An actuator, including an electric drive for converting electrical signals into mechanical forces and/or deflections. The drive having at least one coil through which the current of the electrical signal can flow and having at least two magnets which can electromagnetically interact with the coil. The actuator being designed to excite a body which can be connected to the actuator, in particular a flat body, to vibrate, as a result of which the body can emit acoustic sound. The two magnets are arranged such that they form a substantially straight air gap between them, the coil being arranged in the air gap.

Electrodynamic vibration exciter

An actuator for exciting at least one component of a motor vehicle with vibrations. The actuator includes: a housing which is configured to be directly or indirectly connected to the component, an electrical coil which is connected to the housing and is configured to generate an electromagnetic field when an electric current flows through the coil, and a magnet which is entirely or partially arranged in the housing and the magnet is arranged so as to be movable to a limited extent relative to the housing. The housing has, all around, at least one electrically conductive ring which surrounds the magnet in respect of its undeflected state.

Actuator for exciting vibration having at least one electrically conductive ring

An actuator for exciting a component of a motor vehicle with vibrations. The actuator has a housing, an electrical coil and a magnet that is movable to a limited extent in the housing.

Vibration actuator for rigid structures for high-performance bass playback in automobiles

A sound emission arrangement, having a seat that has a backrest surface and a headrest surface, where the sound emission arrangement has at least one first and one second actuator for vibration excitation, where each of the two actuators is arranged in the seat, so that the first and the second actuator are each arranged with their excitation surface on the inner side of a covering of the headrest surface or the inner side of a covering of the backrest surface at substantially the same height.

Seating means with actuators for sound emission

An actuator, including an electric drive for converting electrical signals into mechanical deflections, the drive having a coil through which the current of the electrical signal can flow, and having a permanent magnet which can be in electromagnetic interaction with the coil, the actuator furthermore has a housing and a flat body, the flat body being able to be mechanically deflected and/or mechanically excited into vibration by the electric drive and, in the process, being able to radiate acoustic sound signals, wherein the flat body is connected integrally to at least part of the housing and at least part of the drive is connected to the flat body.

Actuator for generating structure-borne sound

A sound speaker for a vehicle is provided. The sound speaker includes a flat surface with a rod extending perpendicular from the surface, a cylindrical electro-dynamic exciter with an axial longitudinal through hole arranged for receiving the rod and a circular clamp for securing the electro-dynamic exciter on the first flat surface in a closed position. The electro-dynamic exciter includes a longitudinal rib inside the through hole and the rod includes a longitudinal recess for receiving the rib. The rod further includes a lateral recess for receiving the clamp. A least a part of the lateral recess forms a conical frustum and the clamp in the closed position forms a corresponding conical frustum. This part of the lateral recess pushes the clamp in the closed position against the electro-dynamic exciter towards the flat surface.
