Abstract
A karaoke system used in audio-visual education or for dynamic real-time composition of words and/or speech features that the music and song or speech are replayed by means of optical disk, magnetic disk, or ROM while the characters about song or speech are displayed in dot matrix form. Its advantages include high reliability and fidelity.
Description
What the present invention relates to is to adopt dot matrix character to show the karaoke OK system of the lyrics, literal and spoken and written languages, the invention belongs to the technical field of showing sound equipment.
Existing Karaoke technology is the synthetic of video technology and electronic audio technology, and common have a Laser Vision, and CD-v and V-CD etc. often are made up of monitor or television machine, video disc player or special-purpose karaoke machine and Karaoke or MTV video disc etc.
This karaoke OK system creating an entertainment environment to people when, has also limited its use occasion.Because the use of system must have the monitor or television machine, be to make more people can see the lyrics, literal and language and characters synchronous time mark for numerous occasions, the picture of monitor or television machine must be very big, and the cost of its system will be very high.In addition, owing to must use the monitor or television machine, the system that makes does not have portability.
At the portability of karaoke OK system, in the patent documentation that some are published, be described, for example: 90221081, design a kind of portable liquid crystal and shown the Karaoke cassette player.On tape recorder, set up LCDs, show the tape lyrics and rhythm prompt content synchronously.In this patent, the coding of the lyrics and rhythm prompt content is recorded on the magnetic track of tape, and tape is repeatedly using the back to be difficult to guarantee its reliability.In addition, what the record of music and voice adopted is analog form, and its fidelity is difficult to compare with contemporary music.
There is many disadvantages for overcoming existing karaoke OK system technology, special proposition the present invention.
The object of the invention is to provide a kind of employing CD, disk or ROM technology, in played songs (music and lyrics voice), shows the karaoke OK system of lyric characters and language and characters synchronous time mark with the dot matrix character display.
The present invention is applied in electronic teaching, at whole literal of more complete sentence of dot matrix character display or word letter, export display text voice synchronous markers and voice simultaneously synchronously, realize the dynamic, synthetic in real time of literal and language or voice, be very valuable in language teaching, it has played the effect that the teacher is difficult for playing to a certain extent.
Dot matrix character of the present invention shows that the purpose of CD, disk or ROM card karaoke OK system (being called for short " system ") can be realized by following technical measures: system of the present invention comprises Play System and manufacturing system two major parts, Play System is characterized in that by CD or disk or ROM card, driver or ROM card, decompress(ion) and display controller, dot matrix character display, multi-channel audio amplifying circuit, pick-up and loud speaker are formed, described driver is the read-write equipment of CD or disk, its output signal input decompress(ion) and display controller; Described ROM card is meant by mask ROM, PROM, EPROM or E
2The data memory hardware card that PROM chip and peripheral companion chip are formed.
Decompress(ion) and display controller are made up of microprocessor or single-chip microcomputer or the attached peripheral chip that helps of special-purpose decoder chips.Obtain compressed music from CD, disk or the ROM card of driver or ROM card, voice, literal code and language and characters synchronous time mark data, by analysis, decompress(ion) divides two-way to export synchronously; With music and the synthetic amplifying circuit of voice signal input multi-channel audio, with literal code and language and characters signal input matrix display, synthetic amplifying circuit of multi-channel audio and pick-up join, and join with decompress(ion) and display controller, join with loud speaker, join with panel control switch.The audio signal that the singer that reception is exported from pick-up sends receives the audio signal through decomposing from decompress(ion) and display controller.To export loud speaker to after the synthetic amplification of two road input signals.Working method is controlled by panel control switch.
Matrix display and decompress(ion) and display controller join, and accept the display text coding and the language and characters synchronous time mark signal of its output.
Loud speaker is to connect with the synthetic amplifying circuit of multi-channel audio, and it reflects from the audio mixing of the synthetic amplification of the audio signal of CD, disk or the ROM card of the singer's of pick-up output audio signal, decompress(ion) and display controller output and peripheral reflection echo etc.
Described matrix display is during for relatively large " system ", employing be LED dot matrix character display, when being pocket, adopt lattice lcd display for " system ".
