Definitions

  • the present invention relates to an electroacoustic transducer for sound generation and / or amplification for the ear, the transducer being implanted in a bone close to the ear and having a sound entry channel which extends from the auditory canal to the implanted transducer.
  • an electroacoustic transducer of this type for sound amplification for the ear is known.
  • the sound enters a hearing aid via a sound entry channel.
  • the sound is converted into an electrical signal and fed to a piezoelectric crystal.
  • the vibrations are transmitted to the oval window or possibly also to the ossicles or the stirrups via a rod connected to the piezoelectric crystal.
  • the sound does not reach the tympanic membrane or directly to the labyrinth block or the cochlea by structure-borne noise, so that in the latter cases, the poorly sound-conducting aqueous environment of the hose system or the snail causes the formwork cable.
  • the transmission with the known arrangement is therefore insecure and indirect due to the sonication of only parts of the ossicles or the oval window.
  • hearing aids for sound conversion and / or amplification for the ear
  • Hearing aids of this type have a microphone for recording the acoustic energy and for converting them into electrical signals, which are amplified in an amplifier and then converted back into sound signals, so that the sound events can be raised to a higher sound level and can therefore still be heard by the hearing impaired.
  • One type of this hearing aid is the pocket hearing aid, in which the listener is connected to the actual device and the supply unit, for example a battery or a rechargeable accumulator, via a flexible line. The listener is inserted into the ear.
  • Such pocket hearing aids are cosmetically unsatisfactory, since the connecting line between the earphone plugged into the ear and the device which the user wears on the body in the outer clothing is visible to everyone. In addition, it is inconvenient and inconvenient for the user to move the handset with the connecting line from a pocket of the outer clothing to the ear, and this every time he dresses.
  • head hearing aids are also known, in which all the components are accommodated in a single housing. These head hearing aids are worn behind the ear as so-called behind-the-ear hearing aids, in the arms of glasses as so-called hearing glasses or in the ear cup and in the external auditory canal as so-called in-the-ear hearing aids (US Pat. No. 3,764,748). Although these embodiments of hearing aids have a more compact structure, they remain unsatisfactory for cosmetic reasons. With none of these devices, it is possible to hide that a hearing aid is worn or used, since the devices are still visible and stand out despite all efforts.
  • the invention is therefore based on the object of creating an electroacoustic transducer for sound generation and / or amplification for the ear, which is not for third parties is visible.
  • this object is achieved according to the invention by a sound outlet channel which extends from the implanted transducer through the auditory canal wall into the auditory canal.
  • the sound thus arrives from the auditory canal via the sound entry channel to the implanted transducer, is amplified there and conducted as an acoustic sound wave via the sound exit channel back into the ear canal and onto the eardrum.
  • the sound amplification in this embodiment according to the invention is conservative insofar as the amplified sound reaches the eardrum, but no hearing aid devices or entry or exit openings are visible from the outside.
  • the bone transmission vibrator is mounted on the labyrinth block or on the bony outer shell of the cochlea.
  • the sound not only reaches Dis to a link in the ossicular chain or the oval window, but also directly to the labyrinth block or the ear auger by means of structure-borne noise transmission, so that the aqueous environment of the tube system or the auger is acoustically suppressed , and the vibrations act directly on the cells in the wall and / or membrane of the cochlea or the labyrinth block. This makes transmission much safer and more direct.
  • the conversion of the possibly amplified electrical signals in this case does not take place into acoustic waves which are transmitted via the air, but into vibrations which are transmitted by the bone transmission vibrator and as structure-borne noise be propagated. It is particularly advantageous to mount the bone transfer vibrator directly on the labyrinth block. An alternative option is to attach the bone transmission vibrator to the bony outer shell of the screw. In this way an optimal transmission of the sound is achieved. This embodiment of the invention is particularly advantageous also because it reliably avoids acoustic feedback, which is expressed by strong whistling.
  • the transducer is preferably implanted in the bone behind the auricle, the so-called mastoid bone.
  • the implanted transducer can be connected via an electrical line to a power supply unit arranged outside the bone.
  • the power supply unit can be, for example, a battery or an accumulator that is rechargeable.
  • the power supply unit is also implanted at one point on the head or body and is therefore arranged so that it is invisible to third parties.
  • Batteries and accumulators nowadays have such small dimensions that they can be implanted under the skin, for example near the ear, somewhat above the hairline.
  • the power supply unit is implanted in the bone together with the transducer.
  • the power supply unit and the converter are preferably a unitary component, so that the implantation of this component also includes the implantation of the power supply unit.
  • the transducer has a connection piece which projects outwards from the implanted transducer through the bone.
  • This neck or extension can, for example, still protrude somewhat from the skin in the area of the auricle, for example under the hairline.
  • the converter can be adjusted or adjusted via the nozzle.
  • a corresponding button can be provided on the outer end of the connecting piece.
  • the adjustment can a volume setting but also include other setting options, such as a sound aperture setting for changing the sound characteristics and / or the switching on and off.
  • the line connecting the tandler to the supply unit can be guided over or through this connector.
  • a particularly advantageous embodiment of the invention consists in the fact that the supply unit implanted together with the transducer can be charged and that the charging takes place via the nozzle.
  • a rechargeable supply unit which contains, for example, an accumulator, is normally sufficient for 24 to 48 hour operation. Charging can be carried out by means of a charging device via the nozzle, either during sleep or in the evening while reading or watching TV.
  • a very advantageous embodiment of the electroacoustic transducer according to the invention is that the transducer is an electrical receiver that receives electrical signals and converts the electrical signals into acoustic signals.
  • High-frequency receivers for example radio receivers, etc., are preferably used here.
  • the use of the electroacoustic transducer according to the invention as an electrical receiver is, for example, very advantageous for teaching and addressing the hearing impaired without the need for an electrical connection. Again, it is ensured that the electrical receiver is completely invisible due to the implantation.
  • the electroacoustic transducer designed in this way as an electrical receiver can, however, also be used for a wide variety of other tasks, for example for controlling and informing people, without third parties becoming aware of this.
  • the receiving antenna of the electrical receiver is implanted in the bone together with the latter.
  • An alternative possibility is to arrange the receiving antenna in the socket. It is also possible for the receiving antenna to protrude outward through the connector if this should be necessary for the reception conditions.
  • a particularly advantageous embodiment consists in that the receiving antenna projecting outward through the connecting piece is connected to a spectacle frame.
  • the spectacle frame can be made of a metal and at the same time serve as part of the receiving antenna, so that the reception properties of the antenna can thereby be improved without the receiving antenna itself appearing.
  • the electroacoustic transducer is a so-called tinnitus masker.
  • Such maskers are devices that are worn like hearing aids and produce a sound. These maskers are used in people who suffer from ear noises (tinnitus). Such maskers overlay the subjectively heard noises with background music or a background tone, which have humming, sounding, rushing, whistling and hissing sound character and can also be very complex. Through the sound production of the masker, these noises are "masked", since such tones are perceived more pleasantly than the ear noise itself.
  • the possibility of adjusting and adjusting the masker with regard to volume, sound character composition, frequency, etc., via the nozzle means that it can be adjusted at any time and can be adjusted of the generated tones possible.
  • the power supply unit it is possible to mount the power supply unit on a part of the skin behind the ear cup so that it can be reached and replaced at any time from the outside without the need for a surgical intervention, however small, to replace the unit . Since the unit is located behind the pinna and is extremely small these days, it is also not visible to outsiders.
  • the transducer is arranged directly under the skin on the bone. This is also advantageously done behind the ear. Due to the progress of microelectronics today, the transducers can be made so small that they can practically be attached and attached to the bone as thin disks under the skin.
  • the figure shows a partial cross section through the human ear.
  • the ear canal 2 leads from the auricle 1 to the eardrum 3.
  • Above the ear canal 2 is the cranial bone 4, the area adjacent to the ear canal 2 of which is the so-called mastoid 5.
  • a neck 8 protrudes outward through the cranial bone 4 and ends behind the auricle 1 directly on the scalp.
  • At the outer end of the connector 8 there may be a button 9 for adjusting the amplifier.
  • a sound entry channel 10 is provided, which extends from the sound entry opening 11 to a microphone of the hearing amplification device 7. Through this sound entry channel 10, the sound reaches the microphone, where it is converted into an electrical signal, which is amplified in an amplifier circuit of the hearing amplification device 7. The amplified signal is then converted into a sound signal and reaches the ear canal and the eardrum 3 via a sound exit channel 12.
  • the entire hearing enhancement device 7 is implanted completely invisibly in a bone area of the cranial bone.
  • the sound inlet duct 10 and the sound inlet opening 11 are not visible from the outside, and neither is the sound outlet duct 12, so that the entire system does not appear in any way.
  • the neck 8 only protrudes behind the ear, but is covered by the pinna 1 and may lie under the hairline.
  • the sound outlet channel 12 is of course unnecessary.
  • a modification and additional embodiment of the invention further consists in providing a transducer 15 which is attached directly under the skin to the bone.
  • a further embodiment consists in carrying a transducer 16 on a skin area located behind the auricle 1, which can be connected to vibrators by a cable 17 which passes through the skin.

Abstract

Un transducteur électro-acoustique, par exemple un appareil pour sourds ou un récepteur de signaux de haute fréquence, se loge entièrement dans une cavité chirurgicalement ménagée dans les os adjacents à l'oreille, ce qui fait que l'appareil est complètement invisible. De préférence, un accumulateur rechargeable est implanté en même temps que le transducteur électro-acoustique. Le transducteur peut comprendre un tube au moyen duquel il peut régler l'amplificateur, effectuer d'autres réglages éventuels ou charger l'unité d'alimentation, par exemple.
