| 中文摘要: |
| 力学非线性和磁场非线性是扬声器非线性现象的两个因素。本文分析了仅力学非线性的扬声器低频振动方程的临界跳变条件,采用等效线性化法讨论了磁场非线性对扬声器跳变的影响,证实了抑制扬声器跳变的有效途径是增大电磁耦合因子B1。 |
| 英文摘要: |
| Mechanical nonlinearity and magnetic nonlinearity are two factors that cause nonlinear phenomena in a loudspeaker. This paper analyzes the critical situation on condition of mechanical nonlinearity only, discusses the influence of magnetic nonlinearity on jump in loudspeaker using the method of equivalent linearization, and confirms that an effective method to reject jump in a loudspeaker is to increase the value of the elec-tromagnetism coupling factor B1. |
