适用于便携通信设备的小尺度扬声器阵列研究

Research on Small Scale Loudspeaker Array for the Application in Mobile Communication Devices

重点关注在便携设备的尺度约束下通过扬声器阵列提升设备的声信号回放性能,主要包括以下两方面内容:(1)通过稳健性扬声器阵列算法提升声学回放系统的径向衰减;(2)在近场人头散射影响的条件下分析和提升系统性能。通过建立小尺度扬声器阵列实验系统对研究结果进行了实验验证。

This paper is focused on the application of the loudspeaker array to improve the acoustic emission performance with the limited size of portable devices, including improving the radial attenuation of the acoustic emission using robust array algorithm and analyzing and improving the performance with consideration of the near field head scattering effect. Experi- ments are carried out to demonstrate the performance of the proposed methods.
