And a transmission unit. The information for identifying the speaker may be, for example, an IP address assigned to each of the speaker devices 10, and is not limited to this, and any information that identifies the speaker device 10 may be used. It may be.

  Next, a specific example of the position detection unit of the speaker device 10 will be described below with reference to FIGS. 9 to 12. In FIG. 9, the position detection unit 90 includes a light emitting / receiving unit 91 provided on the moving body 60 side and a bar code 92 provided on the power supply rail 50 side. The bar codes 92 are bar codes 92a, 92b,... 92n indicating different code information, and the bar codes are arranged at predetermined intervals on the inner surface of the power supply rail 50 facing the light emitting / receiving portion 91 as shown in FIG. Affixed to. In the case of this embodiment, it is arranged below the power supply terminal 54.

  In the position detection unit 90, the light receiving / emitting unit 91 reads the barcode, and detects the position of the moving body 60 on the power supply rail 50 based on the read barcode information. For this purpose, the correspondence relationship between the information indicated by the barcode and the position on the power supply rail 50 may be stored in the storage unit 22 of the management device 20 or the like. In the position detection unit 90, the bar code 92 attached at predetermined intervals is read by the light emitting / receiving unit 91 to intermittently detect the position of the moving body 60 in the extending direction of the power supply rail 50. become.

The configuration of the position detection means is not limited to the configuration of the light emitting / receiving unit 91 and the barcode 92, and various configurations are possible. Some examples are listed below.
(I) Optical sensor Transmission type sensor As shown in FIG. 11, a photo interrupter arranged so that the light emitting portion 93A and the light receiving portion 93B face each other is used as a detecting portion 93, and the light emitting portion 93A and the light receiving portion 93B A shutter 94 that moves relatively is disposed between them. Here, the detection unit may be provided on the moving body 60 side, the shutter 94 may be provided on the power supply rail 50, the shutter 94 may be provided on the moving body 60 side, and the detection unit may be provided on the power supply rail 50. What is necessary is just to be able to detect mutual relative movement.

As the configuration of the shutter 94, FIGS. 12A, 12B, and 12C are conceivable.
Similar to the position detection unit 90 described above, when it is desired to detect the position of the moving body 60 at a predetermined position, as shown in FIG. Are formed with through holes 94a, 94a,. At this time, the diameters of the insertion holes 94a are formed so as to be gradually different so that the diameter of light emitted from the light emitting portion 93A (light emission diameter) is larger than that of the maximum diameter insertion hole 94a.
Further, as shown in FIG. 12B, a slit 94b is formed in the shutter 94B. The slit 94b is formed so that its width dimension gradually decreases from one side to the other side in the extending direction of the shutter 94B, and the diameter of light emitted from the light emitting portion 93A is larger than the maximum width dimension. To do.
Further, as shown in FIG. 12C, the outer shape of the shutter 94C is gradually inclined from one side to the other in the extending direction, and the diameter of light emitted from the light emitting portion is larger than the maximum width of the shutter 94C. To be the same or larger.

As described above, in the structure of the shutter 94 </ b> A in FIG. 12A, it is possible to detect that the moving body 60 is present at a predetermined position of the power supply rail 50, similarly to the position detection unit 90 described above.
In the structure of the shutters 94B and 94C in FIGS. 12B and 12C, the position of the power supply rail 50 with respect to the value of the received signal from the light receiving unit 93A is stored in advance in the storage unit 22 or the like of the management device 20. In addition, the position of the moving body 60 relative to the power supply rail 50 can be detected by calculation from the magnitude of the received signal at the light receiving unit 93B. In this case, while the previous position detection unit 90 performs intermittent position detection, a continuous reception signal is generated by using the optical sensor having the shutter structure shown in FIGS. As a result, the position of the moving body 60 is continuously detected.

  The optical sensor is not limited to a transmissive sensor, and may be a reflective sensor. In this case, as shown in FIG. 13, the light emitting unit 93 </ b> C and the light receiving unit 93 </ b> D have a detection unit 93 ′ and a reflection plate 94 </ b> D that reflects light from the light emitting unit. The shape of the reflecting plate 94D is formed into a shape in which the amount of reflection changes with respect to the extending direction of the portion where the reflecting plate is attached. For example, the slit shape shown in FIG. 12B or the shutter shape shown in FIG. Furthermore, when it is desired to intermittently detect the position of the moving body 60, a reflector having a different reflection amount is attached to a predetermined position in the extension direction, and when it is desired to continuously detect the position of the moving body 60, the extension is performed. What is necessary is just to stick the reflector of the shape where the amount of reflections changes gradually with respect to a direction.

In this case, a semiconductor Hall element, a semiconductor magnetoresistive element, or the like is used as the detection unit, and the detection target unit is a magnetized part applied to the part of the magnetic material. The magnetized part to be detected is magnetized at predetermined intervals so that the magnetic field in the magnetized part is different. Thereby, based on the detection signal from a detection part, the position of the moving body 60 in the extending | stretching direction of the electric power feeding rail 50 is detected intermittently. In addition, the magnetized part is not formed at predetermined intervals, but the magnetic field of the magnetized part can be continuously detected from the detector by magnetizing the magnetic field so that it gradually changes in the extension direction. The position of the moving body 60 in the extending direction of the power supply rail 50 is continuously detected.

(Iii) Other sensors The configuration of the position detection means is not limited to the bar code, the optical sensor, the magnetic sensor, and the like. It is not limited to these. In the above example, the case where the detected part such as the shutter is changed with respect to one sensor has been described. The position may be detected by assuming that the moving body 60 is in a portion where the light from the light emitting unit is shielded by the moving body.

  Next, an example of the operation in this modification will be described below. When the speaker device 10 is installed on the power supply rail 50, the position detection unit of the speaker device 10 reads position information that is closest to the installed position, and uses the read position information as speaker position information together with the ID of the speaker device 10.

And the control part 21 shows the position of the speaker apparatus 10 shown in the arrangement | positioning figure which shows the arrangement | positioning state of the electric power feeding rail 50 based on the electric power feeding rail arrangement | positioning information in the arrangement | positioning information storage area, and the received speaker position information, and this arrangement | positioning figure. Display information to be displayed is generated, and the generated display information is output to the display unit 23. Based on the display information supplied from the control unit 21, the display unit 23 displays an arrangement diagram showing the arrangement state of the power supply rails 50 and an image showing the position of the speaker device 10 shown in the arrangement diagram. As a result, an image showing the layout of the speaker device 10 is displayed on the display unit 23. The user can check the layout of the speaker device 10 by looking at the screen displayed on the display unit 23.

According to this aspect, the control unit 21 calculates the channel type to be distributed to each speaker device 10 simply by moving the speaker device 10 on the power supply rail 50 by the user.
According to this aspect, the control unit 21 specifies the position of each speaker device 10 based on a control signal (a pair of an IP address and position information) supplied from the speaker device 10, so that the user can operate The layout image representing the position of the speaker device 10 is displayed on the display unit 23 without operating the unit 24.
