Description

Technical Field

[0001] This utility model relates to the field of noise-canceling headphone technology, specifically a noise-canceling headphone. Background Technology

[0002] In today's fast-paced life, noise-canceling headphones have become an indispensable electronic product for many consumers. Whether on a bustling subway or bus, or in an open-plan office space filled with ambient noise, noise-canceling headphones can create a quiet personal space for users with their excellent noise cancellation performance, helping users enjoy music on the go and stay focused at work.

[0003] However, existing noise-canceling headphones have revealed a series of problems that urgently need to be addressed in practical use. Because noise-canceling headphones need to fit snugly against the ear to achieve good noise cancellation, after prolonged wear, the space between the earcup and the ear can easily become a relatively sealed environment. The skin of the ear continuously dissipates heat, and in such a sealed space, heat cannot dissipate in time and will accumulate. This not only causes users to feel stuffy and uncomfortable, affecting wearing comfort, but may also adversely affect the normal metabolism of the ear skin due to excessively high local temperatures.

[0004] Meanwhile, the enclosed and warm environment becomes a breeding ground for bacteria. Sweat, oils secreted by the ears, and dust in the air all provide favorable conditions for bacterial growth. Excessive bacterial growth not only produces unpleasant odors but can also trigger ear itching, allergies, and other health problems, posing a potential threat to the user's ear health.

[0026] like Figure 1-4As shown, a noise-canceling headphone includes a headband 1, connecting arms 2 located at the bottom of both sides of the headband 1, and earcups 3 rotatably connected to the connecting arms 2. The headband 1 connects the two earcups 3 and fixes the headphones to the user's head. It has a certain degree of elasticity and adjustability to adapt to different user head sizes, ensuring stability and comfort when wearing the headphones. The connecting arms 2 connect the headband 1 to the earcups 3 and allow the earcups 3 to rotate relative to the connecting arms 2, making it convenient for the user to adjust the angle of the earcups for a better fit to the ears.

[0027] Separable earcups 4

[0028] The earcup shell 3 is equipped with a detachable earcup 4, which includes a ring-shaped ear pad 5 and a support frame 6 for supporting the ring-shaped ear pad 5. The ring-shaped ear pad 5 is in direct contact with the user's ear, providing a comfortable wearing experience and also providing some sound insulation. The support frame 6 provides support for the ring-shaped ear pad 5, ensuring that the ear pad maintains its shape during use. At the same time, the elastic outer skin of the ring-shaped ear pad 5 is attached to the support frame 6, making it easy to install and remove the ring-shaped ear pad 5.

[0029] Locking mechanism

[0030] A locking mechanism is provided between the detachable earcups 4 and the earcup shell 3. The locking mechanism includes a locking base 7 on the earcup shell 3 and a latch 8 on the support frame 6. The function of the locking mechanism is to achieve a stable connection between the detachable earcups 4 and the earcup shell 3, ensuring that the earcups will not loosen during normal use of the headphones.

[0031] Locking base 7: The locking base 7 includes a sliding sleeve 9 symmetrically arranged on the earcup shell 3 and a locking tongue 10 disposed within the sliding sleeve 9. The locking tongue 10 is a cuboid, and its interior has a through groove 20 extending horizontally. A sliding rod 21 is fixedly connected between the upper and lower walls of the through groove 20. A limiting rod 22 passing through the through groove 20 is fixedly connected between the side walls of the sliding sleeve 9. The sliding rod 21 passes through the limiting rod 22 and is slidably connected to the limiting rod 22. The sliding sleeve 9 is fixedly connected through the earcup shell 3, providing guidance for the movement of the locking tongue 10. A lock head 11 is symmetrically fixedly installed at one end of the locking tongue 10 located inside the earcup shell 3. The lock head 11 is used to cooperate with the latch 8 to realize the locking function.

[0032] Locking buckle 8: The locking buckle 8 includes locking rods 12 fixedly installed on the support frame 6, with two locking rods 12 symmetrically arranged. A limiting block 13 is provided at the end of the locking rod 12 away from the support frame 6, and a slot 14 is provided on the side of the two limiting blocks 13 that is close to each other, engaging with the locking head 11. When the detachable earcups 4 are installed on the earcup shell 3, the locking head 11 engages in the slot 14, thereby fixing the detachable earcups 4 to the earcup shell 3.

[0033] Guiding agency

[0034] The guiding mechanism includes a guide rod 15 fixedly installed on the support frame 6 and a connecting seat 16 fixedly installed on the inner wall of the earcup shell 3. The function of the guiding mechanism is to provide guidance for the detachable earcup 4 during the assembly and disassembly process, ensuring smooth operation, and also assisting the locking mechanism to ensure the accuracy of the connection between the detachable earcup 4 and the earcup shell 3.

[0035] Guide rod 15 and connecting seat 16: The connecting seat 16 has a connecting hole 17 that mates with the guide rod 15, through which the guide rod 15 slides. A limiting piece 18 is fixedly connected to the end of the guide rod 15 furthest from the supporting frame 6. The limiting piece 18 restricts the maximum distance the guide rod 15 can extend beyond the earcup shell 3, preventing it from detaching from the connecting seat 16. A push-out spring 19 is fitted onto the guide rod 15, with both ends of the spring abutting against the connecting seat 16 and the supporting frame 6, respectively. When the detachable earcup 4 is separated from the earcup shell 3, the spring force of the push-out spring 19 helps to push the detachable earcup 4 a certain distance from the earcup shell 3, facilitating user operation.

[0036] Working principle:

[0037] During normal use, manually press the locking tongue 10 to push it outwards towards the sliding sleeve 9, compressing the return spring 23. This allows the detachable earcup 4 to approach the earcup shell 3. As the detachable earcup 4 gradually approaches the earcup shell 3, the guide rod 15 slides within the connecting hole 17, acting as a guide until the detachable earcup 4 and earcup shell 3 are in contact. At this point, the locking head 11 aligns with the slot 14. Releasing the locking tongue 10 allows the spring force of the return spring 23 to reset the locking tongue 10, and the locking head 11 engages with the slot 14, completing the locking connection between the detachable earcup 4 and the earcup shell 3, creating a sealed, soundproof space. Wearing headphones at this point provides a soundproof experience.

[0038] When the ears overheat during use, the latch 10 can be pressed again until the lock head 11 disengages from the slot 14 and no longer restricts the limiting block 13. The elasticity of the spring 19 can help push the detachable earcup 4 out of the earcup shell 3 a certain distance. The limiting piece 18 is used to limit the maximum movement distance of the guide rod 15 out of the earcup shell 3 and prevent the guide rod 15 from coming out of the connecting seat 16. Since there is a certain gap between the detachable earcup 4 and the earcup shell 3, air can flow through the gap between the detachable earcup 4 and the earcup shell 3, thereby carrying away the heat emitted by the ears and realizing the heat dissipation function. This effectively reduces the stuffiness of the user's ears and does not affect the user's continued use of the headphones.
