[0027] The embodiment of the utility model provides a head-mounted flat-panel headset with an elastic coating.

[0028] See also Figure 1 and Figure 2 , including two earphone shells 1, the outer surface of the earphone shell 1 is equipped with volume plus and minus buttons, which is convenient for the user to adjust the volume of the earphone shell 1, and the bottom surface of the earphone shell 1 is also provided with a USB charging port, which is convenient for charging the device through a data cable.

[0029] See also Figure 1 , Figure 3 and Figure 4An adjustment block 2 is arranged on the top of each earphone housing 1, and a support rod 4 is slidably connected inside the adjustment block 2. The clamping claw 301 is adapted to the support rod 4. When the adjustment block 2 slides on the support rod 4, the head diameter of the headband 5 can be changed, so that the device is suitable for people of different physiques, thereby improving the applicability of the device.

[0030] See also Figure 1 and Figure 3 A headband 5 is provided above the two adjustment blocks 2, and the two ends of the headband 5 are respectively fixedly connected to the two adjustment blocks 2. Through the setting of the headband 5, the device can fit the user's head when worn, so that the device remains stable and avoids shaking that affects the user's experience.

[0031] The top surface of the earphone housing 1 is fixedly connected with a fixed block 6, which is fixedly connected to the bottom end of the support rod 4. The fixed block 6 provides support and stability for the support rod 4. There is also friction between the adjustment block 2 and the support rod 4, which can prevent the adjustment block 2 from sliding on the support rod 4 due to gravity.

[0032] See also Figure 1 and Figure 2 A sealing pad 7 is arranged on the outside of the earphone housing 1, and an earphone inner cover 8 is fixedly connected to the inner wall of the sealing pad 7, and a resonance layer 9 is fixedly connected to the inner wall of the earphone inner cover 8. Through the setting of the resonance layer 9, the air turbulence and reflection between the magnet gaps can be optimized and improved, making the magnet invisible in the sound wave cotton twist to obtain a purer and complete sound. Through the setting of the sealing pad 7, it is convenient for users to wear the device, and at the same time it can also provide a sound insulation effect to improve the user's auditory enjoyment.

[0033] A sound insulation pad 10 is fixedly connected to the inner wall of the earphone housing 1, and a PCB board 11 is arranged on the outside of the sound insulation pad 10. The sound insulation pad 10 can prevent the earphone volume from being too loud and affecting the external environment. The PCB board 11 is a prior art and will not be described in detail in this application.

[0034] A connecting plate 12 is arranged on the outside of the PCB board 11, a speaker 13 is fixedly connected to the inside of the connecting plate 12, and a sound amplification layer 14 is arranged on the outside of the connecting plate 12. The speaker 13 and the sound amplification layer 14 are both existing technologies and will not be described in detail in this application. By setting the speaker 13 and the sound amplification layer 14, the sound effect of the device can be enhanced and the wearer's auditory experience can be improved.

[0035] A fixing plate 15 is provided on the outside of the sound amplification layer 14, and a group of screws 16 are connected to the internal threads of the fixing plate 15. The screws 16 pass through the fixing holes left on the surface of the earphone housing 1, the sound insulation pad 10, the PCB board 11, the connecting plate 12 and the sound amplification layer 14 and are threadedly connected to the fixing plate 15, which facilitates the assembly and disassembly of the device and reduces the difficulty of disassembly for maintenance personnel.

[0036] The outer surface of the earphone housing 1 is fixedly connected with a snap-in plate 17, which is snap-fitted with a slot provided on the surface of the earphone inner cover 8. The assembler first assembles the earphone housing 1 with the fixed plate 15, and then snap-fits the earphone housing 1 with the earphone inner cover 8 through the snap-in plate 17. This completes the assembly of the device, reducing the workload of installing and disassembling the device.

[0037] A decorative plate 18 is provided outside the screw 16, and the decorative plate 18 is snap-fitted to the earphone housing 1 to cover the screw 16. The outer surface of the decorative plate 18 is engraved with a device logo and a decorative logo, which can increase the aesthetics of the earphone.

[0038] The outer surface of the decorative plate 18 is fixedly connected with an elastic coating 19. The elastic coating 19 is a prior art and will not be described in detail in this application. The elastic coating 19 has the advantages of long-lasting maintenance, low cost, high hardness, and low damage to the headphone surface paint. It can protect the surface of the headphone and reduce damage to the headphone caused by bumps and other factors. The elastic coating 19 is made of transparent material and does not affect the display effect of the decorative plate 18.

[0039] See also Figure 3 and Figure 4 Two clamping mechanisms 3 are arranged inside each adjustment block 2. The clamping mechanism 3 includes a clamping claw 301. The inner wall of the clamping claw 301 is covered with a rubber layer, which can increase the friction between the clamping claw 301 and the support rod 4 and provide a buffering effect for the contact between the two, thereby avoiding long-term wear and reducing the service life of the lever 303 and the support rod 4.

[0040] The outer surface of the clamping claw 301 is fixedly connected to the sliding rod 302, and the outer surface of the sliding rod 302 is fixedly connected to the lever 303. The lever 303 is made of steel and is not easy to deform. When one end of the lever 303 is pushed, the other end can be driven to move in the same horizontal state, reducing the inclination of the lever 303 itself and avoiding the situation where the lever 303 breaks from the sliding rod 302 under long-term use.

[0041] The inner wall of the adjustment block 2 is fixedly connected with a sleeve 304, and the sliding rod 302 is slidably connected to the sleeve 304. When the user pushes the lever 303, the lever 303 can drive the sliding rod 302 to slide inside the sleeve 304, so that the clamping claw 301 is away from the support rod 4. At this time, the adjustment block 2 can slide inside the support rod 4 so that the user can adjust the diameter of the headband 5.

[0042] A return spring 305 is fixedly connected to the inner wall of the sleeve 304, and the return spring 305 is fixedly connected to the sliding rod 302. Through the setting of the sleeve 304, the sliding rod 302 can be pushed to reset, so that the clamping claw 301 maintains the clamping effect on the support rod 4, avoiding the adjustment block 2 from sliding on the support rod 4 and affecting the wearer's experience.

[0043] When the utility model is in use: when the user wears the device, first use two fingers to simultaneously push the two levers 303, the lever 303 can drive the sliding rod 302 to slide inside the sleeve 304, so that the clamping claw 301 is away from the support rod 4, and the connecting plate 12 can slide on the support rod 4. The user slides the adjustment block 2 according to his own body shape to adjust the diameter of the headband 5. After the adjustment is completed, the lever 303 is released, and the sliding rod 302 slides and resets under the push of the sleeve 304, thereby pushing the clamping claw 301 to clamp the support rod 4, so that the adjustment block 2 remains stable on the support rod 4, avoiding the user's self-sliding on the support rod 4 due to exercise or other activities during wearing, thereby improving the wearing stability of the device.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
