What is the role of Faraday capacitors in sound systems?

How important is the car Faraday capacitor for car audio? Perhaps readers only know about the large capacitors installed on the power supply end of the audio system with a voltmeter attached, but in fact, capacitors are the basic components of electrical appliances, including the main unit, front stage, power amplifier, and even passive splitters of speakers. Various specifications and constructions of capacitors are everywhere, and their importance is evident! However, due to the difficulty of electrical theory, we will only briefly introduce the principle of the operation of automotive Faraday capacitors at the power supply end and the improvement of audio performance through the use of capacitors to manipulate small hands and feet. We hope to provide a clearer understanding of the use of automotive Faraday capacitors. 

The car Farad capacitor, which has a long lifespan and can quickly charge and discharge currents, is used in the power supply of car audio systems. As the name suggests, it is something that seems to be able to accommodate current. To put it simply, if the car generator and battery are treated as the source of a river, the current is treated as a river, and the power amplifier is treated as a water wheel that operates using the river, then the car Farad capacitor is like a lake between the source and the water wheel. When the water wheel works inefficiently, the normal flow of the river water can handle the driving water wheel, but when the water wheel needs to operate quickly under heavy load, the water flow from the source of the river water often exceeds the supply and even cannot carry the water wheel. Build a lake between the sources, and when the water from the source cannot drive the water wheel, use the pre stored water in the lake to quickly replenish it, which can maintain the operational efficiency of the water wheel. This is the role of the car Farad capacitor! At this point, if we are in the water wheel and in addition, the Faraday capacitor of the car has the characteristic of long lifespan and fast charging and discharging speed. When the power amplifier operates under high load, the instantaneous current is quite large. At the same time, the car generator and battery may not be able to supply electricity in a timely manner, resulting in a decrease in the operational efficiency of the power amplifier and a decrease in sound quality. But if fast charging and discharging car Faraday capacitors are added, when the power amplifier needs a large amount of electricity in an instant, it can maintain a stable power supply for the amplifier when the generator and battery are unable to supply power in time, and then quickly fill up the power from the generator end, preparing for the next "impulse" (power amplification output).

Compared with ordinary secondary batteries, super large capacity batteries can carry out high current charging and discharging, making them a battery with excellent charging and discharging cycle life. In recent years, energy issues such as reducing oil and electricity consumption (reducing the effective utilization of new energy) have received great attention. Currently, discussions are underway to equip new applications with ultra large capacity. In addition, discussions on the use of ultra large capacity for efficient energy utilization in hybrid vehicles and fuel cell vehicles are also accelerating.Actively developing energy-saving and environmental load reducing products, among which ultra large capacity is a representative environmentally friendly corresponding product, providing a variety of specifications of large capacity products from 1F to 3200F and above.
