[0020] In another aspect, one or more of the above objects are achieved by a tool.

[0021] The present invention relates to different aspects, including the tools described above and below, and is configured to be used with a corresponding hearing device, a binaural hearing device, a larger and / or smaller hearing device, a more advanced or less advanced (e.g. with more or fewer functions) hearing device, a system, a method, a device, a use and / or a product device for helping a person with hearing loss and / or any other device configured to be used and / or used in conjunction with a hearing device, each producing one or more of the benefits and advantages described in conjunction with the second mentioned aspect, and each having one or more embodiments corresponding to the embodiments described in conjunction with the second mentioned aspect and / or disclosed in the appended claims.

[0022] According to the present invention, at least one of the objects is achieved by a tool for replacing a cover of a hearing device according to the above and / or below, the hearing device comprising a hearing device housing, the tool comprising a handle with a first fixing pin for pushing out a locking pin for detachably connecting the cover and the hearing device housing, wherein the handle further comprises a second detachable pin which can replace the locking pin and thus detachably mate the cover and the hearing device housing. An advantage of such a tool is that it is easy to reach and hold / grip. Another advantage is that its pins, in particular detachable pins, are easy to keep track of and the risk of loss is eliminated or at least reduced.

[0023] In some embodiments, the locking pin and the second detachable pin are of substantially the same size. Both these pins above and below are used to detachably lock the cover and the housing together to form a hearing device. Another advantage is that the detachable pin is easy to keep track of and eliminates or at least reduces the risk of loss.

[0024] In some embodiments, the locking pin and the second removable pin are made of the same material. Thus, they can be easily manufactured on the same machine and easily recycled in the same way, as there is no need to store and handle different materials. According to some embodiments, the second removable pin is attached to the tool handle by a second friction force. Thus, the advantage is that the removable pin is easy to track and the risk of it coming loose is eliminated or at least reduced, without being difficult / hard to separate from the tool.

[0025] According to some embodiments, the second friction force is lower than the first friction force. Therefore, the advantage is that the removable pin is easy to remove from the tool while being firmly held by the tool until it is to be removed. In some embodiments, the second friction force is greater than the gravity acting on the second removable pin. The advantage is that the removable pin is easy to remove from the tool while being firmly clamped by the tool until it is removed and will not loosen due to inadvertent means, or at least will not be easily loosened due to inadvertent means. According to some embodiments, the tool handle includes a retainer / bushing for the second removable pin. Therefore, the advantage is that the removable pin is easy to separate from the retainer / bushing of the tool while being firmly held by the retainer / bushing until it is to be separated and will not loosen due to inadvertent means. According to some embodiments, the retainer / bushing of the tool is made of plastic and / or rubber. Therefore, the advantage is that the grip of the bushing for removably holding the second pin is easy to maintain and / or optimize.

[0026] According to some embodiments, the tool comprises a removable protective cap configured to cover the second removable pin when attached to the tool handle. Thus, an advantage is that the removable pin is protected from separation from the tool because the cap securely covers it until it is to be removed and cannot accidentally come loose, or at least is not easily loosened by inadvertent means because the cap must first be removed. According to some embodiments, in the tool, the removable protective cap is transparent. Thus, an advantage is that it is easy to see the removable pin before removing it from the tool so that it can be checked whether it has accidentally come loose. In some embodiments, the tool is elongated. An advantage of such an elongated tool is that it is easy for a user's hand / user's palm to hold / grip.

[0027] According to some embodiments, the tool comprises a removable protective cap configured to cover the second removable pin and / or the first fixed pin when attached to the tool handle. The second removable pin has the advantage that there is no risk of it falling off the handle if accidentally loosened, and the user is protected from being stabbed / punctured by the second removable pin because the second removable pin is securely covered by the cap, or at least the risk of such injury is reduced, since the cap must be removed before the second removable pin is exposed. The first fixed pin has the advantage that the user is protected from being stabbed / punctured by the first fixed pin because the first fixed pin is securely covered by the cap, or at least the risk of such injury is reduced, since the cap must be removed before the first fixed pin is exposed (again).

[0028] According to some embodiments, the tool includes a handle having a first fixing pin for pushing out a locking pin, the locking pin detachably connecting a cover and a hearing device housing, wherein the handle also includes a second detachable pin, which can replace the locking pin to detachably fit the cover and the hearing device housing, and a detachable protective cap, the detachable protective cap being configured to detachably cover the second detachable pin when attached to the tool handle in a first mode, the handle and the cap being configured with each other so that the cap detachably covers the first fixing pin in a second mode after the first fixing pin is used to push out the locking pin and the second pin is detachably assembled.

[0029] The advantage is that since the first fixing pin is securely covered by the cap, the user will not be stabbed / punctured by the first fixing pin, or at least the risk of such injury is reduced, since the cap must first be removed before the first fixing pin is exposed again. In some embodiments, the first fixing pin is arranged at the end of the tool opposite to the end where the second pin is located before it and the cap is separated. Therefore, after the first fixing pin is used to push out the locking pin, the cap is moved to the other tool end and detachably assembled on the first fixing pin, so that when the user pushes the handle when assembling the second pin, when pushing the handle to introduce / push the second pin into the hearing device so that its cover and housing cooperate when the cap covers it, there is no risk of any part of the hand being stuck on the fixing pin. The cap can be cup-shaped, the bottom of which covers the protruding end of the first fixing pin and / or the second removable pin in the radial direction of the handle and at least the entire protruding and exposed length of the first fixing pin and / or the second removable pin in the axial direction of the handle, or at least the entire protruding and exposed length in the axial direction of a hollow tube without a closed end covering at least the entire protruding and exposed length of the first fixing pin.

[0030] According to some embodiments, in the tool, the first fixed pin is positioned with its longitudinal axis parallel to the longitudinal axis of the tool. According to some embodiments, in the tool, the second removable pin is positioned with its longitudinal axis parallel to the longitudinal axis of the tool when attached to the tool handle. In some embodiments, in the tool, the first fixed pin and the second removable pin are located at opposite ends of the tool handle. Thus, an advantage is that the pins are easy to keep track of and make the tool more compact and more flexible because there is no need for separate or additional storage or tracking of loose pins for replacement.

[0031] Other advantages of such a tool are that the hearing device and the tool are separate and easy to use, since the tool has a "built-in" removable locking pin which eliminates or at least reduces the risk of undoing such a small locking pin that has come loose before replacing an existing locking pin, and the tool is a single tool that can be used for two functions, namely removing the cover from the hearing device housing for cleaning and / or replacing the cover / filter and assembling the cover to the hearing device housing by providing two "built-in" pins (a fixed pin which is adapted to push out an existing / first locking pin in the hearing device at one end of the tool, and a second or further or additional removable locking pin which is adapted to be pushed by the other end of the tool into the same position in the hearing device as the first locking pin to replace it).

[0032] In another aspect, one or more of the above objects are achieved by a system.

[0033] The present invention relates to different aspects, including the systems described above and below, including corresponding hearing devices, binaural hearing devices, larger and / or smaller hearing devices, more advanced or less advanced (e.g. with more or fewer functions) hearing devices, systems, methods, devices, uses and / or product devices for helping people with hearing loss and / or any other devices configured to be used and / or in conjunction with hearing devices, such as tools and / or similar tools, each producing one or more of the benefits and advantages described in conjunction with the third mentioned aspect, and each having one or more embodiments corresponding to the embodiments described in conjunction with the third mentioned aspect and / or disclosed in the appended claims.

[0034] An advantage of a system comprising such a hearing device and a tool is that they are easy to use together by having an accessible tool handle that is easy to hold / grip and align with the hearing device.

[0035] According to the present invention, at least one object is achieved by a system, comprising a hearing device according to the above and / or below, and a tool for replacing a cover and / or a seal of a hearing device according to the above and / or below, wherein the tool comprises a handle with a first fixing pin for pushing out a locking pin that detachably cooperates with the cover and the hearing device housing, wherein the handle further comprises a second detachable pin, which is configured to replace the locking pin so as to detachably cooperate with the cover and the hearing device housing.

[0036] According to some embodiments, in the system, the second removable pin is attached to the handle by a second friction force. According to some embodiments, in the system, the second friction force is less than the first friction force. In some embodiments, in the system, the second friction force is greater than the gravity acting on the locking pin. According to some embodiments, in the system, the handle of the tool includes a retainer / bushing for the second removable pin. According to some embodiments, in the system, the retainer / bushing is made of plastic and / or rubber.

[0037] Another advantage of such a hearing device is that it is easy to clean, for example by directly placing it in water and / or other liquids for cleaning, without having to worry about any liquid leaking into the electronics of the hearing device. A further advantage of such a hearing device is that it can be worn in the shower and / or even in a bath / swimming and / or even during any rainstorm without risking water leaking into the electronics of the hearing device and endangering its functionality. A further advantage of such a hearing device is that the hearing device and the tool are easy to use together by having an accessible tool handle that is easy to hold / grip. A further advantage provided by such a hearing device and / or a system comprising such a hearing device and a separate tool is that the hearing device and the separate tool are easy to use, since the tool has a "built-in" removable locking pin, eliminating or at least reducing the risk of such a small locking pin coming loose before replacing an existing locking pin already in the hearing device. An advantage is that such a tool eliminates the need for two separate tools, i.e. a separate tool for removing the cover and / or the first locking pin and a second tool comprising the second removable pin and adapted to removably attach the second removable pin instead of the first removable locking pin are not necessary.

[0038] Another advantage with such a hearing device and / or a system comprising such a hearing device and a separate tool is that the same separate tool can be used for both functions, namely for removing the cover from the hearing device housing for cleaning and / or replacing the cover / filter and for assembling the cover to the hearing device housing by providing two "built-in" pins (one fixed pin adapted to be pushed out of an existing / first locking pin in the hearing device, and one second or further or additional removable locking pin adapted to be pushed into the hearing device at the same position as the first locking pin to replace it). This is a simplified and more stable / safe way for the user to replace the cover of a hearing device and / or its filter and / or its seal using both hands (one hand holding the hearing device and the other hand holding / moving the tool as required).

[0039] Other objects and features of the present invention will become apparent from the description of the following aspects / embodiments / implementations. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Each microphone 110 acts as an input transducer, and the function of the hearing device 10 will be briefly described here, as its function is common knowledge to the skilled person. Each microphone 110 receives sound through the audio channel 120 and the filter 210, and outputs an analog audio signal based on the acoustic sound signal arriving at the microphone when the hearing device 10 is in operation. The analog-to-digital converter converts the analog audio signal into a corresponding digital audio signal for digital signal processing in the hearing circuit, such as a hearing loss processor configured to compensate for the hearing loss of the user of the hearing device. Preferably, the hearing loss processor includes a dynamic range compressor known in the art to compensate for the frequency-dependent loss of the user's dynamic range, generally referred to in the art as recruitment. In this way, the hearing device 10 can be configured to restore loudness so that the loudness of the hearing loss compensation signal perceived by the user wearing the hearing device 10 substantially matches the loudness of the acoustic sound signal arriving at the microphone 110, as would be perceived by a listener with normal hearing. Therefore, the hearing loss processor outputs a digital hearing loss compensation audio signal. The digital-to-analog converter then converts the digital hearing loss compensation audio signal into a corresponding analog hearing loss compensation audio signal. The output transducer in the form of a receiver converts the simulated hearing loss compensation audio signal into a corresponding acoustic signal for transmission to the user's eardrum via a speaker or the like, thereby allowing the user to hear the sound that originally arrived at the microphone, compensating for the user's personal hearing loss. The hearing loss processor is operatively coupled to the control unit and / or main unit and / or knob 300 of the hearing device 10 in a manner known to the skilled person, so this function of the hearing device will not be further explained here.
