Positioning blocks 208 are provided on both side walls of the movable plate 205, and positioning grooves 20 for sliding of the positioning blocks 208 are provided on the inner wall of the sliding groove 202. 7. When it is necessary to adjust the angle of the earcup body 3, pull the movable plate 205. The movable plate 205 slides in the slide groove 202, compressing the spring 203. At the same time, the telescopic sleeve 204 retracts, and the movable plate 205 drives the locking rod 206 to disengage from the locking groove 201. At this time, the connecting shaft 2 can be rotated to rotate the earcup body 3 to a suitable angle. Release the movable plate 205. Under the elastic force of the spring 203, the movable plate 205 returns to its original position, driving the locking rod 206 to re-engage in the corresponding locking groove 201, thereby fixing the angle of the earcup body 3. During the sliding process of the movable plate 205, the positioning block 208 slides in the positioning groove 207, playing a guiding and stabilizing role, ensuring the smoothness of the sliding of the movable plate 205.
[0027] Through the cooperation of the connecting shaft 2, locking groove 201, locking rod 206 and elastic components, the angle of the earcup body 3 can be flexibly adjusted and stably fixed. Users can adjust the angle of the earcup body 3 according to their own needs and wearing habits to improve wearing comfort. By adjusting the angle of the earcup body 3, it can better fit the user's ear, reduce the entry of external noise from the gap between the earcup and the ear, thereby enhancing the noise reduction effect. The operation is convenient and quick.
[0028] In a preferred embodiment, the mounting ring 303, the filter plate 302, and the earcup body 3 are locked together by threaded bolts 304. The guide shell 301 has an open structure with the opening aligned with the sound outlet. A Velcro body 4 is fixed to the surface of the mounting ring 303. The sponge ring 5 is detachably connected to the mounting ring 303 via the Velcro body 4. The rubber sound insulation block 502 has a wavy structure. The mounting ring 303, the filter plate 302, and the earcup body 3 are locked together by threaded bolts 304. The filter plate 302 is placed on the surface of the earcup body 3, and the mounting ring 303 is aligned with the edge of the earcup body 3. Then, the three are fixed together using threaded bolts 304. At the same time, the sponge ring 5 is detachably connected to the mounting ring 303 via the Velcro body 4. The side of the sponge ring 5 with Velcro is aligned and attached to the Velcro body 4 on the surface of the mounting ring 303 to complete the installation.
[0029] External noise first comes into contact with the filter plate 302, which initially filters larger dust and impurities to prevent them from entering the earcups and affecting the performance of the sound unit. Then, the noise enters the sound insulation groove 501 of the foam ring 5. The rubber sound insulation block 502 inside the sound insulation groove 501 has a wave-like structure, which increases the number of reflections and scatterings of noise, so that the energy of the noise is continuously consumed during propagation, thereby reducing the intensity of the noise. When the foam ring 5 becomes dirty due to long-term use or the noise reduction effect decreases, the user can easily tear the foam ring 5 off the mounting ring 303 and replace it with a new foam ring 5. This is convenient and quick, reducing maintenance costs. The foam ring 5 and the rubber sound insulation block 502 further absorb and attenuate the noise, forming a multi-layered noise reduction system that effectively reduces the impact of external noise on the user's auditory experience. The foam ring 5 and the mounting ring 303 are detachably connected, allowing users to easily replace the foam ring 5 without the need for professional tools and techniques, reducing maintenance difficulty and costs.
[0030] The guide shell 301 has an open structure and is aligned with the sound outlet, which can guide the sound emitted by the headphones to be transmitted smoothly. At the same time, it can concentrate the sound to a certain extent, reduce the sound diffusion to the surroundings, and improve the clarity and sound quality of the sound.
[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0032] During operation, for the adjustment components, when the user needs to adjust the angle of the earcup body 3, the movable plate 205 is manually pulled. The movable plate 205 slides within the slide groove 202 inside the headband body 1. The positioning blocks 208 on both sides of the movable plate 205 slide synchronously within the positioning grooves 207 on the inner wall of the slide groove 202, providing guidance and stability to ensure the smooth movement of the movable plate 205. During the sliding process, the movable plate 205 compresses the spring 203 at one end of the slide groove 202, and at the same time, the telescopic sleeve 204 of the inner ring of the spring 203 retracts accordingly. Since the movable plate 205 is fixedly connected to the locking rod 206, the movable plate 205... The movement of 5 causes the locking rod 206 to disengage from the corresponding locking groove 201 on the outer wall of the connecting shaft 2. At this time, the connecting shaft 2 can rotate freely. The user rotates the connecting shaft 2, causing the earmuff body 3 to rotate to a suitable angle. Then, the movable plate 205 is released. Under the elastic force of the spring 203, the movable plate 205 returns to its original position, causing the locking rod 206 to re-engage into the corresponding locking groove 201, thus achieving stable fixation of the earmuff body 3 angle. For the noise reduction component, the mounting ring 303, the filter plate 302, and the earmuff body 3 are locked together by the threaded bolt 304. The filter plate 302 is placed in the earmuff.

Align and attach the side of the foam ring 5 with the Velcro to the Velcro main body 4 to complete the installation. External noise first comes into contact with the filter plate 302, which performs preliminary filtering of larger dust and impurities to prevent them from entering the earcup and affecting the performance of the sound unit. Subsequently, the noise enters the sound insulation groove 501 of the foam ring 5, and the sound insulation groove 501 is evenly... The evenly distributed, wave-shaped rubber sound-absorbing blocks 502 increase the number of times noise is reflected and scattered, so that the noise energy is continuously consumed during the propagation process, thereby reducing the noise intensity. The earcup body 3 has an open structure inside, and the opening is aligned with the sound outlet guide shell 301, which can guide the sound emitted by the headphones to be transmitted smoothly and play a certain role in focusing the sound, reducing the sound diffusion to all directions, and improving the clarity and sound quality. When the foam ring 5 becomes dirty due to long-term use or the noise reduction effect decreases, the user can easily tear the foam ring 5 off the mounting ring 303 and replace it with a new foam ring 5.
