Definitions
- the invention relates to an earphone comprehensive electrical device.
- An ear speaker for the purposes of this document is an electrically operated device, which is intended to be attached directly to the outer part of a human ear so that it at least protrudes into the auricle, and which can produce controlled sound, the intended with that ear to which the device is attached if necessary, is well perceived.
- an ear speaker is either wired or wireless (ie, wireless) in communication with another device, such as a telephone or music playing device, and receives from it the information to be acoustically reproduced.
- a device comprising an ear speaker for example, can also be a hearing device, ie an auxiliary device which serves to compensate for an impairment of the hearing of an ear by amplifying sounds currently arriving from the surroundings in relevant frequency ranges directly at the auditory canal.
- an earphone speaker may also be part of a so-called “headset”, ie a device which contains a microphone in addition to a loudspeaker and information which means sound, in the form of electromagnetic signals by cable or wirelessly with one arranged at a distance Exchanges device.
- headset ie a device which contains a microphone in addition to a loudspeaker and information which means sound, in the form of electromagnetic signals by cable or wirelessly with one arranged at a distance Exchanges device.
- a small two-armed lever is pivotally mounted on the tragus side facing the outer leg, which is to be pivoted by a prestressed spring so that one arm of the lever is pressed against the tragus.
- the bearing of the lever on the leg in question slidably and releasably fixed.
- the cramped space is the Hebe! with the earpiece speaker attached, it is very difficult to access, so that if the earpiece speaker is to hold well on the ear, it is difficult to remove the earpiece and can also become painful.
- DE 3328100 A1 shows an electrical device serving as a hearing device, which has a microphone, loudspeaker, battery and electronic amplifier circuit.Accordingly, it perceives ambient noise with the microphone and amplifies part of the frequency spectrum of these noises at the loudspeaker Attached to the ear, the device is clamped to the earlobe, optionally additionally held with a bow around the outer ear. The majority of the mass of the device is at the level of the earlobe, from this massive part of an arm protrudes at the end
- the clamp with the aid of which the earlobe is to be clamped is designed as a pair of two-armed levers, which are held pivotably against one another, where di E two levers can be pressed by a snap mechanism relative to each other either in one of two possible Endstel- lungs.
- US Pat. No. 5,222,151 A and JP 9294296 A show earphones of currently frequently occurring form.
- the approximately circular disk-shaped housing is inserted in the auricle within the area lying between the tragus and the antitragus, wherein the disc plane is oriented approximately vertically.
- the antitragus is a small cartilaginous mass at the lower part of the border of the entrance to the external auditory meatus.
- a cable grommet protrudes approximately parallel to the disc plane and approximately parallel to the gap between tragus and antitragus.
- the main feature of the ear speaker is its weight, which means that it hardly needs any clamping force, which is pleasant to the touch, but the disadvantage is that the earpiece easily falls out during sports activities, etc., and closes the external auditory canal when it sits well.
- the earphone is provided with an additional surface which is provided on the outside of the lower parts of tragus and Antitragus and, with appropriate dimensioning, the seat of the earphone echers something improved.
- a disadvantage of the construction shown is, above all, that the attachment of the device to the tragus is a difficult process that requires some skill. If the tragus is relatively thick, so that relatively high force is required to spread apart those thighs between which the tragus has to be clamped, pushing the device onto the tragus can also cause pain. If the device is designed in such a way that the said force does not become so high that it can cause pain, it can be too low with a thin tragus, so that the device does not hold securely.
- US 2010114153 A1 and US 5662679 A show acupressure clamps for clamping the tragus.
- the acupressure is a healing method according to which on a body part over a period of time a blunt, sometimes quite painful, pressure is applied.
- the terminals according to US 2010114153 A1 and US 5662679 A each consist of two two-armed levers and an approximately U-shaped Vietnamesesbü- gei.
- the elastically flexible connecting bracket is monolithically connected at one leg end approximately with the longitudinal center of a respective two-armed lever. Movement towards each other (by pressure) of two mirror-symmetrical lever ends of both two-armed levers causes the remaining two lever ends to move apart.
- the acupressure clamp can be clamped onto the tragus like a clothespin that has become very short.
- the force applied to the tragus after clamping by the clamp depends to a great extent on how thick the tragus is.
- the object underlying the invention is to provide a device comprising an ear speaker which is to be fastened to a human ear by holding it is clamped on the tragus, so that it presses with a lever from the inside to the tragus and presses with a second lever from the outside to the tragus.
- the device to be newly provided is said to be better in that the attachment and removal are simpler and at least painless, and that the device still reliably and independently supports the tragus regardless of how thick it is Tragus is.
- the device can also be conveniently, safely and nondestructivelyratikiernmg in all sorts of places other than the tragus, if necessary, for example, on another part of the pinna or on a part of the clothing of a person, or on a part which the device should be fixed for storage when not in use.
- the device comprising an ear speaker has two levers that are pivotally connected to one another.
- a resiliently biased part is engaged with both levers and causes by its elastic biasing force a torque between the two levers about the common pivot axis, so that those two Hebei Schluggere, which abut intended mounted on tragus from opposite sides of the tragus, in the absence of other forces, be moved towards each other.
- the improvement according to the invention to these known features comprises two features which are ideally used in combination with each other, but with which each one of the objects underlying the invention can be solved individually.
- the first of these two features is the two levers each two arms form, the pivot axis is located in the respective lever longitudinal direction of the ends of both levers and the pivot axis further when properly attached to the device at one ear outside the normal projection on the surface of the tragus.
- the second of said two features is that that resiliently biased member which creates a torque between the two levers about the common pivot axis is formed and arranged as a spiral spring which is pre-curved by more than 360 ° .
- spiral spring in this document means an elastic spring made of an elastic material, which is intended to be in contact with two other parts (in the present case, the two pivoted levers) at two clamping points, these two other parts guided against each other are movable and the concomitant movement of the clamping points causes an increase or decrease of elastic bending deformation of the spring.
- pre-curved in this context means that the spiral spring consists of an elongated or flat material which is plastically pre-curved with respect to its straight stretched state about the axis of the intended elastic bending deformation.

- Fig. 10 shows in oblique view the device of Fig. 9 as a whole.
- a device 6 according to the invention is clamped on the tragus 2 of the outer ear 1.
- the device 6 has a housing 7, which is located in the cavum conchae 4 (FIG. 1) and in the area of the entrance 5 (FIG. 1) in the external auditory canal and rests against the inside of the tragus 2.
- a loudspeaker is mounted in the housing 7, to which the associated loudspeaker opening 8 (FIG. 4) is located on that side of the housing 7 which, when the device 6 is attached to the tragus 2 as intended, enters the external auditory canal of the relevant ear has.
- a planar lever 9 is formed, which is at device 6 mounted on the tragus 2 as intended, approximately parallel to the plane of the tragus 2 on the inside of this plane and from the tragus 2 beyond the tragus edge 3 to the rear away stands ("behind" of that person who carries the device 6).
- Another flat lever 10 is also aligned approximately parallel to the plane of the tragus 2 and is located on the outside of the Tragus 2 3n.
- a cable grommet 13 is integrally formed on the housing 7, through which a cable extends into the housing 7 (see also Fig. 4).
- the pivot axis 12 is encompassed not only by the bearing brackets 11 but also by the helical-shaped central part of an elastically prestressed part 14 formed as a bending spring.
- the two Schenket of elastically deformable. Part 14, that is, the wire ends of the spiral spring protruding from the central helical wind-shaped part, are under elastic preload pressure on each of a lever 9, 10, respectively on that lever arm 15, 16 which when properly attached to the Tragus 2 device 6, viewed from the pivot axis 12 of the tragus 2 facing away iiegt, and not facing this.
- the legs By applying pressure to said lever arms 15, 16, the legs, in the absence of other forces, cause the two levers 9, 10 to be pivoted in such a way that the lever arms 9, 10, opposite the lever arms 15, 16, which have the intended contact areas 17, 18 with the tragus 2, are pivoted towards each other until they either rest against one another or rest on opposite sides of a part (typically the tragus 2) lying between the two hips.
- the relative position of the levers 9, 10 relative to one another shown in FIGS. 3 and 4 can therefore only hold them stably if the two lever arms 15, 16 are pressed toward one another either by an external action (not shown) or if the two Levers 9, 10 abut with the two contact areas 17, 18 from opposite sides to an object arranged between these contact areas.
- the axis of the pivotal movement of the lever 9, 10 thus include between them. This forces the pivot axis 12, about which the two levers 9, 10 are pivotable relative to one another, to lie against the surface of the tragus 2 when the device 6 is attached to a tragus 2 as intended.
- the bearing surfaces of the levers 9, 10 on the tragus 2 can be readily dimensioned so that they are of the order of 0.5 square centimeters.
- this bearing surface is a compressive force of 0.3 N ⁇ according to the considerations below for holding the device on the tragus sufficient just enough to be clearly perceived at least immediately after the power build. By no means is it so great that it leads to the sensation of pain.
- the surface of the contact regions 17, 18 is made rough, for example corrugated, then its coefficient of friction with human skin is increased compared to a smooth design. You can then still with significantly lower contact force of the lever 9, 10 on the Tragus 2 find the Aus GmbH.
- the distance between the pivot axis 12, 25, 26 of the lever 9, 10 and the center of the contact areas 17, 18 is at least about one centimeter. If this distance were significantly less, with extremely thin or extremely thick tragus, the contact regions 17, 18 could rest against the tragus 2 at an obtuse angle and thus with a disturbingly small contact surface.
- the pivotable levers 9, 10 are two-armed, the advantage is achieved in comparison with a one-arm lever design that the lever arms IS, 16 facing away from the tragus 2 only engage with each other for attachment and detachment of the device 6 on the tragus 2 must be pressed to open the clamping area between the levers 9 and 10.
- a lever 9, 10 presses against the tragus 2 and causes friction due to pain.
- FIG. 5 shows a sketch of an apparatus 19 according to the invention, which differs in two respects from the apparatus according to the invention from FIGS. 2 to 4:
- the arms of the two-armed Hebei 20, 21 are substantially not straight, but each of these arms 20, 21 is curved about parallei lying about the pivot axis 25 axes by about 90 *.
- the curvature is oriented such that the lever arms 72, 23 arranged away from the tragus 2 in the plane lying normal to the pivot axis 25 are away from the plane of the cavum concha 4 when the device 19 is mounted on the tragus 2 as intended. It may perhaps be more difficult to achieve such a pleasing appearance as with the device 6 outlined in FIG. 2 to FIG. 4, but better handleability is achieved in attaching, adjusting and removing the device 19 on the tragus 2.
- That elastic part 24, which acts on the two pivotally held together two-armed lever 20, 21 with a counteracting torque, in the case of FIG. 5 is not a separate from the levers 20, 21 separate part. Instead, the elastic member 24 is monolithically fused with both levers 20, 21. It is designed such that it is well bendable about the intended pivot axis 25 between the two two-armed lifting devices 20, 21. As outlined, for example, it may have the shape of a curved blade, with all the bending axes being parallel to the intended pivot axis 25.
- elastic part 24 a part of a rubbery soft Materia! like silicone or to use a foamed elastic plastic.
- a part could serve as a train pressure or bending spring between the mutually schwenkba ren levers 20, 21 or as (sole) connecting part between them.
- a device 6, 19 according to the invention can be provided with an off switch, which can be actuated automatically by pivoting the levers 9, 10 or 20, 21 towards one another in such a way that the intended contact areas with the tragus 2 are almost or completely touch. This automatically turns off the unit when it is removed from the Tragus 2 and released, or when it is clamped to a very thin storage box.
- the circuit breaker may be, for example, a mechanical switch, whose contacts are swiveled with said hebone. He can For example, but also be an optical, capacitive or inductive proximity sensor, the distance of areas of the two Hebef 9, 10 and 20, 21 detected each other and accordingly sound when exceeding or falling below specified threshold values sounds.
- resiliently biased member which applies the required driving force for pivotal movement of the levers does not necessarily have to extend about the pivot axis of the pivotal movement of the mutually pivotable levers. It can also lie entirely on a single side radially next to the pivot axis. An embodiment for this is outlined in FIG.
- the two two-armed levers are pivotally supported on each other about the pivot axis 26.
- the elastically prestressed part 27, which acts as a bending spring and acts on the two levers by pressure, is arranged on one side radially next to the pivot axis 26, without enclosing the pivot axis 26.
- the charger for charging the battery and the ear speaker comprehensive device so coordinated form that the required for charging electrical connections between the device, which includes an ear speaker, and the charger are producible so that the first device is clamped on an area of the charger the same as otherwise on a tragus.
- the charging device requires an extension which can be clamped in between the two areas which are moved towards one another by the elastically prestressed part and which has electrical contacts on the surfaces which are then in contact with these levers. At the then in contact surfaces of the lever, the corresponding charging contacts are to be attached.
- Ear loudspeakers of the type according to the invention can not only be well attached to the tragus 2 of an ear, they can also be well attached to a garment, for example a collar or jacket on the collar or on the upper edge of a shirt pocket.
- the elastically prestressed part which generates a torque between the two levers about the common pivot axis, is designed and arranged as a spring, which is pre-curved by more than 360 ° .
- the elastically prestressed part 14 is designed as a spiral spring with a central, helical thread-shaped part. If at otherwise same Boundary conditions (wire thickness, diameter of the turns, length of the legs) the number of turns of the central helical part is increased, so the key effect is that the spring characteristic is flatter, and that the range of the possible elastic deformation path is greater.
- the central helical thread-like part of the elastically prestressed part 14 formed as a bending spring has approximately four and a half turns, that is to say a bend angle of approximately 1600 degrees.
- the two tines of the elastically prestressed part 14 rest on the two-armed levers 9, 10 (FIG. 3) and, if necessary, pivot them or, if necessary, pivot them through them.
- the maximum range within which the levers 9, 10 are normally swiveled during normal operation is a maximum of about 40 degrees, ie only about a fortieth! that Winkeis to which the elastically biased part 14 is bent as a bending spring plastic and elastic.
- the ordinate value describes which force is applied by the contact surfaces 17, 18 to a body clamped between them, when a torque is applied to the levers 9, 10 only through the tine of the elastically prestressed part 14 designed as a bending spring.
- the force distribution over the angle a is largely linear and it is very flat in the considered range, i. between minimum and maximum opening angle, the height of the force F changes only by a few percent. That is, in ears in which the tragus 2 is very thick, the contact pressure by the levers 9, 10 de facto the same size as in ears in which the tragus 2 is very thin.
- the contact force F can thus be adjusted precisely to the fact that the device 6 is held securely, but nevertheless no disturbingly large pressure force on the tragus 2 occurs. Good results are achieved when the force F about is at three times the weight of the device 6.
- a device usable as a telephone part - which contains a loudspeaker, a microphone, a Bluetooth transceiver unit, further electronics and a battery - typically has a mass of about 10 grams. Thereupon, a weight force of about 0.1 N acts thereon. against this weight force, the device is already very well held on the tragus 2 when the force F, with which the two pivotable levers 9, 10 press against the tragus 2 is only 0.3 N.
- the bearing surfaces of the levers 9, .1.0 on the tragus 2 can be readily dimensioned so that they are of the order of 0.5 square centimeters.
- a compressive force of 0.3 N is just just large enough to be able to be clearly perceived, at least immediately after the power construction. By no means is it so great that it leads to the sensation of pain.
- a pre-curvature of the elastically prestressed part 14 designed as a bending spring-as shown in FIG. 4-by more than four complete revolutions leads to very easily obtainable requirements with respect to material properties and other dimensions of this part 34.
- a marked improvement over the known construction methods of devices in which the part to be regarded as a bending spring 14 is only precambered by half a turn, can be achieved even if the initial curvature of the spiral spring is more than 360 * . Since the legs protrude approximately parallel to one another in the same direction from the central screw thread-shaped part, about one and a half revolutions are particularly advantageous.
- the first choice for the material of the spiral spring is certainly spring steel. If the dimensioning is adapted accordingly, however, materi- Usable in terms of elastic properties (elastic deformation range, creep, fatigue strength) and modulus of elasticity are not as advantageous as spring steel. With regard to the pivot axis of the levers, the axial dimension on the cross-sectional area of the strand material of the flexible spring is to be increased and possibly the radial dimension reduced and the number of windings increased.
- a ßiegefeder invention When a ßiegefeder invention is used as a resiliently biased member 14, that is one which * is pre-curved by more than 360 and, accordingly, has such a flat spring characteristic in that the force with which the intended therebetween the tragus 2-clamping lever, in the relevant angular range is approximately constant, the levers may not necessarily be two-armed as shown in the drawings, Figs. 2-6.
- FIG. 7 shows a construction for a device 28 according to the invention in which the levers 29, 30 pivotable relative to each other for clamping the tragus between them are one-armed levers.
- the intended to be arranged on the inside of a tragus lever 29 forms in this case, the housing for to be mounted in the device 28 functional parts such as an ear speaker.
- the device 28 can be pushed onto the tragus, which also has approximately the shape of a flat surface, and also by moving in the opposite direction be deducted from it again.
- the contact pressure of the levers 29, 30 on the tragus is so low that no painful friction occurs even though the device 28 is safe after being attached to the tragus is held.
- FIGS. 9 and 10 illustrate how a device 37 according to the construction initially discussed with reference to US Pat. Nos.
- 5,222,151 and JP 9294296 A contains an ear speaker in a housing 38, the housing 38 being intended to fit between the tragus and the anti-tragus is inserted, can be supplemented by a holding device 39 to form a device 40 according to the present invention.
