Abstract
The invention relates to a sounding device having a first housing body with a first accommodation space, and a speaker box accommodated into the first housing body. The speaker box includes a second housing body with a second accommodation space, and a speaker unit accommodated in the second housing body. The speaker unit divides the second accommodation space into a front acoustic cavity. The sounding device further comprises a one-way intake valve. The speaker box, serving as a fan in a mobile terminal, pushes air circulation inside and outside the mobile terminal, thereby achieving a heat dissipation effect and facilitating internal cooling of the mobile terminal.
