Description
The invention belongs to Karaoke (Karaoke) systems technology field.Specifically, karaoke OK system that the present invention released and control method thereof can be by respectively to sampling obtains the sampling clock umber of pulse, recently accurately calculates song composition (song score) with what the percentage form calculated resulting sampling clock umber of pulse from the sound signal of pick-up and tape, can be used as singer's score, and have a remote controller on the pick-up, can also select a pattern in the pattern of a left side/right side/stereo (below be designated as L/R/ST) as the sound output mode automatically.
Fig. 1 shows the block diagram of song composition counting circuit in a kind of traditional karaoke OK system.As seen from the figure, this song composition counting circuit comprises: amplification is from the amplifier 3 of the sound signal of pick-up 1, amplification is from the amplifier 4 of the sound signal of tape 2, one to respectively from the output signal of amplifier 3 and 4 carry out with computing with door 5, and the output signal of the output signal of basis and door 5 and amplifier 3 produces the gate generator 6 of clock pulse.The output signal that the number of the clock pulse of gate generator 6 output is proportional to amplifier 3 is added to the time on the gate generator 6.
Song composition counting circuit also comprises: the clock pulse counter 7 that the clock pulse of gate generator 6 outputs is counted, reading with clock pulse counter 7 output converts the time to again with the time adder 8 of this time and current time addition, one according to time of time adder 8 output with calculate the calculator 9 of song composition, and the song composition display unit 10 of the song composition that calculates of display calculator 9.
The working condition that below explanation is had the song composition counting circuit of said structure.
At first, be added to after amplifying by amplifier 3 from the sound signal of pick-up 1 on the input with door 5.Be added to after then amplifying from audio frequency (accompaniment) signal of tape 2 on another input with door 5 by amplifier 4.
Only just there is output signal to be added on the gate generator 6 when the output signal that is added with simultaneously on its two inputs respectively from amplifier 3 and 4 outputs with door 5.
In a single day gate generator 6 receives with door 5 the output signal and the output signal of amplifier 3 and just produces clock pulse, so the number of the clock pulse that produces of gate generator 6 output signal that is proportional to amplifier 3 is added to the time on the gate generator 6.For example, when the output signal of amplifier 3 was added to gate generator clock 6 last one second, gate generator 6 produced 100 clock pulse.
The clock pulse that 7 pairs of gate generators of clock pulse counter 6 produce is counted.Time adder 8 converts the reading of clock counter 7 to the time, and with this time and original time addition.At this moment, time adder 8 add just swing is once when surpassing certain predetermined value time.
For example, the accompaniment that time adder 8 has been pressed tape 2 after 99 times along with the reading of continuous input clock pulse counter 7 finishes, and the song composition that calculates of calculator 9 is 99 so.Like this, song composition display unit 10 shown song compositions are 99.
Yet the moment that calculator 9 is swung 100 times at time adder 8 resets to 0.Therefore, if the accompaniment that time adder 8 has been put tape 2 after 120 times along with the reading of continuous input clock counter 7 finishes, the song composition that calculated of calculator 9 will be 20 so.As a result, to demonstrate the song composition be 20 to song composition display unit 10.
