DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides a technical solution: a headset clamping force tension adjustment structure, comprising a headband 1, a headset body 2 is installed at both ends of the headband 1, an adjustment component 5 for adjusting the tightness of the headband 1 is installed inside the headband 1, the adjustment component 5 comprises a fixing belt 505, an adjustment belt 502 and two limit blocks 504, the two limit blocks 504 are fixed inside the headband 1, a support belt 506 and a connecting belt 507 are connected between the two limit blocks 504, one end of the fixing belt 505 is connected to one end of the headband 1, and the other end of the fixing belt 505 passes through one of the limit blocks Block 504 extends between the support belt 506 and the connecting belt 507, one end of the adjustment belt 502 is connected to the other end of the headband 1, the other end of the adjustment belt 502 passes through another limit block 504 and extends between the support belt 506 and the connecting belt 507, and the other end of the adjustment belt 502 is provided with a serrated section 503, a screw rod 508 is rotatably installed in the middle part of the headband 1, one end of the screw rod 508 passes through the support belt 506 and is rotatably connected to the connecting belt 507, and the thread of the screw rod 508 is meshed with the teeth of the serrated section 503, and the other end of the screw rod 508 is installed with an adjustment knob 501.

[0022] When in use, the headband 1 is put on the head, and then the adjusting knob 501 is rotated to rotate the screw rod 508, so that the screw rod 508 drives the sawtooth segment 503 to move. Figure 4 As shown, the screw rod 508 is located at one end of the sawtooth segment 503 close to the fixing belt 505. At this time, the adjustment belt 502 is in conflict with the fixing belt 505, and the tightness of the headband 1 is the tightest state, as shown in FIG. Figure 5 As shown, the screw 508 is located at one end of the serrated segment 503 away from the fixed band 505, and there is a certain distance between the adjustment band 502 and the fixed band 505. At this time, the tightness of the headband 1 is in the loosest state. The tightness of the headband 1 can be adjusted by moving the serrated segment 503 to make it suitable for users with different head shapes.

[0023] A through hole is formed on another limit block 504 for the adjusting belt 502 to pass through, and the adjusting belt 502 is slidably connected in the through hole. The sliding connection between the limit block 504 and the adjusting belt 502 limits the moving direction of the adjusting belt 502, so that the adjusting belt 502 can move along a horizontal track.

[0024] An anti-slip block 509 is fixed to one end of the adjusting belt 502. When the screw rod 508 is located at one end of the sawtooth section 503 close to the fixing belt 505, the anti-slip block 509 interferes with the other end of the fixing belt 505. When the screw rod 508 is located at one end of the sawtooth section 503 away from the fixing belt 505, the anti-slip block 509 is away from the other end of the fixing belt 505. By setting the anti-slip block 509, the adjusting belt 502 can be prevented from excessive movement and detachment from the screw rod 508.

[0025] A through hole is provided in the center of the support belt 506 for the screw 508 to pass through, and a bearing is embedded in the center of the connecting belt 507 for the screw 508 to be rotatably installed, so as to facilitate the rotation of the screw 508, so that the screw 508 drives the adjustment belt 502 to move through the engagement with the serrated segment 503, so as to adjust the tightness of the headband 1.

[0026] Connecting blocks 6 for installing one end of the fixing belt 505 and one end of the adjusting belt 502 are fixed inside the two ends of the headband 1 respectively. Protrusions are fixed to the inner walls at both ends of the headband 1. Springs 3 are connected between the protrusions and the earphone body 2. The resilience of the springs 3 enables the earphone body 2 to better fit the ears, thereby improving the wearing comfort of the earphone body 2.

[0027] A PCBA assembly for driving the earphone body 2 to make sound is installed inside the earphone body 2. Multiple sound holes 4 are set on the opposite side of the two earphone bodies 2. The PCBA assembly includes a PCB board, and parts such as a wireless transmitter, a speaker, and a microphone installed on the PCB board, which are used to enable the earphone body to make sound.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
