Definitions

  • the invention relates to a hearing aid, in particular a so-called “in-the-ear hearing aid” according to the preamble of the main claim.
  • a generic in-the-ear hearing aid is described in DE-GM 84 28 887.
  • the known device is intended to create a device which is cosmetically adapted to the ear, the chambers for receiving the electrical components and / or their closures being intended to be invisible in use and which should have good positional security within the ear.
  • the known device consists entirely of plastic, from which the necessary chambers and channels are formed and has an outwardly projecting volume control.
  • the currently used, colored plastics are used in the known device, whose color characteristics must be addressed as "piggy rose".
  • the color characteristic of this plastic is changed so that the outwardly facing cover layer of these chambers must be so thick that the color stability can be achieved again through this thick layer.
  • volume control protruding outwards can also only be made of a relatively thick plastic, since otherwise the required stability is missing and - nevertheless, the hearing aid supposedly to individually adjust the auricle with its auricle part - the outwardly protruding volume control part continues to disturb the aesthetics and is visible.
  • the invention has for its object to improve the generic device in such a way that the device can be individually adapted to both ear in terms of color and shape, but that a great load-bearing capacity and stability can still be achieved, while maintaining the device is possible, ie all electrical components are accessible at all times so that minor repairs or adjustment measures can be carried out.
  • the invention proposes an in-the-ear hearing device that individually corresponds in terms of color and anatomy to the conditions of the auricle.
  • the hearing aid consists on the one hand of an individually and anatomically adapted precious metal shell, which is characterized by good skin tolerance and comfortable wearing with high stability. With such precious metal shells, any fine adjustments that may become necessary can be made without any problems.
  • the consistency of the precious metal bowl is not affected by sweat and cerumen, is easy to clean and can be manufactured with a relatively low weight.
  • An individually and anatomically adapted plastic earpiece part is embedded in this precious metal shell, preferably a gold shell.
  • This plastic part which is visible from the outside, covers the precious metal shell and consists of an epithesis plastic, the color of which can be adapted exactly to the skin color of the ear.
  • the anatomical course of the cavum conchae is exactly simulated on the outside and the natural skin color of the plastic is also retained by external influences, such as subsequent processing by milling, exposure to light, etc. Part of the required electrical installations is housed in this plastic part on the back.
  • the microphone In the upper part of the auricle part, the microphone is located in the area of the cymba conchae and opens outwards.
  • the microphone is sealed with a light-curing plastic.
  • the microphone's sound inlet is hidden under the helix and crura anthelicis. This storage at this point brings cosmetic advantages and protects against unpleasant wind noises, so that technical advantages are achieved at the same time.
  • the battery is housed in the deepest part of the cavum conchae.
  • a battery chamber flap opens opposite the battery chamber, which in turn adapts to the anatomical shape of the concha.
  • the earpiece is carried by cables from the auricle part and is stored far down in the peg part of the ear canal part and fixed in the precious metal shell with silicone.
  • the amplifier including the necessary logic circuit is located in the pinna part opposite the center of the peg part of the ear canal part.
  • the electronics are sealed with silicone or a light-curing plastic, so that protection against moisture is achieved at the same time.
  • the preferably used sensor-controlled volume control consists of two metal pins, which open at a distance of approx. 2 mm on the top of the ear cuff and end flush with the top.
  • a pair of switching pins is provided to raise or lower the output sound level.
  • the associated transistor is switched through.
  • the sensor for lowering or raising the inverting input of the operational amplifier connected as an integrator is actuated, a voltage which is positive or negative with respect to the non-inverting input is formed. This causes a linear decrease or increase in the integrator output voltage and thus an increase or decrease in the resistance.
  • the frequency response of the hearing aid does not change.
  • the two-part design of the hearing aid makes it easy to maintain.
  • the ear cup part made of epithesis plastic, covers the edges of the precious metal shell, which remains invisible. Because the device according to the invention is constructed in two parts, the actual auditory canal part can be made of a stable material that provides the necessary stability and the ear cup part can be taken into account technical aspects are made from an epithesis plastic.
  • the epithesis plastic is usually not as strong as other plastics.
  • the sensor circuit used has, in addition to the optically advantageous effect, namely that the previously required volume control, usually designed as a knurled wheel, is avoided, the advantage that the hearing aid is also suitable for patients with stiff fingers, that is, gouty fingers, such as those that occur particularly in older people , are easy to adjust in terms of volume.
  • 1 denotes an auditory canal part and 2 an ear cup part which, according to FIG. 1, form the actual hearing aid when inserted into one another.
  • the ear canal part consists of an outwardly concave shell 3, to which a tubular pin part 4 connects, which closes at its mouth sen is, as can be seen from the partial representation in Fig. 1.
  • a closure plate 5 in which two openings 5 and 7 are provided.
  • an opening which can be closed by a battery chamber flap 8.
  • the ear canal part 1 is made of precious metal.
  • precious metal preferably gold
  • the precious metal bowl has the advantage that its consistency cannot be influenced in any way by sweat and cerumen.
  • Fig. 3 the ear cup part 2 is shown seen from the back, while Fig. 1 shows the view of this ear cup part.
  • a battery chamber 9 is formed on the back of the auricle part and communicates via a corresponding conduit 10 with a space which is used to hold a microphone 11.
  • the corresponding lines can be laid in channel 10. After inserting the components, the chambers and the channel can be closed with a light-curing plastic.
  • the back of the auricle part 2 carries an amplifier element 14, which also contains the logic circuit, and on this amplifier element 14 connects via line a receiver 15 which opens into a sound tube 16, which sound tube can be connected to the opening 6 according to FIG. 1.
  • the second opening 7 in the plate 5 of the pin part 4 serves to receive a frequency compensation tube or ventilation tube, which opens at the top of the auricle part 2 in the region of the opening 20 recognizable there.
  • the microphone opening 17 connected to the microphone 11 can be seen in FIG. 1.
  • the microphone opening 17 or the corresponding sound entry opening is concealed beneath the helix and crura anthelicis, so that on the one hand this creates a cosmetically advantageous location for this opening and on the other hand wind noise is prevented.
  • FIG. 1 further shows two pairs of sensor switches 18 and 19. These sensor switching pairs each consist of two sensor pins, when touched an associated transistor is switched through.
  • the sensor 18 or 19 is actuated to lower or raise the inverting input of the operational amplifier connected as an integrator, a voltage which is positive or negative with respect to the non-inverting input is formed. This causes a linear decrease or increase in the integrator output voltage and thus an increase or decrease in the resistance.
  • the two components namely the ear canal part 1 and the ear cup part 2
  • the auricle part 2 is made of epithesis plastic, which can be made very skin-friendly. It is essential that this plastic part only has the task of ensuring the optical and anatomical adaptation on the one hand, and on the other serving as a carrier for part of the electrical components, while the stability and strength of the device is created by the auditory canal part 1, which either consists of Precious metal, preferably gold or made of a corresponding load-bearing plastic. For many reasons, the production from precious metal should be preferred.
  • the two components namely the auditory canal part 1 and the auricle part 2 are also connected to one another by a corresponding, preferably light-curing plastic and thus have the appropriate durability, on the other hand, the two components can be easily detached from one another for repair and maintenance purposes, all of which are electrical Units of the maintenance person are freely accessible.
