[0002] Typical hearing aids for supplying hearing-impaired persons are generally referred to as hearing devices. However, in a broad sense, this term especially also denotes devices that are configured to support persons with normal hearing. Such hearing devices are also referred to as "Personal Sound Amplification Products" or "Personal Sound Amplification Devices" (abbreviation: "PSAD"). Personal Sound Amplification Products or Personal Sound Amplification Devices are not provided to compensate for hearing loss, but are specifically used to support and improve the hearing of normal persons in specific hearing situations, for example, to support hunters during hunting, or to support animal observation in order to better perceive the sounds of animals and other noises generated by animals, to support sports journalists in order to improve speech and / or speech understanding in complex background noise, to support musicians in order to reduce the hearing load, etc.
[0003] Irrespective of the intended use, as main components, hearing devices generally especially have an input transducer, a signal or data processing device that usually includes an amplifier, and an output transducer. Here, the input transducer is usually formed by an electroacoustic transducer, i.e., for example, by a microphone and / or by an electromagnetic receiver, such as an induction coil. As the output transducer, an electroacoustic transducer, such as a miniature loudspeaker (also referred to as a "receiver"), or an electromechanical transducer, such as a bone conduction receiver, is usually used, and the signal processing device is usually implemented by an electronic circuit implemented on a circuit board. Summary of the Invention

Preferred expansions are included in the following description. The advantages and preferred design solutions mentioned with respect to the hearing device can equally be transferred to the hearing device set and / or the hearing device module, and vice versa.
[0006] A hearing device according to the invention, generally constructed in accordance with the type of hearing device described at the beginning, is preferably part of a binaural hearing device kit according to the invention and has a hearing device module according to the invention.

[0009] In addition, the transmitting and receiving unit has a radio conductor loop, and the radio conductor loop is integrated in the hearing device module. Here, preferably the hearing device is designed such that f 充电 is less than f 无线电 . Here, then the ratio f 无线电 / f 充电 is preferably in the range from 10 to 100, and in particular in the range from 20 to 50.
[0010] Independently thereof, in a hearing device according to the invention, a very compact structure is generally achieved, and at least a partially modular structure is achieved by means of the hearing device module. Here, the corresponding hearing device module is generally prefabricated and installed during the final installation of the hearing device. Here, in most implementation variants, the hearing device module has a housing or a carrier unit for the remaining components, parts or structural components of the hearing device module. Such a housing or such a carrier unit then generally has a plurality of fixing elements for mechanically fixing the hearing device module in the hearing device, and generally has a plurality of connection elements, such as connection contacts, for electrically connecting the hearing device module to other components in the hearing device.
[0011] According to an implementation variant, here, the accumulator forms such a housing or such a carrier unit. According to an alternative design, the hearing device module has, for example, a base body configured as a hollow body as the housing or carrier unit. Then, the accumulator of the hearing device is generally arranged and / or fixed in or on such a base body. In addition, preferably, a part of the charging circuit is installed in and / or fixed on the base body.
[0012] Now, if the hearing device module has the aforementioned base body, the base body is preferably made of a ferromagnetic (or ferrimagnetic) material, in particular a soft ferromagnetic material, or has a structure or part made of such a material. Here, the base body is made of ferrite, for example. The magnetic permeability μ of the aforementioned corresponding base body 基体 is preferably in the range between 5 and 300, and more preferably in the range between 5 and 100.
[0013] Independently thereof, such a base body generally extends along a central longitudinal axis and is designed, for example, to be cylindrical, that is, for example, designed as a cylindrical hollow body.
[0014] According to an implementation variant, a radio conductor loop is further arranged such that the radio conductor loop extends along a circumferential direction around the central longitudinal axis and around the base body and / or the accumulator. In addition, according to the implementation variant, the radio conductor loop is designed as a coil having a plurality of turns, that is, for example, designed as a cylindrical coil (Zylinderspule).
[0015] In addition, the following design is advantageous, in which the charging conductor loop is arranged such that the charging conductor loop extends along the circumferential direction, that is, in particular, the aforementioned circumferential direction around the central longitudinal axis and around the base body and / or the accumulator. In addition, according to the application, the charging conductor loop is designed as a coil having a plurality of turns, that is, for example, designed as a cylindrical coil.
[0016] In an advantageous expansion variant, on the one hand, the radio conductor loop extends along a circumferential direction around a central longitudinal axis and around the base body and / or the accumulator, and on the other hand, the charging conductor loop is configured such that the charging conductor loop extends along a circumferential direction around a central longitudinal axis and around the base body and / or the accumulator.
[0017] Furthermore, the first longitudinal section of the hearing device module and the second longitudinal section of the hearing device module generally extend along the central longitudinal axis. Here, the second longitudinal section is usually directly adjacent to the first longitudinal section along the direction of the central longitudinal axis. Here, it is considered advantageous that the charging conductor loop is arranged in the first longitudinal section and the radio conductor loop is arranged in the second longitudinal section. Here, then preferably when viewed along the direction of the central longitudinal axis, the charging conductor loop and the radio conductor loop are arranged side by side. Furthermore, here, it is preferred that the charging conductor loop and the radio conductor loop are spatially separated from each other, and then accordingly when viewed along the direction of the central longitudinal axis, a distance is provided and maintained between the charging conductor loop and the radio conductor loop.
[0018] Furthermore, it is suitable that the charging conductor loop abuts against the accumulator or the aforementioned base body. Here, then the charging conductor loop is, for example, directly or in close proximity applied, for example pressed or wound, against the accumulator or the base body. Here, according to an implementation variant, the charging conductor loop is adhered to the accumulator or the base body.
[0019] According to an alternative implementation variant, the charging conductor loop abuts against the accumulator or the aforementioned base body with additional elements arranged in between. The corresponding additional elements are then, for example, formed by a coating or a film (Folie), or have a coating or a film. Furthermore, it is preferred that such additional elements are made of a ferromagnetic material, in particular a soft ferromagnetic material, or have a structure or component made of such a material. Here, the additional elements are, for example, made of ferrite. The magnetic permeability μ of the aforementioned corresponding additional elements 基体 Preferably lies in the range between 5 and 300, and more preferably lies in the range between 5 and 100.
[0020] Furthermore, the following embodiments are typical, in which the hearing device module has a shield, in particular a shield that separates the charging conductor loop and the radio conductor loop. According to the design, the corresponding shield is, for example, a hollow cylinder. The shield generally has a conductor material or is made of a conductor material and is used for electromagnetic shielding. As the conductor material, for example, copper or a copper alloy is suitable. According to an implementation variant, the shield is formed by a film, i.e., a shielding film, where the film is, for example, made of copper or a copper alloy. According to another implementation variant, the shield for electromagnetic shielding has a conductor structure or a conductor layer, such as a metal layer or a coating.
[0021] Furthermore, the following design is advantageous, in which the charging conductor loop abuts against the shield described above, or conversely, the shield abuts against the charging conductor loop. Here, according to an embodiment, the shield is adhered to the charging conductor loop.
[0022] Furthermore, it is suitable that the hearing device module has an auxiliary body, in which generally at least a partial volume has ferromagnetic properties, in particular soft ferromagnetic properties. According to the design, the corresponding auxiliary body is, for example, a hollow cylinder. The auxiliary body generally has a ferromagnetic material, in particular a soft ferromagnetic material, or is, for example, made of a ferromagnetic material, in particular a soft ferromagnetic material. According to an implementation variant, the auxiliary body is formed by a film, i.e., an auxiliary film, where the film is, for example, made of a ferromagnetic material, in particular a soft ferromagnetic material. According to another implementation variant, the auxiliary body has an auxiliary structure or an auxiliary layer, which is, for example, made of a ferromagnetic material, in particular a soft ferromagnetic material, or at least has ferromagnetic properties, in particular soft ferromagnetic properties.
[0023] According to a design variant, the radio conductor loop abuts against the auxiliary body described above. Here, the radio conductor loop is, for example, directly applied, such as pressed or wound, onto the auxiliary body. Here, according to an implementation variant, the radio conductor loop is adhered to the auxiliary body.
[0024] If the corresponding auxiliary body is provided, then the auxiliary body is preferably positioned, applied, or wound onto the shield described above. Here, according to an implementation variant, the auxiliary body is adhered to the shield.
[0025] Furthermore, it is advantageous that the auxiliary body described above separates the charging conductor loop and the radio conductor loop.
[0026] According to another embodiment variant, the hearing device module has a module body which forms the aforementioned shielding body and / or the aforementioned auxiliary body. Such a module body then has, for example, a plurality of layers, in particular in the form of a sandwich structure, where, for example, the layer for electromagnetic shielding has a conductor structure or a conductor layer, and where one layer forms the aforementioned auxiliary layer, which is made of a ferromagnetic material, in particular a soft ferromagnetic material, or at least has ferromagnetic properties, in particular soft ferromagnetic properties.
[0027] Furthermore, in an advantageous refinement, the module body described above has a radio conductor loop and / or a charging conductor loop, where the radio conductor loop and / or the charging conductor loop are implemented, for example, as conductor traces.
[0028] Independently of this, a first radial section of the hearing device module generally extends along a radial direction transverse to the central longitudinal axis, and the first radial section in particular has a cylindrical or hollow cylindrical volume. Furthermore, it is typical for the charging conductor loop to be arranged in the first radial section. Here, the charging conductor loop is, for example, pressed directly against the battery or the substrate, or the charging conductor loop is, for example, wound directly around the battery or the substrate.
[0029] Independently of this, the maximum extension of the conductor cross-section of the charging conductor loop (diameter in the case of a circular cross-section) is generally in the range from 20 μm to 500 μm, preferably in the range from 30 μm to 300 μm, in particular in the range from 40 μm to 100 μm. Here, the conductor cross-section of the charging conductor loop generally remains substantially the same over the entire course of the charging conductor loop. Copper is preferred as the conductor material for the charging conductor loop. Other materials that are conductive and have virtually no magnetic permeability are also suitable.
[0030] In most cases of embodiment variants, an intermediate section of the hearing device module is adjacent to the aforementioned first radial section along the radial direction, and a second radial section of the hearing device module is in turn adjacent to this intermediate section. Then, the radio conductor loop is generally arranged in the second radial section.
[0031] In particular, the following design of the hearing device module is preferred, in which the charging conductor loop is arranged in the first radial section and the radio conductor loop is arranged in the second radial section. Then, when viewed along the radial direction, the charging conductor loop and the radio conductor loop are generally spaced apart from each other, where the charging conductor loop is generally positioned closer to the central longitudinal axis than the radio conductor loop.
[0032] Independently thereof, the maximum extension of the conductor cross-section of the radio conductor loop (diameter in the case of a circular cross-section) is preferably in the range of 10 μm to 100 μm, and more preferably in the range of 30 μm to 60 μm. Here, the conductor cross-section of the radio conductor loop generally remains substantially the same throughout the entire path of the radio conductor loop. Copper is also preferred as the conductor material of the radio conductor loop.
[0033] Furthermore, the following implementation variant is advantageous, in which the aforementioned auxiliary body is arranged in the middle section described above. Here, when viewed in the direction of the central longitudinal axis, the auxiliary body preferably extends only in the second longitudinal section, where, more preferably, the extension when viewed in the direction of the central longitudinal axis approximately corresponds to the extension of the radio conductor loop when viewed in the direction of the central longitudinal axis.
[0034] Independently thereof, as already explained above, it is preferred that the auxiliary film forms the auxiliary body, or the auxiliary body has an auxiliary structure or auxiliary layer with ferromagnetic properties, especially soft ferromagnetic properties. Here, it is further preferred that the auxiliary film, auxiliary structure or auxiliary layer has a thickness or thickness in the range of 20 μm to 300 μm, especially in the range of 30 μm to 200 μm or an extension in the radial direction. Thus, it is particularly a very thin film, auxiliary structure or auxiliary layer with a very small extension in the radial direction. Furthermore, it is considered appropriate that the radio conductor loop is directly applied or directly wound on the auxiliary film, auxiliary structure or auxiliary layer.
[0035] As already explained above, in some implementation variants, the aforementioned base body is provided, which is especially made of a ferromagnetic material, especially a soft ferromagnetic material. Furthermore, if the aforementioned auxiliary body is provided, then preferably the auxiliary body is used for a hearing device module, and the magnetic permeability of the hearing device module is greater than the magnetic permeability of the base body. Here, in the sense of the present application, especially the magnetic permeability of the aforementioned auxiliary film, auxiliary structure or auxiliary layer should be understood as the magnetic permeability of the auxiliary body. Here, the magnetic permeability μ of the base body 基体 is, for example, in the range of 5 to 100, while the magnetic permeability μ of the auxiliary film or auxiliary body 辅助薄膜 is preferably in the range of 30 to 1000. Furthermore, it is preferably applicable that μ 辅助薄膜 is greater than a * μ 基体 , where the value of a is in the range of 2 to 20, especially in the range of 5 to 10.
[0036] Furthermore, it is advantageous if the shielding body described above is arranged in the intermediate section. Here, in some cases, the shielding body is arranged such that a certain distance is predefined in the radial direction between the shielding body and the charging conductor loop. Here, the corresponding distance is achieved, for example, by means of a PET film, in particular by means of a so-called polyimide film (Kapton-Folie), and the PET film or polyimide film is arranged between the shielding body and the charging conductor loop. Alternatively, the corresponding distance is achieved by means of a paint layer.
[0037] Independently of this, it is further preferred that, when viewed in the direction of the central longitudinal axis, the above-mentioned shielding body extends not only over the first longitudinal section but also over the second longitudinal section. Alternatively, the shielding body extends only over the second longitudinal section.
[0038] As already explained above, it is preferred that the shielding body is formed by a shielding film, or the shielding body has a conductor structure or a conductor layer, such as a metal layer or a coating. Here, the shielding film, the conductor structure or the conductor layer preferably has a thickness, a thickness or an extension in the radial direction in the range from 10 μm to 200 μm, in particular in the range from 20 μm to 100 μm. Thus, it is in particular a very thin film, conductor structure or conductor layer with a very small extension in the radial direction.
[0039] Furthermore, according to an implementation variant, the shielding film, the conductor structure or the conductor layer has a plurality of recesses or notches, such as circular, elliptical or angular holes, where the recesses preferably form perforations, which then generally extend over the entire circumference in the circumferential direction and preferably extend over the first longitudinal section, in particular only over the first longitudinal section. Here, the number of recesses is generally greater than 10, in particular greater than 50. The number of recesses is generally in the range from 50 to 1000.
[0040] According to another implementation variant, the shielding body, in particular the shielding film, the conductor structure or the conductor layer, forms a slit extending in the direction of the central longitudinal axis, which slit extends in the direction of the central longitudinal axis, in particular over the entire extension of the shielding body, the shielding film, the conductor structure or the conductor layer. According to the implementation variant, then, such a slit is supplemented by a switchable bridging circuit, which is constructed such that the slit can be bridged by the bridging circuit. That is to say, the bridging circuit bridges or shorts the two edges of the slit in the switched state.
[0041] If a shielding body and an auxiliary body are provided, then the auxiliary body is preferably located directly on the shielding body, that is to say, for example, wound around the shielding body. The shielding body is then generally closer to the central longitudinal axis than the auxiliary body.
[0042] As a replacement or supplement to the shielding body, in the case of at least one implementation variant, a switchable short-circuit conductor loop is provided. This short-circuit conductor loop is then typically arranged in the intermediate section. Further preferably, the short-circuit conductor loop has a plurality of turns, which then typically run circumferentially around the central longitudinal axis and around the battery or the substrate. In addition, preferably, the short-circuit conductor loop forms a coil, in particular a cylindrical coil, which preferably extends on the first longitudinal section, in particular only on the first longitudinal section. If the short-circuit conductor loop is in the short-circuited switched state, then the short-circuit conductor loop shields the charging conductor loop with respect to the radio conductor loop.
[0043] In addition, preferably, the above-described hearing device module has an outer sheath, coating or layer, by means of which the hearing device module is at least partially enclosed outwardly, in particular sealed outwardly against liquids. Here, for example, the corresponding outer sheath, coating or layer can be formed by dipping. Description of the Drawings

[0053] In all the figures, corresponding parts are respectively provided with the same reference numerals. Detailed Description of the Invention
[0054] In Figure 1 a binaural hearing device kit 2, which will be described exemplarily below, is schematically shown. The binaural hearing device kit 2 has two hearing devices 4, namely a hearing device 4 for the left ear and a hearing device 4 for the right ear. Here, each of the two hearing devices 4 has a plurality of components or structural components, in particular an input transducer 6 (usually a microphone), a control and data processing unit 8, and an output transducer 10 (such as a speaker).
[0055] In addition, each of the two hearing devices 4 has a hearing device module 12, which is configured to supply electrical energy to the corresponding hearing device 4. In this embodiment, the components of such a hearing device module 12 are in particular a base body 14, a charging conductor loop 16, and a radio conductor loop 18, which together with other components form the structural components of the hearing device module 12. In Figures 2 to 8 different implementation variants, the structural components of the hearing device module 12 are shown.
[0056] The common feature of these implementation variants is that the base body 14 is designed as a cylindrical base body 14 having a hollow internal space shown in Figures 5 to 8 . In the completed state of the hearing device module 12, a storage battery (or battery) 20 is arranged in this hollow internal space. In addition, in all the implementation variants shown here, the base body 14 is made of a soft magnetic material with a magnetic permeability μ 基体 such as 50 and extends along the central longitudinal axis 22.
[0057] Based on this central longitudinal axis 22, a first longitudinal section 24 extending along the central longitudinal axis 22 and a second longitudinal section 26 adjacent to the first longitudinal section 24 in the direction of the central longitudinal axis 22 can be classified into the hearing device module 12. In addition, a first radial section 30 extending along a radial direction 28 transverse to the central longitudinal axis 22, an intermediate section 32 adjacent to the first radial section 30 along the radial direction 28, and a second radial section 34 adjacent to the intermediate section 32 along the radial direction 28 can be attributed to the hearing device module 12. Here, the intermediate section 32 and the second radial section 34 respectively form a hollow cylindrical volume, and the first radial section forms a cylindrical volume. In Figure 5 this division of the sections is shown, and this division is common to almost all the implementation variants shown or described here.
[0058] Now, Figure 2 A first embodiment of a structural component having a base body 14, a charging conductor loop 16, and a radio conductor loop 18 is shown. Here, the two conductor loops 16, 18 each form a cylindrical coil having a plurality of turns, where the turns extend along the circumferential direction 36 around the central longitudinal axis 22 and around the base body 14.
[0059] Irrespective of the specific design of the hearing device module 12, the charging conductor loop 16 is part of a charging circuit 38. Here, the charging circuit 38 is preferably configured for inductively charging the battery 20. That is, the corresponding hearing device 4 is generally configured for inductive charging. In contrast, the radio conductor loop 18 is part of a transmitting and receiving unit, and the transmitting and receiving unit is typically configured for communication between the hearing devices 4 of the hearing device kit 2. Here, in this embodiment, the control and data processing unit 8, the radio circuit 40 controllable by the control and data processing unit 8, and the radio conductor loop 18 as part of the radio circuit 40 form the transmitting and receiving unit.
[0060] Now, in an implementation variant according to Figure 2 the turns of the charging conductor loop 16 are wound around the base body 14 and thus lie directly on the base body 14. Here, the turns of the charging conductor loop 16 are arranged in a first longitudinal section 24. In contrast, the turns of the radio conductor loop 18 are arranged in a second longitudinal section 26, so that when viewed in the direction of the central longitudinal axis 22, the two conductor loops 16, 18 are arranged side by side and are thus also spatially separated from each other in this way.
[0061] Here, in an embodiment according to Figure 2 the turns of the radio conductor loop 18 are wound on an auxiliary film 42 located in the intermediate section 32 and thus lie directly on the auxiliary film 42. Here, like the base body 14, the auxiliary film 42 is made of a soft magnetic material. However, the magnetic permeability μ 辅助薄膜 of the auxiliary film 42 is greater than the magnetic permeability μ 基体 of the base body 14, and in this embodiment, the magnetic permeability μ 辅助薄膜 of the auxiliary film 42 has a value of, for example, 500. In addition, in this embodiment, the auxiliary film 42 has a thickness of 100 μm.
[0062] Furthermore, according to Figure 2 the auxiliary film in its aspect is wound on a shielding film 44 having a thickness of 50 μm. The shielding film 44 is also arranged in the intermediate section 32 and is made of a conductive material, such as copper. Here, in an embodiment according to Figure 2In the case of the embodiment, when viewed in the direction of the central longitudinal axis 22, the auxiliary film 42 extends only on the second longitudinal section 26, while when viewed in the direction of the central longitudinal axis 22, the shielding film 44 extends on the first longitudinal section 24 and on the second longitudinal section 26.
[0063] In Figure 3 is shown Figure 2 a second embodiment variant of the structural components shown. Here, according to Figure 3 the shielding film 44 differs from that according to Figure 2 the embodiment in that it forms a slit 46 extending in the direction of the central longitudinal axis 22, and the slit 46 extends over the entire extension of the shielding film 44 in the direction of the central longitudinal axis 22. Here, in the shown embodiment variant, the slit 46 can be bridged or short-circuited by a switchable bridging circuit 48, wherein the bridging circuit 48 has a switch 50 that can be controlled by the control and data processing unit 8 for this purpose. Here, the control of the switch 50 is carried out as follows: when communicating using the radio conductor loop 18, the switch closes, and when charging the battery 20 using the charging conductor loop 16, the switch opens.
[0064] Irrespective of the design of the hearing device module 12, the simultaneous use of the charging conductor loop 16 and the radio conductor loop 18 is generally not provided, and in the case of some embodiment variants, the simultaneous use of the charging conductor loop 16 and the radio conductor loop 18 is excluded by structural measures and / or appropriate programming.
[0065] In Figure 4 is shown another variant of the hearing device module 12. Here, the shielding film 44 extends only on the second longitudinal section 26. Here, the shielding film 44 is supplemented by a switchable short-circuit conductor loop 52 having a plurality of turns. Starting from the central longitudinal axis 22, the plurality of turns are preferably arranged in the plane above the charging conductor loop 16, i.e., in the intermediate section 32. In order to achieve a certain radial distance between the charging conductor loop 16 and the short-circuit conductor loop 52, for example, an unpictured lacquer layer or film, such as a film made of PET, is located between them. A part of the short-circuit conductor loop 52 is again the switch 54, and the switch 54 can be controlled by the control and data processing unit 8, and the switch 54 is controlled in a manner similar to the switch 50 in the case of the embodiment according to Figure 3 the embodiment.
[0066] In Figure 5 and Figure 6 is shown a fourth embodiment variant. Here, the shielding film 44 extends not only on the first longitudinal section 24 but also on the second longitudinal section 26. Here, just as in the case of the embodiment according to Figure 2In the case of the embodiment, the shielding film 44 does not form a gap 46 and is not connected to the bridging circuit 48 according to Figure 3 Instead, the shielding film 44 has perforations 56 in the first longitudinal section 24, which have a plurality of recesses.
[0067] For this embodiment variant, in accordance with Figure 5 and Figure 6 Two diagrams show the field line directions of two operating modes of the relevant hearing device 4, which are the operating modes of communicating using the radio conductor loop 18 (which is shown in Figure 5 ), and the operating mode in which the coil 58 of the charging device 60 supplies power to the charging conductor loop 16. In both cases, the dashed lines roughly reproduce the general direction of one or more magnetic field lines.
[0068] In Figure 7 A fifth embodiment variant is shown. Here, the charging conductor loop 16 is directly wound around the base body 14 and is preferably fixed by pasting. The shielding film 44 is wound around the structural assembly composed of the base body 14 and the charging conductor loop 16. The shielding film 44 abuts directly against the base body 14 in the second longitudinal section 26 and abuts directly against the charging conductor loop 16 in the first longitudinal section 24 and is preferably fixedly pasted. The auxiliary film 42 is in turn wound around the shielding film 44 and is preferably pasted, and the radio conductor loop 18 is wound around the auxiliary film 42 and is preferably fixedly pasted. Here, in the case of the embodiment according to Figure 7 When looking along the direction of the central longitudinal axis 22, the auxiliary film 42 only extends on the second longitudinal section 26, while when looking along the direction of the central longitudinal axis 22, the shielding film 44 extends on the first longitudinal section 24 and on the second longitudinal section 26.
