[0039]
<Drive Unit> The drive unit 40 vibrates the diaphragm 20 in accordance with the supplied
electric signal.
A plurality of driving units 40 are provided in a line at intervals in the longitudinal direction of
the frame 30. Specifically, one each is provided at a position corresponding to the holding
portion 36 provided in the frame 30.
[0040]
Each drive unit 40 includes a yoke 41 attached to the holding unit 36, a magnet 42 attached to
the yoke 41, and a coil 43 that vibrates due to the interaction of the magnetic field formed by the
magnet 42.
11-05-2019
12
[0041]
The yoke 41 has a cylindrical outer shape, and is constituted of a peripheral wall surface and a
bottom surface.
The upper part of the yoke 41 is open. The yoke 41 is fixed to the holding portion 36 in a state
of being fitted into a hole formed at the center of the holding portion 36.
[0042]
The magnet 42 is formed in a cylindrical shape, and is fixed to the center of the bottom surface
of the yoke 41 so that the axial direction extends vertically. A neodymium magnet is preferably
used as the magnet 42. However, as the magnet 42, a ferrite magnet or an alnico magnet can
also be used. One end of the magnet 42 in the longitudinal direction is bonded to the center of
the yoke 41 with an adhesive or the like.
[0043]
The coil 43 is formed by cylindrically winding a conductor made of copper or a copper alloy. The
coil 43 is formed by winding a conductor a predetermined number of times preset using a coil
winding machine so as to have a desired inner diameter and outer diameter.
[0044]
The coil 43 is attached to the back surface of the diaphragm 20. The coil 43 attached to the
diaphragm 20 is disposed between the yoke 41 and the magnet 42 so that the peripheral wall
surface of the yoke 41 is positioned on the outer side and the magnet 42 is positioned on the
inner side. Also, the coil 43 is maintained in the horizontal position by the damper 44. The
damper 44 is a circular member as shown in FIG. 1 and FIG. 2, and peaks and valleys are
sequentially arranged in the radial direction and formed in a wave shape. The damper 44 is
provided with a hole for passing the coil 43 at its central portion, and holds the coil 43 at the
central portion, while the outer periphery of the damper 44 is attached to the holding portion 36
of the frame 30. The coil 43 is held by the damper 44 on the holding portion 36 of the frame 30.
11-05-2019
13
For this reason, the diaphragm 20 integrated with the coil 43 vibrates back and forth.
[0045]
<Drive Unit> The three coils 43 are configured as a set of units by a unit plate 50 which is unit
means. The unit plate 50 is a thin plate elongated by aluminum or aluminum alloy or the like.
The unit plate 50 is formed with holes at predetermined intervals in the longitudinal direction.
The spacing of the holes corresponds to the spacing of the holding portions 36 provided on the
frame 30. One end side in the axial direction of each of the three coils 43 is passed through a
hole formed in the unit plate 50, fixed to the unit plate 50, and mutually connected.
[0046]
The unit means is not limited to such aluminum or aluminum alloy, and other metal materials,
resin, paper, wood chips can also be used. Moreover, a unit means is not limited to the aspect
using such a member. As a unit means which does not use a member, it can mention printing a
mark in the position where coil 43 of diaphragm 20 is attached, for example, or giving
unevenness. When printing, unevenness, etc. are attached to the diaphragm 20 to unitize the coil
43, unitization is performed by adhering the coil 43 to the diaphragm 20 by adhesion or the like.
[0047]
One end side of the unitized coil 43 inserted into the hole of the unit plate 50 is attached to the
back surface of the diaphragm 20. When the unitized coils 43 are attached to the diaphragm 20,
each coil 43 is aligned with the position of the drive unit 40 configured by the respective coils
43. At that time, the circumferential wall surface of the yoke 41 is positioned outside the coil 43
and the magnet 42 is positioned inside the coil 43.
[0048]
The unitization of the coils 43 enables the coils 43 to be attached to the diaphragm 20 at
predetermined positions, since the spacing between the coils 43 can be set to a dimension as
11-05-2019
14
designed. Therefore, the unitization of the coil 43 can form the necessary clearance between it
and the magnet 42 to be combined. Moreover, unitization of the coil 43 is such that the plurality
of coils 43 can be efficiently attached to a predetermined position.
[0049]
In such a coil 43, three unitized coils 43 are electrically connected in series. The units formed of
the three coils 43 may be connected in either series or in parallel.
[0050]
As described above, although the case where one set of drive unit 51 is configured by three drive
units 40 by unitizing three coils 43 has been described, two drive units 40 configure one set of
drive unit Alternatively, the drive unit may be configured by four or more drive units 40. In
addition, although the case where the coil 43 is unitized has been described as an example, two
or more magnets 42 are unitized to form one set of drive unit 51, or both the coil 43 and the
magnet 42 are unitized to drive The unit 51 can be configured. Further, one set of drive unit
units 51 may be configured by two or more drive units 40 as a whole.
[0051]
An example in which the magnet 42 is unitized and the coil 43 is directly bonded to the
diaphragm 20 will be described with reference to FIG.
[0052]
As shown in FIG. 4, the three coils 43 are bonded in one row at a constant distance in the
longitudinal direction of the diaphragm 20 at the center in the width direction of the diaphragm
20.
On the other hand, the three magnets 42 are made into one set of units by a unit plate 70 which
is unitization means. The distance between the three unitized magnets 42 is the same as the
distance between the coils 43.
11-05-2019
15
[0053]
The unitization of the magnets 42 enables the magnets 42 to be attached to the frame 30 at a
predetermined position, since the spacing between the magnets 42 can be set to the designed
dimensions. Therefore, unitization of the magnet 42 can form a required clearance between the
coil 43 combined. Moreover, unitization of the magnet 42 enables it to be able to efficiently
attach the some magnet 42 to a predetermined position.
[0054]
Even when the plurality of magnets 42 are unitized, when combined with the coil 43 attached to
the diaphragm 20, the position of the magnet 42 and the position of the coil 42 do not
completely match, and an error occurs between them. May occur. The unit plate 70 which is a
unit means is provided with an adjusting margin 71, and when the magnet 42 and the coil 43 are
combined, the position of the magnet 42 can be finely adjusted. The unit plate 70 shown in FIG.
4 is an example in which an adjustment margin 71 capable of adjusting the position of the
magnet 42 in the longitudinal direction is provided. The positional deviation between the magnet
42 and the coil 43 may also occur in the width direction. Therefore, the adjustment margin 71
may be formed so as to be able to adjust the position of the magnet 42 in any of the longitudinal
direction and the width direction.
[0055]
Next, with reference to FIG. 5, the case where both the magnet 42 and the coil 43 are unitized
will be described.
[0056]
The three coils 43 are configured as a set of units by a unit plate 50 which is unit means.
Similarly, the three magnets 42 are made into a set of units by a unit plate 70 which is
unitization means. The distance between the three unitized coils 43 and the distance between the
three magnets 42 coincide with each other.

Since unitization of both the magnet 42 and the coil 43 can arrange the spacing between the
magnets 42 and the spacing between the coils 43 as designed, the magnet 42 can be attached to
a predetermined position of the frame 30. The coil 43 can be attached to the diaphragm 20 at a
predetermined position. Therefore, unitization of both the magnet 42 and the coil 43 can form a
necessary clearance between the coil 43 to be combined more than when uniting only the
magnet 42 or when uniting only the coil 43 it can.
[0058]
In addition, even if the position of the magnet 42 and the position of the coil 43 are slightly
misaligned, the adjusting plate 71 is provided on the unit plate which unitizes the magnet 42 so
that the position of the magnet 42 can be finely adjusted. You should keep it.
[0059]
In the speaker unit 10 having the above configuration, when current flows in the coil 43, the coil
43 moves in the vertical direction by the interaction of the magnetic field formed by the magnet
42 and the magnetic field formed by the coil 43.
Since the coil 43 forms a magnetic field having a strength corresponding to the flowing current
value, the amount of movement of the coil 43 is determined by the flowing current value. When
the coil 43 moves in the vertical direction, the diaphragm 20 to which the coil 43 is attached
vibrates in accordance with the amount of movement of the coil 43. The speaker unit 10
generates a sound by such an action. Since the speaker unit 10 includes the coil 43 for each
drive unit 40, the inductance of the coil 43 is dispersed, and the drive current can be reduced.
