附图说明
以下将结合附图对本发明的实施方案进行描述，其中：
图1为根据本发明实施方案示出的扩展型车用喇叭的结构方框图。
附图标记：1遥控手柄；2声音定向设备；3大功率语音播放设备；4小功率语音播放设备；5声音驱动设备
具体实施方式
下面将参照附图对本发明的扩展型车用喇叭的实施方案进行详细说明。
喇叭，又称作为扬声器，是一种把电信号转变为声信号的换能器件，扬声器的性能优劣对音质的影响很大。扬声器在音响设备中是一个最薄弱的器件，而对于音响效果而言，他又是一个最重要的部件。扬声器的种类繁多，而且价格相差很大。音频电能通过电磁，压电或静电效应，使其纸盆或膜片振动并与周围的空气产生共振(共鸣)而发出声音。
低档塑料音箱因其箱体单薄、无法克服谐振，无音质可言(也有部分设计好的塑料音箱要远远好于劣质的木质音箱)；木制音箱降低了箱体谐振所造成的音染，音质普遍好于塑料音箱。
通常多媒体音箱都是双单元二分频设计，一个较小的扬声器负责中高音的输出，而另一个较大的扬声器负责中低音的输出。
挑选音箱应考虑这两个喇叭的材质：多媒体有源音箱的高音单元现以软球顶为主(此外还有用于模拟音源的钛膜球顶等)，他与数字音源相配合能减少高频信号的生硬感，给人以温柔、光滑、细腻的感觉。多媒体音箱现以质量较好的丝膜和成本较低的PV膜等软球顶的居多。
当前的车用喇叭无法提供更多的警务辅助功能。为了克服上述不足，本发明搭建了一种扩展型车用喇叭，能够利用现有的车用喇叭资源，警示附近是否存在通缉犯，从而解决上述技术问题。
图1为根据本发明实施方案示出的扩展型车用喇叭的结构方框图，所 述系统包括遥控手柄、声音定向设备、大功率语音播放设备、小功率语音播放设备和声音驱动设备，所述遥控手柄用于以手动方式控制所述大功率语音播放设备的打开或关闭，还用于以手动方式控制所述小功率语音播放设备的打开或关闭；

在所述扩展型车用喇叭中，还包括：无线通信设备，设置车辆的车体的前端，用于与远端的警务管理中心建立双向的无线通信链路连接。
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。
采用本发明的扩展型车用喇叭，针对现有技术中车用喇叭警务活动参 与度低的技术问题，通过在现有的车用喇叭硬件上集成定制的图像处理设备对周围进行通缉犯辨识，并通过车用喇叭功率输出部件的变化提醒警务人员和附近群众，从而能够更多地参与警务活动。
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。
