In order to enable a user to intelligently adjust the length of the link structure according to the clamping force to the head when wearing the headset, and to improve the comfort of the user, as shown in fig. 1 to 7, the present invention relates to a headset 100 including a link structure 10, a main control chip (not shown), a pressure sensor 50 for detecting the pressure of the link structure 10 to the head, and headset shells 30 and 40 at both ends of the link structure 10; the connecting rod structure 10 comprises a connecting rod upper half shell 11 and a connecting rod lower half shell 12 which are buckled into a whole; the part of the connecting rod structure 10, which is close to at least one earphone ear shell, also comprises a support arm 13 positioned in a space surrounded by the upper half shell 11 of the connecting rod and the lower half shell 12 of the connecting rod, wherein a permanent magnet 131 is fixedly arranged on the support arm 13, and the lower end of the support arm is fixedly connected with the earphone ear shell; an upper electromagnet 122 and a lower electromagnet 123 positioned on two sides of the permanent magnet 131 are fixedly arranged on the inner wall of the lower half shell 13 of the connecting rod; the main control chip controls the distance between the upper electromagnet 122 and the permanent magnet 131 and the distance between the lower electromagnet 123 and the permanent magnet 131 according to the pressure value fed back by the pressure sensor 50, so that the support arm 13 moves together with the earphone ear shell.
Specifically, as shown in fig. 1, in the present embodiment, seven pressure sensors 50 are uniformly disposed on the outer wall of the lower half-shell 12 of the connecting rod, for detecting the pressure of the head of the user contacting the lower half-shell 12 of the connecting rod, wherein the pressure sensors located at the top of the head of the user play a main role in detection, and of course, other different numbers of pressure sensors 50 may be disposed for comprehensively detecting the pressure of the connecting rod structure 10 on the head of the user, and when the user wears the earphone 100, the pressure sensors 50 read the pressure value by squeezing, attaching, and the like. When the pressure value detected by one of the pressure sensors 50 is smaller than or larger than the preset threshold range, the expansion and contraction of the link structure 10 are adjusted until the pressure value is within the preset threshold range, in this embodiment, the preset threshold range can be written into the main control chip in advance by software or modified by software, the pressure sensor 50 transmits the pressure value detected in real time to the main control chip, and the main control chip outputs a control signal after calculation and analysis, thereby controlling the expansion and contraction of the link structure 10. When the pressure value detected by the pressure sensor 50 is smaller than a preset threshold range, the main control chip controls the upper electromagnet 122 to attract the permanent magnet 131 and the lower electromagnet 123 to repel the permanent magnet 131, so that the support arm 13 and the earphone earshells move upwards, and when the pressure value is larger than the preset threshold range, the main control chip controls the upper electromagnet 122 to repel the permanent magnet 131 and the lower electromagnet 123 to attract the permanent magnet 131, so that the support arm 13 and the earphone earshells move downwards.
In this embodiment, in order to facilitate rapid adjustment of the length of the link structure 10, the structure in a portion of the link structure 10 near the left earphone ear shell 30 is the same as the structure in a portion near the right earphone ear shell 40, and the control thereof by the main control chip is also the same, as shown in fig. 2.
