as the door trim 50 which covers the inner panel 71 of a motor vehicle. [Selected figure] Figure 1
Speaker device
[0001]
The present invention relates to, for example, a speaker device which is mounted on a door of an
automobile or the like and whose sound quality emitted from the speaker is improved.
[0002]
For example, as shown in FIGS. 9 and 10, a speaker 130 is attached to an inner panel 171 of a
door of a car.
03-05-2019
1
The door of the car is an outer panel 191 made of steel plate which is a panel 170 on the
outdoor side of the car, an inner panel 171 made of steel plate which is fitted on the outer panel
191 and is a panel 170 on the indoor side of the car, A wood fiber-containing board material and
a woven door trim 150 (FIG. 9) so-called door lining 150 mounted on the indoor side of the room
171 are provided. The speaker 130 is attached to the inner panel 171.
[0003]
The speaker 130 converts the input electrical signal into an acoustic signal, and emits the
acoustic signal into space. The speaker 130 is configured to include a magnetic circuit unit 135
(FIG. 9) such as a magnet (not shown) or a voice coil (not shown) and a diaphragm 133 (FIG. 10)
such as cone paper. . By vibrating the diaphragm 133 (FIG. 10) back and forth by the magnetic
circuit unit 135 (FIG. 9), air is vibrated and sound is emitted from the speaker 130.
[0004]
The front-rear direction of the speaker 130 will be described. As shown in FIG. 10, the side
provided with the diaphragm 133 is referred to as the front side 130 a or the front side 130 a of
the speaker 130. Further, the side provided with the magnetic circuit portion 135 (FIG. 9) for
driving the diaphragm 133 of the speaker 130 is referred to as the back side 130 b or the back
side 130 b of the speaker 130. The definitions of "front", "back", and "front and back" in this
specification are for convenience in describing the speaker.
[0005]
To explain the state when sound is emitted from the speaker 130, the sound is emitted from the
front and back of the speaker 130 by the operation before and after the diaphragm 133 provided
in the speaker 130. The diaphragm 133 of the speaker 130 is moved back and forth to generate
compression waves, whereby a sound is produced from the speaker 130. The sounds emitted
before and after the speaker 130 when the speaker 130 is driven are considered to be the same
sound that is opposite in phase.
[0006]

In order to enjoy music with high sound quality in a car, it is considered important to adjust the
environment around the speaker 130, which is the source of sound. For example, when the plate
separating the front and rear of the speaker is omitted and the periphery of the speaker is not
maintained, the front and back sounds emitted from the speaker cancel each other, and the bass
generated from the speaker is difficult to hear It becomes a thing.
[0007]
As shown in FIGS. 9 and 10, in most cars, the door speaker 130 is incorporated in the inner panel
171 of the door, so the door panel 170 itself functions as an enclosure that improves the sound
of the speaker 130. It is supposed to be. The enclosure means one surrounding the speaker 130.
As an enclosure, the box etc. which surround a speaker are mentioned, for example.
[0008]
In order to further improve the sound quality in the car, as shown in FIG. 10, the service holes
175A, 175B, 175C, 175D opened in the door panel 170 are blocked with the anti-vibration
materials 185A, 185B, 185C, 185D. ing. In addition, in order to prevent the occurrence of
resonance between the speaker 130 and the door panel 170 when the speaker 130 attached to
the door panel 170 is sounded at a large volume or when it is sounded in deep bass. As shown in
FIG. 9, the inner baffle board 110 is assembled between the speaker 130 and the door panel 170.
The inner baffle board 110 is a vibration absorbing member.
[0009]
As shown in FIGS. 9 and 10, the inner baffle board 110 corresponds to the speaker 130
assembled to the door inner panel 171, and can be attached to a door having the speaker 130
incorporated into the inner panel 171. It is assumed.
[0010]
By incorporating the inner baffle board 110 between the speaker 130 and the door panel 170,
the sound quality emitted from the speaker 130 is improved.
03-05-2019

By doing this, in the case where the door speaker 130 is attached to the door panel 170, the
sound quality in the car can be improved.
[0011]
The baffle means a plate that blocks the front and back of the diaphragm 133. The fact that the
sound emitted from the back of diaphragm 133 is in reverse phase and flows around the front of
diaphragm 133 cancels out the positive phase sound and the negative phase sound, and the
sound quality is degraded. It is supposed to prevent. Also, the baffle may be taken to mean a
"stand" for vibration control to which the speaker 130 is attached. Reference numeral 180
denotes an inside handle 180 used when opening and closing a door of a car.
[0012]
By the way, in the thing by which the door speaker is integrated in the door trim 50 (substitute in
FIG. 6), it is considered that it is difficult to aim at the improvement of a sound quality. FIG. 6
shows a state in which the trim 50 in which the speaker is not mounted is viewed from the back
side. In order to improve the sound quality in the car, for example, a new hole (not shown) is
opened in the dent portion (73) corresponding to the speaker of the inner panel (71) (substitute
in FIG. 8) constituting the door, When a speaker is incorporated into the hole, there is also
concern that a water leak may occur in the vehicle through the hole, or a rust may be generated
on the inner panel (71) of the door.
[0013]
Also, when sound is emitted from the speaker mounted on the door trim (50) (substitute in FIG.
6), the operation directed to the front and back of the diaphragm of the speaker causes sound to
be emitted from the front and back of the speaker. Sounds have the property of trying to get
around each other at the door trim (50). Therefore, both sounds generated from the front and
back of the speaker collide with each other and cancel each other. Moreover, in the speaker
attached to the door trim (50), since there is no enclosure that functions as a speaker box, the
sound is also diffused to the rear side of the speaker. From these things, the sound emitted from
the speaker attached to the door trim (50) may be heard as distorted sound or muffled sound.
03-05-2019

[0014]
In addition, for example, when the speaker attached to the door trim (50) is sounded at a large
volume or when it is sounded in deep bass, resonance may be generated between the speaker
and the door trim (50) . From these things, in the speaker attached to the door trim (50), it is
considered that the original performance of the speaker can not be exhibited sufficiently.
[0015]
The present invention has been made in view of such circumstances, and an object thereof is to
provide a speaker device in which the sound quality emitted from the speaker is improved.
[0016]

corresponding to the front side of the speaker; In the speaker device provided with the speaker
mounted therebetween, a substantially cylindrical spacer extended from the speaker to the panel
is mounted on the rear side of the speaker, so that the rear side of the speaker is , The spacer,
and the panel (claim 1).
[0017]
According to this structure, since the rear side of the speaker is surrounded by the spacer and
the panel, the sound emitted from the speaker is prevented from being diffused to the rear side
of the speaker, and the sound emitted from the speaker is , Spread from the front side of the
speaker to the front of the speaker.
Therefore, the directionality of the sound is clarified, the sound quality is improved, and the bass
is more likely to be produced, providing a sound field full of sense of reality.
[0018]

[0019]
Thus, the sound emitted from the speaker is further spread from the front side of the speaker to
the front of the speaker.
Since the seal member provided on the spacer is in contact with the panel, the sound is unlikely
to leak to the outside from the space on the rear side of the speaker formed by being surrounded
by the spacer and the panel.
Therefore, the sound emitted from the speaker is emitted more toward the front of the speaker,
and the directionality of the sound is further clarified.
[0020]
It is preferable that the panel includes an inner panel that constitutes a door of a car, and the
trim is formed as a door trim that covers the inner panel of the car (claim 3).
[0021]
If a door provided with such a speaker device is assembled and used as a car door, it is possible
to enjoy high-quality music in the car.
[0022]
