate a battery 22a in a battery compartment located under the flap.
  • FIG. 2 shows a section through the hearing aid shown in FIG. 1 along the line AA.
  • the housing 5 of the hearing aid 1 essentially consists of two parts 5a and 5b, which by means of a in Fig. 3 screw connection shown are held together by screws 19. While one part 5a, which forms the part of the housing lying away from the ear, accommodates the volume control 8 and the battery, the other part 5b, which faces the human ear, houses the sound transducer 10, the construction of which is described in detail with reference on the drawings 6 and 7 will be explained later.
  • part 5b has an ear tube body 7 or ear tube 2 with another part, which has a sound channel 3 and is formed as a protruding projection 11, which can be inserted into the ear canal of a human ear.
  • the protruding extension 11 of the ear tube 7 is hollow-cylindrical in order to form the sound channel 3 on the inside.
  • the extension 11 of the ear tube 7 has circumferential projections 12 or rings, by means of which a filling medium 4 shown in FIG. 4b can be held.
  • the filling medium 4 is a foam and is used to soundproof the space between the ear tube extension 11 and the inner wall of the ear so that the transducer works as a pressure chamber.
  • the hollow cylindrical extension 11 receives a sound-permeable protective foam 23, which prevents the penetration of objects such.
  • the ear tube 7 is rotatably mounted about a main axis HA of the hearing aid 1, in which a part 13 of the ear tube 7 protruding into the hearing aid has an annular projection 14 on the inside, which cooperates with an annular circumferential groove 13 of a corresponding counterpart of the housing part 5b.
  • a self-locking rotation of the ear tube about the main axis HA is possible and, in addition, sufficient fastening of the ear tube to the housing part 5b is produced.
  • the extensive construction of the ear tube around the area of the sound transducer 10 ensures optimal sound transmission from the sound transducer 10 via the sound channel 3 enables.
  • the central axis OA of the extension 11 of the ear tube is set at approximately 45 ° to the main axis HA.
  • Fig. 3 shows the hearing aid shown in Fig. 2 in cross section along the line B-B as in Fig. 1. It can be seen here that the microphone 16 is relatively, i.e.. about 0.8 to 1.5 cm away from the sound transducer 10 and is arranged directly below the sound inlet opening 9 of the hearing aid 1. A sound-permeable medium 15 is provided between the sound entry opening 9 and the sound entry opening of the microphone 16, which prevents the penetration of dirt and other substances, but allows an undamped sound passage.
  • the microphone 16 is delimited by a circuit board 17 on which the components for the signals delivered by the microphone for sound signal processing and amplification are arranged.
  • a sealing ring 18b is provided from the center for sound sealing between the sound transducer area and the microphone area in order to improve the sound decoupling between the microphone 16 and the sound transducer 10.
  • FIG. 5a shows the hearing aid according to the invention in a side view, in which the shape of the circumferential projections 12 of the ear tube 11 can be seen particularly well.
  • a side view of the volume control 8 is shown again in FIG. 4a.
  • the elevations 8a located on the volume control serve to facilitate the rotation of the volume control and to form a point of attack for the user when adjusting the volume.
  • the moveable mounting of the ear tube enables a user to bring the ear tube extension into such a position, that the ear tube fits into the ear canal of a human ear.
  • the housing of the hearing aid can be brought into a position adapted to the ear cup.
  • the medium 4 surrounding the ear tube extension is used for the fine adjustment, which acoustically seals the space between the outer surface of the ear tube extension and the wall of the auditory canal and has a strong sound-absorbing property that the sound cannot pass through the gap between the ear tube and the wall of the auditory canal.
  • the hearing aid in the event that the hearing aid is switched off by the user or the volume gain is set to zero, the hearing aid also serves as hearing protection with which a high level of sound insulation can be achieved over large parts of the audible frequency range.
  • a converter 10 for use in the hearing aid is described below.
  • a converter 10 as was previously known from the published prior art, follows from the construction principle known in FIG. 8. Only the lower transducer part 41 is shown there, which is used to support a membrane 20.
  • the converter 10 is rotationally symmetrical to a dash-dotted line Shaped axis 42 and includes a cup 43, which merges into a radial flange 44 because of the design of the known membrane 50 to be explained in more detail and finally ends there in a ring insert 45.
  • a ring magnet 46 In the interior of the bowl 43 there is a ring magnet 46, the inner opening of which forms a sound passage 49 which also passes through the housing shell surrounding it.
  • the outer circumference of the ring magnet 46 includes with the cup 43 an annular gap 66, into which a wire coil 60 is immersed when the membrane 50 is installed.
  • the associated membrane 50 can essentially be divided into two differently profiled parts 51, 52.
  • the actually sound-effective component of the membrane 50 lies in the middle of the membrane and consists of a central part 51 with a cap-like curvature 54.
  • This central part 51 of the membrane 50 is usually referred to as a "calotte".
  • the largest possible diameter 55 of the central part 51 is desired.
  • a certain rigidity of the central part 51 is advantageous for good acoustic reproduction or for acoustic reception.
  • the diameter dimension 55 is limited by the arrangement of the second membrane ring part 52 for the following reasons.
  • the central part 51 in the known membrane 50 is surrounded by a radially outwardly extending ring part 52 of the membrane 50.
  • the ring part 52 in turn has an arcuate profile 56, the convex side of which faces in the same direction as the above-described cap curvature 54 of the central part 51.
  • This ring part 52 is usually referred to as a "bead” and has the function of providing an elastic suspension of the central part 51 in the converter housing 51.
  • the outer peripheral edge 57 of the known membrane 50 is provided with a stepped fastening edge 58 which is supported on the aforementioned ring shoulder 55 of the converter housing 51.
  • the central part 51 and the ring part 52 there is a narrow ring zone which serves as a coil seat 53 for a coil 60.
  • the coil 60 is fixedly connected to the coil seat 53 by its one cylindrical front end. Consequently, in the application as a sound receiver, axial movements of the central part are transmitted to the coil 60, and vice versa, in the application as a sound transmitter, as in the hearing aid 1, axial movements carried out by the coil are transferred to the central part 51 carrying it.
  • the ring part 52 In order to ensure the desired good mobility of the central part 51 when interacting with the sound, it is desirable to also give the ring part 52 the largest possible dimension. Taking into account the aforementioned fastening edge 58 which surrounds the ring zone, the ring width 59 indicated in FIG. 8 is added to the diameter 55 of the central part 51. This leads to considerable external dimensions 48 of the converter housing 41.
  • the sound transducer 10 ′′ in FIGS. 6 and 7 has a completely new construction principle compared to the sound transducer shown in FIG. 8.
  • the same reference numerals as in the converter 10 according to FIG. 8 are also used in FIG. 7 to designate attractive components, but to distinguish them, they are identified by a double line (''). In this case, unless stated otherwise, the preceding description of the transducer applies.
  • the two diaphragm portions 51 ′′, 52 ′′ are not located radially next to one another but in the axial direction of the axis 42 ′′ of FIGS. 6 and 7, in an axial staggering with respect to one another.
  • the coil seat 53 ′′ is also the component that determines the outer boundary of the central part 51 ′′ here, but this coil seat 53 also determines the maximum outer diameter 55 ′′ of the entire membrane.
  • the ring part 52 there adjoins the coil seat 53 there radially outwards, in the converter 10 ′′ according to FIG. 6 the ring part 52 ′′ extends radially inwards.
  • the ring part 52 ′′ lies with its arch profile 56 ′′ completely in the curvature area 54 ′′ of the central part 51 ′′.
  • the fastening edge 58 ′′ of the membrane which is also located here at the free edge of the ring part 52 ′′, no longer determines the outermost outline of the membrane, as in FIG.
  • the ring width 59 ′′ occurring in the membrane 50 ′′ according to the invention is no longer additive to the central part diameter 55 ′′, as in the known transducer 10 from FIG. 8.
  • This ring width 59 ′′ has no influence on that from FIG. 7 external dimensions 58 '' of the converter housing lower part 41 ''.
  • the ring magnet 46 ′′ shown in FIG. 7 carries a ring shoulder 61 ′′, for example a ring embedded therein, which serves as a support for the membrane fastening edge 58 ′′ for fastening purposes.
  • the ring extension 61 ′′ defines the axial sound passage 49 ′′ in the converter housing 41 ′′. 7 also shows the upper converter part 62 ′′ belonging to the lower converter part 41 ′′.
  • the housing shell 43 ′′ already described above for the lower converter part 41 ′′ runs out cylindrically and, while maintaining a small external dimension 48 ′′, settles into a cylindrical extension of the upper housing part 62 '' away.
  • the space-saving construction principle of the transducer makes it possible to build up the compact hearing aid shown in FIGS. 1 to 4.
  • the compact design of the hearing aid results in considerable weight and space savings, and the sound transducer also allows sound reproduction over a large frequency range and not just a very narrow band-limited range for hearing aids that have so far been manufactured using individually otoplastic preparatory work.
  • the arrangement of the microphone described relatively far from the sound transducer is not mandatory, but that the microphone can also be arranged near the main axis of the hearing aid. However, sufficient decoupling must then be provided between the sound input of the microphone and the sound output of the sound transducer, in which further sound seals such as the sealing ring 18b are specified.
  • the hearing aid according to the invention can be deliberately designed to be conspicuous on the outside in order to also serve as a fashion accessory in addition to its medical technical purpose. Therefore, the cover plate 70 is not skin-colored as in previous hearing aids, but can be equipped with different designs, colors and motifs so that the hearing aid can serve as ear jewelry and a hearing amplifier at the same time. As a result, the inhibition threshold before the use of such a device is lowered for the user and / or the attractiveness of the hearing aid application is also increased for users who have already been found to have hearing damage. However, for reasons of cost, it has so far been refrained from producing expensive otoplastic hearing aids.
