通过上面对L2系列电振动喇叭振动系统的理论分析及定量的试验研究,可知造成喇叭寿命不能过关的根本原因不是振动系统,因此,还须对其电磁系统及继电系统进行理论分析和定量的试验研究。 三、电磁系统 1。电磁拉力 喇叭电磁铁的磁拉力是其振动系统产生周期性振动的外力之源。可从公式(5)
Through the above theoretical analysis and quantitative experimental study on the vibration system of L2 series electric vibration speaker, it can be seen that the fundamental reason that caused the horn life can not pass is not the vibration system, so the electromagnetic system and relay system must be theoretically analyzed and quantified Experimental study. Third, the electromagnetic system The magnetic pulling force of the electromagnetic pulling horn electromagnet is the source of the external force of the vibration system which generates the periodic vibration. From equation (5)
