Definitions

  • the present invention relates to a microphone protection according to the preamble of claim 1 and a hearing aid resp. Hearing aid according to the preamble of claim 13.
  • hearing aids have at least one microphone.
  • This microphone is exposed to various environmental influences, such as moisture, sweat and cerumen.
  • controls such as switches or volume control are also located in close proximity to the microphone.
  • dirt in the form of particles can be deposited by the fingers of the hearing aid wearer in the area of the microphone opening. This leads to blockages of these openings and thus at least to a deterioration or even Verunliniung the sound-recording capacity of the microphone.
  • the hearing aids concerned must then be cleaned or the microphone must be replaced, which is usually only by appropriately trained resp. trained professionals can be performed and incurs additional costs. This deterioration or failure of microphones is perceived as a reduced quality of the entire hearing aid, which is reflected in a correspondingly poor image of the affected device.
  • a number of devices are known for the protection of hearing aid microphones. So are many hearing aids the protective covers of the microphone openings firmly in the battery cover or the faceplate resp. Module integrated or glued. Therefore, they must be cleaned in a complex manner when contaminated.
  • the object of the present invention was to find a cover for openings in hearing aids, which are easy to assemble, provide reliable protection against dirt, and also easy to clean or replace if necessary.
  • the microphone protection for hearing aids for at least partial covering of arranged on the outside of the hearing aid openings has a ring with the ring opening spanning webs.
  • the outer diameter of the ring corresponds approximately to the inner diameter of the corresponding opening of the hearing aid, such that the ring is at least partially introduced into this opening. This advantageously no further, on the surface of the hearing aid outwardly projecting fasteners for microphone protection needed.
  • the ring is designed substantially as a circular, flat disc having a central opening, preferably with a bevel formed on the edge directed in the installed state toward the outside of the hearing aid.
  • the microphone protection can be easily introduced into the corresponding opening in the housing of the hearing aid and has the outside to an optimal shape, so as not to attract dirt itself or to promote the deposition of dirt.
  • At least three webs are formed at a regular distance from each other, which are interconnected in the center of the ring.
  • only a single web can be provided, and thus divide the opening of the microphone protection in two areas.
  • Even the arrangement of more than three bars can be provided, and thus further reduce the remaining openings between the webs, which further complicates the ingress of dirt and moisture.
  • the Stege can on the outside of a convex curvature.
  • the microphone protection as a whole has an outwardly convexly curved contour, which, on the one hand, on the one hand usually visually matches the contour of the hearing aid and, on the other hand, further complicates the deposition of dirt.
  • the microphone protection consists of one piece of plastic.
  • the microphone protection can be produced easily and inexpensively preferably in injection molding.
  • the ring resp. the webs connected directly to a preferably rod-shaped tool, wherein the connection is preferably carried out via at least one dimensioned as a predetermined breaking point connecting web.
  • the microphone protection which has very small dimensions, especially in in-ear hearing aids, can be easily inserted manually into the opening of the hearing aid.
  • the tool can advantageously be easily separated by breaking the connecting web, which can be done by bending or twisting without much effort.
  • the microphone protection remains reliably fixed in the corresponding opening in the hearing aid.
  • the ring, the webs and the tool consist of a single part, which is preferably made of plastic by injection molding.
  • the ring facing away from the end of the tool is designed as a gripping device or fork.
  • this end of the tool can be used to remove a microphone used in the hearing aid again.
  • at least two spring-trained fingers with locking means are available for this purpose. These fingers can be pushed onto a bridge of the microphone protection and at this snap. This is by train on the tool of the microphone protection from the hearing aid resp. pulled out of the opening. This is where the great advantage of the webs of the inventive microphone protection, which allow easy removal without damaging the ring, becomes apparent.
  • projections are formed. These projections serve to clamp disc-shaped elements in the region of the opening of the microphone protection resp. hold.
  • the surface of the microphone protection is at least partially provided with a hydrophobic coating. This coating further impedes or prevents the ingress of liquids into the opening, either directly through the mouth of the microphone guard or across the gap between the microphone guard and the hearing aid.
  • a filter preferably formed as a circular disc, on the inside of the Rings arranged.
  • This filter prevents the penetration of particles into the opening of the hearing aid, which are smaller than the remaining openings between the ring and webs of the microphone protection.
  • the filter is fixed to the ring, preferably glued, arranged or releasably connected to the ring, preferably inserted or engaged.
  • the filter must be replaced either together with the microphone protection itself or it can only be replaced in case of heavy pollution, the filter itself.
  • the filter is made of a fabric of metal wire or natural or synthetic fibers.
  • the fabric is created while leaving gaps between the individual fibers.
  • the filter consists of a non-woven of natural or synthetic fibers.
  • the fleece advantageously passes the sound through to the microphone, but reliably blocks any small particles of dirt or moisture.
  • the filter consists of a porous sintered body of metal, plastic or ceramic.
  • sintered bodies with microperforation are also suitable for this purpose.
  • the hearing aid or hearing aid with at least one opening arranged on the outside, and preferably with a microphone arranged in the interior of the hearing aid or the hearing aid communicating via a channel, and a microphone protection according to the invention has a diameter of the opening which approximately corresponds to the outer diameter of the according to the invention corresponds to microphone protection. Furthermore, stop means are provided in the interior of the opening in order to limit the insertion depth of the microphone protection. By this stop means is reliably prevented that the microphone protection can be inserted further than intended in the opening or independently or unintentionally during operation to the inside of the hearing aid, respectively. the hearing aid moves.
  • the microphone protection is either just flush inserted into the opening or is still a little beyond the edge of the opening. This has the advantage that no dirt can collect in a depression formed above the microphone protection and thus clog the microphone protection.
  • the surface of the inside of the opening is formed at least partially rough, such that a frictional engagement with the corresponding surface of the microphone protection is formed. This can reliably prevent the microphone protection from accidentally coming off the opening and being lost.
  • the use of the microphone protection according to the invention for hearing aids or hearing aids for covering the opening of the microphone, preferably for in-the-ear hearing aids, is claimed.
  • inventive microphone protection is not only suitable for the microphone resp. the microphones of the hearing device leading openings, but also to cover, for example, ventilation openings of the hearing aid.
  • FIG. 1 the view of an inventive microphone protection 1 is shown.
  • This consists essentially of a ring 2 with running towards the center and there interconnected webs 4. Between the ring 2 and the webs 4, an opening 3 is formed.
  • the ring 2 and the webs 4 are preferably formed as a one-piece component and consisting preferably of plastic. Such a component can be produced easily and inexpensively as an injection molded part.
  • the webs 4 are advantageously convexly curved to the center of the ring 2 and thus adapts to the contour of the hearing aid, as is the case FIG. 2 evident.
  • the microphone protection 1 is introduced into an opening 6 of the hearing aid, wherein the upper edge of the ring 2 protrudes slightly outwards or just flush terminates flush with the surface of the hearing aid in this area.
  • the exact position of the microphone protection 1 is achieved in that the opening 6 at the corresponding depth has a shoulder or a stop for the microphone protection 1.
  • the microphone protection 1 can neither be deliberately or unintentionally inserted deeper into the opening 6 than is provided.
  • the diameter of the opening 6 is dimensioned such that a frictional engagement between the opening 6 and the outside of the ring 2 is created.
  • the microphone protection 1 is reliably held and fixed in the opening 5, and can not be inadvertently or independently solved.
  • This frictional engagement can be achieved by appropriate mass of the opening 6 and the microphone protection 1 and be supported by appropriate surface textures of the superposed surfaces.
  • the corresponding tool 7 is connected to the microphone protection 1, as shown FIG. 3 evident.
  • the tool 7 may be formed, for example, as a pen and thus be easy to handle.
  • a gripper or a fork 8 may be formed at the other end of the pin 7, a gripper or a fork 8 may be formed.
  • the one end of the tool 7 is connected via a thin web 9 with the microphone protection 1, as in FIG. 4 shown in more detail.
  • This web 9 is advantageously designed as a predetermined breaking point, ie it can be separated by applying a small force, for example a moment about the longitudinal axis of the tool 7 with inserted microphone protection 1.
  • the microphone protection 1 Due to this design of the microphone protection 1 with integrated tool 7, this can now be easily inserted into the opening 6 of the hearing aid. This does not require a subject-specific skill, so that this can also be carried out simply by the hearing aid wearer. Once the microphone protection 1 is in the desired position, by twisting or bending the tool 7, the connecting web 9 can be separated.
  • the same tool 7 can be used to remove the microphone protection 1 used in the hearing aid.
  • the other end of the tool 7 is advantageously designed as a fork.
  • the fork can, for example, two resilient fingers 8 with locking means 8 ', which can be plugged over a web 4 of the microphone protection 1, as is made FIG. 8 evident. Applying a tensile force, the microphone protector 1 can now be pulled out of the opening 6 and then a new microphone protector 1 can be inserted into the opening 6.
  • either the original tool 7 can be used, or the tool 7 of the newly used microphone protection 1 can be used.
  • the microphone protection 1 just when used in in-ear hearing aids can this by the inventive construction simply by untrained personnel, for example by the wearer of the hearing aid itself, use and replace easily due to the webs 4.
  • the service intervals for hearing aids be extended to today's solutions, since the microphone itself is protected by the microphone protection and this protection is also easily replaceable, which contributes to an overall reduction in costs.
  • the microphone protection 1 can additionally be provided with a hydrophobic coating, whereby the penetration of liquid through the gaps between the ring 2 and the opening 5 and through the openings 3 additionally difficult.
  • an additional filter in the region of the openings 3 of the microphone protection 1.
  • Such a filter additionally protects against the penetration of dirt and moisture into the interior of the hearing device, in particular for the microphone arranged therein.
  • Such a filter 10 may preferably be mounted on the inside of the ring 2, as in FIG FIG. 5 is shown in the supervision.
  • the filter 10 may be formed as a circular, flat body, which is fixedly attached to the inside of the ring 2 or via projections 5 on the inside of the ring 2, as in FIG. 1 shown pressed against the webs 4.
  • the filter 10 may be constructed of a fabric of metal wire or synthetic fibers, which is constructed coarsely meshed. Alternatively, it is also possible to use a nonwoven which is formed from natural or synthetic fibers. Further, the filter 10 may be constructed as a porous sintered body and made of metal, plastic or ceramic.
  • the ring 2 of the microphone protection 1 serves in each case advantageous as a support for the filter 10. It can the filter 10 either be firmly connected to the ring 2, for example by gluing, or mechanically fixed to the ring 2. For example, this is done on the one hand by frictional forces on the inside of the ring 2 and / or by the already mentioned projections 5, which are formed on the inside of the ring 2 and press the filter 10 against the webs 4 and fix.
  • FIG. 6 is still the section through a microphone used in the hearing aid 1 shown.
  • the opening 6 of the hearing aid has at a depth t a paragraph 11, which serves as a stop for the ring 2 of the microphone protection 1. This defines the maximum penetration depth of the microphone protection 1 in the hearing aid.
  • the depth t is dimensioned such that the advantageously bevelled edge 2 'of the ring terminates flush with the edge 6' of the opening 6 and thus no edges or depressions are formed in this area, in which dirt and moisture can be deposited.
  • FIG. 7 Finally, the section through the shell 12 of a hearing aid with microphone protection 1 inserted in the opening 6 is shown purely schematically.
  • the opening 6 opens into a channel 13, which leads to a disposed within the shell 12 of the hearing aid microphone 14.
  • the other located in the interior of the shell 12 of the hearing aid elements resp. electronic components are for the sake of clarity in the FIG. 7 not shown.
