Definitions

  • the invention relates to a hearing aid with wireless remote control according to the preamble of claim 1.
  • a hearing aid of this type is known from DE-OS 19 38 381. It is known that hearing aids should be as small as possible so that they can be worn inconspicuously. This has resulted in miniature hearing aids that are worn on the head, particularly those that can be inserted into the ear canal. In this type of device too, at least the volume, but possibly also a number of other functions essential for adapting to different listening situations, should be able to be changed in operation. This requires adjustment devices that are accessible while the device is in operation in contact with the carrier. In addition, the handling area should be clear when setting. This is achieved, for example, with a hearing aid according to DE-OS 19 38 381.
  • the components are distributed over two housings, one of which contains a transmitter that is wirelessly connected to the other, in which the actual hearing aid is located together with a receiver that is tuned to the transmitter.
  • the housing which contains both the hearing aid and the receiver, offers very little volume.
  • the so-called "in-the-ear devices" that are worn in the ear canal rarely have more than 100 mm3 of free space for the installation of a remote control receiver. Therefore, the aim was to get by with a receiver that does not require an additional sensor, antenna or the like.
  • a hearing aid device with remote control is already known from DE-OS 34 31 584, in which the microphone of the hearing aid is also used as the receiving element for the control signals.
  • About Carrying the control signals inaudible sound, especially ultrasound, is used.
  • the ultrasound transmitter is located in a control unit in which the control signals are generated via a keyboard and emitted via a loudspeaker, and in the hearing aid the derivation of the signals picked up by the microphone is split into two branches, one of which is inserted into the hearing aid and the other a filter blocking all signals except the ultrasound signals leads to the control part of the hearing aid.
  • the hearing aid is largely freed from the ballast of actuators and switches.
  • the main functions of the remote control are as follows: After pressing an operating button, the transmitter electronics recognizes this process and the control signal is coded and transmitted according to the desired function. The inverse process takes place in the receiver. The signal is received, decoded, recognized and the electronic control element is actuated.
  • the electromagnetic transmission, the infrared and the ultrasound transmission described above have already been proposed (DE-PS 24 07 726).
  • each of the transmission paths can be influenced by specific sources of interference.
  • electromagnetic transmission a variety of electromagnetic interference sources must be taken into account.
  • free choice of transmission frequencies is very limited by country-specific postal regulations and varies greatly from country to country.
  • infrared transmission direct sunlight on the receiver diode can cause problems and the receiver diode must be attached to an exposed location on the hearing aid.
  • the ultrasonic path can be disturbed by high-frequency sound sources, such as an ultrasonic cleaning bath.
  • Additional components are required for electromagnetic transmission and infrared transmission, while the existing microphone can be used for ultrasound transmission.
  • the invention has for its object to provide a hearing aid (especially in-the-ear hearing aids, implanted hearing aids for magnetic or mechanical excitation of the middle ear) with wireless remote control, which is improved with regard to the transmission of the control signals and enables a more inconspicuous use of the remote control.
  • a hearing aid especially in-the-ear hearing aids, implanted hearing aids for magnetic or mechanical excitation of the middle ear
  • sound outside the hearing range
  • this is caused by bone sound excitation on the skeleton, in particular the skull bone of the hearing aid wearer and not, as in the known designs, transmitted to the outer ear by airborne sound transmission.
  • a suitable design of the remote control transmitter ensures that the remote control is possible completely inconspicuously, namely by the hearing aid wearer holding the small control device in his hand and executing movements for transcutaneous contact of the control device contact area with his bone structure.
  • the hearing aid according to the invention works with sound waves, in particular in the ultrasound or also in the low-frequency range outside the hearing range, which are emitted by the vibrator of the remote control device in such a way that when the control device is hung up, e.g. stimulate the skull bones to vibrate on the scalp, over the rock or temporal bone. These vibrations are transmitted to the hearing aid inserted in the ear canal and to a sound transducer present in the hearing aid, which converts them into an electrical signal. The decoding of this signal gives the control signal for setting the hearing aid functions.
  • the control device 1 provided for remote control of the hearing aid devices shown in FIGS. 3 to 5 is a handy, small, battery-operated device in the embodiment according to FIGS. 1 and 2, the housing of which can be designed ergonomically.
  • the control unit has, for example, an operating panel 2 with sensor buttons 3.
  • the control unit contains a coding circuit 4, which generates a serial sequence of data and test bits in accordance with the programming or control command effected by touching the sensor buttons 3 and which repeatedly transmits to a modulator 6 at the transmission clock frequency determined by the frequency of a clock generator 5 until a timing circuit also fed by the clock generator 5 ends the transmission and switches the control unit back to the ready state.
  • the serial information received from the coding circuit 4 of the oscillation generated in a generator 7 is modulated and shifted into a carrier frequency range which can be transmitted inaudibly or at least not disturbingly acoustically to the human skeleton. An audible airborne sound emission into the room is excluded in any case.
  • the modulator 6 is an end amplifier 8, which raises the output signal to a power level sufficient for reprogramming the hearing aid, and a vibrator 9 with a contact surface 10, which is used for transcutaneous coupling of the programming or control signal emanating from the vibrator to the bony skeleton of the hearing aid wearer.
  • the selection of the operating function by means of the sensor buttons 3 can take place before the control device 1 is placed on the skin in order to carry out the remote control as inconspicuously as possible. While switching to the body surface, the actuation of switching elements is not absolutely necessary, but is still possible.
  • a simple variant consists in letting the transmitter work for a fixed time (e.g. 5 seconds) after removing the fingers from the control element or the sensor keys and then switching it off.
  • control device 1 remains active as long as the contact surface 10 of the vibrator 9 is in contact with the skin.
  • control device can be switched on and off by sensor strips on the contact surface 10 or by movable mounting of the vibrator 9 in connection with a microswitch.
  • This form of sequence control also minimizes the energy consumption of the control unit.
  • FIG. 2 shows an embodiment of the housing design of the control device 1 as a flat control device which is adapted to the shape of the hollow hand and has a non-slip coating on the back (facing the hand).
  • the control device hidden in the slightly curved hand, can be guided inconspicuously, for example, to the head.
  • the grip and the actuation of the control device with one hand favor a recessed grip 11.
  • a switch that can be actuated by a wheel 12 can be used, for example serve, which is indicated in Figure 2 under the thumb on the control device and strengthens the function (eg volume) when moving in the direction of the thumb tip, decreases the function when moving in the direction of the thumb root.
  • This switch or its actuating wheel 12 preferably assumes a neutral central position when the load is released. If this switch 12 is not required for a simple switchover function (eg microphone off, hearing coil for telephone operation on), it remains inoperative.
  • an in-the-ear hearing aid is used which has a housing shell 26 which is adapted to the ear canal and in which a microphone 27 for converting the speech sound signals into electrical signals is arranged such that the microphone 27 is decoupled from the housing 26 in relation to structure-borne noise excitation .
  • a second sound transducer 28 is provided in the housing 26 of the in-the-ear hearing device, but in such a way that the sound transducer 28 is coupled to the housing shell for the purpose of structure-borne sound excitation and can receive the signals transmitted by structure-borne sound for controlling and programming the hearing aid device and convert them into electrical control commands .
  • the receiver 29 of the hearing aid device is designated by 29, which receives the electrical signals emitted by the microphone 27 and amplified and reshaped in an amplifier circuit 30 (for example filtered and / or reduced in dynamics), converts them into sound vibrations and emits them in the direction of the eardrum 15.
  • Contact springs 32 are provided for contacting a circuit board of the amplifier circuit 30 with a battery 31.
  • the sound transducer 28 built into the hearing aid can be a microphone specially developed for the transmission frequencies and mechanically well coupled to the housing wall of the hearing aid, which microphone is present in addition to the normal microphone 27 which receives the speech signals.
  • the sound transducer provided for the speech signals is used, i.e. the microphone 33, at the same time as a sound transducer for the structure-borne sound signals for remote control of the hearing aid.
  • the remote control signals are separated from the speech signals by a frequency-selective circuit known per se, e.g. using high and low pass filters.
  • the sound transducer 33 is mounted in a plastic pocket 34, which causes a high attenuation in the listening area, but as low as possible at the carrier frequencies of the remote control signals.
  • the sound transducer 33 is supported by the plastic part 34 on the housing shell 26 and at the same time embedded in plastic.
  • the hearing aid With this hearing aid with a magnetically excitable middle ear implant formed by a permanent magnet 36, the hearing aid itself can be removed from the auditory canal 14 without intervention.
  • the permanent magnet 36 which e.g. is attached to the stirrup 18 of the ear by a screw or adhesive connection, serves an excitation coil 35 which is arranged in the housing shell 26 of the hearing aid and is connected to the amplifier circuit 30.
  • the excitation coil 35 is fed with the amplified electrical output signal of the circuit 30 and this signal is transmitted in the form of an alternating magnetic field to the small permanent magnet 36 attached to the stirrup 18.
  • the permanent magnet set in vibration transmits the speech sound signals to the inner ear.
  • the middle ear is opened and the anvil of the ear removed.
  • the fully implantable hearing aid according to FIG. 5 consists of a liquid-tight and gas-tight housing 40 of an amplifier part 41 made of tissue-compatible material, which is used for fixation, but especially for structure-borne sound transmission by means of a screw 50 or the like. is attached to the skull 42. Furthermore, a microphone 43 is implanted in the area of the auditory canal 14, which is the through the ear canal guided speech sound signals and in the form of electrical signals via an electrical line 44 to the input of the amplifier part 41.
  • a piezoelectric vibrator 45 is attached to the skull bone in such a way that the free end 46 of the vibrator 45 causes the stirrup 18 to vibrate as soon as it deforms under the influence of the electrical alternating voltage transmitted from the output of the amplifier part 41 via an electrical line 47.
  • the anvil and hammer are removed for the implantation of the vibrator 45.
  • the circuit board with integrated and discrete components of the amplifier part 41 is supplied from a connected battery 49.
  • the amplifier part 41 containing the battery 49 can also be fully implanted because of the low power consumption.
  • the amplifier part 41 is screwed to the cranial bone 42 and a structure-borne sound microphone 48 (structure-borne sound vibration sensor) is brought into mechanical contact, for example via a connecting web 51, with the screw 50.
  • a structure-borne sound microphone 48 structure-borne sound vibration sensor
