Course Name

Electro-acoustic Transducers

Course Description

This course provides students the basic concepts analytical skills, and the state of the art techniques in electroacoustic transducers, such as receivers, loudspeakers, microphones, and earphones. Bring them to a level that they can establish physical model of an electroacoustic transducer, and prepare them doing independent research in the electroacoustic area. Both theory and practical application in sound-producing and sound-receiving transducers will be emphasized.
