[0002] Bluetooth headphones include in-ear Bluetooth headphones, open-back Bluetooth headphones, and semi-in-ear Bluetooth headphones. In-ear Bluetooth headphones achieve a secure fit through a structure that adapts to the ear canal, while open-back and semi-in-ear Bluetooth headphones typically achieve a secure fit through an ear hook structure.

[0003] In the prior art, Chinese utility model patent application number CN202321526154.5 discloses a hook-type vertical charging ear-hook Bluetooth headset, including a charging shell, a sealing cover, an earphone charging mechanism, and an external charging mechanism. This hook-type vertical charging ear-hook Bluetooth headset, by having two ear hooks overlap and hang vertically on the ear hook crossbeam, effectively reduces the space occupied by the two ear hooks, thereby reducing the volume of the charging case and the overall size of the device, saving production costs, and making it more convenient for daily carrying.

[0004] However, the ear-hook Bluetooth headphones provided by the aforementioned patent rely solely on the connection between the ear hook and the ear for wearing, resulting in an unstable fit. Furthermore, the ear hook's structural design is unreasonable, being too short and ergonomically unsuitable, leading to extremely low wearing comfort. After prolonged use, the user experiences noticeable pain due to the ear being pinched. Therefore, it is necessary to design new headphones to address the problems existing in the current technology.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The preferred embodiment of the Bluetooth headset of this utility model, such as Figure 1-7 As shown, the device includes an earphone body, which includes a sound-releasing body portion 10 for placement within the concha cavity, a longitudinally extending portion 20 located at the upper end of the sound-releasing body portion 10, an ear hook portion 30 that bends backward and downward at the upper end of the longitudinally extending portion 20, and a charging case body portion 40 located at the lower end of the ear hook portion 30; wherein, the diameter of the ear hook portion 30 is smaller than the diameter of the charging case body portion 40, and the sound-releasing body portion 10 has an elliptical structure with a left-right diameter smaller than its front-back diameter.

[0033] Furthermore, the front side of the end of the sound-emitting body 10 facing the human ear is provided with a speaker hole 50, and the charging body 40 is arranged in the front-back direction and located below the sound-emitting body 10; the longitudinal extension 20 is located at the end of the sound-emitting body 10 away from the human ear, the lower end of the ear hook 30 is inclined and tilted towards the side of the human ear, and the charging body 40 is located on the side of the sound-emitting body 10 facing the human ear; when assembled in place, the upper ends of the charging body 40 and the sound-emitting body 10 respectively form two stepped positions 60. In use, the lower step 60 corresponds to the charging case 40, which fits against the back of the ear, while the upper step 60 corresponds to the sound release body 10, which extends into the concha. The cooperation of the two steps 60 ensures the fit between the sound release body 10 and the concha, while also preventing the longitudinal extension 20 from squeezing the helix and tragus. This ensures that the longitudinal extension 20 and the sound release body 10 are in a suitable fit, resulting in a moderate tightness and significantly improving wearing comfort. In addition, the specific shape design of the lower end of the ear hook 30 tilting towards the ear and the positioning design of the charging case 40 along the front-back direction further improves the fit with the skin behind the ear and enhances the overall stability of the earphone body on the ear.

[0034] In this embodiment, the ear hook 30 is arc-shaped with its convex surface facing backward. The ear hook 30, the longitudinal extension 20, and the charging case body 40 together form a semi-circular ear fitting cavity 70 to fit the arc-shaped contour of the back of the ear and ensure the comfort of the ear hook 30 after wearing. Furthermore, the lower front end of the ear fitting cavity 70 has a receiving gap 80 to avoid the earlobe, so that the lower end of the charging case body 40 extends into the back of the ear, thereby improving the fit between the ear hook 30 and the back of the ear. At the same time, since the outer surface of the charging case body 40 is larger, the contact area between the charging case body 40 and the back of the ear is also large enough, dispersing the clamping pressure of the ear hook 30 on the back of the ear and avoiding excessive clamping of the ear hook 30 on the earlobe, further promoting wearing comfort.

[0035] In this embodiment, both the longitudinal extension 20 and the charging case body 40 are cuboid structures, and each of their edges is provided with a rounded chamfer to further improve wearing comfort, avoid the abruptness of the edges, and ensure that there is no discomfort caused by excessive local pressure during long-term wear. In addition, the elongated design of the longitudinal extension 20 and the charging case body 40 also makes it easier to design the main control board 90 and the battery 100 as elongated shapes (the elongated main control board 90 is conducive to the distributed arrangement of electronic components, especially for some long resistors, which can be installed in a flat and attached manner), so that the overall shape of the earphone body is streamlined with a smaller diameter. Compared with the design of installing the battery 100 in the sound release body 10, which would result in a larger overall width and an abrupt feeling, the appearance and wearing comfort are further improved. Moreover, designing the charging case body 40 on the lower part can also make the center of gravity lower after wearing, further improving the stability of the earphone body when wearing.

[0036] In this embodiment, the ear hook 30 is cylindrical and has transition sections 31 at both its upper and lower ends with diameters that gradually increase in the opposite direction to each other, so as to further improve the comfort of contact with the back of the ear after wearing.

[0037] In this embodiment, the longitudinal extension 20 has a recess 21 on the side wall facing the ear, and the recess 21 is recessed in the direction away from the ear. Specifically, the longitudinal extension 20 is arc-shaped and its convex surface faces away from the ear, and the concave surface of the longitudinal extension 20 forms the recess 21. Furthermore, the recess 21 has a conductive contact terminal 110 for charging in contact with the charging terminal of the battery compartment base, and also has a marking area 120 (marking whether the earphone body is worn on the left or right ear). The design of the recess 21 not only avoids squeezing the helix and tragus when wearing, but also allows the gap between the recess 21 and the helix and tragus to be used to install the charging copper post, effectively avoiding the discomfort caused by the unevenness of the copper post and the marking to the helix and tragus.

[0038] In this embodiment, the sound release body 10 and the battery compartment body 40 are detachably connected to the ear hook 30 for easy separate manufacturing; furthermore, the sound release body 10 has a speaker, the longitudinal extension 20 has a main control board 90, and the battery compartment body 40 has a battery 100; the ear hook 30 has a wire channel passing through both ends; the wire in the wire channel is integrally injection molded with the ear hook 30.

[0039] To facilitate assembly and processing, the sound-emitting body 10, the longitudinal extension, and the power compartment body 40 all adopt a detachable double-shell design. The sound-emitting body 10 includes a first bottom shell 101 and a first sealing plate 102 that are opposite each other in the left-right direction. The first sealing plate 102 is used to seal the opening of the first bottom shell 101. The longitudinal extension is located on the upper part of the end of the first bottom shell 101 away from the first sealing plate 102 and the two are integrally injection molded. The sound-emitting hole is located at the front end of the side wall of the first sealing plate 102 away from the first bottom shell 101. The first bottom shell 101 and the first sealing plate 102 are both circular, and the cavity between them is used to fix the loudspeaker.

[0040] The longitudinal extension 20 includes a second bottom shell 201 and a second sealing plate 202 arranged opposite each other in the left-right direction. Both the first bottom shell 101 and the second bottom shell 201 are rectangular and arranged longitudinally. The lower end of the second bottom shell 201 is fixed to the upper back of the first bottom shell 101. A recess and a copper pillar are both provided on the side wall of the second bottom shell 201 facing away from the second sealing plate. The second sealing plate 202 is used to seal the opening of the second bottom shell 201, and the two together form a mounting cavity for mounting the main control board 90. The second bottom shell 201 and the second sealing plate 202 are connected to the ear portion by a snap-fit ​​connection. Specifically, a [missing information - likely a design feature] is provided at the center of the upper end face of the ear portion 30. The columnar boss 32 has an annular positioning part 33 on the peripheral wall at its end. The diameter of the annular positioning part 33 is larger than the diameter of the columnar boss 32, so that a positioning gap is formed between the annular positioning part 33 and the end face of the ear. After assembly, the end faces of the second bottom shell 201 and the second sealing plate 202 are pressed against the end face of the ear. Correspondingly, the wire connecting the main control board 90 and the battery coaxially passes through the end face of the columnar boss 32, and there is a positioning groove 2a on the upper inner wall of the second bottom shell 201 and the second sealing plate 202 for positioning the annular positioning part 33. When the two positioning grooves 2a are closed, the annular positioning part 33 is locked in the mounting cavity.

[0041] Furthermore, to facilitate the separate injection molding of the second bottom shell 201 and the second sealing plate 202, a protruding wall 2b facing the second sealing plate 202 is provided on the edge of the second bottom shell 201. A fixing groove 2c for the protruding wall 2b to be inserted is provided on the inner side wall of the second sealing plate 202. A protruding buckle 2d is provided at the center of the inner wall of the fixing groove 2c. A slot b1 that matches the protruding buckle 2d is provided on the outer side wall of the protruding wall 2b. After assembly, the second bottom shell 201 and the second sealing plate 202 are firmly snapped together by the cooperation of the two protruding walls 2b on the front and rear sides of the upper end of the second bottom shell 201 and the two slots b1 on the second sealing plate 202. In order to prevent the lower ends of the second bottom shell 201 and the second sealing plate 202 from separating, the lower ends of the two are also connected by the same connection method.

[0042] Furthermore, in order to further increase the stability of the assembly process of the second bottom shell 201 and the lug, and to ensure the stable progress of the next assembly process, one side wall of the protruding wall 2b is designed as one side wall of the positioning groove 2a. After the annular positioning part 33 is assembled, the side wall of the protruding wall 2b abuts against the end face of the columnar boss 32. At this time, it can cooperate with the positioning groove 2a to improve the stability of the second bottom shell 201 and the lug after assembly, making it easier to move the two as a whole, and facilitating the assembly of the main control board and the second sealing plate 202 in the next process.

[0043] In addition, in order to reduce the radial sway between the lug and the second bottom shell 201, the peripheral sidewall of the annular positioning part 33 is designed as a slope with its larger end facing the direction of the protruding wall 2b.

[0044] Furthermore, due to the small overall size of the headphones, the volume of the protruding wall 2b is also smaller. In order to ensure the structural strength of the connection of the protruding wall 2b, multiple protruding ribs b2 are integrally provided on the inner sidewall of the protruding wall 2b, and these multiple protruding ribs are arranged side by side; and a connecting post 2e that can be inserted into the edge of the second bottom shell 201 is further provided on the second sealing plate 202.

[0045] Specifically, the electrical compartment body 40 includes a third bottom shell 401 and a third sealing plate 402. The opening direction of the third bottom shell 401 and the third sealing plate 402 is the same as that of the second bottom shell 201 and the second sealing plate 202. In order to facilitate the structural design of the injection mold, the connection method of the third bottom shell 401 and the third sealing plate 402 is the same as that of the second bottom shell 201 and the second sealing plate 202. The connection method between the third bottom shell 401 and the third sealing plate 402 and the hanging ear is also the same as that between the second bottom shell and the second sealing plate 202 and the hanging ear. That is, the lower end face of the hanging ear also has another columnar boss in the center. The end peripheral wall of the columnar boss also has an annular positioning part. Correspondingly, the third bottom shell and the third sealing plate have a connection structure adapted to the annular positioning part.

[0046] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
