DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a diagram showing a device configuration of a karaoke apparatus according to an embodiment of the present invention. The karaoke apparatus includes a main body 1, a voice adapter 2, an amplifier 3, a DVD changer 4, a monitor 5, and a stereo speaker (not shown). Also, as part of the karaoke device, a singing microphone and an infrared remote control device (not shown) are provided separately. The singing microphone transmits a singing voice signal to the amplifier 3 using a VHF FM signal. The infrared remote control device transmits a code-modulated infrared signal to the main body 1. The main body 1, the voice adapter 2, the amplifier 3, and the DVD changer 4 are configured to have the same width and depth and are stored vertically in the rack 10.
[0007]
The main body 1 has a performance function for generating a karaoke performance sound based on music data, a music selection reservation function for receiving a request from a user, a video processing function for synthesizing a superimpose of lyrics on a background video reproduced by a DVD changer 4, etc. And controls the entire karaoke apparatus.
[0008]
The voice adapter 2 is in charge of a voice processing function such as correcting a pitch deviation of the singer's singing or adding a harmony voice to the singer's singing, and the operation is controlled from the karaoke apparatus body 1. And receive data such as harmony melody data. In addition, the singing voice signal is received from the amplifier 3, and the processed singing voice signal and the harmony voice signal are returned to the amplifier 3.
[0009]
The amplifier 3 receives a singing voice from a singing microphone (not shown), receives a karaoke performance sound signal from the karaoke apparatus main body 1, receives a harmony voice signal from the voice adapter 2, mixes them, and outputs them to a speaker. The amplifier 3 and the speaker may be connected by a cord or may be transmitted by an FM signal. When transmitting by FM signal, the main amplifier which drives a speaker is built in each speaker side.
[0010]
The DVD changer 4 reproduces the background video and reads out the music data of the standard music written on the music data disk and transmits it to the karaoke apparatus body 1. Although the moving image recorded on the DVD is MPEG-compressed, the MPEG decoder may be built in the DVD changer 4 or may be provided in the karaoke apparatus main body 1. When the MPEG decoder is built in the DVD changer 4, the reproduced analog video signal is transmitted to the karaoke apparatus body 1. When the MPEG decoder is provided in the karaoke apparatus main body 1, the DVD changer 4 reads the data and transmits it to the karaoke apparatus main body as it is, and the karaoke apparatus main body 1 decodes this data and reproduces the video signal.
The monitor 5 receives the video signal from the karaoke apparatus body 1 and displays it on the CRT.
[0011]
FIG. 2 is a view showing the back configuration of the karaoke apparatus and the configuration of the back plate of the rack 10. In FIG. 2A, five rails 11 a to 11 e are formed on the back plate 11 of the rack 10. The rails 11a to 11e are formed in a U-shaped cross section (see FIG. 3), and optical fibers 12a to 12e are laid in each rail. The optical fiber 12 is a single-core soft resin fiber, and can be deformed by pressing from the side surface to cause transmission light leakage. Moreover, both ends of the optical fibers 12a to 12e are capped to prevent the intrusion of ambient light.
[0012]
Further, as shown in FIG. 5B, infrared input / output terminals 13 are provided on the back surface of each device of the karaoke apparatus so as to project at corresponding positions. As shown in FIG. 3, the infrared input / output terminal 13 is composed of a hard fiber tip that is in pressure contact with the side surface of the optical fiber 11 and deforms the soft optical fiber 12 by pressure contact. cause transmission leakage of the laser light into the fiber, can be or capture Dari sent a laser light signal from the input terminal 13 to the optical fiber 12, the optical signal being transmitted through the optical fiber 12. A data transmission / reception interface of each device is connected to the input / output terminal 13. As the interface, an IEEE 1394 or USB interface adapted to the optical fiber transmission may be used.
[0013]
An infrared input / output terminal 13 (13-1a, 13-1b, 13-1c, 13-1d) is provided on the back surface of the karaoke apparatus body 1 at a position facing the optical fibers 12a, 12b, 12c, 12d. . Further, on the back surface of the voice adapter 2, infrared input / output terminals 13 (13-2a, 13-2e) are provided at positions facing the optical fibers 11a and 12e. Thereby, the karaoke apparatus main body 1 and the voice adapter 2 perform transmission / reception of a control signal and data via the optical fiber 12a.
[0014]
In addition, an infrared input / output terminal 13 (13-3b, 13-3e) is provided on the back surface of the amplifier 3 at a position facing the optical fibers 12b and 12e. Thereby, the karaoke apparatus main body 1 and the amplifier 3 transmit / receive a control signal and a karaoke performance sound via the optical fiber 12b. Further, the voice adapter 2 and the amplifier 3 transmit and receive audio signals via the optical fiber 12e.
[0015]
On the back surface of the DVD changer 4, an infrared input / output terminal 13 (13-4c) is provided at a position facing the optical fiber 12c. As a result, the karaoke apparatus body 1 and the DVD changer 4 transmit / receive video signals (MPEG data) and control signals via the optical fiber 12c.
[0016]
An infrared input / output terminal 13 (13-5d) is provided on the back surface of the monitor 5 at a position facing the optical fiber 12d. Thereby, the monitor 5 receives a video signal from the karaoke apparatus main body 1 through the optical fiber 12d. This video signal is an analog signal.
[0017]
Thus, only accommodates various devices in the rack 10, the infrared input and output terminals 13 are pressed against the optical fiber 12, for allowing data transmission through the optical fiber is easy to install, each device Even if they are stacked in any order and stored in a rack, they are connected, so the degree of freedom is high.
[0018]
In the above embodiment, a plurality of optical fibers, each optical fiber is to be connected to equipment in a one-to-one, the data in the LAN system to connect all devices on a single optical fiber Transmission may be performed. In this case, only the transmission of the video signal may be performed on a separate line, or the video signal may be transmitted in packets using an extremely high-speed transmission protocol.
[0019]
It is also possible to perform data transmission wirelessly without using a cable. An infrared signal may be applied to the rear surface of the rack, and reflected light from the rear surface of the rack may be received by another device to transmit data. By changing the modulation frequency for each device, data transmission can be performed without interference.
[0020]
In the above embodiment, the data transmission method between the devices has been described. However, the transmission method between the infrared remote control device and the karaoke device main body 1 is also performed by the IrDA protocol, so that a song request is made from a so-called mobile terminal having an IrDA interface. Will be able to. Since the mobile terminal has various information processing functions, it is possible to program a plurality of song numbers in advance in the order of performance and transmit them to the karaoke apparatus body 1 at once.
[0021]
【The invention's effect】
As described above, according to the present invention, since the connection to the optical fiber line as the transmission line is completed only by housing the plurality of devices constituting the karaoke apparatus in the rack, the connection becomes extremely easy, and the rack Since the stacking order is arbitrary, the degree of freedom is high.
