How to burn in the Meizu headset EP10?

Every car owner has the experience of running in a new car. What is running in? Audio lingo - "Pot". There are strict regulations for the running-in of a car, including how many hours the engine needs to be idling, how many kilometers it needs to be driven in first gear, second gear, third gear... and so on. In order to limit the output of new cars, some even install a speed limiter, which limits the amount of gas entering the cylinder, making it impossible to go faster even if you want to. It can only be removed after running in. When you change the oil after running in, you will find out, good guy! It turns out that there are so many remnants and metal debris in the oil, which is enough to scare you.

The running-in quality of the car has a great impact on the future output and lifespan, so anyone with experience will extend the running-in period. This man of steel and iron had to be treated like this at first. Think about it, how should we cook our audio equipment, especially our delicate headphones?

The main purpose of burning headphones is to burn the diaphragm of the headphones. At present, the thickness of the diaphragm of electrostatic headphones has been as thin as 1.35 microns, and the diaphragm of dynamic headphones is only a few microns

To more than ten microns (the diameter of our hair is about 60 to 90 microns). The diaphragm itself has internal stress during the manufacturing process, and assembly stress is generated when the voice coil is bonded and fixed to the skeleton. What we call "burning in headphones" is to gradually eliminate these stresses and make the diaphragm The diaphragm gradually adapts to the process of producing good sound.

I often see the equipment trial reports of some Hi-Fi masters. I don’t comment on the level of the equipment, but most of them start with the equipment being turned on at full power for three days.

For three nights, let him suffer all kinds of physical and physical pain, thinking that he was in a good state, and then he made some nice comments. This is how the method of cooking for a long time was born, and countless people imitated it. In this way, you are not afraid of damaging the equipment and leaving hidden dangers, and the good news will not last long!

I think that although audio equipment is not engineering machinery or iron cars and horses, there are similarities. Good things take time, slow cooking will produce good results! It is better to break the machine into five steps: relaxing the muscles, clearing the collaterals, practicing martial arts, fighting, and making a debut. Take headphones as an example:

1. Relax your muscles—use one-third of the normal listening intensity to drive the headphones for 12 hours (it is better to use a 100~15000Hz/5s sweep signal);

2. Tongluo - use two-thirds of the normal listening intensity to drive the headphones for 12 hours (it is better to use a 50-18000Hz/3s sweep signal);

3. Martial Arts ——Use normal listening intensity to drive the headphones for 72 hours (it is better to use 20~20000Hz/2s sweep signal);

4. DaLei——Use 3/4 of the normal listening intensity to drive the earphones. Headphones for 24 hours (it is better to use 18~22000Hz/1s sweep signal);

5. Debut - enter the normal use stage.

I think this burn-in method has at least two major benefits. First, you can understand the rules of sound quality changes at each stage of burn-in, understand the role of burn-in, and accumulate experience; second,

It can improve equipment performance and extend equipment life without leaving any hidden dangers.

Writing this, I can’t help but think of the words of the great detective Poirot in the movie "Tragedy on the Nile": "Take it easy!"

This is my first appearance to give all brothers a meeting gift. I hope you can download it, it will definitely be very useful! ! !

This is how to cook. Never turn up the volume too high. New headphones are tight and can easily be damaged if they are too loud.

The diaphragms of newly purchased headphones are not made. After "exercise", the ring of the diaphragm is harder. When listening to the headphones, the sound pressure of the entire frequency response will be lower than the nominal value, especially in the high frequency band and low frequency band (this Only relative), the sensitivity is also lower than the nominal. At this time, when listening to the headphones, the high and low frequencies are not extended well, the sense of volume is poor, the sound field is not widened

, and the details are not rich and clear enough. How to deal with it? -----"Pot"

How to cook it? Connect the audio source, put on the record, turn it on to a loud blast, come to him day and night, and continue to cook XX- Hours, okay!!! Is it right?

Isn’t it inappropriate to use music to burn headphones? Since music contains quite a lot of frequencies, each frequency band has considerable energy.. In the middle and high frequency bands, the diaphragm The amount of exercise is small,

It is just massaging the headphones. "Boiling" is to get the headphones into working condition as soon as possible. Using audio to cook the headphones is like traditional Chinese medicine. Although it has comprehensive effects, it is slow. In the spirit of first

Based on this principle, the following is a small formula, as follows:

Use a transformer, the number of W is not limited, the secondary voltage is 6V AC, take a 5K /2W or above variable resistor (material is not limited), and then according to the impedance of the earphones, connect the two earphones with high impedance

in parallel and low impedance in series, then connect them in series with the previous 5K resistor, and connect to the 6V AC power supply , and then adjust the 5K resistor to make the volume moderate...

This method is to use a 50HZ low-frequency signal to cook the earphones. This method can make the earphone diaphragm fully move, and the earphones will mature faster. .However, you should pay attention to the following three points when cooking:

1. Before connecting the 5K resistor to the circuit, it must be at the 5K end. If it is connected incorrectly, the AC signal will directly If you add it to headphones, there is a risk of burning them. High impedance is fine, but low impedance will finish the game nine times out of ten

...

2. Don’t turn up the headphone volume too high. Large. The impedance of headphones in the low frequency band is much lower than the nominal value. In addition, the sensitivity of the human ear to low frequencies is weaker than that of mid frequencies. If the volume is turned up to be consistent with the 1KHZ signal If the volume is the same, the power the earphones bear is at least twice that of the 1KHZ signal with the same volume. Be careful with your ears

!!!!

3. The earphones are burned every time After an hour, you should take a break. This is mainly to allow the heat generated by the earphone voice coil to fully dissipate when it passes through the low-frequency signal.

If it is a continuous cooker and high power, heat accumulation It is very likely that the sealant on the voice coil will melt. At this time, when listening to the earphone, there will always be a little "string

outside sound". At that time, you will feel uncomfortable? Painful? Cursed Me? Still confused?

This is how my 240M was cooked. After the 240M was cooked, the sound was clearer, pure, richer in details, and overall clear and pleasant. The high frequency was crystal clear and extended.

Zhan Youyuan.. The low frequency is tepid, the sense of volume has increased slightly, the dive is obviously deeper than before, and the speed is also much faster. It is elastic, fast and powerful. Its vocals

I am more confident than before, and my voice is more friendly and durable, with a whispering feel, gentle and warm ``````

For the audition disc It is the first and fifth songs of lt;Sad Citygt;, and there is a CD given by lt;Hi-Fi gt;

The first song of lt;Sad Citygt; is my favorite One of my favorite songs. The triangle sound at 57 seconds is extremely crisp and long-lasting. Listening to this sound makes people find a glimmer of hope in the gloomy music.. The fifth song The sound of the clapper has concentrated energy and is very penetrating....

lt; Hi-Fi Sound gt; The complimentary CD has only two songs, one is a drum music and the other is a female chorus. .

This is a pure drum music with great dynamics and energy.

There is a strong sense of pressure, the bass drum dives deep and powerful, and is full of elasticity. The drum's reverberation is very clear

The arrangement of the entire drum array is recorded very accurately. It is a sharp tool for testing low frequencies!! !!

The second female chorus, the most outstanding thing is that her sound field is very grand, and the delicate female voice floats gently in the faint music, which is warm and feels like nature. Listen to the music

When recording, I can accurately hear the position of each part of the female voice, and the singer’s breathing sound is also clear and distinguishable. The recording is really impressive!!!

These two pictures Records are what I use most, and their recording effects are not as good as Tiandie, but I am very familiar with them, and I can distinguish the equipment very well by using them for sound check.

I think this is the most important difference. As for the audition disc, Tiandish is good, but the most important thing is that it has to be music that you are familiar with and passionate about.

Not familiar with it? I don’t know what I like about the dishes I listen to!!!!

When weaving baskets and making baskets, the most important thing is to close the ends. In fact, I have written this article a long time ago, so I have not published it for a long time. I just came to the forum not long ago, and I have a lot of personal skills.

I have some shortcomings, and my writing style is poor. I am afraid that it will make everyone laugh. Today I am also bold and burdensome. If there are any shortcomings, please let me know. Please give me your advice if I am wrong.

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

Introduction:

Everyone who can cook knows this The principle of slow simmering over low heat creates delicious food. In fact, this is true for many things. After all, good things take their time. The word "cook" is not only used by kitchen masters, almost all audio enthusiasts will be familiar with this word. Whether it’s a CD player, an amplifier, or a newly purchased speaker, in a nutshell, it’s not enough to produce good sound without burning it. But for multimedia audio enthusiasts, the requirements for burner speakers seem to be much lower. However, with the launch of a large number of high-end speakers represented by M200, burner speakers are also talked about by more and more enthusiasts.

Anyone who has tried to use a speaker knows that it is a long process, but then a software "Baby Box Baby" appeared that seemed to solve such a problem. After being used by many users, this software is not as good as everyone originally imagined. On the contrary, due to improper operation, many users' speakers have been damaged to varying degrees. It has to be said that the gain outweighs the loss. That is, since that time, many users have opposed the box-burning software. But today we still want to introduce to you a box cooking software "Edifier Box Cooking Tool", a box cooking software launched by the domestic multimedia audio leader Edifier.

First of all, we have to explain that although this is a software produced by Edifier, it is suitable for all speaker brands, which means that all speakers can use this software to quickly of claypot.

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

On this page, we can adjust the volume when the box is boiling. The software gives four options from 0dB to -12dB***, but for safety reasons, the software recommends that you use a -6dB signal for box boiling. It should be noted that the signal from the burner box is two-channel and mutually inverted pink noise, so the two speakers need to be placed face to face to eliminate the noise by using mutual inversion.

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 a waveform perspective, pink noise is fractal, and the audio data has the same or similar energy within a certain range. From a power (energy) perspective, the energy of pink noise continuously attenuates from low frequency to high frequency, with a curve of 1/f, usually 3 decibels for every 8 degrees. Pink noise is the sound most commonly used for acoustic testing.

This is an option about the cooking time. The recommended time by the software is 3 hours.

The software also has the function of what operations the computer will perform after the oven is finished. We can make corresponding choices based on our actual situation.

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

In the software we will also see another option, which is the signal generator. Compared with other signal generation software, the signal accuracy of the signal generator included in this software is much improved. This is because most of the sound cards currently sold on the market have serious SRC problems, which makes it difficult for these sound cards to send truly correct signals at the sampling rate of 44.1kHz. Therefore, the Edifier Box Mixing Tool changes the signal sampling rate to Set 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 it at a glance. Signal types also include single frequency and scanning signals.

If you select scanning signal in the signal type, there will be two more options for the user to choose which scanning method to use. The following options allow users to make other detailed adjustments, and we can monitor the changes between various signals in real time.

In general, the operation of this software is quite simple and easy, and there is basically no damage to the audio equipment caused by improper operation, so if you want to quickly get through the problem of your speakers I believe this software can help you a lot during the cooking process, but what we want to say is that music playback is still an indispensable part of the cooking process.
