Description

Technical Field

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

[0002] Noise-isolating earmuffs are tools used to protect users' hearing and enjoy a quiet environment. Headphones with noise-isolating earmuffs have a greater advantage in noise isolation, better blocking out external noise and allowing users to listen to music or audio content more clearly.

[0003] Existing earcups are attached to headphones using an adhesive method. When the leather material on the surface of the earcup is damaged, or the internal sound-absorbing foam fails to rebound, the entire headphone must be discarded, thus increasing the cost of using headphones. Therefore, there is a need to provide a sound-isolating earcup and a headphone with the sound-isolating earcup, so that the sound-isolating earcup can be quickly separated from the headphone. The structure should be flexible, detachable, and have low maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a soundproof earmuff and a headphone with the soundproof earmuff, in order to solve the problem mentioned in the background art, where the existing earmuffs are connected to the headphone by adhesive. When the leather material on the surface of the earmuff is damaged, or the internal sound-insulating foam cannot rebound, the entire headphone must be discarded, thereby increasing the cost of using the headphone.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a soundproof earmuff, comprising:

[0007] The mounting assembly includes a mounting plate, an earmuff body, a mounting groove, a fixing frame, and a fixing post. The earmuff body is attached to the outer surface of the mounting plate, the mounting groove is formed inside both ends of the mounting plate, the fixing post is fixed to the inner surface of the mounting groove, and the fixing frame is fitted onto the outer surface of the fixing post.

[0008] Furthermore, the fixing column and the fixing frame are provided with through mounting holes, and mounting columns are installed inside the mounting holes.

[0009] Furthermore, a spring is fixed inside the mounting column, a movable plate is fixed on the upper surface of the spring, and a limit post is fixed on the upper surface of the movable plate. The limit post is connected through the top of the fixed column and the fixed frame.

[0010] This utility model also provides a headset with noise-isolating earcups, the headset including noise-isolating earcups and protective components:

[0011] The protective assembly includes an earphone body, a protective plate, a sealing ring, and a movable frame; the earphone body is fixed to the outer surface of the fixed frame, the sealing ring is snapped into the inside of the mounting groove, the protective plate is fixed to the outer surface of the sealing ring, the movable plate of the sound-isolating earcups is connected through the inside of the protective plate, and the movable frame is fixed to the outer surface of the mounting plate.

[0012] Furthermore, a limiting plate is connected through the interior of the movable frame, the bottom of which is locked inside the protective plate, and a limiting groove is provided inside the movable frame.

[0013] Furthermore, a limiting rod is fixed to the outer surface of the top of the limiting plate. The limiting rod is located inside the limiting groove, and a silicone column is fixed to the lower surface of the limiting rod. The silicone column is stuck inside the movable frame.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through its designed installation components, allows for quick replacement of damaged earmuffs when a downward pressing force is applied to the movable plate. When the spring is compressed, it causes the limiting post to disengage from the fixed post and the fixed frame. A pulling force is then applied to the mounting post, pulling it out of the mounting hole. A relative pulling force is then applied to the mounting plate and the headphone body, causing the fixed post to separate from the fixed frame. The mounting plate with the new earmuff body is then aligned with the headphone body, and the fixed post is inserted into the fixed frame. The mounting post is then inserted into the mounting hole using the same method, ensuring the limiting post passes through the fixed frame. This solution allows for rapid separation of the earmuffs from the headphones, is flexible and detachable, and has low maintenance costs.

[0016] Second, based on the first beneficial effect, when the mounting plate is fixed in the required position with the help of the protective components, an upward pushing force is applied to the limiting rod, causing the limiting plate to retract into the movable frame. Then, the protective plate is aligned with the mounting groove, so that the sealing ring is inserted into the mounting groove. A downward pushing force is applied to the limiting rod, and when the silicone column is inserted into the movable frame, the limiting plate can be inserted into the protective plate. This solution can effectively protect the components inside the mounting groove and prevent external impurities from entering the mounting groove. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. 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.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figures 1-4 As shown, this embodiment is a noise-isolating earmuff, comprising:

[0029] The mounting components include a mounting plate 11, an earmuff body 12, a mounting groove 13, a fixing frame 14, and a fixing post 15. The earmuff body 12 is attached to the outer surface of the mounting plate 11, the mounting groove 13 is formed inside both ends of the mounting plate 11, the fixing post 15 is fixed to the inner surface of the mounting groove 13, and the fixing frame 14 is sleeved on the outer surface of the fixing post 15.

[0030] Mounting plate 11 serves as the carrier of earcup body 12 and is the basic component for mounting earcup body 12 onto headphone body 21. Earcup body 12 effectively blocks external noise and reduces the impact of noise on the user's hearing through internal sound insulation material. At the same time, its shape design conforms to the contour of the human ear, ensuring wearing comfort. Mounting slot 13 is used to support and install fixing post 15. Through the connection between fixing post 15 and fixing frame 14, earcup body 12 and headphone body 21 are connected together.

[0031] The fixing post 15 and the fixing frame 14 are provided with a through mounting hole 151, and the mounting hole 151 is provided with a mounting post 16.

[0032] Mounting hole 151 is used for mounting post 16 to pass through its interior. Mounting post 16 is used to position the limiting post 19. When mounting post 16 is inserted into mounting groove 13 and cannot move, the limiting post 19 is moved to the desired position.

[0033] A spring 17 is fixed inside the mounting column 16. A movable plate 18 is fixed on the upper surface of the spring 17. A limit post 19 is fixed on the upper surface of the movable plate 18. The limit post 19 is connected through the top of the fixed column 15 and the fixed frame 14.

[0034] Spring 17 provides elastic force to movable plate 18. When pressure is applied to movable plate 18, spring 17 is compressed and stores elastic potential energy. When the pressure is released, spring 17 releases elastic potential energy and pushes movable plate 18 to reset. Movable plate 18 supports spring 17 and then supports limit post 19. Limit post 19 is used to restrict fixed post 15 inside fixed frame 14.

[0035] Working principle: When it is necessary to replace the damaged earmuffs, first apply a downward pressing force to the movable plate 18. When the spring 17 is in a compressed state, it drives the limiting post 19 to disengage from the fixed post 15 and the fixed frame 14. Apply a pulling force to the mounting post 16 and pull the mounting post 16 out of the mounting hole 151. Then apply a relative pulling force to the mounting plate 11 and the headphone body 21 to separate the fixed post 15 from the fixed frame 14. Align the mounting plate 11 with the new earmuff body 12 with the position of the headphone body 21, insert the fixed post 15 into the fixed frame 14, and then insert the mounting post 16 into the mounting hole 151 in the same way as described above, so that the limiting post 19 passes through the fixed frame 14.

[0036] This step quickly separates the noise-isolating earcups from the headphones, and the flexible, detachable structure results in low maintenance costs.

[0037] Please see Figures 1-4As shown, this embodiment is a headphone with noise-isolating earmuffs, including the aforementioned noise-isolating earmuffs and protective components. The protective components include a headphone body 21, a protective plate 22, a sealing ring 23, and a movable frame 24. The headphone body 21 is fixed to the outer surface of the fixed frame 14, the sealing ring 23 is snapped into the inside of the mounting groove 13, the protective plate 22 is fixed to the outer surface of the sealing ring 23, the movable plate 18 of the noise-isolating earmuffs is connected through the inside of the protective plate 22, and the movable frame 24 is fixed to the outer surface of the mounting plate 11.

[0038] The headphone body 21 is the core component of the headphone, used to play sound. It converts electrical signals into sound signals, allowing users to hear music and make calls. The protective plate 22 can prevent external impurities from entering the mounting groove 13. The sealing ring 23 can make the protective plate 22 more stably fixed in the required position. The movable frame 24 is used to limit the plate 25 to move up and down inside it.

[0039] A limiting plate 25 is connected through the interior of the movable frame 24. The bottom of the limiting plate 25 is stuck inside the protective plate 22. A limiting groove 26 is opened inside the movable frame 24.

[0040] The limiting plate 25 is used to restrict the protective plate 22 to the required position, and the limiting groove 26 is used to limit the movement of the limiting rod 27 inside it, thereby limiting the movement direction and range of the limiting plate 25.

[0041] A limiting rod 27 is fixed to the top outer surface of the limiting plate 25. The limiting rod 27 is located inside the limiting groove 26. A silicone pillar 28 is fixed to the lower surface of the limiting rod 27. The silicone pillar 28 is stuck inside the movable frame 24.

[0042] The limiting rod 27 facilitates the movement of the limiting plate 25 to the desired position, while the silicone pillar 28 is used to stably fix the limiting plate 25 in the desired position.

[0043] Working principle: After the mounting plate 11 is fixed in the required position, an upward pushing force is applied to the limiting rod 27, causing the limiting plate 25 to retract into the movable frame 24. Then, the protective plate 22 is aligned with the mounting groove 13, so that the sealing ring 23 is inserted into the mounting groove 13. A downward pushing force is applied to the limiting rod 27, and when the silicone column 28 is inserted into the movable frame 24, the limiting plate 25 can be inserted into the protective plate 22.

[0044] This step effectively protects the components inside the mounting slot 13, preventing external impurities from entering the mounting slot 13.
