I know that magnets are not good for computers, but aren t there magnets in the speakers?

Magnets have an impact on the computer, but the magnets in the speaker have no effect, because the speakers are shielded.

The degaussing I am talking about here is mainly for the speaker voice coil. Why does the speaker voice coil become magnetized? Because of the speaker voice coil and skeleton, some materials like lacquer are used.

Although these materials are very small in amounts, they still contain a certain amount of iron. The power amplifiers we use, especially the transistor power amplifiers, although the output is AC signal, there will be more or less a certain DC component. When these irons encounter direct current, they will be magnetized, which will affect the replay effect.

First, prepare a CD with audio signals of each frequency. Some high-end speakers come with an audio test disc that can be used. Put this CD in your CD player, set the 100Hz audio track first, and use the continuous replay function on the CD player to select points A and B so that it can be continuous for **30 seconds.

The sound field of the degaussing speaker is much calmer than that of the non-demagnetized, and the background will be much cleaner. There will be a noticeable improvement in the overall effect. I recommend that you demagnetize once every one to two months.

When you learn about electromagnetism in high school, you'll know.

Kiss. Hello, I'm glad to answer for you: Is the louder the speaker's magnet, the safer it is?

Hello dear, the magnet behind the horn produces the basic condition of electromagnetic (magnetic field) size, the larger the magnet, the higher the voltage, the louder the sound. It's not that bigger is better, but that the stronger the magnetism, the better. The stronger the magnetism, the higher the efficiency of the speaker, and the louder it will be with the same amount of power received.

In general, the larger the magnet, the stronger the magnetism, but each type of magnet is different, so there is a wrong opinion: "The bigger the magnet for the speaker, the better." "Under normal circumstances, the sound quality of a large magnet is better than that of a small magnet, but if the match is not good, the effect is poor, if the magnet is large, the bounce wave should be tight, if the bounce wave is very loose, the power will be distorted.

The small magnet bounce wave must be loose, otherwise the bass will be very dense or even no bass. So the best sound quality should be a big magnet, a tight bounce wave, the voice coil should not be too small, and the stroke should be long enough. I hope mine is helpful to you, I wish you a happy life, if mine is helpful to you I hope you can give a 5 star like.

It's not that the bigger the better, but the stronger the magnetism, the better. The stronger the magnetism, the higher the efficiency of the speaker, and the louder it will be when the same power is received. In general, the larger the magnetite, the stronger the magnetism, but the various magnets are different, so there will be a wrong perception:

The bigger the magnet for the speaker, the better. "Under normal circumstances, the sound quality of large magnets is better than that of small magnets, but if the match is not good, the effect is poor, if the magnet is large, the bouncy wave should be tight, if the bouncy wave is very loose, the power will be distorted. The small magnetic steel bounce wave should be loose, otherwise there will be little or no bass.

So the best sound quality should be a large magnet, tight bounce wave, the voice coil should not be too small, and the stroke should be long enough.

If you are using a traditional cathode tube display, the speaker should not be placed too close to each other. If it is an LCD display, there is no effect.

Sound has the following effects on the cathode tube display:

The magnetic field of the sound causes the computer monitor to be abnormal in color.

Reason: Because the CRT display uses the electron beam to hit the pixels on the glass screen to produce an image, the magnetic flux leakage of the speaker will affect the correct impact position of the electron beam, and then make the display blur. The liquid crystal display uses a semiconductor switch to directly control the pixels, so even if the magnetic flux leakage will affect the semiconductor switch state, it is only a few pixels that have a problem, and the human eye cannot detect it, so it has no effect.

Yes! But nowadays loudspeakers generally have a magnetic shielding device, and the impact is negligible.
