[0002] With the rapid development of mobile devices, people generally carry different electronic mobile devices with them. In order to use devices such as mobile phones and tablets in public places without affecting others due to the sound output, people usually wear headphones that are compatible with their devices. Headphones generally consist of a headphone body and ear caps. The ear caps are installed on the in-ear part of the headphone body for inserting into the ear.

[0003] Currently, the ear caps of headphones on the market are generally locked with the in-ear part, so that the ear caps are fixed on the in-ear part. The ear caps cannot be adjusted during use. Therefore, there are large differences in use for users with different ear canal depths. Its adaptability is poor. During use, different types of ear caps need to be frequently replaced to meet user needs. It cannot provide consumers with a good user experience, is very inconvenient to use, and has poor practicality. In view of this, an adjustable in-ear Bluetooth headset is proposed.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-6 The utility model provides a new technical solution: an adjustable in-ear Bluetooth headset, comprising a Bluetooth headset body 1, a heat dissipation hole 2 is opened on the outer surface of the Bluetooth headset body 1, and a fixing column 3 is fixedly installed on the left surface of the Bluetooth headset body 1;

[0028] Among them, an adjustment mechanism is provided on the Bluetooth headset body 1, which includes a hollow column 4, an earplug 5, six card holes 6, a slide groove 7, two springs 8, two fixing plates 9, a ring 10, two round holes 11, two round beads 12, a mounting hole 13 and a rubber sealing ring 14.

[0029] Furthermore, the hollow column 4 is sleeved on the outer surface of the fixed column 3, six clamping holes 6 are provided on the outer surface of the fixed column 3, and the sliding groove 7 is provided on the outer surface of the hollow column 4;

[0030] The outer surface of the hollow column 4 is provided with a mounting hole 13 .

[0031] Furthermore, two springs 8 are fixedly installed in the inner wall of the slide groove 7, and two fixing plates 9 are fixedly installed on the right ends of the two springs 8. The right surfaces of the two fixing plates 9 are inclined.

[0032] Furthermore, the circular ring 10 is fixedly sleeved on the outer surfaces of the two fixing plates 9 , and the circular ring 10 is slidably connected to the sliding groove 7 .

[0033] Furthermore, two circular holes 11 are opened in the inner wall of the chute 7 , and two round balls 12 are arranged in the inner walls of the two circular holes 11 .

[0034] Furthermore, the earplug 5 is arranged on the outer surface of the hollow column 4, and a rubber sealing ring 14 is fixedly mounted on the inner surface of the earplug 5;

[0035] When the adjustable in-ear Bluetooth headset is in use, a leftward thrust is applied to the circular ring 10 to make it move to the left. At the same time, the circular ring 10 drives the two fixing plates 9 fixedly installed on the inner surface to move to the left. At this time, the two fixing plates 9 apply pressure to the two springs 8 fixedly installed on the left surface to cause them to shrink. At this time, the two fixing plates 9 no longer block the two circular holes 11, that is, they no longer limit the two round beads 12 set in the two circular holes 11. At this time, by pulling the hollow column 4 to slide leftward on the outer surface of the fixing column 3, and aligning the two circular holes 11 opened on the hollow column 4 with the other two card holes 6 opened on the outer surface of the fixing column 3, the circular ring 10 is no longer blocked. When a leftward thrust is applied, the two springs 8 are no longer under stress. At this time, the two springs 8 expand, and the two springs 8 apply a rightward thrust to the two fixing plates 9 fixed at the right end, causing them to slide in the inner wall of the slide groove 7. At this time, the inclined surfaces of the two fixing plates 9 hit the two round balls 12 and apply a thrust to the two round balls 12 from the opposite surfaces, so that the two round balls 12 move toward the opposite surfaces and are engaged in the two card holes 6 opened on the outer surface of the fixing column 3 for fixation, thereby completing the adjustment of the earplug 5. The rubber sealing ring 14 fixed on the inner surface of the earplug 5 can be detached from the mounting hole 13 opened on the outer surface of the hollow column 4 by toggling the earplug 5, so as to replace a different earplug 5.

[0036] The adjustable in-ear Bluetooth headset applies a leftward thrust to the circular ring 10, causing it to drive the two fixing plates 9 fixed on the inner surface to move to the left. At this time, the two round balls 12 are no longer subjected to the pressure of the fixing plate 9, and the two round balls 12 are disengaged from the card holes 6 opened on the outer surface of the fixing column 3. At this time, the hollow column 4 can be pulled to move leftward on the outer surface of the fixing column 3, so that the earplug 5 on the hollow column 4 can be adjusted to the depth of the ear. It can be adapted to users with different depths of ear canals, so as to obtain a better listening experience and be more convenient. In addition, the adjustable in-ear Bluetooth headset can be used to replace different earplugs 5 by dialing the earplug 5 to disengage the earplug 5 from the mounting hole 13 opened on the outer surface of the hollow column 4. The replaced earplug 5 can be used for cleaning, keeping the earplug 5 clean, and preventing the ear canal from being infected by bacteria, further protecting the user and being more convenient.

[0037] Working principle: When the adjustable in-ear Bluetooth headset is used, a leftward thrust is applied to the circular ring 10 to make it move to the left. At the same time, the circular ring 10 drives the two fixed plates 9 fixed on the inner surface to move to the left. At this time, the two fixed plates 9 apply pressure to the two springs 8 fixed on the left surface to cause them to shrink. At this time, the two fixed plates 9 no longer block the two circular holes 11, that is, they no longer limit the two round beads 12 set in the two circular holes 11. At this time, by pulling the hollow column 4 to slide to the left on the outer surface of the fixed column 3, and aligning the two circular holes 11 opened on the hollow column 4 with the other two card holes 6 opened on the outer surface of the fixed column 3, the circular holes 11 are no longer blocked. The ring 10 applies a leftward thrust, and at the same time, the two springs 8 are no longer under stress. At this time, the two springs 8 expand, and the two springs 8 apply a rightward thrust to the two fixed plates 9 fixed at the right end, causing them to slide in the inner wall of the slide groove 7. At this time, the inclined surfaces of the two fixed plates 9 hit the two round balls 12 and apply relative thrust to the two round balls 12, causing the two round balls 12 to move toward the opposite surfaces and be engaged into the two card holes 6 opened on the outer surface of the fixing column 3 for fixation, completing the adjustment of the earplug 5. The earplug 5 can be toggled to disengage the rubber sealing ring 14 fixed on the inner surface of the earplug 5 from the mounting hole 13 opened on the outer surface of the hollow column 4 to replace a different earplug 5.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
