济南汽车音响改装http://www.sdcarmusic.com/专家介绍汽车音响的扬声器与家电扬声器在频响、功率、阻抗、灵敏度等方面基本一样，但是，在制做工艺、使用材料、结构等方面有特殊设计。下面济南孚卡悦听的有关专家就给大家详细介绍一下汽车扬声器有哪些特点？

1、温度：汽车在室外工作，随气候冷热变化温度差别大，所以车用扬声器要抗温度老化结构不能变形。
Automotive work outdoors, with hot and cold climate changes in temperature difference is big, so car speakers to be resistant to temperature aging structure can not be deformed.

2、防潮湿：汽车在下雨、走有水路段、洗车时都要受到潮湿，所以车用扬声器要防潮湿，现在多采用化学合成材料的音盆。
Car in the rain, go water sections, when the car wash will be subject to moisture, so the car speakers to be anti-moisture, and now use more synthetic material cone.

3、防尘土：家电扬声器在房间内使用尘土少，而车内尘土多，需用防尘罩防止音圈磨擦产生噪音。
Speakers appliances use less dust in the room, while the car dust and more dust cap required to prevent the coil friction noise.

4、振动：车用扬声器随时随地受到汽车运动时的振动冲击，设计上要牢固不能松动。
Car Speakers by car anytime shock and vibration during exercise, designed to firmly can not loose.

5、噪音：考虑车内各种噪音和反射情况，使用的材料也有所不同，采用各种设计方式抵消不同的噪音，车内扬声器安装位置有限，为了听音声场定位，高音角度设计不同。
Consider various interior noise and reflections, the materials used are different, using a variety of different design approach to offset the noise, limited car speaker installation location,listening to the sound field positioning, different pitch angle design.

7、阻抗小：汽车供电电压低，要想获得大的功率，扬声器的阻抗都较小，多使用4Ω有3.2Ω和2Ω甚至1Ω，使用使用双音圈，并联方法可达2Ω甚至更小，这种方法家用音响很少采用。
Automotive supply voltage is low, in order to obtain a large power, speaker impedance are small, multi-use 4Ω have 3.2Ω and 2Ω even 1Ω, that use dual voice coil, shunt method up to 2Ω even smaller, this approach home audio rarely used.
