Acoustic performance of some typical panel loudspeakers such as flat panel loudspeaker,electrostric tive polymer film loudspeaker and electromechanical film loudspeaker are examined in this paper,and applica tions of these panel acoustic actuators in active noise control,especially in intelligent acoustic structure and ac tive acoustic barrier are discussed in detail.
对平板扬声器、电致伸缩聚合物薄膜扬声器和机电薄膜扬声器等典型平面扬声器的结构和声学性能进行了比较研究,并就平面扬声器在有源噪声控制,尤其是智能声学结构和有源声屏障中的应用作了介绍和分析。
