Abstract: The present invention discloses a moving-coil electroacoustic transducer, which is bar-shaped, and comprises a vibration system. The vibration system comprises 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 thrilled, and comprises an acoustic coil mounting portion located in the middle, plucked member mounting portions located at the two ends, and a support portion disposed between two long-axis edges of the acoustic coil mounting portion. In such a design, by using the integrally formed acoustic coil support, and disposing the plucked member mounting portions at the two ends of the acoustic coil support, a support portion is disposed between two long-axis edges of the acoustic coil mounting portion, and the acoustic coil support can be formed integrally, so that the problems of biased vibration and deformation on the long-axis side is solved, and meanwhile the manufacturing process is simplified, thereby making the manufacturing simpler.
