があった。By the way, in the above-mentioned prior art, since the weight 21 is attached to the output shaft 20 of the motor, it is not only necessary to widen the interval so as not to contact other parts by rotation. However, in order to obtain a strong vibration, it is necessary to enlarge the weight 21, which is a serious obstacle for a hocket bell or the like that needs to be downsized.

The magnets 2 and 3 having the inner surface of the arc are fixed to the case 1 of the magnetic body so as to face each other to form a fixed body. Reference numeral 4 denotes a rotating body around which coils 5a, 5b and 5c are wound. Reference numeral 6 is a part of the outer circumference of the rotating body, and is configured to widen the gap 8 with the inner peripheral surfaces of the magnets 2 and 3. Among the three coils of the rotating body 4, the wire diameter of the coil 5c is made extremely smaller than the wire diameters of the other coils 5a and 5b to unbalance the rotation. Brushes 11a and 11b are electrically connected to the terminals 12a and 12b. 9 is a bearing, 13 is a terminal 12a,
It is a bracket of 12b.

気振動が発生する。Next, the operation will be described. Similar to the principle of the small DC motor, a DC voltage is applied to each of the terminals 12a and 12b, and a current flows from the brushes 11a and 11b and the commutator 10 to the coils 5a, 5b and 5c to rotate the rotor by the magnetic action of the magnets 2 and 3. Power is generated. When a current flows through the coil 5c, compared with the case where a current flows through the other coils 5a and 5b, the rotational force is extremely weakened and the coil 5c rotates, causing rotational magnetic vibration.
