  • a hearing device here means any sound-emitting device which can be worn on or in the ear or on the head, in particular a hearing aid, a headset, headphones and the like.
  • 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), hearing aid with external receiver (RIC: receiver in the canal) and in-the-ear hearing aids (IDO), e.g. Concha hearing aids or canal hearing aids (ITE, CIC).
  • BTE behind-the-ear hearing aids
  • RIC hearing aid with external receiver
  • IDO in-the-ear hearing aids
  • ITE 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 are installed for recording the sound from the environment.
  • a signal processing unit 3 which is also integrated 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 the signal processing unit 3 is effected by a likewise integrated into the hearing aid housing 1 battery. 5
  • Hearing aids usually have a battery compartment in which the hearing aid battery is housed.
  • This battery compartment can usually swing out of the hearing aid housing. In an open position of the battery compartment, the battery can be removed from the battery compartment. In the closed position of the battery compartment, the battery compartment is pivoted into the housing and the battery is in contact with the hearing aid electronics.
  • the battery compartment often has a small projection whose purpose is to be able to open the battery compartment easily with your fingernail.
  • the inadvertent or unwanted opening of the battery compartment of a hearing aid should be prevented. This is necessary to prevent the possible ingestion of the battery in the battery compartment by a toddler.
  • hearing aids are known in which a force of less than 10 N is sufficient to open the battery compartment.
  • This known solution consists of a displaceable in the axial direction by means of a small screwdriver bolt which is mounted on an axle. Latch and axle are part of the battery compartment, which also holds the battery. The bolt receives its abutment through one of two housing pins, which can also be used for switching on / off the hearing aid by means of battery compartment.
  • the object of the present invention is thus to better lock the battery compartment of a hearing device against unwanted opening.

Due to this inclination, the securing element is pulled firmly into the secured position when an attempt is made to open the battery compartment, but the securing element is in the secured position. In addition, it is possible by this low inclination locking of the fuse element to a round housing projection.
  • the securing element may have a pressure surface against which the projection of the housing presses when the battery compartment is moved in the closed position, so that the securing element is pressed into the unlocked position becomes. This gives the user a tactile or visual signal that the battery compartment is not yet secured when it has closed.
  • the securing element may also have a stop which stops the movement of the securing element when pivoting in the unlocked position. This can ensure that the fuse element can only be swung out of the battery compartment to a certain extent.
  • a battery compartment 10 is shown as a one-piece injection molded part. Furthermore, the figure shows in exploded view a securing element and a shaft or a pin 30, with which the securing element 20 can be pivotally attached to the battery compartment 10.

They are just the elements of FIG. 2 shown in the assembled state and electrical battery contacts 40 and additionally a pin or projection 50 of a hearing aid housing or a housing shell. In addition, a portion of a housing shell half 60 in the region of the battery compartment is indicated for orientation.
  • FIG. 3 shows the battery compartment 10 in the closed position in side view. This means that the central axis of the cylindrical battery compartment 10 extends approximately through the center of the battery contact 40.
  • the projection 50 of the second housing shell half, not shown, has penetrated to the bottom of the pocket-shaped recess 13 of the battery compartment 10. It limits the movement of the battery compartment 10 at the closed position.
  • the securing element 20, which is pivotally mounted on the pin 30, is in the secured position. This means that the battery compartment 10 is secured against accidental opening.
  • the retaining surface 25 of the securing element 20 engages behind the projection 50 of the housing or the housing shell half.
  • the holding surface 25 defines a plane on one side of the projection 50 and on the other side of the axis of rotation of the battery compartment 10 is located. Ie. this holding plane is slightly inclined relative to that which is spanned by the contact point or the contact surface between the holding surface 25 and projection 50 and the axis of rotation of the battery compartment 10.
  • This inclination ( ⁇ 30 °, in particular ⁇ 10 °, causes the wedge-shaped projection 27 with the retaining surface 25 of the securing element 20 to pull the entire securing element 20 even more strongly into the secured position when attempting to open the battery compartment 10.
  • the case is counteracted in that the securing element 20 is pressed into the unlocked position in an attempt to open the battery compartment 10.
  • the battery compartment of FIG. 3 is in FIG. 4 shown in an oblique view.
  • the operating surface 22 of the securing element 20 can be seen here. It is in the secured position flush with the surface of the battery compartment 10.
  • the securing element 20 forms with the recess 18 a slot through which a small screwdriver into the pocket 23 (in FIG. 4 not visible) of the securing element 20 can engage in order to move the securing element 20 in the unlocked position.
  • the battery compartment 10 is still shown in the closed position, ie, the projection 50 is located at the bottom of the pocket-shaped recess 13.
  • the fuse element 20 is pivoted out of the battery compartment 10 and is in the unlocked position.
  • the wedge-like projection 27 of the securing element 20 no longer engages behind the projection 50 of the housing.
  • the stop 24 bears against the wall of the pocket-shaped recess 13 below the grip element 12.
  • the projection 16 holds the battery compartment 10 still engaged in the closed position.
  • the battery compartment can be released with some pressure from this latching and the pocket-shaped recess 13 is open to the outside.
  • FIG. 6 is the condition of the battery compartment of FIG. 5 shown in the oblique view. While the representation of the projection 50 is omitted here, in the image, the pocket 23 of the securing element 20 can be seen well, in which a screwdriver can engage in order to unlock the securing element.
  • FIG. 7 is now shown the state that the battery compartment is moved from the closed position to an open position. This means that the projection 50 has been pressed over the projection 16 in the pocket-shaped recess 13 and is already here at the outlet of the recess 13.
  • FIG. 8 again shows the battery compartment 10 of FIG. 7 in an oblique view.
  • the battery compartment 10 is partially open, so that there is a clear gap between the grip element 12 and a portion 61 of the housing 60 or the housing shell half.
