Abstract
The utility model belongs to the field of the electronic musical instrument, which comprises a note input circuit 1, a note keyboard 2, a tempo input circuit 3, a tempo keyboard 4, a pulse shaping counting circuit 5, a note generating circuit 6 and a loudspeaker 7. The utility model is characterized in that the note input circuit 1 is provided with a note signal output wire 8; the control signal output end 9 of the note input circuit 1 and the control signal output end 10 of the tempo input circuit 3 are connected with a relay 12 through an OR gate 11; the pulse shaping counting circuit 5 is connected with the note generating circuit 6 and is provided with a signal input wire 13. The utility model which is widely suitable for households, kindergartens and other occasions has the advantages of simple structure, easy realization, low cost, etc.
Description
The utility model belongs to the electronic musical instrument field, especially relates to a kind of numbered musical notation of blattnerphone use that cooperates from music performance apparatus.
At present, numbered musical notation generally is to adopt microcomputer or single-chip microcomputer to control realization from music performance apparatus, and it can play and store the music of more complicated, but cost is higher, realizes complexity, carries inconvenience.
Advantages such as the purpose of this utility model is to disclose a kind ofly to cooperate numbered musical notation that blattnerphone uses from music performance apparatus, has simple in structurely, realizes easily, and memory capacity is big, and is with low cost are widely used in family, kindergarten, music-lover and use.
The disclosed numbered musical notation of the utility model is from music performance apparatus, form by note typing circuit, note keyboard, beat typing circuit, beat keyboard, shaping pulse counting circuit, note generation circuit and loudspeaker, it is characterized in that note typing circuit has a note output line, the control signal output ends of the control signal output ends of note typing circuit and beat typing circuit is through one or be connected relay behind the door; The shaping pulse counting circuit produces circuit with note and links to each other, and a signal input line is arranged.Use the utility model, when need typing numbered musical notation music, the note output line links to each other with the microphone input jack of blattnerphone, and the output terminal of relay links to each other with the blattnerphone external power supply jack, and blattnerphone should be in recording state.The corresponding note key of successively pressing on the note keyboard is controlled different tones and length with the corresponding beat key on the beat keyboard, when pressing different note keys, note typing circuit will produce corresponding number train of impulses, and be transported to by the note output line in the microphone jack of blattnerphone, simultaneously, the control signal output ends of note typing circuit is a high level, makes blattnerphone record this pulse train string; When pressing different beat keys, the control signal output ends of beat typing circuit will be exported the positive pulse of corresponding width, make blattnerphone record blank signal corresponding to pulse width.
When the need numbered musical notation from music performance apparatus when playing, the signal input line of shaping pulse counting circuit links to each other with the earphone jack of blattnerphone, the tape that has recorded is put into blattnerphone, blattnerphone is in tone playing state, the shaping pulse counting circuit receives the output signal of blattnerphone, behind its shaping counting, the control note produces the note that circuit produces diaphone mediation length, plays out by loudspeaker.
Below with reference to accompanying drawing the utility model is further described.
Fig. 1 is a structure principle chart of the present utility model
Fig. 2 records the circuit electrical schematic diagram
Fig. 3 plays the circuit electrical schematic diagram
With reference to Fig. 1. Fig. 2, note typing circuit 1 has a note output line 8, the control signal output ends 10 of the control signal output ends 9 of note typing circuit 1 and beat typing circuit 3 through one or door be connected relay 12 after 11, note keyboard 2 links to each other with note typing circuit 1, beat keyboard 4 links to each other with beat typing circuit 3, shaping pulse counting circuit 5 has a signal input line 13 and links to each other with note generation circuit 6, and note produces circuit 6 and links to each other with loudspeaker 7.With reference to Fig. 2, note typing circuit 1 is made up of three 1/2 dual time-base ic NE556, constitutes a multi-resonant oscillating circuit and two monostable circuits respectively, and the temporary steady state pulse width of a monostable circuit is 1/40s, and another is 1/8 bat.Beat typing circuit 3 is made up of one 1/2 dual time-base ic NE556, constitutes a multi-resonant oscillating circuit form.With reference to Fig. 3, shaping pulse counting circuit 5 is made up of three operational amplifiers, three Schmidt triggers and 7 binary counter CC4024,6D trigger CC14174, note produces circuit 6 to be made up of king oscillator circuit 15 and frequency dividing circuit 16, and frequency dividing circuit 16 selects a selector switch CC4512,7 binary counter CC4024 and four to select a selector switch CC4052 to form by temperament generator M082, eight.
