A secondary part of an ironless linear motor includes a spacer and two yoke plates, which are arranged in parallel to each other and carry magnets having an alternating polarity. The yoke plates are maintained at a defined distance by the spacer. The spacer has at least two uninterrupted bore holes. Sleeves having a first screw head and an internal thread are inserted through one of the yoke plates and through a respective uninterrupted bore hole, the first screw heads securing the yoke plate in place on the spacer. A screw, having a second screw head, is screwed through the other yoke plate into each sleeve so that the second screw heads secure the other yoke plate in place on the spacer.

The actuator comprises a movable armature swivelling with respect to a stator provided with flanges on which magnets are fitted and a coil fitted around one of the flanges. The magnets have an axial magnetisation in a z axis and are aligned in an x axis. The movable armature is arranged between the magnets in the x axis. The movable armature is mounted on a guide imposing swivelling around a y axis perpendicular to the x and z axes. The movable armature is separated from the magnets by air-gaps. Each magnet forms a static magnetic circuit with one end of the movable armature and one of the flanges. The coil forms a dynamic magnetic circuit with the ends of the movable armature and the flanges.

The present invention provides a linear vibration motor, including a housing having an accommodating space, a vibrator disposed in the accommodating space, and a coil fixed in the housing and driving the vibrator to move. The vibrator includes a magnetic circuit system. The linear vibration motor further includes a restoring assembly fixed to the housing. The restoring assembly is made of magnetic steel and is magnetized along a direction perpendicular to a direction in which the vibrator moves. Compared with an existing spring structure, in the linear vibration motor of the present disclosure, a magnetic interaction force is formed between a restoring assembly and a vibrator to restore a vibrator. In this way, an anti-humidity and anti-high-temperature effect of the restoring assembly is improved by replacing an interaction force of a spring with a magnetic interaction force.
