Description

Technical area

The invention relates to devices for emitting sound, namely to headphones or headphones, and can also be used in the design of ear protectors.

Prior art

There are various designs of headphones, equipped with structural elements for fixing them on the user's head with the ability to select and adjust the position.

Known helmet, containing a hat made of mesh fabric, a tape framing the perimeter of the cap, and anti-noise headphones installed under the tape and containing a cup, elastic sealing rollers, porous sound-absorbing material (see RU 64483 U1).

The well-known helmet has a one-piece mount with antinoise headphones, which eliminates the use of headphones separately from the helmet, for example, in conjunction with a hard headband.

Famous headphones include: two headphone housings, a headband having a through hole at each far end; and two latches inserted into the through holes of the casing of each of the two headphone housings and the through holes of said headband, for fastening said headphone housings to said headband (see RU 64422 U1).

The disadvantages of the known solutions are the limited possibilities of adapting the plane of the earpiece to the surface of the head due to the presence of a hard, by means of a latch, the connection of the headband with the earphone, and the impossibility of using headphones with a helmet or soft headband.

A known design of the mounting of the earpiece as part of a personal acoustic system, comprising: a headband comprising a first mounting support; a headset containing a second mounting support that contains a circular mounting surface; and an elastomeric ring gasket that flexibly connects the headband to the earphone, while the elastomeric ring gasket is located between the first mounting support and the second mounting support, while the elastomeric ring gasket contains an internal mounting surface that is located around the circular mounting surface for connecting the elastomeric ring gasket to the earphone (see RU 2657691 C1).

A disadvantage of the known solution is the complexity of the design, as well as the impossibility of universal use in conditions that exclude the presence of a headband, for example, in conjunction with a helmet, helmet or other headgear.

The most common and closest solution - the prototype is an earphone that contains a sink, fitted on the sides with cylindrical projections for connecting to a rigid headband, implemented, for example, as described, for example, in the decision on RU 160395 U1.

A disadvantage of the known solution is the impossibility of its use with other types of holders in addition to a hard headband, which excludes the possibility of its use, with a soft headband under a hat, for example, with a helmet or helmet, having a design that does not provide for appropriate fasteners, or with a different headdress.

This disadvantage limits the scope of the known solution.

Summary of the Invention

This result is achieved by the fact that in an earphone containing a sink, provided with cylindrical projections on the sides for connection with a rigid headband, said shell is provided with eyelets arranged along the edge for connection with a soft headband.

In addition: - the width of the eyelet corresponds to the width of the fastening tape of the soft headband,

- cylindrical protrusions mounted on the front and rear sides of the shell,

- the eyelets are installed on the top and rear sides of the shell.

Technical task

The technical result is the expansion of the field of application due to the possibility of using headphones with both a hard spring headband and a soft headband.

The positive effects of the invention

The headset has a wider scope as it can be used not only with a hard headband, but also can be fixed on a soft headband, for example, for use with a helmet, the design of which does not include special headband mounts or with a different head-fitting helmet.

Description of embodiments

For the left and right ear, the left and right earphone are designed, respectively. Left headphone FIG. 1), as well as the right one (Fig. 3), contains a shell made of plastic, fitted with cylindrical protrusions on the sides for connection with a rigid headband. At the edge of the shell there are also at least two eyes for fastening with a tape on the soft headband. At the same time, the width of the eyelet corresponds to the width of the fastening tape of the soft headband. On the inside of the earpiece there is an ear cushion made of elastic material.

The appearance of the earpiece is characterized by the presence of a sink or cup with an oval profile and a convex outer side with a horizontally oriented projection of the power compartment in the lower part of the outer side of the shell, where the controls buttons are also located. On the front side of the shell, in the recess, there is a microphone jack, also on the front and rear sides there are cylindrical protrusions for attaching to a hard headband. On the top and back sides of the shell there are eyelets for attachment to a soft headband.

The shape of the earpiece is a complex volumetric shape, characterized by the presence of a rigid convex shell, on the outside, and a soft ear cushion on the inside. The left and right headphones are mirror-symmetrical in shape, with the exception of the absence of an eyelet on the right earphone for mounting the cap, buttons for the controls and one of the two tubular cable leads. The compositional solution of the earphone has a sufficiently artistic informational expressiveness, creating a clear image and informing about its specific purpose.

The headset is used as follows.

Both hard and soft headband uses two headphones: left and right, mounts which are mirror symmetrical to each other.

When using the earpiece in the composition with a rigid spring headband, cylindrical projections on the side walls of the shell are used as fasteners. At the same time, the corresponding cylindrical holders are installed on the said protrusions, in the holes on the other side of which a curved rod is mounted, fastened directly to the spring headband.

The connection of a rigid headband with a cylindrical protrusion may have various design options, the general feature of which is the presence of a hinged connection between the earphone and the headband, which allows to adapt the plane of the ear cushion to the surface of the user's head.

The earphone installed in this way allows you to adjust the mounting height on the holder shaft, and also thanks to the hinged connection, part of which is a cylindrical protrusion, the earphone has the ability to change the angle of the plane of the ear cushion to ensure a snug fit to the user's head or auricle.

If it is necessary to use a headset together with a helmet or a helmet, equipped with the appropriate fasteners in the form of runners or “rails”, cylindrical shell lugs are also used, on which fastenings are worn, forming a hinged connection of the earphone with the helmet.

The assembled mount is mounted on the corresponding protrusions of the helmet from its outer side and secured in a user-friendly position.

A headset mounted on both a hard headband and mounted on a helmet has the ability to adaptively change its position relative to the surface of the head, so that the headset fits snugly and covers the user's ear.

To use a headset with a helmet that does not have special mounts, or with a different headgear, use a soft headband, for example, made of netted fabric, which has straps in the form of webbing, at the place where the earphone is attached. These straps are threaded into the corresponding lugs of the earphone and secured by interconnecting the parts of the tapes provided with velcro on the ends. Adjusting the position of the earpiece by moving it on the clip

The left and right headphones in the composition of the soft headband, thanks to the tight girth of the head, are securely held together with the fabric headband under a helmet or other headgear.

The number of lugs corresponds to the number of straps. In the example shown in FIG. 5, the earphone body has three lugs, two of which provide for holding the earphone in a vertical plane and are made on the edge of the upper side of the shell, and one eye in the lower back part of the side, ensuring retention in the horizontal plane.

The places where the lugs are made on the edge of the shell are maximally separated from each other, providing the possibility of adaptive orientation of the earpiece depending on the anatomical features of the user's head and, thus, tightly pressing the earphone to the ear without gaps

The operation of the earpiece is controlled by acting on the control buttons located on the lower side of the shell of the left earpiece. This arrangement of controls provides ease of use of an earpiece attached to the head under a helmet or other headgear, since access to the buttons remains free without the need to remove the helmet.

The protruding part of the battery compartment is equipped with a lid, which, thanks to this protrusion, allows you to find the battery compartment lid and change the battery with one hand, also without having to remove the helmet and headband earpiece.

Due to the presence on the headphone case of cylindrical projections together with eyelets, the earphone has a versatility that makes it possible to use it both with rigid mounts, comfortable in a fixed workplace setting, and with soft mounts — soft headbands, which can be used with a headgear, for example, with a helmet , when working in dangerous or difficult conditions. The presence of such versatility provides an extension of the scope of the earpiece.

When using the earphone only as a passive anti-noise protection, the earpiece may not provide for the presence of a sound-emitting element and corresponding electrical connections with external devices.

A sound emitter built into the case of the earpiece sink - a speaker allows realizing the function of active noise suppression and / or providing a hardware connection of the user with a remote point of contact.

The headset can be used with a built-in microphone, which provides the perception of user messages for further processing. A built-in microphone with an appropriate wired shell can be installed on the front side wall of the sink.

In addition, a remote microphone can be installed in the external microphone jack. In the absence of a remote microphone, the connector is closed with a special plug, held by means of a flexible connection on the eyelet for fastening the connector plug.

The tubular leads of the connecting wires are used to lead the wires out of the headphone casing. At the same time, the left earpiece has two such outputs: one for connection with external equipment and the second for connection with devices of the right earpiece, and the right earpiece has only one tubular outlet for outputting the wire of the connection with the left earpiece.

The above description contains specific embodiments of a technical solution, which are merely illustrative, and do not limit the implementation of the solution, which can be implemented in other ways.

Industrial Applicability
