Optimization and maintenance of notebook audio system
With the improvement of notebook hardware level, notebooks have gradually reached the level of mainstream desktops in all aspects, and have begun to have the conditions to replace desktops as home entertainment centers. However, the sound system is always a "soft spot" of notebooks. Almost all notebook manufacturers use the motherboard's integrated sound card to solve the notebook's sound processing system, which makes the notebook very thin in sound, and functions such as signal-to-noise ratio and acquisition capability cannot be discussed at all. Many users who buy notebooks want to get a more perfect sound system, let the notebook become their "mobile dream theater", let me analyze the sound system of the notebook and its optimization.
Sound system: the weakness of the notebook
In the past, in notebook computers, there are several sound card chips such as ESS, AC97 and yamaha. The sound chip of ESS may be the most widely used product. However, the current new notebook audio chips all use 16-bit sampling, wavetable synthesis, 3D sound effects and other functions. Together with the high-speed PCI bus technology, they can provide fast and high-quality sound effects. The latest audio chip can make the notebook computer also output AC3 5.1 sound, which greatly improves the multimedia performance of notebook products.
But the most important reason for the poor sound quality of laptops is the problem of laptop speakers. Although the emergence of widescreen notebooks has strengthened the product's audio-visual entertainment functions, due to the limitations of the notebook's internal volume, the notebook's built-in speakers still cannot provide a higher-power sound output, and the sound quality is not satisfactory. Most low-end and wide-screen notebooks don't have a good voice, and the speakers built in the notebook will produce broken sound when it is turned on above 2/3. Such sound effects obviously cannot meet the surround sound effects of wide-screen movies. Under the premise that the sound effects of the built-in speakers are very limited, wide-screen notebook users can only use headphones to replace the speakers, which largely obliterates the true enjoyment of audio-visual entertainment.
However, notebook audio has not been valued for a long time, and most of them are regarded as speakers that can produce sound, lacking good sound quality and timbre. Now many manufacturers are trying to change this situation. For example, HP ’s COMPAQ Presario series products provide JBL Pro products of famous speaker manufacturers, which can provide high-quality and pure subwoofer effects. Many IBM ThinkPad series also have built-in Altec Lansing SoundGuide stereo speakers The sound output effect is even more unique.
However, the best way to solve the problem of poor sound effects of the laptop's built-in speakers is to expand the external speakers to achieve it, but it has some impact on portability. In fact, some optimization and maintenance of the audio system of the notebook are needed, and basically the basic daily application is still guaranteed.
Optimization and maintenance of notebook audio system
At present, the sound chip of the notebook has been done very well, thanks to the improvement of the chip integration process. There is no special need and there is no need to consider using an external high-performance sound card to improve the daily audio and video effects, the most important optimization is in the notebook built-in speakers.
Friends who often walk in the computer market generally know that notebook dealers never dare to turn the volume to the maximum when they test the machine for customers, because most notebook speakers are at the highest volume due to the limitation of rated power. Breaking sounds will occur, which will affect consumers' desire to buy. This is certainly not a bad behavior of dealers. It is true that for the built-in speaker of the notebook, the high volume is a way of leaking ugliness, and it is also an "effective method" to kill the life of the notebook speaker. Can you imagine what happens when you sing in your karaoke hall? Of course, the throat will be hurt and hoarse. So I bought a notebook, in daily applications, try not to adjust the volume to the highest volume above 2/3.
In addition, most bass sounds of notebook speakers are not good. To be more extreme, most notebook speakers are called "speakers" and are not wrong. In many sound card setup programs, you can adjust the sound effect and adjust the treble and bass. Here, it is best not to make the bass and treble too ridiculous. On the one hand, it may produce broken sound when there is no maximum volume, and then it may cause the speaker to hang up early.
Furthermore, as mentioned earlier, do not let the notebook be used in a humid and dusty environment. If the notebook speakers are mouldy or have accumulated dust due to environmental issues, the sound quality will naturally be poor. Therefore, during the warranty period, you can follow the after-sales personnel to help clean up the dust or mildew inside the notebook, or try to do it yourself after the warranty period (be careful!).
Another thing is to often go to the notebook manufacturer's website or notebook audio chip manufacturer's website, pay attention to the latest sound card driver. Generally speaking, the latest drivers will bring some optimizations and functional improvements, and also have certain benefits for the optimization of audio systems.
However, in order to get a complete improvement in audio-visual entertainment, it is best to use external speakers, and the performance of the built-in speakers is not within a level.
