BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
integrated speaker for 5.1 channel sound field reproduction.
2. Description of the Related Art Currently, to reproduce 5.1 channel sound field such as DVD
and digital high vision, it is necessary to place each independent speaker on the floor, which is
the world of mania and home It is difficult to bring it into the living room.
[Problems to be Solved by the Invention] In order to spread these playback devices, whose main
feature is 5.1 channel sound field such as DVD, BS digital high vision, etc., to the general
household, it is essential to bring them into the living room I will not let you.
In addition, it is necessary not to lose its powerful functions, to harmonize with a narrow living
room, and to take up no space. The present invention solves these.
SUMMARY OF THE INVENTION In order to reproduce a 5.1 channel sound field in a DVD or
digital broadcast, the present invention mounts a low range reproduction speaker toward the
lower floor surface, In addition, the left and right main speakers and the center speaker face
horizontally in the front direction, and by changing the position in the 90-degree direction, both
have a structure to suppress interference with other speakers due to the vibration generated by
the bass speaker. It relates to an integrated speaker for 5.1 channel sound field reproduction.
DETAILED DESCRIPTION OF THE INVENTION The solution is divided into two.
One is how to make it compact without losing its function. To play 5.1 channels, you will need
left and right main speakers, a center speaker, two rear rear speakers, a woofer for bass, and at
least six speakers. Of these speakers, four speakers are integrated except the rear rear speaker.
A large screen plasma display is placed at the center of the built-in frame, main speakers on the
left and right, and a center speaker at the bottom of the center of the screen. The large bass
speaker is mounted on the bottom of the floor. The low range is this direction because it does not
depend on the directivity from the sound source generation axis of the speaker. In addition, a
strong reinforcing material is fixed between the speaker mounting surface and the board serving
as a pedestal of the plasma speaker on the back side of the speaker mounting surface.
The other one is harmony when installed in the living room. In order to fully watch BS digital
broadcasting, DVD, etc., equipment of 5-channel amplifier, DVD, VTR, BS tuner, plasma display is
required. It is necessary to organize and store all of these devices in a compact manner.
By attaching two rear speakers to the back wall of the living room, you can enjoy the contents of
almost DVD software and BS digital in a 5.1 channel sound field. Also, in the future, BS digital
high-definition television will be used as a shopping tool for its convincing power. Fine, highdefinition images and more realistic sound fields are essential.
Hereinafter, the description will be made with reference to the drawings. FIG. 1 shows a mounted
front view. FIG. 2 shows the side view. FIG. 3: is a front view which shows the state which
removed the front glass door of the lower accommodating part, the speaker, and the makeup net.
FIG. 4 shows its bottom view. FIG. 5 is a cross-sectional view seen from the top of the central
portion, and FIG. 6 is a cross-sectional view seen from the side.
Reference numeral 1 denotes a plasma display, which is at the upper front. Reference numerals 2
and 3 denote left and right main speakers, which are located on the left and right of the plasma
display. A center speaker 4 is provided at the center. 5 is a woofer for bass and is provided on
the bottom, facing the floor. The reference numeral 6 denotes a VTR, 7 denotes a DVD, 8 denotes
a BS tuner, and 9 denotes a 5-channel amplifier, which are conveniently stored on the left and
right. The reference numeral 10 denotes an AV sector, and 11 denotes an amplifier for driving a
bass speaker. Main speakers are provided on the left and right.
Reference numeral 12 denotes a reinforcing material for fixing between the bass speaker
mounting plate and its back plate. A reference numeral 13 denotes a separator for the bass
speaker and the center speaker, which is provided on the back of the center speaker. The
reference numeral 14 indicates the vibration direction, and the center speaker vibrates
horizontally backward and upward for bass. 15 is a duct for phase inversion.
In this integrated speaker, the vibration amount of the mounting plate is the largest for the bass
speaker, so the mounting direction with the other three speakers is changed by 90 degrees, and
mutual interference is minimized. I can hold it down.
Industrial Applicability The present invention is an effective means for bringing a 5.1 channel
sound field into a living room, and even in a narrow living room, its effect can be enhanced.
For example, in a television broadcast program, standing in the dusk of Kyoto, the sound of a bell
heard from the front from behind will be in the position for a moment.
It can be a place of family sharing from the world of mania.
