Description

[0001] The invention relates to a hearing aid comprising a device housing with a battery compartment and an antenna element. The invention further relates to an antenna element for such a hearing aid.

[0002] A hearing aid is generally defined as an electronic device that supports the hearing ability of a person wearing it. In particular, the invention relates to a hearing aid designed to fully or partially compensate for the hearing loss of a hearing-impaired user. Such a hearing aid is also referred to as a "hearing aid" (HA). In addition, there are hearing aids that protect or improve the hearing ability of users with normal hearing, for example, by enabling improved speech understanding in complex listening situations. Such devices are also referred to as "personal sound amplification products" (PSAPs). Finally, the term "hearing aid," as used here, also includes headphones worn on or in the ear (wired or wireless, and with or without active noise cancellation), headsets, etc., as well as implantable hearing aids, such as cochlear implants.A hearing aid can also be part of an AR system (AR: Augmented Reality) or VR system (VR: Virtual Reality) to output the acoustic information of a virtual sound source to the user.

[0003] Hearing aids in general, and hearing assistance devices in particular, are usually designed to be worn on the head, specifically in or on one of the user's ears, particularly as behind-the-ear (BTE) or in-the-ear (ITE) devices. With regard to their internal structure, hearing aids typically have at least one output transducer that converts an input audio signal into a signal perceptible to the user as sound, and then outputs this signal to the user.

[0004] In most cases, the output transducer is an electro-acoustic transducer that converts the (electrical) output audio signal into sound waves, which are then delivered into the user's ear canal. In a behind-the-ear (BTE) hearing aid, the output transducer, also known as the receiver, is usually integrated outside the ear within the hearing aid housing. In this case, the sound emitted by the output transducer is guided into the user's ear canal via a sound tube. Alternatively, the output transducer can also be located within the ear canal, and thus outside the behind-the-ear housing. Such in-the-canal (ITE) hearing aids are also known as RIC devices, short for "Receiver In Channel."Hearing aids worn in the ear, which are so small that they do not protrude beyond the ear canal, are also called CIC devices (after the English term "Completely in Canal").

[0005] In other designs, the output transducer can also be an electromechanical transducer that converts the output audio signal into structure-borne sound (vibrations), which is then transmitted, for example, to the user's skull bones. Furthermore, there are implantable hearing aids, particularly cochlear implants, and hearing aids whose output transducers directly stimulate the user's auditory nerve.

[0006] In addition to the output transducer, a hearing aid often has at least one (acousto-electrical) input transducer. During operation, the input transducer(s) pick up sound waves from the environment surrounding the hearing aid and convert these waves into an input audio signal (i.e., an electrical signal that carries information about the ambient sound).

[0007] This input audio signal – also referred to as the “recorded sound signal” – is regularly output to the user in its original or processed form, e.g. to implement a so-called transparency mode in headphones, for active noise suppression, or – e.g., in a hearing aid – to achieve improved sound perception for the user.

[0008] Furthermore, a hearing aid often includes a signal processing unit (signal processor). In the signal processing unit, the input audio signal(s) are processed (i.e., modified with respect to their sound information). The signal processing unit then outputs a correspondingly processed audio signal (also referred to as the "output audio signal" or "modified sound signal") to the output converter and / or to an external device.

[0009] Hearing aids are generally powered by batteries as their internal energy storage. The hearing aid housing has a battery compartment to hold the battery, which is covered by a battery compartment door or flap, thus protecting it from the environment. The battery can be inserted into and removed from the battery compartment through the battery compartment door.

[0010] Hearing aids are preferably designed to be particularly space-saving and compact, so that they can be worn as discreetly as possible. This has led to the production of increasingly smaller hearing aids, which offer greater wearing comfort and are therefore barely noticeable to the user when worn in or on the ear. However, due to the reduced installation space, it is becoming increasingly difficult to accommodate and / or integrate conventional antenna elements for wireless signal transmission into such hearing aids.

[0011] For this purpose, it is possible, for example, to integrate the antenna element onto or into a foldable or bendable printed circuit board as a so-called flexible printed circuit board antenna (FPCA).

[0012] These types of circuit board antennas are flexible and can therefore be bent relatively easily, making them comparatively easy to arrange inside the hearing aid housing. However, these flexible circuit board antennas are comparatively expensive.

[0013] Alternatively, it is possible, for example, to integrate the antenna element onto a (non-foldable or non-bendable) circuit board, especially a mainboard (motherboard), as a so-called motherboard ground antenna (MBGA). However, such an antenna element is limited by the size and layout of the circuit board, so that adapting it to different form factors of the device housing is often not possible without corresponding modifications to the circuit board.

[0014] It is also possible to use a wire antenna as an antenna element. However, such wire antennas are not suitable for the RIC form factor due to their fixed wire length, thus limiting their use to the BTE or HTE form factor.

[0015] From DE 10 2017 208 445 A1, it is known to design the antenna element as an electrically conductive housing part of the hearing aid housing made of carbon fibers. The housing part forming the antenna element can, for example, be a battery compartment door.

[0016] US patent 11,122,376 B2 discloses a RIC hearing aid with an antenna element integrated into or attached to the battery compartment door. The antenna element is magnetically fed by a separable transformer located at the transition to the device housing.

[0017] US patent 11,659,342 B2 describes an antenna element with two antenna arms. The antenna arms are applied as conductive traces to two housing parts, which are articulated together by a hinge pin. The hinge pin provides an electrically conductive connection between the antenna arms.

[0018] From EP 3 110 175 A1, a hearing aid with an antenna unit is known. The hearing aid includes a transmission line that connects a communication unit and the antenna unit, or is at least part of a connection between the communication unit and the antenna unit. The antenna unit is at least partially embedded in a battery compartment of the hearing aid.

[0019] US 2023 / 0336928A1 describes a hearing aid with a primary contact surface. A battery housing of the hearing aid includes a primary mounting interface and a battery compartment configured to receive a battery. The battery housing has a shape that matches that of the battery compartment. A front panel includes a secondary mounting interface configured to couple with the primary mounting interface of the battery housing, and a secondary contact surface configured to engage snugly with the primary contact surface of the housing. A flexible printed circuit board assembly is supported by an outer surface of the battery housing and / or the front panel.

[0020] US patent 2019 / 0076662A1 describes a multi-component system comprising a first component with a first conductive pad, a second conductive pad, and a first section of a loop antenna that terminates on one side at the first conductive pad and on the other side at the second conductive pad. The multi-component system further comprises a second component with a third conductive pad, a fourth conductive pad, and a second section of the loop antenna that terminates on one side at the third conductive pad and on the other side at the fourth conductive pad.The second component is different from the first component and is configured to be detachably coupled to the first component, such that the first and third conductive pads, as well as the second and fourth conductive pads, each form first and second non-galvanic couplings that capacitively couple the first and second sections of the loop antenna, while the sections of the loop antenna remain galvanically isolated.

[0021] The invention is based on the objective of providing a particularly suitable hearing aid. In particular, a hearing aid with an antenna element is to be provided that can be used cost-effectively and flexibly for different housing form factors. The invention is further based on the objective of providing a particularly suitable antenna element.

[0022] The problem is solved according to the invention with respect to the hearing aid by the features of claim 1 and with respect to the antenna element by the features of claim 10. Advantageous further developments and embodiments are the subject of the dependent claims. The advantages and embodiments mentioned with respect to the hearing aid are also transferable to the antenna element and vice versa.

[0023] The hearing aid according to the invention is in particular designed as a behind-the-ear (BTE) hearing aid or as a receiver-in-canal (RIC) hearing aid.

[0024] In this context, a hearing aid refers specifically to an electronic device for outputting an audio signal, such as speech or music, like a headset, headphones, earphones, or music player. Preferably, the hearing aid is a hearing aid (HA), meaning an electronic device that, when in use, supports the hearing of the wearer (user or wearer of the hearing aid). The hearing aid is specifically designed to at least partially compensate for the hearing impairment of a hearing-impaired user. Other types of hearing aids aim to support the hearing of users with normal hearing, i.e., to improve speech perception in complex acoustic situations.

[0025] The hearing aid consists of a housing with a battery compartment and a battery compartment door (battery compartment cover) that closes the battery compartment. The battery compartment door is hinged to allow it to pivot on the housing. The hearing aid also includes an antenna element for wireless signal communication.

[0026] According to the invention, the antenna element comprises a housing section and a door section, which, during antenna operation, form the signal-transmitting and / or signal-receiving areas of the antenna element. The housing section is located on the housing side, i.e., within the device housing, with the door section extending at least partially over the battery compartment door. Preferably, the door section is at least partially integrated into the battery compartment door. The housing section and the door section are electrically connected to the antenna element via a sliding contact arranged at the hinge. This results in a particularly suitable hearing aid.

[0027] In a preferred embodiment, the door section has a sliding contact head arranged on the hinge, particularly on the door-side hinge strip, which is hinge-like and sits in a contact socket of the housing section, with which it is in sliding contact. The sliding contact head and the contact socket are designed as electrically conductive surfaces that are in contact with each other, thus electrically connecting the door section and the housing section. For example, the contact socket and the sliding contact head are designed as metal coatings. In particular, a concave inner surface of the contact socket facing the door-side hinge strip is in sliding contact with a convex outer surface of the sliding contact head. The housing section is thus electrically connected to the contact socket, and the door section is electrically connected to the sliding contact head.The electrical connections between the contact pan and the housing section and / or the sliding contact head and the door section are, for example, designed as soldered or welded connections.

[0028] This design simplifies the manufacturing process of the hearing aid, as the respective positions for the contact cup and / or the sliding contact head are freely accessible when the device housing and battery compartment door are not assembled. For example, it is therefore possible to manufacture the contact cup and / or the sliding contact head by applying a metal coating to the corresponding positions. This makes it possible to produce a particularly cost-effective hearing aid.

[0029] In an advantageous embodiment, the hinge comprises a housing-side hinge and at least one door-side hinge, which are rotatably or pivotably coupled to each other via a hinge pin. Preferably, two door-side hinges are integrally formed with the battery compartment door, which engage the at least one housing-side hinge on both sides. The hinges are jointly penetrated by the hinge pin and are thus mechanically coupled to each other. The sliding contact head is arranged radially on the outside of the door-side hinge, i.e., on its outer surface.

[0030] In an advantageous embodiment, the door section extends in an approximately U-shape along the back of the battery compartment door between the hinge and a handle. The handle facilitates manual opening and closing of the battery compartment door. The short leg (horizontal leg) of the door section is at least partially integrated into the handle, while the long legs (vertical legs) run parallel to each other along the back. This increases the length of the door section and thus the length of the antenna element (antenna length). Preferably, each free end of the long leg is connected to a sliding contact head, in particular by soldering or welding.

[0031] In a preferred embodiment, the housing section is configured as a wire, for example a copper wire, particularly an insulating wire, and the door section as a metal surface, for example a metal strip or foil. Thus, the housing section is essentially configured as a wire antenna, while the door section is configured as a flexible, for example stamped, antenna. The housing section and the door section are therefore configured as different types of antennas. Preferably, however, the sections are made of the same material, for example copper.

[0032] Preferably, the insulation of the wire at the wire ends is removed (stripped) in the housing section, with the exposed wire ends being, for example, tinned, in order to easily solder them to the contact pan on one side and to a main circuit board (signal processing unit) of the hearing aid on the other.

[0033] For example, the metal surface is designed as a copper strip, specifically a self-adhesive copper strip. This allows the door section to be easily attached (glued) to the inside of the battery compartment door, eliminating the need for additional retaining contours on the battery compartment door for the door section.

[0034] In a preferred further development, the hearing aid features a mounting frame (electronic frame, frame) for receiving and holding electrical or electronic components or assemblies within the device housing. The mounting frame is, for example, designed as an injection-molded MID component (MID: Molded Interconnected Devices).

[0035] The housing section is guided, at least in part, by the support frame. This guidance of the housing section on the support frame allows for the necessary antenna length for effective transmit / receive characteristics of the antenna element, even in compact hearing aids.

[0036] To guide the housing section, which is designed in particular as a wire antenna, the support frame has, for example, a groove-like recess as a guide groove in which the housing section is arranged in a way that prevents it from being lost.

[0037] By guiding the housing section along the support frame, a defined and immobile positioning of the housing section is ensured, which contributes to increased performance of the antenna element. Furthermore, this immobile positioning is advantageous during the manufacturing process, as it prevents unintentional contact between the housing section and other components of the hearing aid. For example, this makes it easy to insert the support frame with the housing section into the device housing.

[0038] In an advantageous further development, the hinge strip on the housing side is integrally molded onto the support frame.

[0039] In a preferred embodiment, the support frame has two connectable frame halves, with one housing section guided in each half. In other words, the (first) housing section is guided in a first frame half, and a second housing section is guided in a second frame half. The housing sections are electrically connected to each other via the door section. The antenna element thus comprises two housing sections and a door section arranged between them. The second housing section further increases the antenna length of the antenna element, enabling sufficient transmit / receive characteristics even with small housing form factors.

[0040] In principle, the number of sliding contact heads corresponds to the number of contact cups, since these each form pairs for an electrical sliding contact connection. In particular, the antenna element has at least two sliding contact heads and at least two contact cups in order to advantageously extend in a loop shape over the battery compartment door.

[0041] In one possible embodiment, the door section is arranged on the inside of the battery compartment door, i.e., on a side facing the battery, and covered with an electrically insulating layer, so that the door section is electrically isolated from a battery located in the battery compartment.

[0042] The antenna element according to the invention is designed, suitable, and configured for a hearing aid as described above. The antenna element comprises a housing section for placement within the hearing aid housing and a door section for at least partial placement above a battery compartment door of the hearing aid, which is pivotally connected to the housing by means of a hinge. The housing section and the door section are electrically connected, or connectable, via a sliding contact located on the hinge. The antenna concept according to the invention is suitable for both behind-the-ear (BTE) and receiver-in-canal (RIC) hearing aids, allowing for cost-effective implementation in both form factors.

[0043] The invention is explained in more detail below with reference to a drawing. The drawing shows: Fig. 1 In a schematic side view, a hearing aid in the form of a behind-the-ear hearing aid, with a device housing and a battery compartment door, Fig. 2 in perspective view the hearing aid without the device housing, Fig. 3.

[0044] Corresponding parts and sizes are always marked with the same reference symbols in all figures.

[0045] The Fig. Figure 1 shows the basic structure of a hearing aid 2 according to the invention. The hearing aid 2 is here designed as an example of a behind-the-ear (BTE) hearing aid.

[0046] The hearing aid 2 includes, as described in the Fig. Figure 1 schematically depicts a device housing 4 in which several microphones, also referred to as (acousto-electrical) input transducers 6, are installed. In this embodiment, the hearing aid 2 has at least two input transducers 6.

[0047] The input transducers 6 capture (airborne) sound or acoustic signals in the vicinity of the hearing aid 2 and convert them into electrical, in particular multi-channel, input signals E1, E2. Preferably, the input signals E1, E2 have several frequency channels, for example 48 channels in the frequency range between 0 kHz and 28 kHz.

[0048] A signal processing unit 8, also integrated into the device housing 4, processes the input signals E1 and E2. An output signal A from the signal processing unit 8 is transmitted to an output transducer 10, which is, for example, an electro-acoustic transducer and is designed as a loudspeaker or receiver, and which outputs an acoustic signal. In the hearing aid 2, the acoustic signal is transmitted to the eardrum of the hearing aid user, possibly via a sound tube (not shown in detail here) or an external receiver with an earmold that sits in the ear canal. However, an electromechanical output transducer, such as in a bone conduction receiver, is also conceivable as the receiver.

[0049] For example, a carrying hook (hearing aid bracket) 11 is attached to the device housing 4 ( Fig. 2 and Fig. 3) arranged by means of which the device housing 4, and thus the hearing aid 2, is held against the ear. The carrying hook 11 connects the device housing 4 to the sound tube or the external receiver.

[0050] The hearing aid 2, and in particular the signal processing unit 8, is powered by a battery 12 integrated into the device housing 4. The battery 12, for example a button cell, is housed in a battery compartment 14. To repeatedly close the battery compartment 14, the hearing aid 2 includes a "cover" referred to as the battery compartment door 16, which is pivotally attached to the housing 4 by a hinge 18, similar to a flap or door.

[0051] The signal processing unit 8 of the hearing aid 2 is also designed and intended for wireless communication with a device separate from the hearing aid 2, for example, with a second hearing aid (not shown in detail). For this purpose, the hearing aid 2 includes an antenna element 20, which is designed and intended for transmitting and receiving (wireless) communication signals.

[0052] To save space within the hearing aid 2, the antenna element 20 is divided into a housing section 22 and a door section 24. In the assembled state, the housing section 22 is located inside the device housing 4, while the door section 24 is located on the battery compartment door 16. The housing section 22 and the door section 24 are electrically connected to each other via an electrical sliding contact 26 on the hinge 18.

[0053] The following is a description of the construction of hearing aid 2 based on the Fig. 2 to 6 explained in more detail.

[0054] The Fig. Figure 2 shows the hearing aid 2 without the device housing 4 and with a partially transparent battery compartment door 16. The hearing aid 2 has a support frame 28 arranged in the device housing 4 for holding electrical components. In the illustrated embodiment, the support frame 28 has two compound frame halves 28a, 28b. As shown, for example, in the illustration of the Fig. As can be seen in Figure 2, the frame halves 28a and 28b form the internal battery compartment 14 for holding the battery 12.

[0055] The frame halves 28a and 28b each have a one-piece molded hinge strip 30 to form the hinge 18.

[0056] The hinge 18 further comprises two hinge bands 32, each integrally molded onto the battery compartment door 16. As in the Fig. As can be seen relatively clearly in Figure 2, the hinge bands 32 encompass the hinge bands 30 of the frame halves 28a and 28b, so that the hinge bands 32, 30 are stacked on top of each other.

[0057] The hinge bands 30, 32 are penetrated by a common hinge pin 34 of the hinge 18 and are thus mechanically coupled to each other. The battery compartment door 16 is therefore coupled to the support frame 28 by means of the hinge 18. The pin-like hinge pin 34 does not contribute to an electrical connection between the door section 24 and the housing section 22. The hinge pin 34 is therefore not part of the sliding contact 26. The hinge pin 34 is made, for example, of plastic or metal.

[0058] In the assembled state of the hearing aid 2, the hinge 18 is essentially completely arranged inside the housing 4, so that at least the hinge bands 30, 32 are not accessible from the outside.

[0059] The in Fig. In this embodiment, the antenna element 20, shown separately, has two housing sections 22a and 22b, each of which is connected to the door section 24 by means of a sliding contact 26. In other words, the door section 24 connects the housing sections 22a and 22b to each other.

[0060] The (first) housing section 22a is guided in frame half 28a, and the (second) housing section 22b is guided in the other frame half 28b. The housing sections 22a and 22b are arranged, in particular, on opposite sides of the support frame 28. To guide the housing sections 22a and 22b, the support frame 28 and the frame halves 28a and 28b, respectively, have groove-like recesses as guide grooves 36 in which the respective housing section 22a and 22b is arranged to prevent loss.

[0061] Housing sections 22a and 22b are each designed as a wire and a wire antenna, respectively, so that they can be easily placed in the guide grooves 36. Specifically, housing sections 22a and 22b are formed by an insulating wire, the insulation of which is removed (stripped) at the wire ends for electrical contact with a main circuit board (signal processing unit 8) and the sliding contact 26. To improve these soldered connections, the wire ends are, for example, tinned.

[0062] In a behind-the-ear version of hearing aid 2, the battery compartment door 16 forms a closed position - as in Fig. 1 shown - an end section or case bottom of case 4. The in Fig. The battery compartment door 16, shown separately with door section 24, is designed in the form of a slightly curved rectangle and, when closed, extends perpendicularly to a cover surface of the housing 4 in the width direction from one narrow side of the housing 4 to the other. The battery compartment door 16 has two cover surfaces 38 which, when closed, are flush with the cover surfaces of the housing 4.

[0063] For pivoting the connection of the battery compartment door 16 to the housing 4 or the support frame 28, two molded hinge strips 32 project from one of its longitudinal ends 40. At the opposite longitudinal end 42, the battery compartment door 16 has a molded, raised handle 44 for simplified manual opening and closing. When the battery compartment door 16 is closed, the handle 44 runs, for example, parallel to the narrow side of the housing 4.

[0064] The battery compartment door 16 also has a (battery compartment, door) back 46 which connects the cover surfaces 38 vertically and forms an end face of the housing 4 when closed.

[0065] The battery compartment door 16 is manufactured entirely, i.e., in one piece or monolithically, from a single material, specifically injection-molded plastic. The door section 24 is integrated into the battery compartment door 16 or arranged on the inside of the battery compartment door 16, i.e., on a side facing the battery 12, and is covered, for example, with an electrically insulating layer, so that the door section 24 is electrically insulated from the battery 12 located in the battery compartment 14.

[0066] The door section 24 extends in an approximately U-shape along the back 46 between the hinge 18 and the handle tab 44. The door section 24 has two parallel long U-shaped legs 48, which are connected transversely to each other by a short U-shaped leg 50. The short U-shaped leg 50 is at least partially integrated into the handle tab 44, so that it is angled or bent perpendicularly with respect to the long U-shaped legs 48.

[0067] The door section 24 is designed in particular as a metal surface, for example as a molded part or as a metal foil.

[0068] The free ends of the U-shaped long legs 48 are guided from the inside of the door to the radially outer surfaces of the hinge bands 32, i.e., the side of the hinge bands 32 facing the support frame 28, via connecting sections 52. The convex outer surfaces of the hinge bands 32 are coated with a metal coating, which forms a sliding contact head 54 for the sliding contact 26. The connecting sections 52 are electrically connected to the respective sliding contact head 54, for example, by soldering.

[0069] In the assembled state of the hinge 18, the sliding contact heads 54 engage in a hinge-like manner in a cup-shaped concave recess of the frame halves 28a, 28b. The recesses, which are not further specified, are each provided with a metal coating, which – as, for example, in Fig. 3 and Fig.4. Contact cups 56 for the sliding contacts 26 are formed, which are relatively clearly visible. The sliding contact heads 54 bear against the contact cups 56 with a mechanical contact, so that an electrically conductive sliding contact is formed between the conductive surfaces.

[0070] The contact cups 56 are each contacted with one of the housing sections 22a, 22b and electrically connected. In particular, the ends of the housing sections 22a, 22b are soldered to the contact cups 56.

[0071] The claimed invention is not limited to the embodiments described above. Rather, other variants of the invention can also be derived by a person skilled in the art within the scope of the disclosed claims without departing from the subject matter of the claimed invention. In particular, all individual features described in connection with the various embodiments can also be combined in other ways within the scope of the disclosed claims without departing from the subject matter of the claimed invention.

[0072] The hearing aid 2 can also be designed as a receiver-in-the-canal hearing aid. It is essential that the antenna element 20 is divided into at least one housing section 22 and at least one door section 24 with sliding contact in a housing or battery compartment door 16.
