Definitions

  • the present invention relates a portable wireless accompaniment apparatus, and more particularly to a wireless accompaniment apparatus in which all functions of the accompaniment apparatus are included in the body of a microphone so that an individual external apparatus except the microphone is not required to transmit lyrics, accompanying sound (background sound) and the like to a television receiver or a radio receiver in a wireless manner.
  • a conventional accompaniment apparatus in general, comprises a body of the apparatus and a microphone.
  • the microphone is, in a wired or wireless manner, connected to the body of the apparatus.
  • the body of the apparatus is connected to a display apparatus through a connection cable in a wired manner.
  • the body of the apparatus includes a storage medium, such as an optical disk.
  • the storage medium stores accompanying sound data and lyrics data for each tune. Data read from the storage medium and corresponding to a selected tune is, together with a vocal sound input through the microphone, transmitted from the body of the apparatus to the display device.
  • the caption is displayed on the display apparatus, and the vocal sound with the accompanying sound is transmitted from a loudspeaker.
  • a "karaoke" machine must deal with a plurality of tunes and, thus, has a necessity of providing a storage medium having a large capacity. Therefore, the size of the body of the apparatus is in a trend of being enlarged. The enlargement of the size of the apparatus causes problems to arise in that the place in which the apparatus is installed is limited, the operation becomes too complicated and the cost cannot be reduced. Therefore, an apparatus of the foregoing type cannot substantially be used at home. Since the body of the apparatus and the display device are connected to each other in a wired manner, the apparatus cannot be used in an arbitrary place, such as in an automobile, that is, portability is unsatisfactory.
  • a body of the apparatus capable of transmitting a background image signal, a lyrics signal and an accompanying sound signal is included in a wireless microphone. Therefore, only a conventional television receiver or radio receiver is required to play "karaoke" by using only one microphone without a necessity of using a special external apparatus individually separated from the wireless microphone. Therefore, a wireless accompaniment apparatus exhibiting reduced size, light weight, low cost and satisfactory portability can be provided.
  • FIG. 1 is a front view showing the portable wireless accompaniment apparatus according to a first embodiment.
  • the accompaniment apparatus has a function of displaying a caption representing lyrics on a display while being accompanied with accompanying sound as well as mixing accompanying sound with a vocal sound.
  • the caption may be displayed on a plain screen, the caption is, in this embodiment, displayed while being superimposed on a predetermined background image (although it is preferable that a kinetic image be employed, a still image may be employed) corresponding to the tune.
  • the present invention is not limited to the video-output accompaniment apparatus.
  • the present invention may be applied to a simple accompaniment apparatus that does not output an image but only outputs an accompanying sound. If the accompaniment apparatus is able to output an image, it acts as an accompaniment apparatus for outputting only an accompaniment sound if a receiver is a radio receiver in place of the television receiver.
  • the apparatus has a shape of a conventional wireless microphone comprising a microphone 11 and a microphone body 10.
  • the microphone body 10 is provided with a liquid crystal display device 41 for displaying the number indicating a tune, a state of reservation of tunes and a state of appointment, an operation panel 9 with which a selected tune is appointed, operation switches SW1 to SW5, connection terminals (jack switches) JACK1 to JACK5 and antennas ANT1 and ANT2.
  • the operation switch SW1 is a power source switch.
  • the operation switch SW2 is a microphone switch for setting an operation mode, such as whether or not echo effect is used.
  • the operation switch SW3 is a sound volume adjustment switch.

  • the operation switch SW5 is an earphone volume switch.
  • the jack switch JACK1 is a jack switch to which the earphone is connected.
  • the jack switch JACK2 is an output jack switch to which a wired jack of an external audio apparatus is connected.
  • the jack switch JACK3 is a jack switch to which a DC power source is connected.
  • the jack switch JACK4 is an input/output jack switch to which a wired jack of the external video apparatus is connected.
  • the jack switch JACK5 is a jack switch to which an auxiliary microphone is connected.
  • the antenna ANT1 is an antenna for transmitting a video signal as a television signal.
  • the antenna ANT2 is an antenna for transmitting an audio signal as an FM signal.
  • the microphone body 10 includes a video, caption, and accompaniment control unit.
  • the video, caption, and accompaniment control unit is operated when a function button of the operation panel 9 provided at the microphone body 10 is operated so as to transmit a background image, lyrics and an accompanying sound to a television receiver, an FM radio receiver or the like.

  • the video capture board 71 turns off the background image stored in the image/lyrics memory 40 and converts an external video signal (an NTSC signal) supplied from the external video apparatus into an RGB signal.
  • the video capture board 71 uses the external image selected arbitrarily by a user so that a video signal is transmitted from the antenna ANT1 in such a manner that the lyrics are moved as the tune proceeds.
  • the video signal transmitted from the video capture board 71 is, in the RF mixer 90, mixed with the audio data transmitted from the audio mixer 80.
  • a stereo audio signal transmitted from the audio mixer 80 is, in a monaural mixer 88, processed such that R and L channels are synthesized so as to be formed into a monaural voice signal, followed by being supplied to the RF mixer 90 through a modulator 89 of 4.5 MHz so as to be mixed with the video signal.
  • the video signal, transmitted from the RF mixer 90 and in the form in which the lyrics are superimposed on the background image, and a sound signal (monaural sound signal) indicating the accompanying sound are transmitted to a video receiving terminal unit, such as a television receiver or a monitor unit having a receiver from the TV transmission antenna ANT1 through an RF power amplifier 92 capable of multiplying the level by two times.
