In general, in-line skates are used in combination with a boot shoe after arranging a plurality of rollers rotatably mounted on a support, and the user wears the shoes in a zigzag form. Repeat your leg movements to move forward.

Compared with roller skates, these inline skates have a beautiful appearance and the driving speed is very fast compared to general skate speeds, and are rapidly spreading among young people, and many clubs have many members on PC communication or Internet sites. Its popularity is increasing day by day.

The use of inline skates is recommended in a relatively large place because of the relatively fast running speed, but the use is also increased in narrow places because our living environment is not comfortable enough to provide such a place. Therefore, research is being actively conducted to inform people walking around that there is inline skating because of the high speed.

Utility Model Registration Publication No. 20-0192240 (Roller Skate with Music Output) (hereinafter referred to as "Preliminary Registration Design") discloses the construction of a skate that generates a melody by generating a constant voltage when driving inline skates. Doing.

Preferably, a "on / off" switch is connected between the voltage output terminal of the generator and the constant voltage circuit so that the output of the generator can be cut off / connected as necessary.

Preferably, the speaker for converting the melody output from the melody generation cycle into an audible sound and the melody generating circuit may be embedded in the boot as a thin piezoelectric speaker and one chip. In addition, the melody generating circuit can be replaced with a circuit for generating a siren as needed.

The clave cylinder bobbin cuts the circumference in the horizontal direction to axially couple the two guide disks to a cylindrical cylinder having a plurality of clad plates, spaced at predetermined intervals, and folds the clave plates upwards. Is composed of a winding coil connected between the two guide disks in connection with the clave plate.
