いると、上述した支持杆が不要になる。According to the vibration generator of the present invention, when the polarity of the yoke portion of the electromagnetic drive section is switched at high speed, an attracting action and a repulsive action occur between the magnetizing member and the yoke portion. Due to the influence, the magnetized member reciprocates while floating in the space formed by the yoke portion. Vibration is generated due to the high-speed change of the position of the center of gravity accompanying the reciprocating movement of the magnetized member. Nevertheless, since there is no sliding part or rotating part in the magnetized member or the electromagnetic drive part, no sound is generated due to sliding or rotating. In particular, in the vibration oscillating device configured as described in claim 2, although the size of the permanent magnet can be reduced, it is possible to reduce the size of the permanent magnet of the metallic member having magnetic susceptibility arranged on both sides of the permanent magnet. The magnetic efficiency can be increased by the action, and the vibrating device configured as described in claim 3 has a simplified structure for supporting the magnetized member in a floating state. In addition, claim 4 and claim 5
In the vibration oscillating device configured as described in (1), since the magnetizing member is supported by the supporting rod made of the leaf spring material, it is not always necessary to keep the magnetizing member horizontal by appropriately setting the spring force of the supporting rod. There is no need to move back and forth. That is, even if the reciprocating direction of the magnetizing member is vertical, for example, if the magnetizing member is held in the middle part of its reciprocating path by the spring force of the support rod, The magnetizing member reciprocates under the influence of the attracting action and the repulsive action that occur with the yoke portion, and the vibration occurs due to the accompanying change in the center of gravity position at high speed. If the vibrating device according to the present invention is configured as described in claim 6, the support rod described above is not necessary.

２で説明したものと同等の作用が奏される。1 is a plan view of a vibrating device according to an embodiment of the present invention according to claim 1, claim 2, claim 3 and claim 4,
FIG. 2 is a sectional view taken along the line II-II in FIG. In this vibration oscillating device, the electromagnetic drive unit 1 includes a coil portion 2 formed by winding a wire rod 22 made of a conductor around a bobbin 21 made of synthetic resin, and a central hole 23 of the bobbin 21 of the coil portion 2. The iron core 3 that is inserted and surrounded by the coil portion 2 and the disk portion 41 are crimped and coupled to the iron core 3, and the cylindrical body 42 may surround the coil portion 2. Thus, the yoke portion 4 made of a metal material having magnetic susceptibility, such as iron, is integrally provided upright from the outer peripheral portion of the disc portion 41. In the electromagnetic drive unit 1, when the power source is connected to the wire 22 of the coil unit 2, the two polarities of the body 42 of the yoke 4 separated by 180 degrees are magnetized to the same polarity. When an AC power source is selected as the power source, 180 degrees of the body portion 42 of the yoke portion 4 is selected.
The polarities at two places separated by degrees are switched to N pole and S pole alternately at high speed. In addition, depending on the type of power source connected to the wire rod 22 of the coil portion 2, 18 of the body portion 42 of the yoke portion 4 may be used.
N (S) pole-non-polarity-N (S)
It is also possible to alternately switch between a magnetized state and a non-magnetized state such as pole-polarity. A magnetized member 6 is provided in a space 5 of the yoke portion 4 surrounded by the body portion 42.
The magnetizing member 6 is composed of a permanent magnet 61 and metal members (magnetic bodies) 62 and 63 having magnetism such as iron provided on both surfaces of the permanent magnet 61, and has a rectangular shape in a plan view. The body portion 42 of the yoke portion 4 is formed with recessed portions 43 and 44 at two positions 180 degrees apart from each other in the axial direction. Each of the recessed portions 43 and 44 is made of a leaf spring material. The circular curl portions 73 and 74 provided at the base end portions of the pair of support rods 71 and 72 are held. In addition, the tip ends of the support rods 71 and 72 respectively have a pair of attachment piece portions 75 and 7 that are bent in opposite directions.
5, 76, 76 are provided, and these mounting piece parts 7
5, 75, 76, and 76 are separately fixed to both side surfaces of the magnetizing member 6. That is, the magnetized member 6 is held between the tip portions of the pair of support rods 71 and 72. Here, the pair of support rods 71, 72 made of a leaf spring material have their width directions aligned with the axial direction of the iron core 3, and the recessed portions 43, 44 include the curl portions 73, 74 in the body portion 42. It is held so as to be movable in the perspective direction with respect to the axis center of, that is, in the withdrawal direction (indicated by arrows A and B). The magnetizing member 6 is attached to the iron core 3 by the supporting rods 71 and 72.
In the state in which the support rods 71 and 72 are supported with a slight gap 8 between them and no external force is applied to the support rods 71 and 72, as shown in FIG.
-L passes through the center of the magnetized member 6. With this configuration, the magnetized member 6 can reciprocate along the linear path against the spring force of the support rods 71 and 72 in a floating state in the space 5 formed by the yoke portion 4. Therefore, the support rods 71 and 72 extend from the body portion 42 of the yoke portion 4 in a direction intersecting with the reciprocating direction of the magnetizing member 4 at a right angle or a substantially right angle. In the vibration oscillating device configured in this manner, for example, when an AC power source is connected to the wire 22 of the coil part 2, the body part 42 of the yoke part 4 is located at two positions 180 degrees apart, specifically, on the left side of the magnetizing member 6. Magnetic pole surface (N
The magnetic poles 64 are assumed to be magnetized to the poles) and the magnetic pole face 65 to the right (to be magnetized to the S poles) 65 are respectively arranged so that the polarities at the two positions are alternately the N pole and the S pole at high speed. Switch. Therefore, an attracting action and a repulsive action occur between the magnetizing member 6 supported by the supporting rods 71 and 72 and the body portion 42 of the yoke portion 4, and the magnetizing member 6 floats up in the space 5 under the influence of these actions. While moving, it moves back and forth along the straight line as indicated by arrow C. Vibration is generated due to the high-speed change of the position of the center of gravity accompanying the reciprocating movement of the magnetizing member 6. When the magnetized member 6 reciprocates, the curl portions 73, 74 of the support rods 71, 72 move in the direction of withdrawal from the recessed portions 43, 44 as shown by arrows A and B in FIG. Further, since the polarities are switched at high speed in the yoke portion 4, the range in which the magnetized member 6 reciprocates is set within the space 5. Therefore, the magnetized member 6 is connected to the yoke portion 6
It does not interfere with the body 42 of the. In FIG. 1, the movement limits of the two magnetic pole surfaces 64, 65 of the magnetizing member 6 are shown by imaginary lines, and the swing angles of the support rods 71, 72 are shown by θ. In this embodiment, since the magnetizing member 6 is supported by the supporting rods 71 and 72 made of a leaf spring material, even if the linear path along which the magnetizing member 6 reciprocates is not horizontal,
For example, even if it is vertical, it does not hinder the reciprocating movement of the magnetizing member 6. Further, since there is no sliding portion or rotating portion in the magnetized member 6 or the electromagnetic drive unit 1, no sound accompanying sliding or rotation is generated. Although the AC power supply is used as the power supply in the above description, as described above, the polarities of two portions of the body portion 42 of the yoke portion 4 separated by 180 degrees are N (S).
It is also possible to employ a power source that can be switched alternately between a magnetized state and a non-magnetized state, such as pole-pole-N (S) pole-pole, and even in such a case, the magnetizing member 6 reciprocates. And vibration is generated. In this embodiment, the magnetizing member 6 is constructed by disposing the metal members 62 and 63 on both surface sides of the permanent magnet 61, but the magnetizing member 6 may be constituted only by the permanent magnets. Further, the whole case may be covered with the case 9 as shown by an imaginary line in FIG. FIG. 3 is a plan view of an oscillating device according to an embodiment of the present invention. In this vibrating device, the magnetizing member 6 is held by one supporting rod 7. That is, the support rod 7 is provided with curl portions 77 and 78 at both ends thereof.
7, 78 are movably held in the respective recessed portions 43, 44 provided 180 degrees apart in the body portion 42 of the yoke portion 4 on both sides of the reciprocating movement path of the magnetizing member 6 so as to be movable in the outgoing and outgoing directions. There is. The magnetizing member 6 is held at the intermediate portion (the central portion in the embodiment) of the support rod 7. Here, the magnetized member 6 is
It is composed of a pair of permanent magnets 61, 61 and magnetic metal members 62, 63 arranged on the outer surface side thereof. Other configurations are the same as those described in FIG. 1 and FIG.
The same parts are designated by the same reference numerals and detailed description thereof is omitted. Even in such an oscillating device, the same operation as that described with reference to FIGS. 1 and 2 is achieved. FIG. 4 is a plan view of a vibrating device according to an embodiment of the invention according to claim 6, and FIG.
It is sectional drawing which follows the line. In this embodiment, the magnetizing member 6
However, it is held in a groove 25 formed in a bobbin 21 made of a magnetic material, specifically synthetic resin, so as to be capable of reciprocating along a linear path. Therefore, the above-mentioned support rods 7, 71, 72
Is unnecessary. In this embodiment, the other structure is similar to that described with reference to FIGS. 1 and 2, and therefore, the same parts are designated by the same reference numerals and detailed description thereof will be omitted. Even in such an oscillating device, the same operation as that described with reference to FIGS. 1 and 2 is achieved. However, in this embodiment, the magnetizing member 6
Rub against the groove wall surface of the groove portion 25 when reciprocating, but since the groove wall surface is a synthetic resin surface, the sliding noise generated when the magnetizing member 6 reciprocates is not so large, and is practically no problem. small. FIG. 6 is a vertical sectional side view of a vibrating device according to another embodiment of the invention according to claim 6. In this embodiment, the two magnetic pole surfaces 64 of the magnetizing member 6,
Between the respective 65 and the wall surface of the groove portion 25, the spring bodies 26 and 27, which are coil springs, are interposed and the magnetizing member 6 is provided.
Is held in the neutral position. In this embodiment, other configurations are the same as those described in FIG. 4 and FIG. In this embodiment, since the magnetized member 6 is supported by the spring bodies 26 and 27, the magnetized member 6 can be reciprocated even if the linear path in the groove 25 is not horizontal, for example, vertical. There is no hindrance to the reciprocating movement of 6. Further, also in such an oscillating device, the same operation as that described with reference to FIGS. 1 and 2 is achieved.

適用することができる。According to the vibration oscillating device of the invention having the structure described in claim 1, claim 2, claim 3, claim 4 or claim 5, the magnetized member is magnetized in the core while the magnetized member is in a floating state. Since it reciprocates in the direction orthogonal to the direction, the magnetic loss due to the space gap is suppressed to the minimum limit, and efficient vibrating operation is performed. Further, since the magnetized member does not have a sliding portion or a rotating portion, no sound is generated due to the sliding or rotating, which helps to increase the efficiency of the vibration generating operation.
In addition, since it is composed of the electromagnetic drive unit and the magnetizing member, it is possible to provide a vibrating device having a simple structure at low cost. Even if it is configured as described in claim 6, the same effect is exhibited. Further, according to the second or third aspect, the size of the expensive permanent magnet can be reduced by disposing an inexpensive metal member having magnetic susceptibility on both sides of the permanent magnet. However, the cost of the magnetizing member is reduced accordingly, which helps to keep the price of the vibrating device low. According to the fourth and fifth aspects, it is not always necessary to horizontally reciprocate the magnetized member. Therefore, it can be suitably applied to mobile communication means such as a mobile calling dedicated device and a mobile phone.
