摘要： The present invention discloses a counterweighted vibration device and a manufacturing method thereof. The counterweighted vibration device includes a shell provided with a hollow cavity and a vibration assembly, wherein the shell is provided with two elastic support structures located at two ends of the vibration assembly, and the shell is further provided with slots configured for passage of the two ends of the vibration assembly and to be in communication with the hollow cavity; the vibration assembly includes two counterweights each located at one of the two ends thereof, short strong magnetic strips each adjacent to one of the counterweights, a long strong magnetic strip located between the two short strong magnetic strips, and two fixing screws located on two sides separately and configured to couple the counterweights, the short strong magnetic strips and the long strong magnetic strip together; the vibration device further includes two coils, and a change in a current flowing through each of the two coils causes a magnetic force to change, so as to produce vibration of the vibration assembly in proportion to the change in the current; and the counterweights are of a non-magnetic material. In the present invention, a magnetic field generated by the short strong magnetic strips and the long strong magnetic strip is limited to a smaller range, so that the movement range of the magnetic field of the vibration assembly during vibration is reduced, thereby reducing the influence on the coils and providing a better vibration effect.

摘要： An ultrasound probe includes: a metal case including a bottom wall portion having a vibration surface, and a side wall portion connected to the bottom wall portion; a coil mounted on one surface of the side wall portion; and a magnet mounted in such a way as to sandwich the coil between the magnet and the one surface of the side wall portion, in which the coil causes an eddy current to occur in the one surface of the side wall portion, and causes the bottom wall portion to vibrate, by using a Lorentz force occurring in the side wall portion because of the interaction between the eddy current and a magnetic field generated by the magnet.

摘要： Embodiments described herein relate to methods and apparatuses for controlling an operation of a vibrational output system and/or an operation of an input sensor system, wherein the controller is for use in a device comprising the vibrational output system and the input sensor system. A controller comprises an input configured to receive an indication of activation or de-activation of an output of the vibrational output system; and an adjustment module configured to adjust the operation of the vibrational output system and/or the operation of the input sensor system based on the indication to reduce an interference expected to be caused by the output of the vibrational output system on the input sensory system.

摘要： A vibration actuator includes: a fixing body including a hollow case and a coil, a movable body that includes a magnet, and an elastic supporting part that supports the movable body such that the movable body is freely movable with respect to the fixing body in the hollow case. The hollow case restricts a movement range of the movable body in the case by opposite end surface portions that are disposed to face each other at a distance from each other in the vibration direction of the movable body, the hollow case includes one or more vent holes, and the vent holes are disposed in a portion of at least one end surface portion of the opposite end surface portions, the portion being free from interference by the movable body.

摘要： This specification describes a transducer configured to convert electrical signals into vibrational movement. The transducer comprises an axially-magnetised reciprocating magnet magnetically suspended between first and second axially-magnetised stationary magnets located on opposing sides of the axially-magnetised reciprocating magnet, wherein the axially-magnetised reciprocating magnet comprises an aperture such that the reciprocating magnet has an inner boundary and an outer boundary. The transducer further comprises at least two pairs of concentrically positioned electromagnetic solenoids, the at least two pairs of concentrically positioned electromagnetic solenoids being configured to drive the reciprocating magnet to reciprocate in a volume between the first and second axially-magnetised stationary magnets. The first solenoid of each of the pairs of concentrically positioned electromagnetic solenoids is positioned to influence the reciprocating magnet at the inner boundary more than at the outer boundary, and a second solenoid of each of the pairs of concentrically positioned electromagnetic solenoids is positioned to influence the reciprocating magnet at the outer boundary more than at the inner boundary.

摘要： A vibrator-mounted holder is attached to a casing of a vibration generator which moves a vibrator to generate a vibration when used. The vibrator-mounted holder includes a vibrator, a vibrator retention unit retaining the vibrator, a fixing unit fixed to a casing, and an arm. The vibrator includes a magnet having a plate shape parallel to a horizontal surface and a yoke arranged on the magnet. The arm connects the fixing unit to the vibrator retention unit, and supports the vibrator retention unit in a manner that the vibrator retention unit is displaceable with respect to the fixing unit. The yoke has a projecting portion which is projected downward and fixed to the vibrator retention unit. The arm is connected to a portion, at which the projecting portion is arranged, within the vibrator retention units.

摘要： In one embodiment of the present disclosure a haptic actuator is disclosed. The haptic actuator includes a housing, a movable mass, and a pivot assembly attaching the movable mass to the housing. The pivot assembly defines a pivot axis, and the movable mass has a mass center offset from the pivot axis along a lever arm extending perpendicular to the pivot axis. The haptic actuator includes a spring extending between the movable mass and the housing. The spring stores and releases energy received from movement of the movable mass. The spring prevents full rotation of the movable mass about the pivot axis. The haptic actuator includes an electric coil attached to the movable mass. The electric coil intersects the lever arm. The haptic actuator includes at least one magnet attached to the housing. The magnet is at least partially aligned with the electric coil. The movable mass moves with respect to the at least one magnet when a signal is applied to the coil.
