Beschreibung
Zusammenfassung:	The invention relates to a device for producing sound and vibration (10) for a user to hear and feel via surface contact, which comprises a damper mass plate (15) and an inertial actuator (16) attached thereto, which inertial actuator (16) comprises a damper mass (14), which is via a primary suspension (11) supported in a springing manner on the inertial actuator (16) to be moving substantially in one linear direction, which inertial actuator comprises a power source for the damper mass (14). The device (10) comprises a secondary suspension (12) and a mechanical limiter (13) for improving the performance of the inertial actuator and/or protecting it from external disturbances.
