Description

FIELD OF TECHNOLOGY

The invention relates to constructions of devices for emitting sound, more specifically, to designs of headphones.

BACKGROUND OF THE INVENTION

There are various designs of headset headsets designed to adjust the position of the headphones relative to the headband and secure the headphones in the selected position.

Known application US 2014205129, publication 07.24.2014, IPC H04R 1/105, which disclosed the design of the headset headphone, which provides the adaptation of the headphone to the user's ears. The adjustment mechanism includes a headphone holder, to which a bar with a slot is attached to the hinge along which the enclosing element slides. This adjustment allows the headphone to move vertically. This adjustment mechanism allows you to easily adjust the position of the headphone phones by moving the bar with a slot in the holder. However, this design does not allow the holder to rotate in the transverse plane for finer adjustment. In addition, the fixation of the holder strip can easily be changed. Therefore, you often have to adjust the headphones when re-dressing.

Known patent US 1503908, publication 05/08/1924, which disclosed the design of the headset headphone, in which a flexible headband is attached a round rod on which the screw is attached to the phone holder. The phone holder in the process of adjustment can move around the shaft, and also rotate around the shaft at the desired angle. In this design, it is possible to adjust the headphone phones in any position. However, the phone holder can be rotated at any angle around the rod, which is also inconvenient. To achieve a convenient setting, it is necessary to spend a lot of time, since the rotation of the headphones, which, as practice shows, requires not a small angle, is possible by 180 degrees in this design. In addition, due to the small diameter of the rod to which the holder is attached, the fastening is not very reliable.

Closest to the claimed invention is the design of a headset headphone according to patent US 1167368, publication 04.01.1916. The headset includes a flexible headband, telephone holders and mechanisms for adjusting and securing the holders on the headband. In this case, the holder (Fig. 4, 5) contains a bar with a slot through which, using the screw shaft (17), the bar is moved in the longitudinal direction relative to the headband during adjustment and secured by the screw (17) in this position. Another mechanism allows you to adjust the position of the phones in the transverse plane with the screw (15 '). Thus, in order to adjust the position of each headphone phone, you must first adjust it in one plane and fix it with one screw, then adjust it in another plane and fix it with another screw.

SUMMARY OF THE INVENTION

The technical result of the claimed invention is the creation of a headset headphone, which provides the convenience of adjusting and fixing the headphone phones in a position defined by the user, as well as increased reliability of both fixing in the selected position, and the reliability of the whole structure as a whole during operation.

The headset includes a headband with a flexible bow, phone holders and mechanisms for adjusting and securing the holders on the headband. Each adjustment and fixing mechanism comprises a base with a recess fixed at the end of the headband bow. The holder includes a strip, on one side made concave, on the other side convex, a slot is made in the middle of the strip, the holder strip with the convex side is placed in the recess of the base. The fastening element with a convex surface and a hole is located in the concave side of the holder bar. The clamping element includes a rod passing through the aforementioned hole of the fastening element and a slot in the holder strip and fixed to the base. The diameter of the rod of the clamping element is less than the width of the slot of the holder bar. The holder bar in the adjustment process is installed in the recess of the base with the possibility of movement in the longitudinal plane and rotated in the transverse plane, and the clamping element is made with the possibility of pressing the holder bar to the base by means of the fastening element in the position selected during the adjustment.

Thus, it is possible to adjust the position of each headphone phone in the longitudinal direction of the holder along the slot and to rotate the phone in the transverse plane due to the gap between the clamping member rod and the side walls of the slot of the holder strip. In addition, it provides reliable fixation of the phone in the selected position due to the design of mechanisms for adjusting and securing the holders on the headband. Reliable fastening is ensured by a sufficiently large contact area of the convex side of the holder strip in the recess of the base and the convex side of said strip and the concave side of the strip and the convex surface of the fastener. A headset with such an adjustment mechanism has the reliability of the entire structure due to the reliability of each element and the resistance to bending of the entire structure.

In particular, the holders can be made with a fork-shaped bracket, the ends of which are mounted phones.

In addition, the recess of said base can be made in a semicircular cross section and the outer and inner sides of said holder bar in a cross section of a semicircular shape. The fastener may also have an approximately semicircular sectional shape of a convex surface.

In particular, the clamping element is made in the form of a screw made with the possibility of screwing into the base.

In addition, soft support can be fixed below and coaxially with a flexible headband. This support more accurately captures the headband on the user's head and creates additional soft support. Therefore, when re-using the headset, the headset is set more precisely to the selected position.

MODES FOR CARRYING OUT THE INVENTION

The headset (Fig. 1, 2) includes a headband with a flexible handle 1 and soft support 17, holders 2 of phones 3 and mechanisms for adjusting and securing the holders 2 on the headband. The phone holder 2 (Fig. 2) contains a bracket 15 with mounts 16 of the phones 3, made in the form of pins and a strap 6, which is an element of the holder 2 and an integral part of the mechanism for adjusting and securing the holders 2 on the headband.

The adjustment and fixing mechanism includes a strip 6 of the holder 2 (Fig. 3 - 5), which is concave 7 on the one hand and convex 8 on the other. In the cross section (Fig. 4), the surfaces 7 and 8 can be made close to the shape of the segments circle. This embodiment of the strip 6 can be performed, in particular, by stamping. Each adjustment and fixing mechanism also includes a base 4 (Fig. 6) with a recess 5, mounted on the end of the headband 1 bow by means of grooves 20. A hole 19 with a thread is made in the recess of the base. The recess 5 in cross section can be made in the form of a segment of a circle.

An element of the adjustment and fixing mechanism is also (Fig. 7) a fastening element 10, with a convex surface 11 (circle segment in cross section) and a through hole 12.

The clamping element of the mechanism in the most effective embodiment of the design of the headset is a screw 13 (Fig. 8) with a threaded rod 14. The clamping element can be made in different ways. For example, in the form of a cam clamp (not shown in the figures). In this case, the cam clamp shaft is fastened to the base 4, and the cam rests on the surface 25 of the fastener 10 during rotation.

For the design of the headset is important, the ratio between the diameter of the rod 14 of the screw 13 (clamping element), which should be less than the width of the slot 9 of the strap 6 of the holder 2. The wider the slot 9 with respect to the diameter of the rod 14, the larger the angle of the strap 6 holder 2. However, with a large ratio between the width of the slot 9 of the strip 6 and the diameter of the rod 14, the reliability of pressing the adjustment and fixing mechanism decreases.

The adjustment and fixing unit is shown in FIG. 9. The base 4, which is fixed at the end of the headband bow 1, has a recess 5 in which the bracket 6 of the holder 2 is placed on the convex side. On the other concave side 7 of the bracket 6, an attachment element 10 with its convex 11 side is placed. The rod 14 of the screw 13 (clamping element), passing through the hole 12 of the mounting element 10 and the slot 9 of the strap 6 of the holder 2, is screwed into the threaded hole 19 of the base 4 (Fig. 10).

The strap 6 of the holder 2 together with the telephones 3 can be moved in the longitudinal plane during the adjustment process, the slot 9 of the strap 6 moves along the shaft 14 of the screw 13. In FIG. 11 shows the downward movement (24) of the strip 6 of the holder 2, FIG. 13 up 21. The bar 6 can be rotated clockwise 25 (Fig. 12) and counterclockwise 24 (Fig. 13) from the middle position to the position until the shaft 14 of the screw 13 abuts against one of the side surfaces 18 of the slot 9 of the bar 6 .

The holder 2 is fastened in the desired position by pressing the screw 13 against the surface 25 of the fastening element 10, which in turn presses the bar 6 against the base 4
