サラウンド・サウンドシステム
[0001]
The present invention relates to a surround sound system, and in particular, to avoid interference
of cable resistance, the length of a signal line of a surround speaker can be greatly shortened,
and the surround of the interior of the room is not disturbed or damaged. -It relates to a sound
system.
[0002]
Many people are installing "home theater" at home, and are increasing.

In any "home theater", it is necessary to draw a pair of cables toward the rear left and right
corners and install surround speakers.
[0003]
A 5.1 channel (5.1 CH) speaker with all channels for left, center, light, left surround, light
surround and heavy bass has been recognized by consumers as a standard equipment of "home
theater", but Consumers are increasingly focusing on home decor. Therefore, the increasing
number of sound planners (sound-planners) is that when many consumers are trying to create a
home theater, how to make the interior of the home by the rear surround and the light surround
pull wire process behind He stated that he was most plagued by the problem of avoiding being
blocked or damaged.
[0004]
In addition, generally, in order to operate the speaker by the amplifier, a signal line or a speaker
line must be used between the amplifier and the speaker, but the used lengths of these signal
lines and the speaker line are related to the effect of the output sound quality. Not too long or too
short. Also, these signal lines and speaker lines are troublesome but must be used. If there is a
way to connect (heat) the speakers directly to the amplifier, the sound can be heard with better
sound effects than connections using expensive (several hundred thousand original) signal lines
or speaker lines. Because of this, wireless speakers were born in response to such circumstances,
but the only problem is that the price is too high.
[0005]
In short, if it is going to build 5.1 channel "home theater" by the method of pull wire, the pull
wire process of surround speakers may block or damage the interior of the home, and build the
same "home theater" from wireless speakers If you try, there is a problem that the price will be
too high.
[0006]
Therefore, how to balance the two, eliminating the need to pull cables towards the rear left and
right corners, and offering consumers the option to approach common level without increasing
the price. Is an important subject of the present invention.

The surround sound system of the present invention effectively adapts to a surround speaker
installed behind by sound reflection technology, and a pair of surround speakers to be installed
behind it is provided in front of the user, by reflection of sound waves. Can hear the output
sound from the rear, which eliminates the need to pull the cable further toward the rear left and
right corners, avoids damaging the interior of the home, and the cable length It's appropriate so
you don't have to think about complex cable resistance issues, and it's aimed to have a similar
effect to wireless speakers at a regular price without using expensive wireless speakers.
[0008]
In order to achieve the above object, the present invention provides a pair of front speakers
provided in the front and a front provided in the surround sound system provided in the front
and the rear of the user and capable of outputting directional sound waves. A pair of surround
speakers, a reflection member provided at the rear, which reflects directional sound waves from
the surround speakers to the user, electrically connected to all the speakers, and all audio signals
exceed A surround sound system comprising: a control unit for delaying the audio signal of the
unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS To describe the features of the
present invention and the technical contents thereof in more detail, specific embodiments of the
present invention will now be described in detail with reference to the accompanying drawings.
[0010]
As shown in FIG. 1, the present invention provides a surround sound system comprising at least
one control unit 6, a number of speakers and a pair of reflective members 7.
This generates surround sound, and the user 8 experiences the realistic sound of the home
theater brought about by the surround sound on the spot.
In this surround sound system, sound sources are provided in front of and behind the user 8 to
generate surround sound surrounding the user 8.

[0011]
As is well known, the most basic surround sound is a four channel surround sound system,
comprising a pair of front speakers and a pair of surround speakers.
In the 4.1 channel system, a subwoofer is additionally installed somewhere forward.
In a 5.1 channel system, furthermore, a center speaker is placed in front, preferably facing the
front of the user, to produce good 5.1 channel surround sound.
[0012]
As shown in the figure, the surround sound system of the present invention comprises a pair of
front speakers 2, a pair of surround speakers 3, a center speaker 4, a subwoofer 5, at least one
control unit 6, and a pair of reflections. And a member 7.
Among them, the pair of front speakers 2 are respectively installed in the front left and right
places, and the center speaker 4 is installed in the front, preferably facing the front of the user.
The subwoofer 5 may be installed anywhere in the front. The pair of surround speakers 3 is not
provided at the rear, but is specially provided at the front and is provided at the left and right.
The pair of surround speakers 3 are both directional speakers, and output directional sound
waves instead of ordinary scattered sound waves. The pair of reflecting members 7 are
respectively installed at the rear left and right places, receive directional sound waves from both
surround speakers 3 and reflect them to the user. The control unit 6 is electrically connected to
each of the speakers to transmit and output an audio signal to each of the speakers.
[0013]
When the user 8 is in the surround sound system of the present invention, the pair of surround
speakers 3 is installed in front of the user 8, but the pair of surround speakers 3 outputs the
directional sound waves. Since the directional sound waves are directed to the pair of reflecting
members 7 disposed behind the person's ear, not the user's ear, the user can not directly hear the
10-05-2019

directional sound waves output forward from the pair of surround speakers 3. The directional
sound waves are directed to the reflecting member 7, received by the reflecting member 7, and
then reflected so as to be audible to the user 8 in the form of scattered sound waves. In other
words, the sound output from the pair of surround speakers 3 newly installed in the front is the
same as the sound output can be generated in the rear by being reflected at the rear by the
reflection member 7, so the output from the rear Sounds like a voice.
[0014]
However, since the time (delay time) until the sound output from the surround speaker 3 reaches
the reflecting member 7 causes a delay phenomenon, the delay synchronized with a part of the
audio signals that all the audio signals exceed is generated. It is necessary to be given. When the
control unit 6 delays and then outputs the audio signal output from the front speaker 2, the
center speaker 4 and the subwoofer 5, synchronization with the audio signal output from the
surround speaker 3 is achieved, and 5.1 channels are obtained. The demand for surround sound
is achieved.
[0015]
In this way, in the surround sound system of the present invention, since the surround speaker 3
to be originally installed can be installed in the front, it is not necessary to pull the cable to the
rear left and right corners and the pull wire distance It can be greatly shortened.
[0016]
In addition, the delay control of the control unit 6 obtains the delay time to be controlled by
manually inputting the distance data corresponding to the above delay time (that is, the
separation distance between the surround speaker 3 and the reflecting member 7 corresponding
to each other). The delay time to be controlled can be obtained by automatically detecting the
distance data.
Also, the automatic detection may directly obtain the delay time to be controlled. For example, in
a state where a microphone is provided to the surround speaker 3 and the surround speaker 3
and the reflecting member 7 are made to face each other, the sound wave is reflected by the
reflecting member 7 from the time when the sound wave is emitted from the surround speaker 3
The above-mentioned delay time can be obtained by measuring the time until the signal is
10-05-2019
5
received and calculating the half time of the time.
[0017]
The control unit 6 may be in the form of a control case (as shown in the figure), and may be
outputted by the computer in the form of a computer (not shown) and may be subjected to delay
control or the like. Furthermore, it may be a control circuit (not shown), in which case the control
circuit is installed directly on any one speaker (for example, the center speaker 4).
[0018]
The reflecting member 7 is a reflecting plate capable of reflecting a sound wave, and the material
is not particularly limited as long as the material can reflect the sound wave.
[0019]
The present invention can achieve the following effects.
Since all conventional surround speakers need to be installed at the rear, the length of the pull
wire becomes extremely long, whereas the surround speaker of the present invention can be
provided at the front, even if it is provided at the front, The reflection of the sound makes it
possible for the user to hear the output sound from behind when he / she hears. And since it is
not necessary to pull the cable toward the rear left and right corners, it is possible to avoid
damaging the interior of the home, and since the cable length is appropriate, complex cable
resistance problems can be avoided. You don't have to think about it, and you don't have to use
expensive wireless speakers, you can get effects similar to wireless speakers at a regular price.
[0020]
As explained above, the surround sound system provided by the present invention can certainly
solve the serious drawbacks of the prior art, has a very high industrial value and can be
effectively enhanced. Filing applications in accordance with the law, as it fully meets the
requirements of the patent.
