1、家用揚聲器在房間內使用，因此溫度差小，而汽車在室外工作，隨著氣候變化無常，溫差大，所以濟南汽車音響http://www.szanyuda.com/揚聲器要抗溫度老化。
Household speaker in the room to use, so the temperature difference is small, while the car to work outdoors, along with climate variability, temperature, so Jinan car stereo speakers to the anti-temperature aging.

2、汽車在下雨時、走有水路段、洗車時都要受到潮濕的襲擊，所以濟南汽車音響揚聲器需防潮，現在多采用防潮的化學合成材料音盆。
Car when it rains, water walking sections will be subject to attack when wet washing, so Jinan car stereo speakers need moisture, now use more synthetic material cone moisture.

3、家電揚聲器在房間內使用，故塵土少，而車內塵土多，濟南汽車音響揚聲器需要防塵罩防止音圈摩擦產生噪聲。車用揚聲器隨時隨地受到汽車運動時的振動沖擊，所以設計上要牢固不能松動。
Speaker in the room using the appliance, so less dust, and dusty car, Jinan car stereo speakers dust cover required to prevent the coil friction noise. Car speaker wherever vibration and shock by car during exercise, so the firm can not

loose design.

4、考慮到各種噪聲和振動情況，所以使用的材料有所不同，濟南汽車音響http://www.szanyuda.com/揚聲器要采用各種方式抵消不同的噪聲。汽車供電電壓低，為了獲得大的功率，揚聲器的阻抗都較小，多使用4Ω、3.2Ω和2Ω。
Taking into account all kinds of noise and vibration, so the material is different, Jinan car stereo speakers to be used in various ways to offset the different noise. Automotive supply voltage is low, in order to get high power, impedance of the speaker are small, multi-use 4Ω, 3.2Ω and 2Ω.
