For example, 2 ₂ , 2 ₃ . . . 2 ₇ , 2 ₈ are arranged vertically in parallel. These rod-shaped bodies 2 ₁ , 2 ₂ , 2 ₃ ...2 ₇ , 2 ₈
On the upper end surface 2a of the scale note names C, R, Mid... are written, and the rod-shaped bodies 2 ₁ , 2 ₂ , 2 ₃ ...2 ₇ , 2 ₈
As shown in the third figure, two conductors such as brass wires 3 ₁ , 3 ₁ , 3 2 , 3 _{2 .} . . 3 ₇ , 3 ₇ , 3 ₈ , etc. ₃₈ is buried as a part of the sensor. 5 is a speaker, 6 is a rubber foot of the base 1, and 7 is a space for installing the speaker 5, a battery, and an electronic circuit (none of which is shown) necessary for generating musical sounds.

The two brass wires 3 ₁ , 3 ₁ , 3 ₂ , 3 ₂ ...3 ₇ , 3
Sensors 4 ₁ to 4 each including ₇ , 3 ₈ , and 3 ₈ as one member
4 ₈ is a well-known non-contact switch that uses, for example, the capacitance of the human body, and is connected to musical tone generating circuits 8 ₁ , 8 ₂ , 8 ₃ . . . 8 ₈ as shown in FIG. 8 ₁ , 8 ₂ , 8 ₃ ...8 ₈ is a common amplifier 9
It is connected to the speaker 5 via.

Musical sound generation circuits 8 ₁ , 8 ₂ , 8 ₃ ... 8 ₈ are connected to two brass wires 3 ₁ , 3 ₁ , 3 ₂ , 3 of corresponding rod-shaped bodies 2 ₁ , _{2 2} , 2 ₃ ...2 ₇ , 2 ₈ , respectively. ₂ ...When a hand touches ₃₈ , ₃₈ and a contact detection signal is output from sensors ₄₁ to ₄₈ ,
Driven by the signal, the corresponding rod-shaped body 2 ₁ ,
Scale tone signals of 2 ₁ to 2 ₈ and 2 ₈ are output.

Thus, place the device on a desk, for example, and hold the rod-like bodies 2 ₁ to 2 ₈ in your hands along with the music while listening to the brass wires 3 ₁ , 3 _{1 to} 3.
₈ , 3 ₈ , the musical sound generation circuits 8 ₁ to 8 ₈ are driven by the contact detection signals output from the sensors 4 ₁ to 4 ₈ , and as a result, the rod-shaped body 2 ₁ that came in contact with the speaker 5 is driven.
The scale tones corresponding to ~ ₂₈ are emitted, and the music is played.

In the above embodiment, brass wires ₃₁ to ₃₈ were used as conductors for the sensors ₄₁ to ₄₈ provided on the rod-shaped bodies ₂₁ to ₂₈ , but copper plates, aluminum foils, tapes, etc. may also be used. can be attached to the upper end surface 2a of the rod-shaped bodies ₂₁ to ₂₈ outside the side surface 2b.

In addition, as the sensors 4 ₁ to 4 ₈ , non-contact switches were used in the above embodiments, but ordinary mechanical switches were used, and the switches were built in rod-shaped bodies made of an elastic material such as foamed synthetic resin. Good too.

Furthermore, the rod-shaped bodies 2 ₁ to 2 ₈ may be made of an elastic piezoelectric material, or an elastic piezoelectric material may be housed in a hollow body made of an elastic material, and electrodes may be provided on the elastic piezoelectric material to form the rod-shaped bodies. It is also possible to use sensors 4 ₁ to 4 ₈ that can obtain a voltage as a contact detection signal by grasping _{2 1} to 2 ₈ by hand. Alternatively, the sensors 4 ₁ to 4 ₈ may be touch sensor circuits that use an electric conductor, such as a brass wire, and utilize the induced hum generated when a human body comes into contact with the conductor.

FIG. 5 shows a modified example circuit of the electronic circuit shown in FIG. In this circuit, control circuits 10 ₁ , 10 ₂ , 10 ₃ are connected between sensors 4 ₁ to 4 ₈ and musical tone generation circuits 8 ₁ to 8 ₈ .
... ₁₀₈ is interposed, and when a contact detection signal is output from the sensors ₄₁ to ₄₈ , the control circuits ₁₀₁ to ₁₀₈
A control signal is outputted from the control signal, and this control signal causes the musical tone generating circuits 8 ₁ to 8 ₈ to control the rod-shaped bodies 2 _{1 to 8} held by the hand.
It is designed to oscillate a scale tone signal corresponding to 2 ₈ .

FIG. 6 shows yet another example of the electronic circuit.

Alternatively, a device using an elastic piezoelectric material as described above may be connected. According to this circuit, a scale tone whose volume changes depending on the strength with which the rod-shaped object is gripped is emitted from the speaker 5, and the grip strength can be determined from the volume.

Although the speaker 5 and the amplifier shown in the first figure are equipped with the speaker 5 and the amplifier on the base 1, other audio equipment can be used without being equipped with these.

(Effects of the invention) As described above, according to this invention, it is possible to not only synchronize the fine movements of fingers, etc., and grasping movements of the hand of physically disabled people with their sense of touch and vision, but also with their sense of hearing. Since the results of functional recovery can be grasped in synchronization and rehabilitation training can be performed while enjoying music, the efficiency of hand rehabilitation can be further improved than before.
