An earpiece (2) for a hearing aid (12) comprises a plug (20) for contacting the meatus of the users ear canal, a contact element (13) for resting against an inside of the users tragus and or the ear canal, and a fixture for holding the plug and the contact element together, the fixture having means for adjusting the spacing between the plug and the contact element. The invention further provides a hearing aid.
Description
Technical field
[001] the present invention relates generally to hearing aids.The invention further relates to the earphone that is used for hearing aids.More specifically, the present invention relates to ear-level hearing aid.
Background technology
[002] hard of hearing formula (BTE) hearing aids generally comprises shell, pipeline and earphone.Hold electronic building brick, microphone and miniature loudspeaker in the shell, be used for pickup, amplification and produce the voice output signal that amplifies.Pipeline provides from the pipeline of shell to earphone transmission voice signal, and earpiece couples enters the acoustic energy of duct from pipeline.In the use, after shell placed external ear, part was hidden.Pipeline, or section of tubing at least for semi-rigid or resilient, make that pipeline also helps hearing aids is placed on user's the external ear.Can make earphone be fit to user's ear by elasticity or customization, so that place the road junction of duct.
[003] EP-A-1448014 provides and has been suitable for allowing that the sound of ear outside imports the earphone of eardrum into.This earphone comprises the elastomer that is used for when earphone is inserted into duct in abutting connection with the concha auriculae bottom.
Summary of the invention
[004] an object of the present invention is to provide the hearing aids that can easily adapt to different user.
[005] another object of the present invention provides and makes easy hearing aids.
[006] another object of the present invention provides the perfect hearing aids that also cosily remains on the user.
[007] another purpose of the present invention provides the hearing aids that the good user's of being acoustically coupled to duct can be provided.
[008] another purpose of the present invention provides part and opens to allow sound to reach user's eardrum, provides the sound of amplification also to reach the hearing aids of user's eardrum simultaneously.
[009] another purpose of the present invention provides and makes easy and can easily adapt to the hearing aid earphone of different user and dissimilar hearing aidss.
[010] according to a first aspect of the invention, the earphone of claim 1 definition has been realized these and other purpose.
[011] earplug provides comfortable part supporting for earphone, and the sound oriented users duct that hearing aids can be amplified.The contact element that leans against ear another part replenishes this supporting.According to the present invention, thereby fixture allow to be regulated contact element scalable hearing aids adapting to the ear and the ducts of different sizes, or about the different choice of pretension.Adjusting device allows custom hearing aid, makes it adapt to users.
[012] in one embodiment of this invention, contact element can partly be oval.The inboard earphone that keeps of user's tragus can be leaned against when using earphone in any other shape of fixed position thereby also can be, for example, circle, ellipse or triangle can be roughly.The ear that can be different sizes is produced the contact element of different size.
[013] in another embodiment of the present invention, fixture comprises a plurality of guide rails.Number may is between 1 and 50.Guide rail can be recessed trough or projection.In addition, contact element comprise can with the interactional some guide rails of the guide rail on the fixture.Number may is between 1 and 50.Guide rail can be groove or projection.Guide rail allows contact element to screw in the selected orientation of relative earplug, thereby makes the assembler to select to lean against the most comfortable position of user's tragus and duct inboard.In addition, rotatory power allow to adjust and fixedly the position of contact element in ear to adapt to different user.
[014] according to an embodiment, fixture comprises elastic device, to improve users'comfort and fitness.
[015] according to another embodiment, but the earphone incremental adjustments.In case assembler or end user's decision, incremental adjustments allow the adjusting and simple the fixing of size.
Can be by for flexible beam, as lattice framing or pole, the locking device that a plurality of grooves is provided and is used for optionally meshing a groove provides adjustment.
[016] beam comprise a pair of relatively, the face of substantially flat, wherein a plurality of grooves are positioned on first.Smooth opposite face makes beam flexible, as is bent into ring.
[017] fixture comprises the end of locking device with built-in beam.
[018] according to an embodiment, locking device comprises rib and resilient strand, and rib is used to mesh a groove.This manufactures and designs easy, but and easy adjustment and fixing.
[019] according to another embodiment, the two sides of beam all has a plurality of grooves.This makes, for example, for being used for left ear and auris dextra hearing aids, beam can arbitrary mode, as combining with the locator that can receive the beam end that enters from the both sides either side, forms ring.In another embodiment, all faces of beam all have a plurality of grooves, and this is built-in beam better.Groove can be used between 0.5mm and the 5mm and the increment setting that preferably changes between 1.5mm and 2.5mm.
[020] according to an embodiment, earphone comprises having the axle and the main body in axis hole, wherein flexible beam with become with axle 45 degree to the 90 degree scopes the angle and preferably to become 55 to spend angle to the 80 degree scopes with axle from Subject Extension.This makes earphone can go deep into duct, and beam partly stretches out the concha auriculae of user behind engagement tragus and the duct.Main body can be roughly cylindrical.If beam is flexible, when the beam end when the either side tangentially of both sides is introduced cylinder-shaped body, locator can only be made as and receive the beam end, so because the angled extension beam distortion of cantilever cardinal extremity.
[021] according to an embodiment, make fixture material can under organize the material and select, comprise polyamide, silicone, polyurethanes, polytetrafluoroethylene, ethyl vinyl acetate, polyacetals, thermoplastic elastomer (TPE), polymer, elastomer and polyformaldehyde.
[022] according to another embodiment, earphone comprises the earplug of contact user auditory canal wall, is used for guiding the voice signal of amplification to enter user's listening tube.
[023] according to another embodiment, earplug is suitable for supporting sound conduit tube, can allow external voice to walk around earplug simultaneously and reach user's inner ear.This has been avoided uncomfortable stifled ear effect.Sound bypass is for the user of slight hearing defect, and is very beneficial as the user of hearing defect is only arranged at band segment, because when they need not auxiliaryly just can hear the time, they can directly hear these sound.
[024] according to another embodiment, earplug is suitable for matching with duct, thereby does not allow external voice to walk around earplug.This helps moderate to the height hearing loss.
[025] the present invention provides hearing aids according to claim 17 in second aspect.
[026] other embodiment are referring to claims.
[027] other purposes, embodiment and advantage are referring to the detailed description part of this explanation.
