Definitions

  • the present invention relates to a hearing aid with a contact spring arrangement according to the preamble of patent claim 1.
  • Known hearing aids are often switched on and off not by an additional switch, but by a swiveling battery charger.
  • the two usual contacts are installed in relation to the battery drawer in the hearing aid that both only touch the battery when it is fully pivoted into the hearing aid housing.
  • the hearing aid In this first position (“on” position) the hearing aid is switched on, i.e. all hearing aid components that have to be supplied with power (including the hearing aid amplifier part) are live.
  • the swiveling battery drawer has two additional swivel positions. In a second, somewhat swiveled-out position (“off” position), the battery touches at most one contact spring, but cannot be removed or fall out since the battery drawer only partially protrudes from the housing.
  • This position corresponds to the completely switched-off state of the hearing device, since all hearing device components to be supplied with current (including the hearing device amplifier part) are switched off by the battery.
  • the drawer In a third position ("battery change" position), the drawer can be swiveled completely out of the hearing aid housing. The battery can be removed in this position.
  • EP-A-0 176 838 furthermore discloses a behind-the-ear hearing device which comprises a fold-down battery drawer with locking lugs / locking recesses at the distal end.
  • the nose / locking recess device is designed as a simple closure (not, for example, as an on and off switch) for the hearing aid. If several locking troughs were provided, the battery in the battery drawer would also wobble at least in the outer locking positions of the charging.
  • the object of the invention is to build a hearing aid with a particularly simple and space-saving latching device, in which the battery does not wobble in different switching positions.
  • Pressing with different spring force prevents the battery from wobbling even in different switching positions of the battery drawer.
  • the known hearing aids also have the disadvantage that in the "off" position all hearing aid components to be supplied with power are switched off at the same time. Remote control when switched off is therefore no longer possible; In addition, control data stored for the hearing aid can be lost after a data storage device has been switched off, which data would then have to be entered repeatedly each time the hearing aid amplifier part is switched on again (and not only when the battery is changed). This is prevented if a hearing aid is designed according to claims 2 or 3 or 23.
  • the adjustable contact spring is double-tongued. Switching between the first and second switching positions takes place via one tongue, while the other in these two switching positions is constantly on the battery. If the hearing aid is also designed according to claim 10, the double tongue attached to the battery ensures that the battery is pressed elastically against the flap bottom and at the same time against the first contact in the first and second switching positions, so that always a perfect contact without Wobbling of the battery is guaranteed.
  • Figures 1 and 2 show a hearing aid 1 to be worn behind the ear, its housing 2, in which the hearing aid components, such as Microphone, amplifier, handset, battery, etc., are arranged by means of a hook 4 behind the ear 5.
  • the hearing aid housing 2 is acoustically connected to the auditory canal of the ear to be supplied via the hook 4 as well as a tube 6 and an ear olive 8 (or any ear adapter) connected to the end of the tube and sitting in the auditory canal.
  • the hearing aid housing 2 comprises a first and a second side surface 10 and 12, a front surface 14 facing the ear when worn, a rear surface 16 facing away from the ear and a downward distal end surface 18.
  • a pivotable flap 20 is arranged as a battery drawer.
  • the flap 20 is designed as part of the hearing device housing in the sense that it comprises distal parts of the two side surfaces 10, 12, the front surface 14 and the front surface 18 of the hearing device housing 2.
  • a finger 22, which is firmly connected to the flap 20, is located on the end face of the flap 20. It protrudes approximately half from the end face 21 of the flap 20 that is fully folded over the end face 18 of the hearing device housing 2 in the direction of the rear surface 16 of the hearing device housing 2.
  • a bead-shaped latching nose 25 runs across the inner surface 24 of the finger 22.
  • the latching nose 25 optionally snaps into one of two latching troughs 26, 28 which are arranged parallel to one another on the end face 18 of the hearing device housing 2 , a.
  • the locking recesses on the finger and the locking lug can also be arranged accordingly on the end face of the housing.
  • FIGS. 3, 4 show an enlarged view of the distal end of the hearing aid housing 2 with the flap 20 as a battery charger, the locking lug / locking recess mechanism 22 to 28, which enables the hearing aid to be switched on and off without using additional switches, and the contact spring arrangement 36, 38 , 44 to 48.
  • the detent 25 of the finger 22 snaps into the first detent depression 26.
  • the flap 20 is fully folded onto the hearing device housing 2.
  • a battery 30 is seated firmly in a recess 32 in the battery drawer 20.
  • the battery 30 contacts a first contact spring 36.
  • the large battery area 39 forming the negative pole contacts a first tongue 44 of a double-tongued second contact spring 38. This presses the battery 30 elastically into the recess 32 of the battery drawer 20, whereby the battery contacts the first contact spring 36.
  • the battery 30 also simultaneously presses the second contact spring 38 in the direction of the rear surface 16 of the hearing device housing 2.
  • a second tongue 46 of the double-tongued second contact spring 38 lies against a contact track 48 which is electrically connected via a line connection 50 a first group 52 of hearing aid components, which in particular also include the hearing aid amplifier part.
  • the first group 52 of hearing aid components is also electrically connected to the first contact spring 36 via a further line connection 54.
  • the circuit is thus closed via the first group of hearing aid components, in particular the hearing aid amplifier part.
  • the circuit is also closed via a second group of hearing aid components 56, which in particular also includes a remote control part and a data memory, because the first contact spring 36 via a line connection 58 and the second contact spring 38 via a line connection 60 with the second group 56 from Hearing aid components are connected.
  • a second group of hearing aid components 56 which in particular also includes a remote control part and a data memory, because the first contact spring 36 via a line connection 58 and the second contact spring 38 via a line connection 60 with the second group 56 from Hearing aid components are connected.
  • all groups 52 and 56 of hearing device components that are to be supplied with current are thus jointly connected to the battery.
  • the detent 25 of the finger 22 engages in the second recess 28.
  • the first tongue 44 of the double-tongued second contact spring 38 continues to contact the large battery area 39 of the battery 30 and thus continues to press the battery 30 elastically in the Recess 32 of the flap 20.
  • the battery 30 is therefore still firmly attached to the first contact spring 36.
  • the hearing aid amplifier part in particular is now switched off; however, the components of the second group 56 of hearing aid components, in particular the remote control part and / or data storage, remain switched on on the battery 30, because contact with the battery 30 via the first contact spring 36 and the line connection 58 and the second tongue 44 of the second contact spring 38 and the line connection 60 continues to exist.
  • FIG. 5 shows the flap 20 in the fully open position.
  • a battery 30 can be placed in the recess 32 of the flap 20 or removed from the flap 20.
  • the jacket 33 of the battery 30 thereby remains in contact with the first contact spring 36, the second contact spring is 38 decoupled from the second large battery area 39 in this position, so that no current can flow. The device is therefore completely switched off.
  • the flap 20 is closed by being pivoted toward the housing 2 about a pivot axis 40 perpendicular to the side surfaces 10, 12 of the hearing device housing 2.
  • the locking lug 25 of the finger 22 must be pressed with an increased force on an increase 42 on the end face 18.
  • the increase 42 prevents the flap from being opened unintentionally when the flap 20 is closed.
  • the flap 20 serving as a battery drawer can be folded down again by the wearer of the hearing aid e.g. grips the rear end of the finger 22 with the thumb and folds the flap back into the respectively desired position by pulling the finger back.
  • the battery 30 is located in the flap 20 distally across the side surfaces 10, 12 of the housing 2 and is folded up, that is to say not pivoted in as in many conventional hearing aids. As a result, the battery 30 cannot fall out of its own accord when the hearing aid 1 is directed distally upward when the flap 20 is folded down.
  • the second tongue 44 of the double-tongue contact spring 38 clearly stands out from the battery recess 32 in this flap state. When the battery 30 is pivoted into the housing 2, the contact springs cannot hook onto the battery.
  • the present contact spring arrangement eliminates the danger that often existed in earlier hearing aids, namely that the contact springs were slightly bent due to frequent opening and closing.
