Definitions
- the acoustic transducer receives its input signal from an infrared receiver.
- the modulated for sound reproduction signals are here irradiated via IR radiation from outside the ear into the outer ear, where the IR receiver is located with the speaker for acoustic coupling to the eardrum.
- US 7,867,160 B2 describes a variant of this hearing aid, in which an adapted to the shape of the outer ear supply module signals transmitted by means of light to the hearing aid, which sits on the outside of the eardrum.
- the hearing aid has a voltage applied to the umbo support structure and a bimorph structure, which serves the pointwise excitation of the eardrum.
- a microphone in the ear canal has the eminently important advantage of so-called open supply, the directional information, which results inter alia from the individual head-related amplitude transfer function of the sound to maintain unadulterated.
- a frequency-dependent sound damping element is provided to prevent disturbing feedback whistling at higher frequencies. This measure is to allow a hearing impression as in an open auditory canal, although the ear canal is closed by the hearing aid.
- the sound-damping element can be designed as an acoustic diaphragm which has cascaded lamellae arranged one behind the other in several planes and twisted relative to one another in the circumferential direction.
- the present invention seeks to further develop the aforementioned hearing aid so that it allows a better, preferably a low-feedback stimulation of the eardrum.
- the actuator has a tympanic associated inner surface and the ear canal associated outer surface and on the one hand as a flat disc actuator, preferably designed as a piezo disc actuator, the deformation of the eardrum by flat Deformation stimulated, or on the other hand on the actuator at a distance from the outer surface of a diaphragm, preferably a curved diaphragm is arranged, which defines a preferably lenticular cavity with the outer surface.
- the stimulation of the eardrum takes place according to the invention not via vibration of a self-deformable actuator but by planar "in-itself" - deformation of the eardrum by means of a surface deformable actuator.
- the actuator is adapted to be mounted flat on the side facing the ear canal of the eardrum, preferably by means of adhesion forces.
- the diaphragm may consist of a rigid material, and be formed flat or curved.
- the diaphragm can additionally serve as a carrier for microelectronic elements and circuits, and preferably carry a chip battery, which serves the electrical supply of the circuits.
- the advantage here is that the power supply of the hearing aid is wireless, wherein the optical transmission of energy provides the further advantage that the energy losses are low, because light rays can also be directed in the ear canal directed to the receiver.
- the light beams can be introduced into the auditory canal via optical fibers or generated in a supply module arranged in the auditory canal, which under certain circumstances can also be removed and replaced by the patient himself.
- the microphone unit may comprise one or more Elekretmikrophone that can be produced in the required small dimensions with sufficient sound quality.
- the supply module is used here to supply the hearing aid with electrical energy and is preferably used even in the ear canal, on the inner shape of which it is adapted. But it can also be arranged behind the ear, in which case the light radiation is conducted via optical fibers into the ear canal.
- the basilar membrane When the oval window 17 is actuated acoustically via the ossicles 16, the basilar membrane is correspondingly offset and this vibrates by the movement of the fluid in the cochlea 15.
- the displacement of the basilar membrane stimulates hair cells (sensory cells) in a special structure on the basilar membrane (not shown). Movements of these sensory hairs produce electrical discharges into fibers of the auditory nerve 19 through the mediation of spiral ganglion cells positioned in the modiolus or modiolar wall.
- the microphone unit 29 is embodied as an electret microphone and comprises a microphone converter 57 arranged on the outside 56, which converts vibrations of a diaphragm 58 caused by the acoustic signals 28 into electrical signals.
- the array 33 of optoelectronic sensors 34 is arranged on the membrane 58. In this way, the entire surface of the diaphragm 58 stands both for Recording of the acoustic signals 28 as well as for the reception of the light beams 35 available, which not only ensures high sensitivity of the electret microphone but also for a position insensitivity of the optical energy transmission path 27.
