    济南btc365谈喇叭烧坏的原因
    2014-11-13 18:00:40

    1、济南btc365http://www.sdcarmusic.com/专家谈到长时间超负荷驱动喇叭,喇叭会由于过热而把喇叭烧坏,由于线圈的温度升高,使某些构造部份产生凝结,特别是粘合音圈的胶水,决裂或烧毁,正常运用下线圈的温度就有180 摄氏度或更高,不正常运用肯定就会被烧坏。
    Prolonged overload driving the speaker, the speaker will burn due to overheating of the speaker, since the temperature of the coil increases, so some configurations produce condensation part, especially the voice coil bonding glue, break or burn, under normal use coil the temperature there is 180 degrees or higher, certainly not normal use will be burned.
    2、机械式毛病,超负荷的驱动喇叭使得纸盘挪动超出范围并和线圈别离,或线圈和线圈座别离,纸盘折边或喇叭支撑圈变形而招致音圈移位,以上任一种情形一旦发作,都能够使喇叭产生毛病。
    Mechanical problems, driver overload the tray to move out of range speaker makes and leave the coil or coils and coil holder parting, folding tray or speaker voice coil support ring deformation incurred shift, more than either case once the attack , are able to produce the horn illnesses.
    3、喇叭的毛病也可能是以上两种方式的分离,比方功放忽然输出一个很大的霎时能量,这个能量能够是声音忽然开大,喇叭就会有一个激烈的振动,使得线圈脱离了磁力间隙,当它回去的时分可能偏心而没法回恢复位,又或者音圈己经变形,不是圆柱的外形了。
    Speaker of the above problems may be separated in two ways, for example, the output of the amplifier of a sudden a lot of instant energy, this energy can be a voice suddenly turn up, there will be a fierce speaker vibration, making the coil out of the magnetic gap, when it is possible to go back to the division and could not get back the recovery bit eccentric, or coil already deformed, not the shape of a cylinder.

    4、功放假如有直流输出,那一定会烧掉中低音扬声器,以至极少数的高音扬声器也会烧掉。缘由是低音扬声器分音途径上没有电容器隔离直流,直流一输出就像把直流电通入扬声器中,连分音器线圈一同烧得焦黑。因而功放接线的时分要留意一下,要先用万用表丈量功放输出端能否有直流输出。
    If there is a DC amplifier output, it must be burned in a subwoofer to extremely small number of tweeters will be burned. There is no reason on isolated DC capacitor subwoofer crossover way, the DC output as a direct current through the speaker, and even crossover coil with burned charred. Thus the amplifier wiring division should look at, first with a multimeter to measure the output of the amplifier can have DC output.
