Description

Technical Field

[0001] The utility model relates to the technical field of wireless earphone design, in particular to a head-mounted Bluetooth earphone. Background Art

[0002] A head-mounted Bluetooth earphone is a kind of wireless earphone, which is opposite to an in-ear Bluetooth earphone. Its characteristic is that it is worn on the human head through a hoop structure during use. The advantages of the head-mounted Bluetooth earphone are that, on the basis of wireless transmission, it also has the advantages of a head-mounted earphone. For example, when the left and right earphones are used, the human ears are covered therein. Therefore, it has advantages such as good sound field, good sound quality, good comfort, avoiding ear canal abrasion caused by inserting into the ears, and better protection for the eardrums of the ears.

[0003] The defect of the traditional head-mounted Bluetooth earphone is that, during use, the left and right earphones need to be covered outside the human ears, but in fact, the contours of the human head are different, and it is very difficult to achieve a high degree of fit. The traditional solution is to set leather gaskets on the left and right earphones on the basis of the elastic extrusion force provided by the hoop to improve the fit with the human body. However, this kind of traditional design is based on a fixed-shaped frame design. Even with leather gaskets, it is difficult to match the contour of the human body highly. Therefore, it often uses the extrusion force generated by the elastic force to force the leather pad to fit the human body as much as possible, resulting in discomfort for users due to the obvious extrusion force and a decline in user experience. Summary of the Utility Model

[0004] Based on this, the utility model provides a head-mounted Bluetooth earphone, which sets an elastic liquid sac at the earphone body, and uses the deformation characteristics of the elastic sac body to achieve the effects of closely adhering to the human contour and buffering, reducing the discomfort caused by the extrusion force, and improving the user experience.

[0040] As Figures 1 to 10 shown, it is a head-mounted Bluetooth headset 100 of an embodiment of the present utility model.

[0041] As Figure 1 and Figure 2 shown, the head-mounted Bluetooth headset 100 includes: a hoop component 10, and a first earphone component 20 and a second earphone component 30 respectively connected to the hoop component 10. Among them, the hoop component 10 is used to be worn on the human head and plays a fixing role. The first earphone component 20 and the second earphone component 30 are used to play audio.

[0042] Below, in combination with Figures 1 to 10 , the above-mentioned head-mounted Bluetooth headset 100 will be further described.

[0043] In this solution, on the premise of meeting the wearing requirements, the specific structure of the hoop component 10 can be various. Below, an implementation manner of the hoop component 10 is provided.

[0044] As Figure 1 and Figure 3 shown, in this embodiment, the hoop component 10 includes: a U-shaped hoop 11 and a third elastic liquid sac 12 attached to the inner side of the U-shaped hoop 11. One end of the U-shaped hoop 11 is connected to the first earphone component 20, and the other end of the U-shaped hoop 11 is connected to the second earphone component 30. The U-shaped hoop 11 serves as a connection medium between the first earphone component 20 and the second earphone component 30, and plays a positioning and fastening role during wearing, while the third elastic liquid sac 12 contacts the human head and plays a buffering and fitting role.

[0045] Furthermore, as Figure 3 shown, the number of the third elastic liquid sacs 12 can be multiple and evenly spaced along the length direction of the U-shaped hoop 11. The multiple spaced third elastic liquid sacs 12 can share the force, and can also make different initial shapes according to different positions to better adapt to the contour of the human head, and the gap between two adjacent elastic liquid sacs can provide a space for deformation. For example, in this embodiment, the number of the third elastic liquid sacs 12 is two and symmetrically distributed with respect to the midline of the U-shaped hoop 11.

[0046] In addition, to facilitate the adjustment of the positions of the first earphone assembly 20 and the second earphone assembly 30, so as to better adapt to different head shapes, in other embodiments, telescopic joints may be respectively provided at both ends of the U-shaped strap 11. The telescopic joints facilitate the adjustment of the extension lengths of both ends of the U-shaped strap 11, so as to better adapt to the head shapes of different users.

[0047] As Figure 1 and Figure 4 shown, the first earphone assembly 20 includes: a first earphone main body 21 connected to one end of the strap assembly 10 and a first elastic liquid sac 22 mounted on the first earphone main body 21. As Figure 6 and Figure 7 shown, the first earphone main body 21 is provided with a first annular groove 211 for receiving the first elastic liquid sac 22 and a first avoidance groove 212 located on the periphery of the first annular groove 211. The first avoidance groove 212 communicates with the first annular groove 211. As Figure 5 shown, the first elastic liquid sac 22 includes: a first bottom plate 221 attached to the bottom of the first annular groove 211 and a first elastic sac body 222 connected to the first bottom plate 221. As Figure 4 and Figure 6 shown, the bottom of the first elastic sac body 222 is fixedly connected to the first bottom plate 221. The first bottom plate 221 provides a bottom shaping function for the first elastic sac body 222, so that the first elastic sac body 222 can be stably connected to the first annular groove 211. The periphery of the first elastic sac body 222 is closely attached to the inner side wall of the first annular groove 211, and the top of the first elastic sac body 222 extends outside the first annular groove 211.

[0048] As Figure 1 and Figure 8 shown, the second earphone assembly 30 includes: a second earphone main body 31 connected to the other end of the strap assembly 10 and a second elastic liquid sac 32 mounted on the second earphone main body 31. As Figure 10 shown, the second earphone main body 31 is provided with a second annular groove 311 for receiving the second elastic liquid sac 32 and a second avoidance groove 312 located on the periphery of the second annular groove 311. The second avoidance groove 312 communicates with the second annular groove 311. As Figure 9 shown, the second elastic liquid sac 32 includes: a second bottom plate 321 attached to the bottom of the second annular groove 311 and a second elastic sac body 322 connected to the second bottom plate 321. As Figure 8 shown, the bottom of the second elastic sac body 322 is fixedly connected to the second bottom plate 321. The second bottom plate 321 provides a bottom shaping function for the second elastic sac body 322, so that the second elastic sac body 322 can be stably connected to the second annular groove 311. The periphery of the second elastic sac body 322 is closely attached to the inner side wall of the second annular groove 311, and the bottom of the second elastic sac body 322 extends outside the second annular groove 311.

[0049] It should be noted that in this embodiment, both the first annular groove 211 and the second annular groove 311 are circular grooves. In other embodiments, they can also be waist-shaped annular grooves (i.e., with arcs at both ends and straight lines on both sides, which can refer to the design of a runway), or irregular annular grooves.

[0050] For easy disassembly and assembly, in this embodiment, the first bottom plate 221 is snap-fitted to the bottom of the first annular groove 211, and the second bottom plate 321 is snap-fitted to the bottom of the second annular groove 311. The snap-fitting method is convenient for disassembly and assembly and reduces the difficulty of assembly and subsequent maintenance. In other embodiments, magnetic attraction fixation, screw locking and other fixation methods can also be used, which can also achieve the purpose of easy disassembly and assembly.

[0051] To achieve adjustment in more dimensions, the connection method between the strap assembly 10 and the first earphone assembly 20 and the second earphone assembly 30 can be further improved.

[0052] For example, as Figure 1 shown, in this embodiment, the head-mounted Bluetooth earphone 100 further includes: a first hinge assembly 40 and a second hinge assembly 50. The first hinge assembly 40 is connected between the strap assembly 10 and the first earphone assembly 20, and the second hinge assembly 50 is connected between the strap assembly 10 and the second earphone assembly 30. After setting the hinge assemblies, the swing angles of the first earphone assembly 20 and the second earphone assembly 30 can be adjusted by rotation, so as to better adapt to the head shapes of different users.

[0053] Furthermore, as Figure 2 shown, the first hinge assembly 40 includes: a first rotating shaft 41 passing through one end of the strap assembly 10 and a first mounting ring 42 sleeved on the first rotating shaft 41. The first mounting ring 42 is sleeved on the outside of the first earphone body 21 and hinges the first earphone body 21. The second hinge assembly 50 includes: a second rotating shaft 51 passing through the other end of the strap assembly 10 and a second mounting ring 452 sleeved on the second rotating shaft 51. The second mounting ring 452 is sleeved on the outside of the second earphone body 31 and hinges the second earphone body 31. The combination of the rotating shaft and the mounting ring can achieve multi-dimensional rotation of the hinge assembly, facilitating the user to finely adjust the angle of the earphone assembly.

[0054] To prevent the hinge assemblies from accidentally loosening during use and causing the earphone assemblies to fall off, in this embodiment, as Figure 4 and Figure 8 shown, the first earphone assembly 20 may further include: a first tie belt 23 connected between the first earphone body 21 and the strap assembly 10. The second earphone assembly 30 may further include: a second tie belt 33 connected between the second earphone body 31 and the strap assembly 10. The tie belts can play a role in preventing detachment and avoid damage caused by accidental detachment of the earphone assemblies.

[0055] Brief description of the working principle:

[0056] When in use, the strap assembly 10 is placed on the human head, and the first earphone body 21 and the second earphone body 31 are respectively placed outside the human ears. At this time, the first elastic fluid sac 22 and the second elastic fluid sac 32 are closely attached to the skin on the periphery of the ears. Under the mutual extrusion of the first earphone body 21, the second earphone body 31, and the human body, the first elastic sac body 222 and the second elastic sac body 322 will deform themselves to adapt to the contour of the human head, and the first avoidance groove 212 and the second avoidance groove 312 provide space for the deformation. This design can make the first elastic sac body 222 and the second elastic sac body 322 fit the contour of the human head, and can also absorb part of the extrusion force through the deformation effect, reduce the discomfort caused by the extrusion force, and thus improve the user experience.

[0057] For the above-mentioned head-mounted Bluetooth earphone 100, an elastic fluid sac is provided at the earphone body. By utilizing the deformation characteristics of the elastic sac body, it can achieve the effects of closely attaching to the human contour and buffering, reduce the discomfort caused by the extrusion force, and improve the user experience.

[0058] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0059] The above embodiments only represent the preferred implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
