- the protruding portion 46 b has the same inner diameter as the opening hole 46 a and is continuous, and has an outer diameter that can be fitted into the vibrating portion of the magnet 45 and the mounting hole 45 c from above.
- the tip of the projection 46 b is formed so as to have a predetermined gap with the one end surface 44 a of the conductor coil 44 so as to be opposed to each other at a height position.
- the other yoke 47 is formed of a disc-shaped flat plate member which is attached in contact with the other end surface 45b of the magnet 45, and has a cylindrical end surface 47a on the magnet 45 side.
- a projection 47 b is formed.
- the protruding portion 47 b has an inner diameter into which the front end of the column 43 can be inserted, and an outer diameter that can be inserted into the vibrating portion mounting hole 45 c of the magnet 45.
- the distal end of the projection 47 b is set to be at a height position facing the other end surface 44 b of the conductor coil 44 with a predetermined gap.
- a through hole 47c for inserting the mounting port 41a is provided at the center of the yoke 47.
- the through hole 47c has an inner diameter large enough to be separated from the mounting port 41a with a predetermined gap.
- each of the yokes 4 6 and 4 7 is smaller than the outer diameter of the magnet 45, and the outer periphery of the magnet 45 is more radial than the yokes 4 6 and 4 7 in order to prevent a magnetic short circuit. It is formed in a size protruding outward.
- a yoke 46 is attached to one end surface 45 a of the magnet 45, and a conductor is connected from the other end surface 45 b side.
- the support 43 having the coil 44 is inserted, and the support 43 is fixed to the attachment 41 by the mounting port 41a and the mounting nut 41b.
- a cushioning material 49 is interposed between the yoke 47 and the column 43 and between the yoke 47 and the mounting nut 41c, and the vibration of the vibrating part 42 is transmitted to the driving part 48. Is suppressed.
- the attachment 41 is attached to the trunk of the tree 5 by a fastening member such as a rope, and the connection terminal is connected to the output terminal of the tape deck to be set.
- the conductor coil 44 can vibrate in the direction perpendicular to the axial direction of the column 43 within the vibrating portion ⁇ the mounting hole 45 c. Therefore, a large vibration can be generated in the column 43, and the vibration can be transmitted from the attachment 41 to the trunk of the tree 5, and a large volume of sound can be generated from the tree 5.
- the protrusions 46 b, 47 b from the yokes 46, 47 toward the conductor coil 44 The distance between the yoke 46 and the yoke 47 can be shortened by interposing the conductor coil 44 between the tips, and the magnetic force strength between the tips is squared to the distance. It can be increased proportionally. Therefore, a stronger magnetic force can be applied to the conductor coil 44, and the conductor coil 44 can be greatly vibrated. This allows the louder music to be played from tree 5.
- the vibrating portion 42 can be vibrated greatly, and a significantly larger sound can be generated from the tree 5 force than in the past.
- the column 43 is made of a non-magnetic material, the inductance can be reduced, the frequency characteristics can be improved in the high frequency range, and the output of the high frequency can be increased.
- the support 43 is formed of a thin cylindrical member, the support 43 can be vibrated so as to expand and contract in the radial direction by the vibration of the conductor coil 44. Therefore, the vibration of the strut 43 can be reliably transmitted from the attachment 41 to the tree 5, and a higher volume music can be played.
- the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention.
- a base material or the like has been described as an example of the sound generating member holding means.
- a non-magnetic material that can efficiently transmit the vibration of the conductor coil is used. Any other material may be used, for example, a pipe made of synthetic resin.
- the gap between the conductor coil 13 and the magnet 15 or the gap between the conductor coil 23 and the yokes 26 and 27 is set to be about 1 to 2 mm, but it is set to be narrower or wider than this. Is also good.
- FIG. 1 is a longitudinal sectional view illustrating a configuration of a sound generating device according to a first embodiment.
- FIG. 3 is an exploded view of the sound reproducing device. [Fig. 3]
- Fig. 6 is a longitudinal sectional view illustrating a configuration of a sound generating device according to a second embodiment.
- FIG. 3 is an exploded view of the sound generator.
- FIG. 6 is a longitudinal sectional view illustrating a configuration of a sound generating device according to a third embodiment.
- FIG. 2 is an enlarged view of a main part of the sound generator.
- FIG. 14 is a longitudinal sectional view illustrating a configuration of a sound generating device according to a fourth embodiment.
