Definitions

  • the present invention relates to a hearing device with a housing and a battery holding device or a battery compartment, which is attached to the housing.
  • a hearing device is understood here to mean, in particular, a device that can be worn on the head, such as a hearing device, a headset or a headset.
  • Hearing aids are portable hearing aids that are used to care for the hearing impaired.
  • different types of hearing aids such as behind-the-ear hearing aids (BTE) and in-the-ear hearing aids (ITO), e.g. also Concha hearing aids or canal hearing aids (CIC), provided.
  • BTE behind-the-ear hearing aids
  • ITO in-the-ear hearing aids
  • CIC canal hearing aids
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually integrated in a signal processing unit. This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid. In a hearing aid housing 1 for carrying behind the ear, one or more microphones 2 for receiving the sound from the environment are installed.
  • a signal processing unit 3 also in the hearing aid housing 1, processes the microphone signals and amplifies them.
  • the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
  • the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
  • the power supply of the hearing device and in particular of the signal processing unit 3 is carried out by a likewise integrated into the hearing aid housing 1 battery. 5
  • the battery of a hearing aid is often in a so-called battery door or a battery compartment, which serves as a battery holding device.
  • the battery is inserted in this battery door. Subsequently, it is pivoted into the hearing aid housing, snapped or otherwise secured.
  • This requires mechanical structures that wear out over time. Accordingly, numerous battery replacement operations lead to high wear, which adversely affects the retention mechanism or the insertion, snapping or Einschwenk mechanism.
  • a signal transmission device can be releasably attached to the hearing aid by means of a magnetic holder.
  • the object of the present invention is therefore to propose a hearing device in which numerous battery replacement cycles are possible and the wear remains as small as possible.
  • this object is achieved by a hearing device with a housing and a battery holding device which is fixed to the housing, wherein the battery holding device is inserted into an opening of the housing, between the housing and the battery holding device, a releasable magnetic connection, the main force component extends in the insertion direction ,
  • the magnetic attachment of the battery holding device to the housing of the hearing device that always a constant holding force between the battery holding device and the housing can be achieved. It also does not change in numerous removal and Wiederereinsetzvor réellen of batteries. In particular, so that virtually mechanical wear can be prevented.
  • the opening in the housing is slot-shaped and open on two sides, so that the battery holding device can be held on these two sides when inserted into the opening.
  • This provides a simple mechanical guidance, so that the magnetic binding can be achieved in a targeted manner.
  • the battery holding device may have two projections and the housing as a guide have two grooves in which the projections are guided during insertion.
  • a mechanical guide can be achieved, which supplies the magnetic elements to each other.
  • a mechanical guidance can be achieved, which allows only a one-dimensional movement.
  • the hearing device according to the invention may optionally be equipped instead of the battery holding device or the battery door with a replacement module which has the same outer dimensions as the battery holding device and which can be inserted into the opening instead of the battery holding device.
  • a replacement module which has the same outer dimensions as the battery holding device and which can be inserted into the opening instead of the battery holding device.
  • the replacement module may have an audio input functionality, wherein corresponding electrical plug contacts for mutual contacting are arranged on the replacement module and in the opening of the housing.
  • a cavity whose bottom is profiled in the insertion direction may connect to the opening in the housing, a cavity whose bottom is profiled in the insertion direction.
  • a reverse polarity of the battery can be prevented if the battery holder can attach only in exactly one position to the battery case.
  • Another advantage of this profiling may be that the battery holder can not be moved perpendicular to the magnetic force. This increases the hold of the battery holding device in the housing. Specifically, it is advantageous if the bottom of the cavity is concave. As a result, the battery holding device or the replacement module can be rounded, so that it can be handled comfortably.
  • a magnet may be disposed on the housing on a perpendicular to the opening through the center thereof. As a result, the battery holding device is held centrally in the opening.
  • the magnet is much smaller than the opening.
  • the surface of the magnet, viewed in Insertion direction is less than 20 percent of the opening in the housing.
  • a hearing aid housing 10 which has at its end a slot-shaped opening 11 for insertion of a so-called "battery door" 12.
  • the insertion or removal direction is in FIG. 2 marked with the arrow 13.
  • the bottom 14 of the opening 11 of the hearing aid housing 10 is concave here. In the center of the bottom 14 at its lowest point a first magnetic element 15 is arranged. Its dimensions from the perspective of the insertion direction 13 are relatively small compared to the dimensions of the opening eleventh
  • the battery door 12 has a receptacle into which a battery 16 is inserted.
  • the battery door 12 has a first surface portion 17, which corresponds to the bottom 14 in the hearing aid housing 10 and is correspondingly convex.
  • the battery door 12 also has a second surface portion 18 that has the contour of the corresponding part of the hearing aid housing 10.
  • a second magnetic element 19 is arranged, which attracts the first magnetic element 15 in the hearing aid housing 10.
  • At least one of the two magnetic elements 15, 19 is a magnet.
  • the other magnetic element is then either ferromagnetic or a magnet with opposite polarity.
  • FIG. 3 the front of the hearing aid housing 10 and the battery door 12 is shown.
  • the slot-shaped opening 11 is clearly visible.
  • the magnetic element 15th is the magnetic element 15th
  • the battery door 12 is below the battery housing 10 in FIG FIG. 3 shown. Due to the view from the front side, the second magnetic element 19 is shown in dashed lines there.
  • the slot-shaped opening 11 is during insertion of the battery door 12 into the opening 10 is a mechanical guide, based on FIG. 3 , does not allow a degree of freedom in the horizontal direction. A movement of the battery door 12 in the vertical direction would still be possible.
  • the hearing aid housing 10 has the inner sides of the opening 11 guide grooves 20 which extend in the insertion direction 13.
  • the battery door 12 has this matching protruding guide elements 21. These are when inserting the battery door 12 in the grooves 20 of the hearing aid housing 10 out. Therefore, a movement of the battery door 12 is prevented in the vertical direction. This means that the battery door 12 during insertion can only move in one direction 13, ie in one dimension. Consequently, the magnetic member 19 is accurately supplied to the magnetic member 15, so that the magnetic connection can be made safe and easy.
  • FIG. 4 shows the state in which the battery door 12 including battery 16 is inserted into the hearing aid housing 10.
  • the two magnetic elements 15, 19 are bonded together by magnetic forces.
  • the surface of the hearing aid housing 10 is flush with that of the battery door 12.
  • the removal of the battery door 12 is easy to achieve by pulling the battery door 12 from the opening 11 in the reverse direction.
  • the battery door 12 for example, with two fingers on the free surfaces 22 engage (see. FIGS. 2 and 3 ).
  • the surfaces can be designed accordingly grip.
  • the battery door 12 may in the opening 11 of the hearing aid housing 10 and a in FIG. 5 illustrated replacement module 30 are used.
  • This also has a corresponding surface portion 31, which corresponds to the bottom 14 of the opening 11.
  • a magnetic element 32 is provided on this surface section 31 in order to be able to produce the corresponding magnetic connection with the magnetic element 15.
  • the magnetomechanical interface of the replacement module 30 is therefore the same as that of the battery door 12.
  • the replacement module itself can have any function. For example, it can be configured as an audio shoe or computer interface, Bluetooth interface and the like.
