Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a foldable headphone. Background Art

[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. Headphones are typically detachable from the media player, connecting via a plug, allowing you to listen to music without disturbing others. They also block out ambient sound, making them particularly useful in noisy environments.

[0003] In order to facilitate storage and carrying, existing foldable headphones generally rotate and fold the earphone part. Due to the lack of an integrated structure to limit the rotation of the earphone, the rotated earphone is prone to rotating during carrying, thereby reducing the folding and storage effect of the headset. For this purpose, the present invention provides a foldable headset. Utility Model Content

[0004] In order to solve the problem in the above background technology that it is difficult to limit and fix the rotated earphones, which makes the earphones easily rotate during carrying, the utility model provides a foldable headphone.

[0005] The utility model adopts the following technical solution to realize: a foldable headphone, comprising:

[0006] A headband, wherein both ends of the headband are hinged to have movable ends via hinges, and the distal ends of the movable ends are rotatably connected to the earphone body;

[0007] The limiting and fixing component includes a connecting shaft fixedly connected to the end of the movable end, a connecting seat fixedly connected to the earphone body and rotatably connected to the connecting seat and the connecting shaft, a movable end is provided with a movable groove, a movable block is slidably connected to the inside of the movable groove, a shift block is fixedly connected to the movable block and the shift block extends to the outside of the movable groove, an insertion rod is fixedly connected to the bottom of the movable block, two groups of jacks are provided on the top of the connecting seat, and a spring is also provided inside the movable groove.

[0008] As a further improvement of the above solution, a limiting block is fixedly connected to the connecting shaft, a limiting groove is provided on the top of the connecting seat, and the limiting groove and the limiting block are slidably connected.

[0009] As a further improvement of the above solution, the arc of the limiting groove is ninety degrees.

[0010] As a further improvement of the above solution, the diameter of the insertion rod matches the diameter of the insertion hole.

[0011] As a further improvement of the above solution, both ends of the spring are fixedly connected to the inner wall of the moving groove and the moving block respectively.

[0012] As a further improvement of the above solution, the angle between the two groups of jacks is ninety degrees.

[0013] As a further improvement of the above solution, a rubber pad is fixedly connected to the inner side of the headband.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model drives the insertion rod upward by pulling the shift block upward. At this time, the moving block compresses the spring and causes the insertion rod to leave the socket. After rotating the earphone body by 90 degrees, the shift block is released. At this time, under the rebound action of the spring, the insertion rod will be inserted into another socket, thereby achieving the purpose of limiting and fixing the rotating earphone body, effectively avoiding the problem of the earphone easily rotating during carrying due to the difficulty in limiting and fixing the rotated earphone, improving the folding and storage effect of the earphone, and having strong practicality.

[0016] 2. The present invention can limit and fix the earphone by inserting the rod into the jack, thereby preventing the earphone from rotating when in use, ensuring the wearing effect of the earphone and further improving the practicality of the earphone. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example 1:

[0026] Please combine Figure 1-5 , a foldable headphone of this embodiment includes:

[0027] A headband 1, with movable ends 2 hinged at both ends via hinges, and the distal ends of the movable ends 2 rotatably connected to the earphone body 3;

[0028] The limiting and fixing assembly includes a connecting shaft 101 fixedly connected to the end of the movable end 2, a connecting seat 102 fixedly connected to the earphone body 3 and rotatably connected to the connecting seat 102 and the connecting shaft 101, a movable groove is provided on the movable end 2, a movable block 103 is slidably connected to the inside of the movable groove, a shift block 104 is fixedly connected to the movable block 103 and the shift block 104 extends to the outside of the movable groove, a rod 105 is fixedly connected to the bottom of the movable block 103, two sets of jacks 106 are provided on the top of the connecting seat 102, and a spring 107 is also provided inside the movable groove. The two ends of the spring 107 are fixedly connected to the inner wall of the movable groove and the movable block 103 respectively. The limiting block 1001 is fixedly connected to the connecting shaft 101. The top of the connecting seat 102 is provided with a limiting groove 1002 and the limiting groove 1002 is slidably connected to the limiting block 1001. The arc of the limiting groove 1002 is ninety degrees, which can control the maximum rotation angle of the earphone body 3 to ninety degrees. The diameter of the insertion rod 105 matches the diameter of the jack 106 to ensure that the insertion rod 105 can be smoothly inserted into the jack 106. The angle between the two groups of jacks 106 is ninety degrees.

[0029] The implementation principle of a foldable headphone in the embodiment of the present application is as follows: when the headphone needs to be folded, the headphone is first picked up vertically and the shift block 104 is pulled upward to drive the insertion rod 105 upward. At this time, the moving block 103 compresses the spring 107 and causes the insertion rod 105 to leave the socket 106. After the headphone body 3 is rotated 90 degrees and the shift block 104 is released, the insertion rod 105 is inserted into another socket 106 under the rebound action of the spring 107, thereby achieving the purpose of limiting and fixing the rotating headphone body 3, effectively avoiding the problem of the headphone easily rotating during carrying due to the difficulty in limiting and fixing the rotated headphone. Then, the hinge between the movable end 2 and the headband 1 is used to rotate the two sets of headphone bodies 3 inward to the maximum angle respectively. Finally, the two sets of headphone bodies 3 are released at the same time. Under the action of gravity, the two sets of headphone bodies 3 will rotate outward at the same time. Then, the two sets of headphone bodies 3 will contact and lean against each other, preventing them from rotating further outward, thereby achieving the purpose of folding and storing the headphone.

[0030] When the earphones need to be used, first rotate the two sets of earphone bodies 3 inward to the maximum angle at the same time, then rotate the earphone bodies 3 outward in turn, then pull the dial block 104 upward again, and finally rotate the earphone bodies 3 ninety degrees and release the dial block 104, and insert the insertion rod 105 into the jack 106, so that the earphones can be limited and fixed, thereby preventing the earphones from rotating during use and ensuring the wearing effect of the earphones.

[0031] Example 2:

[0032] This embodiment is a further improvement on the basis of the embodiment 1 in that a rubber cushion 4 is fixedly connected to the inner side of the headband 1 , which can increase the comfort of wearing the headset.

[0033] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
