Definitions

  • the invention relates to a damping device according to the preamble of claim 1 for vibration-damping (vibration-damping) mounting of a receiver within a hearing instrument.
  • a damping device is out WO 2014/090282 A1 known.
  • the invention further relates to a hearing instrument with a corresponding damping device.
  • Hearing instruments are generally used to describe devices that pick up ambient sound, modify the signal and emit a modified sound signal to the hearing of a person wearing the hearing instrument ("wearer").
  • a hearing instrument which is designed to supply a hearing-impaired wearer and which processes, in particular amplifies, acoustic ambient signals in such a way that the hearing impairment is fully or partially compensated for is referred to here and below as a “hearing aid”.
  • a hearing device usually includes an input converter, for example in the form of a microphone, a signal processing unit with an amplifier, and an output converter.
  • the output converter is usually implemented as a miniature speaker and is also referred to as a "listener" (receiver).
  • hearing instruments that are geared towards fitting for people with normal hearing, in order to protect the wearer's hearing or to support noise perception (e.g. understanding speech in complex noise environments) for specific purposes.
  • Such hearing instruments are often constructed in a similar way to hearing aids and include, in particular also the input converter, signal processing and output converter components mentioned above.
  • BTE hearing instruments Behind-The-Ear, also behind-the-ear, BTE for short
  • a housing equipped with the input converter, the signal processing and a battery is worn behind the ear.
  • the receiver can be arranged either directly in the ear canal of the wearer (so-called ex-receiver hearing instruments or receiver-in-the-canal, RIC hearing instruments for short).
  • the handset is located within the housing itself.
  • a flexible sound tube also known as a "tube,” directs the receiver's acoustic output signals from the case to the ear canal (tube hearing instruments).
  • ITE hearing instruments in-the-ear, also in-the-ear, ITE for short
  • CIC hearing instruments are similar to ITE hearing instruments, but are worn completely in the ear canal.
  • a safe and especially vibration-damped mounting of the receiver within the housing of the hearing instrument is necessary in order to minimize the transmission of airborne and structure-borne noise within the housing and thus avoid acoustic feedback as far as possible.
  • the receiver of a hearing instrument is usually mounted with individually shaped bearings (for each hearing instrument model), which are adapted to the respective receiver design and to the available space in the hearing instrument as well as to the required amplification of the hearing instrument. It is common practice to dampen a receiver by means of a rubber band or a rubber bag that is wrapped around the rear part of the receiver so that the receiver is prevented from hitting the hard housing wall of the hearing instrument.
  • listeners are often Enclosed chambers made of plastic or metal in order to avoid transmission of airborne noise within the housing of the hearing instrument as far as possible.
  • the various functions of the receiver suspension namely the mechanical holding function on the one hand and the vibration damping function on the other, are often in conflict here, since they would require contradictory configurations of the receiver suspension and are therefore difficult to reconcile.
  • a comparatively soft configuration of the earphone suspension would be particularly advantageous in terms of effective vibration damping, but this would be disadvantageous for low-vibration mechanical mounting of the earphone.
  • WO 2014/090282 A1 known damping device comprises a housing for a receiver of a hearing instrument.
  • the housing comprises several parts that can be assembled together. At least one of these parts is made from a harder material and a softer material in a two-component injection molding process.
  • the surface of the harder material has a soft magnetic metallic coating to shield the receiver from magnetic fields.
  • the invention is therefore based on the object of enabling a receiver to be mounted securely and effectively in terms of vibration damping within a hearing instrument.
  • the damping device according to the invention is used for vibration-damping mounting of a receiver within a hearing instrument.
  • the damping device comprises an elastic damping element, a cage connected to the elastic damping element, and a shell surrounding the cage. According to the invention, both the elastic damping element and at least part of the shell have a lower hardness than the cage.
  • the combination of - viewed from the inside out - soft material of the damping element, hard material of the cage and in turn soft material of the shell for vibration-damped suspension of listeners (especially heavy and/or powerful listeners) is particularly advantageous.
  • the material of the inner damping element can be made particularly soft as a result of the supporting effect of the hard cage.
  • a particularly effective vibration damping, in particular at high frequencies, is thus achieved without having to accept a weakening of the mechanical mounting of the earphone.
  • the soft shell is particularly effective for dampening low frequencies; In particular, it prevents vibrations of the cage's receiver from escalating due to mechanical feedback effects.
  • the shell effectively protects the listener from damage caused by mechanical impact, for example if the hearing instrument is dropped.
  • the elastic damping element is preferably made entirely or partially of an elastomeric material and particularly preferably of a fluoroelastomer and/or a fluorosilicone elastomer.
  • the degree of hardness of this elastic material preferably has a Shore hardness (Shore A) in a range between 20 and 30, and particularly preferably a Shore hardness of 25.
  • the shell or its soft part is preferably also made of a fluoroelastomer and/or a fluorosilicone elastomer.
  • the degree of hardness of this elastic material of the shell preferably has a Shore hardness in a range between 50 and 60.
  • the use of the fluoroelastomer "Viton" from DuPont is particularly suitable here.
  • the cage which is harder than both the damping element and (in whole or in part) the shell, is preferably made of a (dimensionally stable) plastic, in particular (reinforced or unreinforced) polyamide or polycarbonate.
  • a thermoset or a (non-elastomeric) thermoplastic is referred to as “dimensionally stable plastic”.
  • the cage can also consist of a metal, for example sheet steel.
  • the shell (also referred to as a box) is designed in two parts. It consists in particular of two half-shells, which are pushed from opposite sides onto the structural unit formed from the damping element and the cage.
  • the two parts of the shell can consist of the same material or of different materials (especially materials with different hardness).
  • An embodiment of the invention is particularly advantageous in which the shell is made of a comparatively hard material in a front area, in particular a dimensionally stable plastic or metal, and in a rear area of a comparatively soft material, in particular the aforementioned elastomeric material.
  • the front area is that area of the shell which the sound outlet of the earpiece faces when installed. and where, in a BTE device, the sound tube is inserted into the shell.
  • the shell is preferably designed in such a way that it encloses an installation space for the earphone - and thus also the damping element reinforced by the cage - in an airtight manner .
  • the shell is designed to be completely closed in order to create a closed volume of air in which the earphone is installed as intended.
  • the volume of air enclosed by the shell is advantageously used as an extension of the rear volume for the receiver.
  • Such an expanded rear volume is required in particular for headphones with a higher output and/or a small receiver housing.
  • the fact that the vibration of the sound-generating membrane also displaces air behind the membrane is particularly noticeable.
  • the membrane oscillations in the air space behind the membrane would cause noticeable pressure fluctuations with short-term overpressures and negative pressures, which would counteract the deflection of the membrane and reduce the efficiency of the receiver (and thus in particular the sound power generated).
  • powerful or particularly small earphones therefore often have a pressure equalization opening (backventing) behind the membrane, so that the air space surrounding the earphone increases the rear volume of the earphone.
  • a listener with backventing emits more airborne sound backwards, so that a hermetic seal of the air space around the listener makes sense in order to avoid crosstalk of the listener sound to the or each microphone of the hearing instrument (with the associated risk of feedback). This is achieved in a particularly effective manner by the above-described airtight design of the shell.
  • the elastic damping element is preferably in the form of a hose that completely encloses the receiver.
  • the damping element is placed on the outside of the earphone around its outer circumference.
  • the front and back of the handset preferably remain open.
  • the elastic damping element expediently comprises holding projections which rest against the receiver in the installed state and thus clamp the receiver between them.
  • the holding projections can be adapted in terms of their size and damping properties to the size and weight of the respective earphone to be stored.
  • the holding projections are designed as conical knobs, the distal ends of which each form a contact surface for the receiver to be stored.
  • the cage is designed in such a way that it surrounds the damping element and that the outer circumference of the damping element thus rests against an inner circumference of the cage.
  • the cage is at least partially embedded in the material of the damping element. This achieves a positive fit between the material of the damping element and the material of the cage, as a result of which the soft material of the damping element is reinforced in a particularly effective manner.
  • the damping element consists of a plurality of unconnected holding projections which are individually connected to the cage, in particular molded onto the cage.
  • the hearing instrument according to the invention has a housing, a receiver and a damping device according to one of the above-described configurations of the invention.
  • the receiver is mounted in a vibration-damped manner within the housing of the hearing instrument by the damping device.
  • the shell i.e. the casing enclosing the damping element and the cage, is adapted in particular to the inner shape of a housing recess of the hearing instrument provided for holding the earphone and rests at least partially on a wall of the housing, so that the earphone has no play and is stable via the damping device held in a designated position.
  • the damping device allows the earphone to be sufficiently mobile to work off (i.e. dissipate) vibration energy, particularly in the higher frequencies.
  • the surface of the shell is optionally structured, in particular notched, in order to reduce as effectively as possible a force transmission due to a movement of the receiver to the housing of the hearing instrument surrounding the shell in the installed state.
  • the structuring of the surface of the shell means that the shell does not rest against the surrounding housing wall of the hearing instrument over the entire surface, but only in discrete areas.
  • the areas of the shell that are not in contact with the housing wall can deform in response to movements of the earphone, in particular bulge, without touching the housing wall, so that a comparatively large proportion of the earphone movements can be absorbed by the shell.
  • the damping device according to the invention is preferably used in a BTE hearing aid. Within the scope of the invention, however, it can also be advantageously used in an ITE hearing instrument, provided that there is sufficient installation space.

  • a sound outlet 13 of the receiver 3 and a rear side of the receiver 3 opposite the sound outlet 13 are arranged on the open sides of the tubular base body 11 .
  • the cage 7 is provided with openings 15 on all sides (ie openings which extend from the inner circumference of the base body 11 to its outer circumference).
  • the damping element 5 consists in the Figures 1 to 4 shown embodiment of a number of unconnected holding projections in the form of hollow conical knobs 17, whose distal ends (ie facing away from the inner circumference of the base body 11) each form a contact surface 19 for the receiver 3.
  • the conical nubs 17 are formed from an elastic material (for example a fluorosilicone) which is softer than the material of the cage 7 and has a Shore hardness (Shore A) of 20-25, in particular 23, for example.
  • each opening 15 of the cage 7 one of the nubs 17 is introduced, in particular injected.
  • the cage 7 and the damping element 5 are preferably manufactured together in a two-component injection molding process.
  • the shell 9 consists of two parts, namely a front half-shell 21 and a rear half-shell 23, these half-shells 21, 23 complementing one another to form an airtight casing for the receiver 3.
