Description

The invention relates to a hearing device with a microphone unit and a loudspeaker unit, a connector and the use of a connector for connecting a microphone unit and a loudspeaker unit of a hearing device.

The hearing aid of this type is used in particular to help people with hearing impairments to hear better. In known hearing aids, the microphone unit and the loudspeaker unit are usually connected to one another by means of a locking pin running in the radial direction of the components to be connected and penetrating several components, or by means of a bayonet catch. This requires an increased degree of manufacturing accuracy for the secure connection of the microphone unit and the loudspeaker unit.

To avoid this disadvantage, the present invention aims to provide an improved hearing aid with a microphone unit and a loudspeaker unit, an improved connector and the use of an improved connector for connecting a microphone unit and a loudspeaker unit of a hearing aid, with in particular a secure connection of the Microphone unit and the speaker unit is realized with reduced manufacturing costs.

The object is achieved by the subject matter of the respective independent patent claim. The respective dependent patent claims relate to preferred developments of the subject matter of the present invention.

One aspect relates to a hearing aid to be worn on the ear with a microphone unit, a loudspeaker unit and a connecting element, the microphone unit having a Housing having at least one microphone and the housing is worn on the ear in use. The loudspeaker unit has a cable and a loudspeaker connected to a first end of the cable, which loudspeaker is inserted in an ear canal in use. The cable is detachably connected to the housing by means of a connector, the connector being arranged at a second end of the cable opposite the loudspeaker. In this case, a groove for engaging with the connecting element is formed on the connector and extends at least partially in the circumferential direction of the connector, the connecting element being engaged with the groove in an assembly position of the microphone unit and the loudspeaker unit in order to fasten the connector to the housing of the to secure the microphone unit.

An advantage of the present invention is a simplified manufacture of the hearing aid while ensuring a secure connection of the microphone unit and the loudspeaker unit of the hearing aid, in particular secured by means of the connecting element against relative movement in the axial direction of the connector between the microphone unit and the loudspeaker unit in its installed position. In particular, the groove formed on the connector is easy to produce and, together with the connecting element of the hearing aid, ensures the secure connection of the microphone unit and the loudspeaker unit.

Another advantage of the present invention is quick and easy connection/disconnection of the microphone unit and the speaker unit by inserting/removing the connector.

A connector for the detachable connection of a microphone unit and a loudspeaker unit can be used in particular for mechanical and/or electrical connection. The connector can thus have components for mechanical connection, components for electrical connection and/or components for combined mechanical and electrical connection. An external shape of the connector can be adapted to a respective requirement and/or geometry of the units to be connected, for example the connector can have an approximately cylindrical external shape.

A cable of a loudspeaker unit usually runs over the ear when the hearing device is worn. In order to support the wearing of the hearing device on the ear, the cable can be stiff or rigid, in particular preformed to fit an ear. Alternatively, the cable can be flexible.

An axial direction or axial direction can be a direction in an extension of a length of a component. In the case of a connector designed, for example, in the form of a cylinder, the axial direction is aligned approximately parallel to a surface line or the longitudinal axis of the connector.

A radial direction or radial direction may be oriented perpendicular to the axial direction. For example, in the case of a cylindrically shaped connector, the radial direction is aligned to coincide with the radius of the cylindrically shaped connector.

A secant direction may be oriented perpendicular to the axial direction in the direction of a secant. In the case of a connector designed, for example, in the shape of a cylinder, which has a circular cross-sectional area when cut transversely to the axial direction, the respective secant direction runs in the direction of a chord of a circle.

Accordingly, a circumferential direction can be a direction in an extension of the circumference of the connector, which is configured, for example, in a cylindrical shape.

The terms "outside" or "inside" and the like used here mean in the context of the present invention that a center point, particularly an idealized or imagined center point, is an innermost point. Thus, a point or area that is designated as being more outward than another point or area is radially farther from the center point than the other point or area that is more inward. Thus, a point or region that is designated as being more inward than another point or region is radially closer to the center point than the other point or region that is more outward. For example, an outer Surface of the connector described in the mounting position of the microphone unit and the speaker unit arranged within the housing of the microphone unit. The interior of the housing is bounded by an outer wall of the housing, with anything further radially outward than the outer wall of the housing being outside of the housing.

In the context of the present invention, the terms “above” or “above” and the like used below mean a direction and/or a position of an element in relation to another element against the direction of gravity, ie in the positive z direction. In the context of the present invention, the terms “below” or “below” and the like used below mean a direction and/or a position of one element in relation to another element in the direction of gravity.

The connector can have at least one bracket, which can be formed on the outside of the connector. In other words, the at least one holder can be arranged on an outer surface—that is, on an outer surface—of the connector.

In particular, the connector can be releasably locked to the housing of the microphone unit by means of the holder in the mounting position of the microphone unit and the loudspeaker unit.

Advantageously, with the above configuration, the mount on the connector is easily accessible for easy and effective locking of the speaker unit, particularly the connector, to the housing of the microphone unit.

A further aspect relates to a hearing device to be worn on the ear with a microphone unit and a loudspeaker unit, the microphone unit having a housing with at least one microphone and the housing being worn on the ear during use. The loudspeaker unit has a cable and a loudspeaker connected to a first end of the cable, which loudspeaker is inserted in an ear canal in use.

The cable is detachably connected to the housing by means of a connector, the connector being arranged at a second end of the cable opposite the loudspeaker. In this case, the connector is releasably locked to the housing of the microphone unit in a mounting position of the microphone unit and the loudspeaker unit by means of at least one holder which is formed on the outside of the connector.

To put it in other words, the at least one holder can be arranged on an outer surface - that is, on an outer surface - of the connector, in particular in an unconnected state of the microphone unit and the loudspeaker unit. In this case, the outer surface of the connector is arranged inside the housing of the microphone unit in the mounting position of the microphone unit and the loudspeaker unit.

An advantage of the present invention is a simplified manufacture of the hearing aid while ensuring a secure releasable locking of the connector to the housing of the microphone unit in a mounting position of the microphone unit and the loudspeaker unit. In particular, the at least one holder formed on the connector is easy to produce and, together with the housing of the microphone unit, ensures that the connector is securely and releasably locked to the housing.

The bracket can extend at least partially in the radial direction of the connector. In other words, the at least one holder can be designed to protrude outwards from an outer surface—that is, from an outer surface—of the connector in the radial direction of the connector.

The above configuration further contributes to the easy access of the retainer on the connector for easy and effective locking of the speaker unit, particularly the connector, to the housing of the microphone unit.

Advantageously, the hearing aid may have a connecting element, a groove for engaging the connecting element being formed on the connector can be and can extend at least partially in the circumferential direction of the connector. In this case, the connecting element can be engaged with the groove in the mounting position of the microphone unit and the loudspeaker unit in order to secure the connector on the housing of the microphone unit.

By means of the connecting element, a positive and/or frictional connection can be formed between the microphone unit and the loudspeaker unit in their mounting position.

In particular, in the assembly position of the microphone unit and the loudspeaker unit, a positive and/or frictional connection can be formed between the housing of the microphone unit and the groove of the connector by means of the connecting element.

To bring about the positive connection, the connecting element can engage behind the connector.

Advantageously, with the above configuration, precise and easy connection/disconnection of the microphone unit and the speaker unit can be ensured quickly and easily by inserting/removing the connector.
Advantageously, the connecting element can be designed to be elastically deformable.

Thus, easy and efficient engagement of the connecting member with the groove can be ensured.

For example, the connecting element can be designed as a spring ring—like a locking ring, a circlip or a grooved ring—or as a spring clip—like a spring clip or a permanent cotter pin, in particular made of metal or plastic.

Advantageously, the above configuration can further contribute to a quick and easy connection/disconnection of the microphone unit and the loudspeaker unit by inserting/removing the connecting element, in particular by means of easy-to-procure, inexpensive and standardized standard parts.

The connecting element can be designed separately and/or arranged captively on the housing of the microphone unit. For captive fastening, the connecting element can be fastened to the housing, for example, by means of a cord, wire or chain, with the freedom of movement required for handling the connecting element being taken into account in the length of the respective fastening means.

As an alternative to this, the connecting element can be designed in one piece with the housing of the microphone unit. For example, the connecting element can be in the form of a spring clip section cast onto a plastic housing or can be produced during manufacture of the housing using an injection molding process. As an alternative to this, the connecting element--regardless of the respective material--can be glued to the housing, encapsulated therewith or connected to it in some other way so as not to be detachable.

A corresponding opening can be formed on the housing of the microphone unit, through which the connecting element can engage in the mounting position of the microphone unit and the loudspeaker unit in the groove of the connector, whereby a form fit of the microphone unit with the loudspeaker unit can thus be produced, one, in particular prevents unintentional separation of the microphone unit from the speaker unit.

In particular, the groove can be formed on the outside of the connector. In other words, the groove can be arranged on an outer surface - that is, on an outer surface - of the connector.

Thus, the groove on the connector is readily accessible for easy and efficient engagement of the connector with the groove.

For example, a groove may be formed on opposite sides of the connector in the radial direction of the connector. In other words, a total of two separate grooves can be formed on opposite sides of the connector in the radial direction of the connector.

In this case, the groove can be formed at least partially in the circumferential direction of the connector.

Alternatively or additionally, the groove can be formed at least partially in the secant direction of the connector.

Furthermore, the groove can at least partially have a constant depth, ie a constant extension in the radial direction of the connector.

Alternatively or additionally, the groove can at least partially have a variable depth as seen over its extent in the circumferential or secant direction of the connector, with the maximum of the depth of the groove occurring approximately in the middle of its extent in the circumferential or secant direction of the connector.

Advantageously, at least one holder can be formed on opposite sides of the connector in the radial direction of the connector.

Thus, the housing of the microphone unit can be locked to the connector smoothly and securely. Furthermore, with the above configuration, a simple and effective guidance of the housing on the holders can be achieved, in particular by means of housing receptacles described below. Also A reliable electrical contact, which is described in more detail below, can be achieved with the above configuration by simply plugging the loudspeaker unit into the microphone unit.

In particular, the holder can be cylindrical.

A longitudinal axis of the holder can be aligned at least partially in the radial direction of the connector. In other words, the holder can be designed to protrude outwards from the connector in the radial direction of the connector.

Thus, the mount on the connector is easily accessible for easy and effective locking of the loudspeaker unit, particularly the connector, to the housing of the microphone unit.

The at least one holder can be formed on a base plate, which can be arranged on a first end section of the connector, in particular on a contacting section described below. The base plate can be formed with mutually parallel guide surfaces, wherein the guide surfaces can be aligned in the axial direction of the connector. The guide surfaces can run toward one another on an end section of the base plate, which faces the housing of the microphone unit in the mounting position of the microphone unit and the loudspeaker unit. For example, the guide surfaces can enclose an angle of approximately 90° at one end section.

With the above configuration, for efficiently and easily locking the housing of the microphone unit to the bracket, a guide for the receptacles described below can be effected on the housing to securely position the receptacles and the brackets relative to each other.

For example, the connector of the loudspeaker unit and the housing of the microphone unit can be brought together in such a way that the receptacles are positioned on the brackets for locking and by means of a pivoting movement of the connector, the connector can be locked to the housing. Alternatively or additionally, the housing may be locked to the connector by pivoting the housing.

Advantageously, the holder can interact with the connecting element in order to ensure both a releasable locking of the housing of the microphone unit on the connector and a securing of the connector on the housing of the microphone unit in the mounting position of the microphone unit and the loudspeaker unit.

In particular, the housing of the microphone unit can be releasably locked to the connector by means of a positive fit of the housing with the mount, which has at most one degree of freedom, namely a rotational degree of freedom of the housing around the mount. In this case, not only can a relative movement in the axial direction of the connector between the housing and the connector be prevented by means of the connecting element, which for example also acts in a form-fitting manner between the housing and the connector, the housing of the microphone unit can also be releasably locked to the Connectors are effected, which has no more degrees of freedom.

To bring about the positive connection, the connecting element can engage behind the connector. Furthermore, the respective receptacle can engage behind the associated holder to bring about the form fit.

Depending on the design of the holder, however, the housing of the microphone unit can also be locked on the connector without any degree of freedom. In this case, the locking of the housing of the microphone unit on the connector can be additionally secured by means of the connecting element.

For example, in the case of two cylindrical holders, one holder each on opposite sides in the radial direction of the connector of the connector is formed, the aforementioned locking of the housing of the microphone unit on the connector can be effected with exactly one rotational degree of freedom around the mounts. For this purpose, the housing can be designed with receptacles, for example hollow-cylindrical bushings, which are assigned to and adapted to the respective holders.

For this purpose, the housing can be designed to be elastically deformable in such a way that, in the mounting position of the microphone unit and the loudspeaker unit, it can be expanded in the radial direction of the connector to such an extent that the respective receptacle can be placed over the associated holder. After the end of the widening, the housing can then return to its original shape and the respective holder can thus be accommodated in the associated receptacle. In other words, the respective holder can be surrounded by the associated receptacle at least in the circumferential direction of the holder, in particular without play.

Alternatively, for example, with four cylindrical brackets, two of which are formed on opposite sides of the connector in the radial direction of the connector, the aforementioned locking of the housing of the microphone unit to the connector can be effected without a degree of freedom. In this case, the respective brackets can be formed on one side of the connector in the radial direction of the brackets or in the axial direction of the connector at a distance from one another.

In particular, when the housing of the microphone unit is locked to the connector, each individual holder can be accommodated in the respectively associated receptacle.

As an alternative or in addition to this, a plurality of holders can be accommodated in a common, assigned receptacle on the same side of the connector, viewed in the radial direction of the connector.

As a further alternative or in addition to this, holders formed on opposite sides of the connector in the radial direction of the connector can be accommodated in a common, assigned receptacle.

For example, holders formed on opposite sides of the connector in the radial direction of the connector can be accommodated in pairs or crosswise in a common, assigned receptacle.

Advantageously, with the above configuration, by means of two or four cylindrical brackets, effective guidance of the housing on the brackets for positioning the housing on the connector can be achieved for easy and effective locking of the speaker unit and the microphone unit in their mounting position. Compared to a guide on long guide surfaces, this guide can have a lower tendency to jam and/or tilt. A secure electrical contact, which is described in more detail below, can also be supported with the above configuration for simple and effective locking of the loudspeaker unit and the microphone unit in their mounting position.

In particular, the two holders can have different diameters from one another on the same side of the connector, viewed in the radial direction of the connector. Furthermore, the brackets that are respectively opposite to one another in the radial direction of the connector can have the same diameter.

For example, a fixture diameter/length ratio may be in the range of about 0.75 to about 1.25, or in the range of about 0.85 to about 1.15, or about 1. Thus, a holder that is relatively short in relation to its diameter can be achieved, which can enable effective locking with the housing of the microphone unit.

For this purpose, the housing can likewise be associated with the respective holders and adapted to the respective holders, for example hollow cylindrical sockets, be formed. As an alternative or in addition to this, the housing of the microphone unit can be designed with spring clips assigned to the respective holders, for example spring clips or permanent cotter pins.

Similar to the connection element described above, at least one of the receptacles can be arranged captively on the housing of the microphone unit.

As an alternative to this, at least one of the receptacles can be formed in one piece with the housing of the microphone unit. For example, the respective receptacle can be in the form of a receptacle section cast onto a plastic housing or can be produced during the production of the housing using an injection molding process. As an alternative to this, the connecting element--regardless of the respective material--can be glued to the housing, encapsulated therewith or connected to it in some other way so as not to be detachable.

A guide device can be formed on the housing of the microphone unit, which corresponds to the previously described guide surfaces of the base plate for the at least one mount, in order to ensure secure positioning of the respective receptacle on the associated mount. For example, the guide device can have mutually parallel guide surfaces within which the guide surfaces of the base plate can be accommodated. Advantageously, the guide surfaces of the guide device, like the guide surfaces of the base plate, can be aligned in the axial direction of the connector.

At least one contacting element for establishing an electrical contact between the microphone unit and the loudspeaker unit can advantageously be formed on the connector.

The at least one contacting element can be designed as an electrical contact element such as a spring contact, in particular a spring tongue, a—in particular spring-loaded—contact pin or the like.

Thus, in addition to the previously described mechanical locking and securing of the microphone unit and the loudspeaker unit, the connector can also be used to ensure an electrical connection between the microphone unit and the loudspeaker unit in their mounting position.

Alternatively or additionally, at least one contacting element can also be suitable for the mechanical connection between the microphone unit and the loudspeaker unit in their mounting position. For example, in the assembly position of the microphone unit and the loudspeaker unit, an end section of the at least one contacting element can be held in a corresponding receiving section on the housing of the microphone unit, in particular in a form-fitting manner, or latched thereto.

The at least one contacting element can thus contribute to the secure mechanical connection between the microphone unit and the loudspeaker unit in their mounting position.

For example, the at least one contacting element can be designed as a contact spring that protrudes beyond the connector, in particular in the axial direction of the connector.

In particular, the at least one contacting element can be arranged in a contacting section on a first end section of the connector. The at least one contacting element can be designed as a contact spring that protrudes beyond the contacting section in the axial direction of the contacting section. For example, the contacting elements can be designed to protrude beyond the contacting section in both axial directions of the contacting section.

The contact spring can be designed to be elastically deformable and can be made, for example, from an electrically conductive metal or an electrically conductive metal alloy.

Furthermore, the above-described at least one holder of the connector can be arranged on the contacting section.

A sealing element for sealing between the connector and the housing of the microphone unit can advantageously be arranged on the connector. In other words, in the mounting position of the microphone unit and the loudspeaker unit, a gap between the connector and the housing of the microphone unit can be sealed by means of a sealing element.

In particular, the sealing element can be arranged between the groove and a second end portion of the connector as seen in the axial direction of the connector, the cable exiting from the second end portion of the connector. In other words, seen in the axial direction of the connector, the sealing element can be arranged further outwards in relation to the housing than the groove and/or the at least one contacting element in the mounting position of the microphone unit and the loudspeaker unit.

The interior of the housing of the microphone unit can thus be effectively protected from environmental influences such as moisture and/or dust from the direction of the loudspeaker unit by means of the sealing element in the mounting position of the microphone unit and the loudspeaker unit.

For example, the sealing element can be designed as an O-ring, which can be accommodated or accommodated in a groove running around in the circumferential direction of the connector.

Advantageously, the sealing element designed as an O-ring can be easily replaced in the event of wear and/or a decreasing sealing effect.

As an alternative or in addition to this, the sealing element can be molded onto the connector, in particular running around in the circumferential direction of the connector, and in particular can contain an elastomer.

Advantageously, the sealing element formed in one piece with the connector in this way can be precisely adapted to a gap existing between the housing and the connector in the mounting position of the microphone unit and the loudspeaker unit, and thus an improved sealing effect can be achieved compared to a separately formed O-ring.

In particular, a stop for the housing of the microphone unit, which protrudes in the radial direction of the connector, can be formed on the second end section of the connector.

The stop can be formed at least partially in the circumferential direction of the connector.

By means of the stopper, the connector can be inserted into the housing to an appropriate extent in a mounting position of the microphone unit and the loudspeaker unit in order to effectively lock the housing with the holder and to effectively secure the connector to the housing.

A further aspect of the invention relates to a connector for connecting a microphone unit and a loudspeaker unit of a hearing aid, wherein a groove for engaging with a connecting element is formed on the connector and extends at least partially in the circumferential direction of the connector and wherein the connecting element in a mounting position of the Microphone unit and the speaker unit is engageable with the groove to secure the connector to a housing of the microphone unit.

The advantages of the connector for connecting a microphone unit and a loudspeaker unit of a hearing device result analogously from the above described hearing aid with the connector mentioned features and their advantages.

A further advantage of the present invention is a simplified manufacture of the groove formed on the connector, which together with the connecting element which can be brought into engagement therein, ensures the secure connection of the microphone unit and the loudspeaker unit, in particular against a relative movement in the axial direction of the connector between the microphone unit and the loudspeaker unit their mounting position.

The connecting element can be designed as a spring ring—such as a locking ring, a circlip or a grooved ring—or as a spring clip—such as a spring clip or a permanent cotter pin, in particular made of metal or plastic.

In particular, the groove can be formed on the outside of the connector. In other words, the groove can be arranged on an outer surface - that is, on an outer surface - of the connector.

Thus, the groove on the connector is readily accessible for easy and efficient engagement of the connector with the groove.

For example, a groove may be formed on opposite sides of the connector in the radial direction of the connector. In other words, a total of two separate grooves can be formed on opposite sides of the connector in the radial direction of the connector.

In this case, the groove can be formed at least partially in the circumferential direction of the connector.

Alternatively or additionally, the groove can be formed at least partially in the secant direction of the connector.

Furthermore, the groove can at least partially have a constant depth, ie a constant extent in the radial direction of the connector.

Alternatively or additionally, the groove can at least partially have a variable depth as seen over its extent in the circumferential or secant direction of the connector, with the maximum of the depth of the groove occurring approximately in the middle of its extent in the circumferential or secant direction of the connector.

Another aspect of the invention relates to a connector for connecting a microphone unit and a loudspeaker unit of a hearing aid, wherein at least one holder for releasably locking the connector to a housing of the microphone unit is formed on the outside of the connector and extends at least partially in the radial direction of the connector.

To put it in other words, the at least one holder can be arranged on an outer surface - that is, on an outer surface - of the connector.

The advantages of the connector for connecting a microphone unit and a loudspeaker unit of a hearing device result analogously from the features mentioned for the hearing device with the connector described above and their advantages.

A further advantage of the present invention is a simplified production of the holder formed on the connector which, together with the housing of the microphone unit which can be releasably locked therewith, ensures the secure connection of the connector to the microphone unit in the mounting position of the microphone unit and the loudspeaker unit.

Advantageously, at least one holder can be formed on opposite sides of the connector in the radial direction of the connector.

Thus, the housing of the microphone unit can be locked to the connector smoothly and securely.

In particular, the holder can be cylindrical.

A longitudinal axis of the holder can be aligned at least partially in the radial direction of the connector. In other words, the holder can be designed to protrude outwards from the connector in the radial direction of the connector.

Thus, the mount on the connector is easily accessible for easy and effective locking of the loudspeaker unit, particularly the connector, to the housing of the microphone unit.

The at least one holder can be formed on a base plate, which can be arranged on a first end section of the connector, in particular on a contacting section described below. The base plate can be formed with mutually parallel guide surfaces, wherein the guide surfaces can be aligned in the axial direction of the connector. The guide surfaces can run toward one another on an end section of the base plate, which faces the housing of the microphone unit in the mounting position of the microphone unit and the loudspeaker unit. For example, the guide surfaces can enclose an angle of approximately 90° at one end section.

With the above configuration, for efficiently and easily locking the housing of the microphone unit to the bracket, a guide for the receptacles described below can be effected on the housing to securely position the receptacles on the bracket.

Advantageously, the holder can interact with the connecting element in order to ensure both a releasable locking of the housing of the microphone unit on the connector and a securing of the connector on the housing of the microphone unit in the mounting position of the microphone unit and the loudspeaker unit.

For example, a total of two cylindrical holders can be formed on opposite sides of the connector in the radial direction of the connector.

As an alternative to this, a total of four cylindrical holders can be formed on the connector, with two being formed on opposite sides of the connector in the radial direction of the connector. In this case, the holders can be formed on one side of the connector in the radial direction of the holders or in the axial direction of the connector at a distance from one another.

Advantageously, with the above configuration, by means of two or four cylindrical brackets, effective guidance of the housing on the brackets for positioning the housing on the connector can be achieved for easy and effective locking of the speaker unit and the microphone unit in their mounting position. Compared to a guide on long guide surfaces, this guide can have a lower tendency to jam and/or tilt. A secure electrical contact, which is described in more detail below, can also be supported with the above configuration for simple and effective locking of the loudspeaker unit and the microphone unit in their mounting position.

In particular, the two holders can have different diameters from one another on the same side of the connector, viewed in the radial direction of the connector. Furthermore, the brackets that are respectively opposite to one another in the radial direction of the connector can have the same diameter.

For example, a fixture diameter/length ratio may be in the range of about 0.75 to about 1.25, or in the range of about 0.85 to about 1.15, or about 1. Thus, a holder that is relatively short in relation to its diameter can be achieved, which can enable effective locking with the housing of the microphone unit.

At least one contacting element for establishing an electrical contact between the microphone unit and the loudspeaker unit can advantageously be formed on the connector.

Thus, in addition to mechanically locking and securing the microphone unit and the loudspeaker unit, the connector can also be used to ensure an electrical connection between the microphone unit and the loudspeaker unit in their mounting position.

Alternatively or additionally, at least one contacting element can also be suitable for the mechanical connection between the microphone unit and the loudspeaker unit in their mounting position. For example, in the assembly position of the microphone unit and the loudspeaker unit, an end section of the at least one contacting element can be accommodated or latched in a corresponding receiving section on the housing of the microphone unit, in particular with a positive fit.

The at least one contacting element can thus contribute to the secure mechanical connection between the microphone unit and the loudspeaker unit in their mounting position.

For example, the at least one contacting element can be designed as a contact spring that protrudes beyond the connector, in particular in the axial direction of the connector.

In particular, the at least one contacting element can be arranged in a contacting section on a first end section of the connector. The at least one contacting element can be designed as a contact spring that protrudes beyond the contacting section in the axial direction of the contacting section. For example, the contacting elements can be designed to protrude beyond the contacting section in both axial directions of the contacting section.

The contact spring can be designed to be elastically deformable and can be made, for example, from an electrically conductive metal or an electrically conductive metal alloy.

Furthermore, the above-described at least one holder of the connector can be arranged on the contacting section.

A sealing element for sealing between the connector and the housing of the microphone unit can advantageously be arranged on the connector.

In particular, the sealing element can be arranged between the groove and a second end portion of the connector as seen in the axial direction of the connector, the cable exiting from the second end portion of the connector. In other words, seen in the axial direction of the connector, the sealing element can be arranged further outwards in relation to the housing than the groove and/or the at least one contacting element in the mounting position of the microphone unit and the loudspeaker unit.

The interior of the housing of the microphone unit can thus be effectively protected from environmental influences such as moisture and/or dust from the direction of the loudspeaker unit by means of the sealing element in the mounting position of the microphone unit and the loudspeaker unit.

For example, the sealing element can be designed as an O-ring, which can be accommodated or accommodated in a groove running around in the circumferential direction of the connector.

Advantageously, the sealing element designed as an O-ring can be easily replaced in the event of wear and/or a decreasing sealing effect.

As an alternative or in addition to this, the sealing element can be molded onto the connector, in particular running around in the circumferential direction of the connector, and in particular can contain an elastomer.

Advantageously, the sealing element formed in one piece with the connector in this way can be precisely adapted to a gap existing between the housing and the connector in the mounting position of the microphone unit and the loudspeaker unit, and thus an improved sealing effect can be achieved compared to a separately formed O-ring.

In particular, a stop for the housing of the microphone unit, which protrudes in the radial direction of the connector, can be formed on the second end section of the connector.

The stop can be formed at least partially in the circumferential direction of the connector.

By means of the stopper, the connector can be inserted into the housing to an appropriate extent in a mounting position of the microphone unit and the loudspeaker unit in order to effectively lock the housing with the holder and to effectively secure the connector to the housing.

A further aspect of the invention relates to the use of a connector as described above for connecting a microphone unit and a loudspeaker unit of a hearing device as described above.

The advantages of using the connector result analogously from the features mentioned for the hearing aid described above and their advantages.

• einem Verbinder, der zum lösbaren Verbinden des Kabels mit dem Gehäuse an einem dem Lautsprecher entgegengesetzten zweiten Ende des Kabels angeordnet ist, wobei das Verbindungselement separat ausgebildet ist und/oder unverlierbar an dem Gehäuse der Mikrofoneinheit angeordnet ist.

Also disclosed is a system for connecting a microphone unit and a speaker unit of a hearing aid to be worn on the ear, comprising:

• a housing of the microphone unit with at least one microphone, the housing being worn on the ear when in use,
• a cable, at the first end of which a loudspeaker of the loudspeaker unit can be connected and
• a connector arranged at a second end of the cable opposite the loudspeaker for detachably connecting the cable to the housing, wherein the connecting element is formed separately and/or is arranged captively on the housing of the microphone unit.
