The embodiment of the invention provides a sound production device and a terminal. The sound production device comprises a shell and a sound production module arranged on the shell. The sound production module comprises a vibration assembly, a magnetic circuit assembly and a basin stand, and the basin stand is connected with the shell. The basin frame surrounds the peripheries of the vibration assembly and the magnetic circuit assembly, in the axial direction of the basin frame, the vibration assembly is at least partially located at one end of the basin frame, the magnetic circuit assembly is at least partially located at the other end of the basin frame, and one end of the vibration assembly surrounds one end of the magnetic circuit assembly. The elastic wave piece and the damping piece have different elastic coefficients, one end of the elastic wave piece is connected with the basin frame, and the other end of the elastic wave piece is connected with the vibration assembly. One end of the damping member is connected with the basin frame, and the other end is connected with the magnetic circuit assembly. The shell is simultaneously subjected to two elastic forces in opposite directions, and the two elastic forces can offset each other, so that the stress of the shell can be reduced, the vibration of the shell along with the sound production module can be reduced or avoided, the abnormal resonance sound generated by the vibration of the shell can be effectively avoided, and the sound quality of the sound production device can be effectively improved.
