Definitions

  • the present disclosure relates to a hearing device with a closure mechanism, and in particular to a hearing device with a battery door for accommodating and/or supporting a battery in the hearing device.
  • a focus in the hearing aid industry is to make hearing aids smaller and more discrete for the benefit of the user and thus a design which can decrease the size of the hearing aid is of importance. Further, it is of great interest from a cost perspective that designs are easy and cheap to manufacture.
  • a button battery is used in a hearing device and traditionally a battery door of a hearing aid has been fitted with a locking mechanism leading to bulky hearing devices, a complex manufacturing process and/or high failure rate of the locking mechanism.
  • hearing device parts must be robust and resistant to wear. Further, precise fitting of moving parts is desired for improving the user experience.
  • a closure mechanism is arranged as far from the pivot axis as possible to reduce the mechanical stress on parts of the closure mechanism.

  • the first normal angle 74 between the first primary principal direction 70 and the first primary normal 72 is shown to be non-perpendicular, thereby providing support of the first arm 30 when engaged in the first primary recess 38 and when engaged on the first primary surface 48.
  • the second normal angle 80 between the second primary principal direction 76 and the second primary normal 78 is shown to be non-perpendicular, thereby providing support of the second arm 60 when engaged in the second primary recess 40 and when engaged on the second primary surface 54.
  • Magnitude of the normal angles 74, 80 is determined by the geometry of the engagement member 22 and displacements of the first arm 30 and the second arm 60 when the engagement member 22 is advanced from the closed position to a position between the closed position and the open position.
  • the magnitude of the normal angles 74, 80 may be less than 90°, such as less than 85° and/or in the range from 45° to 89°, such as in the range from 60° to 88°, such as in the range from 75° to 88°.
