Abstract

PURPOSE:To prevent sound from leaking outside by installing a regular speaker reproducing the sound of an audio equipment and the directional speaker of a sharp directivity and providing a switch which selects the speakers and changes over them within doors. CONSTITUTION:For enjoying the sound of the AV Equipment 1, sound from the surround speaker is usually listened to. Then, it is changed over to the directional speaker 3 at night, etc. Satisfactory sound can be listened to in the range of oblique lines in a figuar if the speaker is changed over to the directional speaker 3. But, sound cannot well be listened to beyond the ldiagonal lines. Namely, sound can be prevented from leaking outside and a nuisance owing to noise is prevented. Then, the sound of the AV equipment 1 can be enjoyed at any time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an indoor acoustic system equipped with directional speakers.

[Conventional technology]

AV equipment installed indoors, such as in homes, is equipped with ordinary speakers with broad directivity. There are various types of speakers depending on the system, and they can be installed on the ceiling or wall of a room.

[Problem to be solved by the invention] By the way, in conventional sound systems, when the volume is high, the sound from the speakers may leak into neighboring areas such as outdoors, and the problem is that the noise can cause a nuisance, especially at night. .

This invention was made by focusing on these problems, and it allows Availability to be used at any time without causing any nuisance due to noise.
The purpose is to obtain an indoor gFJ system that allows you to hear the sound of the device.

[Means to solve the problem]

The indoor sound system of the present invention is equipped with normal speakers for reproducing audio from audio equipment and directional speakers with sharp directivity indoors, and a switch for selecting and switching between these speakers. .

(Function) In the indoor sound system of the present invention, a directional speaker with sharp directivity is provided, and when switched to this directional speaker, sound is prevented from leaking outside.

〔Example〕

FIG. 1 is a block diagram showing the basic configuration of an audio system according to the present invention. In the figure, l is an AV device (audio device), 2.3 is a normal surround speaker and a sharp directional speaker that reproduces the audio of this AV device 1, and 4 is a speaker 2.3 selected. This is a switch that switches the switch.

FIG. 2 shows a specific example of the configuration of the above system, and shows the arrangement as seen from above the room. In the figure,
5.6 is a television screen and speakers. Moreover, FIG. 3 is a diagram showing the arrangement relationship seen from the side of the room. As shown in the figure, the television speakers 6 are installed on the floor of the room, and the surround speakers 2 and directional speakers 3 are installed on the ceiling of the room.

In the acoustic system configured in this way, the AV equipment 1
When enjoying the sound of the user, the user usually listens to the sound from the surround speakers 2, but at night, the user switches to the directional speakers 3. When switching to this directional speaker 3, the third
Good audio can be heard within the shaded area in the diagram, but not well heard outside the shaded area. In other words, the sound can be prevented from leaking outside, and the noise will not cause any nuisance.
The audio of the AV equipment 1 can be enjoyed at any time.

Here, the above-mentioned directional speaker 3 and switching device 4 can be installed and wired when a new house is built, etc., so that the AV
It is possible to easily connect the device 1 when installing it. Also,
Although the directional speakers 3 are installed on both the left and right sides of the ceiling surface in the embodiment, they may be installed at appropriate positions depending on the floor plan of the room.

〔Effect of the invention〕

As described above, according to the present invention, a directional speaker is installed and can be switched to the directional speaker as necessary, thereby preventing audio from leaking outside the center and causing a nuisance due to noise. This has the effect of allowing you to listen to the audio from devices A and V at any time without having to worry about it.
