[0002] In-ear headphones with a rotating adjustment mechanism are high-performance audio devices with adaptive adjustment capabilities. Their core feature is that the headphones can be flexibly adjusted at multiple angles through a mechanical rotating structure. These headphones are widely used in scenarios such as music appreciation, sports and fitness, and commuting, and are especially suitable for users who have high requirements for sound quality and wearing comfort.

[0003] Existing headphone and cable connection structures are fixed and simple, lacking flexible adjustment functions and making it difficult to adapt to different users' ear canal angles; the clamping structure of the connection component is simple, lacking buffering and self-adjustment capabilities, resulting in insufficient wearing comfort and easy loosening and falling off; the rotation adjustment mechanism of the rotating component lacks precision, lacks stable limit and elastic reset functions, affecting the stability of sound quality transmission; therefore, an in-ear headphone with a rotation adjustment mechanism is proposed.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example

[0024] Reference Figure 1-4 This is an embodiment of the present invention, which provides an in-ear headphone with a rotating adjustment mechanism, comprising:

[0025] The device includes a plug 101, a limiting sleeve 102 fixedly connected to the side of the plug 101, a connecting wire 103 inserted into the center of the limiting sleeve 102, and an earphone body 104 fixedly connected to the end of the connecting wire 103.

[0026] The headphone body 104 includes a fixed shell 104a, a connecting component 104b fixedly connected to the end of the fixed shell 104a, and a rotating component 104c used in conjunction with the connecting component 104b.

[0027] The headphone body 104 also includes a speaker 104d fixedly connected to the center of the rotating assembly 104c, a headphone cover 104e sleeved on the outer surface of the speaker 104d, and a sound outlet 104f opened on the side surface of the headphone cover 104e.

[0028] Specifically, when the user wears the earphone body 104, it is placed into the ear canal. The telescopic tube 104b-3 of the connecting component 104b pushes the clamping block 104b-6 to adapt to fit the auricle through the compression spring 104b-5. The connecting spring 104c-4 of the rotating component 104c causes the connecting block 104c-5 to drive the card plate 104c-6 to rotate flexibly in the slot 104b-2. With the buffering effect of the elastic rod 104c-7, multi-angle adjustment is achieved. The speaker 104d is automatically adjusted to the optimal angle through the rotatable rotating component 104c to ensure that the sound outlet 104f is always facing the ear canal. The cooperation of the limiting ring 104c-2 and the limiting frame 104c-3 maintains rotational stability, so that the earphone can still maintain a comfortable fit when the user's head moves, while ensuring that the sound transmission quality is not affected, and achieving continuous sound quality optimization during dynamic wearing.

[0029] The connecting assembly 104b includes a housing 104b-1, slots 104b-2 formed on both sides of the housing 104b-1, and a telescopic cylinder 104b-3 used in conjunction with the slots 104b-2.

[0030] The connecting assembly 104b also includes a compression rod 104b-4 inserted into the center of the telescopic cylinder 104b-3, a compression spring 104b-5 sleeved on the outer surface of the compression rod 104b-4, and a clamping block 104b-6 fixedly connected to the end of the compression spring 104b-5.

[0031] The rotating assembly 104c includes a housing 104c-1, a limiting ring 104c-2 fixedly connected to the inner wall of the housing 104c-1, a limiting frame 104c-3 fixedly installed on the inner surface of the limiting ring 104c-2, and a connecting spring 104c-4 fixedly connected to the center of the limiting frame 104c-3.

[0032] The rotating assembly 104c also includes a connecting block 104c-5 inserted into the inner wall of the connecting spring 104c-4, a clamping plate 104c-6 fixedly connected to the end of the connecting block 104c-5, and an elastic rod 104c-7 fixedly installed on the side surface of the clamping plate 104c-6. The clamping plate 104c-6 is engaged with the clamping groove 104b-2.

[0033] It should be noted that when wearing the headphones, the compression spring 104b-5 pushes the clamping block 104b-6 to automatically adapt to the shape of the ear, achieving a stable clamping. When the user adjusts the headphone angle, the locking plate 104c-6 slides along the locking slot 104b-2, and the connecting spring 104c-4 provides rotational damping through elastic deformation, ensuring smooth adjustment with a tactile feedback. The limiting ring 104c-2 and the limiting frame 104c-3 work together to control the rotation angle within a reasonable range. The elastic rod 104c-7 continuously provides buffering force during rotation, ensuring both adjustment flexibility and preventing excessive rotation. Throughout the adjustment process, the connecting block 104c-5, through the elastic reset characteristic of the connecting spring 104c-4, ensures that the speaker unit 104d always maintains the optimal sound emission angle, achieving continuous sound quality optimization and a comfortable experience during dynamic wearing.

[0034] During use, the compression spring 104b-5 drives the clamping block 104b-6 to form an adaptive clamping force, ensuring a secure fit. The rotating component 104c uses a spring and clamping plate 104c-6 linkage mechanism. When the user adjusts the angle, the connecting spring 104c-4 generates controllable rotational damping, which, together with the limiting structure, achieves precise positioning at multiple levels. The speaker unit 104d maintains dynamic balance through an elastic support system, automatically fine-tuning the angle when the head moves, ensuring that the sound outlet 104f is always aligned with the ear canal. The entire system, through the synergistic action of the mechanical structure, ensures both the flexibility of 360° free rotation and the spatial stability of the speaker unit 104d, ultimately achieving a smart wearing effect, maintaining optimal sound quality and comfort even during exercise.

[0035] In summary, the spring-driven clamping system of the connecting component 104b provides adaptive fitting force to ensure a secure and comfortable fit; the elastic damping mechanism of the rotating component 104c enables stepless multi-angle adjustment and automatic reset, perfectly adapting to different ear shapes; the precisely designed limiting structure ensures rotational freedom while preventing excessive rotation; and the speaker unit 104d maintains the optimal sound emission angle through a dynamic balance system. The overall structure works in concert to eliminate adjustment noise and maintain excellent sound quality even during movement, ultimately achieving a perfect balance between comfortable wearing experience and high-quality audio performance, significantly improving user satisfaction.
