[0004]
In high-end cars in particular, in addition to regular speakers, a tweeter, which is a dedicated
speaker for the high-frequency range, is also installed.
The inventor of the present invention has made earnest studies to achieve the miniaturization as
much as possible while maintaining the noise preventing function, for a speaker mounting panel
of a type in which the speaker and the tweeter are attached together.
[0005]
Then, the tweeter's harness connecting portion is positioned on the front side of the speaker
mounting panel, and the tweeter harness supporting portion is integrally provided on the front
side of the speaker mounting panel while maintaining the noise preventing function. We came to
find that it is extremely effective in achieving miniaturization.
[0006]
The present invention has been made based on the background as described above.
An object of the present invention is to provide a speaker attachment panel of a type in which a
speaker and a tweeter are attached together, which can be miniaturized while maintaining an
abnormal noise prevention function.
[0007]
The present invention relates to a speaker mounting panel provided in a vehicle compartment of
02-05-2019

a car, and a speaker fitting hole into which the speaker is fitted such that the harness connecting
portion of the speaker is positioned behind the speaker mounting panel, and the harness
connecting portion of the tweeter Provided on the front side of the speaker mounting panel, and
a tweeter insertion hole into which the tweeter is fitted so that the speaker mounting panel is
positioned on the front side, a tweeter harness penetrating portion penetrating from the back
side to the front side of the speaker mounting panel And a tweeter harness support portion on
which the tweeter harness is supported, wherein the tweeter harness support portion is
integrally formed with the speaker mounting panel.
[0008]
According to the speaker mounting panel according to the present invention, the tweeter harness
connection portion is positioned on the front side of the speaker mounting panel, and the tweeter
harness support portion is provided on the front side of the speaker mounting panel. In addition
to downsizing, the tweeter harness can be securely supported to ensure the function of
preventing noise generation by the tweeter harness.
By directly or indirectly supporting the speaker harness with the tweeter harness securely
supported in this manner, it is possible to guarantee the function of preventing noise from being
generated by the speaker harness.
[0009]
Furthermore, according to the findings of the inventor of the present invention, by integrally
forming the tweeter harness support portion with the speaker mounting panel, the rigidity of the
speaker mounting panel is improved, and the occurrence of resonance in the speaker mounting
panel is also effective. It is prevented.
[0010]
It is preferable that the tweeter harness penetration portion be provided adjacent to the speaker
insertion hole.
In this case, the work for drawing the tweeter harness is easy, and it is also easy to form the
tweeter harness penetration portion as small as possible, so that the occurrence of so-called
02-05-2019

sound leakage is also suppressed. In particular, when the speaker insertion hole is substantially
circular, it is preferable that the tweeter harness penetration portion be formed as a notch
extending in a tangential direction of the speaker insertion hole. In this case, the tweeter harness
penetrating portion can be formed as a minimal area, and it is easy to substantially close the
tweeter harness penetrating portion by the tweeter harness after the tweeter harness is routed.
Thus, the occurrence of so-called sound leakage can be suppressed more effectively.
Furthermore, in this case, it is preferable that a slope be provided in the thickness direction of
the speaker mounting panel from the tweeter harness penetrating portion to the tweeter harness
supporting portion on the front side of the speaker mounting panel. With such a slope, the path
of the tweeter harness routed from the back side to the front side of the speaker mounting panel
is more reasonable (the degree of stress generation is smaller).
[0011]
The tweeter harness support portion is constituted of, for example, a pair of sandwiching pieces
projecting to the front side of the speaker attachment panel, and can hold and support the
tweeter harness.
[0012]
The tweeter harness is preferably bundled with the speaker harness on the back side of the
speaker mounting panel.
As a result, the speaker harness can be reliably supported, and the function of preventing noise
from being generated by the speaker harness can be assured more reliably. Moreover, since such
arrangement does not cause the speaker harness to fall even when the speaker is removed, socalled serviceability (workability) is good.
[0013]
Further, the present invention is an automobile characterized by comprising a speaker mounting
panel having any of the features described above, and a cover panel which covers the front side
of the speaker mounting panel.
