1. An actuator for exciting at least one component of a motor vehicle with vibrations, the actuator comprising:
a housing which is configured to be connected to the component;
an electrical coil which is rigidly connected to the housing and is configured to generate a magnetic field when an electrical current flows through the coil; and
a magnet which is arranged in the housing so as to be movable to a limited extent,
wherein the coil has a fixed connection to the housing by an adhesive connection of thermally relatively highly conductive adhesive, wherein said adhesive has a thermal conductivity of at least 0.8 W/(m K).
 
13. An actuator for exciting at least one component of a motor vehicle with vibrations, the actuator comprising:
a housing which is configured to be connected to the component;
an electrical coil which is rigidly connected to the housing and is configured to generate a magnetic field when an electrical current flows through the coil;
a magnet which is arranged in the housing so as to be movable to a limited extent; and
a spring arrangement which is configured to bias the magnet into an inoperative position, wherein the spring arrangement is configured to bias the magnet in a manner returning same back to the inoperative position along every possible direction of movement.
