Keyboard reversing - new DELL Dell silent chocolate keyboard

Nowadays, the market seems to be the world of mechanical keyboards. Everyone enjoys the kind of embarrassing feeling of mechanical keyboards. All kinds of axes are collected and used by many people. But since my son was born, things like retouching and writing originals can only be done in the middle of the night or in the early morning, because the study room and the bedroom are separated by a wall. When I type, the sounds I make will inevitably affect the poorly-worn wife. Entering a silent keyboard is a top priority. Although there is a tall commodity in the Cherry MX silent axis and silent static capacitance, as a middle-aged person who had access to a computer at the beginning of this century, after experiencing Acer 52V, BenQ Haibei, and later dell “Shenban Pan” , It has been feverish from the game, there is no such a large number of input tasks, buy an affordable film keyboard is also acceptable.

After searching the richest family, I found that DELL is the best one for me. Because of the previous work, Dell's machine was used every day. For Del L's quality control, it is still more reliable. Ever since the DELL flagship store started.

Very industrial packaging

Although the packaging is simple, there are many inside.

The chocolate keyboard, long ago, seemed to be the first to be used by the notebooks of Dafa.

How many keystrokes are raised.

With the Fn key, a multi-function layout is achieved based on the standard layout.

The blue word is the function of Fn. The actual measurement can be controlled one by one without plugging in the driver. It is very good.

A long carriage return, this is my habit, the first Philips keyboard is such a key position. I'm very uncomfortable with IBM's push-button setting.

A non-slip rubber bottom bracket allows height adjustment.

The thickness will not be excessively thin. I remember that before the ACER 52V, I started playing with the stars and hit the entire keyboard with a punch.

weight

test:

In fact, feel, conflict, nothing to test, buy it is not to do that live.

It is necessary to measure the noise:

Because it is during the day, the background noise is more than 40 decibels. The mobile phone is placed on the edge of the keyboard. Typing basically does not cause large fluctuations in the test value. You can see the volume curve. There is basically no big bump and it is relatively smooth.

The original Logitech keyboard, the same conditions, more than DELl 20 decibels, the second half of the curve is raised, is the key to the sound.

DELL this keyboard, while ensuring a certain feeling, while achieving a mute effect, when typing is basically no more than 50 decibels, which means that there will be no interference to others. Writing in the middle of the night will no longer disturb his wife and children, perfect for purchase.

The general concept of sound size:

90 decibel noisy bar environment sound

85 decibels or less will not damage the cochlea's hair cells. The best sound should not exceed 80 decibels.

80 decibels are noisy

75dB human ear comfort ceiling

70dB street environment sound

50 dB normal conversation sound

Thanks to the large quantities of DELL, the cost of the keyboard can be well controlled. The price of the DELL official Tmall shop 60 black can be said to be very cheap (the price of the tb shop is lower), even if the film keyboard has a short life It does not feel bad to replace it.

There is the keyboard feel actually pretty good, and laptop, desktop ordinary keyboard alternately use there is no big problem. If there is a need for keyboard mute, and the budget is not enough, this DELL is a good solution.
