Beschreibung
Zusammenfassung:	A magnet actuator (1) for use in an electronic device (2) comprising a coil (3), a magnet (4), a first housing (5), and a second housing (6), the coil (3) being at least partially located within, andfixed to, the first housing (5), the magnet (4) being at least partially located within, and fixed to, the second housing (6). The first housing (5) comprises a magnetic material, and a magnetic field, generated by the magnet (4) and the first housing (5) causes an attractive force (F) between the magnet (4) and the first housing (5), the magnet (4) and the first housing (5) being in a force equilibrium state, wherein an air gap (7) is provided between the magnet (4) and the coil (3). Manipulating electrical current in the coil (3) causes a change in the attractive force (F), thereby causing adisplacement between the magnet (4) and the first housing (5), allowing vibrations to be generated within the electronic device (2). 一种用于电子设备(2)的磁铁激励器(1)包括：线圈(3)、磁铁(4)、第一外壳(5)以及第二外壳(6)，其中，所述线圈(3)至少部分位于所述第一外壳(5)内并固定至所述第一外壳(5)上
