How does the sound work?

　　It is to amplify various sound signals played by the audio source to push the speaker to produce sound. From a technical point of view, the power amplifier is like a current modulator, which converts alternating current into direct current, and then is controlled by the sound signal played by the audio source, and transmits currents of different sizes to the speakers according to different frequencies, so that the speakers emit corresponding sizes. , the corresponding frequency sound.

　　Sound refers to sounds other than human language and music, including sounds of the natural environment, sounds of animals, sounds of machine tools, and various sounds made by human actions.

　　Audio probably includes a set of power amplifiers, peripheral equipment (including compressors, effects, equalizers, VCDs, DVDs, etc.), speakers (speakers, speakers), mixers, microphones, display devices, etc. Among them, speakers are sound output devices, speakers, subwoofers, and so on.

　　A speaker includes high, low and medium speakers, three but not necessarily only three. The development history of technology can be divided into four stages: electron tubes, transistors, integrated circuits, and field effect tubes.

　　To be precise, it is an integrated audio set machine launched by the manufacturer, which has as complete a function as possible, is easy to use, and has a gorgeous appearance. All the components of the sound combination, such as speakers, power amplifiers, decks, and CD holders, are provided by one manufacturer. It takes a lot of time to debug. Generally speaking, it can be used directly, which is more convenient in operation and more complete in functionality.

　　Many people think that the quality of the combined sound is not high, but in fact, with the development of electronic technology, the performance of the combined sound has also been greatly improved, so for most users, it can fully meet the needs. Of course, there is also a huge gap in the price, quality and performance of the combined audio system. There are products with a thousand yuan level and tens of thousands of dollars. Which one is needed can be completely selected according to the user's own economic strength and needs.
