According to the second invention, the musical sound is controlled by detecting the position of pressure applied to the human body by the human body's touching or "tapping"action; According to the invention, human ``touch'' or ``
The musical sound is controlled by detecting the amount of pressure applied to the human body by the action of "tapping", and according to the fourth invention, the vibration sound generated from the human body by the action of "touching" or "tapping" is detected. to control the musical tone. This makes it possible to convert human actions such as "touching" or "tapping" into musical sounds, and it is possible to obtain various unique effects in rhythmic gymnastics and other fields.

[Example code] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 and FIG. 2 are explanatory diagrams of the first embodiment.

In FIG. 2, ``■'' is a touch switch provided in each part of the human body, and diodes 2 are connected in cascade.

A plurality of touch switches 1 to which the diodes 2 are connected are connected in a matrix as shown in FIG. A switch on/off detection circuit 4 is connected to the line. The decoder 3 decodes the count output of the counter 5, and when the count output changes from rOJ to rNJ, it sequentially sets the θth to Nth row lines of the matrix to the “I(” level. A switch on/off detection circuit 4 outputs a clock pulse Φ of a constant period to a clock input terminal GK of a counter 5.
Output to. This causes data “0” from counter 5.
~rNJ is repeatedly output, and the Oth to Nth row lines of the matrix are sequentially and repeatedly scanned. Therefore, when any of the touch switches l turns "ON", that 'O'
When the row line of the touch switch l that is set to "N" is at the "H" level, the "I(" level is output to the column line of the touch switch l. The switch on/off detection circuit 4 outputs the count output of the counter 5. By checking the signal level of each column line of the matrix, it is possible to detect the position of the touch switch l that is turned "ON" on the matrix, that is, in which row and column the touch switch l is located. Position data PD indicating the detected position is output to the musical tone signal forming circuit 6 as musical tone control data.

The musical tone signal forming circuit 6 is connected to the switch on/off detection circuit 4
A musical tone signal having a pitch corresponding to the position data PD from the input terminal is formed and outputted to the speaker 7.

With this configuration, first, one of the touch switches l located on each part of the human body is turned "ON" in response to a human's "touching" or "tapping" action. That is, when the part of the human body on which the touch switch 1 is located touches or hits an external object or touches or hits itself, the touch switch is applied to a part of the body that receives pressure from the action. 1 is selectively turned "ON".

The musical tone signal forming circuit 6 then forms a musical tone signal and outputs it to the speaker 7 according to the position on the matrix of the tab switch I that is turned ON. The action of "hitting" produces a musical tone with a pitch that corresponds to the position of the human body that receives pressure.

Note that it may also be a device that changes the volume or timbre of a musical tone signal, or a device that changes the performance speed of an automatic rhythm tone in response to the position detection data PD from the switch on/off detection circuit 4. . In this case, for example, a musical sound is generated with a volume or tone depending on the position of the human body that receives pressure due to the human's "touching" or "tapping" action.

3 and 4 are explanatory diagrams of the second embodiment.

In this embodiment, conductive rubber 11 is provided on each fingertip of a human being. These conductive rubbers 11 are connected in parallel to the power supply voltage "+V" through a resistor 12, as shown in FIG. The pressure detection circuit 14
It's like you have to touch the input. Pressure detection circuit 1
4 constantly checks the output voltage of each amplifier 13, and when the output voltage of any amplifier 13 becomes lower than a certain level, a recognition signal for identifying that amplifier 13 and a pressure detection signal corresponding to the output voltage are provided. (consisting of an analog signal or a digital signal) is output to the musical tone signal forming circuit 15 as musical tone control data. The musical tone signal forming circuit I5 forms a musical tone signal having a pitch corresponding to the touch recognition signal output from the pressure detection circuit 14, controls the level of this musical tone signal by the pressure detection signal, and outputs it to the speaker 16.

With such a configuration, the speaker 16 outputs sounds with different pitches for each conductive rubber 11 that receives pressure.
A musical tone is generated with a volume corresponding to the amount of pressure received by the device.

In this embodiment as well, the pitch or timbre (or timbre, volume) of the musical tone signal or the performance speed of the automatic rhythm tone is changed in response to the pressure detection signal (or recognition signal) from the pressure detection circuit 14. It may also be something that allows you to do so. In this case, for example, human "touch" or "
The action of "hitting" produces a musical tone with a pitch or tone that corresponds to the amount of pressure the human body receives.

FIG. 5 and FIG. 6 are explanatory diagrams of the third embodiment.

In the case of this embodiment, bone conduction microphones 21 are attached to each part of the human body. This bone conduction microphone 21 is a microphone that picks up the vibration sound of bones near the body surface, and uses a piezoelectric element as a pickup sensor. Bone conduction microphone 2
I is worn with a belt or rubber band so that it can be attached closely to bones such as the waist, wrists, ankles, knees, and elbows of the human body. The mounting position is indicated by diagonal lines in FIG. Each bone conduction microphone 2 is connected to a vibration sound detection circuit 22. The vibration sound detection circuit 22 constantly checks the output of each bone conduction microphone 21, and when the output of any bone conduction microphone 21 becomes larger than a certain level, a recognition signal and a recognition signal for identifying that bone conduction microphone 21 are generated. A vibration sound detection signal (consisting of an analog signal or a digital signal) corresponding to the output is outputted to the musical tone signal forming circuit 24 as musical tone control data. The musical tone signal forming circuit 24 forms a musical tone signal with a pitch corresponding to the recognition signal output from the vibration sound detection circuit 22, controls the level of this musical tone signal by the vibration sound detection signal, and outputs it to the speaker 24.

With this configuration, the speaker 24 generates a musical sound having a different pitch for each bone conduction microphone 21 that receives pressure and a volume corresponding to the magnitude of the vibration sound detected by the bone conduction microphone 21.

In this embodiment as well, the pitch or timbre (or timbre, volume) of the musical tone signal or the performance speed of the automatic rhythm tone is changed in response to the vibration sound detection signal (or recognition signal) from the detection circuit 22. It may also be something that allows you to do so. Furthermore, the bone conduction microphone 21 on the wrist can be held in the hand if it can be held in close contact with the user.

Further, in each of the above embodiments, the detection circuit 4°1=1.
22 On/off detection result of switch l, amplifier 13
The detection result of the output of the bone conduction microphone 21 and the detection result of the vibration sound from the bone conduction microphone 21 are output as musical tone control data as they are, but each detection circuit forms predetermined musical tone control data based on its detection result and outputs it. You may also do so. In short, each detection circuit only needs to output musical tone control data in accordance with the detection results.
