Headset

摘要

A headset includes a housing having a first wall with at least one sound hole formed thereon, a loudspeaker unit disposed in the housing and adjacent to the sound hole, a blocking component mounted in the housing and capable of slidably moving towards and backwards the first wall to form an adjunctive chamber therebetween, and an adjustive component rotatably mounted to the housing. The adjustive component is connected with the blocking component in a way of screw link in order to drive the blocking component to move towards and backwards the first wall when the adjustive component is driven to rotate.
