    摘要： The present disclosure discloses a mobile terminal, including: a first terminal portion disposed with a first sound output hole; and a second terminal portion disposed with a second sound output hole and a receiver, where the second terminal portion can move between a first position and a second position relative to the first terminal portion. At the first position, the first sound output hole is connected to the second sound output hole, and at the second position, the second sound output hole is staggered from the first terminal portion. A baffle is disposed on the second terminal portion. The second terminal portion is located at the second position relative to the first terminal portion, and the baffle covers the second sound output hole. The second terminal portion is located at the first position relative to the first terminal portion, the baffle is removed away from the second sound output hole, and the first sound output hole is connected to the second sound output hole.
