Problems solved by technology

[0004] It is known from the prior art that in inertial actuators based on moving damping masses, the suspension assembly that makes possible the linear movement supported by one or more damping springs may pose limitations at low frequencies because the suspension is rigid , and the deviation of the moving damping mass is limited
In addition, encapsulated protective structures, especially those employing lightweight construction, may induce problematic resonant frequencies in the structure at high frequencies
A factor causing problematic situations in inertial actuators based on moving damping masses is the mechanical durability of the actuator, e.g. in case of transport and / or falling, whereby the damping mass may become detached from the suspension structure
Additionally, a damping mass intended to move in the normal direction in a linear fashion can end up with a lateral or rotational motion, which causes disturbances in sound and vibration, and can cause wear at certain natural frequencies

Description

technical field [0001] The present invention relates to a device for generating sound and vibrations to be heard and felt by a user via surface contact. More specifically, the present invention relates to an apparatus for producing sound and vibrations to be heard by a user and felt via surface contact, said apparatus comprising a damping mass plate and an inertial actuator attached to said damping mass plate The inertial actuator includes a damping mass elastically supported on the inertial actuator via a main suspension so that the damping mass moves in one linear direction, the An inertial actuator comprises a power source for the damping mass. Background technique [0002] It is known from the prior art that the perception of sound is based not only on hearing but also on touch. The sense of touch is primarily an unconscious sense that works behind the scenes to provide important information about the state of the body (such as pain perception) and to control motor fun...
