A soli state rely ( ssr ) is an electronc swithig device utilizing discrete semiconductors , integrated circuit and microelectronic technologics to provide electrical isolation and signla coupling between the control circuit and the output circuit without the use of moving part or contacts 固体继电器本产品具有体积小、重量轻、灵敏度高、开关速度快、输出功率大、无触点抖动、无火花干扰、密封防水防磁防爆、高可靠、长寿命。
Displays is functioned under the electromagnetic theory and can be easily effect by the magnetic field . however , please notice that most of the speaker has built - in a big magnet which can effect the functioning and level down the quality of the displays . please do not use your monitor when magnets or electronic products such as speakers operating nearby 电脑显示器是利用电磁原理来运作的，因此磁场干扰的隔离相当地重要，很多消费者都将喇叭放在显示器两侧，而市面上防磁喇叭的防磁效果不一，因为喇叭后方有个相当大的磁铁，如果喇叭过于靠近显示器的话，就会造成干扰的情形，甚至于产生著磁现象而影响画面品质。
