Description
ここで、本実施の形態では、マグネット６０は、コイル４０に対向する底面側部分がＮ極又はＳ極の一極になるように着磁されている。そのため、４つのコイル４０のそれぞれに、次のような態様で交流電流を印加することで、振動子８０を、フレーム２０に対して、Ｘ軸方向（第１の運動方向）、Ｙ軸方向（第３の運動方向）、Ｚ軸方向（第２の運動方向）など、所定の方向に往復運動させることができる。 Here, in the present embodiment, the magnet 60 is magnetized so that the bottom side portion facing the coil 40 becomes one pole of the N pole or the S pole. Therefore, by applying an alternating current to each of the four coils 40 in the following manner, the vibrator 80 is moved with respect to the frame 20 in the X-axis direction (first movement direction) and the Y-axis direction ( (Third movement direction) , Z-axis direction (second movement direction), etc., and can be reciprocated in a predetermined direction.
ここで、第２の実施の形態においては、コイル１４０ａは、振動発生器１の左後方に配置されている。コイル１４０ｂは、平面視で、振動発生器１の右後方に配置されている。コイル１４０ｃは、平面視で、振動発生器１の右前方に配置されている。コイル１４０ｄは、平面視で、振動発生器１の左前方に配置されている。すなわち、平面視で、振動子８０の第１の運動方向（左右方向）から水平面に垂直な軸周りに４５度回転した方向に対応する位置に２つのコイル１４０ｂ，１４０ｄが配置され、振動子８０の第３の運動方向（前後方向）から水平面に垂直な軸周りに４５度回転した方向に対応する位置に他の２つのコイル１４０ａ，１４０ｃが配置されている。各コイル１４０は、その三角形形状のうち１つの頂点部分が前後左右の中央部に向くようにして、配置されている。 Here, in the second embodiment, the coil 140 a is disposed on the left rear side of the vibration generator 1. The coil 140b is disposed on the right rear side of the vibration generator 1 in plan view. The coil 140c is disposed on the right front side of the vibration generator 1 in plan view. The coil 140d is disposed on the left front side of the vibration generator 1 in plan view. That is, the two coils 140b and 140d are arranged at a position corresponding to a direction rotated 45 degrees around an axis perpendicular to the horizontal plane from the first movement direction (left-right direction) of the vibrator 80 in plan view. The other two coils 140a and 140c are arranged at positions corresponding to a direction rotated 45 degrees around an axis perpendicular to the horizontal plane from the third movement direction ( front-rear direction). Each coil 140 is arranged so that one apex portion of the triangular shape faces the center portion of the front, rear, left and right.
