Abstract
The present disclosure provides a speaker box. The speaker box includes an upper housing, a lower housing forming an accommodating space together with the upper housing, and a speaker unit accommodated in the accommodating space. The speaker unit includes a diaphragm configured to vibrate and produce sound. The diaphragm is disposed separately from the upper housing to define a front acoustic cavity. The speaker box further includes a sound channel communicating the front acoustic cavity with an external environment. The front acoustic cavity and the sound channel constitute a front cavity of the speaker box together. A baffle fixedly connected to the upper housing is disposed in the sound channel. The baffle and the upper housing define a resonant cavity in communication with the front acoustic cavity, and the resonant cavity has an inlet facing to the front acoustic cavity.
