Abstract
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.
Claims6
A device for producing sound and vibration for a user to hear and feel via a surface contact, the device comprising:
- a damper mass plate and an inertial actuator attached thereto,
- the inertial actuator comprising a damper mass and a power source for the damper mass,
- the damper mass being supported via a primary suspension in a springing manner on the inertial actuator to be moving in one linear direction,
- wherein the device further comprises a secondary suspension and a mechanical limiter in order to improve the performance of the inertial actuator and/or protect it from external disturbances, and
- a mechanically dampened resonator arranged to protect the inertial actuator from hits and/or pressure load directed onto it, which mechanical dampened resonator is equipped with a divided reaction mass designed in an advantageous manner.
