Changes in air pressure created by sound waves cause the membrane to move. The backplate is perforated to let the air flow through it and is designed to remain rigid since the air can pass through its perforations.
WebAug 15, 2024 · One of the key requirements for MEMS speakers is to increase the sound pressure level (SPL) while keeping the size as small as possible. In this paper we present a MEMS speaker based on piezoelectric bimorph cantilevers that produces a higher SPL than conventional unimorph cantilever speakers. The active diaphragm size is 1.4 × 1.4 mm 2.
