  • Patent number: 12225366
    Abstract: Acoustic transducer comprises an upper part (301) and a lower part (302), with a first permanent magnet (303) in the upper part (301) and a second permanent magnet (304) in the lower part (302). Similarly named magnetic poles of the first and second permanent magnets (303, 304) face each other. An upper cover (306) in the upper part (301) and a lower cover (307) in the lower part (302) comprise magnetic material and define an enclosure around the magnets (303, 304). A coil (308) creates, under influence of an electric current, dynamic magnetic forces. A separating gap (309) between edges of said upper cover (306) and lower cover (307) is directed so that it allows a relative movement of the edges of said lower cover (307) and said upper cover (306) between different positions, said positions differing in the extent to which edges coincide.

  • Patent number: 11388521
    Abstract: An arrangement for generating vibration according to an electrical input signal includes a first permanent magnet arrangement including a first permanent magnet, a frame including magnetic material, a second permanent magnet configured to be arranged between the first permanent magnet and the frame and to be coupled with the frame, one or more portion of the frame extending at least in one direction over an edge area of the second permanent magnet. The second permanent magnet is further configured to face, at a distance, the first permanent magnet such that a magnetic interaction between the first permanent magnet and the second permanent magnet causes a first force to a surface of an apparatus, wherein the frame is configured to be magnetized by the second permanent magnet in order to cause magnetic interaction between the one or more portion of the frame and the first permanent magnet arrangement in order to cause a second force to the surface having an opposite direction compared with the first force.

  • Patent number: 11234080
    Abstract: An apparatus includes a surface arranged to be mechanically displaced, a first magnet coupled with the surface, at least one supporting member for supporting the surface, a base comprising a second magnet, wherein the second magnet is arranged, at least partially, to face the first magnet, a coil coupled with the second magnet, and a signal port electrically coupled with the coil. An electrical signal is configured to travel between the signal port and the coil, and the electrical signal in the coil is proportional to mechanic displacement of the surface when a force equilibrium state of the surface is broken either by the electrical signal in the coil or the mechanic displacement of the surface from a position of the force equilibrium state.
