DESCRIPTION JPH0615395
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
on-vehicle speaker, and more particularly to an on-vehicle speaker capable of freely changing the
position of the speaker.
[0002]
2. Description of the Related Art In a conventional on-vehicle speaker, the surface (generation
surface) for emitting the sound has been fixed. That is, the directivity of the sound was fixed.
[0003]
[0003] However, such a prior art is not necessarily limited to the voice of its own preference
depending on the driver's height, position, or the range of preference Sometimes, I had to hear
unpleasant noises, but sometimes I was forced to suffer because I could not change the
directivity of the sounds.
[0004]
The present invention makes it possible to change the direction of the generating surface of the
speaker by freely turning the inner mold on which the speaker is attached, and to freely select
the driver's favorite range. Intended to provide.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention
relates to an outer mold having a cover mold and a base mold, and either to the left or right or to
the front or back direction of the outer mold. A first inner mold pivotally supported, and a
speaker attached to the first inner mold, and / or disposed between the base mold and the first
inner mold, And a second inner mold pivotally supported in a direction perpendicular to the
rotation direction of the inner mold, and a speaker attached to the second inner mold.
[0006]
[Operation] By attaching the speaker to the inner mold on the front side of the two inner molds
that can be pivoted back and forth, right or left, the direction of the speaker's generation surface
can be freed
[0007]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present
invention will now be described with reference to the attached drawings.
[0008]
FIG. 1 is a cross-sectional view of the in-vehicle speaker of the present invention shown in FIG.
[0009]
FIG. 2 is a front view.
[0010]
FIG. 3 is a cross-sectional view taken along the line B-B of FIG.
[0011]
The on-vehicle speaker 1 comprises an outer mold 10 having a cover mold 11 and a base mold
12, a first inner mold 20 pivotally supported by the outer mold 10 in the lateral direction, and a
first inner. And a speaker 40 attached to the mold 20.
[0012]

The outer mold 10 comprises a frame-shaped cover mold 11 in which an opening 111 is formed
and a frame-shaped base mold 12 in which an opening 121 is formed. The vertical center of the
contact surface of the cover mold 11 and the base mold 12 The hemispherical concave surfaces
112 and 122 opposed to each other on the axis are formed, and when they are put together, they
are configured to be a pair of spherical pivot receivers 13.
The cover mold 11 and the base mold 12 are fixed by an adhesive or the like after the first inner
mold 10 and the speaker 40 are pivotally supported.
[0013]
The first inner mold 20 has a circular frame shape, and the mounting hole 21 of the speaker 40
is formed at the center, and a pivot 22 is formed so as to protrude on the outer periphery on the
vertical axis.
Then, the pivot 22 is fitted to the spherical pivot receiver 13 of the first inner mold 10 and
pivotally supported.
[0014]
Therefore, in this embodiment, the speaker 40 pivots about the vertical central axis, but if the
pivot 22 is formed on the horizontal axis, it will be pivoted in the front-rear direction.
[0015]
FIGS. 4 to 6 show a second embodiment, in which the speaker 40 is configured to be pivotable
back and forth, and to the left and right.
In the configuration similar to that of the first embodiment, the same symbols are used.
[0016]
The in-vehicle speaker 1 of this embodiment is mounted on an outer mold 10 having a cover

mold 11 and a base mold 12, a first inner mold 20, a second inner mold 30, and a first inner
mold. And the speaker 40.
[0017]
The outer mold 10 comprises an arm-shaped cover mold 11 having a circular opening 111 on its
front surface and a tray-shaped base mold 12, and a pair of spherical shapes on the horizontal
center axis of the base mold 12. A pivot receiver 14 is formed.
Then, after the first and second inner molds 10 and 20 and the speaker 40 are pivotably
supported on the base mold 12 by the cover mold 11, the cover mold 11 is formed by an
adhesive or the like.
[0018]
The first inner mold 20 has a circular frame shape, and the mounting hole 21 of the speaker 40
is formed at the center, and the pivot 22 is formed so as to protrude on the outer periphery on
the vertical axis.
[0019]
The second inner mold 30 is substantially similar to the outer mold 10, and has an arm-shaped
cover mold 31 having a circular opening 310 on its front surface, and a tray-shaped base mold
32.
Then, a hemispherical pivot receiver 311 is formed on the inner circumference of the opening
310 of the cover mold 31 on the vertical axis, and similarly, the hemispherical pivot is also
formed on the inner circumference 321 on the vertical axis of the opening 320 of the base mold
32. A receptacle 322 is formed, which together constitute a pivot receptacle 33.
In addition, pivots 323 are formed on both ends of the horizontal axis of the base mold 32.
[0020]

The speaker 40 is mounted with a bolt 23 and a nut 24 around the mounting hole 21 of the first
inner mold 20 with the generation surface facing the circular opening 111 formed on the front
surface of the outer mold 10.
[0021]
The first inner mold 20 to which the speaker 40 is attached is fitted in a pivot receiver 33 formed
on the inner periphery of the opening 310 of the cover mold 31 of the second inner mold 30 on
the vertical axis. It is pivotally supported in the horizontal direction, that is, in the left and right
direction about the axis.
Further, the second inner mold 30 is fitted with a pair of spherical pivot receivers 14 formed on
the horizontal center axis of the base mold 11 of the outer mold 10, with the pivots 323 formed
on the outer periphery on the horizontal axis. It is pivotally supported in the vertical direction,
that is, in the front-rear direction about an axis.
[0022]
Therefore, when adjusting the direction of the sound in the back and forth direction, the second
inner mold 30 is pivoted up and down about the pivot 323, and when the direction of the sound
is adjusted in the left and right direction, The inner mold 20 is rotated to the left and right
around the pivot 22.
[0023]
As described above, the speaker is attached to the first inner mold which can be turned to the left
and right with respect to the outer mold, and the directivity of the sound in the left and right
direction is adjusted, By pivotally supporting the inner mold 2 in the back and forth direction, the
direction of the generation surface of the speaker can be freely selected, for example, by
adjusting the directivity of the sound in the left and right direction. It can provide a voice range
of your choice.
