A function for identifying the position of the person based on the detection signal of the person sensor, a function for driving and controlling the driving means to direct the output direction of the voice output means to the position of the person, and voice information to the voice output means. A control device 2 that is a control means having a function to output, an amplification device 3 that is an amplification means that adjusts the volume of audio information broadcast from the audio output means, and a drive device that is a drive means that switches the output direction of the audio output device 4 and a speaker device 5 which is sound output means having directivity and outputting sound information.

The target person detection sensors 1 are installed at a plurality of locations within the installation location of the system, and detect the presence of a person.
The control device 2 analyzes the information from the target person detection sensor 1 to specify the position of the person and determine the sound information to be transmitted to the person.
The amplification device 3 amplifies the transmission information in accordance with the control command transmitted from the control device 2.
The drive device 4 controls the direction of the speaker in accordance with a control command from the control device 2.
The speaker device 5 is a highly directional speaker device that broadcasts an audio signal transmitted from the amplifying device 3.

In addition, as a place where this system is installed, it is a company, a commercial facility, a public facility, etc., and can be installed not only indoors but also outdoors.
The broadcast area refers to a range in which audio information output from the speaker device 5 of this system reaches.
Further, if audio information can be transmitted to a farther person by using the speaker device 5 having higher directivity, the broadcast area of the broadcast area automatic selection broadcast system of the present invention is set to several tens meters to several hundred meters. Can be expanded to orders or more.

In the broadcast area automatic selection broadcasting system according to Embodiment 1 of the present invention, when a person who wants to transmit specific information by broadcasting enters the broadcasting area of this system, a plurality of target person detection sensors 1 (for example, ultrasonic sensors) are installed. , Infrared rays, laser, etc.), the position of a person who wants to transmit specific information is detected by broadcasting, and the detected information is transmitted to the control device 2.
Here, the target person detection sensor 1 can be composed of, for example, an ultrasonic sensor, an infrared sensor, or a sensor using laser light.

Based on the information detected by the target person detection sensor 1, the control device 2 specifies the position of the target person to which information is to be transmitted, transmits the audio information to be transmitted to the person to the amplifying apparatus 3, and The driving amount of the speaker device 5 according to the position condition is transmitted to the driving device 4.
The amplifying device 3 amplifies and transmits an audio signal representing audio information to be transmitted to the speaker device 5.
The driving device 4 changes the direction of the speaker device 5 in the direction in which information is desired to be broadcast (that is, the direction in which the target person is to transmit information) based on the driving amount transmitted from the control device 2.
The speaker device 5 broadcasts the audio signal transmitted from the amplifying device 3. Information broadcast from the speaker device 5 is transmitted to the target person.

  As described above, according to the broadcast area automatic selection broadcasting system according to Embodiment 1 of the present invention, the position of the target person to which information is transmitted is specified, and the specific information is broadcast with the speaker device 5 directed toward the target person. Therefore, it is possible to cope with a change or increase in a place where information to be transmitted is broadcast without adding or moving a broadcasting system such as a speaker device or an amplification device.

  In addition, although the case where the number of the speaker apparatus 5 was demonstrated was demonstrated above, if the number of the speaker apparatuses 5 is increased, a broadcast area can be expanded further. Even in that case, the direction of each speaker device 5 is driven by the drive device 4, so that the number of speaker devices 5 can be greatly reduced even in a broadcast area having the same area as the conventional broadcast system.

In addition, the control device 2 not only specifies the position of the target person based on the detection information of the target person detection sensor 1, but also the position of each of the target person detection sensors 1 installed in the broadcast area and the speaker device 5. The distance between the position and the position may be stored in the control device 2 in advance as data, and the amplifying device 3 may be configured to amplify the audio information as the transmission information according to the distance from the speaker device 5 to the target person. Good.
Also, the broadcast area can be divided into several small areas according to the position of the target person detection sensor 1, and different information can be broadcast in each small area. In this case, a small area may be switched according to a time zone, or information set for the small area may be broadcast to a small area where a person is detected within the same time zone.
In the above description, a mobile phone that broadcasts audio information to a person has been described. However, it is also possible to configure to broadcast sound information to animals other than humans, other living things, and the like. Such forms are also included in the scope of the claims.
