Thanks to the rapid growth of the overall economy in recent years, the sales of sedans in China have also been increasing year by year. With this trend becoming increasingly prominent, many car enthusiasts have a growing demand for other functions of their cars, such as car audio modification, which has been increasingly favored by these enthusiasts in recent years. It is precisely under the influence of this demand that, Now the intelligent Bluetooth shoe light industry has also ushered in a new round of development. As is well known, there are many considerations when modifying car audio systems. Therefore, today, the intelligent Bluetooth shoe light will talk about how to know the resonant frequency of the speaker when modifying car audio systems.

In a circuit containing capacitors and inductors, if the capacitors and inductors are connected in parallel, it may occur during a very short period of time: the voltage of the capacitors gradually increases while the current gradually decreases; At the same time, the current of the inductor gradually increases, while the voltage of the inductor gradually decreases. And in another very short period of time: the voltage of the capacitor gradually decreases, while the current gradually increases; At the same time, the current of the inductor gradually decreases, while the voltage of the inductor gradually increases. The addition of voltage can reach a positive value, and the decrease of voltage can also reach a negative value. Similarly, the direction of current will also change in the positive and negative directions during this process, which is called electrical vibration in the circuit. The phenomenon of circuit vibration may gradually disappear, or it may continue to remain unchanged. When the oscillation continues to persist, we call it constant amplitude vibration, also known as resonance.
