In the process of improving the user's audio experience and vibration tactile experience, the loudspeaker device and the motor device are provided separately in the relevant technology, resulting in problems such as large space occupation in smart terminal devices, unsatisfactory layout effect, etc., thereby affecting the user experience of the smart terminals.

Meanwhile, the coil 21 of the vibration module 2 is disposed in the mounting cavity 11, and the vibrator assembly 22 is suspended in the mounting cavity 11 and is opposite the coil 21, so that the coil 21 can be used to drive the vibrator assembly 22 to vibrate in the mounting cavity 11 to realize the function of motor vibration, and as a result, the sound production device 100 has a vibration tactile experience function. Further, the magnetic circuit system 32 of the loudspeaker module 3 is disposed on the side of the vibrator assembly 22 facing away from the coil 21 and is opposite the vibration system 31, so that on the one hand, the sound production function of the loudspeaker module 3 is realized by the cooperation of the vibration system 31 and the magnetic circuit system 32, and on the other hand, the coil 21 is used to drive the vibrator assembly 22 to drive the magnetic circuit system 32 to vibrate synchronously, and thus, the vibration module 2 and the loudspeaker module 3 of the sound production device 100 can work separately without interfering with each other, and as a result, the sound production device 100 has both audio experience and vibration tactile experience functions, thereby improving the user experience.

In the embodiment, as shown in
It will be understood that in the vibration system 31, the voice coil 312 drives the diaphragm assembly 311 to vibrate in a vertical direction, while the coil 21 of the vibration module 2 drives the magnet assembly 2214 to drive the counterweight base 2212 and the magnetic circuit system 32 to vibrate and move in the horizontal direction, so that the vibration module 2 and the loudspeaker module 3 in the sound production device 100 can work separately without interfering with each other.
It should be noted that the side magnetic circuit part 322 may be an integral annular structure, and the central magnetic circuit part 321 is an annular inner portion of the side magnetic circuit part 322 and is spaced from the side magnetic circuit part 322 to form a magnetic gap 323. Of course, in other embodiments, the side magnetic circuit part 322 may be a plurality of split structural components, and the plurality of split structural components are arranged at intervals around the central magnetic circuit part 321, but it is not limited thereto.
