How to cook headphones?

Do you want to boil the headphones? I think if you are not in a hurry, you will get into the state after listening for a while.

For the method of cooking headphones, please refer to the sound box. . . (omitted)

I have some questions about headphones. The newly-opened HD600 sounds stiff, and the high notes are not as crisp as expected. After listening for a few days, I feel much better. feel

Headphones have been released a lot. The question is whether the earphone has been cooked or my ears have adapted to it.

Play CD or FM repeatedly at a higher volume (the maximum volume you can bear) for three days and three nights in a row.

Better plug it in the radio! Turn up the volume, but not too loud, so as not to damage the headphones. Let it go for three days and nights! If you feel noisy, wrap your clothes!

Find a sound source, turn it to the right volume or a little louder, and play it continuously for dozens of hours. I usually use the radio.

I don't think it's necessary to keep mentioning the boiler. In fact, it seems better to let the machine wear naturally. If you have to cook, it seems that there are generally two ways:

1. Play blank noise for at least 32 hours. If there is no blank noise source, play the radio.

2。 It takes about 32 hours to play intermediate frequency music on a CD player.

It depends on personal preference!

The easiest way to cook headphones:

Find a radio with a headphone jack, turn the radio to a place where there is no signal, and plug in headphones.

TV

Just ordinary music, preferably rich in content, and the radio can also be used. Use the normal volume when cooking, or speak louder, not too loudly, every time you cook.

A few hours, the headphones need to rest for a while.

If you don't have a stereo radio, it's the same to use other audio sources, such as a cd player, which has strong low-frequency dynamics and can be played repeatedly.

My own understanding of what cooking headphones are is that it is mainly a rapid aging process of the mechanical system of headphones and the sound of mobile headphones.

The diaphragm is driven by the voice coil, and the diaphragm is fixed on the shelf of the earphone. Theoretically, the diaphragm motion should be the piston (vertical) motion.

The edge of the diaphragm needs to be more flexible, which is where the pot is. The edge of the diaphragm of the new earphone is tight, with high elasticity and low compliance. Pots are made.

On the edge of the activity, the sound is not so tight.

It should be noted here that the fixation of various parts of earphone pronunciation is glued together, so whether it is used in a pot or at ordinary times, it is necessary to maintain a certain volume.

On the box, firstly, although the current bonding technology has ensured considerable strength, under normal circumstances, the voice coil will not be shocked and the diaphragm will be stuck, but in case it appears.

Irretrievable loss; Secondly, the moving range of the diaphragm is limited. Normally, it works in the linear range to ensure low enough distortion.

Beyond this range, any distortion of headphones will make you unacceptable.

So I think one is to have a certain volume, which is basically the volume when the ears can't stand it, but it can't be too big; The second is to ensure a certain continuous time; Third, such as

If you don't want to get old quickly, you don't have to cook.

Personally, I spent three hours on discman when cooking k50 1. A friend said it would last at least ten years, but apparently he didn't.

Understand the principle of "pot".

Old dog

Slow down the sound, slow down the sound.

The topic of cooking machine has a long history, and there are different opinions, each with its own theory. Why did the old dog come to such a topic the first time he sent it? Really have the suspicion of "old millet rotten chaff", no

New wine in old bottles has existed since ancient times. You might as well drink three cups and taste a different taste.

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.

Talking about "Bao" headphones

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. For example,

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 always has 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, 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, we also dare to fight and dare to carry heavy burdens. If there are any shortcomings, please give me more advice and hope to correct me.
