Abstract
The present application provides a sounding device. The sounding device includes a front surface with a sound outlet hole; a back surface; a sounding component and an outer casing. The outer casing is covered outside the sounding component. A cavity is formed between the outer casing and the end of the sounding component close to the back side. A sound guiding channel is arranged in the outer casing. One end of the sound guiding channel is communicated with the sound outlet hole, and the other end of the sound guiding channel is communicated with the cavity. The sounding device of the present application provides a smooth transmission channel for the sound from the back side by arranging the sound guiding channel in the outer casing, thereby strengthening the frontal sound of the sounding device and greatly improving the loudness of the sounding device.
