DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to
an improvement of a vehicle interior acoustic device. As for the method of attaching the speaker
in the conventional in-vehicle acoustic device, as shown in Fig. 1 to Fig. 2, as shown in Fig. 1 and
Fig. 2 (· '1 INSTALLENT PAR HEAL 11 DOOR TRIM 2. Quarter trim 6, each piece 1 piece of
material such as bead elbow 4 (1),;, 715; ',, 7. . 1. j in such a manner that the center line 6 of the
speaker 5 is substantially vertical. However, in the method of mounting the above-mentioned
conventional speaker, (in particular, in particular, a coupe, a hard top, etc.), the inclined surface
of the front window or the rear window of the rear window is fixed to the surface In the case of a
sharply inclined plane with an acute angle with respect to (c), there was the ninth disadvantage. 1
The name generated from the speaker is reflected by the car body (crow song etc. of the front
wind), but the angle of the car body is Ji ((And, because the reflected sound is the same for the
passenger's ears, Also, listen to the distorted reverberation sound reflected (sound, the sound
effect is bad ~ · 02 sound emitted from the speaker is reflected by the car body (front wind crow
song etc.) and the same reflection 8 returns to the speaker , Is the speaker distorted without
proper vibration? ° 1, or the reflected sound and the direct radiation from the speaker interfere

with each other and it becomes better? 1(ハウリンク)となる。 (2) When the sound emitted
from the Toro speaker enters the area surrounded by the car body 2, the same sound becomes a
muffled sound. In order to solve the above problem, as shown in FIGS. 6 and 4, in order to direct
the center line 6 of the speaker 5 toward the ears of the occupant, with respect to the surface c
of the mounting member A of the vehicle body It is also conceivable to install it inclined.
However, in the case where the speaker 5 is provided by recessing the attachment member a as
shown in FIG. 6, in the case of a harness or trunk room existing on the inner side of the
attachment member A, interference with other objects or the like must be taken into
consideration Nevertheless, it is difficult to provide the speaker 5 on the inner side of the
mounting member A due to its structure (· 5 problem. Further, as shown in FIG. 4, when the
speaker 5 is provided so as to protrude outward from the attachment member a, there is a
problem as described in 9 below. 1 When the speaker 5 is provided by protruding a part of the
instrument panel with respect to the first power H, the square field of view becomes worse. 2
Door trim or quarter Torino, if the speaker 5 is provided by letting it protrude (3) partly, hamper
the interior space of the passenger compartment. 6 When a speaker 5 is provided by protruding
a part of the rear shelf, a space capable of placing an object on the shell Z is sandwiched.
The present invention solves the above-mentioned problem, it is directed to the interior of the
vehicle interior 5 VC body - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - A reflective reflective member for reflecting in a desired direction in the room. Which is
provided in front of or behind the speaker integrally with or separately from the speaker, or to
the vehicle body or interior member which is located at the front of the same speaker. In
summary of the sound system, the convex emitted from the loudspeaker is reflected by the
appropriately adjusted reflective member, rotated in the easy-to-hear direction of the i, and the 1
L 1 F effect is improved. An embodiment of the present invention will be described with
reference to FIGS. 5 to 7. 10はインストルメントパネル12. Door (4) Deafness trim 14. クォ

facing the interior of the vehicle, and on a part of the mounting member 1 o. In the case of this
embodiment, a number of diagonal holes 19 are drilled in the surface 11 of the mounting
member. 2 o is a conventional speaker, the speaker body 22. Cone paper 24 ° Frame 26. Arrow
paper 28. 6). In FIG. 6, the center line of the speaker 2 o is located below the hole 19 bored in
the attachment member 1 o and the center line of the speaker 2 o is on the surface 11 of the
attachment member 10 , And is secured to the mounting member 1 o with a bolt / nut 62. A
casing 68 having a cross section having a cross section with a reflecting member 9 as shown in
FIG. 7 and a side plate 66 forming a passage 2 in the case of the present embodiment 9, and a
pair of opposing side & 66 of the casing 68 A plurality of reflecting plates 44 which extend
directly and are pivotally supported by bins 42 at approximately the center of both side plates 66
and are formed of a hard material such as metal or synthetic resin and a plurality of reflecting
plates 44 respectively provided at the lower ends of the two adjacent reflecting plates 44 (5) · 11,
which is provided between the direction 011 of the speaker kit 50 and the mounting member 10

and is fitted in the frame 26. With the above configuration 2 small (small) · When listening to a
signal emitted from a sound source such as a radio or the like via the speaker 20, the sound
emitted from the speaker 20 spreads around the center line 48 of the speaker 20 When the
sound passes through the passage 2 of the reflection member 34, the same name is reflected by
the reflection plate 44, and the directivity of the sound is controlled. Therefore, the squared U
has no inflation bolus 12 C ° · Reflective member disposed at the front of the speaker 20
provided in the helical elf 18:) 40 Do not hurt the reflector 44 at an appropriate angle - If it
adjusts accordingly, directivity is controlled by the 2 reflector 44, and rice is directly or 7 c +
window.
Since it is reflected once in the direction of the cabin of the rear window and propagated to the ith power, the first power - is the distorted reverberation sound, the beat sound, the booming
reflected many times on the body such as the glass surface? I can listen to clear old days without
any one (can produce excellent convex (6) sound effects. Also, if the ninth power i is
appropriately adjusted by the Reno 15 y which does not hurt the reflecting member 640
reflecting plate 44 disposed at the front part of the speaker 20 provided in the door trim 14 or
the quarter trim 16, the directivity becomes 11 People-controlled sounds are propagated directly
to the passengers, so that they can listen directly to clear sounds and produce excellent acoustic
effects. In the above embodiment, the reflecting portion A '34 is provided between the stria 30 of
the speaker 2 o and the mounting member 10, but it may be fitted in the arrow paper 28 of the
speaker 20 as shown in FIG. 8, As shown in FIG. 9, the 9 reflecting member 64 may be provided
separately from the speaker 20 and may be installed in the opening 50 of the mounting surface
and fixedly attached to the mounting member 10 with the bolt and nut 52 together with the
speaker 20 , The speaker 20 and the reflecting member 64 may be provided on the burning side
in the hole 19 portion of the mounting member 10. Also, an instrument panel 12, a door trim 14
facing the interior of the vehicle interior. A speaker 20 may be attached to a member existing in
the rear of the quarter trim 16 (7) or the rear shelf 18, and the reflecting member 34 may be
provided integrally with or separately from the same speaker in front of the speaker 64 may be
provided in the vicinity of a vehicle body such as a rear window.
