A lamellophone (also lamellaphone or linguaphone) is a member of the family of musical instruments that makes its sound by a thin vibrating plate called a lamella or tongue, which is fixed at one end and has the other end free. When the musician depresses the free end of a plate with a finger or fingernail, and then allows the finger to slip off, the released plate vibrates. An instrument may have a single tongue (such as a Jew's harp) or a series of multiple tongues (such as a mbira thumb piano).

Linguaphone comes from the Latin root lingua meaning 'tongue', (i.e., a long thin plate that is fixed only at one end). Lamellophone comes from the Latin word lamella for 'small metal plate', and the Greek word φωνή phonē for 'sound, voice'.
