Abstract
The invention provides a sounding device. The sounding device comprises a housing body with an accommodating space, a one-way inlet valve and a one-way outlet valve. A speaker unit partitions the accommodating space into a front cavity and a back cavity. The one-way inlet valve communicates the outside and the back cavity and is used for introducing air into the back cavity. The one-way outlet valve communicates the back cavity and the outside and is used for discharging the air in the back cavity outside. A first through hole communicating the outside and the back cavity is formed in the housing body. The invention also provides a mobile terminal. Compared with the related art, the sounding device and the mobile terminal of the invention have better reliability and better performance.
