Abstract

An electronic musical instrument comprises a plural number of component blocks capable of being coupled mechanically and electrically in succession and each having therein musical tone elements control means and at least one of the blocks having also musical tone signal generating means. Time range or tonal range of generated musical tones are changed according to how many blocks are connected consecutively in a predetermined or a selected order. The blocks can generate a series of musical tones in a sequence corresponding to a connecting sequence when a switch arranged on the leading block is operated, and a desired musical piece can be performed by operating performance operating means of each block. The electric musical instrument also can be used as an educational toy allowing infants to learn music while amusing and is convenient for transportation since it can be easily dismembered into each block.

Claims

1. An electronic musical instrument comprising at least three component blocks mechanically and electrically connectable in succession, each having tone elements control means and at least one of said blocks further having a tone signal generating means, and said plural number of blocks being connected in succession to change either one of a time range of a tone or a tone range of the tones generated therefrom.

2. An electronic musical instrument comprising a plural number of mechanically and electrically connectable component blocks connected in succession, each block being equipped with:

a tone producing means,

a first connector and a second connector allowing mechanical and electrical connection to the other blocks,

input means arranged on said first connector for inputting signals for starting production of tones of the block, and

output means arranged on said second connector for outputting a signal indicating termination of the tone signal generation of the block.

3. An electronic musical instrument according to claim 2 wherein each of said blocks comprises direction detecting means to detect a direction of the connected block and the elements of tones to be produced are controlled by an output from said direction detecting means.

4. An electronic musical instrument according to claim 3 wherein said direction detecting means controls durations of tones to be produced by outputs of the connected block.

5. An electronic musical instrument according to claim 2 wherein each of said blocks further comprises storage means for storing performance data including a plural number of musical notes and tone signal generating means driven by an output from said storage means.

6. An electronic musical instrument according to claim 2 wherein at least one of said plural number of blocks comprises a rest note for stopping generation of musical note for a predetermined time.

7. An electronic musical instrument according to claim 2 wherein at least one of said plural number of blocks comprises tone signal generating means driven by the signal from said input means, and mixing means for mixing the tone signal inputted from a preceding block through said input means with the tone signal from said tone signal generating means and transferring the mixed signal to a subsequent block.

8. An electronic musical instrument according to claim 2 wherein one of said plural number of blocks further comprises means for converting the tone signal into a tone.

9. An electronic musical instrument according to claim 8 wherein said one of the plural number of blocks further comprises a power source for supplying driving power to the blocks and a clock pulse generating means for supplying clock pulses to the blocks.

10. An electronic musical instrument according to claim 2 further comprising at least one branching connector for parallelly connecting some of said plural number of blocks.

11. An electronic musical instrument according to claim 2 further comprising connectors for parallelly connecting said plural number of blocks in a folded form.

12. An electronic musical instrument comprising a tone generating block for generating tone signals, a plural number of performance operating blocks having a plural number of pitch designating manipulators and consecutively connectable to said tone generating block, means for determining a tone range for each of said plural number of blocks depending on connected conditions, means for designating a predetermined pitch in said determined tone range when said each of plural number of manipulators is operated, and means for producing a musical tone of said designated pitch.

13. An electronic musical instrument comprising a tone generating block for generating tone signals, and a plural number of performance operating blocks having a plural number of pitch designating manipulators and connectable in succession to said tone block to make up a series wherein:

said tone generating block comprises;

first output means for outputting position indicating signals for indicating the positions of an operating block in said series, said operating block whose position in indicated by said position indicating signal sending a detected signal representative of the pitch of an operated pitch manipulator in response to said position indicating signal;

first input means for inputting the detected signals representing an operated pitch designating manipulator sent from said operating block whose position is indicated by said position indicating signal; and

tone generating means for generating a tone having a pitch corresponding to said detected signal; and

each of said plural number of performance operating blocks comprises;

second input means capable of being connected to one of said first output means and previous stages of the performance operating block in said series for inputting the position indicating signals outputted from said tone generating block;

position detecting means for detecting whether or not the connected positions of said performance operating block are as indicated by said position indicating signal;

second output means capable of being connected to subsequent stages of the performance operating block in said series for outputting said position indicating signals for detecting in said subsequent stages that the connected positions of the performance operating blocks are as indicated by said position indicating signal;

manipulator detecting means for detecting operation of said pitch designating manipulator;

third input means capable of being connected to said subsequent stages for inputting said detected signals; and

third output means capable of being connected to one of said first input means and said previous stages for outputting the detected signals representing operated pitch designating manipulators of the operating block detected by said manipulator detecting means when said position indicating signal indicates the position of the operating block, and for outputting said detected signal inputted from said subsequent stages through third input means when said position indicating signal signal does not indicate the position of the operating block.

14. An electronic musical instrument according to claim 13 wherein said first output means and said first input means are connected fixedly to said second input means and said third output means respectively, whereby said tone generating block includes one of said performance operating blocks.

15. An electronic musical instrument according to claim 13 wherein a plural number of pitch designating manipulators of said performance operating block are designed as key switches covering an octave.

16. An electronic musical instrument according to claim 13 wherein said plural number of pitch designating manipulators of said performance operating block are designed as button switches in a number of one octave.
