    Abstract

    This paper presents a novel flat loudspeaker with improved sound frequency response. Flat loudspeakers provide advantages of compact dimensions and high durability. Known flat loudspeaker technology is based on high modal density. However, the resonances in the panel are complex and difficult to control, which often leads to complicated computations and insufficient low frequency response. The flat loudspeaker in this paper comprises a novel panel structure, which offers low density, high stiffness, and efficient space utilization. Furthermore we have developed a simple and stable control mechanism to obtain flat sound frequency response. Experimental results show that our method effectively improves the performance of the flat loudspeaker with extended low-frequency response.
