Natural transducers are a source of inspiration for smart design of systems. Here, I present an example of such a transducer that is used by male field crickets to produce a very loud mating song. Field crickets do not use vocal cords to produce sound, rather they use specialised regions on their forewings and mechanical actuation to radiate sound. With careful measurements on the forewings, I have constructed a finite element model and use it to study the transduction mechanism and show how the song is produced. Inspired by how the cricket actuates and efficiently produces such a loud sound, I have come up with a design for MEMS (Micro Electro Mechanical Systems) speakers. I have been able to realize my first prototypes using simple fabrication processes. By electrostatically actuating the MEMS devices, I obtain a sound pressure of 70 dB SPL at a distance of 10 cm.
