Why can t one of my speakers make a sound?

In fact, this problem should be dealt with in two aspects:

First, the problem of active speakers. The check method is to unplug the speaker to connect to the computer,Turn on the volume of the speaker a little more,Turn on the power of the speaker,Touch the top of the plug with your hand (a total of three rings)Two rings,If you can hear the left and right channels respectively"Buzz"Sound,The speaker is good,The problem should be on the computer。 The interference signal detection method is mainly used here, and this method is often used in the maintenance of household appliances.

Second, the problem of the computer, the problem of the computer is divided into software settings and hardware problems. The software checks the settings by turning on the volume control (by double-clicking the speaker icon in the bottom right corner of the computer) and whether the balance button on it is in the middle position, if not dragged to the middle. The problem with the hardware is that the sound card is damaged, and the only way to find a professional to repair it is to find a professional.

However, the probability of hardware damage is quite small.

Through the above inspection, I will definitely be able to solve the problem, I have many years of experience in home appliance maintenance.

It could be a problem with your line, or the song you're playing is mono.

There was a problem with the balance of the volume control, and all that was left upstairs was rookie wow!!

You can adjust it in the taskbar, or you can adjust the balance knob of the speaker.

It may also be a problem with the song, maybe the song is mono, try a different song

Try to adjust the balance of the volume control to the middle!

Agreed"Summer"Of course, it does not rule out the possibility that the amplifier channel is damaged.

Turn on the speakers, play a song, and try to move the connector between the speaker and the sound card.

The problem of the thread is OK when you buy a thread and come back

Four speakers in the car,If there is a sound situation,It may be related to many reasons,Let's find out,How can one of the four speakers in the car have sound?

1. The audio is broken. If only one of the four speakers has sound, the more common reason is that the other three speakers are broken, which can be solved by repair or replacement.

2. The line is aging or the contact is poor. If the line has the problem of aging or poor contact, it is easy to use the audio when there is only one sound, you can check the line.

3. The on-board power supply is insufficient. The audio in the car should have sufficient power when it is used, and if the power of the on-board power supply is insufficient, it is easy to cause only one sound, which can be solved by supplementing the power.

4. Audio setting problems. If the speaker is set to mono, there will be only one sound, so you can change the settings.

There is only one sound of the car audio horn, which may be a problem with the adjustment of the audio channel, or it may be that the power line of the speaker is broken or the horn is broken.

The general car audio can adjust the balance of the left and right volume and the balance of the front and rear volume, and your audio may be tuned to only one speaker.

In this case, first check whether the car machine is improperly adjusted.

1. Swap the two pairs of wires connected to the speaker to see if the speaker still doesn't sound. If the speaker still doesn't sound, the components in that speaker are damaged;

If, after changing the cable, the original speaker that did not sound rings, and the speaker that originally sounded does not sound, it is that the computer audio and the previous part are faulty. If both speakers sound after changing the cable, it means that the original cable is loose.

2. Check the connection cable from the computer to the computer audio, whether a wire is loose, or whether the plug is not in good contact, and plug it back in. Check whether the connection cable from the computer speaker to the speaker is in poor contact or loose. If it still doesn't solve the problem, it means that there is a fault inside the computer speaker, or there is a fault with the computer sound card.

3. If it is a problem with the setting of the sound card, please open the settings interface of your sound card in the control panel (or double-click the small speaker icon of the system tray) to check whether the channel balance is adjusted to the middle, if not, please adjust the balance of the left and right channels to the middle.

4. If the setting is fine, it may be a sound card hardware failure, a sound card output jack failure or a power amplifier, speaker failure, please use headphones to insert the sound card output jack, if the left and right channels of the headphones are ringing, it is your speaker amplifier line problem or a speaker line is broken, if the headphones are also the same channel does not sound, it may be a sound card failure or jack failure.

It may be that your audio amplifier is faulty, first check whether your amplifier has normal power supply, if there is normal power supply, and then check the input and output ports of your audio amplifier to see if there is any poor contact or disconnection. If you don't find any problems, you can try switching to another audio amplifier to see if the sound comes out. If you still have the same problem with another amplifier, it may be that there is a problem with your speakers, and it is recommended that you go to a professional store to check whether your speakers are damaged.

When there is only one speaker in the audio amplifier, first adjust the audio volume to 1 3, and the connection between the speaker, the power amplifier and the signal line is not moving, and they are separated.

NamingThe silent channel isSilent sound, the channel with sound isThere are sound channels。Then check it with the following method:

1. Turn off the power source and power amplifier. The two channel speakers swap positionsand turn it on again.

1) If the silent horn doesn't go off, thatThe fault is in the amplifier and the source and the source line

2) If the silent horn still rings, it means that the original horn that did not sound is brokenReplace the horn

The horns remain in the same interchangeable positionShutdown. Swap two sources of the amplifier port. and turn it on again.

1) If the horn is sounded in a silent channel, it is a silent soundThe source and source line are faulty and need to be repaired.

2) If the horn of the silent channel does not sound, it isAmplifier

Failure of the channel without channels,

Overhaul required

A little more detailed? This phenomenon is related to the sound source, power amplifier, including the wiring horn.
