New types of acoustic transducers have recently emerged as a possible alternative to moving-coil loudspeakers. However, they have not met the performance for commercialization enough to replace existing loudspeakers. In this paper to identify the requirements for high performance, we derived an analytical model of a moving-coil loudspeaker based on physical acoustics and electroacoustics, and evaluated the simulated results of the model in terms of acoustic performance. Finally, we discussed the physical requirements of new acoustic transducers from the perspective of bass performance, tonal balance, decay time, and spatial directivity and then made some suggestions.
