Problems with computer speakers. Thank you all for Happy New Year. 20

There are several reasons for the "rustling" sound:1. If the potentiometer is worn out and the contact is poor, the potentiometer contacts can be sprayed with WD40.

2。Primary filter capacitance issues, such as failure or leakage. Replace the filter capacitor.

3。The problem of poor contact of the signal line, that is, the line that the computer connects to the power amplifier, can be eliminated by changing a good line.

4。Some elements have leakage. This requires a certain amount of hands-on ability to do it.

Check the interface of the sound card, the audio input interface of the power amplifier, the speaker cable connector, the power cord connector, etc.

Poor line contact or strong electromagnetic interference.

The main problem is the quality of the power supply used in the speaker. You might as well try it:If you have the conditions, find another pair of speakers to replace,If there is an improvement or no such phenomenon,It must be that the power quality of the speaker you are using now is too poor,For some inferior "active" small plastic speakers, this kind of phenomenon will occur.

Solution: If you have the ability to do it, turn on the speaker, first look at the shielding layer of the power transformer is well grounded; Second, if possible, replace the filter capacitor of the power supply to increase its capacitance, and if the withstand voltage value is the same, it is better to double the capacitance. If you don't have the ability to do it, you can only replace some speakers.

But you have to learn a lesson, try it out when you buy it, and make sure there is no communication before you confirm the purchase.

Keep your phone away from the speaker.

If there is a problem with the sound card, if it is an independent sound card, take a look at the contact first, and then don't pull it out and wipe it, and then try to change it from the old machine.

It's better to replace it directly, and if you upgrade, the host will basically have to be replaced, so it's better to change to a new machine.

Green is the usual main sound output, and black is like a bass, which needs to be set to 5 or 7 channels from the audio controller to have an output.

Go buy one of these adapters.

Matching fittings can be purchased, and there are some that are sold.

Of course, most computer accessories stores have cables for sale.

According to the jack of the computer sound output, (generally direct,) choose the audio special connection cable with plug, and the computer jack matching, there are mono and two-channel channels according to the need to choose the connection.

ThinkPad notebooks are relatively stable compared to other well-known brands, and there are no major security problems. At the same time, the overall performance of his computer is relatively good, and it is right that the computer he buys must be the best, and the overall performance is the best. Its sound effect is incomparable to other similar laptops, which can meet your entertainment needs, and its gold medal after-sales service is the best, and a dedicated engineer will write you back to solve the problem.

Lenovo's computer is fine, rest assured! You can play! You don't regret buying the pack.

In fact, it is better to buy an assembled machine, generally with a 22 monitor to buy less than 4000, and the performance is much better than the brand!

If you want to buy a host and a monitor that is integrated, you can buy Lenovo.

If you need to have high requirements for gameplay, it is recommended to buy Samsung or Toshiba.

I suspect that there is radio or electromagnetic interference near your computer. For example, high-power power generation equipment, substations, and so on.

I encountered this situation when I was doing a performance, because the wireless microphone was interfered with by electromagnetic waves, and it also emitted a "whoosh" sound from the speaker, and it was also sent out with frequency.

It is recommended that you change the position of your computer and try it somewhere else.

It's not a hardware problem, that's the software.,And it's not a software problem to play anything.,It's a software problem that the system must use.,It's recommended to reinstall the sound drive.,If it's not not good, it's recommended to reinstall the system.,Anyway, there's a ghost system now.,When you install it for ten minutes or so,It's not okay to swish.,It's really not cool.,Finally, I hope it can help.。

Is the button plugged in correctly? It's the same with our party, but it's just a matter of buttons, and you don't know

Could it be a problem with the audio?

Definitely not split lines.

If your sound card supports it, one port is connected to the front and bass, and the other port is connected when the rear is connected, and becomes a new set if you want to use only the bass+ speakers.

It seems that this is not possible.

Unless you change the circuit inside the speaker.
