Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a foldable portable headphone. Background Technology

[0002] Headphones are a common type of audio equipment. Over-ear headphones, with their large earcups that completely cover the ears, provide excellent sound quality and noise isolation, making them popular with many people. However, due to their large size and inconvenience in storage, foldable headphones have emerged as a solution.

[0003] However, current folding headphones cannot be secured after folding. When preventing them from being carried in a bag, they may rotate freely, affecting the items in the bag, and in severe cases, even damaging the headphones.

[0004] Therefore, given that current folding headphones cannot be secured after folding, which may cause them to rotate freely when carried in a bag, affecting other items and potentially damaging the headphones, a foldable portable headphone design could be developed. This design would lock the folding hinge to prevent the headphones from rotating freely after folding, reducing their impact on other items and protecting them from damage. Utility Model Content

[0005] To overcome the current problem that folding headphones cannot be secured after folding, which may cause them to rotate freely when carried in a bag, affecting items inside the bag, and even potentially damaging the headphones if the rotation is too large.

[0006] The technical solution of this utility model is as follows: a foldable portable earphone, including an earphone body, a protective component, earcups, and an adjustment component. The earphone body is provided in two sets. The earcups are fixedly installed on one side of the earphone body, and the protective component is provided on the other side of the earphone body.

The locking frame is slidably connected to the rotating shaft through the mounting hole. The locking frame and the rotating shaft cannot rotate. The adjustment component is provided on the top of the mounting block.

[0007] Preferably, the earcups are designed to directly contact the skin around the user's ears during wear, ensuring softness and a snug fit, thus improving wearing comfort. Protective components protect the headphone body. A hinge allows the mounting block and connecting frame to rotate and connect, enabling the headphone body to fold along the hinge for easy carrying. A mounting hole is provided for installing the locking frame. The locking frame, in conjunction with the locking ring, locks the hinge, preventing the headphone body from rotating freely along the hinge.

[0008] Preferably, the protective components include a shield and noise-canceling patterns. The shield is located on one side of the headphone body, and multiple sets of noise-canceling patterns are provided on one side of the shield.

[0009] Preferably, two sets of fixing plates are fixedly installed on the outer periphery of the headphone body. The fixing plates are fixedly connected to the cover by bolts, and each fixing plate is provided with two sets of bolts.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment: a foldable portable earphone, including an earphone body 1, a protective component, earcups 4, and an adjustment component. The earphone body 1 has two sets of earcups 4 fixedly installed on one side of the earphone body 1, and the protective component is located on the other side of the earphone body 1. A connecting frame 101 is fixedly installed on the top of the earphone body 1. A rotating shaft 102 passes through the connecting frame 101 and is rotatably connected to the connecting frame 101. A mounting block 103 is fixedly installed around the rotating shaft 102. A locking ring 104 is fixedly installed on one side of the connecting frame 101, located around the rotating shaft 102. One end of the rotating shaft 102 has a mounting hole 105, and the locking frame 106 slides against the rotating shaft 102 through the mounting hole 105. The locking bracket 106 and the rotating shaft 102 are not rotatable. The adjustment component is located above the mounting block 103. The earcups 4 are designed to directly contact the skin around the user's ears when worn, ensuring softness and a snug fit, thus improving wearing comfort. The protective component protects the headphone body 1. The rotating shaft 102 allows the mounting block 103 and the connecting bracket 101 to be rotatably connected, so that the headphone body 1 can be folded along the rotating shaft 102 for easy carrying. The locking bracket 106 is installed through the mounting hole 105. The locking bracket 106 and the locking ring 104 work together to lock the rotating shaft 102, preventing the headphone body 1 from rotating freely with the rotating shaft 102.

[0025] Please see Figures 1-3 In this embodiment, the protective component includes a protective cover 201 and noise-reducing patterns 202. The protective cover 201 is disposed on one side of the earphone body 1, and multiple sets of noise-reducing patterns 202 are provided on one side of the protective cover 201. By providing the protective cover 201, the earphone body 1 can be protected. By providing the noise-reducing patterns 202, more external noise can be absorbed and reflected, improving the noise reduction effect of the earphone. Two sets of fixing plates 301 are fixedly installed on the periphery of the earphone body 1. The fixing plates 301 and the protective cover 201 are fixedly connected by bolts 302. Each set of fixing plates 301... Two sets of bolts 302 are provided on 01; the fixing plate 301 and the protective cover 201 can be fixedly connected by the bolts 302, thereby fixing the protective cover 201 to one side of the earphone body 1 by the fixing plate 301; a dustproof cotton pad 501 is fixedly provided inside the earphone body 1, and a letter mark 502 is fixedly installed on the surface of the dustproof cotton pad 501; the dustproof cotton pad 501 can protect the earphone body 1 and reduce the entry of dust, and the letter mark 502 can make it easy for users to distinguish between the left and right ears for wearing.

[0026] Please see Figures 4-5In this embodiment, the earcups 4 are composed of a leather outer layer 401 and memory foam filling 402, with the memory foam filling 402 disposed inside the leather outer layer 401. By allowing the leather outer layer 401 to directly contact the user's skin, and by providing the memory foam filling 402, the softness of the earcups 4 can be ensured, improving wearing comfort. The adjustment assembly includes an outer sleeve 601 and an inner insertion block 602. The inner insertion block 602 is fixedly installed above the mounting block 103, and the outer sleeve 601 is disposed around the inner insertion block 602. The outer sleeve 601 and the inner insertion block 602 are slidably connected, and there is a certain amount of damping between them. By allowing the inner insertion block 602 to slide within the outer sleeve 601... The headphone body 1 can be adjusted to fit the user's head circumference during wear. An elastic connecting piece 7 is fixedly installed between the two outer sleeves 601. The elastic connecting piece 7 securely connects the two outer sleeves 601 and, due to its elasticity, allows for position adjustment of the headphone body 1 according to the user's head circumference. A flexible pad 801 is fixedly installed below the elastic connecting piece 7 and is fixedly connected to the outer sleeve 601. Multiple ventilation holes 802 are formed on the surface of the flexible pad 801. By ensuring direct contact between the flexible pad 801 and the user's head, softness and comfort are guaranteed, while the ventilation holes 802 improve breathability.

[0027] When working, the elasticity of the elastic sheet itself allows the headphone body 1 to be easily worn. The inner insert 602 slides inside the outer sleeve 601, and the position of the headphone body 1 can be adjusted according to the user's head circumference.

[0028] The earcups 4 are in direct contact with the user's skin to ensure softness and fit, improving wearing comfort. The dustproof cotton pad 501 inside the headphone body 1 can reduce the entry of dust. The letter markings 502 make it easy for users to quickly identify the left and right ears.

[0029] The cover 201 can be fixed to one side of the headphone body 1 by using the bolt 302 and the fixing plate 301, thereby providing protection for the headphone body 1. The noise reduction texture 202 can reflect and absorb more external noise, thus improving the noise reduction effect.

[0030] When not in use, the locking bracket 106 can be pulled out of the pivot 102, allowing the connecting bracket 101 to rotate along the pivot 102, thereby folding the headphone body 1 inward to reduce its size for storage. After folding, the locking bracket 106 can be inserted back into the pivot 102 through the mounting hole 105, thereby locking the pivot 102 by engaging the locking bracket 106 with the locking ring 104 to prevent the headphone body 1 from rotating arbitrarily.

[0031] Through the above steps, the connecting bracket 101 and the mounting block 103 are rotatably connected by the mounting shaft. When not in use, the connecting bracket 101 can be rotated by the pivot 102, thereby folding the earphone body 1 inward to reduce its size and facilitate storage. The locking bracket 106 can be installed using the mounting hole 105. By setting the locking bracket 106 and the locking ring 104 to engage with each other, the pivot 102 is locked, which can prevent the earphone body 1 from rotating at will and causing damage to the earphone body 1. This solves the problem that current folding earphones cannot be fixed after folding, which may cause the earphones to rotate at will when carried in a bag, affecting the items in the bag, and may even damage the earphones if the rotation is too large.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
