喇叭的种类很多，按其换能原理可分为电动式(即动圈式)、静电式(即电容式)、电磁式(即舌簧式)、压电式(即晶体式)等几种，后两种多用于农村有线广播网中；按频率范围可分为低频扬声器、中频扬声器、高频扬声器，这些常在音箱中作为组合扬声器使用。
按换能机理和结构分动圈式(电动式)、电容式(静电式)、压电式(晶体或陶瓷)、电磁式(压簧式)、电离子式和气动式扬声器等，电动式扬声器具有电声性能好、结构牢固、成本低等优点，应用广泛；
按声辐射材料分纸盆式、号筒式、膜片式；按纸盆形状分圆形、椭圆形、双纸盆和橡皮折环；按工作频率分低音、中音、高音，有的还分成录音机专用、电视机专用、普通和高保真扬声器等；按音圈阻抗分低阻抗和高阻抗；按效果分直辐和环境声等。

常见扬声器有以下几种：纸盆音色自然、廉价、较好的刚性、材质较轻灵敏度高，缺点是防潮性差、制造时一致性难以控制，但顶级HiFi系统中用纸盆制造的比比皆是，因为声音输出非常平均，还原性好。防弹布，有较宽的频响与较低的失真，是酷爱强劲低音者之首选，缺点是成本高、制作工艺复杂、灵敏度不高轻音乐效果不甚佳。羊毛编织盆，质地较软，它对柔和音乐与轻音乐的表现十分优异，但是低音效果不佳，缺乏力度与震撼力。PP(聚丙烯)盆，他广泛流行于高档音箱中，一致性好失真低，各方面表现都可圈可点。此外还有像纤维类振膜和复合材料振膜等由于价格高昂极少应用于普及型音箱中。

另外，GPS是英文Global Positioning System(全球定位系统)的简称。GPS起始于1958年美国军方的一个项目，1964年投入使用。20世纪70年代，美国陆海空三军联合研制了新一代卫星定位系统GPS。主要目的是为陆海空三大领域提供实时、全天候和全球性的导航服务，并用于情报搜集、核爆监测和应急通讯等一些军事目的，经过20余年的研究实验，耗资300亿美元，到1994年，全球覆盖率高达98％的24颗GPS卫星星座己布设完成。
GPS导航系统的基本原理是测量出已知位置的卫星到用户接收机之间的距离，然后综合多颗卫星的数据就可知道接收机的具体位置。要达到这一目的，卫星的位置可以根据星载时钟所记录的时间在卫星星历中查出。而用户到卫星的距离则通过记录卫星信号传播到用户所经历的时间，再将其乘以光速得到(由于大气层电离层的干扰，这一距离并不是用户与卫星之间的真实距离，而是伪距(PR，)：当GPS卫星正常工作时，会不断地用1和0二进制码元组成的伪随机码(简称伪码)发射导航电文。GPS系统使用的伪码一共有两种，分别是民用的C/A码和军用的P(Y)码。C/A码频率1.023MHz，重复周期一毫秒，码间距1微秒，相当于300m；P码频率10.23MHz，重复周期266.4天，码间距0.1微秒，相当于30m。而Y码是在P码的基础上形成的，保密性能更佳。导航电文包括卫星星历、工作状况、时钟改正、电离层时延修正、大气折射修正等信息。它是从卫星信号中解调制出来，以50b/s调制在载频上发射的。导航电文每个主帧中包含5个子帧每帧长6s。前三帧各10个字码；每三十秒重复一次，每小时更新一次。后两帧共15000b。导航电文中的内容主要有遥测码、转换码、第1、2、3数据块，其中最重要的则为星历数据。当用户接受到导航电文时，提取出卫星时间并将其与自己的时钟做对比便可得知卫星与用户的距离，再利用导航电文中的卫星星历数据推算出卫星发射电文时所处位置，用户在WGS-84大地坐标系中的位置速度等信息便可得知。
采用本发明的太阳能喇叭自适应控制系统，针对现有技术中车载喇叭播放模式单一的技术问题，通过在现有的车载喇叭的硬件基础上，在进行太阳能改造之外，增加了针对性的多个图像处理设备以及自适应控制机制完成前方拥堵情况的检测以及播放频率的自适应调整，从而提升车载喇叭的播放效果。
可以理解的是，虽然本发明已以较佳实施例披露如上，然而上述实施例并非用以限定本发明。对于任何熟悉本领域的技术人员而言，在不脱离本发明技术方案范围情况下，都可利用上述揭示的技术内容对本发明技术方案做出许多可能的变动和修饰，或修改为等同变化的等效实施例。因此，凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化及修饰，均仍属于本发明技术方案保护的范围内。
