Extended information:
Computer speakers are divided into connected portable computer speakers, which are single boxes; split computer speakers, which are composed of multiple boxes. Computer speakers, as the name suggests, are used to connect to computers. Of course, many of them can also be used to connect to other playback devices such as mobile phones. Many Bluetooth speakers, card speakers, etc. can be used as connected portable computer speakers after adding external inputs. This type of speakers is very popular in the market.
The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into the space. It is an extremely important part of the sound system, because it is responsible for the key task of converting electrical signals into acoustic signals for human ears to listen directly. It has to directly deal with human hearing, and human hearing is very sensitive. And it has a strong ability to distinguish the timbre of complex sounds.
Since the subjective perception of sound by the human ear is the most important criterion for evaluating the sound quality of a sound system, it can be considered that the performance of the speaker plays a key role in the playback quality of a sound system.
There is a problem of no sound on the computer, such as no sound when turning on the computer, and the small speaker in the taskbar is missing: First of all, the problem of no sound on the computer seems simple, but in fact, sometimes the problem is more complicated, involving both hardware issues and Software issues. It is also common for the sound card to become silent and the small speaker to disappear due to a sudden crash. Therefore, you must first find out the cause to see if it is a software fault or a hardware fault, and then take appropriate measures to address the problem.
1. Check whether the sound card, connecting cables, speakers and other equipment are connected properly. If you are infected by a virus, you should run anti-virus software for comprehensive anti-virus.
2. Open the control panel----Add new hardware----Next step. After the search is completed, click "No, I haven't added this hardware yet" and click Next. In the dialog box that appears, check "Click Finish, shut down your computer and restart to add new hardware." Note that what is said here is shut down and then restart, not restart. Generally speaking, the problem can be solved after restarting the computer.
3. Right-click "My Computer"----"Properties"---"Hardware"----"Device Manager", open "Sound, Video, and Game Controllers" to see if there are any problems. Is there a yellow "?" in front of it? If so, uninstall it first, then put it into the CD drive and reinstall the device driver.
4. If there is no sound card hardware in "Device Manager" - "Sound, Video and Game Controllers", then you have to search for your sound card, including integrated sound cards. The model must be accurate and confirm that the sound card is found. Finally, insert the system drive disk and install the sound card driver.
5. When there is sound but no small speaker, open the Control Panel----Sound and Video Devices----Volume, put a check mark in front of "Put the volume icon into the taskbar", and after restarting, it will appear again in the taskbar. There is a small speaker.
6. When there is no sound or speaker, open the Control Panel----Add and Remove Programs----Add and remove Windows components, put in the CD drive, put a check mark in front of "Accessories and Tools", and click "Next step", the system will prompt you to install new hardware, just follow the prompts to install it.
7. If the problem still cannot be solved, then you have to reinstall the system and driver, and all problems will be solved, but the premise is that all hardware is intact and there is no software conflict.
8. When installing the sound card driver, the prompt "AC chip not found" appears. It may be caused by computer virus, or the sound card plug and play is loose, resulting in poor contact, or the sound card driver may be accidentally deleted due to illegal operations. program, or an internal software conflict. This needs to be solved step by step for different reasons.
9. You can gently tap the casing of the computer body. When closing the lid of the laptop, you can use a little more force than usual to restore some loose parts. Shut down and wait for a while before restarting. Sometimes the sound problem will Get restored.
Method 1:
Check whether the mixing effect of the computer microphone is set to the maximum, and set the effect between 80 and 90; and check whether the microphone is in the enhanced state. The solution is just to remove the microphone enhancement.
Method 2:
Confirm whether there is a problem with the connection between the microphone and the computer host. At this time, disconnect the microphone and the computer host and then reconnect them, and check if there is any poor contact.
Method 3:
Check if there are any working objects with magnetic fields or sound waves around the computer, such as mobile phones, fans, etc. We can just move them away.
Method 4:
We can also check whether there is a problem with the sound card or microphone, such as using a microphone to record audio, or inserting a new headphone device. If an abnormality occurs, it means there is a problem with the sound card or microphone.
1. The card is inserted incorrectly, and the sound card is not tightly separated from the expansion slot of the motherboard. It can be seen through visual inspection that the "golden finger" on the sound card and the reed of the expansion slot are misaligned. This phenomenon occurs on ISA cards or PCI cards. It is a common problem. You can solve the problem by trying to insert the sound card correctly.
2. The input terminal of the active speaker is connected to the Speaker output terminal of the sound card. The active speaker should be connected to the Line-Out terminal of the sound card. The signal it outputs is not amplified by the sound card, and the noise is much smaller. Some sound cards have only one output. Whether it is Line-Out or Speaker depends on the jumper on the card. The default mode is often Speaker, so if necessary, you have to unplug the sound card to adjust the jumper.
3. The version of the installed sound card driver is not good. You may be using the driver that comes with the system. If so, it is best to install a special sound card driver.
Noise from the speaker may be due to damage to the speaker. The damaged part may be the amplifier circuit of the cabinet, or it may be a failure in the speaker part of the speaker. Problems with the quality of music files or abnormal speaker line connections can also cause noise from the speakers.
What are the common causes of noise from computer speakers:
1. Check to see if the wire at the back is loose, pull out the connector and reinsert it, turn on the speaker to listen to the sound, and try where to place the connector. Noise! It may be caused by the wire being kicked or tripped, or the interface being loose.
2. Is there any interference near the speaker? Are there any electrical appliances or mobile phones that are not usually placed? Just take them away
3. Before the noise appeared, did you turn up the sound very loudly and listen to music? If so, it may be a problem with the speakers. Use headphones to listen to see if there is any problem. If not, it is a problem with the sound, otherwise there is a problem with the main sound card of the computer.
7. The computer host’s built-in speakers have noise
Check the cable connection
Adjust Audio Settings
Upgrade the driver
Check for magnetic field interference
Use an isolation device
Conclusion
8. Is there any noise from the left speaker?
1. The audio cable that connects the sound card output end to the speaker, whether the cable itself is of poor quality or the multi-stranded wire or shielded wire of one channel inside is partially broken;
2. The sound card audio The inner yellow edge of the output jack is in poor contact with the 3.5mm plug of the audio cable;
3. Due to long-term use, the volume potentiometer has dust on the internal carbon film, causing noise in one channel;
4. One channel circuit element of the power amplifier The device is defective or the circuit has weak solder joints. You can troubleshoot one by one to determine where the fault is. The noise is really annoying.
Jika potensiometer digunakan untuk jangka masa yang lama, sentuhan yang lemah akan berlaku antara berus logam dan diafragma akibat pengumpulan dan haus habuk, dan bunyi akan terhasil semasa putaran. Jika skru pembesar suara tidak diketatkan dan tiub penyongsang tidak diproses dengan betul, bunyi mekanikal juga akan dihasilkan apabila memainkan muzik dinamik yang besar.
Penyelesaian: Bunyi haba jenis ini boleh ditangani dengan menggantikan komponen hingar rendah atau mengurangkan beban kerja komponen Selain itu, menurunkan suhu operasi juga merupakan salah satu kaedah yang berkesan.
1 Jika bunyi itu disebabkan oleh sumber bunyi, kita boleh terus mencuba sumber bunyi lain dan menggunakan kaedah penyingkiran untuk menghapuskan punca masalah bunyi yang dinyatakan di sini adalah istilah umum , iaitu, alat main balik, lagu, alat muzik, dsb.
2 Jika ia berpunca daripada masalah dengan pembesar suara itu sendiri, maka biasanya kita beranggapan bahawa penceramah penceramah itu hangus. buka dan keluarkan. Terdapat bunyi dari pembesar suara Ini bermakna ia tidak rosak, dan kita masih boleh membaikinya dan lepaskan mengikut amplitudnya beberapa kali sehingga terasa licin Setakat ini, saya menunggu sebentar dan kemudian memasangnya, dan saya rasa saya kembali seperti dahulu. Tetapi jangan bongkar pembesar suara, sapukan sedikit titisan, jika tidak stereo anda akan diburukkan oleh anda.
