Abstract
A headband adjustment structure includes a rotary adjusting assembly, a wearing unit having an adjustable accommodation space, a cable management module located between the wearing unit and the rotary adjusting assembly for carrying a cable, an adjustment gear set linkably coupled to the cable management module, and a driving rotation shaft set passing through the wearing unit and the cable management module, and linkably coupled to the wearing unit and the adjustment gear set, and coaxially connected to the rotary adjusting assembly. When the rotary adjusting assembly rotates the driving rotation shaft set, the driving rotation shaft set synchronously moves the wearing unit to adjust the adjustable accommodation space, and moves the cable management module through the adjustment gear set. The amount of the movement of the cable management module is different from that of the wearing unit.
