[0002] Headphone housings typically consist of a headband and earcups. The headband is adjustable to provide a better wearing experience. Key components are usually located inside the speakers, such as the sound unit. As the core component for generating sound, it precisely drives the diaphragm to vibrate based on electrical signals, thereby converting the electrical signals into sound waves of different frequencies and amplitudes to achieve rich and realistic sound reproduction.

[0003] Currently, the shells of over-ear headphones require special tools and careful operation to disassemble during maintenance. This process is not only cumbersome but also greatly hinders the efficient conduct of inspection and repair work. Furthermore, when disassembling manually with the aid of tools, the slightest carelessness can easily cause irreversible damage to the headphone shell, greatly increasing the difficulty and risk of maintenance and causing many inconveniences for users. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a headphone shell with advantages such as adjustable headband and easy battery replacement, thus solving the problem of inconvenient inspection and maintenance in existing technologies.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A headset shell includes a connector, a headband fixedly connected to the upper surface of the connector, a sealing strip slidably connected to one side surface of the headband, a passive locking strip fixedly connected to the lower surface of the headband, an active locking strip slidably connected to the lower surface of the passive locking strip, a flip-cover mechanism and a sliding cover mechanism on the lower surface of the connector, an earcup on one side surface of the flip-cover mechanism, and a microphone on the lower surface of the flip-cover mechanism; the flip-cover mechanism includes a locking device and a safety device, the safety device providing a fixing effect on the locking device to prevent accidental activation.

[0007] Preferably, the locking device includes a first speaker, a connector, an opening spring, a spring block, a side cover, a rotating shaft, an active locking element, a passive locking element, a disc, a slide rod, a limiting spring, and a handle. The first speaker is fixedly connected to the lower surface of the connector, the connector is fixedly connected to the inner surface of the first speaker, the opening spring is fixedly connected to one side surface of the connector, the spring block is fixedly connected to one side surface of the opening spring, the side cover is slidably connected to one side surface of the spring block, the rotating shaft is fixedly connected to one side surface of the side cover, the active locking element is fixedly connected to one side surface of the side cover, the passive locking element is fixedly connected to one side surface of the active locking element, the disc is slidably connected to the lower surface of the passive locking element, the slide rod is fixedly connected to the lower surface of the disc, the limiting spring is slidably connected to the outer surface of the slide rod, and the handle is fixedly connected to the lower surface of the slide rod.

[0008] Preferably, the safety device includes a locking ring, an arc groove, and an arc strip. The locking ring is fixedly connected to the lower surface of the passive locking member. An arc groove is formed on the inner surface of the locking ring, and an arc strip is slidably connected to the inner surface of the arc groove.

[0009] Preferably, there are two identical active card strips, which are symmetrically distributed along both sides of the passive card strip.

[0010] Preferably, the first speaker and the second speaker are the same size and are symmetrically distributed on both sides of the passive card strip.

[0011] Preferably, the device further includes a sliding cover mechanism comprising a second speaker, a battery compartment, a sliding groove, a raised strip, a cover, a locking hole, a compression spring, and a compression block. The lower surface of the connector is fixedly connected to the second speaker, the inner surface of the second speaker is fixedly connected to the battery compartment, a sliding groove is formed on one side surface of the battery compartment, a cover is slidably connected to one side surface of the battery compartment, a raised strip is fixedly connected to one side surface of the cover, a locking hole is formed on one side surface of the cover, a compression block is slidably connected to the inner side of the locking hole, and a compression spring is fixedly connected to one side surface of the compression block.

[0012] Preferably, two identical compression springs are provided, and they are symmetrically distributed along the side surface of the compression block closest to the battery compartment.

[0013] Compared with the prior art, the present invention provides a headphone shell with the following advantages:

[0014] 1. Through the design of the flip-top mechanism, rotating the handle causes the disc and slide bar to rotate. When the arc strip on the side of the disc enters the arc groove of the locking ring, pulling the handle downward causes the passive locking component to press the limiting spring downward. At the same time, the connecting component will limit it. When the passive locking component moves down and leaves the active locking bar, the opening spring will immediately open the side cover through the spring block. At the same time, the side cover will rotate around the center of the rotating shaft to complete the opening. The convenient opening method not only saves maintenance time but also reduces maintenance costs, significantly improving the user's experience in headphone maintenance.

[0015] 2. With the sliding cover mechanism, the battery compartment can be opened. The sliding cover moves the convex strip horizontally along the slide groove. When the cover slides, the locking hole on the cover moves synchronously, forcing the compression block and compression spring to compress, so that the cover leaves the slide groove and exposes the battery compartment. The operation is simple and users do not need to use any additional tools. They can easily open the battery compartment with just one hand, which greatly improves the efficiency of battery replacement. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A headset shell includes a connector 1, a headband 2 fixedly connected to the upper surface of the connector 1, a sealing strip 3 slidably connected to one side surface of the headband 2, a passive locking strip 5 fixedly connected to the lower surface of the headband 2, an active locking strip 4 slidably connected to the lower surface of the passive locking strip 5, a flip-top mechanism 6 and a sliding mechanism 7 on the lower surface of the connector 1, an earcup 8 on one side surface of the flip-top mechanism 6, and a microphone 9 on the lower surface of the flip-top mechanism 6.

[0024] The flip mechanism 6 includes a locking device and a safety device.

[0025] In this embodiment, the locking device includes a first speaker 601, a connector 602, a cover-opening spring 603, a spring block 604, a side cover 605, a rotating shaft 606, an active locking component 607, a passive locking component 608, a disc 612, a sliding rod 613, a limiting spring 614, and a handle 615. The first speaker 601 is fixedly connected to the lower surface of the connector 601, the connector 602 is fixedly connected to the inner surface of the first speaker 601, the cover-opening spring 603 is fixedly connected to one side surface of the connector 602, and a limiting spring 614 is fixedly connected to one side surface of the cover-opening spring 603. A spring block 604 has a side cover 605 slidably connected to one side surface of the spring block 604. A rotating shaft 606 is fixedly connected to one side surface of the side cover 605. An active locking element 607 is fixedly connected to one side surface of the active locking element 607. A passive locking element 608 is fixedly connected to one side surface of the active locking element 607. A disc 612 is slidably connected to the lower surface of the passive locking element 608. A slide rod 613 is fixedly connected to the lower surface of the disc 612. A limiting spring 614 is slidably connected to the outer surface of the slide rod 613. A handle 615 is fixedly connected to the lower surface of the slide rod 613. Pulling the handle 615 downwards causes the passive latch 608 to press the limiting spring 614 downwards, while the connecting piece 602 limits its movement. When the passive latch 608 moves downwards away from the active latch 4, the opening spring 603 will spring open the side cover 605 through the spring block 604. At the same time, the side cover 605 will rotate around the center of the rotating shaft 606, completing the opening. This allows maintenance personnel to perform repairs quickly without the need for complicated operations using tools, effectively reducing the risk of damage to parts during disassembly.

[0026] Furthermore, the safety device includes a locking ring 609, an arc groove 610, and an arc strip 611. The locking ring 609 is fixedly connected to the lower surface of the passive locking member 608. The arc groove 610 is formed on the inner surface of the locking ring 609, and the arc strip 611 is slidably connected to the inner surface of the arc groove 610. Rotating the handle 615 causes the disc 612 and the slide rod 613 to rotate. When the arc strip 611 on the side of the disc 612 enters the arc groove 610 formed by the locking ring 609, the slide rod 613 and the passive locking member 608 are linked, effectively avoiding accidental contact during daily use of the headphones, which could lead to the exposure of the maintenance port and the resulting accidental risk.

[0027] Furthermore, there are two identical active locking strips 4, symmetrically distributed along both sides of the passive locking strip 5. Pulling the two connecting pieces 1 causes the active locking strips 4 and the sealing strips 3 on both sides to slide on the upper surface of the passive locking strip 5, while the headband 2 provides support, allowing the gap between the first speaker 601 and the second speaker 701 to expand or shrink, better conforming to the user's head shape and providing a better wearing experience.

[0028] Furthermore, the first speaker 601 and the second speaker 701 are the same size and are symmetrically distributed on both sides of the passive retaining strip 5. In use, the first speaker 601 and the second speaker 701 play music through the earcups 8. The symmetrically distributed speakers allow the overall weight of the headphones to be evenly distributed on both sides of the ears, effectively avoiding the feeling of pressure on one side caused by uneven weight distribution, and greatly improving the comfort of wearing for a long time.

[0029] In addition, it also includes a sliding cover mechanism 7, which includes a second speaker 701, a battery compartment 702, a slide groove 703, a protrusion 704, a cover 705, a locking hole 706, a compression spring 707, and a compression block 708. The second speaker 701 is fixedly connected to the lower surface of the connector 1. The battery compartment 702 is fixedly connected to the inner surface of the second speaker 701. A slide groove 703 is opened on one side surface of the battery compartment 702. The cover 705 is slidably connected to one side surface of the battery compartment 702. A protrusion 704 is fixedly connected to one side surface of the cover 705. A locking hole 706 is opened on one side surface of the cover 705. The compression block 708 is slidably connected to the inner side of the locking hole 706. A compression spring 707 is fixedly connected to one side surface of the compression block 708. The sliding cover 705 causes the protrusion 704 to move horizontally along the slide groove 703. When the cover 705 slides, the locking hole 706 opened on the cover 705 moves synchronously, forcing the compression block 708 and the compression spring 707 to compress. The cover 705 leaves the slide groove 703, exposing the battery compartment 702 for easy battery replacement. In daily frequent use, it is not easy to loosen or shift, ensuring the long-term stability of the opening and closing function of the battery compartment 702.

[0030] It is worth noting that there are two identical compression springs 707, symmetrically distributed along the surface of the compression block 708 near the battery compartment 702. The compression springs 707 and the compression block 708 pass through the locking hole 706 to fix the cover 705. The symmetrical distribution of the compression springs 707 makes the compression block 708 more evenly stressed, making the cover 705 less prone to shaking, improving the sealing performance, effectively blocking dust and moisture, and extending the battery life.

[0031] In use, firstly, by pulling the two connecting parts 1, the active locking strips 4 and sealing strips 3 on both sides move above the passive locking strip 5. At the same time, the headband 2 above provides support, allowing the distance between the first speaker 601 and the second speaker 701 to be adjusted. When the headphones need to replace the battery, the battery compartment 702 is opened through the sliding cover mechanism 7, and the cover 705 is pushed to move the protrusion 704 horizontally along the slide groove 703. When the cover 705 slides, the locking holes 706 opened in the cover 705 will move synchronously, forcing the pressure... The compression block 708 and compression spring 707 compress and push the cover 705 away from the slide groove 703 to expose the battery compartment 702 for easy battery replacement. When the headphones malfunction, the flip cover mechanism 6 can be used for quick repair. Rotating the handle 615 causes the disc 612 and slide bar 613 to rotate. When the arc strip 611 on the side of the disc 612 enters the arc groove 610 opened by the locking ring 609, the handle 615 is pulled downward, causing the passive locking piece 608 to press the limiting spring 614 downward. At the same time, the connecting piece 602 will limit it. When the passive locking piece 608 moves down away from the active locking piece 4, the opening spring 603 will immediately cause the spring block 604 to pop open the side cover 605. At the same time, the popped-open side cover 605 will rotate around the center of the rotating shaft 606 to complete the opening, allowing maintenance personnel to check the internal condition of the first speaker 601.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
