It should be noted that, the first direction defined herein is an X-axis direction or a Y-axis direction of three mutually perpendicular X-axis, Y-axis and Z-axis directions in the space rectangular coordinate system, and the second direction is a Z-axis direction, specifically, in this embodiment, the first direction is an X-axis direction.
Wherein, as shown in fig. 1 and 2 together, the housing comprises a first housing 1 and a second housing 2 which are mutually matched to form a containing cavity. The first housing 1 here may be an upper or lower housing of a so-called linear vibration motor, and the second housing 2 may be a lower or upper housing of a so-called linear vibration motor, respectively.

The linear vibration motor in this embodiment can realize the following two modes of motion by the different directions of the input currents: in the first movement mode, as shown in fig. 3, when the first coil 71 and the second coil 72 are energized with a reverse ac current, the counter force of the driving forces applied to the two coils in the magnetic field drives the weight 3 of the linear vibration motor to move in a first direction, namely, in the so-called X-axis direction; in the second movement mode, as shown in fig. 4, when the first coil 71 and the second coil 72 are energized with an ac current in the same direction, the counter force of the driving forces applied to the two coils in the magnetic field drives the weight 3 of the linear vibration motor to vibrate in a second direction, that is, in the so-called Z-axis direction.
