DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound source for a speaker such as an actor or a singer in a theater or a hall when the speaker performs while moving, or when a different instrument is performed alone in an orchestra. The present invention relates to a sound image localization system in which a sound image formed by a speaker is made coincident with the position of the sound source, and the position of those sound sources can be enjoyed while the audience can easily confirm the position.

[0002]

2. Description of the Related Art In a case where the position of a sound source is changed as described above, especially in a theater such as a musical, a kabuki, or a stage drama, the audience enjoys watching the operation of the performer. It is desirable to be able to determine whether there is a sound source in the direction.

Therefore, conventionally, a microphone, a speaker, and a control unit are connected to a sound image localization unit, and a sound image localization input device is connected to the control unit. , The sound manager inputs the position by manipulating the switch for selecting the sound image localization position by the sound image localization input device, and delays the output timing from each speaker according to the delay data and the volume data according to the input position. I was trying to make it.

[0004] In some theaters in which the actions of the actors are defined based on a script, a sound image localization position corresponding to a scene is automatically input in advance at points according to the script.

[0005]

However, in the case of the former conventional example as described above, there is a disadvantage that the operation for inputting the sound image localization position is troublesome, and that an input error occurs. On the other hand, in the case of the latter conventional example, there is a drawback that a large deviation occurs when the actor is wrong.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a sound image localization system that can easily and accurately perform sound image localization.

[0007]

According to the sound image localization system of the present invention, in order to achieve the above-mentioned object, a plurality of speakers are provided on a stage at predetermined intervals in a width direction of the stage, and a plurality of speakers are provided on the stage. A sound source position detection sensor for detecting the position of the sound source, a distance calculation means for calculating a distance between each of the speakers and the sound source based on the position of the sound source detected by the sound source position detection sensor; And a transmission order setting means for outputting a speaker closer to the sound source on the basis of the detected distance, so that the output is performed earlier.

[0008]

According to the configuration of the sound image localization system of the present invention, the relative positional relationship between a sound source such as an actor and a speaker is automatically determined, and the sound is transmitted in order from the speaker whose distance is short, and the direction of the sound source is determined. Can be understood by the audience.

[0009]

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an overall schematic diagram showing an embodiment of a sound image localization system according to the present invention. First, second, and third speakers are provided at three positions on a left side, a center, and a right side of a front surface of a stage 1. 2a, 2b, and 2c are provided, and the first, second, and third speakers 2a, 2b, and 2c are respectively provided with first, second, and third sensors as sound source position detection sensors.
Receivers 3a, 3b, 3c.

The first, second and third receivers 3a, 3a,
A signal received from each of 3b and 3c and a signal transmitted from the microphone 4 attached to the speaker H as a sound source are input to the computer 5. As shown in the block diagram of FIG. 2, the computer 5 includes a distance calculating unit 6 and a transmission order setting unit 7.

The distance calculating means 6 uses the received signals from the first, second and third receivers 3a, 3b, 3c and the transmitted signal from the microphone 4 to determine when the signal is transmitted from the microphone 4 and when the first and second signals are received. Second and third receivers 3
The distance between the microphone 4 and each of the first, second, and third receivers 3a, 3b, 3c, that is, the distance between the speaker H and the first, Second and third speakers 2a, 2b, 2c
Is calculated.

The transmission ranking means 7 includes a distance calculation means 6
Are compared with each other, and the first, second and third receivers 3a, 3b,
3c is ranked in any order, and based on the ranking, the first, second and third speakers 2a and 2c are ranked.
The activation signals are output in order from b and 2c in the order closer to the microphone 4.

With the above configuration, when the speaker H such as an actor or a singer moves on the stage 1, the position is detected, and the sound through the microphone 4 is preceded by the speaker near the position. When the speaker H is generated, the audience can easily confirm the position of the speaker H and enjoy the performance of the speaker H.

When the distance calculating means 6 determines that the distances are equidistant from the first and second speakers 2a and 2b, for example, the first and second speakers 2a and 2b
A start signal is output to 2b at the same time.

In the above embodiment, the first, second and third speakers 2a, 2b and 2c are respectively provided with first, second and third receivers 3a, 3b and 3c, and the microphone 4 and the first , The second and third speakers 2a, 2b, 2
The distance to each of the speakers H is calculated to detect the position of the speaker H. For example, the first, second, and third receivers 3a, 3b, and 3c are provided above the stage 1, for example. You may do it.

The present invention can be applied to a case where a plurality of speakers are provided on the stage 1, that is, two or four or more speakers.

[0018]

As described above, according to the sound image localization system of the present invention, the relative positional relationship between a sound source such as an actor and a speaker is automatically determined, and the relative position is determined in the order from the speaker having the shorter distance. A sound image localization system can be provided which can automatically input a sound image localization position according to the actual sound source position because the sound source is made to be transmitted and the audience can know the direction of the sound source, and the sound image localization can be performed easily and accurately. Was.
