Why does an old typewriter jingle?

Increase friction, give some strength when typing, etc.

1. Check the typewriter to make sure it is in normal condition.

1, rough paper is used, which can increase the friction and * * * degrees when the typewriter keyboard is struck, thus producing more obvious sound effects.

2. When you press the keyboard, you should give enough strength to ensure that each key can completely fall and contact with the letter wheel of the typewriter, and type at a stable speed and rhythm to avoid being too fast or too slow to obtain a consistent sound effect.
