The invention relates to a hearing device, in particular a hearing aid. Furthermore, the invention relates to a kit for such a hearing device.
The term “hearing device” here and below in particular includes devices that are used to aid people who have impaired hearing abilities (hearing devices for this purpose are usually referred to as hearing aids), devices that are used for the purpose of tinnitus therapy (so-called tinnitus maskers) or devices for (tele-) communication (by way of example as a “headset”). In particular, hearing aids typically contain at least one microphone for ascertaining noises in the area surrounding a wearer of a hearing device. Furthermore, hearing aids usually contain a signal processing unit that is also referred to as a signal processor by which the ascertained noises are filtered, in part amplified and/or damped, and also where appropriate otherwise adjusted to the hearing impairment of the wearer of the hearing device. The noises that are processed in this manner are output to the ear of the wearer of the hearing device by a loudspeaker that is also referred to as an “earpiece”. As an alternative to the loudspeaker, devices for mechanically or electrically stimulating the hearing of the wearer of the hearing device (by way of example a cochlear implant) may be used.
Typically, non-rechargeable batteries, in particular “button cell” batteries, preferably in a zinc-air configuration are used to supply energy to the above described (electronic) components of a hearing device. Alternatively, in particular in expensive hearing devices, rechargeable energy sources (also referred to as rechargeable batteries) are also used.
The object of the invention is to simplify the production of hearing devices having different energy supply systems.
The hearing device in accordance with the invention contains an electronic frame for holding electronic components (such as for example at least one microphone, a loudspeaker and also a signal processor for processing the noises that are ascertained by the at least one microphone). Furthermore, the hearing device contains a first resilient contact and a second resilient contact. Both the first as well as the second resilient contact are in this case fastened to the electronic frame and preferably electrically connected to at least one of the electronic components. In this case, the two resilient contacts are configured with and provided with contact surfaces of a double-pole battery, the contact surfaces being in particular at a different electrical potential, so as to reversibly electrically contact at least one of the electronic components. Furthermore, the hearing device contains a “rechargeable battery module”, in other words a unit that contains a rechargeable battery and also an electronic convertor system. In this case, the electronic convertor system is used in particular so as to adjust the battery voltage value, which is provided by the rechargeable battery, to an operating voltage value that is required to operate the electronic components. In the intended assembled state of the hearing device, the rechargeable battery module is connected in an articulated manner to the electronic frame so as to be able to move and the rechargeable battery contains in addition connecting contacts that correspond to the two resilient contacts.
It is preferred that the rechargeable battery module also contains an electronic charging system for controlling a charging procedure of the rechargeable battery. It is preferred that the electronic charging system in this case also contains an antenna (by way of example an induction coil) for wireless charging of the rechargeable battery.
The double-pole battery is preferably a button cell (also known as: button battery) that in particular is embodied as a non-rechargeable battery (also referred to as a primary cell) in the form of a zinc-air battery. Alternatively, in this case the double-pole battery may also be a rechargeable battery (also referred to as a secondary cell or rechargeable battery) of the same design.
The electronic frame is preferably formed by a (in particular three-dimensional) circuit board or contains such a circuit board or a planar circuit board. In the latter case, the two resilient contacts are preferably fastened to the circuit board and are consequently fastened indirectly to the electronic frame.
The two resilient contacts are held preferably on a (common) contact carrier so as to simplify the assembly procedure on the electronic frame. This contact carrier is fastened to the electronic frame and is preferably electrically connected to at least one of the electronic components.
The fundamental idea of the invention is to be able to adapt a hearing device that is configured so as to use a predetermined energy source, specifically either a rechargeable battery module or a button cell, in particular during production in a simple manner so as to use another energy source, in other words the button cell or the rechargeable battery module. As a consequence, in particular the assembly outlay and in particular inventory-keeping costs for the respective components of hearing device models that are configured for different energy sources are reduced. By means of the above-described embodiment of the hearing device, in particular by means of the rechargeable battery module that is configured so as to contact the two resilient contacts that are provided for a conventional “hearing device battery” (button cell), it is advantageously possible in a particularly simple manner during the production of the hearing device depending upon the requirement to fit the hearing device for operation using a button cell or using a rechargeable battery, in particular using the rechargeable battery module. In particular, it is particularly advantageous that a particularly high proportion of common parts is provided by the embodiment in accordance with the invention for producing hearing devices having different energy sources with the result that inventory-keeping costs for storing a plurality of different components and assemblies may be reduced. Furthermore, assembly procedures may be simplified, in particular automated in a simpler manner, since only one small variation of components exists.
In one expedient embodiment, the rechargeable battery module contains three connecting contacts that are referred to below as first, second and third connecting contact. The first connecting contact and the second connecting contact are spaced with respect to one another in this embodiment in such a manner that these two connecting contacts are contacted in the intended contacting state of the rechargeable battery module, in particular simultaneously, by the first resilient contact. In other words, the first and the second connecting contact are short circuited by means of the first resilient contact in the intended contacting state. In this case, the third connecting contact is accordingly contacted using the second resilient contact.
The intended contacting state between the rechargeable battery module and the two resilient contacts of the contact carrier is produced in accordance with the above-mentioned embodiment in particular by moving the rechargeable battery module in the direction of the electronic frame, in particular in the direction of the contact carrier that carries the two resilient contacts. As a consequence, it is possible to switch on and switch off the hearing device by contacting the rechargeable battery module using the two resilient contacts or by removing the rechargeable battery module from these resilient contacts, comparable to inserting (by way of example swiveling or sliding) a button cell into the hearing device.
In one preferred embodiment, the second connecting contact of the rechargeable battery module is embodied in this case as a so-called control contact. This control contact is used in particular for the purpose of transferring the rechargeable battery module, preferably its electronic convertor system, reversibly into an active state or operating state (in other words switching on or switching off). The rechargeable battery module is activated in this case in particular by the above-described interconnection (“short circuit”) of the first connecting contact to the control contact. Consequently, in an advantageous manner it is also rendered possible that as the rechargeable battery module is removed from the two resilient contacts not only the hearing device, specifically its electronic components, are “switched off” but rather (in particular owing to removing the short circuit of the first connecting contact to the control contact) the electronic convertor system that is integrated into the rechargeable battery module is also switched off or at least transferred into a type of “stand by” mode or “sleep” mode. As a consequence, in particular it is rendered possible that even in the case of a switched off hearing device the electronic convertor system of the rechargeable battery module does not consume energy or only consumes energy to an insignificant extent.
In a further expedient embodiment, the two resilient contacts of the contact carrier preferably contain contact sites (in other words contact surfaces) that stand perpendicular with respect to one another. The two resilient contacts are therefore preferably configured for the purpose of contacting the button cell on one side on a planar face (end face) and on the other side on the peripheral surface (that is at another electrical potential). It is advantageously rendered possible by this embodiment of the resilient contacts when using the same resilient contacts to also be able to insert button cells that are of different thicknesses.
In order to produce a simple contacting arrangement of the rechargeable battery module using the resilient contacts of the above-mentioned embodiment, in one expedient embodiment the first connecting contact and the second connecting contact (or the control contact) contain respectively an allocated contact site, in particular a surface and in the intended contacting state the corresponding resilient contact of the contact carrier lies against said surface. These contact sites of the first and the second connecting contact (the control contact) lie in this case approximately in a common plane, in particular on a planar surface of the rechargeable battery module. The third connecting contact is in this case oriented in its allocated contact site transversely and in particular in the thickness direction of the rechargeable battery module offset with respect to the contact sites of the first and second connecting contact. By way of example, the rechargeable battery module contains an approximately cylindrical basic structure, wherein the contact sites of the first and second connecting contact are arranged on an end face and the contact site of the third connecting contact is arranged on the “outer surface” (in other words on a peripheral surface) of the rechargeable battery module.
In one preferred embodiment, the rechargeable battery module is connected in an articulated manner to the electronic frame or to a housing of the hearing device so as to be able to move, in other words by way of example may be displaced or in particular may be pivoted in the manner of a battery compartment door. It is particularly preferred that the rechargeable battery module in this case may be adjusted between an “operating position”, in which the rechargeable battery module is contacted in the intended manner using the resilient contacts, and an “off position” in which the connecting contacts of the rechargeable battery module are removed from the resilient contacts and consequently the energy supply to the electronic components of the hearing device is interrupted. It is preferred in this case that in the off position the electronic convertor system of the rechargeable battery module is also deactivated (in other words is switched off or in the sleep mode).
The kit in accordance with the invention for a hearing device contains the hearing device of the above-described type. In other words, the kit contains the hearing device that in turn contains the electronic frame and also the two resilient contacts (where appropriate that are held on the contact carrier) of the above-mentioned type and also the above-described rechargeable battery module. Moreover, the kit also contains a battery compartment door for reversibly holding the button cell. In this case, this battery compartment door may be connected in an articulated manner in particular so as to be able to pivot on the electronic frame or on the housing of the hearing device (in other words is connected in an articulated manner in the intended assembled state) in such a manner that as the battery compartment door is pivoted into a closed position the contact surfaces of the button cell (that is inserted into the battery compartment door in the intended manner) are contacted using the two resilient contacts. The hearing device of the kit in accordance with the invention may consequently if necessary advantageously be selectively fitted with the above-described battery compartment door or the above-described rechargeable battery module, in particular depending upon the energy source that is to be used. This fitting procedure is already performed by way of example during the production of the hearing device, but this fitting may also preferably be performed by a hearing device acoustician or a comparable person skilled in the art at the point of sale or as the hearing device is adjusted to suit a wearer of the hearing device depending upon their request.
The hearing device according to an alternative variant of the invention likewise contains an electronic frame for holding electronic components. This electronic frame and also the electronic components correspond in this case essentially to the above-described type. Furthermore, the hearing device contains three resilient contacts (that are referred to below as first, second and third resilient contact) that are fastened (directly or by way of example indirectly by means of a contact carrier) to the electronic frame and are preferably electrically connected to at least one of the electronic components. These three resilient contacts are used—in accordance with this alternative embodiment in accordance with the invention—so as to electrically contact at least one of the electronic components with a rechargeable battery module that contains a rechargeable battery. Such a rechargeable battery module in this case contains a first connecting contact, a second connecting contact (referred to as the control contact) and a third connecting contact, which lies opposite the first connecting contact at a different (electrical) potential so as to contact the three resilient contacts. Moreover, the hearing device contains a battery carrier for holding a button cell so that it may move in relation to the contact carrier. This embodiment of the hearing device in accordance with the invention is therefore fundamentally initially configured for use with the rechargeable battery module as an energy source. However, in order by way of example during production of the hearing device to be able to configure the hearing device in a simple manner for operation with a hearing device battery (in particular the above-mentioned) button cell, the hearing device contains the above-described battery carrier. The above-described inventive idea—to also be able to use another energy source for a hearing device that is configured for operation with a specific energy source—is achieved by means of this embodiment in a manner that is similar but inverted with respect to the above-mentioned embodiments.
In addition to the rechargeable battery, the rechargeable battery module also contains the electronic convertor system similar to the above-mentioned embodiments. The rechargeable battery module preferably also contains the electronic charging system and also in particular the antenna for wireless charging of the rechargeable battery.
The three resilient contacts are arranged in a preferred embodiment on the above-mentioned contact carrier that is embodied separately from the electronic frame and is fastened to the electronic frame (in other words is configured in particular for the purpose of being fastened to the electronic frame when assembling the hearing device).
In one expedient embodiment, the hearing device is configured for the purpose of transmitting a control signal for activating or deactivating the electronic convertor system of the rechargeable battery module by the resilient contact (in particular the third) that is allocated to the second connecting contact (the control contact) of the rechargeable battery module.
In a further preferred embodiment, in the intended contacting state between the three resilient contacts and the double-pole battery (in particular the button cell) the (second and third) resilient contacts that are allocated respectively to the second connecting contact (in other words the control contact) and the third connecting contact of the rechargeable battery module lie respectively against a contact surface, the contact surface forming a pole of the button cell, in particular on an outer surface of the button cell. The resilient contact that is allocated to the first connecting contact of the rechargeable battery module lies in this state in particular on the further contact surface of the double-pole battery (specifically the button cell), in particular on an end face of the double-pole battery, the contact surface forming the corresponding other pole. In other words, in this embodiment when using a double-pole (in particular non-rechargeable) battery, specifically the button cell, the (third) resilient contact that is used to transmit the control signal to the rechargeable battery module also lies against the button cell and consequently contacts the button cell. This contacting arrangement of the resilient contact that is used to transmit the control signal and contains the second contact surface of the button cell (in addition to the second resilient contact) has turned out surprisingly to be non-critical with regard to malfunctions, a short circuit or the like. As a consequence, it is advantageously possible to reduce the constructive outlay for adapting the hearing device that is configured for operation with the rechargeable battery module for use with a battery.
It is preferred that within the scope of the above-described embodiment the second and the third resilient contact are embodied in such a manner that their contact sites (or: contact surfaces) lie in a common surface while the contact site of the first resilient contact lies accordingly in a surface that stands perpendicular with respect to the first resilient contact (in order to be able to bring said contact site into contact with the end face of the button cell).
In one expedient embodiment, the battery carrier is embodied in the shape of a battery compartment door. This is preferably held on the electronic frame or on the housing of the hearing device so as to be able to pivot. In order to “switch on” or activate the hearing device, the battery compartment door that carries the button cell in the intended operating state is therefore preferably moved (pivoted) into a closed position (in particular in the direction of the electronic frame) in such a manner that the first resilient contact contacts a contact surface of the button cell and the second and third resilient contacts simultaneously contact the other contact surface of the button cell. In order to switch off or deactivate the hearing device, the battery compartment door is consequently moved to such an extent that the respective contacting arrangements between the first, second and third resilient contacts and the respective contact surfaces are separated. In this case, as a consequence, the control signal that is transmitted via the third resilient contact so as to activate or deactivate the rechargeable battery module may also not be transmitted.
In an alternative embodiment that is also perceived as a separate invention, the battery carrier of the hearing device contains two contact springs for reversibly electrically contacting the respective contact surfaces of the button cell (said contact surfaces in particular being at a different potential) using the corresponding (in particular in relation to the electrical potential) resilient contacts. The two contact springs are consequently preferably used to provide the electrical contact between the contact surfaces of the button cell and the resilient contacts that are arranged on the electronic frame. The battery carrier in this case forms a type of interface or adaptor between a preferably conventional “hearing device battery” (in other words the button cell) and the resilient contacts of the hearing device, the resilient contacts being configured so as to contact the rechargeable battery module. The resilient contacts in this case lie in a common (in particular planar) plane so as to contact the rechargeable battery module in a simple manner, preferably using the contact surfaces of the resilient contacts.
Within the scope of this alternative embodiment, the battery carrier is also expediently configured for the purpose of preventing a contacting arrangement between the (third) resilient contact and the button cell, the third resilient contact being used to transmit the control signal or control command to the control contact. In particular, in the intended contacting state of the button cell, the third resilient contact is insulated by way of example by a wall of the battery carrier with respect to the button cell.
In a preferred embodiment, the battery carrier is also embodied in this case as a battery compartment door and the two contact springs are however integrated into the battery compartment door. It is preferred that the battery carrier in this case is connected in an articulated manner so as to be able to pivot on the electronic frame or on a housing of the hearing device.
In one expedient embodiment, the contact springs of the battery carrier are embodied according to a type of leaf spring. In particular, the two contact springs are arranged in the battery carrier in such a manner that one of the two contact springs touches a planar face of the button cell (that is preferably embodied as a button battery or button cell) and the other contact spring touches an outer surface that is at a different potential with respect to the above-mentioned planar face.
In a particularly expedient embodiment, in particular the contact spring of the battery carrier contains a helicoidal section, the contact spring touching the planar face of the button cell. This helicoidal section is embodied in this case in such a manner that it may compress in the thickness direction of the button cell. As a consequence, it is advantageously rendered possible to also use button cells that are of different thicknesses with the battery carrier, in particular the button cells may be inserted with their planar face (also referred to as end face) that lies opposite the helicoidal section in a flush manner with respect to the battery carrier.
In a further expedient embodiment, the battery carrier contains a base body and the contact springs are arranged on the base body and the base body (preferably in the intended state of use of the battery carrier) is connected in an immovable manner to the electronic frame, in particular fixedly (in other words preferably rigidly) connected to and contacted by the electronic frame, in particular the contact carrier. In this case, the battery carrier contains preferably in addition a flap that may pivot and is embodied in particular according to a type of a battery compartment door and in the intended inserted state of the button cell is reversibly held and the flap may reversibly pivot on to the contact springs that are arranged on the base body. In other words, the battery carrier in this embodiment contains a “dedicated” battery compartment door by which the inserted button cell may be contacted using the contact springs or removed from the contact springs so as to activate and deactivate the hearing device or the electronic components of the hearing device.
The kit in accordance with the invention contains the above-described hearing device that is configured by the three resilient contacts that are arranged on the electronic frame (optionally by means of the contact carrier) so as to contact the rechargeable battery module. Moreover, this kit contains the rechargeable battery module of the above-described type. In other words, the kit contains both the above-described battery carrier and also the rechargeable battery module that in particular contains the rechargeable battery, the electronic convertor system, the first connecting contact, the control contact and also the third connecting contact that correspond respectively to the resilient contacts (of the contact carrier). This rechargeable battery module in this case is preferably configured so as to be fixedly (preferably rigidly, in other words in particular immovably) installed in a housing of the hearing device. In this case, therefore preferably selectively either the rechargeable battery is fixedly mounted in the housing or is inserted into the battery compartment door that may pivot.
It is preferred that in the case of this rechargeable battery module (in particular for the case that the second and third resilient contact contact the button cell on the same contact surface) the contact sites that are allocated to the second and third connecting contact respectively lie in a common surface, in particular in an outer surface of the rechargeable battery module that is preferably embodied as approximately cylindrical. The contact site of the first connecting contact in this case preferably lies transversely with respect to the contact sites of the second and third connecting contact, in particular on an end face of the rechargeable battery module, the end face standing approximately at a right angle with respect to the outer surface.

In this case, the first contact spring 64 is arranged in such a manner that it contacts the first contact surface 16 of the button cell 14 in the intended inserted state. The second contact spring 66 is positioned in the battery compartment door 60 in such a manner that the contact spring touches the second contact surface 18, in other words the outer surface of the button cell 14. In this case, the two contact springs 64 and 66 lie respectively in a recess 70 and 72 of a side wall of the battery compartment door 60 open toward the outer face with the result that as the battery compartment door 60 is pivoted inward in the direction of the electronic frame 1, the resilient contacts 50 and 52 of the electronic frame 1 that are allocated to the respective potential of the two contact surfaces 16 and 18 of the button cell 14 come into electrical contact with the open section of the contact springs 64 or 66 that lies in the respective recess 70 or 72. The resilient contact 51 that corresponds to the control contact 34 of the rechargeable battery module 30 is prevented in this case from contacting the second contact surface 18 of the button cell 14 by (the side wall) of the battery compartment door 60.
