How the indirectly struck idiophone makes its sound
In the Hornbostel–Sachs system, which classifies instruments by how they produce sound, the indirectly struck idiophone belongs to the shaken and scraped idiophones: the body is shaken, scraped or split – rattles, maracas and guiros.
More broadly it is one of the idiophones, where the solid body of the instrument itself vibrates, without strings or a stretched membrane.
Its timbre – the colour that lets you tell it apart from other instruments playing the same note – comes from the mix of overtones its body and resonator emphasise.
From Wikipedia

Struck idiophones are categorised as 11 in the Hornbostel-Sachs system. There are two main categories of struck idiophones, directly (111) and indirectly (112) struck.
