[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-board karaoke system and, more particularly, to an improvement of a remote control device thereof.

[0002]

2. Description of the Related Art Conventionally, a karaoke system for a vehicle, particularly a passenger car, has a karaoke system body including a display, a microphone, and a speaker. Lyrics are displayed on the display in synchronization with karaoke music output from the speaker. Configuration. Such a display is generally provided on a front panel between a driver's seat and a passenger seat from the viewpoint of operability and visibility.

A technique for remotely controlling a karaoke system body to adjust the volume or the like is disclosed in, for example, Japanese Patent Laid-Open No. 6-290.
No. 394, etc.

[0004]

As described above, when the display is provided on the front panel between the driver's seat and the passenger's seat, a person who has arrived at the rear seat can take a considerable amount of time from the rear seat to the display. May not be read depending on the size of the characters of the lyrics displayed on the display.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has a karaoke system having a speaker for outputting music and a first display for displaying first lyrics. A remote control device having a main body and a second display, wherein the second lyrics are displayed on the second display.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Music output from a speaker of the karaoke system and lyrics displayed on a first display are formed from music data and character data, respectively. These music data and character data can be captured as so-called communication karaoke data from outside the vehicle via a mobile communication device such as a mobile phone or a car phone. Further, the music data and the character data may be recorded on an in-vehicle recording medium such as a CD, a ROM, and a DVD, and may be used by being reproduced by a predetermined reproducing device. An image (moving image or still image) can be displayed on the first display simultaneously with the lyrics. This image is formed from image data transmitted from the outside as communication karaoke data or image data recorded on a vehicle-mounted recording medium.

[0007] As the speaker, an in-vehicle audio speaker can be used. Of course, a speaker dedicated to the karaoke system may be separately provided. The first display only needs to be able to display at least lyrics. In consideration of displaying an image, it is preferable to use a liquid crystal or a CRT.

As the microphone of the karaoke system, a general microphone such as a hand-free microphone or a wireless microphone can be used. A wireless microphone can be incorporated in the remote control device. In this case, the sound collected by the microphone is converted into an electric signal, and the electric signal is input to a well-known transmitting / receiving device of a remote control device and transmitted therefrom, for example, as an infrared signal. The infrared signal transmitting / receiving device is incorporated in the karaoke system main body, and the received infrared signal is converted into an electric signal, mixed with a signal based on music data, and output from a speaker.

For synchronizing music and lyrics, for example, a series of music data strings and character data strings incorporating data serving as a reference for synchronization are processed using a microcomputer that operates with a known program for synchronizing. This is achieved by: Based on such processing, the respective drivers (control devices) of the speaker and the first display are controlled so as to synchronize music and lyrics. Synchronization of images with music and lyrics is similarly performed.

[0010] The form of synchronization between music and lyrics is not particularly limited. For example, the color of the lyrics (telop) displayed on the screen may change from the end as the music progresses. The display of the lyrics may not be synchronized with the song as long as the lyrics can be visually recognized by the user and assist in singing along with the song. For example, there is a case where all of the lyrics are displayed on the display at once.

A general-purpose switch can be used as the operation switch of the karaoke system main body. A transparent electrode is provided on the first display and can be used as a touch panel type switch.

A transmitting / receiving device for communicating with the remote control device is provided in the karaoke system main body. Communication between the main body and the remote control device is performed using light, particularly, infrared light or radio waves. For the former, see Nikkei Electronics (1997.2.
10), No. 682, pp. 175-181. For the latter, see page 2-3 of JP-A-57-20057.

It is assumed that the second display of the remote control device can display at least lyrics. More preferably, an image can be displayed. Preferably, the lyrics displayed on the second display are synchronized with the music. This synchronization uses the above-mentioned microcomputer of the karaoke system itself,
This is realized in the same manner as in the case of the first display. Preferably, the form of synchronization for music is unified on the first and second displays. In this case, it can be said that the display of the lyrics on the second display is synchronized with the display of the lyrics on the first display.

The size of the second display is limited because it is provided in the remote control device. Also, the second display is seen by the user at a closer distance than the first. Therefore, the lyrics displayed on the first display and the lyrics displayed on the second display can have different display forms. For example, all the lyrics are displayed on the first display (in this case,
The lyrics are not synchronized with the music), and the second display can display the lyrics for each movement due to the limitation of the screen space (in this case, the lyrics are synchronized with the music). The lyrics displayed on the second display are also formed using the character data.
