Description
Technical Field
The invention relates to a hearing instrument system, in particular a hearing assistance system or a hearing aid system.
Background
Hearing instruments are commonly used to output sound signals to the auditory system of a wearer of the hearing instrument. Here, the output of the sound signal is performed by an output transducer, and the sound wave is often performed on an acoustic path by a speaker (also referred to as "receiver" or "receiver"). Such hearing instruments are often used as so-called hearing aids (also referred to simply as hearing devices). For this purpose, the hearing instrument normally comprises an acoustic input transducer (in particular a microphone) and a signal processor (also referred to as control unit) which is provided for processing the input signal (also referred to as microphone signal) generated by the input transducer from the captured ambient sound in such a way by using at least one signal processing algorithm which is usually stored and/or adapted specifically for the user, in order to compensate at least partially for a hearing loss of the wearer of the hearing instrument. In particular in the case of hearing aids, the output transducer can alternatively also be a so-called bone conduction earpiece or cochlear implant, which is provided for mechanically or electrically coupling the sound signal into the auditory system of the wearer, in addition to the loudspeaker. Hearing assistance devices are typically used in the form of hearing assistance devices that require at least partial wear behind the ear (abbreviated "hdO") and hearing assistance devices that require full or partial wear in the ear canal (abbreviated "idO" or "initial"). The term "hearing instrument" also includes, for example, so-called Tinnitus masks (tinnitius-Masker), headphones, headsets and similar instruments, among others.
In order to provide power to the electronic components of the hearing instrument, such as the signal processor, the respective microphone, speaker and the like, conventional hearing instruments usually have a battery, which must be replaced periodically. But also rechargeable batteries (also called accumulators) are used in modern hearing devices. However, since the energy density of the battery is usually relatively low, the battery must be charged correspondingly more frequently. These rechargeable batteries, in particular the charging electronics associated with the batteries, are usually galvanically connected to an energy source for charging purposes. In this case, the respective hearing instrument is connected for charging to a specific charging cable. Such charging cords usually have a plug of relatively complex design, for example a click plug (Klinkenstecker) or a miniaturized USB plug, which must be arranged on the hearing instrument next to other functional elements of the hearing instrument, for example a button or switch for volume adjustment or other hearing instrument controls.
Disclosure of Invention
The invention is based on the object of providing a particularly simple charging of rechargeable batteries.
This object is achieved according to the invention by a hearing instrument system. Further advantageous embodiments and further developments of the invention which are inventive in part per se are set forth in the description below.
The hearing instrument system according to the invention comprises a hearing instrument, in particular a hearing assistance device (also referred to as "hearing device" for short). The hearing instrument has at least a control unit provided for processing an audio input signal into an audio output signal. Furthermore, the hearing instrument has a rechargeable battery for supplying the control unit with energy. The hearing instrument further has a housing in which the battery and the control unit are arranged. Furthermore, the hearing instrument has buttons for inputting control signals to the control unit, which buttons are preferably arranged such that they are accessible to a user of the hearing instrument from outside the housing. Furthermore, the hearing instrument has at least one connector for electrically connecting the battery with a source of charging energy. In this case, buttons for inputting (in particular on the user side) control signals (for example for switching the hearing instrument on or off) are integrated into the connector. Further, the connector magnetizes the connector mating piece for magnetically holding the charging cord.
The control unit is a "Controller", which is at least designed and arranged for processing the audio input signal. Optionally, the controller is also designed and arranged for controlling the charging process of the rechargeable battery. The controller preferably has at least one microcontroller and an associated data memory, in which a program for processing the audio input signal is stored on the basis of software technology. Alternatively, the controller has at least one application-specific chip on which the aforementioned program is implemented by means of circuit technology.
The audio input signal and the audio output signal are understood here and below as electrical signals which reflect sounds in the audible frequency range. Optionally, the hearing instrument has at least one microphone and/or a corresponding signal interface (for receiving an audio input signal, e.g. an antenna or similar means) for generating an audio input signal. For converting the generated audio output signal, the hearing instrument preferably has a loudspeaker, but may alternatively have means for mechanically or electrically stimulating the auditory system of the hearing instrument user.
Since the push button is integrated in the connector, it is advantageously possible to save installation space on the hearing instrument and thus also to provide installation space for other functions or for miniaturization of the hearing instrument, if necessary. Due to the magnetic holding of the connector fitting, mechanical holding means, in particular latching means for latching the connector fitting to the connector or to the housing of the hearing instrument, which are often subject to wear, can be dispensed with.
In a preferred embodiment, the connector has a circular outer contour. The push button is in this case surrounded, in particular, in a circular ring shape by the contact surface of the connector. Thus, the contact surfaces of the button and the connector are preferably arranged concentrically. This also makes it possible to achieve a particularly simple contacting of the connector by means of the connector fitting, since the connector fitting can be attached to the connector in a freely rotatable manner by 360 degrees due to the circular outer contour. The risk of damage to the connector and/or the connector fitting due to e.g. rectangular or trapezoidal geometry is reduced.
In a further preferred embodiment, the hearing instrument system also has the aforementioned charging cable. The connector fitting of the charging cable is magnetized for likewise magnetic fastening to the connector of the hearing instrument.
For magnetization of the connector and/or the connector counterpart, the connector and the connector counterpart have, for example, solid permanent magnets. Alternatively, the connector and the connector counterpart preferably have complementarily shaped, injection-molded and thus plastic-bonded permanent magnets.
In an embodiment which is advantageous with regard to saving construction space, the connector of the hearing instrument has a first contact surface and a second contact surface of a different polarity (gegenpolig) than the first contact surface. The second contact surface is preferably arranged concentrically with the first contact surface and is electrically insulated from said first contact surface. The term "different polarity" is understood here and below to mean, in particular, that the second contact surface is provided with a different potential than the first contact surface during a defined charging operation of the hearing instrument. In this case, therefore, only one connector and therefore also only one connector counterpart is required for the "complete" connection of the rechargeable battery to the charging energy source.
Preferably, the connector fitting of the charging cord is designed complementarily to the connector. The connector fitting of the charging cable therefore has two fitting contacts arranged concentrically to one another for two contact surfaces.
In a particularly expedient further development, the second contact surface of the connector forms a part of the push button which can be operated by a user of the hearing instrument, preferably movable. The second contact surface here forms, for example, the tip of a "push rod" of the push button, which must be moved, in particular pressed, by the user of the device in order to trigger a corresponding control signal.
In an alternative embodiment, the hearing instrument has a further (second) connector. In this case, both connectors each have (only) one contact face. Furthermore, the two connectors are provided as described above for magnetically holding one connector counterpart of the charging cord, respectively.
In a preferred embodiment, during a defined charging operation, a connector counterpart of the charging cable is connected to each of the two connectors, and each of the two connectors is connected to a different potential.
Suitably, the aforementioned charging cord also comprises two connector fittings designed and arranged for connection with two connectors of a hearing instrument.
In this case, the charging cable is preferably of Y-shaped design and has a "trunk section" and two branch sections which originate from the trunk section and carry the respective connector fitting at the end face. For connection to a charging energy source, the charging cable has a USB connector arranged on the trunk section. The charging cable is thus a USB charging cable which is designed and provided, for example, for connection to a USB port of a computer or to a corresponding buck converter which is designed and provided for converting a supply voltage provided by the public power grid into a charging voltage for a rechargeable battery.

Detailed Description
Parts and dimensions corresponding to one another are always provided with the same reference numerals in all figures.
In fig. 1 a hearing instrument, in short a "hearing device 1", is shown. The hearing instrument 1 comprises a housing 2 in which a number of electrical components of the hearing instrument 1 are arranged. These components are constituted in particular by two microphones 3, a control unit 4 and a loudspeaker 6. Microphone 3 is used in the intended operation of hearing device 1 to generate an audio input signal S from the ambient sound of hearing device 1A. The audio input signal is transmitted to the control unit 4 and converted by the control unit into an audio output signal S under execution of the stored signal processing algorithmLThe audio output signal is output to a speaker 6. Audio output signal SLIs output by the loudspeaker via the sound tube 8 and the ear adapter 10 to the auditory system of the user of the hearing device 1. In order to power the electrical components, the hearing device 1 has a rechargeable battery 12. In the embodiment shown, the charging and conversion electronics 14 are integrated in the control unit 4.
For inputting control commands into the control unit 4, the hearing instrument 1 has buttons 16 that are accessible from the outside of the housing 2. In order to connect the battery 12 to a charging energy source during a defined charging operation, the hearing instrument 1 also has a connector 18. The connector 18 is designed and arranged here for magnetically holding a connector counterpart 20 of a charging cable 22 (see fig. 2). The connector 18 has a circular outer contour. The connector counterpart 20 of the charging cable 22 is designed complementary to the connector 18.
In the exemplary embodiment according to fig. 1, the connector 18 has a first contact surface 24 which is designed in the form of a circular ring and a second contact surface 26 which is surrounded by the first contact surface 24 and is therefore arranged concentrically thereto. The second contact surface 26 is a top portion of the push button 16 that is accessible from the outside. The two contact surfaces 24 and 26 are electrically insulated from one another and serve to contact two charging contacts of the battery 12 which are at different potentials. In the exemplary embodiment according to fig. 1, therefore, only one connector 18 is provided.
In the embodiment according to fig. 2, the hearing instrument 1 has connectors 18 on both "flat sides 28", respectively. In this case, a push button 16 is integrated in one of the two connectors 18. In the present exemplary embodiment, however, each connector 18 has only one contact surface which, in the intended charging operation, is assigned to one of the two charging contacts which are at different potentials. In this case, the charging cord 22 also has two connector fittings 20.
In both embodiments according to fig. 1 and 2, the hearing instrument 1 and the charging wire 22 together form a hearing instrument system 30.
In both embodiments, the charging cord 22 also has a USB connector 32 at its end remote from the corresponding connector fitting 20.
The technical solution of the present invention is not limited to the foregoing embodiments. From the previous description, a person skilled in the art can derive other embodiments. In particular, the individual features of the invention described in relation to the different exemplary embodiments and their design variants can also be combined with one another in different ways.
