A lamellophone (also lamellaphone or linguaphone, from the Latin root 'lingua' meaning "tongue", i.e., a long thin plate that is fixed only at one end) is any of a family of musical instruments. The name comes from the Latin word "lamella" for "plate" and the Greek root "phonos" for "sound". The name derives from the way the sound is produced: the instrument has a series of thin plates, or "tongues", each of 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.
Lamellophones are categorised as 12 in the Hornbostel-Sachs system.
African lamellophones 
A large number of lamellophones originate in Africa, where they are known under different names including mbira, sanza, kisanji, likembe, kalimba, and kongoma. They play an important role in southeast African Music. They were reported as early as the 16th century, but there is no doubt they have a much longer history. The Caribbean marímbula is also of this family. The marímbula can be seen as a bass variant of the mbira and is sometimes used in hiphop music.
The tongues may be arranged in the manner of a piano and may be made small enough to play with individual fingers, hence the colloquial name "thumb piano." (Although some instruments, like the Mbira, have an additional rows of tongues, in which case not just the thumbs are used for plucking.)
Some conjecture that African lamellophones were derived from xylophones and marimbas. However, similar instruments have been found elsewhere; for example, the indigenous peoples of Siberia play wooden and metallic lamellophones with a single tongue.
Schaeffner's classification 
Schaeffner's musical instrument classification scheme has a post-prominent place for the linguaphones (lamellophones) at the second highest level of classification.
In 1932, Andre Schaeffner developed a new classification scheme that was "exhaustive, potentially covering all real and conceivable instruments" [Kartomi, p.176]. Schaeffner's system has only two top-level categories denoted by Roman numerals (Schaeffner, A.: Origine des instruments de musique, pp. 371-377.):
- I: instruments that make sound from vibrating solids;
- II: instruments that make sound from vibrating air (aerophones).
