PROBLEM TO BE SOLVED: To provide an actuator, touch panel display device and electronic apparatus advantageous for ensuring the magnitude of vibration to generate while attaining miniaturization. SOLUTION: The actuator 10 includes a diaphragm 12, a housing 14, a coil 16, a magnet 18, a yoke 19, a spring 20, a cover 21, and a weight increasing part W. A weight increasing member WM is housed and fixed in a through hole 180 of the magnet 18. When a predetermined electric signal (current signal) is supplied from an external device to a lead part 16B of the coil 16, both the coil 16 and a movable body 25 are relatively moved in an axial center direction by magnetic inter-operation of a magnetic field of the coil 16 and a magnetic field of the magnet 18. Thus, the diaphragm 12 vibrates in a thickness direction to generate sound. At the same time, the movable body 25 vibrates in the axial center direction and the vibration is transported to the housing 14 to vibrate the housing 14. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a protector for an optical element capable of moving a barrier blade in the closing direction of an aperture during non-energization, thereby preventing the aperture from being kept open caused by vibration, external force, or the like. SOLUTION: The protector is provided with: a stator section 58 incorporating a coil and a magnetic core; a drive section 19 having a rotor part 66 incorporating a magnet 67; and a movable blade 20 moved in the direction where the aperture 15 is closed or opened. When energizing the coil, the drive section moves the movable blade 20 to a first position that the aperture is closed by the movable blade and to a second position that the movable blade is moved farther in the direction than the position where the aperture is fully opened. During the non-energization, the movable blade is moved in the closing direction by the holding torque of the drive section 19, and the range of rotation in the closing direction is made greater than the range of rotation in the opening direction with the rotated position of the rotor part 66 when the holding torque is the smallest as a reference, and also the aperture is fully opened in a third position, which is between the first and second positions and in the closing direction rather than in the position of the reference.
