Abstract
A headphone device includes a first earmuff assembly, a second earmuff assembly, an arc-shaped connecting strip and a clamping force adjustment mechanism. The arc-shaped connecting strip is connected with the first earmuff assembly and the second earmuff assembly. The clamping force adjustment mechanism includes a first pressing plate, a second pressing plate, a slide block, a knob and a bolt. The arc-shaped connecting strip is clamped between the first pressing plate and the second pressing plate. The slide block is accommodated within an accommodation recess of the knob. The bolt is penetrated through the arc-shaped connecting strip and the second pressing plate and tightened into the slide block. While the slide block is driven by the knob and moved upwardly or downwardly along the bolt, a distance between the first pressing plate and the second pressing plate is changed, and the arc-shaped connecting strip is subjected to deformation.
