DESCRIPTION JP2005045750
PROBLEM TO BE SOLVED: To provide a device capable of obtaining a three-dimensional sound
effect in an audio device such as a television and a movie. SOLUTION: Sounds in four directions
recorded by four microphones of upper left 3, upper right 4, lower left 5, lower lower 6 are
upper left 13, upper right 14, lower left 15, lower lower 16 4 It is possible to obtain a threedimensional sound effect by producing sound with a speaker at a point. [Selected figure] Figure 1
Acoustic device such as television and movie etc. Detailed description of the invention
[0001]
The present invention makes it possible to obtain a three-dimensional sound effect by producing
sound from four directions, up and down and left and right, in a sound system of a movie, a
television, a video game, and a personal computer.
[0002]
In audio equipment for movies and televisions, sound sources are input with microphones in the
left and right directions, and are output using speakers in the left and right directions.
For example, if an airplane is turning in the air from right to left in the direction, the sound of the
airplane is heard moving from right to left, then from left to right, and further from right to left.
In this, the airplane sounds like it's going back and forth acoustically, even though it's flipping

from right to left. Furthermore, even when a bird is singing on a tall tree, it sounds like the crying
is singing at the height of a person's height rather than on a tree.
Problems that the Invention is to Solve
[0003]
Therefore, the acoustic device in the left and right directions can not express the acoustic effect
in the height direction.
Means to solve the problem
[0004]
According to the present invention, microphones are attached to the television camera 2 at four
locations: upper left 3, upper right 4, lower left 5 and lower right 6 so that a three-dimensional
sound effect can be obtained.
These four types of sounds are adjusted by the broadcast facility 7, transmitted by the antenna 8,
and received by the antenna 9 of each home. In each home, the recording and reproduction deck
10 records the sound of up and down and left and right and reproduces it, or directly attached to
the television 12 by the speakers of upper left 13, upper right 14, lower left 15 and lower right
16 It is possible to output sounds in four directions. Also in the case of a movie, it is possible to
obtain similar three-dimensional sound effects by speakers arranged at the top, bottom, left, and
right of the screen.
[0005]
As shown in FIG. 1, if four types of sound input by four microphones at the top, bottom, left, and
right are transmitted by four types of radio waves, and they are received by a television with four
speakers at the top, bottom, left, and right It is possible to obtain three-dimensional sound effects
of up, down, left and right. In addition, it is possible to obtain the same effect by recording and
reproducing four kinds of sounds on the recording and reproduction deck, respectively.
Furthermore, even in game machines and personal computers, similar effects can be obtained by

using software corresponding to the four types of sounds in the upper, lower, left, and right.
Effect of the invention
[0006]
The present invention makes it possible to obtain a three-dimensional sound effect closer to
actuality by outputting four types of sounds input to the four microphones at the upper and
lower, left and right, by the four speakers at the upper and lower, left and right It is a thing.
