How to cook headphones?

Most car owners have the experience of running in a new car. What is running in? Audio jargon-"package" also. There are strict rules for running-in of cars, and the engine should idle.

How many hours, first gear, second gear, third gear ... how many kilometers, and so on. In order to limit the output of new cars, some have installed speed limiters.

Control the air volume into the cylinder, so that you can't think fast, and you can only fold it after running in. When you change the oil at the end of running-in, you will find that.

Now, son! It turns out that there are so many beaten soldiers and metal scraps in this oil that you are completely scared.

The running-in quality of cars has a great influence on the future output and service life, so experienced people will extend the running-in period. Hometown of steel

At first, we have to wait like this. Think about our audio equipment, especially our exquisite headphones. How should we cook them?

Headphones are mainly the diaphragm of headphones. At present, the diaphragm thickness of electrostatic headphones is as thin as 1.35 micron, and the diaphragm of dynamic headphones is only a few microns.

To more than ten microns (the diameter of our hair is about 60 ~ 90 microns). The diaphragm itself has internal stress in the manufacturing process, so it is difficult to bond and fix the voice coil.

When the frame is opened, the assembly stress reappears. The earphone pot we are talking about is the process of making these stresses disappear gradually, making the diaphragm smooth gradually and making a good sound.

I often see some Hi-Fi master's equipment audition reports, some of which are high or low, and I don't comment, but most of them started from boiling the equipment at full speed for three days.

Three nights, let it suffer the pain of flesh and blood, think it is in a good situation, and then how to make a good comment. The method of cooking machines came into being for a long time.

There are countless imitators. This will not be afraid of damaging the equipment, falling into hidden dangers, and the sound is not long!

I thought that although the audio equipment was neither a construction machine nor an iron car, there were similarities. Good things should be ground more and cooked slowly to make a good sound! The cooking machine is still smooth and smooth.

The five steps of winding, practicing martial arts, beating and debut are better. Take headphones as an example:

1, relax muscles and activate collaterals-drive the earphone 12 hours at a volume one third of the normal listening intensity (it is best to use 100 ~ 15000 Hz/5s sweep signal);

2. Communication-drive the earphone 12 hours at two-thirds of the normal listening intensity (it is best to use 50 ~ 18000 Hz/3s sweep signal);

3. Practicing martial arts-driving headphones for 72 hours with normal listening intensity (it is best to use 20 ~ 20 ~ 20~20000Hz/2s sweep signal);

4. Jumping-drive the earphone for 24 hours at a volume of four-thirds of the normal listening intensity (it is best to use the sweep signal of 18 ~ 22000 Hz/ 1s);

5, debut-enter the normal use stage.

I think this method has at least two advantages. First, you can understand the law of sound quality changes in various stages of the machine, understand the role of the machine and accumulate experience; second

It can improve the performance of the equipment, leave no hidden danger and prolong the service life of the equipment.

Writing here, I can't help but think of a sentence from the great detective Poirot in the movie Nile Massacre: "Take it easy, police officer!" " .

I gave my brothers a present when I first appeared. I hope you can download it. Absolutely easy to use! ! !

That's how you cook. Don't turn up the volume too loud. The new headphones are tight. Too loud can easily damage them.

Newly bought headphones, the diaphragm has not been "moved", and the folding ring of the diaphragm is relatively hard. At this time, when listening with headphones, the sound pressure of the whole frequency will be lower than the nominal value, especially in

The sensitivity of high frequency band and low frequency band (this is only relative) is also lower than the nominal. At this time, the headphones will have poor extension of high and low tones, poor sense of volume, and the sound field will not be opened.

Let go, the details are not rich and clear. How to deal with it? -"bag"

How to cook? Connect the audio source, put on the record, turn it on, and talk to him day and night for XX hours. All right! ! ! is it

Is it wrong to cook headphones with music? Because the frequencies contained in music are quite rich, each frequency band has considerable energy ... In the middle and high frequency bands, the diaphragm has less exercise.

That's just massage headphones. "Potting" is to make headphones work as soon as possible. Putting audio on headphones is like Chinese medicine. Although it has a comprehensive effect, it is relatively slow.

After this principle, the small one is written down as follows:

Use a transformer, the number of W is not limited, the secondary voltage is 6V AC, and take a variable resistor (material is not limited) above 5K/2W, and then make both headphones have high resistance according to the impedance of headphones.

Parallel connection, low resistance series connection, then series connection with the front 5K resistor, connected with 6V AC power supply, and then adjust 5K resistor to make the volume moderate. ...

This method is to cook headphones with a low frequency signal of 50HZ. This method can make the earphone diaphragm fully move and make the earphone mature faster. However, pay attention when cooking.

It means the following three points:

Before connecting 1 5K resistor, it must be at 5K terminal. If the connection is wrong, the AC signal will be directly added to the earphone, which is in danger of burning the earphone. High resistance is no problem, low resistance is ten.

Nine times out of ten, it's over. ...

2. Don't turn up the volume of headphones too much. The impedance of earphone in low frequency band is much lower than the nominal value, and the sensitivity of human ear to low frequency is weaker than that of intermediate frequency, such as

If the volume is adjusted as loud as the 1KHZ signal, the power borne by the earphone is at least twice that of the 1KHZ signal with the same volume ... Be careful.

Machine! ! ! ! !

Headphones should rest every hour. This is mainly to make the heat generated by the earphone voice coil when passing through low-frequency signals be fully radiated. ..

If it is a continuous cooker with high power, the accumulated heat is likely to melt the sealant on the voice coil. At this time, this earphone is always a little crosstalk when listening.

Voice-over ",did you feel bad at that time? Pain? Scold me? Still puzzling?

That's what my 240M is doing ... After cooking, the sound of 240m is clearer, purer and richer in details, and the overall beauty is pleasing to the eye. High frequency crystal clear, enduring.

Extending to the distance ... the low frequency is tepid, the sense of volume is slightly increased, the dive is obviously deeper than before, the speed is much faster, it is elastic, fast enough and strong enough. The sound of it.

I am also more confident than before, and my voice is more cordial and lasting, with a sense of whispering, gentleness and warmth.

The audition disc is

The first song is my favorite song. The 57-second triangle is brittle and extends for a long time. It makes people feel gloomy.

I found a glimmer of hope in the music .. The sound of bangzi in the fifth song is concentrated and penetrating. ....

& lthi-fi >； The presented CD consists of two songs, one is drum music and the other is female chorus. ..

This is a pure drum music, full of movement, with a strong sense of energy and oppression. The dive of the low drum is deep, powerful and elastic, and the reverberation of the drum is very clear.

Obviously, the arrangement of the whole drum array is recorded very accurately, which is a weapon for testing low frequency! ! ! !

The second female chorus, the most prominent thing is that her sound stage is very grand, and there is a wonderful female voice floating gently in the faint music. Please keep warm and natural. Listen.

At that time, I could accurately hear the position of each part of the female voice, and the singer's breathing was also very clear, which was debatable. The recording is really admirable! ! !

These two records are the ones I use the most. Their recording effects are not butterflies, but I am familiar with them. I can audition with them well.

Don't talk about the difference in equipment, I think this is the most important thing. The audition disc is good, but the most important thing is that it must be music you are familiar with and love.

I'm not familiar with the dishes I don't like, and I don't know what I'm talking about! ! ! !

When making baskets, it is important to collect them. In fact, I have written this article for a long time, so I haven't published it, mainly because I just came to the forum and have more personal skills.

There are shortcomings, poor writing, and fear of posting jokes. Today, I also dare to fight for my luggage. If there are any shortcomings, please advise. If there are any mistakes, please advise.

In line with the principle of mutual exchange and learning, please give us more valuable opinions! ! ! !

Introduction:

Everyone who can cook knows that the dishes stewed by small fire are delicious. In fact, many things are like this. After all, many things grind people. The word "bag" is not only used by chefs, but is familiar to almost all audio lovers. Whether it's a CD player, a power amplifier or a newly bought speaker, in short, you can't make a good sound without cooking. However, for multimedia audio enthusiasts, the requirements for box making seem to be much lower. However, with the listing of a large number of high-end speakers represented by M200, box-making has been talked about by more and more fans.

Anyone who has made a speaker knows that this is a long process, but later a software "Baby Boiling Box" seems to have solved such a difficult problem. After many users' use, this software is not as beautiful as everyone imagined. On the contrary, due to improper operation, many users' speakers have been damaged to varying degrees, which has to be said to be not worth the candle. That is, since then, many users have opposed the software that makes boxes. However, today, I still want to introduce a box-making software, the rambler's box-making tool, which was launched by domestic multimedia audio rambler.

First of all, we want to explain that although this software is produced by rambler, it is suitable for all speaker brands, which means that all speakers can cook quickly with this software.

The interface of the software is very fresh. After starting the software, we will first see the introduction of why and how to cook the box. Click the "Next" button in the lower right corner to enter the next link.

In this page, we can adjust the volume of the box. The software gives four choices from 0dB to-12 dB * *, but for safety reasons, the software suggests that you choose -6 dB signal as the box. It should be noted that the signal of the cabinet is pink noise with two channels and opposite directions. It is necessary to place two speakers face to face and use the opposite directions to eliminate the noise.

Pink noise is the most common noise in nature. Simply put, the frequency component power of pink noise is mainly distributed in the middle and low frequency bands. From the waveform, pink noise is fractal, and audio data has the same or similar energy in a certain range. In terms of power (energy), the energy of pink noise decreases from low frequency to high frequency, and the curve is 1/f, usually decreasing by 3 decibels every 8 degrees. Pink noise is the most commonly used sound in acoustic testing.

This is an option about filling time, and the recommended time is 3 hours.

The software also has the function of what the computer will do after unpacking, and we can make corresponding choices according to our actual situation.

The last item is to start cooking. At this time, we will hear a low-volume "rustling" sound, which is the pink noise mentioned above.

We will also see another option in the software, namely the signal generator. Compared with other signal generation software, the signal accuracy of the signal generator included in this software has been greatly improved. This is because most sound cards sold in the market now have serious SRC problems, which makes it difficult for these sound cards to send out really correct signals at the sampling rate of 44. 1kHz. Therefore, the rambler tool sets the sampling rate of the signal to 48kHz, which greatly improves the accuracy of the signal. We see that this signal generator provides three waveforms, namely sine wave, triangle wave and square wave. Users who have studied related subjects will naturally know their differences, while ordinary users will know them at will. Signal types also include single frequency and scanning signals.

If "Scan Signal" is selected in "Signal Type", there will be two options for users to choose which scanning method to adopt. The following options are for users to adjust other details, and we can monitor the changes between various signals in real time.

Generally speaking, the operation of this software is quite simple and easy, and basically it will not damage the audio equipment because of improper operation. So, if you want to get through the cooking process of your own speaker quickly, I believe this software can help you a lot, but what we want to say is that music playing is still an indispensable part of the cooking process.
