A soil processing roller for a soil processing machine includes a roller shell elongated in the direction of a roller axis of rotation and surrounding a roller interior and an unbalanced arrangement arranged at least partially in the roller interior. The unbalanced arrangement includes at least one unbalanced mass rotatable around an unbalanced axis of rotation having center of mass eccentric to the unbalanced axis of rotation and an unbalanced drive system having at least one unbalanced electric drive motor for driving the at least one unbalanced mass to rotate around the unbalanced axis of rotation. The at least one unbalanced mass is in an idle position when the unbalanced arrangement is deactivated, and the unbalanced drive system is designed, upon deactivation of the unbalanced arrangement, to operate the at least one unbalanced electric drive motor in an unbalanced return phase such that the at least one unbalanced mass is moved into the idle position.

A wheel assembly for a shaft of a screening machine includes a disc and a first and a second weight unit. The first and the second weight units are arranged such that the disc is in equilibrium along a longitudinal axis passing through the center of the disc and the longitudinal axis is perpendicular to a diametrical extension of the disc. A screening machine having the wheel assembly is also provided.

A game controller including a housing with a first handgrip and a second handgrip is provided. The game controller includes a first vibration actuator integrated within the housing proximate to the first handgrip. Further included is a second vibration actuator integrated within the housing proximate to the second handgrip. A controller device is included and is configured to communicate one or more vibrational signals to one or both of the first vibration actuator and the second vibration actuator. The vibrational signals are configured to cause the housing of the game controller to vibrate in a vibrational pattern during use of the controller. The vibrational pattern is one of a plurality of vibrational patterns, and one or more of the plurality of vibration patterns are activated in correlation to one or more game actions occurring during gameplay of a video game using the game controller.

The invention relates to a machine for stabilising a track, having a machine frame supported on rail-based running gears and at least one height-adjustable stabilising unit which can be rolled on rails of the track by means of work unit rollers, comprising a vibration exciter with rotating unbalanced masses for generating an impact force acting dynamically in a track plane normal to a longitudinal direction of the track as well as a linear drive for generating a load acting on the track. It is provided that a main unbalanced mass and a secondary unbalanced mass produce different centrifugal forces at the same rotational speed depending on the direction of rotation, the two unbalanced masses being coupled in such a way that, during rotation in one direction of rotation, the unbalanced masses have a first phase shift in relation to one another and that, during rotation in the opposite direction of rotation, the unbalanced masses have a second phase shift relative to one another which differs from the first phase shift. Depending on the arrangement of the unbalanced masses, a changed phase shift changes both the direction and the strength of the impact force.

A vibration generating mechanism for a screen box includes a drive shaft arranged to be rotatably driven by a drive motor, at least one first eccentric out-of-balance weight fixed with respect to the drive shaft for rotation therewith and at least one second eccentric out-of-balance weight coupled to the drive shaft via gearing. The first and second out-of-balance weights rotate in opposite directions when driven by the drive shaft.

Provided is a vibration device using sound and a system comprising the same. More particularly, the present invention relates to a vibration device for generating vibration using sound such that the beat of the sound can be felt, which is convenient to carry or transfer due to a lightweight and compact size thereof, is capable of generating vibration matching the beat of sound to which a user is currently listening, is furthermore capable of generating vibrations of various feelings matching the beat of sound according to user settings, thereby greatly enhancing effects that the user may feel, and is very inexpensive to manufacture, and a system comprising the vibration device.

A strut mount including: a first mounting member configured to be attached to a shock absorber; a second mounting member configured to be attached to a vehicle body; a main rubber elastic body elastically connecting the first and second mounting members to each other; a fluid-filled zone whose interior is filled with a non-compressible fluid such that a vibration damping effect is obtained based on a flow action of the fluid; and an orifice passage through which the fluid filled in the fluid-filled zone is induced to flow. A tuning frequency of the orifice passage is set to a frequency of a vibration transmitted during lockup of an automobile from a drive train of the automobile to the vehicle body via the shock absorber.

The present invention discloses electronic equipment with a vibration function, including a carrier and a vibration module configured for providing a vibration sense; the vibration module includes a housing having a receiving space and provided with an opening in at least one end; a vibration unit received in the receiving space and directly providing a vibration sense to a user; and an elastic member; the elastic member elastically connects the vibration unit to the housing, so as to elastically suspend the vibration unit in the receiving space. According to the electronic equipment of the present invention, in both cases where a surface of the carrier is a flexible material and the carrier is relatively heavy, local vibration can be provided through the independent vibration unit, so as to directly feedback vibration actually generated by the vibration unit to the user, thus improving the experience of the user.
