1、家用扬声器在房间内使用，因此温度差小，而汽车在室外工作，随着气候变化无常，温差大，所以济南汽车音响http://www.sdcarmusic.com/扬声器要抗温度老化。
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、汽车在下雨时、走有水路段、洗车时都要受到潮湿的袭击，所以济南汽车音响扬声器需防潮，现在多采用防潮的化学合成材料音盆。
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、家电扬声器在房间内使用，故尘土少，而车内尘土多，济南汽车音响扬声器需要防尘罩防止音圈摩擦产生噪声。车用扬声器随时随地受到汽车运动时的振动冲击，所以设计上要牢固不能松动。
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、考虑到各种噪声和振动情况，所以使用的材料有所不同，济南汽车音响http://www.sdcarmusic.com/扬声器要采用各种方式抵消不同的噪声。汽车供电电压低，为了获得大的功率，扬声器的阻抗都较小，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.
