Description

The present invention relates to a notebook computer equipped with a sound equalizer, and in particular, a light emitting diode is installed on the notebook computer, and the light emitting diode blinks according to the volume level, the rhythm intensity, and the operating temperature of the central processing unit. The present invention relates to a notebook computer equipped with a sound equalizer that produces a change.

With the advancement and development of technology, notebook computers have made great progress.
The progress is not only faster and more capacity, but also significantly reduced in volume, making it very light and compact and convenient to carry.
And more importantly, the price has become reasonable, allowing many to own notebook computers.
As a result, notebook computers have recently become a major replacement for desktop computers.

However, many notebook computer manufacturers are now focused on how to express better sound quality, neglecting the convenience of consumer use, and the effects of consumer sound and light. It is easy to forget to meet the demands for
In the current notebook computer, the user cannot know the current volume level from the appearance of the notebook computer, but the volume can be adjusted only by the volume display on the screen while adjusting the volume with the button. Can not.
This makes it look monotonous and uninteresting, and consumers can't figure out how loud the sound is at a glance. There are often situations where it is emitted at a volume and bothers the user or the surrounding people.

In particular, if a user is in a place that must always be quiet, such as a hospital or a library, if suddenly a loud sound or other sound is emitted, not only will he be surprised by the surroundings, but the work of others It becomes an obstacle to studying and it becomes a serious difficulty for the user.
Many of such sounds cannot be anticipated by the user himself. For example, an advertisement video may be played on the top page of a net shop.
These videos are automatically played as soon as you enter the site, and some personal blogs have MP3 files of music you like. It will be automatically played immediately.
In other words, with conventional products, it is impossible to judge the volume level at a glance, so you forget to adjust the volume, and a very loud sound is suddenly emitted, causing inconvenience and trouble for the user and the surrounding people. Things often happen.

By the way, although the performance of the central processing unit of the notebook computer continues to improve, there is a problem that the operating temperature rises accordingly.
Certainly, various heat dissipation fans and heat dissipation technologies can effectively mitigate the rise in temperature and control them within a certain acceptable range. It gradually decreases as it gets longer.
For example, if dust accumulates on the radiating fins, the inlet / outlet vents, or the radiating fan, the normal operation of the radiating fan is affected, and hot air cannot be effectively discharged.
Furthermore, there is a possibility that the heat dissipating fan cannot operate normally due to the durability of the heat dissipating fan's bearings, which makes it impossible to control the operating temperature of the central processing unit within the normal operating temperature, resulting in freezing. There is a possibility.

In order to cope with these situations, there is a method of monitoring the operating status of the notebook computer using monitoring software, in addition to the user periodically performing cleaning work.
However, the current monitoring software cannot perform the monitoring operation of the data of related parts unless the user activates the monitoring software.
That is, since it is passive activation as described above, it is difficult for the user to grasp the situation immediately, and usually the situation is abnormal in the operation of the notebook computer (for example, the execution speed becomes slow or freezes). This is the situation where the monitoring software is started, each part is monitored, and the location of the problem is searched for.
Therefore, it may be too late in terms of timing, and since it is a situation where a doctor is consulted after getting sick, it is possible to prevent abnormalities such as immediately discovering abnormalities and proactively treating them with a method of receiving a health checkup. Cannot be expected.
