Application of crystal oscillators in various audio systems [Copy link]

In an increasingly impetuous society, many people like to relax themselves in the world of music, and owning a good playback device must be the dream of many music lovers.

Everyone knows that music has many magical functions, such as distracting attention, relaxing the body, and good music can relieve stress and avoid chronic diseases caused by autonomic nervous system disorders. It can eliminate fatigue, cultivate people's sentiments, and improve physical and mental health. If you have a good speaker, then these magical functions of music must be twice the result with half the effort.

When it comes to audio, we have to mention crystal oscillators. A good audio system cannot be without a high-quality crystal oscillator. So what is the relationship between crystal oscillators and audio systems?

Crystal oscillator , although small, has powerful functions. The crystal oscillator used in the audio system is different for different audio types. The more commonly used ones are 3.2 X 2.5 chip crystal oscillators, and the general plug-in audio system special crystal oscillators are 49S crystal oscillators and cylindrical plug-in crystals. Common frequencies are: 32.768KHz, 3.57954MHz, 12MHz, 16MHz, 24MHz, etc. The crystal oscillators used in car audio are 12MHz and 24MHz, and the car audio system also uses a clock crystal oscillator of 32.768KHz. The crystal oscillators used in speakers and subwoofers are generally 32.768KHz, and the crystal oscillators and the audio motherboard are equipped with active crystal oscillator patches of 5.0 X 7.0mm temperature compensated crystal oscillators.
The key to the sound quality of the audio system is the accuracy of the crystal oscillator. As the name suggests, the higher the crystal oscillator accuracy, the better the sound quality of the audio system. Just like the 32.768KHz crystal oscillator used in all clock products , its accuracy directly affects the accuracy of time.
