Definitions

  • the present invention is related to a method for manufacturing a hearing device according to the pre-amble of claim 1 as well as to a hearing device.
  • the present invention is firstly directed to a method for manufacturing a hearing device at least comprising one acoustic transducer in a housing.
  • the method according to the present invention comprises the steps of: - selecting the at least one acoustic transducer to be inserted into the housing,
  • the present invention has the advantage that the transmission of vibrations are dramatically reduced, if the connecting points between the acoustic transducer and the housing are limited to low vibrating areas.
  • the step of positioning the at least one acoustic transducer is performed by fixing the at least one acoustic transducer at positions, at which the vibration pattern is minimal.
  • the method further comprises the step of providing supporting elements inside the housing for fixing the at least one acoustic transducer at positions, at which the vibration pattern is minimal.
  • Supporting elements can be placed in the design step of the shell taking into account the vibration pattern.
  • the method further comprises the step of limiting contacts of the supporting elements to low vibrating areas of the at least one acoustic transducer.
  • the method further comprises the step of providing a transducer pocket in the housing for holding the at least one acoustic transducer.
  • Providing a transducer pocket is in particular advantageous when a standard acoustic transducer is inserted in the housing because the transducer pocket can be fixed at arbitrary positions to the housing while the transducer pocket is already adapted to the individual vibration pattern. Therefore, the insertion or positioning of the acoustic transducer can be performed very quickly.
  • the pocket is designed for holding standardized acoustic transducers .
  • the supporting elements are made of rubber or silicon.
  • This material can be stretched and is able to damp residual vibrations still present at the suspension position.
  • the at least one acoustic transducer can be applied to a microphone or a receiver.
  • housing is a shell that is matched to an auditory canal of a hearing device user.
  • the present invention is directed to a hearing device that comprises at least one acoustic transducer contained in a housing, wherein contact points are provided between the housing and the acoustic transducer for holding the acoustic transducer in its position.
  • the contact points are arranged at minimum vibration areas of the acoustic transducer, the minimum vibration areas having been determined via a vibration pattern of the acoustic transducer.
  • the supporting elements are arranged at the contact points, the supporting elements being a part of the housing.
  • a transducer pocket is provided to hold the acoustic transducer in its position in the housing.
  • the supporting elements are made of silicon or rubber.
  • the at least one acoustic transducer is one or a combination of both of the following components: - microphone; - receiver.
  • an outer surface of the housing is matched to an auditory canal of a user.
  • Fig. 1 schematically shows a cross-section of a part of a first embodiment of an inventive hearing device comprising a receiver
  • Fig. 2 schematically shows a cross-section of another part of an embodiment of an inventive hearing device comprising supporting elements for a microphone
  • Fig. 3 schematically shows a cross-section of the same part of an inventive hearing device, but with other supporting elements for the microphone.
  • the present invention is directed to a method for manufacturing a hearing device.
  • a part of the hearing device namely the tip pointing to the inner ear while the hearing device is inserted into a user's ear, is depicted in Fig. 1, which shows a shell 1 matched to the auditory canal of the hearing device user.
  • an acoustic transducer 2 such as a receiver, is contained having a nipple 6 that is operatively connected to an outlet 5 extending through the shell 1.
  • supporting elements 3 and 4 in the form of protrusions are provided in the shell 1 in order to prevent the acoustic transducer 2 from moving within the shell 1.
  • the positioning of the supporting elements 3 and 4 are chosen in such a manner that a transmission of vibrations from the shell 1 to the acoustic transducer 2 - and vice versa - is minimal. Therefore, a vibration pattern of the acoustic transducer 2 is determined. Once the vibration pattern of the acoustic transducer 2 is determined, the acoustic transducer 2 is positioned in the shell 1 in such a manner that mechanical connections between the shell 1 and the acoustic transducer 2 are limited to areas, in which no or only little vibration is expected.
  • the advantage is obtained that vibrations are not transmitted, or the transmission of vibration is at least reduced, resulting in an improved feedback behavior of the hearing device.
  • vibrations were not transmitted, or the transmission of vibration is at least reduced, resulting in an improved feedback behavior of the hearing device.
  • a 15 dB improvement of vibrations has been obtained compared to known hearing devices, i.e. vibrations could have been considerably reduced so that higher gain are now possible without provoking feedback in the hearing device.
  • the inner cavity of the shell 1 is modified in order to provide a transducer pocket, in which the acoustic transducer 2 is supported and suspended at specific location.
  • the present invention proposes a limited connection between the shell 1 and the acoustic transducer 2 based on the vibration pattern. The connections are reduced to the outlet 5 and to some contact points (supporting elements 3, 4; protrusions) positioned at the low vibrating area of the acoustic transducer 2.
  • the supporting elements 3 and 4, or suspension points are made of rubber or silicone to reduce the vibration transmission.
  • the present invention comprises an intelligent placement of the transducer pocket for a minimal vibration transmission (according to the vibration pattern of the receiver) and for an easy insertion of the acoustic transducer in the shell 1 (insertion path verification) .
  • Fig. 2 schematically shows a cross-section of another embodiment of an inventive hearing device.
  • a transducer is again being referred to by reference sign 2 indicating a microphone, for example, arranged to pick-up sound entering via an opening 10 in the shell 1.
  • the transducer 2 is again supported by supporting elements 7, 8 and 9.
  • a vibration pattern of the acoustic transducer 2 - here the microphone - is determined. Once the vibration pattern of the acoustic transducer 2 is known, the acoustic transducer 2 is positioned in the shell 1 in such a manner that mechanical connections between the shell 1 and the acoustic transducer 2 are limited to areas, in which no or only little vibration is expected.
  • Fig. 3 shows the same section as in Fig. 2, but with a supporting element 7 which is different to the one shown in Fig. 2.
  • the supporting element 7 encloses the transducer 2 at an end section which is positioned opposite to the opening 10 in the shell 1.
  • transducer pocket is provided which prevents the transducer 2 from moving within the shell 1.
  • Fig. 1 shows a receiver as transducer 2 being supported according to the present invention
  • the embodiment of Figs. 2 and 3 show a microphone as transducer 2
  • a further embodiment of the present invention is directed to a combination of the two embodiments described in connection with Figs. 1 to 3.
  • an overall improvement results by supporting all transducers that are present within a hearing device housing.
  • all transducers 2 being susceptible to acoustic inferences contribute to the improved feedback behavior resulting in a particularly advantageous hearing device.
  • the present invention is not limited to be applied to an ITE- (in-the-ear) or ITC- (in-the-canal) hearing device but can also very well be applied to a so called BTE- (behind-the-ear) hearing device.
  • the present invention can very well be applied to any type of hearing device housing.
