Origin

The character 鐘 combines metal (金) on the left, showing this is a thing made of metal, with the component 童 on the right that serves as a sound hint for pronunciation. The metal radical makes sense because bells and gongs are cast from bronze or other metals and produce sound through vibration. The right component doesn't add meaning but guides you toward the character's sound, which in Chinese-derived reading is close to how 童 is pronounced. Together, the shape captures the idea of a metal object that rings.
