摘要: | The present invention compensates bass frequency for a loudspeaker without using any sensor. The strength and stability of the loudspeaker are enhanced and the working frequency is lowered too. Adaptive loudnesses for various spaces are set. And the parameter drift owing to long-term operation is restrained as well. |
