By providing the adjusting device 5, the wearing sizes of the left earphone 1 and the right earphone 2 can be adjusted, thereby avoiding that the comfortable wearing size of the staff is larger or smaller, and the wearing sizes of the left earphone 1 and the right earphone 2 are difficult to change, resulting in the staff having to wear them forcibly, thereby causing the headband 3 to oppress the staff's head, thereby improving the comfort of the device when wearing it, and a dustproof device 6 is provided on the surface of the left earphone 1. By providing the dustproof device 6, the idle charging port 4 can be dust-proofed, thereby avoiding long-term restriction of the charging port 4, dust entering the charging port 4, resulting in the charging port 4 being covered with dust and impurities, thereby causing the charging port 4 to have poor contact, thereby improving the protection of the device.

[0029] The specific arrangement and function of the adjusting device 5 and the dust-proof device 6 will be described in detail below.

[0030] Reference Figure 2As shown, in this embodiment: the adjustment device 5 includes two fixing rods 52, both of which are fixedly connected to the arc surface of the headband 3, two adjustment plates 51 are slidably connected in the headband 3, one side of the two adjustment plates 51 is fixedly connected to the left earphone 1 and the right earphone 2 respectively, the arc surface of the fixing rod 52 is slidably connected to an operating plate 53, the side of the operating plate 53 close to the headband 3 is fixedly connected to an insertion rod 54, a plurality of jacks 55 are provided on the surface of the adjustment plate 51, and one end of the fixing rod 52 away from the headband 3 is fixedly connected to a limited The size of the positioning plate 56 and the plug rod 54 are matched with the size of the plug hole 55. When the staff pulls the operating plate 53, the operating plate 53 slides on the arc surface of the fixed rod 52. At this time, the limiting plate 56 has the effect of limiting the maximum sliding distance of the operating plate 53 on the arc surface of the fixed rod 52, thereby preventing the operating plate 53 from being separated from the arc surface of the fixed rod 52 due to excessive pulling force when the staff pulls the operating plate 53. The arc surface of the fixed rod 52 is sleeved with a first spring 57, and the two ends of the first spring 57 are respectively The first spring 57 is fixedly connected to the operating plate 53 and the headband 3. When the staff releases the operating plate 53, the resilience of the first spring 57 drives the operating plate 53 to slide on the arc surface of the fixing rod 52. At the same time, the operating plate 53 drives the insertion rod 54 to move until the insertion rod 54 is inserted into the insertion hole 55. At this time, the first spring 57 improves the stability of the insertion rod 54 when limiting the adjustment plate 51. The side of the operating plate 53 away from the insertion rod 54 is fixedly connected to the screw 58. The arc surface of the screw 58 is threadedly connected to the strip plate 59. When the staff touches the insertion rod After limiting the adjustment plate 51, continue to pull the operating plate 53 until the operating plate 53 moves to the highest point of the fixing rod 52. At this time, rotate the strip plate 59 to make the strip plate 59 move on the arc surface of the screw rod 58 until the strip plate 59 abuts against the surface of the limiting plate 56. At this time, the strip plate 59 has achieved the effect of limiting the movement of the operating plate 53, thereby preventing the staff from rubbing against the adjustment plate 51 when adjusting the wearing size of the left earphone 1 and the right earphone 2, causing the rod 54 to be damaged.

[0031] Reference Figure 3 and Figure 4As shown, specifically, the dustproof device 6 includes a support plate 61, which is fixedly connected to the surface of the left earphone 1, a sliding rod 62 is slidably inserted in the support plate 61, a connecting plate 63 is fixedly connected to the arc surface of the sliding rod 62, a dustproof plate 64 is fixedly connected to one side of the connecting plate 63, the dustproof plate 64 is slidably connected to the surface of the left earphone 1, an L-shaped plate 66 is fixedly connected to the surface of the left earphone 1, a driving rod 67 is inserted into the inner thread of the L-shaped plate 66, one end of the driving rod 67 is rotatably connected to a connecting block 68, a positioning rod 69 is fixedly connected to the side of the connecting block 68 close to the driving rod 67, the arc surface of the positioning rod 69 is slidably connected to the L-shaped plate 66, when the staff rotates the driving rod 67, the driving rod 67 moves on the inner thread of the L-shaped plate 66, and at the same time the driving rod 67 drives the connecting block 68 to move, and the connecting block 68 brings The dynamic positioning rod 69 slides in the L-shaped plate 66. At this time, the positioning rod 69 has the effect of limiting the connection block 68 from rotating with the driving rod 67, so as to increase the stability of the connection between the connection block 68 and the surface of the dustproof plate 64. The arc surface of the slide bar 62 is sleeved with a second spring 65, and the two ends of the second spring 65 are respectively fixedly connected to the slide bar 62 and the support plate 61. When the staff releases the contact of the connection block 68 with the dustproof plate 64, the rebound force of the second spring 65 drives the slide bar 62 to slide in the support plate 61. At the same time, the slide bar 62 drives the connecting plate 63 to move, and the connecting plate 63 drives the dustproof plate 64 to slide on the surface of the left earphone 1. At this time, the second spring 65 has the effect of automatically removing the dustproof plate 64 from the charging port 4, so as to reduce the staff's operating steps for the device and improve the staff's work efficiency.

[0032] Working principle: when the staff needs to adjust the wearing size of the left earphone 1 and the right earphone 2, the operating plate 53 is pulled to make the operating plate 53 slide on the arc surface of the fixed rod 52, the first spring 57 is stretched, and the operating plate 53 drives the insertion rod 54 to move until the insertion rod 54 is disengaged from the jack 55. At this time, the operating plate 53 is continued to be pulled until the operating plate 53 moves to the highest point of the fixed rod 52. At this time, the strip plate 59 is rotated to make the strip plate 59 threaded on the arc surface of the screw 58 until the strip plate 59 abuts against the surface of the limit plate 56. At this time, the left earphone 1 and the right earphone 2 are pulled, and the left earphone 1 and the right earphone 2 drive the adjustment plate 51 to slide in the headband 3 until it is adjusted to a suitable size. At this time, the strip plate 59 is rotated again to make the strip plate 59 move on the arc surface of the screw 58 until the strip plate 59 no longer abuts against the surface of the limit plate 56. At this time, the effect of adjusting the wearing size of the left earphone 1 and the right earphone 2 is achieved, avoiding the staff from having a larger or smaller comfortable wearing size, and the wearing size of the left earphone 1 and the right earphone 2 is difficult to change, resulting in the staff having to wear it forcibly, thereby causing the headband 3 to compress the staff's head, thereby improving the comfort of the device when worn.

[0033] When the staff needs to prevent dust from the idle charging port 4, they push the sliding rod 62 to make the sliding rod 62 slide in the supporting plate 61, and the second spring 65 is compressed. At the same time, the sliding rod 62 drives the connecting plate 63 to move, and the connecting plate 63 drives the dustproof plate 64 to slide on the surface of the left earphone 1 until the dustproof plate 64 covers the charging port 4. At this time, the driving rod 67 is rotated, and the driving rod 67 moves in the inner thread of the L-shaped plate 66. At the same time, the driving rod 67 drives the connecting block 68 to move, and the connecting block 68 drives the positioning rod 69 to slide in the L-shaped plate 66 until the connecting block 68 abuts against the surface of the dustproof plate 64. At this time, the effect of preventing dust from being applied to the idle charging port 4 is achieved, and the long-term restriction of the charging port 4 is avoided, and dust enters the charging port 4, resulting in the charging port 4 being covered with dust and impurities, thereby causing the charging port 4 to have poor contact, thereby improving the protection of the device.
