1988 V. Capel Audio & Hi-Fi Engineer's Pocket Bk. 37 A slice of piezo electric crystal, secured at one end.., generates an electrical signal when it is stressed by a vibrating cone in contact with the other... Several slices are used to produce a multimorph or sound cell, in which the sound actuates the slices directly.
