Definitions

  • Hearing aids are used to compensate for decreases in hearing in patients.
  • Hearing aids consist of one or more microphones, an electronic circuit which has at least one analogue or digital amplifier, and one or more loudspeakers and a power source for supplying these components.
  • Hearing aids are constantly exposed to the effects of liquids and dirt in practical use. These factors can be caused by a number of factors including sweating of the patient and earwax, environmental factors such as dust or the influence of water during swimming or other water sports, or when the patient accidentally drops the hearing aid into a vessel filled with water or other liquids.
  • hearing aids are designed so far waterproof, so that water ingress can not take place.
  • the disadvantage of this is, for example, that in the microphone and the speaker complex membrane arrangements are required to seal these areas and thereby to allow the sound wave transmission from / to outside the hearing aid.
  • a hearing aid comprising: at least a first electro-acoustic transducer for receiving sound waves and conversion into electrical signals, a by coating and / or A liquid-sealed electronic circuit for processing the electrical signals, at least one second electroacoustic transducer for converting electrical signals supplied to the circuit into sound waves and an electrical energy source sealed by coating and / or pouring against liquids.
  • the electro-acoustic transducers are constructed of materials which convert a change in shape into an electric and / or magnetic field and / or an electric current flow and / or an electrical voltage (and / or vice versa) and the insensitive to liquids, in particular water, salt water and light acids, are.
  • the hearing aid i. the at least two transducers (e.g., microphone and speaker), the electronic circuitry which provides signal processing and signal amplification, and the power source (e.g., battery or accumulator) are each insusceptible to water, and the case does not matter.
  • the housing does not have to be made waterproof, corresponding expensive measures can be advantageously eliminated.
  • electroacoustic transducers are: single or multilayer piezoelectret films and / or piezoelectric transducers, for example flexural vibrators or thickness oscillators.
  • the one or more electroacoustic transducer (s) acting as a microphone may alternatively be in the form of a hot wire microphone (s). While hot-wire microphones may fail while immersed in liquids, they will not be damaged and will be operational once the fluid has drained.
  • FIG. 1 1 schematically shows the block diagram of a hearing aid 100 with a first electroacoustic transducer or microphone 110 for receiving an acoustic input signal (sound waves) and conversion into an electrical signal, a signal processing unit 120 and a second electroacoustic transducer 130 for converting one of the Signal processing unit 120 output electrical signal into an acoustic output signal.
  • a programmable control unit 140 can optionally be provided, which controls the signal processing unit 120 and contains sequence programs as well as setting parameters for the signal processing unit 120. These programs and parameters serve to adapt the behavior of the signal processing unit 120 (and thus the behavior of the hearing device 100) to different hearing impairments as well as to different hearing situations.
  • signal processing unit 120 and control unit 140 can be combined in a common electronics - not shown.
  • An electrical energy source 150 is used to supply electrical energy.
  • the electronic circuit (s) 120, 140 and the power source 150 are protected by coating and / or potting against the action of liquids.
  • liquids that have entered the hearing aid 100 such as water, can not damage these components 120, 140, 150, since the fluids are retained by the coating and / or potting compound and can not wet the components 120, 140, 150.
  • Open circuit traces connecting the electronic circuitry (s) 120, 140 and the power source 150 are also preferably protected by coating and / or potting against exposure to liquids.
  • an accumulator as the energy source 150 is particularly advantageous when combined with wireless charging devices (not shown) well known in the art.
  • wireless charging devices not shown
  • high-energy batteries whose lifespan should then correspond approximately to the total lifetime of the hearing device 100.
  • a water-resistant embodiment is preferred, i. a structure that can not be damaged due to its construction and / or the materials used by contact with liquids, so that a seal can be omitted.
  • materials which convert a change in shape into an electrical and / or magnetic field and / or an electrical current flow and / or an electrical voltage (and / or vice versa) and which are insensitive to liquids are preferred.
  • Fig. 2 schematically shows a first embodiment of an electroacoustic transducer.
  • a piezoelectret film 220 is applied to a housing portion 210.
  • Piezoelectret films are electrically polarized plastic films (electrets) that contain many flat bubbles 230 in their interior. At the interfaces of these bubbles are polarized charges, so that many small capacitors arise.
  • the compliance of the air (or other gas) in the bubbles is substantially less than the compliance of the film, so that the film is stretchable and compressible in thickness.
  • a voltage can then be tapped off in response to an acoustic signal 250 on the surfaces of the film by means of electrodes 240.
  • a voltage applied to the electrodes 240 causes the thickness of the film to change, so that an acoustic signal can be generated when appropriately controlled.
  • an electroacoustic transducer according to Fig. 2 can advantageously be dispensed with a complicated mechanism and a suitable design on a back volume.
  • an electroacoustic transducer constructed from piezoelectric foil is suitable both as a microphone 110 and as a receiver 130.
  • a film converter does not provide components that can be attacked by (non or weakly corrosive) liquids, so that, after suitable coating of the electrodes, a water-resistant electroacoustic transducer 110, 130 is present, which is not affected by contact with liquids and also can not be damaged and therefore does not have to be sealed. Rather, it is possible, the converter with water or similar. to rinse, and the converter works normally after drying. Even when wet such a converter works, but it can lead to frequency distortion and efficiency losses. Even against mechanical stresses such a transducer is largely insensitive.
  • electroacoustic transducers 110, 130 and classical piezoelectric transducers can be used, the Although they are also water resistant, but have the disadvantage that they work less efficiently and at the same time have a higher sensitivity to mechanical stress and structure-borne noise. Examples of such piezoelectric transducers are bending vibrators and thickness oscillators.
  • Microphone 110 constructed using piezoelectret film also has the advantage, in addition to the insensitivity to water already described in detail, that it is insensitive to structure-borne noise. Compared to conventional microphones may have a larger area may be provided to achieve sufficient acoustic sensitivity.
  • piezoelectric bending oscillators are used as microphone 110, it may be advantageous to provide two spaced microphones of this type in order to be able to compensate for the impact of structure-borne noise on the microphones and to isolate the airborne sound as the signal of interest.
  • a hot wire microphone is used as the microphone 110.
  • Hot-wire microphones do not detect air vibrations but air flow over one or more heated wires by measuring the resistance change of the wire or wires resulting from the cooling effect of the more or less strong air flow, the magnitude of the air flow in turn being dependent on the incoming sound waves , Also, such a microphone in principle well suited for use in conjunction with a hearing aid. The over other types of microphone higher energy consumption (especially for heating the wire or the wires) does not matter if the hearing aid is powered by a wirelessly rechargeable battery, because it can then be conveniently charged, for example, at night.
  • Hot-wire microphones also suffer no damage from contact with water, but fail as long as the contact with water stops. Once the water has drained, the hot-wire microphone will work normally again. Therefore, hot-wire microphones can also be cleaned well.
  • the housing (not shown) of a microphone 110 preferably has two openings, in order to achieve that the microphone 110 is easily rinsed through and easily dries again after - desirable or undesirable - liquid contact.
  • a microphone with such a housing has a directional characteristic, which can be advantageously exploited by appropriate design of the housing for the preferably detection of acoustic signals from a preferred direction.
  • Fig. 3 shows a schematic representation of an embodiment of an electroacoustic transducer based on a piezoelectric foil for use as a handset 130 of a hearing aid.
  • the transducer comprises a piezoelectric film which has substantially the shape of a hollow cylinder segment and which is held in this form either by a housing (not shown) or by its own mechanical properties.
  • Terminals 320 are used to feed electrical signals, which are then converted by the film listener into acoustic signals.
  • Such a handset is primarily for use in the ear canal of the hearing aid wearer.
