The invention provides a sound production device which comprises a basin stand, a magnetic bowl contained in the basin stand, magnetic steel attached onto the magnetic bowl and a vibration diaphragm fixed on the basin stand. The magnetic bowl comprises a bottom wall. The magnetic steel comprises main magnetic steel attached to the bottom wall and auxiliary magnetic steel surrounding the main magnetic steel. The basin stand, the magnetic bowl and the vibration diaphragm together enclose an inner cavity. The basin stand further comprises a sound production portion arranged at one end on the basin stand far away from the vibration diaphragm, and the sound production portion is connected with the inner cavity. A plurality of notch portions are arranged on the auxiliary magnetic steel, at least one notch portion is directly connected with the sound production portion, and sound waves generated by vibration of the vibration diaphragm can be emitted out from the sound production portion through the notch portions. Compared with the prior art, the sound production device has good sensitivity and excellent acoustic performance.
