Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a sliding adjustment structure for headphones and headphones. Background Technology

[0002] Over-ear headphones offer advantages such as excellent soundstage and comfortable wear. Since they don't go into the ear, they avoid chafing the ear canal and better protect the eardrum. Over-ear headphones mainly consist of earcups, a headband, and internal acoustic modules. The headband is the primary load-bearing component, distributing the weight of the headphones upwards. It has an internal metal frame for strength and flexibility, and is covered with a flexible material for comfortable wear. Typically, the headband has an adjustable mechanism inside to accommodate various head sizes.

[0003] In existing technologies, adjustment typically employs ratchet or snap-fit ​​mechanisms. These mechanisms typically use a slide rail with a series of evenly distributed grooves, and a spring-loaded pin or plastic latch inside the slider. When the earcup is pulled, the pin springs from one groove to another, producing a click and providing clear feedback on the adjustment level. However, such structures can only be adjusted within preset levels and cannot achieve perfect fine-tuning. Furthermore, after prolonged use, the plastic latch or slide rail grooves may wear down, leading to loosening and slippage. Moreover, existing adjustment mechanisms involve numerous internal components, resulting in high costs and low assembly efficiency.

[0004] Therefore, it is necessary to provide a headphone sliding adjustment structure that is more stable, easier to adjust, and reduces the number of parts to improve assembly efficiency. Utility Model Content

The top cover 20 is installed on the base 10 and engaged with the locking blocks 12. The top cover 20 has an inwardly recessed cavity 22 to form a receiving cavity 101 between itself and the base 10 when installed. The receiving cavity 101 can accommodate multiple components of the headband. On the other hand, the sliding arm 30 is located inside the receiving cavity 101 with one end protruding outside the receiving cavity 101. The sliding arm 30 is movably mounted on the base 10, with both sides located within the gap 110 formed by the base 10 and the locking block 12. By operating the end of the sliding arm 30 protruding from the receiving cavity 101, the sliding arm 30 can slide a preset distance along the base 10. The gap 110 can position the sliding arm 30 from both sides, making the installation of the sliding arm 30 more stable and allowing the sliding arm 30 to slide. The overall structure is compact and reasonable, and the operation is convenient.

[0042] Compared with the prior art, the sliding adjustment structure 100 of the present invention for headphones includes a base 10 and a top cover 20, and a sliding arm 30 located between the base 10 and the top cover 20. The base 10 includes a base plate 11 and locking blocks 12 protruding from both sides of the base plate 11. The base plate 11 can be used to install various components, and the locking blocks 12 can be engaged and fixed with the top cover 20. There is a gap 110 between the locking blocks 12 and the base plate 11. The gap 110 between the locking blocks 12 and the base plate 11 can position the sliding arm 30 and allow the sliding arm 30 to slide. The structure is compact and reasonable. The top cover 20 is installed on the base 10 and engaged with the locking blocks 12. The top cover 20 has an inwardly recessed cavity 22 to form a receiving cavity 101 with the base 10. The receiving cavity 101 can accommodate various structures. The sliding arm 30 is located within the receiving cavity 101, with one end protruding outside the receiving cavity 101. The sliding arm 30 is movably mounted on the base 10, with both sides located within the gap 110 formed by the base 10 and the locking block 12. The gap 110 can position the sliding arm 30 from both sides, making the installation of the sliding arm 30 more stable. When it is necessary to adjust the headband of the headphones, operate the end of the sliding arm 30 protruding from the receiving cavity 101 to slide the sliding arm 30 along the base 10 a preset distance. Thus, the length of the headband can be adjusted according to actual needs. The sliding adjustment structure 100 for headphones of this utility model has a more stable structure, is not easily worn, is easy to adjust, has fewer parts, and has higher assembly efficiency.

[0043] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 9 In some optional embodiments, the base 10 has two protruding first teeth 15 on both sides of the surface on which the sliding arm 30 is mounted, extending towards the center of the receiving cavity 101, to engage with the sliding arm 30. The locking block 12 can be disassembled in the middle to accommodate the first teeth 15, so that the sliding arm 30 slides along the gap 110 and makes sliding contact with the first teeth 15. Alternatively, the first teeth 15 may be located within the gap 110 and make sliding contact with the sliding arm 30. Figure 5 As shown, the first tooth 15 has a hollowed-out portion 151, allowing it to move elastically within a certain range to pull the sliding arm 30. The number of first teeth 15 is at least one. On the other hand, multiple second teeth 32, which engage with the first teeth 15, are evenly distributed at predetermined intervals on both sides of the sliding arm 30. The first teeth 15 and the second teeth 32 have an arc-shaped structure. The arc-shaped structure of the first teeth 15 and the second teeth 32 allows for better transition and sliding, and wear will not affect normal use. The first teeth 15 engage with different second teeth 32 to position the sliding arm 30 at different positions on the base 10.

[0044] Please see Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 10 In some optional embodiments, the headphone sliding adjustment structure 100 further includes a damping element 50. A recessed mounting groove 16 is formed in the base plate 11, and the damping element 50 is installed within the mounting groove 16, with one side of the damping element 50 attached and fixed to the base plate 11. A sliding arm 30 is disposed on the base plate 11 and in frictional contact with the damping element 50. Both sides of the sliding arm 30 are located within gaps 110 on both sides, which are used to position the sliding arm 30 and allow it to slide. Additionally, one end of the damping element 50 has a protruding abutment 51 extending from the mounting groove 16, which elastically abuts against the sliding arm 30 to ensure frictional sliding between the damping element 50 and the sliding arm 30. Furthermore, one end of the mounting groove 16 has a guide block 17, which serves both to limit the position of the damping element 50 and to guide the sliding arm 30 when it is pulled. Furthermore, support blocks 18 are protruding from both sides of the mounting groove 16. These support blocks 18 support the sliding arm 30 to prevent it from excessively pressing against the damping element 50 and becoming unable to slide. The support blocks 18 also allow the sliding arm 30 to slide rubbed against the damping element 50, resulting in a reasonable structural design. In this embodiment, the damping element 50 is made of either a damping rubber pad or foam. The damping rubber pad and foam allow the sliding arm 30 to experience uniform friction during the pulling and retracting process, enabling adjustment to any suitable distance while maintaining quiet operation.
