Description

Headphone cup

The invention relates to a headphone shell for headphones or headsets for a user who wears glasses with the glasses temple resting on his ear, with a

Headphone shell housing, in which a sound transducer is arranged, and a circumferential ear pad lying on the ear of the spectacle wearer or enclosing the ear, the circumferential ear pad having an interruption in the area of the temple.

Such headphone shells are known from CN 207692005 U. The headphone shell described there has an ear cushion that has a recess on which a slide is provided within the cushioning material with which the recess can at least partially be closed. A locking button is provided on the slide. Furthermore, the ear pad is rotatably supported on the headphone cup.

JP 2009060348 A has headphones for glasses wearers to the content, which is through a

Rotation mechanism is adjustable. These headphones are equipped with a fixed mounting bracket, which is placed around the user's ear and corresponding recesses are provided on this mounting bracket for the glasses temple. The transducer housing is then arranged on this fixed holder at a distance from the ear. This writing thus shows an open headphone without ear pads resting on the ear.

WO 2010/147491 A1 shows ergonomically advantageous headphones for spectacle wearers in which a recess or a channel for a spectacle temple is provided in the auricle.

US 2017/0094400 A1 shows a headset device or a

Headphone shell with a circumferential ear pad that surrounds the ear or the ear, i.e. a closed shell headphone system in which a through opening or a through channel is provided for the temples of glasses. However, this opening is not adjustable and can therefore only be used for certain types of glasses and also only for a certain physiognomy of the user.

Likewise, in DE 20 2017 004 510 U1, a recess or changed property in a certain area of the foam insert for headphones is described, which means that adjustability and customization is not possible.

A similar adaptation is described in US Pat. No. 8,638,969 D2 for an ear pad of a headphone.

US Pat. No. 5,920,911 describes a headphone shell with particularly easily adaptable ear padding, which is intended to allow a temple to be passed through at any point without excessive load pressure. Despite the lamellar structure of the ear pad, a However, the remaining pressure on the temples that are passed through can lead to pressure points and discomfort if worn for a long time.

Furthermore, from US 9,049,512 B1 and US 2017/0366890 A1 derived therefrom, a headset with a headphone cup is known in which a slider-closable passage opening for spectacle temples is provided in the ear cushion of the headphone cup. In this way, eyeglass temples with different strengths can be used and, at the same time, the best possible sealing of the closed headphones from the environment is made possible. Nevertheless, an individual adjustment of the headphones to the respective

Physiognomy of the user not possible.

Based on the prior art mentioned in the introduction, it is therefore the object of the invention to achieve the simplest possible adaptability of a headphone shell for a wearer of glasses, so that headphones and glasses can be used simultaneously for each individual user over long periods of wear.

This object is achieved with a headphone cup according to claim 1.

This makes it possible to adapt the headphone cup and in particular the ear pad to each pair of glasses and each position of the glasses on the head and on the ear, so as to significantly improve wearing comfort. Accordingly, wearers of glasses can wear a closed headphone system without fatigue and pain over long periods of wear of several hours

Wear a headphone cup and circumferential ear pad and thus take full advantage of the acoustic shielding from ambient noise. This prevents contact between headphones and glasses, pressing the headphones on the ear and pressing the glasses against the head. This makes it easier for people who wear headphones to wear headphones, regardless of the physics and type of glasses used by the user. The special thing is that the headphone shell can be adapted to any pair of glasses and the physics of the user (physiognomy) and can therefore be personalized without restrictions. The ear pad consists of an interrupted ring. The interruption offers space for the temple and can be enlarged by compressing the foam and reduced by decompression. The ear pad is connected to elements that can be moved relative to one another in a guide in order to enable compression and decompression distributed over a circumferential area of the headphone cup.

When the circumferential ear pad is attached at one point or over a circumferential area up to half the circumference on the headphone cup housing, a portion of the circumferential ear pad is firmly attached to the headphone cup housing, with the remainder of the ear pad being attached to individually arranged, sliding elements. Between the elements and the point or circumferential area fixed to the headphone shell housing (Fixing point), distances are provided in each case so that when the ear cushion is adjusted via the actively movable push element, stretched or compressed areas of the ear cushion are formed there.

Because the first actively movable thrust element is arranged adjacent to one side of the interruption in the guide, the first actively movable element can be moved via this

The opening width of the interruption can be adjusted.

If a second actively movable push element is arranged adjacent to the other side of the interruption in the guide, the width of the interruption and, in addition, its position can be selected within certain limits depending on the extensibility or compressibility of the ear pad by adjusting both actively movable push elements .

In order to prevent the respectively selected width and / or positioning of the interruption on the ear pad from changing during the use of the headphones, the first and / or second actively movable push element is guided in the guide in a self-locking and / or lockable manner.

Because the first and / or second actively movable pushing element has an outwardly guided lever or a gear that can be rotated via a knurled wheel for moving the pushing element (s) actuated by the user, the user can comfortably adjust the actively moving pushing elements, especially their

Adjustment and fine adjustment. This process is controlled, for example, via a transmission.

The fact that the headphone shell housing is constructed in two parts from a transducer housing and an ear pad support that carries the ear pad on the guide, with a support bracket attached to the transducer housing that leads over the user's head to a second headphone shell, and the ear pad support around an orthogonal to the from

Ear cushion spanned plane arranged axis of rotation is rotatably attached to the transducer housing, the position of the interruption in the ear pad can be adjusted by turning the ear pad holder on the transducer housing over a larger range (angular range of 90 °, for example. The auricle consists of several

Elements that can be positioned relative to one another and thus enable the ear pad to rotate. This counteracts a deposition of the glasses on the bridge of the nose of the user, since contact between the ear pad and the temple is reliably avoided. The glasses can thus be worn on the nose in a perfectly customized orientation for the user. If the first actively movable push element is arranged adjacent to one side of the interruption in the guide, with the ear pad being attached to the ear pad wearer on the other side of the interruption, the first actively movable push element is solely responsible for adjusting the width of the interruption, while the positioning of the Interruption in the desired angular position by twisting the ear pad holder on the

Sound transducer housing takes place around the axis of rotation.

If the guide is arranged in the shape of a ring to the axis of rotation, the positioning of the ear pad remains constant relative to the axis of rotation. Furthermore, a circular guide is mechanically easier to implement by means of elements which can be displaced therein and which consist of corresponding circular sections. Of course, a slightly elliptical design of the guide is also possible.

A further improvement in wearing comfort is achieved if the ear pad has a

Has foam filling made of permanently elastic shape memory foam, since the ear cushion can then be individually adapted to the head and ear shape of the respective user.

An exemplary embodiment of the invention is described in detail below with reference to the accompanying drawing.

In it shows

a) a cross section,

b) a sectional view in plan view along line b-b in FIG. 5a and c) a section in plan view along line c-c in FIG. 5a.

In FIG. 1, headphones 100 in the form of a headset with a microphone 15 are shown in a three-dimensional view. The headphone 100 has 2 headphone shells 1, 1.

FIG. 2 shows a view of how the headphones 100 are worn on the head of a user P who is wearing glasses G with glasses temples T. As can be seen from FIG. 1, on the side of the headphone cup 1 facing the head or the ear of the user P, a circumferential ear pad 2 is provided which surrounds the ear of the user P or rests on it. This type of headphones 100 are therefore also referred to as closed headphones, since the ear cushion 2 is acoustic

Shielding of the transmitted or output audio signals in the

Headphone shell 1 in the vicinity of and to the extent that a particularly intense and undisturbed listening experience for the user P is permitted.

However, since the eyeglass temples T are also arranged on the ears of the user P in the case of spectacle wearers, pressure points occur when using such closed headphones with circumferential ear pads 2 which lead to pain in the head and / or ears of the user P. It has therefore already been proposed in the prior art to provide a recess or interruption 21 in the circumferential ear pad 2. This can also be seen from FIG. 1 and in combination with the eyeglass temples T in FIG. Likewise this is

The situation can be seen in the orthogonal view according to FIG. 3. The respective

Headphone shell 1 consists of a headphone shell housing 10 in which the components required for headphones are accommodated and on which the circumferential ear pads 2 are arranged on the inside, that is to say directed towards the ear of the user P.

A headphone cup 1 according to the invention is shown in FIG. 4 in a three-dimensional view obliquely from the inside. The opening of the headphone shell housing 10, which is directed at the ear of the user P, is thus visible. The circumferential ear pad 2 with its interruption 21 can also be seen on this side. As can be seen in particular from the sectional view according to FIG. 5a, the headphone housing 10 consists of a sound transducer housing 11, which in FIG. 5a represents the lower, shell-like component and contains the sound transducer, which is no longer shown here, for generating the audio signals, as well as an ear pad support 12 , which is connected to the transducer housing 11, but is designed to be rotatable about an axis of rotation D.

The axis of rotation D is oriented orthogonally to the plane spanned by the ear pad 2 in the center of the preferably circular headphone shell housing 10. The ear cushion 2 is arranged on the ear cushion carrier 12. In this case, however, a guide 13 in the form of an almost completely circular recess (groove) is provided in the ear pad support 12, in which the displaceable elements 22 and an actively movable push element 23 along the

Guide 13 are movably anchored. This situation can be seen in particular from the sectional plan view according to FIG. 5b. In the embodiment shown here, four displaceable elements 22 are arranged at a distance from one another.

The actively movable thrust element 23 has an annular section which occupies approximately half of the circumference of the groove. On the actively movable thrust element 23 is on At one end a toothing is arranged for the engagement of a gearwheel of a gearbox 24, a knurled wheel 25 being provided to drive the gearbox 24 (gearwheel), which is operated from the outside by the user P via a recess in the headphone shell housing 10 or in particular in the ear cushion support 12 can. On the elements 22, here four elements with short circular sections, as well as on the actively movable thrust element 23 and the interruption of the otherwise circular guide 13 visible in FIG. 5b

(Fixation point 14) is the circumferential ear pad 2, preferably formed from one

encased foam, in particular a shape memory foam, attached,

glued on, for example.

The interruption 21 of the ear pad 2 is formed between the fixing point 14 and the end of the actively movable push element 23 adjoining it. By operating the knurled wheel 25 by the user P, the pushing element 23 can now be moved in the pushing direction X. The direction of rotation is counterclockwise. 5b, the pushing element 23 moves in the direction of the fixing point 14, that is to say the opening width of the interruption 21 of the ear cushion 2 fixed thereon is reduced, and consequently the

Ear pads 2 are stretched along the spaces provided there between the fixing point 14, the four displaceable elements 22 and the adjoining pushing element 23. Since between the fastenings on the sliding elements 22 and the

Fixing point 14 are provided on one side and the thrust element 23 on the other side, these spaces are provided, the expansion of the foam of the ear pad 2 can be evenly distributed over this area.

If, conversely, the knurled wheel 25 is turned in the thrust direction X, the opening width of the interruption 21 is enlarged and the ear pad 2 is compressed or upset in the area between the thrust element 23 and, in a further clockwise direction, the four displaceable elements 22 and finally the fixation point 14. This movement and compression also takes place in a distributed manner in the spaces between the fixing point 14, the individual four displaceable elements 22 and the pushing element 23.

The width of the interruption 21 in the ear pad 2 can thus be adapted by the user P via the knurled wheel 25 to the glasses G with the glasses temples T that are being worn. Since the gear mechanism 24 is self-locking, a selected setting remains in place until a conscious adjustment is made using the knurled wheel 25. Alternatively, a lock for the movable thrust element 23 can also be provided.

In a further development of the headphone cup 1, the position of the interruption 21 of the

Ear cushion 2 possible by rotating the ear cushion carrier 12 on the transducer housing 11. This is in the embodiment shown here

Headphone shell housing 10 in plan view circular shaped so that a rotatable Guiding around the axis of rotation D is easy to implement. In the embodiment shown here, a plurality of locking positions are provided in the sound transducer housing 11 on the edge of the ear pad 12 in accordance with the plan view shown in FIG. 5c, into which the ear pad support can be inserted or via a

Rotary guide is adjustable. For example, the locking positions can also be generated magnetically.

Thus, with the headphones 100 according to the illustrated embodiment, any

Headphone shell 1 set the width of the interruption 21 of the ear pad 2 and set the angular orientation of the interruption 21 relative to the headphones 100 so that the position and width of the interruption 21 are optimally adapted to the respective user P with his glasses G and those resting on his ears Temples T is set. This avoids undesirable pressure being exerted on the temples T by the attached headphones 100, which means that even long-term use of the headphones does not lead to impairments and pain for the user. Furthermore, a deposition of the glasses on the bridge of the nose of the user is counteracted, since contact between the ear pad and the temple is reliably avoided. The glasses can thus be worn on the nose in a perfectly customized orientation for the user.

Furthermore, the individual and precise setting of the width of the interruption 21 realizes largely closed headphones, that is to say shielding of external noises, which enables the user to experience the most undisturbed audio possible.
