  • the invention has the object to provide a hearing aid, which allows adaptation to different operating conditions, ie different acoustic environments, while providing a far-reaching protection of the sensitive is adjustable and can be adapted to the dimensions of the ear.
  • WO 00/45617 A3 From the WO 00/45617 A3 is a hearing aid with a metal existing housing known that completely surrounds the electronics of the hearing aid and wherein a sound outlet opening is closed with an acoustically transparent, waterproof film.
  • the invention has the object to provide a hearing aid, which allows adaptation to different operating conditions, ie different acoustic environments, while providing a far-reaching protection of the sensitive electronic components from moisture ingress.
  • the object is achieved by a hearing aid according to claim 1.
  • the hearing aid according to the invention has a first housing part, which is carried by the user behind the ear together with the second housing part.
  • an electrical energy source for example, a lithium-polymer battery, a zinc-air battery or a capacitor is installed. This supplies an electronic component with electrical energy, which is located in the second housing part.
  • An electronic component in the sense of this invention may be an electronic amplifier circuit, a noise generator, an A / D or D / A converter or a digital signal processor. These circuits can be implemented discretely or integrated. The exact function of the electronic component is adapted to the needs of the user. For changing operating conditions, the electronic component has at least two different operating states. For example, a first operating state with a first gain and a second operating state with a second, higher or lower, gain can be provided. However, it is also possible to switch the directional characteristic of a receiver microphone or provide a plurality of frequency filters that can be selected by the user.
  • a selection device For selecting at least two operating states of the electronic component, a selection device is available, which has an external operating element.
  • This control element can be arranged in the first housing part or in the second housing part.
  • the selector is a potentiometer which controls the gain of an analog amplifier. In order to prevent penetration of moisture by the operating element, this is arranged liquid-tight on the outside of the housing part.
  • the axis of a potentiometer may be provided with an O-ring seal. Alternatively, slip ring seals or labyrinth seals are possible.
  • the selection device is a mechanical switch, its operating element can be sealed by means of a bellows. A pressure switch can be operated through an elastic housing part. Thus, the waterproofness of the hearing aid is not degraded by the external control. Nevertheless, the user gains in ease of use by being able to adapt his device to different operating conditions.
  • the hearing aid according to the invention has a third housing part which conducts an acoustic stimulus into the auditory canal of the user.
  • this may be a simple tube, which forwards the sound from a sound transducer integrated in the second housing part.

  • more electronic components are arranged in the third housing part.
  • a sound-permeable membrane at the top of the third housing part.
  • the tip is the one end of the housing part called, which is closest to the ear canal.
  • a membrane can be made, for example, from expanded polytetrafluoroethylene. This is permeable to sound waves, which are generated in the second or third housing part. Likewise, the membrane is permeable to gaseous water vapor. The penetration of liquid water, cerumen or sweat is reliably prevented. Thus, the third housing part remains clean and dry inside and the durability and reliability of the hearing aid is increased.
  • the hearing aid according to the invention can only generate noise as a tinnitus masker or, as an amplifier, record ambient noise through a microphone and release it back into the auditory canal of the user through a sound transducer.
  • a microphone opening is provided in one or more housing parts.
  • a microphone opening is provided in the second housing part.
  • the microphone opening is also sealed with a waterproof membrane.
  • these openings are also included in one embodiment a partially permeable membrane which allows air to penetrate and at the same time is impermeable to liquid water.
  • this membrane is preferably located substantially on the surface defined by the boundary line of the opening. As a result, the opening is closed with a taut membrane without bag-like protrusions of the membrane are present.
  • a further waterproof membrane is provided on the connecting surface between the first and the second housing part.
  • This may also consist of expanded polytetrafluoroethylene or, if the permeability to water vapor is secondary, of any other material.
  • the electronic components In order to allow easy accessibility of the electronic components, for example, for maintenance, they are mounted on a frame in one embodiment.
  • the outer shape of this frame is complementary to the inner shape of the second housing part.
  • the waterproof membrane for sealing the second housing part is particularly preferably arranged on the bottom surface of the frame facing the first housing part.
  • the hearing aid after FIG. 1 has a first housing part 1, a second housing part 2 and a third housing part 3.
  • a screw 4 which is made liquid-tight by means of an O-ring seal between the first and the second housing part.
  • a screw 5 Between the second housing part 2 and the third housing part 3a is also a screw 5, which also has a seal.
  • the screw 4 and 5 also bayonet locks or, in elastic housing material, plug-together closures can be performed.
  • the housing parts themselves consist of a metal or an alloy or a plastic. Depending on the requirements of the plastic, it may be a thermoplastic or a thermoset. The plastic can be made soft and cuddly to increase the wearing comfort or hard so as to better protect the electronic components inside the hearing aid.
  • FIG. 1 shows two different embodiments of the third housing part 3a and 3b.
  • Housing part 3a contains itself no active components.
  • the acoustic stimulus is generated by the electronic components in the housing part 2 and passed through the housing part 3 a in the auditory canal of the user.
  • a waterproof membrane 16 located at the top 6 of the housing part 3 a waterproof membrane 16. This prevents the entry of at least liquid water into the housing part 3 a.
  • the membrane can in return at least the sound from the housing part 3a.
  • the membrane 16 also allows the escape of water vapor from the housing part 3a.
  • the alternatively usable housing part 3b has a sound transducer 17 at its end remote from the second housing part. So that this as well as the electronic components in the housing part 2 and 1 are not damaged by moisture, is located at the opening of the housing part 3b a sound-permeable but waterproof membrane 16.
  • the transducer 17 is running through the housing part 3b connecting lines to the electronic component in Housing part 2 connected. Since the generated sound is not affected by resonances in the housing part 3a, results in the use of housing part 3b a higher sound quality.
  • FIG. 1 shows a selector 9 for selecting a plurality of operating states of the hearing aid.
  • the selector 9 may be a volume control.
  • a microphone opening 8 In order to absorb ambient noise, which are then further processed and amplified via the tip 6 and the sound transducer 17, located in the housing part 2 is a microphone opening 8. In order not to affect the water resistance, this microphone opening is closed by a sound-permeable and waterproof membrane.
  • the hearing aid is powered by a zinc-air battery. This requires sufficient air exchange to show no capacity losses.
  • openings 7 are provided in the housing part 1. Thus, the water-tightness of the housing is not affected by the openings 7, these are closed by means of a membrane, which is impermeable to liquid water. However, an exchange of air through the openings 7 is possible.
  • FIG. 2 shows an exploded view of the hearing aid FIG. 1 , Shown again are the 3 housing parts 1, 2 and 3.
  • the screw 4 between the first and second housing part is open.
