- 10. The portable apparatus as claimed in claim 1, wherein said transmitter comprises an FM modulator and an RF source for modulating and transmitting wirelessly said third electrical signal.
- 11. The portable apparatus as claimed in claim 1, wherein said MIDI information includes a plurality of note events of the selected one of the music pieces, each of said note events including time and speed information, pitch information and volume information, said processor unit being provided with a timer therein and being programmed to execute a play routine, said play routine being provided with a plurality of control parameters for controlling process of the selected one of the music pieces, said keyboard being operable so as to control said processor unit to modify said control parameters and information included in said note events to change accordingly tempo, key and other musical related controls of the selected one of the music pieces, said processor unit providing sequentially said note events to said MIDI sound source module in accordance with the time and speed information thereof counted by said timer.
- 12. The portable apparatus as claimed in claim 1, wherein the musical accompaniment information stored in the integrated circuit card further includes lyric data of the music pieces, said portable apparatus further comprising a caption expansion slot connected electrically to said processor unit and mounted to said casing, said processor unit retrieving the lyric data of the selected one of the music pieces from the integrated circuit card and providing the retrieved lyric data to said caption expansion slot.
- 13. The portable apparatus as claimed in claim 12, further comprising a caption display unit having a connector for engaging removably said caption expansion slot to connect electrically said caption display unit and said processor unit.
- 14. The portable apparatus as claimed in claim 13, wherein said caption display unit is a handheld display unit.
- 15. The portable computer as claimed in claim 14, wherein said caption display unit comprises:
- a second processor unit connected electrically to said connector for receiving the lyric data from said caption expansion slot;
- a first memory device, connected to said second processor unit, for storing character fonts therein;
- a second memory device, connected to said second processor unit, for storing the lyric data received by said second processor unit therein;
- a liquid crystal display; and
- a liquid crystal display controlling circuit which interconnects said second processor unit and said liquid crystal display to enable said liquid crystal display to show the lyric data from said caption expansion slot thereon.
- 16. The portable apparatus as claimed in claim 13, wherein said caption expansion slot is mounted pivotally to said casing to permit turning up or turning down of said caption display unit relative to said casing.
- 17. The portable apparatus as claimed in claim 12, further comprising a television caption system to be connected to said caption expansion slot for interfacing said processor unit and an external television set to enable the television set to display the lyric data from said caption expansion slot thereon.
