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. Particularly, in the vibration oscillating device configured as described in claim 3 , although the size of the permanent magnet can be reduced, a magnetic member having magnetism disposed on both sides of the permanent magnet is provided. Ru can increase magnetic efficiency by the action. In addition, claim 1 and claim 2
The vibrating device configured as described in (1) has a simplified structure for supporting the magnetized member in a floating state. Also ,
Since band magnetic member is supported by the support rod made of a leaf spring material, by previously defining a spring force of the support rod appropriately, always it is not necessary to reciprocate horizontally magnetized member. 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 .

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 claims 1 and 3 , and FIG. 2 is a line II-I in FIG.
It is sectional drawing which follows the I line. In this vibration exciter, the electromagnetic drive unit 1 includes a coil unit 2 formed by winding a wire rod 22 made of a conductor around a bobbin 21 made of synthetic resin.
An iron core 3 inserted into the center hole 23 of the bobbin 21 of the coil portion 2 and surrounded by the coil portion 2, and a disc portion 4
Iron 1 is crimped and coupled to an iron core 3, and a cylindrical body 42 (which may be a polygonal cylinder) is integrally erected from the outer peripheral portion of the disc portion 41 so as to surround the coil portion 2. And a yoke portion 4 made of a metal material having magnetic susceptibility. 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, the polarities of the two portions of the body portion 42 of the yoke portion 4 separated by 180 degrees are switched at high speed alternately to the N pole and the S pole. Also, depending on the type of power source connected to the wire 22 of the coil part 2,
It is also possible to alternately switch the polarities of two portions of the body portion 42 of the yoke portion 4 separated by 180 degrees between a magnetized state and a non-magnetized state such as N (S) pole-nonpolar-N (S) pole-nonpolar. is there. 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. Also, the support rod 7
Each of the distal end portions of the reference numerals 1, 72 is provided with a pair of mounting piece portions 75, 75, 76, 76 that are bent in mutually opposite directions, and these mounting piece portions 75, 75, 76, 7 are provided.
6 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. Perspective direction to the axis of
That is, it is held so as to be movable in the outgoing and outgoing directions (indicated by arrows A and B). The magnetizing member 6 is supported by the supporting rods 71 and 72 with a slight gap 8 with respect to the iron core 3, and no external force is applied to the supporting rods 71 and 72. Then, as shown in FIG. 2, the axis L-L of the iron core 3 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, two positions 180 degrees apart of the body part 42 of the yoke part 4, specifically,
The polarities of the two locations facing the left magnetic pole surface (assumed to be magnetized to the N pole) 64 and the right magnetic pole surface (assumed to be magnetized to the S pole) 65 of the magnetized member 6 are N.
The pole and the S pole are alternately switched at high speed. 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 , the vehicle 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. The magnetizing member 6
When the support rods 71 and 72 are reciprocated, the curl portions 73 and 74 of the support rods 71 and 72 are depressed as shown by arrows A and B in FIG.
Move in the direction of leaving and entering 3,44. 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 does not interfere with the body portion 42 of the yoke portion 6. In FIG. 1, the movement limits of the two magnetic pole surfaces 64 and 65 of the magnetizing member 6 are shown by imaginary lines.
The swing angle of the support rods 71 and 72 is indicated by θ. In this embodiment, the support rods 71 and 7 in which the magnetizing member 6 is made of a leaf spring material.
Since it is supported by 2, the reciprocating movement of the magnetizing member 6 is not hindered even if the linear path along which the magnetizing member 6 reciprocates is not horizontal, for example, vertical.
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, one of the body parts 42 of the yoke part 4 is used.
N (S) pole-no pole-N
It is also possible to employ a power source that can be switched alternately between the magnetized state and the non-magnetized state such as (S) pole-non-polarity. In such a case, the magnetizing member 6 reciprocates to generate vibration. To do. The case 9 may be entirely covered as shown by the phantom line in FIG. FIG. 3 is a plan view of an oscillating device according to an embodiment of the invention as defined in claim 2 . 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 end portions thereof.
78 are movably held in the respective recessed portions 43 and 44 provided at 180 degrees apart in the body portion 42 of the yoke portion 4 on both sides of the reciprocating movement path of the magnetized member 6. 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 composed of a pair of permanent magnets 61, 61 and metal members 62, 63 having magnetism disposed on the outer surface side thereof. Other configurations are similar to those described with reference to FIG. 1 and FIG. Even in such an oscillating device, the same operation as that described with reference to FIGS. 1 and 2 is achieved.
