Description

Technical Field

[0001] The invention relates to the technical field of headphones, and in particular to a headphone capable of automatically fitting a face shape. Background Art

[0002] Earphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using a speaker close to the ear. Headphones are different from in-ear earplugs. Because the sound-generating part of the earphones does not enter the ear, they have the advantages of good sound field, high comfort, and avoidance of scratching the ear canal. In recent years, more and more people like them. At present, the headsets seen on the market have the earmuffs that directly cover the outside of the ears and directly squeeze the face when the user uses them. The user rotates the ear cups to fit the user's face, but the earmuffs cannot maintain a good fit with the face for a long time, especially when the user is active. When using this type of headset for a long time, the ears and face will feel pain or discomfort due to long-term squeezing.

[0003] To this end, Chinese invention patent CN103945296B provides a headset, including a headband body, a hanger body, a hinge body arranged at both ends of the headband body for connecting the hanger body, and an ear cup body connected to the hanger body, the hinge body includes a hinge swing shaft and a hinge cover sleeved on the hinge swing shaft, the hinge swing shaft includes an axis, a corrugated spring sheet, a friction sheet, and a swing shaft lower bracket connected to the hanger body and a swing shaft upper bracket connected to the headband body; the upper end of the axis is sleeved with a corrugated spring sheet, a friction sheet and a swing shaft lower bracket in sequence, and connected to the swing shaft upper bracket, the corrugated spring sheet, the friction sheet and the swing shaft lower bracket abut against each other and can rotate around the axis, and the user can adjust the earmuff body to fit the user's face shape after wearing the headset. However, the above scheme has the following disadvantages:

[0004] (1) The structure of the hinge body is complex. The ear cup body is rotated around the swing axis to an angle that fits the user's face shape by abutting against each other through the corrugated spring sheet, the friction sheet, and the bracket under the swing axis. When in use, the ear cup cannot automatically fit the user's face shape and needs to be manually adjusted by the user, which is cumbersome to operate.

[0005] (2) The rotation of the swing shaft is limited by the mutual contact between the corrugated spring sheet and the friction plate. As the use time increases, the gap between the corrugated spring sheet, the friction plate and the swing shaft may increase or the corrugated spring sheet may deform, resulting in limit failure, causing the ear seat body to rotate randomly, causing the position of the ear seat body to change, and failing to fit the user's face shape in real time, resulting in a reduction in its service life.

[0006] In view of this, there is an urgent need to improve the existing headphone structure that fits the face shape, so as to simplify its structure, automatically fit the user's face shape, and extend its service life. Summary of the invention

A spring clamp (not shown in the figure) is arranged in the clamping groove 216. The spring clamp sleeve is arranged on the swing shaft 42 to limit the swing shaft 42 in the swing shaft groove 431.

[0046] The working process of the present invention is as follows:

[0047] When the user wears the earphones, the earphone body 2 needs to fit the user's face shape. The paddle 41 drives the swing shaft 42 to swing in the swing shaft groove 43, and adjusts the earphone body 2 to an angle suitable for the user's face shape, so that the earphones are automatically adjusted to fit the user's face shape when the user wears the earphones, without the need for separate adjustment before wearing.

[0048] The sound unit of the earphone body 2 is detachably arranged on the bracket 21. A rotating shaft 212 is arranged on the connecting arm 211 of the bracket 21. When the ear shell 221 rotates to the position where the limiting protrusion 213 on the rotating shaft 212 coincides with the limiting groove 224, the connecting arm 211 is opened outwardly, the plug 215 on the limiting protrusion 213 is separated from the plug socket on the generating assembly 222, and the rotating shaft 212 is pulled out from the shaft hole 223, so that the sound unit can be removed from the bracket 21.

[0049] The earphone body 2 is rotatably arranged on the head bow 1 through the rotating assembly 3. When the earphone is in the folded state, the earphone body 2 is opened outward, and the rotating piece 32 is rotated outward until the limiting arc portion 323 abuts against the inner end surface of the connecting groove 333, and the earphone body 2 is in the opened state. When the earphone needs to be folded, the earphone body 2 is folded inward, and the rotating piece 32 is rotated inward until the second connecting ear 322 is inserted into the slot 335, and the earphone body 2 is in the folded state.

[0050] Before the earphone is folded, the ear shell 221 can be turned 180° by the rotating shaft 212 , so that the earmuffs 226 of the folded earphone can be arranged relative to each other to prevent the earmuffs 226 from being worn.

[0051] Compared with the prior art, the headset provided by the present invention can automatically fit the face shape. The headset body and the head bow are connected by a swing structure. The swing structure includes a swing groove arranged on the headset body and a swing shaft and a paddle arranged in the swing groove. When the user wears the headset, the headset body and the head bow rotate relative to each other and automatically fit the user's face shape without the need for the user to make separate adjustments. The present invention has a simple structure, and the swing structure will not fail due to long-term use, and has a long service life.

[0052] In this solution, the swing groove includes a swing axis groove and a paddle groove arranged on both sides of the swing axis groove. There is an angle between the side walls of the paddle groove, which limits the swing angle of the paddle. In this solution, the bracket is made of elastic material, and the swing axis groove is elastic, which can clamp the swing axis and the paddle arranged in the swing axis groove to prevent the paddle from swinging randomly, resulting in the earphone body not being able to accurately fit the user's face shape during use.

[0053] In the present solution, the sound unit is rotatably arranged on the connecting arm of the bracket, a limiting protrusion and a plug are provided on the rotating shaft at the lower end of the connecting arm, a plug socket is provided on the sound component arranged in the ear shell, and a limiting groove matched with the limiting protrusion is provided on the ear shell, and the limiting groove is arranged on the movement trajectory of the limiting protrusion, so that the user can remove the sound component from the bracket conveniently according to the use needs, and replace the sound unit with different parameters and functions to meet the user's use needs in different scenarios.

[0054] The present invention is not limited to the above-mentioned optimal implementation mode.
