Abstract
The present disclosure provides a head-mounted device and relates to a field of smart device. The head-mounted device includes a first housing, two second housings and a tightness adjustment mechanism. The first housing defines a first receiving cavity and a second receiving cavity partitioned from each other along an up-down direction. The two second housings extend from either side of two opposite sides of the first housing respectively. Each of the two second housings defines a third receiving cavity. Each of the two third receiving cavities communicates with the first receiving cavity. A part of the first housing at a side of the second receiving cavity extends beyond the second housing. The tightness adjustment mechanism is received in the first receiving cavity. A motion of a pawl assembly is achieved, thus a tightness of the first and second head bands can be adjusted.
