Definitions

  • the invention relates to a universal ear piece for attaching an acoustic device to a human ear and a communication device with such an ear piece.
  • an ear piece may be part of a headset and may house an electro-acoustic transducer for delivering an acoustic signal to an auditory canal of a user.
  • the ear piece can be designed as a headset for a mobile phone.
  • the earpiece may also be the housing of a hearing aid which, in addition to an electro-acoustic transducer, additionally comprises at least one input transducer, e.g. a microphone, and a signal processing processor.
  • the ear piece may also be formed as part of a wearable on the ear communication device. The ear piece then serves at least predominantly only for holding the communication device to the ear.
  • the communication device is, for example, a headset for a mobile telephone, in which a wireless signal transmission is provided between the headset and the mobile telephone.
  • ear pieces for holding acoustic devices on the ear is often the problem that the attachment is insufficiently effective and, for example, rapid head movements cause the acoustic device from the ear triggers.
  • One way to avoid this is the use of individually adapted to the respective earpiece support ear pieces, which protrude in particular deep into the ear canal of the wearer and thus provide a good fastening effect.
  • custom-made ear pieces are expensive to produce and therefore expensive.
  • a headset for fixing a functional device is known. This is provided for attachment of an acoustic device to an ear of a user with an insert body for insertion into the concha. On the insert body of the earpiece is a flexible, rigid strap attached to the concha.
  • a universally fitting ear piece is known, which is partially inserted in the worn state in the ear canal of a user.
  • a resilient element is attached, which is pushed when creating the ear piece with your fingers in the concha of the ear in question.
  • the correct application of the known ear piece usually succeeds only with practice and a lot of tact.
  • Object of the present invention is to provide a universally fitting ear piece, which provides a good support on the ear and is easy and quick to create. It is another object of the invention to improve the attachment and fixation of an acoustic device to the ear.
  • a universal ear piece for attaching an acoustic device to an ear of a user with a main body, a projecting at the earpiece into the auditory canal of the user ear canal and a resilient element, wherein the main body, the ear canal pin and the resilient member so sized and aligned with each other, that the ear piece is at least substantially positionable in the concha (D, G) of the user's ear and fixable solely by a rotational movement of the earpiece in the concha. Furthermore, the object is achieved by an acoustic device with such an ear piece.
  • FIG. 2 shows the distal side of a earpiece 1 that can be worn in the right ear when the ear piece 1 is worn according to the invention.
  • the earpiece 1 comprises a bulbous main body 2, which merges into an ear canal pin 3.
  • the ear canal pin 3 projects partially into the auditory canal of the right ear of the wearer.
  • the auditory canal pin 3 is slightly tapered relative to the bulbous main body 2, wherein the underside of the bulbous main body 2 passes straight into the auditory canal pin 3.
  • the bulbous main body 2 merges into a resilient element 4, which is designed as an elongated, slender, substantially pin-shaped extension of the main body 2.
  • the resilient element 4 and the auditory canal pin 3 are aligned at an angle to each other, which is between 60 ° and 100 °, preferably at about 80 °.
  • the transition between the resilient member 4, the main body 2 and the ear canal pin 3 is flowing on the left and lower sides of the earpiece 1, respectively.
  • the main body 2 is arc-shaped in its transition region 5 between the resilient element 4 and the auditory canal pin 3.
  • this smooth, curved course of the earpiece 1 allows a rotational movement an ear piece 1 inserted into the concha of a respective ear. By such a rotational movement, the ear piece 1 can be fixed in the auricle of the wearer.
  • the fixation takes place essentially by three areas in which the earpiece 1 rests against the user's ear. These are the area B, which projects into the auditory canal and rests against the upper side of the mouth region of the auditory canal. Furthermore, the ear piece 1 is in the region of the arc 5 of the main body 2 and in the region A of the resilient member 4 along the anthelix L of the right ear.
  • the special alignment and dimensioning of the components of the earpiece 1 allows easy, fast and secure fixation of the earpiece 1 in almost all human ears.
  • the diameter of the ear canal pin 3 is relatively small, preferably in the range between 5 and 8 mm.
  • the ear canal pin 3 can be rotated in the region of the auditory canal entrance and does not necessarily have to point exactly in the direction of the auditory canal.
  • the longitudinal extent of the main body 2 and the resilient element 4 is together about 20 mm to 30 mm, preferably about 25 mm, the longitudinal extent of the main body 2 and the auditory canal pin 3 together about 16 mm to 26 mm, preferably 21 mm.
  • the ear piece 1 is preferably at least partially made of a soft rubber material, whereby the wearing comfort is increased.
  • the soft rubber material advantageously has a Shore hardness between 40 shore and 90 shore, preferably about 50 shore.
  • the soft rubber material also helps to avoid acoustic feedback.
  • the ear piece 1 can thus be produced with an acoustic channel in its interior in only one operation. Interfaces between several parts are thereby avoided.
  • FIGS. 3 to 5 show further views of the earpiece according to FIG. 2.
  • the proximal side of the earpiece is shown 1 shown in FIG 2. This side is facing the head of the wearer with the earpiece 1 supported, thus it is the proximal side of the earpiece 1.
  • main body 2, ear canal 3 and resilient element 4 of the earpiece 1 this view to take a sound outlet opening 6.
  • This opening can be seen in the view according to FIG. 3, but not in the view according to FIG. 2, since the auditory canal pin 3 as a whole extends in the view according to FIG. 3 out of the plane of the drawing or in the view according to FIG.
  • FIG. 5 shows a view of the earpiece 1 according to FIG. 2 from above, that is to say in the direction of the resilient element 4. Also from this view, the smooth, curved course of the earpiece 1 as well as the auditory canal pin 3 protruding into the auditory canal of a respective ear can be seen.
  • FIGS. 6A, 6B and 7. The insertion of an ear piece 1 according to the embodiment illustrated in FIGS. 2 to 5 is illustrated in FIGS. 6A, 6B and 7.
  • the figures show a right human ear, wherein essentially only the relevant in connection with the invention regions of the ear are drawn.
  • the ear piece 1 is guided in the concha D, G of the right ear, the ear canal pin 3 is already pushed a little into the ear canal 9 into it. It then takes a rotational movement in the direction of the arrow shown until the ear piece 1 is finally in the position shown in Figure 6B, in which a slight further rotation of the earpiece 1 in the direction shown is no longer possible.
  • the ear canal pin lies 3 in a front region B at the auditory canal entrance of the right ear and in the arcuate region 5 of the main body 2 and with the resilient element 4 and in particular in its front region A along the anthelix L of the right ear. Furthermore, in this position, the main body 2 is partially hidden by the tragus H and the antitragus I of the right ear. As a result, the earpiece 1 undergoes a relatively secure hold in the right ear. Different ear anatomy is particularly taken into account that in one ear only a relatively small rotational movement in the direction shown is possible, while in another ear, the earpiece 1 can be rotated relatively far until a noticeable resistance is achieved.
  • the length of the resilient element 4 is selected so that it completely inserts as a result of the rotational movement in the concha D, G and rests along the Anthelix L.
  • An additional positioning of the resilient element 4 with the fingers is not required in the dimensioning and alignment of the resilient element 4 according to the invention.
  • FIG. 7 illustrates the end position of the earpiece 1 according to FIG. 6B from a different perspective.
  • this view in particular the curvature of the auditory canal 3 in the auditory canal and the position of the area B, in which the auditory canal pin 3 rests against the auditory canal entrance, are recognizable.
  • the invention has the advantage that the fixation of the earpiece 1 in the ear after insertion into the concha D, G is effected solely by a simple and very quickly learnable rotational movement. Furthermore, the invention offers the advantage that by means of a relatively simple shaping of the earpiece 1 a secure fixation of the earpiece 1 can be achieved in almost all human ears. In particular, the fixation is so secure that the earpiece as a carrier an acoustic device can be used, which can reach a multiple of the size of the ear piece and yet securely held on the ear.
  • FIG 8 illustrates an embodiment of an earpiece 10 according to the invention, which is simultaneously formed as a housing of a hearing aid that is portable in the ear.
  • the earpiece 10 thus comprises, in addition to an ear canal pin 13, a resilient element 14 and a bulbous main body 12 also an input transducer, which is preferably designed as a microphone 15, a signal processing unit 16 for processing and frequency-dependent amplification of an acoustic input signal received by the microphone 15 and a handset 17, which provides an acoustic output signal and outputs via a sound channel 18 in the ear canal of a user.
  • the hearing aid device designed in this way in the ear can be used universally with regard to its fit and can therefore be produced correspondingly inexpensively.
  • the special shape according to the invention gives it a comfortable and secure fit in the ear.
  • FIGS. 9 and 10 A further exemplary embodiment of the invention is shown in FIGS. 9 and 10.
  • an earpiece 20 according to the invention is illustrated in two different views, which is equipped with a fastening device for fastening an acoustic device (not shown).
