AI Technical Summary
Technical Problem
Existing tactile presentation devices face a challenge in increasing the degree of freedom of force sense expression without significantly increasing the device size by using multiple actuators simultaneously.
Method used
An actuator design featuring a movable body with stacked magnets and yokes, supported by elastic elements, and housed within a fixed body with coils, allowing vertical vibration and simultaneous vibration outputs without requiring multiple actuators, thereby maintaining a compact size.
Benefits of technology
The actuator enhances force feedback expression by providing vibration output in multiple directions without enlarging the device, offering increased freedom in tactile sensation without increasing size.

Abstract
To provide an actuator that can increase the degree of freedom in force feedback expression without significantly increasing the size of the device. [Solution] The actuator's operating section comprises an upper shaft member and a lower shaft member, the base ends of which are attached to the upper and lower sides of the movable body, respectively, with their intermediate portions inserted into the upper and lower openings of the housing of the fixed body, and their respective tip portions protruding upward and downward from the housing; and an upper contact member and a lower contact member, respectively, provided at the tip ends of the upper shaft member and the lower shaft member so that an operator can contact them.
