濟南汽車音響改裝http://www.szanyuda.com/專家介紹汽車音響的揚聲器與家電揚聲器在頻響、功率、阻抗、靈敏度等方面基本一樣，但是，在制做工藝、使用材料、結構等方面有特殊設計。下面濟南孚卡悅聽的有關專家就給大家詳細介紹一下汽車揚聲器有哪些特點？

1、溫度：汽車在室外工作，隨氣候冷熱變化溫度差別大，所以車用揚聲器要抗溫度老化結構不能變形。
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、防潮濕：汽車在下雨、走有水路段、洗車時都要受到潮濕，所以車用揚聲器要防潮濕，現在多采用化學合成材料的音盆。
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、防塵土：家電揚聲器在房間內使用塵土少，而車內塵土多，需用防塵罩防止音圈磨擦產生噪音。
Speakers appliances use less dust in the room, while the car dust and more dust cap required to prevent the coil friction noise.

4、振動：車用揚聲器隨時隨地受到汽車運動時的振動沖擊，設計上要牢固不能松動。
Car Speakers by car anytime shock and vibration during exercise, designed to firmly can not loose.

5、噪音：考慮車內各種噪音和反射情況，使用的材料也有所不同，采用各種設計方式抵消不同的噪音，車內揚聲器安裝位置有限，為了聽音聲場定位，高音角度設計不同。
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：汽車供電電壓低，要想獲得大的功率，揚聲器的阻抗都較小，多使用4Ω有3.2Ω和2Ω甚至1Ω，使用使用雙音圈，并聯方法可達2Ω甚至更小，這種方法家用音響很少采用。
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.
