现在汽车基本上已经普及，人待在车内时间越来越长，对车内的各种娱乐设施要求越来越高，对声音的要求也越来越高。汽车音响***作为汽车的一个组成部分，是车内能让驾车者与乘车者享受的娱乐工具，同时也是能使驾车人获得社会信息的手段，由此产生对汽车音响***功能、效果等有着较高的追求。由于车内是一个密闭的空间，而且空间比较小，反射信号也比较多，所以声场声效的处理、扬声器的布局以及怎样让车内实现剧场或影院的效果的问题尤其复杂。许多汽车的音响***过于简单，达不到全景声的效果，音效较差。例如专利201120455091.X公布的汽车三维环绕立体音响布置结构由仪表盘上的音响主机和顶部内饰板的扬声器组成，这种立体声环绕声场，声源比较单一，音效较差。Now that cars have basically become popular, people stay in the car for longer and longer, and the requirements for various entertainment facilities in the car are higher and higher, and the requirements for sound are also higher and higher. As an integral part of the car, the car audio system is an entertainment tool that can be enjoyed by drivers and passengers in the car. It is also a means of enabling drivers to obtain social information. higher pursuit. Since the inside of the car is a closed space, the space is relatively small, and there are many reflected signals, so the processing of the sound field sound effect, the layout of the speakers, and how to achieve the effect of a theater or theater in the car are particularly complicated. The sound system of many cars is too simple to achieve the effect of panoramic sound, and the sound effect is poor. For example, the three-dimensional surround sound arrangement structure of the automobile published by the patent 201120455091.X is composed of the audio host on the instrument panel and the speakers of the top interior panel. This stereo surround sound field has a relatively single sound source and poor sound effect.
