What should I do if the voice control light doesn't work well?

First of all, this lamp has a voice-activated sensor (vibration sensor). When there is sound (vibration), the sensor sends out an electrical signal (current). This current then triggers the time delay relay. The relay opens the lighting circuit. By time delay relay's time (magnetism disappears), the lights go out.
