DUAL DIRECTION MAGNET ACTUATOR

A magnet actuator (1) comprising a first housing arrangement (2) comprising a first housing (2a), a first balancing magnet (2b), and a first coil (2c) partially surrounding the first balancing magnet (2b), a second housing arrangement (3) comprising a second housing (3a), a second balancing magnet (3b), and a second coil (3c) partially surrounding the second balancing magnet (3b), and a main magnet (4) arranged between the first balancing magnet (2b) and the second balancing magnet (3b). A first constant attractive force (FC1) is generated between the first housing (2a) and the main magnet (4), the first balancing magnet (2b) and the main magnet (4) being configured to generate a first constant repulsive force (FC2) counteracting the first constant attractive force (FC1), such that the first housing arrangement (2) and the main magnet (4) are maintained in a force equilibrium state. A second constant attractive force (FC3) is generated between the second housing (3a) and the main magnet (4), the second balancing magnet (3b) and the main magnet (4) being configured to generate a second constant repulsive force (FC4) counteracting the second constant attractive force (FC3), such that the second housing arrangement (3) and the main magnet (4) are maintained in a force equilibrium state. The first coil (2c) and the main magnet (4) are configured to generate a first alternating magnetic force (FA1), and the second coil (3c) and the main magnet (4) are configured to generate a second alternating magnetic force (FA2). Manipulating electrical current in the first coil (2c) causes a change in the first alternating magnetic force (FA1) thereby causing displacement of the first housing arrangement (2) in relation to the main magnet (4), and/or manipulating electrical current in the second coil (3c) causes a change in the second alternating magnetic force (FA2) thereby causing displacement of the second housing arrangement (3) in relation to the main magnet (4). By using one magnet to operate two moving magnets, the magnet actuator is made compact while being able to generate resonance frequencies within two different ranges simultaneously.
