3. Adakah bunyi dari pembesar suara dan komputer?

Banyak situasi boleh menyebabkan bunyi pada pembesar suara komputer, seperti gangguan daripada pembesar suara, sambungan yang lemah dalam antara muka atau kabel, kualiti pembesar suara itu sendiri yang tidak baik, dsb.

Secara umumnya, pembesar suara komputer kebanyakannya adalah pembesar suara aktif, dan mesti ada penguat di dalamnya, jadi bunyi bising dari pembesar suara aktif boleh dibahagikan secara kasar kepada gangguan elektromagnet, bunyi mekanikal dan bunyi haba mengikut sumber.

Gangguan elektromagnet boleh dibahagikan terutamanya kepada gangguan pengubah kuasa dan gangguan gelombang elektromagnet sesat. Secara amnya, gangguan pengubah kuasa disebabkan oleh kebocoran magnet bekalan kuasa pembesar suara multimedia Apabila keadaan membenarkan, kesan memasang penutup pelindung pada pengubah adalah sangat jelas, yang boleh menyekat kebocoran magnet ke dalam. takat yang paling besar. Penutup pelindung hanya boleh dibuat daripada bahan jenis. Kita harus mencuba yang terbaik untuk memilih produk daripada jenama besar dan bahan pepejal Selain itu, menggunakan pengubah luaran juga merupakan penyelesaian yang baik.

Gangguan gelombang elektromagnet palsu adalah agak biasa, dan wayar pembesar suara, silang, peranti wayarles atau hos komputer semuanya boleh menjadi sumber gangguan. Letakkan pembesar suara utama sejauh mungkin dari hos komputer dan kurangkan peranti wayarles persisian.

Bunyi mekanikal adalah unik kepada pembesar suara aktif. Semasa operasi pengubah kuasa, getaran teras besi yang disebabkan oleh medan magnet berselang-seli akan menghasilkan bunyi mekanikal, yang hampir sama dengan bunyi berdengung yang dikeluarkan oleh balast lampu pendarfluor. Memilih produk yang berkualiti masih merupakan cara terbaik untuk mengelakkan bunyi bising ini. Di samping itu, kita boleh menambah lapisan menyerap kejutan getah antara pengubah dan plat tetap.

Another thing that should be noted is that if the potentiometer is used for a long time, poor contact will occur between the metal brush and the diaphragm due to dust accumulation and wear, and noise will be generated during rotation. If the screws of the speaker are not tightened and the inverter tube is not properly processed, mechanical noise will also be produced when playing large dynamic music.

This kind of thermal noise can be dealt with by replacing low-noise components or reducing the component workload. In addition, lowering the operating temperature is also one of the effective methods.

In addition, some computer speakers will produce noise when the volume is turned up too loud. This situation is caused by the fact that the output power of the power amplifier may be small and cannot avoid the large dynamic peak signal at the moment of music, or it is caused by the speaker overload distortion.

4. Does the computer audio make noise when it is not plugged into the computer?

1.

Electromagnetic wave problem Computer speakers have noise, which is often caused by interference from stray electromagnetic waves. Common sources of interference include: speaker wires, crossovers, wireless devices, etc. Solution: At this time, we must place related equipment correctly. For example, the main speaker should be as far away from the computer host as possible.

2.

Microphone problem If there is noise in your speakers, there may be a problem with the microphone settings. For example, the mixing effect of the microphone is not maximized, or the microphone is set to be strengthened

3.

Sound card If there is noise in the problem speaker, it may also be caused by the influence of surrounding magnetic field/sound wave objects. However, if there is a problem with the sound card,

5. Is there any noise in the computer audio amplifier?

1. It is caused by the problem of the sound source.

　2. Because the speaker is burned out, there will be noise when playing the speaker.

　3. Due to the contact problem of the input and output lines, there is obvious noise in the speakers.

　4. Problems with the audio hardware caused noise in the audio.

　What to do if there is noise in the speakers

　1. If the noise is caused by the sound source, we can directly try another sound source and use the elimination method to eliminate the cause of the noise problem. The sound source mentioned here is a general term, that is, Players, songs, musical instruments, etc.

　2. If the speaker is burned out, we can listen carefully to which speaker it is, and after confirmation, open it and take it out. If there is sound from the speaker, it means it is not broken, so we can also repair it. The easiest way is to use a household speaker Drip vegetable oil into the copper ring of the speaker, and then slowly press and release it according to its amplitude a few times until it feels smooth. Then wait for a while and install it, and it will return to the previous feeling. But don't dismantle the speakers, just apply a little drip or you will make your speakers worse.

　3. If the problem is caused by the line, then we first consider changing the line, but we don’t know yet whether it is the line problem, so we can try to repair it. Check the circuit to see if there is any breakage. If so, just reconnect it and re-wrap it with tape. If not, all we have to do is check the connector. It is easy to have problems with the connector. If it is a plastic rubber head, then we have to change the wire. Even the connection is not ideal. If it is metal, we can repair it ourselves, and then test the effect one by one after the repair is completed.

　 4. If there is a problem with the audio hardware, go directly to someone to repair it, or buy a new one.

　 Solutions to noise in the audio

　 1. Check whether the mixing effect of the microphone is maximized.

Solutions to noise in the speakers: With the microphone, increase the mixing volume to 80 to 90%

6. Is there any noise in the speakers due to a leakage in the computer motherboard?

If there is noise in the computer, you can solve it as follows: 1. Make sure the audio plug is correctly inserted into the back panel of the case (generally, the pink round port on the back panel of the computer case is the microphone and microphone jack; the green round port is the audio, speaker and other amplification The blue round port is the

line input

(such as MP3) socket) and there is sound (no matter what the sound is, as long as there is sound).2 Click the "Start" button (you can also press the Windows logo key on the keyboard) to pop up the

Start Menu

. Mouse click on

Control Panel

. See the

Control Panel

page. 3. Click "Hardware and Sound" (green text) in the pop-up "

Control Panel

" page. to bring up the hardware and sound control page. 4. Click "Realtek High Definition Audio Manager" (item 6, green) in the pop-up hardware and sound control page. to pop up the Realtek High Definition Audio Manager page. 5. There is a blue "Device Advanced Settings" button in the upper right corner of the Realtek High Definition Audio Manager page. Clicking it will pop up the advanced settings page. 6. In the advanced settings page, select the radio button in front of "Separate all input jacks into separate input devices". Then press "OK" in reverse order of the pop-up of all windows. Note: There are usually two reasons that affect the sound effect: 1. Line problems. If the contact is not reliable, the mainboard leakage will cause other voltages and currents to be mixed into the circuit. The most original and effective solution is to add a capacitor to absorb interference, but it requires professionals to do it; 2. It is the interference of electric fields and magnetic fields. Such as microphones, mobile phones, electric fields of internal combustion engines, magnets,

communication base stations

, the magnetic field generated by the satellite. The most primitive and most effective way is to cover the perimeter of the speaker with a completely airtight wire mesh, allowing the self-circulating wire mesh to form an

electrostatic shielding

cover for the speaker. This can block out all

electromagnetic interference

except the speaker itself.

9. Why is there noise when the speakers are connected to the computer?

This is because there is a problem with your host or monitor. The static electricity or leakage generated by them when they are turned on and run causes the sound paper of the speaker to vibrate, resulting in noise. You can try using another brand of speaker to estimate the problem. The solution is similar to resonance. When you change a speaker with another vibration frequency, the resonance frequency will change, so resonance will not occur. If the problem still persists after changing the speakers, try changing to a socket with a grounded wire so that the static electricity or leakage generated by the computer can be discharged. The effect will be better.

10. Will the computer crash as long as the speakers make noise?

1. If the screen is stuck, accompanied by a "sizzling" sound coming from the speaker, it is likely that the rectifier and filter parts of the host power supply are faulty;

2. It is difficult to wake up the computer after hanging up (entering sleep), indicating that the host The power dissipation of the power supply is low; if the first fault of the host power supply exists, a low power dissipation fault will occur;

3. Sometimes the screen is blurred when playing games, which can indicate the +12V voltage of the host power supply On the low side; based on the above, it is recommended that the author focus on checking the host power supply.
