Definitions
- the invention relates to a partial bracket for a Sp Dahlkopfbügel for headphones or headsets, a connecting element for a Sp Dahlkopfbügel and headphones or headsets with such Sp Dahlkopfbügeln.
- Spreading headband are used to ensure a comfortable and secure fit on headphones with headsets or headsets, especially in professional applications.
- the Bügelandruck so the pressure with which the headband presses the headphone shells to the head, should not be too high.
- the spreading of the headband is that at least two part of the bracket are spread apart and thus rest on different positions of the head.
- the object of the invention is to provide a Sp Dahlkopfbügei for headphones or headsets, which spreads automatically when opening or widening, in use retains the spread and in which after the use of the part bracket are automatically brought together.
- a partial bracket for a Sp Dr Drunk for a headphone or a headset with at least two partial brackets for receiving at least one headphone shell at an end portion with a substantially arcuate curvature, wherein the part of the bracket has a resilient spring portion for resilient expansion and narrowing of the partial bracket in which the end regions are rotated relative to the spring region about the longitudinal axis, angled relative to the curvature and can be mounted on connecting elements for generating a mechanical stress in the part clip.
- a corresponding solution of the problem is obtained with a connecting element for a Sp Dreutickopfbügel for a headphone or a headset with at least two partial straps with a substantially arcuate curvature, each partial bar has a resilient spring portion for resilient expansion and narrowing of the partial bracket and two end portions, and two Connecting elements, wherein the connecting element has holding elements to which the end portions of the part yokes are mountable, wherein the holding elements for rotating the end portions relative to the spring portions about the longitudinal axis, for bending the end portions against the curvature and for generating a mechanical stress in the part bracket in the assembled state are designed.
- the invention is based on the finding that, by introducing mechanical stresses into the spreader bar, in addition to the tension caused by the opening or placement of the headphone, an automatic spreading and reconnecting of the spine bars can be effected.
- the corresponding stresses can be generated by a torsion in conjunction with a bend.
- the partial brackets can themselves be designed in accordance with claim 1, wherein even an assembly with conventional connecting elements enables the solution according to the invention.
- conventional partial straps ie those without twisting and bending, can be provided with mechanical stresses during assembly with connecting elements according to claim 9 in such a way that a solution to the problem results.
- the elastic spring area consists continuously of a material, in particular of spring steel.
- spring steel In view of the occurring mechanical stresses in the part of the bracket can occur in a multi-part design at the joints weak points that could break in the course of use. The use of spring steel is recommended, since a favorable production with a good handling and a good quality resistance can be combined.
- the end portions opposite to the spring portion are rotated in opposite directions to each other.
- the torsional stresses introduced at the end regions by this rotation during assembly complement each other.
- the end regions are angled inwardly relative to the curvature in order to introduce a corresponding voltage during assembly.
- the end regions are bent relative to the curvature by an angle in the range of 0 ° to 20 °, preferably in the range of 0 ° to 10 °, in particular by approximately 5 °.
- the partial bracket is configured such that a cable is guided from one end region to the other end region through the partial bracket.
- a cable bushing through a part of the bracket has the advantage that a signal must be supplied to the electro-acoustic transducer of the headphone on only one side of the headphone. A user is not hampered by cables running off the headset on either side of the headset.
- the partial bracket has a sheath for guiding a cable from one end region to the other end region through the Sheathing up. In this way, a corresponding cable management is possible without changing the spring area of the part bracket itself.
- a headset or headset with a Sp Dahlkopfbügel and at least one earphone shell part bracket and / or connecting elements according to one of claims 1 to 9, wherein at least one support for the at least one headset is arranged at the end portions of the part bracket and / or connecting elements.
- FIG. 1 is a front view of a part of the invention with detailed views of the end portions along its longitudinal axis,
- FIG. 2 is a front view, enlarged relative to FIG. 1, of an end region of a part clip according to the invention, FIG.
- FIG. 3 is a side view of the part of the invention shown in Fig. 1,
- FIG. 4 is a front view of a headphone according to the invention.
- Fig. 5. shows a cross section through a part of the invention bow of the headphone shown in Fig. 4.
- FIG. 1 shows a front view of a part clip 1 according to the invention, which in the embodiment shown is arched uniformly arcuate, so that it has the essential shape of a circular cutout over an angular range of slightly more than 180 °.
- the cross section of the partial hoop 1 essentially corresponds to a flat rectangle, the broad sides of the cross section corresponding to the inside and outside of the curvature.
- the detail views 1a and 1b illustrate the rotation of the end regions 2a and 2b along their longitudinal axis by an angle ⁇ relative to the spring region 3, which extends in this embodiment over the entire part of the bracket 1 except the Ent Schle 2a, 2b.
- the angle ⁇ is about 15 °.
- FIG. 1 shows an enlarged front view of an end region 2 a of a part clip 1 according to the invention.
- the end region 2 a is bent at an angle ⁇ , in this case inwardly, opposite a tangent at the transition between arched spring region 3 and end region 2 a.
- the angle ß is about 5 °.
- Fig. 3 shows a side view of the invention shown in Fig. 1 part of the bracket 1.
- the end portions 2a, 2b each have a hole 4, which serves a simple connection between the part bracket 1 and connecting element (not shown here) by, for example, a screw enable.
- the bevel 5 on the spring region 3 opposite end of the end portion 2a, 2b in combination with a corresponding configuration of the connecting element, to limit the spread of the Sp Schwarzkopfbügels to a maximum value.
- the headphone 6 has two partial yokes 1, whose end regions 2a, 2b (not shown) are mounted on or in connecting elements 7a, 7b, which in turn have holders 8a, 8b for receiving Carrying elements 9a, 9b for headphone clams (not shown).
- the part of hoop 1 are spread when using the headphone 6. This spreading is done so that the part of the bracket 1 are tilted forward or backward from the plane of the drawing.
- the headphone 6 can also be designed so that it has only a headphone shell. However, an additional device may be provided on the end regions 2a, 2b or the connecting element 7a, 7b, on which or no headset is attached, which is pressed against the head in accordance with a headphone clam.
- headphone and headset are to be understood as meaning not only devices having electro-acoustic transducers, but also, in a broader sense, devices serving, for example, for soundproofing or soundproofing of the ear.
- Fig. 5. shows a cross section through a part of the invention hoop 1 of the headphone 6 shown in Fig. 4.
- the part of the bracket 1 has a sheath 10 which extends around the spring portion 3 and a passage 11, through which a cable from an end portion 2a, 2b of the part clip 1 can be guided to others.
- a Sp Dr Dr Drettigel with part of the invention and / or fasteners is user-friendly, since it automatically spreads when widening associated with the touch and after use, ie in the narrowed state, the spread automatically reverses. The user is not in danger of pinching hair, as the spread is maintained during use.
