Description

Technical Field

[0001] The invention relates to the technical field of electronic equipment, in particular to an ear-hook type earphone assembly. Background Art

[0002] Earhook earphones are earphones with auxiliary hanging decorations added to the side of the earphones for easy use. The earhook ensures the reliability of the user's wearing, especially when exercising or in a bumpy environment. The earhook design allows the plug of the large-caliber unit to fit firmly on the user's ear hole.

[0003] Existing ear-hook headphones generally connect the earphones and the ear hooks flexibly, and the wearing angle is flexibly adjusted through the connection to meet the needs of different consumers. However, since there is no fixed structure, the earphones are easily deviated from the pre-adjusted position during use after adjustment, affecting the user experience. In addition, in order to match the auricle, the volume of the ear hook is much larger than the earphone body, which increases the storage space of the ear-hook headphones and easily causes the ear hook to deform and the earphone to bump when stored.

[0019] Beneficial Effects

[0020] The present invention provides an ear-hook type earphone assembly, which has the following beneficial effects:

[0021] The device is provided with an ear hook (2), and the earphone body (31) is held and rotated with the rotating shaft sleeve (323) as the axis, and the installation box (331) is pushed to slide in the longitudinal adjustment groove (215), so as to quickly adjust the angle and position of the earphone body (31) to match the auricle of the user. When the rotating shaft sleeve (323) rotates, the connecting end (222) fixed on the fixing groove (325) is wound around the outer wall of the installation shaft (324), and extends or shortens with the rotation angle, so that the rotating shaft sleeve (323) can keep the position unchanged after the rotation, and at the same time, the installation box (331) is moved in the longitudinal adjustment groove ( When the connecting end (222) slides in the longitudinal adjustment groove (215), the connecting end (222) is extended or shortened accordingly, and the position of the installation box (331) in the longitudinal adjustment groove (215) remains unchanged after adjustment. At the same time, the connecting end (222) is limited by the limiting groove (333), the limiting shaft (332) guides and the through hole (322) is limited and then wound around the outer wall of the installation shaft (324), so that the fixed force spring coil (221) timely adjusts the rotation of the rotating shaft sleeve (323) and the movement of the installation box (331), and ensures the smooth extension and retraction of the connecting end (222), thereby improving the stability of the entire adjustment process;

[0022] At the same time, by providing a driving rod (23), the protruding end of the driving belt (232) is fixedly connected to the outer wall of the connecting plate (321). When the connecting plate (321) is away from the rod body (233) or rotates counterclockwise, the driving belt (232) is pulled by the connecting plate (321), the rod body (233) rotates relative to the driving block (231), and the torsion spring is deformed, so that the ear hanging box (21) rotates counterclockwise relative to the main box (11), and the angle between the main box (11) and the ear hanging box (21) increases, which is more suitable for consumers with large auricles. When the connecting plate (321) is close to the rod body (233) or rotates clockwise, the angle between the main box (11) and the ear hanging box (21) decreases, which is more suitable for consumers with small auricles.

[0023] Furthermore, when the installation box (331) moves to fit with the fixed force spring roll (221), the deformed torsion spring drives the rod body (233) to rotate and reel the driving belt (232) onto the outer wall of the rod body (233), and at the same time drives the ear hook box (21) to rotate, so that the earphone body (31) and the outer ends of the ear hook box (21) are respectively stored in the first storage groove (13) and the second storage groove (14), thereby reducing the volume of the ear hook earphone and preventing the earphone and the ear hook from being bumped and deformed when stored.

[0048] Specifically, the adjustment component (22) comprises a constant force spring coil (221) and a connecting end (222), and the connecting end (222) penetrates through the outer wall of the constant force spring coil (221) and protrudes.

[0049] It should be noted that when the connecting end (222) is subjected to a pulling force or a pushing force, it will stretch or retract, and the length will remain unchanged after the external force is removed.

[0050] Specifically, the driving rod (23) comprises a rod body (233), the lower end of the rod body (233) passes through the lower box body (212) and is equipped with a driving block (231), the upper end of the rod body (233) passes through the upper box body (211) and is equipped with a driving block (231), the outer wall of the rod body (233) is fixedly connected to both the upper box body (211) and the lower box body (212), and the outer wall of the rod body (233) located in the inner cavity of the lower box body (212) is wound with a driving belt (232).

[0051] It should be noted that the driving block (231) comprises a mounting box and a torsion spring, one end of the torsion spring is fixedly connected to the outer wall of the rod body (233), and the other end is fixedly connected to the inside of the mounting box, the upper and lower ends of the rod body (233) are both rotatably connected to the mounting box, and the two sets of mounting box outer walls are respectively fixedly connected to the top or bottom of the connecting groove (12), the main body box (11) is held, and the driving belt (232) is pulled, the driving belt (232) drives the rod body (233) to rotate to deform the torsion spring, and at the same time the rod body (233) drives the upper box body (211) and the lower box body (212) to rotate counterclockwise synchronously, and after the driving belt (232) is loosened, the deformed torsion spring winds the driving belt (232) around the rod body (233), and at the same time drives the upper box body (211) and the lower box body (212) to rotate clockwise.

[0052] See also Figures 8 to 10 The earphone (3) comprises an earphone body (31), an outer wall of the earphone body (31) is fixedly connected to a driving plate (32), an end of the driving plate (32) away from the earphone body (31) is rotatably connected to a driving sleeve (33), and when the earphone body (31) is adjusted, the earphone body (31) rotates around the driving sleeve (33) with the driving plate (32) as a rotation radius, thereby achieving angle adjustment of the earphone body (31).

[0053] Specifically, the driving sleeve (33) includes an installation box (331), the outer wall of the installation box (331) is provided with a circumferential adjustment groove (335), the outer wall of the installation box (331) is provided with a limit groove (333) in an area away from the circumferential adjustment groove (335), and the interior of the installation box (331) is provided with a placement groove (334), and the bottom of the placement groove (334) is rotatably connected to the limit shaft (332).

[0054] The driving plate (32) includes a connecting plate (321), which passes through the limiting through groove (213) and the circumferential adjustment groove (335) in sequence and extends into the placement groove (334) and is fixedly connected with a rotating shaft sleeve (323). The rotating shaft sleeve (323) rotates in the placement groove (334) and has a mounting shaft (324) coaxially arranged inside. A through hole (322) is opened on the outer wall of the rotating shaft sleeve (323) near the adjustment component (22). The shaft (332) is arranged in an area adjacent to the through hole (322) and the limiting groove (333) and is used to guide the connecting end (222). A fixing groove (325) is provided on the side of the installation shaft (324) away from the through hole (322). The connecting end (222) passes through the limiting groove (333), is guided by the limiting shaft (332), and then penetrates into the limiting shaft (332), is wound clockwise around the outer wall of the installation shaft (324), and is finally fixedly connected inside the fixing groove (325).

[0055] It should be supplemented that the rotating shaft sleeve (323) rotates in the placement groove (334), and the circumferential adjustment groove (335) limits the rotation angle of the connecting plate (321). The rotation angle range of the connecting plate (321) in the circumferential adjustment groove (335) is 5-30 degrees.

[0056] It should also be added that the shape and position of the earphone body (31) are adapted to the first storage groove (13), and the second storage groove (14) is adapted to the shape of the end of the ear hook box (21) facing away from the main box (11). When the earphone body (31) moves to the middle of the ear hook box (21) and the ear hook box (21) is folded toward the main box (11) for storage, part of the earphone body (31) is located in the first storage groove (13) and fits with the inner wall of the first storage groove (13), and part of the end of the ear hook box (21) facing away from the main box (11) is stored in the second storage groove (14), thereby improving the stability of the storage state and protecting the earphone body (31) at the same time.

[0057] At the same time, the thickness of the connecting plate (321) is equal to the height of the limiting through groove (213), the thickness of the rotating shaft sleeve (323) is equal to the height of the mounting groove (334), and the thickness of the rotating shaft sleeve (323) is greater than the thickness of the connecting plate (321), so as to prevent the rotating shaft sleeve (323) from falling out of the mounting groove (334) when rotating, and at the same time improve the stability of the movement of the installation box (331).

[0058] It can be understood that when the earphone body (31) drives the connecting plate (321) to rotate clockwise, the connecting end (222) is disengaged from the outer wall of the mounting shaft (324), passes through the through hole (322), is guided by the limiting shaft (332), and then passes through the limiting groove (333) to be rolled into the interior of the fixed force spring roll (221). When the earphone body (31) drives the mounting box (331) to slide in the direction close to the device body (1), the connecting end (222) is also rolled into the fixed force spring roll (221). When the earphone body (31) drives the connecting plate (321) to rotate counterclockwise or drives the mounting box (331) to slide away from the device body (1), the connecting end (222) is wound around the outer wall of the mounting shaft (324), and then the connecting end (222) is stretched by the guide of the limiting shaft (332). The characteristics of the constant force spring roll (221) enable the stretched or rolled connecting end (222) to maintain the same position after adjustment, thereby improving the stability and reliability after adjustment.

[0059] See also Figure 4 and Fig.10 One end of the driving belt (232) facing away from the rod body (233) is fixedly connected to the side wall of the connecting plate (321). When the connecting plate (321) rotates along the circumferential adjustment groove (335) or moves along the limit groove (213), the driving belt (232) can be in a stretched or relaxed state. When stretched, the torsion spring is deformed, and when relaxed, the deformed torsion spring is reset.

[0060] It should be added that the torsional force of the torsion spring is smaller than the elastic modulus of the constant force spring coil (221), and the state of the torsion spring is only affected by the position of the earphone body (31). At the same time, the state of the torsion spring will not affect the extension and winding of the connecting end (222).

[0061] Principle: The present invention provides an ear-hook type earphone assembly. When in use, the earphone body (31) is held and adjusted according to the auricle. When it needs to be adjusted larger, the earphone body (31) is held and the connecting plate (321) drives the rotating shaft sleeve (323) to rotate counterclockwise in the installation groove (334). At the same time, the installation box (331) is moved along the longitudinal adjustment groove (215) to the side away from the device body (1), and the connecting end (222) wound on the outer wall of the installation shaft (324) is partially unwound, and the earphone body (31) is adjusted to the outer wall of the installation shaft (324). The rod (233) is guided by the limit shaft (332) through the through hole (322) and then rolled into the fixed force spring roll (221) through the limit groove (333). The fixed force spring roll (221) keeps the position of the earphone body (31) unchanged after rotation and movement adjustment. At the same time, the connecting plate (321) pulls the driving belt (232) to rotate the rod body (233) relative to the driving block (231), and at the same time drives the ear hanging box (21) to rotate counterclockwise relative to the main body box (11), and the angle between the two increases. When the earphone body (31) needs to be adjusted, the connecting plate (321) is rotated clockwise by holding the earphone body (31) and the mounting box (331) is moved toward the device body (1). The connecting end (222) is extended and the position of the earphone body (31) after adjustment remains unchanged. At the same time, the pulling force of the connecting plate (321) on the driving belt (232) disappears. The deformed torsion spring drives the rod body (233) to rotate and retracts the driving belt (232) on the outer wall of the rod body (233). At the same time, the ear hanging box (21) is driven to rotate clockwise relative to the main body box (11). The angle between the two is The ear hook (331) is reduced, thereby improving the adaptability of the ear hook and the auricle; after use, the installation box (331) is moved to fit with the fixed force spring roll (221), at which time the earphone body (31) is located in the middle of the inner side wall of the ear hook box (21), the driving belt (232) is completely not affected by the connecting plate (321), and the torsion spring returns to its original position. At this time, the ear hook box (21) is folded toward the main box (11), and the earphone body (31) is stored in the first storage groove (13), thereby reducing the volume of the ear hook earphone and preventing the earphone from being deformed or damaged by external force when stored.
