This work attempts to decorate the exploding field of "Electroacoustic Transducers," focusing the conceptualization, design, development, modeling, simulation, and manufacturing of transducers like microphone, woofer, and miniature-loudspeaker. Also, a loudspeaker in 4C products like earbud and insert earphone is targeted. Modeling, simulation, fabrication, and testing are 4 main pillars of this work. Dynamic Analogy using equivalent circuit is used to develop analytical model aided by micro-tensile test and finite element simulation. Laser vibrometry and an anechoic chamber measurement are...
