NOVELTY - The apparatus has a piezoelectric layer (1406) arranged on a first electrode layer (1404), and a second electrode layer (1408) on the piezoelectric layer. Another piezoelectric layer (1410) is arranged on the second electrode layer, and a third electrode layer is arranged on the latter piezoelectric layer. An elastic layer is arranged on a portion of the third electrode layer. A portion of the first electrode layer generates strains in the piezoelectric layers. The elastic layer has one of silicon nitride, silicon oxynitride, silicon oxide, silicon, aluminum nitride, metal, and polymer.    USE - Apparatus for detecting sound in an electronic device. Uses include but are not limited to mobile telephones, multimedia Internet enabled cellular telephone, mobile TV receiver, wireless device, smartphone, Bluetooth device, personal data assistants (PDA), wireless electronic mail receiver, hand-held or portable computer, netbook, notebook, smartbook, tablet, printer, copier, scanner, facsimile device, Global positioning system receiver/navigator, camera, MPEG 1 Audio layer-3 player, camcorder, game console, wrist watch, clock, calculator, TV monitor, flat panel display, electronic reading device i.e. c-reader, computer monitor, auto display i.e. odometer display, cockpit control and/or display, camera view display i.e. display of rear view camera in vehicle, electronic photograph, electronic billboard or sign, projector, architectural structure, microwave, refrigerator, stereo system, cassette recorder or player, DVD player, compact disk player, videocassette recorder, radio, portable memory chip, washer, dryer, washer/dryer, parking meter, packaging e.g. electromechanical system (EMS), microelectromechanical system (MEMS) and non-MEMS, and aesthetic structure e.g. display of images on a piece of jewelry.    ADVANTAGE - The elastic layer is arranged on the portion of the electrode layer, and the portion of another electrode layer generates the strains in the piezoelectric layers, respectively, thus providing linear response, increased dynamic range, improved sensitivity, and ease of fabrication of a sense element.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of forming an acoustic microphone.
