Moving-coil electroacoustic transducer

摘要

A moving-coil electroacoustic transducer is provided which is bar-shaped and includes a vibration system. The vibration system includes a vibration diaphragm, a bar-shaped acoustic coil, an acoustic coil support, and two plucked members. The acoustic coil sleeves the acoustic coil support and is combined with the vibration diaphragm through the acoustic coil support. The acoustic coil support is integrally formed; and includes an acoustic coil mounting portion located in the middle, dampening member mounting portions located at the two ends, and a support portion disposed between two long-axis edges of the acoustic coil mounting portion.
