DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement
of a vehicle interior sound system. The method of mounting the speaker in the conventional
vehicle interior sound device is as shown in FIG. 1 and FIG. 2 (. '1 instrument panel 11 door trim
2. 6. each trim 1 of the quarter trim 6 or the like, such as the heavy duty elf 4 (1); 715; ', . 1. The
center lines 6 of the speakers 5 were attached to the surface of j so as to be substantially vertical.
However, in the method of mounting the above-mentioned conventional speaker (in particular, in
the case of coupe, hard top, etc.), the crow's inclined surface of the front or rear window is the
surface of the mounting member of the above speaker In the case of a steep inclined surface with
an acute angle to the C, there is a defect as follows. (1) Although the name generated from the
speaker is reflected on the vehicle body (crowd of the front wind, etc.), the angle of the vehicle
body is ci (, the sound reflected is the same towards the passenger's ear (и Also hear the distorted
reverberation that is reflected (meaning that the sound effect is bad-the sound emitted from the
02 speaker is reflected by the vehicle body (crowd of front wind etc.) and the reflection 8 returns

to the speaker , Is the speaker distorted without proper vibration? Does it become 1 ░ or beats
due to interference between the reflected sound and the direct i from the speaker? ??????
?????? (2) When the sound emitted from the toro-speaker 2 enters a place surrounded by
the vehicle body, the same sound becomes a booming sound. Further, in order to eliminate the
above problems, as shown in FIGS. 6 and 4, the center line 6 of the speaker 5 is directed to the
occupant's ear with respect to the surface of the mounting member B of the vehicle body. It is
also conceivable to mount it at an incline. However, as shown in FIG. 6, when the mounting
member B is recessed and the speaker 5 is provided, in the case of a harness or trunk room
existing on the inner side of the mounting member B, interference of other objects etc. If it is
difficult to provide the speaker 5 on the inner side of the mounting member B due to its
structure, there are problems (5). Further, as shown in FIG. 4, when the speaker 5 is provided so
as to protrude outward of the mounting member A, there are the following problems. (1) When
the speaker 5 is provided with a part of the instrument panel projecting, the visibility with
respect to the square H becomes worse. When a part of the 2-door trim or the quarter-torino is
made to project (3) and the speaker 5 is provided, the living space in the vehicle compartment is
disturbed. When a part of the rear shelf is made to project and the speaker 5 is provided, a space
in which an object can be placed on the shell Z becomes stagnant.
The present invention solves the above-mentioned problems, and the 5 VC vehicle body directed
to the vehicle interior is a speaker mounted on an interior member of the vehicle interior, and a
convex emitted from the speaker transmitted to the vehicle interior is the same vehicle A yellable
reflective member for reflecting in a desired direction in the room. The vehicle interior is
characterized in that it is provided in the front of the speaker integrally or separately with the
above speaker, or is located in front of the same speaker, and can be used for the vehicle body or
the interior member. When the sound emitted from the speaker is reflected by the reflection
member appropriately adjusted and turned to the direction in which the power i can be easily
heard and the 1L1F effect is improved, the sound effect is produced. One embodiment of the
present invention will be described with reference to FIGS. ?????????????????
Door (4) fence trim 14. ?????????? The rear shelf 18 is a mounting member that
indicates a vehicle body panel or the like facing the interior of the vehicle, and is a part of the
mounting member 1o. In the case of the present embodiment, a large number of diagonal holes
19 are formed in the surface 11 of the mounting member (иииииииии 2o is a conventional speaker, and
the speaker body 22. Corn paper 24 ░ frame 26. Arrows 28. Neno) 30 or the like, which is
located below the hole 19 drilled in the mounting member 1 o in FIG. 6, and the center line of the
speaker 2 o is directly connected to the surface 11 of the mounting member 10. So as to be fixed
to the mounting member 1 o with the bolt nut 62. As shown in FIG. 7, 64 is a reflecting member
as shown in FIG. 7, and in the case of this embodiment, a casing 68 of a 1 "cross section
comprising side plates 66 forming passages 2 and a substantially east side between a pair of
facing sides & 66 A plurality of reflecting plates 44 formed of a hard material, such as metal or
synthetic resin, supported by a bottle 42 and extending substantially straight at the approximate

center of both side plates 66, and the lower ends of two adjacent reflecting plates 44 respectively
It is composed of a pivotally supported connecting rod 46 and (5) 11 and is provided between
the 011 end of the speaker kit 50 and the mounting member 10 and fitted in the frame 26. With
the above configuration, when the signal emitted from the speaker 20 is heard as a sound
through the speaker 20, the sound emitted from the speaker 20 spreads around the center line
48 of the speaker 20 (и However, when the sound passes through the passage 2 of the reflecting
member 34, the same name is reflected by the reflecting plate 44, and the directivity of the
sound is controlled. Thus the first power U 1 Nsutorumentoba full 12 there ░ C-beam disposed
in the front of the speaker 20 provided in Yatsuerufu 18 has been reflecting member:) 40 only
Kyoshu Shinano ~ - a reflector 44 to a suitable angle If properly adjusted with-, the directivity is
controlled by the 2 reflecting plate 44, so that it is direct or 7c + window.
It is reflected only once in the direction of the rear window crows and propagated to the square i,
so the 1st power-is a distorted reverberation sound, a beating sound, a humming sound that has
been reflected many times on the same glass surface etc.? It has a clear oldness without ?1? (it
has an excellent convex (6) sound effect. In addition, if the reflectors 44 provided on the front of
the speaker 20 provided on the door trim 14 or the quarter trim 16 have a power of 15 as the
reflectors 44 are appropriately adjusted, the directivity is 11 by the one reflector 44. Humancontrolled sound is transmitted directly to the car, so you can hear clear sound directly and have
excellent sound effects. In the above embodiment, the reflecting portion ? A ? 34 is provided
between the mounting node 30 of the speaker 2 o and the mounting member 10, but may be
internally fitted to the arrow 28 of the speaker 20 as shown in FIG. As shown in FIG. 9, the 9
reflection member 64 may be provided separately from the speaker 20, and may be internally
mounted in the opening 50 of the mounting surface and fixed together with the speaker 20 to
the mounting member 10 with a bolt and nut 52. The reflecting member 64 may be provided on
the side opposite to the speaker 20 in the hole 19 of the mounting member 10. In addition, the
instrument panel 12 facing the vehicle interior, the door trim 14. The speaker 20 may be
attached to the quarter trim 16 (7) or a member existing behind the rear shelf 18, and the
reflecting member 34 may be provided integrally with or separately from the speaker (in
addition, the reflecting member) 64 may be provided near the vehicle body such as the rear
window.
