In the present embodiment, the overall height of the sidewall 111 of the magnetic carrier 11 is greater than or equal to the overall height of the first magnetic circuit module 13 and/or the second magnetic circuit module 14, but the present embodiment can be, but is not limited to, taking the overall height of the sidewall 111 greater than the overall height of the first magnetic circuit module 13 and/or the second magnetic circuit module 14 as an example; specifically, the two side walls 111 of the magnetic conductive carrier 11 are provided, one side surface of the bottom plate 112 has a first side 1121 and a second side 1122 opposite to the first side 1121, and the two side walls 111 are respectively disposed on the first side 1121 and the second side 1122 of the bottom plate 112.

The first voice coil 15 and the second voice coil 16 generate a magnetic field by the current. Thus, the magnitude and direction of the magnetic field generated by the first voice coil 15 and the second voice coil 16 can be changed by changing the magnitude of the current flowing into the first voice coil 15 and the second voice coil 16.
