Definitions

  • the present invention relates to a hearing aid with a housing which is formed substantially cylindrical, and a listener, which is housed in the housing.
  • the present invention relates to a so-called in-the-ear hearing device or a completely in the auditory canal portable CIC hearing aid.
  • Hearing aids are portable hearing aids that are used to care for the hearing impaired.
  • different types of hearing aids such as behind-the-ear hearing aids (BTE) and in-the-ear hearing aids (ITO), e.g. also Concha hearing aids or canal hearing aids (CIC), provided.
  • BTE behind-the-ear hearing aids
  • ITO in-the-ear hearing aids
  • CIC canal hearing aids
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually integrated in a signal processing unit. This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid. In a hearing aid housing 1 for carrying behind the ear, one or more microphones 2 for receiving the sound from the environment are installed.
  • a signal processing unit 3 which is also integrated into the hearing aid housing 1, processes the microphone signals and amplifies them she.
  • the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
  • the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
  • the power supply of the hearing device and in particular of the signal processing unit 3 is carried out by a likewise integrated into the hearing aid housing 1 battery. 5
  • hearing aids especially those of ITE hearing aids and CIC hearing aids, must meet certain compromises.
  • the internal components are to be joined together so that certain requirements for size and shape of the hearing aid are met.
  • the design is dictated by the arrangement of the components, while also meeting certain acoustic, electromagnetic and mounting criteria. This creates voids between the components that can not be used and thus wasted. This leads to larger devices than it would be necessary. Even very sophisticated designs and orientations of the individual components could not usually prevent unused space remained in the respective hearing aid.
  • the object of the present invention is therefore to further reduce the size of a hearing aid and make better use of the space available.
  • a hearing aid with a housing which is substantially cylindrical, and a receiver, which is housed in the housing, wherein the listener is cylindrical and the inner diameter of the housing and the outer diameter of the listener are adapted to each other ,
  • the cylindrical receiver it is possible by the cylindrical receiver, the space of a cylindrical housing better to use. Consequently, a total of a hearing aid can be made correspondingly smaller.
  • the hearing aid in the housing has a cylindrical battery, wherein the handset and the battery have the same outer diameter and are arranged axially one behind the other.
  • the hearing aid may have a cylindrical microphone, which has the same outer diameter as the listener, wherein the two components are also arranged axially one behind the other.
  • the same design and arrangement principle can be used for an amplifier board, so that therefore has a circular amplifier board the same outer diameter as the handset and both are arranged axially one behind the other. In this way, a structure corresponding to a pill tube can be realized in which cylindrical pills are arranged in a space-saving manner one behind the other.
  • Such an arrangement of components is also known under the keyword “Tessellate” and causes unused space is avoided, whereby the device is smaller overall.
  • the following components are arranged in the hearing aid in the order mentioned directly behind each other in the axial direction of the housing: microphone, amplifier board, battery and handset.
  • a very compact hearing aid can thus be constructed in a cylindrical shape.
  • the geometric figures 10, 11 and 12 represent geometric bodies that symbolize components of a hearing aid. They also have a component-specific shape, here a cube 10, a cylinder 11 and a ball 12. The components are to be arranged as skillfully as possible in accordance with acoustic and electromagnetic specifications while complying with compactness requirements. This creates a built space, which is symbolized by a shell 13. This space inevitably contains various cavities 14.
  • the handset is also cylindrical in shape, as is favorable for the hearing aid housing, practically no space is wasted inside the housing.
  • the hearing device housing as well as the listener itself may be circular-cylindrical or oval-cylindrical.
  • a battery Due to their mode of action, a battery must have a certain size or a certain aspect ratio. This results in certain aspects of the hearing aid industry regarding the size and shape of hearing aids. Other components of a hearing aid, however, can easily take on a different shape. This shape can usually also change. Since hearing aids should now be made as small as possible, it is now possible, according to an embodiment of the present invention, to try the individual components of the hearing aid with regard to FIG. 3 to shape and arrange. If the battery is regarded as a constant with its cylindrical shape, then it is favorable to design the other components likewise cylindrical with the same diameter as the battery and to arrange them axially one behind the other. Such an arrangement is in FIG. 4 shown in the side view.
  • a battery 20 On both end faces of a battery 20 is another cylindrical component, in the example of FIG. 4 a cylindrical microphone 21 on one side and a cylindrical receiver 22 on the other side.
  • these components or this arrangement are reproduced in a perspective view.
  • the battery 20 thus has the typical button cell shape here.
  • the other two components, namely the microphone 21 and the handset 22 have the same outer diameter as the battery 20.
  • the axial dimension is set for each component according to the needs. Since now all components 20 to 22 coaxial are arranged one behind the other, results in a total of a more or less long cylinder.
  • FIG. 6 a CIC hearing aid is shown in partial section. It contains the in the FIGS. 4 and 5 already presented cylindrical components: battery 20, microphone 21 and receiver 22. Between the battery 20 and the microphone 21 is here also a cylindrically shaped amplifier board 23. This is the sake of clarity in the FIGS. 4 and 5 not shown. After it is also cylindrical, no space is wasted by them.
  • the cylindrical components 20 to 23, which are arranged coaxially, that is, one behind the other, are accurately surrounded by a housing 24. Consequently, this housing 24 also has a cylindrical shape.
  • the housing 24 is in turn surrounded by a soft shell 25, which conforms to the ear canal of the respective user. Overall, this results in a cylindrical hearing aid whose shape comes closest to the tubular ear canal.
  • each component of the hearing device has virtually the same shape as a reduced section of the auditory canal, namely the cylindrical shape, the space in the hearing aid housing can be optimally utilized, so that ultimately the length of the entire hearing device can be reduced to a minimum.
  • the installation space can be reduced to a minimum with skillful axial arrangement of the components.
