The tymbal is a sound producing organ found in the abdomen of cicadas. The tymbal consists of alternating stiff and flexible membranes. The song is produced by using muscle to deform this structure producing a click. The muscle tension is then released producing another click. This process is repeated rapidly and can be used to produce a very loud call.
The sound is not produced by stridulation as is the case in other insects.
