Technical Field

[0001] The utility model relates to the technical field of ear-hanging earphones, in particular to a 360-degree rotating earphone. Background Art

[0002] Ear-hook headphones are headphones that are designed to be fixed on the ears rather than inserted into the ear canals. They are not easy to fall off during strenuous exercises such as running and jumping. Existing ear-hook headphones are straight-hook designs, and the angle between the ear hooks and the headphones cannot be adjusted. However, due to differences in ear size and wearing habits of wearers, the non-adjustable ear hooks affect the wearer's use of the headphones. In order to solve the problem of ear hook angle adjustment, a new type of 360-degree rotating headphones is needed. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-5 The 360-degree rotating earphone shown comprises an earphone inner shell 1, an earphone outer shell 2 is arranged on the front of the earphone inner shell 1, a playback unit 3 is arranged in the inner cavity of the earphone inner shell 1 and the earphone outer shell 2, and an ear hook 4 is arranged on the side of the earphone inner shell 1;

[0020] It should be noted that the earphone inner shell 1 and the earphone outer shell 2 are fixed by glue, the reference model of the playback unit 3 is the working principle of GD-31, a sound transmission port 102 is provided on the top of the inner wall of the earphone inner shell 1, and the transmission port 102 is used to transmit the sound of the playback unit 3, and the ear hook 4 is made of plastic, which is light and easy to shape, and the plastic material is easy for users to clean and maintain;

[0021] A rotating member 5 is provided at the connection between the earphone inner shell 1 and the ear hook 4;

[0022] Specifically, the rotating member 5 includes a positioning column 501 disposed at the end of the ear hook 4, the end of the positioning column 501 is inserted and connected to the outside of the earphone inner shell 1, and the end of the positioning column 501 is inserted and connected to the inner cavity of the earphone inner shell 1 with a fastening bolt 503;

[0023] It should be noted that a cylindrical hole for inserting the positioning column 501 is provided on the outer side of the earphone inner shell 1, and the cylindrical hole is connected to the inner cavity of the earphone inner shell 1. The positioning column 501 is made of plastic material, and it is integrally injection molded with the ear hook 4. A threaded hole for inserting the fastening bolt 503 is provided in the inner cavity of the positioning column 501. The diameter of the end of the fastening bolt 503 is larger than the diameter of the cylindrical hole, so that the position of the positioning column 501 and the earphone inner shell 1 is limited;

[0024] A damping part for buffering the rotation of the positioning column 501 is provided on the outer side of the positioning column 501;

[0025] Specifically, the damping part includes a movable groove 101 arranged on the inner wall of the earphone inner shell 1, a compression spring 504 is arranged inside the movable groove 101, a gear 502 is sleeved on the outer side of the positioning column 501, and a clamping wheel 505 for preventing the gear 502 from rotating is arranged at the end of the compression spring 504;

[0026] It should be noted that a limiting protrusion 5051 is provided at the top of the card wheel 505 and in the middle of the compression spring 504. The card wheel 505 is made of plastic material, and it and the limiting protrusion 5051 are integrally injection molded. The limiting protrusion 5051 is used to limit the deformation direction of the compression spring 504. The compression spring 504 drives the card wheel 505 to insert into the side of the gear 502, thereby playing a damping role on the rotation of the gear 502.

[0027] Specifically, a locking protrusion 5021 is symmetrically arranged in the middle of the gear 502, and a locking groove 5011 for the locking protrusion 5021 to penetrate is symmetrically arranged on the outer side of the positioning column 501;

[0028] It should be noted that the diameter of the end of the fastening bolt 503 is larger than the diameter of the middle cross-section of the gear 502, so that the fastening bolt 503 limits the insertion distance of the gear 502 into the positioning column 501, thereby preventing the gear 502 from being separated from the positioning column 501, and the cross-sectional diameter of the gear 502 is larger than the diameter of the cylindrical hole on the outer side of the earphone inner shell 1, thereby limiting the position of the gear 502;

[0029] The gear 502 and the locking protrusion 5021 are both made of plastic and are integrally injection molded. The locking groove 5011 is a rectangular groove. The locking protrusion 5021 and the locking groove 5011 are interlaced and fixed, so that the gear 502 and the positioning column 501 become a whole and rotate synchronously, thereby achieving the rotation damping restriction of the ear hook 4 connected to the positioning column 501 by the clamping wheel 505;

[0030] The inner wall of the earphone inner shell 1 is symmetrically provided with a limit strip 6 located on the side of the gear 502. The inner wall of the earphone inner shell 1 is provided with a rectangular groove for placing the limit strip 6. The placement of the limit strip 6 isolates the playback unit 3 from the rotating member 5 to prevent the rotation of the rotating member 5 from affecting the normal operation of the playback unit 3.

[0031] During actual use, when wearing the earphones, the user rotates the ear hook 4 to the desired angle. During the rotation, the compression spring 504 in the rotating component drives the card wheel 505 to insert into the tooth groove of the gear 502, and the card wheel 505 retracts and resets in the tooth groove of the rotating gear 502, thereby buffering the rotation of the positioning column 501. This design allows the earphones and the ear hook 4 to achieve 360-degree rotation through the positioning column 501. Compared with other direct-hanging earphones, the earphones can rotate the ear hook 4 to an angle that matches the wearer, thereby adapting to the wearer's ears and avoiding the unadjustable angle of the ear hook 4.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
