Definitions

  • the invention relates to a hearing aid, in particular a hearing aid, comprising a housing, a signal processing unit arranged in the housing and a first sound generator, which is arranged in the housing, wherein the first sound generator is adapted to convert an output signal of the signal processing unit into sound.
  • a hearing aid having a microphone and an electroacoustic transducer
  • mechanical vibrations caused by the electroacoustic transducer can lead to instability of the signal path.
  • the vibrations may be recorded by the microphone through an acoustic feedback and converted into an electrical signal which, after amplification, is applied to the electroacoustic transducer and converted into sound by it.
  • a closed loop is formed, in which the vibrations are amplified more and more.
  • instability of the system which is noticeable in an increase of unwanted signal components that may exceed the load limit of individual components of the hearing aid or the pain threshold of a user of the hearing aid.
  • frequencies between 1 kHz and 12 kHz are particularly affected by the electro-acoustic amplification and resonant feedback of mechanical vibrations.
  • a sufficiently high gain of a signal before the sound generation is particularly important for frequencies between 2 kHz and 4 kHz. Since particularly important formants for the detection of consonants occur in this frequency band, a good reproduction dynamics, ie in particular a very high output level, is of particular importance for speech intelligibility.
  • the hearing aid should therefore allow the loudest possible generation of sound in this frequency band in order to be able to produce as rich a sound image as possible when reproducing speech.
  • the US 2007/291971 A1 refers to a hearing aid in which two different receivers, so speakers, are provided for the generation of high-frequency or low-frequency sound signals.
  • the two speakers are each connected to a high-frequency or a low-frequency output of the D / A Koverters, which lies in the signal path behind the signal processor.
  • the high-frequency speaker either cylindrical with an inner sound conductor (for the low-frequency sound of the underlying low-frequency receiver), or the low-frequency sound laterally in a tubular conductor at high frequency Receiver to pass by.
  • these arrangements lead to a complex design and also to a complex contacting, in particular of the high-frequency receiver.
  • the US 2006/0159298 A1 also mentions a hearing aid in which two receivers are used for sound generation.
  • an output signal of the signal processor of the hearing aid is divided by a frequency-separating analog filter into a high-frequency and a low-frequency component, which are reproduced by one of the two receivers.
  • thermoacoustic transducer for generating a counter-sound signal
  • the counter-sound signal is to be compensated for by a direct to propagate through a vent to the direct sound.
  • the invention is therefore based on the object to provide a hearing aid, which in the generation of sound the highest possible playback dynamics across a wide frequency spectrum allowed, and should have a compact design and the lowest possible susceptibility to mechanical vibration.
  • a hearing aid in particular a hearing aid, comprising a housing, a signal processing unit arranged in the housing, a first sound generator, which is arranged in the housing, and a second sound generator, wherein the first sound generator and the second sound generator each set up are to convert an output signal of the signal processing unit into sound.
  • the hearing aid further comprises a crossover with a signal input, a low-frequency output and a high-frequency output, wherein the signal processing unit for supplying the output signal is connected to the crossover via the signal input, wherein the low-frequency output to the first sound generator and the high-frequency output is connected to the second sound generator, and the first sound generator comprises an electro-acoustic transducer, which generates vibration energy in the sound generation.
  • the second sound generator comprises a thermoacoustic transducer which generates no vibration energy in the sound generation.
  • the invention is based on a hearing device which has a housing, a signal processing unit arranged in the housing, and a sound generator arranged in the housing, which is set up to convert an output signal of the signal processing unit into sound.
  • the sound generator is designed as an electroacoustic transducer.
  • the invention recognizes in a first step that for the highest possible playback dynamics in a wide frequency spectrum, a frequency-dependent attenuation of the signal level to prevent vibration is counterproductive, since the lack of dynamics in the corresponding frequency bands impaired the sound quality, that this is not remedied by other measures can be. It should therefore be attempted to prevent the occurrence of vibrations through design measures and not by regulating the gain.
  • the vibrations to be prevented arise substantially initially as vibrations of the housing surrounding the sound generator, which absorbs, for example, by an insufficiently damped suspension of the sound generator of this vibration energy, which arises in the sound generation, and thereby the housing is excited according to its resonance properties.
  • An improvement in the suspension damping is limited, however, due to space limitations.
  • such an adaptation of the damping in a compact design is sufficiently effective only for certain frequency bands, since on the one hand, the damping effect at a given elasticity of a damper is frequency-dependent, and on the other hand depend on the corresponding attenuation constants of the suspension of the dimension.
  • the suppression of a coupling of generated by the sound generator vibration energy in the surrounding housing is thus under the structural specifications not to achieve arbitrary broadband frequency spectra.
  • a particularly high dynamics in the reproduction of signals is desired in order to achieve a high intelligibility
  • the second sound generator would be interpreted in particular for a high playback performance in this frequency band.
  • the first - that is, the originally existing - sound generator could then be designed, for example, for lower frequency bands, and the suspension of the first sound generator could be designed especially for the attenuation of low-frequency vibrations.
  • the invention proposes that the first sound generator comprises an electroacoustic transducer, and the second sound generator comprises a thermoacoustic transducer. This allows a particularly compact generation of sound in particular higher frequencies with high playback dynamics.
  • thermoacoustic transducer While usually the generation of sound in a hearing aid by electro-acoustic transducers, the use of a thermoacoustic transducer in the second sound generator in this case first has the advantage that it does not generate vibration energy in the generation of sound.
  • a thermoacoustic transducer from an electrical signal a sound signal is generated by the fact that on a surface or a surface of the thermoacoustic transducer by the electrical Signal temperature fluctuations are generated.
  • These rapidly oscillating temperature fluctuations on the surface or surface of the thermoacoustic transducer lead to a time-variable temperature gradient of the adjacent air layers. By this time-varying temperature gradient, the adjacent air layers can be set in vibration, which propagate as a sound signal.
  • thermoacoustic transducer For such a sound generation of any kind of proper movement of the thermoacoustic transducer is not required, and not provided.
  • the sound is generated by the thermoacoustic transducer thus no vibrations, which can be delivered to the environment or to a suspension.
  • a sound generator with a thermoacoustic transducer in particular one which is suitable for an arrangement in a hearing aid because of its dimensions, also has particularly dynamic playback behavior for frequencies above 1 kHz.
  • a low-frequency output is understood to mean an output at which signal components of a signal input into the crossover via the signal input in such a way be issued that decreases from a first cutoff frequency of the signal level up to a second cutoff frequency and from the second cutoff frequency no appreciable signal level is more recorded.
  • a high-frequency output is accordingly defined as an output at which signal components are output which have a significant signal level only above a third limit frequency.
  • the third cutoff frequency is preferably well below the second cutoff frequency and particularly preferably in the range of the first cutoff frequency, so that a sufficient overlap of the frequency responses of the low frequency output and the high frequency output is ensured.
  • the crossover is set up such that the frequency response of the low-frequency output is tuned to the frequency response of the first sound generator, and that the frequency response of the high-frequency output to the frequency response of the second sound generator, so the thermoacoustic transducer is tuned.
  • the use of such a crossover allows the operation of the first sound generator and designed as a thermoacoustic transducer second sound generator with a common output signal of the signal processing unit, whereby only one signal output is required at this.
  • thermoacoustic transducer comprises at least one film formed of carbon nanotubes, which is connected to at least one signal terminal, wherein by applying a signal voltage to the or each signal terminal, a time-varying heating in the or each film is caused, by means of which the thermoacoustic effect a sound is generated.
  • the carbon nanotubes can be aligned substantially parallel to each other, even several layers of bundles of parallel carbon nanotubes, wherein the orientations of the carbon nanotubes of two successive layers are mutually orthogonal, is possible in this case.
  • thermoacoustic transducer with a carbon nanotube film can also be dimensioned particularly compact under the specifications of the desired sound reproduction.
  • the second sound generator is arranged in the housing. Such positioning simplifies the connection of the second sound generator to the signal processing unit.
  • an arrangement of the second sound generator is in principle also possible in a connectable to the hearing aid sound conductor, via which a generated sound signal is continued to the hearing of a user. Such a procedure allows a further reduction in the size of the hearing aid.
  • the first sound generator is designed such that it has a higher maximum reproduction level for frequencies in a frequency range up to 4 kHz, preferably up to 2 kHz, than for frequencies above this frequency range.
  • the maximum playback level must be related to the maximum sound pressure that can be generated.
  • the frequency response of the first sound generator can decrease below a first cutoff frequency below 4 kHz, preferably below 3 kHz, and at a second cutoff frequency, preferably above 4 kHz, in particular above 6 kHz, have a complete cut-off.
  • thermoacoustic transducer in particular one which is suitable for an arrangement in a hearing aid in terms of its dimensioning, is designed especially for the generation of sound of frequencies above 1 kHz, and thereby a maximum reproduction level preferably in the range between 2 kHz and 4 kHz has to show
  • a first sound generator that reaches its maximum playback level in lower frequency bands, in combination with the second sound generator, can contribute to a complete sound image.
  • a sound chamber is formed with a sound outlet in the housing, wherein the first sound generator is adapted to generate sound in the sound space, and wherein the second sound generator is arranged in the sound space.
