  • a sound tube from a loudspeaker or earpiece to an ear piece.
  • the earpiece e.g. a so-called dome
  • a volume changeable element e.g. an inflatable in-ear balloon to install. This leads to a better hold of the earpiece in an ear canal.
  • an additional channel from a pump must be directed to a volume changeable element, for example the in-ear balloon of the earpiece, in order to inflate it with air or another medium.
  • the pump for this purpose can be arranged in the hearing aid unit or at an ear-side end of the sound tube. Also possible is a placement of the pump in the earpiece itself.
  • a pump for example, a conventional used in hearing aids speakers, a so-called receiver can be used.
  • a problem with such embodiments is to remove the air pumped into the volume-changeable element, or the medium used in each case, from it again. It is an object of the present invention to improve the removal of air or other medium from a volume changeable element.

  • a filling mechanism designed for pumping conveys the medium through the channel means to the volume changeable element.
  • an outlet mechanism designed for pumping is provided, which actively carries away the medium from the volume-changeable element through the channel device.

  • other fluids or gases may be used.
  • the filling mechanism is either a first of two pumps or the inflation movement of the membrane of a single pump.
  • the outlet mechanism is either the second of two pumps or the pumping motion of the membrane of a single pump.
  • a first valve arrangement preferably controls a feed flow of the medium from the filling mechanism to the volume-changeable element. More preferably, a second valve arrangement controls a discharge flow of the medium from the volume changeable element to an outlet.
  • the first valve arrangement releases a supply flow from the filling mechanism to the volume changeable element. Accordingly, the second valve arrangement releases the discharge flow from the volume changeable element to the outlet.
  • a valve assembly may be a single valve or a group of multiple valves.
  • the first valve arrangement and the second valve arrangement are each separately, ie individually controllable. That is, they can release the flows independently of each other. In this way, the degree of freedom and thus the flexibility is increased.

  • a manual unlocking of one of the valves can be accomplished, for example, to initiate a vent of the volume changeable element directly from the user.
  • At least one of the valve arrangements is controlled by means of a trapezoid drive.
  • Trapezoidal drives are also known as pantograph drives. This type of valve control allows a constructive space savings.
