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.

A method of providing a mobile device with information of an incoming message using a tactile signal is provided. The method includes receiving the incoming message at the mobile device, determining at least one type of the tactile signal for the information of the incoming message based on a selected setting, transforming the information of the incoming message into the at least one type of the tactile signal, activating the at least one type of the tactile signal, and providing the mobile device with the information of the incoming message using the activated at least one type of the tactile signal.

An actuator includes a housing, a moving element and two springs connected between the housing and the moving element such that one of the two springs crosses the other of the two rotor springs without contacting the other of the two springs. A drive component causes the moving element to move.

An actuator device includes a support part, a first movable part, and a second movable part. The second movable part includes a pair of first connection portions positioned on both sides of the first movable part on a first axis and connected to a pair of first connecting parts, and a pair of second connection portions positioned on both sides of the first movable part on a second axis and connected to a pair of second connecting parts. An outer edge of each of the pair of the first connection portions includes a first linear portion that extends along a second axis direction. An outer edge of each of the pair of the second connection portions includes a second linear portion that extends along a first axis direction.

To prevent generation of a loud impact sound, a tactile generation apparatus is provided with a vibration generator on a back surface of a vibration member. The vibration generator is a solenoid including a movable core and a coil. The movable core is capable of moving close to and away from the vibration member. The coil displaces the movable core toward the vibration member to deform the vibration member when energized, and moves the movable core away from the vibration member when deenergized, so as to vibrate the vibration member due to an elastic restoring force of the vibration member.

This electromechanical transducer includes a pair of magnets, a pair of yokes that each comprise a plurality of yoke components superposed over each other in a flat-plate-form region and that guide magnetic fluxes generated by the magnets, a hollow-core coil to which an electric signal is supplied, an armature passed through a space inside a structural section formed by integrally arranging the magnets and the coil on the inner sides of the pair of yokes, and a pair of elastic members that each engage the structural section and the armature.

Provided is a vibration exciter, comprising a shell having a receiving space, a vibration unit suspended in the shell, a coil configured to drive the vibration unit, and an elastic member configured to suspend the vibration unit in the shell. The vibration unit comprises a mass block fixedly connected to the elastic member. The mass block comprises fixing planes opposite to each other along a vibration direction. The elastic member has one end fixed to the mass block and another end fixed to the shell, and a projection of the elastic member in the vibration direction is at least partially located in the fixing planes. Compared with the related art, the vibration exciter provided by the present invention can improve the vibration stability.

A linear actuator, comprising: a base; a fixed part support mechanism attached to the base; a fixed part elastically supported by the fixed part support mechanism; and a movable part driven to reciprocate in a predetermined drive direction with respect to the fixed part, wherein the fixed part support mechanism comprises: a movable block attached to the fixed part; a linear guide that couples the movable block with the base to be slidable in the predetermined drive direction; and an elastic member that is disposed between the base and the movable block and prevents transmission of a high frequency component of vibration in the predetermined drive direction.
