Description

[0001] Detachable ear canal component

[0002] Modern hearing aid systems often use the receiver-in-canal (RIC) design. These RIC hearing aids are designed to offer a combination of comfort and aesthetic appeal. The system has two main components: a sound processor and a speaker, also known as the receiver. The sound processor picks up sound via one or more microphones, processes it, and amplifies it. In RIC hearing aids, these processed sound signals are transmitted electrically via a thin wire to the receiver, which sits directly in the ear canal. The receiver converts the electrical signals back into sound and delivers it into the ear canal so that it can be perceived by the wearer. A hearing system in which an actuator is placed directly on the eardrum offers several advantages, particularly in terms of sound transmission and the overall listening experience.By positioning the actuator in direct contact with the eardrum, the system can convert electronic signals into mechanical vibrations more efficiently. This direct interaction minimizes the loss of sound energy that typically occurs when vibrations are transmitted through air or additional mechanical structures, resulting in clearer and more precise sound reproduction.

[0003] Because the actuator is in direct contact with the eardrum, it typically requires less energy to generate the same sound pressure level as conventional receivers. This higher efficiency can lead to smaller batteries and longer battery life, which is both convenient and cost-effective for users. Furthermore, the overall size of the hearing system is reduced, making it more comfortable to wear and enabling new hearing system designs.

[0004] The invention relates to a hearing system according to claim 1. The dependent claims specify advantageous embodiments of the hearing system according to the invention.

[0005] The present invention relates to a system (hereinafter also referred to as the overall system, even if it may have further components in addition to the components mentioned) whose main parts are intended for placement in the ear canal and which comprises two main components: a first component which is positioned on the eardrum and remains in this position for a longer period of time (hereinafter also referred to as the eardrum component), and a second component which is located in the ear canal itself (hereinafter referred to as the ear canal component).

[0006] The design optionally includes a connecting cable between these two components or allows for a connection between the two main components in another way, e.g., optically. The system is preferably designed such that the ear canal component can be separated from the eardrum component and therefore removed from the ear canal without also removing the eardrum component. This configuration offers significant advantages in terms of user-friendliness and functionality. An alternative embodiment of the invention does not allow the two main components to be separated, but enables them to be joined together within the ear canal. Advantageously, the overall system can include additional components besides the eardrum component, the ear canal component, and optionally the connecting cable.

[0007] Preferably, at least one of the two main components has a functional element, or the main component itself is a functional element. A functional element can, for example, be a sound-receiving and / or sound-emitting component, which may serve, for instance, to implement a hearing system. Other possible functional elements whose placement in a person's ear canal is advantageous include, for example, modules for targeted drug delivery, power sources in the form of a rechargeable battery or a primary battery, electrical or optical interfaces, (signal) processors for processing and / or transmitting and / or receiving information, components for energy transmission, accelerometers, pressure sensors, or sensors for monitoring physiological parameters and / or the environment.

[0008] tympanic membrane component

[0009] Placing components directly on the eardrum in the form of a tympanostomy tube offers possibilities for improved hearing experiences and / or health monitoring. For example, the use of sound-receiving and / or sound-emitting components on the eardrum can enhance the sound experience of hearing aids. Modules such as actuators in tympanostomy tube hearing aids can deliver audio signals directly to the eardrum in the form of vibrations. Such modules are advantageously worn in the ear canal for extended periods.

[0010] Possible configurations of such a functional element, or parts thereof, include a balanced armature receiver, MEMS microspeaker, piezoelectric, electromagnetic, electrodynamic, or electrostatic loudspeaker, or another type of actuator. Sound generation can be electrostatic, electrodynamic, electromagnetic, or piezoelectric. Other possible components whose placement on the eardrum is advantageous include modules for targeted drug delivery, accelerometers, pressure sensors, or sensors for monitoring physiological parameters or the environment.

[0011] Since the tympanic membrane component may optionally be used in a potentially humid biological environment, it is advantageous if the electrical voltages, preferably DC voltages, applied to the tympanic membrane component and / or parts thereof are less than 5 volts, preferably less than 4.3 volts, and particularly preferably less than 1.3 volts. Alternatively or additionally, it is also possible to encapsulate the tympanic membrane component and / or parts thereof in a liquid-tight and / or electrically insulating manner, so that it does not come into contact with any liquid that may surround the tympanic membrane component.

[0012] It is preferred that the eardrum component has a minimum diameter smaller than the minimum diameter of the eardrum and / or a maximum diameter smaller than the maximum diameter of the eardrum. In this way, by appropriately orienting the eardrum component, it can rest completely on the eardrum without touching its edge. Preferably, these dimensions can be individually adapted to the dimensions of the eardrum of the person in whom the eardrum component is to be worn. However, it is also possible to adapt these dimensions to the average dimensions of eardrums of people of a corresponding age group or other categorized groups.Advantageously, for example, the largest diameter of the tympanic membrane component can be less than or equal to 12 mm, particularly preferably less than or equal to 10 mm, particularly preferably less than or equal to 9 mm, and particularly preferably less than or equal to 7 mm. Advantageously, the smallest diameter of the tympanic membrane component can also be greater than or equal to 3 mm, preferably greater than or equal to 5 mm.

[0013] Ear canal component: The placement of a second component in the ear canal (ear canal component) within the context of the overall system, where one component is attached directly to the eardrum, offers a variety of benefits that improve both the functionality and the user experience of the overall system.

[0014] Advantageously, the ear canal component features a strain relief mechanism. By absorbing and distributing mechanical stresses such as manipulation, pulling, or twisting, it protects the integrity of the eardrum component. This design not only prevents forces from being transmitted directly to the eardrum, thus reducing the risk of detachment or damage, but also simplifies maintenance. A user can more easily access, operate, clean, adjust, or replace this component without professional assistance, increasing the ease of use and longevity of the device.

[0015] In one embodiment of the invention, the ear canal component includes a power source in the form of a rechargeable battery or a primary battery. Placement within the ear canal facilitates energy management, whether by replacing or recharging the battery.

[0016] Advantageously, in addition to a battery, the ear canal component can also include other electrical components such as (signal) processors for processing and / or sending and / or receiving information, antennas, as well as sensors such as sound transducers like microphones or loudspeakers, temperature sensors, accelerometers or similar elements.

[0017] The ear canal component can preferably be positioned deep within the ear canal. For example, a proximal end of the ear canal component, in its intended state, can be located close to the tympanic membrane at a distance of < 15 mm, preferably < 12.5 mm, preferably < 10 mm, preferably < 7.5 mm, preferably < 5 mm and / or > 1 mm, preferably > 2 mm, preferably > 3 mm, preferably > 4 mm, preferably > 5 mm, preferably > 6 mm, preferably > 7 mm from the tympanic membrane. Advantageously, a distal end of the ear canal component can be located proximal to a distal end of the ear canal, preferably at a distance of < 5 mm, preferably < 7.5 mm, preferably < 10 mm, preferably < 12.5 mm, preferably < 15 mm and / or > 0 mm, preferably > 2.5 mm, preferably > 5 mm, preferably > 7.5 mm, preferably > 10 mm, preferably > 15 mm.

[0018] Support structure

[0019] The eardrum component and / or the ear canal component can be held in place, for example, by a retention structure within the ear canal and / or directly on the eardrum. Such a retention structure advantageously comprises or is made of a soft, adaptable material such as biocompatible silicone, polyurethane foam, or a similar material. This retention structure is advantageously designed to expand slightly after insertion and to fill the space enclosed by the ear canal and eardrum well, without exerting excessive pressure on the inner surfaces of the ear canal and eardrum, thus avoiding irritation and discomfort. Due to the flexibility of the retention structure, it advantageously adapts to different shapes and sizes of the ear canal and / or eardrum, ensuring a secure hold.

[0020] An ear canal component therefore advantageously comprises two parts: at least one retention structure and at least one core. The core of an ear canal component can include at least one further component, or at least one (further) component can form the core entirely. One embodiment of such a further component can, for example, be a functional element. Within the scope of the invention of the overall system, it is advantageous to provide at least one main component with a functional element. The functional element can thus be part of a main component.

[0021] An alternative advantageous embodiment of the retention structure is individually shaped to the user's anatomy or features interchangeable retention structures that allow for a certain degree of customization. These could be, for example, fitting pieces in various sizes that can be easily exchanged by the user. This allows the thickness and length of the retention structure to be adjusted, thus enabling a more individualized fit that takes into account individual anatomical differences in the size and / or shape of the ear canal and eardrum. This feature is crucial for a secure and comfortable fit, especially during movement or prolonged wear. In one advantageous embodiment, an interchangeable retention structure is mechanically fixed to a core. In another advantageous embodiment, an interchangeable retention structure is magnetically fixed to a core.A magnetic fixation is advantageously achieved using at least two magnetic elements.

[0022] Furthermore, the retention structure can advantageously be equipped with a smooth outer surface, allowing for easy insertion and removal without injuring the ear canal. The surface can also be advantageously coated with an antimicrobial finish to prevent earwax buildup and inhibit bacterial growth, thereby promoting hygiene and reducing the risk of infection.

[0023] Advantageously, the tympanic membrane component and / or the ear canal component can have an integrated pull tab or handle attached to one end of the respective component. This pull tab or handle allows for easy grasping, insertion, and / or removal of the respective component.

[0024] Advantageously, the ear canal component, eardrum component, and / or the retention structure are designed to be at least partially permeable to sound within a specific frequency spectrum. This allows the wearer of such a component to perceive sound sources in their environment naturally, even while wearing the components in their ear. However, it can also be advantageous to design the components in such a way that they attenuate the sound energy of a specific frequency spectrum from sound sources in the user's environment as much as possible.

[0025] Connecting Cable: The optional connecting cable can consist entirely or partially of at least one electrical conductor for transmitting electrical signals and / or power and / or at least one optical fiber for transmitting optical signals and / or power, or at least contain such an electrical conductor and / or optical fiber. Such a conductor can be made of or consist of any conceivable electrically conductive material, such as metals, in particular aluminum, copper, silver, gold, iridium, or an alloy thereof. Several wires can also be combined to form a strand, for example, to modify the flexibility of the conductor and the connecting cable. An optical fiber that is part of the connecting cable, or that is part of the cable itself, can preferably be made of a material that absorbs light of the wavelengths to be transmitted only to a small extent. Typical materials for this are quartz glass or a plastic.

[0026] The connecting cable may have or be a hose. The hose preferably comprises a chemically resistant, electrically insulating, and / or mechanically flexible material. Preferably, the hose comprises or consists of polyamide, but it may also comprise or consist of silicone or another material.

[0027] Advantageously, the tube can be filled with air or another material to a depth of at least one lumen. At least one wire and / or at least one optical fiber can be arranged within this at least one lumen of the tube.

[0028] The connecting cable can have a sheathing material, either completely or partially, which encloses at least one wire and / or at least one optical fiber. The at least one wire and / or at least one optical fiber can, for example, be embedded in the sheathing material. The sheathing material can be, for example, silicone, a thermoplastic such as polyamide, and / or an epoxy resin, but also another material or a combination of different materials. The connecting cable can advantageously contain one or more wires and / or at least one conductor, which are preferably insulated from each other and from the environment by an insulating material, preferably plastic.

[0029] In a preferred embodiment of the invention, the connecting cable is a flexible printed circuit board on a polyimide substrate with conductors configured as conductive tracks, which advantageously comprise or consist predominantly of gold. Particularly advantageously, the connecting cable is flexible or spirally wound.

[0030] The connecting cable can be used to transmit, for example, energy, audio signals, control signals, configuration data, status data, sensor data, and / or other data from the ear canal component to the eardrum component. Transmission in the reverse direction, from the eardrum component to the ear canal component, can also be advantageous within the scope of the invention.

[0031] separability

[0032] A separation and / or connection is achieved, for example, using a component connection. This connection has at least two plug components that are brought together to establish the connection. To separate the connection, the two plug components are separated. One of the plug components can be directly or indirectly connected to the ear canal component, and the other plug component can be directly or indirectly connected to the eardrum component.

[0033] The ability to detach the ear canal component from the eardrum component, as well as to remove the ear canal component from the ear canal, addresses several practical considerations that benefit the user experience and the functionality and efficiency of the device. Firstly, the removable ear canal component facilitates regular maintenance, including cleaning and hygiene measures, which are beneficial for preventing infections and ensuring user comfort and functionality. This is particularly advantageous because the ear canal is very sensitive and prone to earwax buildup.

[0034] Furthermore, the removable ear canal component in some possible configurations of the overall system increases flexibility in terms of energy management. It allows easy access for replacing or recharging any battery, ensuring that the device can be operated continuously without requiring removal or adjustment of the eardrum component.

[0035] Furthermore, the removable ear canal component simplifies repairs, upgrades, or replacements. With technological advancements, this feature allows for the integration of newer technologies or the replacement of individual components without affecting the eardrum component or requiring its removal.

[0036] Furthermore, its removability is an advantage for medical accessibility. It allows a medical professional to perform examinations and procedures on the ear without interference from the device, thus ensuring that medical care is not compromised by the presence of the eardrum component.

[0037] The ability to separate the ear canal component from the eardrum component is particularly advantageous if the separation can be carried out non-destructively and is reversible, i.e., if after separation the same, possibly modified or a different ear canal component can be reconnected to the eardrum component and placed back in the ear canal.

[0038] Connection outside the ear canal

[0039] A component connection can be implemented in various ways. One possibility is to use a reversible, manual plug connection between the ear canal component and the eardrum component. This solution requires a connecting cable to the eardrum component, which must be sufficiently long to allow the ear canal component to be removed from the ear canal in order to manually disconnect the component. The manual plug connection is therefore made between the connecting cable and the ear canal component.

[0040] The manual plug connection is advantageously designed to create a secure yet easily assembled and / or disassembled connection between the two components. Advantageously, the connection can be assembled and / or disassembled without special tools.

[0041] The manual plug connection can advantageously include a simple rotary, locking function and / or snap-in device, in which a first plug connection component (plug) is pressed against a second plug connection component (socket) until, for example, a click is heard, signaling a secure connection.

[0042] Magnetic interface

[0043] An alternative embodiment of the component connection between the ear canal component and the eardrum component can provide for the use of a magnetic interface. The design of a magnetic interface comprises at least two magnetic elements. These can contain or be either permanent magnets or electromagnets, with the use of a permanent magnet being advantageous. Permanent magnets can, for example, comprise or consist of iron, cobalt, nickel, neodymium, samarium, and / or other ferrites and / or rare earth elements and / or other hard magnetic materials or a combination of these materials. A variant of the invention can include magnetic elements that preferably comprise or consist of a ferromagnetic material with soft magnetic properties, such as iron, silicon-enhanced steels, iron-nickel alloys, iron-cobalt alloys, and other iron and steel alloys, but which are not permanent magnets.In this case, the corresponding counterpart in the other connector component can be a permanent magnet or electromagnet. Therefore, at the magnetic interface, preferably at least one of the following variants is present: a) One connector component has at least one permanent and / or electromagnet, and the other connector component has at least one ferromagnetic element. b) One connector component has at least one permanent and / or electromagnet, and the other connector component also has at least one permanent and / or electromagnet, wherein the poles of the magnets are aligned in the intended position for the connected plug connection such that an attractive force prevails between the magnet(s) of one connector component and the magnet(s) of the other connector component.

[0044] A magnetic interface preferably accommodates two connector components: One connector component can be part of or connected to the eardrum component, and the other connector component can be part of or connected to the ear canal component.

[0045] A preferred part of the invention is a variant in which one connector component is part of the connecting cable and the other connector component is part of either the eardrum component or the ear canal component. Each connector component contains at least one magnetic element. In a preferred embodiment, at least two magnetic elements are configured such that they are suitable together for the magnetic and / or electromagnetic transmission of signals and / or energy.

[0046] Additional magnetic field

[0047] An alternative embodiment of the invention preferably uses an electromagnetically detachable connection. In this configuration, the ear canal component and the eardrum component can be connected to each other via a magnetic interface. To detach the component connection, an electromagnet is used to generate an oppositely polarized magnetic field at this interface, which causes the connection to break. Compared to a manual plug connection, this has the advantage that a long connecting cable between the ear canal component and the eardrum component is unnecessary, since the connection can be made and detached within the ear canal.

[0048] In an alternative embodiment of the invention, this connection can be configured such that switching on the electromagnet establishes the connection and switching it off disconnects it. However, this would require a constant current flow if the connection is to remain intact.

[0049] ejector

[0050] An alternative embodiment of the invention advantageously also features a magnetic interface for connecting the ear canal component and the eardrum component. Instead of an electromagnet, an ejector is used to release the connection, which is actuated from outside the ear canal. The ejector mechanically disconnects the magnetic interface between the ear canal component and the eardrum component, so that the ear canal component can be removed from the ear canal without having to detach the eardrum component from the eardrum.

[0051] Self-locating magnetic interface

[0052] In an alternative design, the magnetic interface can be dimensioned so strongly that the connector components automatically align themselves within the ear canal. At the same time, it is advantageously weak enough that pulling on the ear canal component releases the connection without detaching the eardrum component from the eardrum or exerting any other undesirable force on it. This approach also eliminates the need for a long connecting cable. However, the challenge here lies in dimensioning and positioning the magnetic elements in a way that meets both of the aforementioned requirements for the strength of the component connection.

[0053] Switchable magnetic interface

[0054] In an alternative embodiment of the invention, the magnetic interface can contain at least one magnetic element, which preferably contains or consists of a permanent magnet or a ferromagnetic element, and thus serves to create and maintain the component connection.

[0055] Advantageously, at least one magnetic element is contained within the ear canal component. This magnetic element can be designed to be mechanically movable and manipulated externally by an electromagnet or permanent magnet. When an external magnetic field is applied, for example by bringing a permanent magnet close or switching on an electromagnet, the magnetic element is moved away from the opposing connector component by the force thus generated, thereby reducing the magnetic locking force of the magnetic interface and allowing the component connection to be released. Preferably, the magnetic element is spring-loaded and returns to its original position as soon as the external magnetic field is weakened or removed.

[0056] In an alternative embodiment of the invention, applying an external magnetic field, due to its orientation, can lead to a reduction in the attractive force between the two connector components, thereby enabling the magnetic interface to be released. Advantageously, applying an external magnetic field with a corresponding orientation can also increase the magnetic locking force, thus enabling the magnetic interface to be established.

[0057] radially polarized magnets

[0058] An alternative embodiment of the invention advantageously uses diametrically or multiradially polarized permanent magnets in one or both connector components. This allows an attraction or repulsion between the connector components, and thus the establishment or release of the magnetic connection, to be achieved by rotating one of the diametrically or multiradially polarized permanent magnets.

[0059] External module and connecting link

[0060] In an alternative embodiment of the invention, the function of the ear canal component can be that of an interface to an external module located further out on the ear. For this purpose, the overall system preferably has a connecting element to which an external module can be coupled. The connecting element can be part of the ear canal component.

[0061] In another advantageous embodiment of the invention, the connecting element can be connected to the eardrum component via a connecting cable. The ear canal component then acts as a strain relief. A connection between the external module and the connecting element can be established and released, thus reducing or preventing any resulting force on the eardrum module and, for example, preventing it from being moved from its intended position. The connecting element can be used to transmit, for example, energy, audio signals, control signals, configuration data, status data, and / or other data from the external module to the ear canal component and / or the eardrum component. Transmission in the reverse direction from the ear canal component and / or the eardrum component to the external module can also be advantageous within the scope of the invention.

[0062] implementation

[0063] In an advantageous embodiment of the invention, the connecting cable can be routed through a designated opening in the ear canal component or past the ear canal component, so that the connecting element is positioned on one side (laterally) and the tympanic membrane component on the other side (medially) of the ear canal component when the components are arranged in their intended position in the ear canal. In this embodiment, a mechanical connection between the connecting cable and the ear canal component is intended for strain relief. Alternatively, this routing of the connecting cable can also serve to establish an electrical connection between the connecting cable and the ear canal component on the lateral side of the ear canal component.

[0064] Anchoring system

[0065] Advantageously, the ear canal component can have an anchoring system with which the connecting cable is attached to the ear canal component and / or electrically connected. Advantageous features of the anchoring system include ensuring durability, safety, and easy installation while simultaneously minimizing stress on the cable during use.

[0066] An advantageous embodiment of the anchoring system features a mechanical fastening system in which one end of the connecting cable is fitted with a male connector that securely engages in a female receptacle within the ear canal component. This type of connection can, for example, be a bayonet fitting, where the plug is inserted and twisted into a locked position. This twist-lock mechanism ensures a quick, secure connection that withstands tensile and torsional forces without loosening.

[0067] Alternatively, a magnetic interface can be used to attach the connecting cable to the ear canal component. The end of the connecting cable and the corresponding part of the ear canal component can contain embedded magnetic elements that naturally align and connect when brought close together.

[0068] Stop component

[0069] An advantageous embodiment of the invention may include a stop component. This stop component may be rigidly connected to the connecting cable and lie medially against the ear canal component when the ear canal component and the tympanic membrane component are arranged in their intended position in the ear canal. Among other things, this stop component allows manipulation, pulling, or rotation of a connecting element without the resulting or transmitted force being transferred to the tympanic membrane component in a manner detrimental to its placement.

[0070] crimp connection

[0071] Alternatively, the anchoring system can be implemented by plastically deforming a corresponding crimp structure on the ear canal component. For this purpose, the connecting cable is attached to the ear canal component using a dedicated tool, for example, by crimping or folding the crimp structure. In an advantageous embodiment, the tool can be configured to cut the cable to length during the crimping process, i.e., when crimping or folding the crimp structure. For example, if the tool is in the form of pliers with jaws at the ends of which elements are provided for crimping or folding the crimp structure, cutting edges can be provided on the jaws between the elements and a joint connecting the jaws. These cutting edges cut the cable when the jaws are moved towards each other for crimping or folding.

[0072] A crimp connection is only partially reversible and may require suitable tools for repairs.

[0073] Alternatively, the connecting cable can also be attached to the ear canal component using a fastening component. This fastening component can be an adhesive bond, clamping bolt, screw, rivet, plug connector, or similar component.
