Technical Field
[0001] This utility model relates to the field of headphone technology, and in particular to a headphone with interchangeable earcups. Background Technology
[0002] Over-ear headphones, as the name suggests, are worn on the head and not inserted into the ear canal. Unlike in-ear earbuds, they consist of two parts: a signal transmitter and a headphone (usually a dynamic driver) with a signal receiver and amplifier. The headphone part is mostly a ring-shaped foam block, with the sound-producing component installed in the center of the foam block. The foam block fits against the skin outside the ear, which can improve the comfort during wearing and also provide noise isolation.
[0003] The applicant discovered through a search that a Chinese patent discloses "A Bluetooth Headset with Easily Replaceable Earcups," with publication (announcement) number "CN216795258U." This patent mainly allows the user to remove the retaining ring simply by removing the screws from the fixing ring and the headphone body. However, this device requires tools (such as screwdrivers) to remove the screws, resulting in multiple steps and a poor user experience. Each time the earcups are replaced, multiple screws need to be removed and reinstalled, which is time-consuming and laborious. This is not efficient for users or scenarios that require frequent earcup replacement. Therefore, we propose a headset with interchangeable earcups. Utility Model Content

The pin 14 is fixedly installed at the bottom end of the elastic headband 11, and the hinge seat 13 is fixedly installed on one side of the fixing sleeve 12. The pin 14 extends into the hinge seat 13, and the elastic headband 11 is connected to the hinge seat via the pin 14. The 13-rotatable connection and telescopic structure 2 include a sound-generating part 21, a first sliding groove 22, a cavity 23 and a slide rail 24. The cavity 23 is located inside the fixed sleeve 12. The slide rail 24 is fixedly installed on the inner wall of the cavity 23. The first sliding groove 22 is opened on one side of the sound-generating part 21. The first sliding groove 22 extends into the slide rail 24 and is slidably connected to the slide rail 24. The top of the fixed sleeve 12 is threaded with a limiting bolt 25, which limits the sound-generating part 21.
[0026] Specifically, the sound-producing part 21 can slide in the fixed sleeve 12 and the telescopic length can be adjusted by the limiting bolt 25. Users can flexibly adjust it according to head size, ear position and wearing habits to improve wearing comfort. The limiting bolt 25 is simple and intuitive to operate, adapts to different head shapes and ear positions, and expands the range of applicable people.
[0027] Example 2:
[0028] Please see the appendix Figure 5 - Appendix Figure 8 The switching structure 3 includes a mounting cavity 301 and a second sliding groove 302. The mounting cavity 301 is located inside the sound-emitting part 21, and the second sliding groove 302 is located on the side wall of the mounting cavity 301. An earmuff 303 is installed inside the mounting cavity 301, and a slider 305 is fixedly installed on the earmuff 303. The slider 305 extends into the second sliding groove 302, and the slider 305 and the second sliding groove 302 are slidably connected. A soft pad 304 is fixedly installed on one side of the earmuff 303, and a limiting hole 306 is provided at the top of the earmuff 303. The top of the sound-emitting part 21 is located at... An installation groove 307 is provided, and a pull rod 309 is provided in the installation groove 307. The pull rod 309 passes through the sound-emitting part 21 and extends to the top of the sound-emitting part 21. The pull rod 309 is slidably connected to the sound-emitting part 21. A limiting post 308 is fixedly installed at the bottom end of the pull rod 309. The limiting post 308 and the limiting hole 306 cooperate. A spring 310 is sleeved on the pull rod 309. One end of the spring 310 is fixedly connected to the limiting post 308, and the other end of the spring 310 is fixedly connected to the top wall of the sound-emitting part 21. A turntable 311 is fixedly installed at the top end of the pull rod 309.
[0029] Specifically, by setting the switching structure 3, the turntable 311 drives the pull rod 309 to disengage the limiting post 308 from the limiting hole 306 on the earcup 303, while compressing the spring 310, making it easy to remove the earcup 303. When replacing, the user only needs to pull the turntable 311 to easily remove and install the earcup 303. The operation is simple and suitable for scenarios where the earcup 303 is frequently replaced. It effectively avoids the problem of improper fixation and improves safety and stability.
[0030] The working principle of this utility model is as follows: This utility model is a headphone with interchangeable earcups. When worn, rotating the fixed sleeve 12 causes the hinge seat 13 to rotate on the pin 14, thereby adjusting the angle of the fixed sleeve 12 and thus the angle of the telescopic structure 2 and the switching structure 3, making it easier for the user to wear. Rotating the limiting bolt 25 causes the limiting bolt 25 to move threadedly in the fixed sleeve 12, so that the limiting bolt 25 no longer limits the sound-emitting part 21. Then, pulling the sound-emitting part 21 causes it to slide on the slide rail 24 through the first slide groove 22, thereby extending and then retracting the sound-emitting part 21. Finally, tightening the limiting bolt 25 causes the limiting bolt 25 to rotate and limit the sound-emitting part 21 again, thereby adjusting the telescopic length of the sound-emitting part 21 to suit different users.
[0031] When the soft cover 304 needs to be replaced, pull the turntable 311. The turntable 311 moves the limiting post 308, and at the same time, the limiting post 308 compresses the pull rod 309. When the limiting post 308 disengages from the limiting hole 306, pull the soft cover 304. The soft cover 304 moves the earmuff 303 and the slider 305 from the second slide groove 302, thereby removing the soft cover 304. After replacement, align the slider 305 on the earmuff 303 with the second slide groove 302, push the soft cover 304, so that the earmuff 303 is completely fitted with the mounting cavity 301. At this time, the limiting hole 306 is aligned with the limiting post 308. Release the turntable 311, and the limiting post 308 automatically resets under the elastic force of the spring 310, so that the limiting post 308 extends into the limiting hole 306, thereby re-limiting the earmuff 303 and realizing the installation of the soft cover 304.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
