The mobile phone is next to the stereo, and the stereo rings for no reason

There are many situations that will cause noise in the computer audio, such as the speaker is interfered with, the interface or connection line is not in good contact, and the sound itself is of poor quality.

Generally speaking, computer audio is mostly active speakers, and there will be amplifiers inside, so noise is inevitable, and the noise of active speakers can be roughly divided into electromagnetic interference, mechanical noise and thermal noise.

Electromagnetic interference can be mainly divided into power transformer interference and stray electromagnetic wave interference. Generally speaking, the power transformer interference is caused by the power flux leakage of the multi-speaker speaker, and the effect of installing a shielding cover for the transformer is very obvious when conditions permit, which can block the magnetic leakage to the greatest extent, and the shielding cover can only be made of iron materials. We should try to choose products with big brands and solid materials, and in addition, using external transformers is also a good solution.

Stray electromagnetic interference is common, and speaker wires, crossovers, wireless devices, or computer hosts can all become sources of interference. Keep the main speaker as far away from the computer as possible and reduce the number of peripheral wireless devices.

Mechanical noise is specific to active loudspeakers. During the operation of the power transformer, the core vibration caused by the alternating magnetic field will produce a mechanical noise, which is very similar to the humming sound emitted by the ballast of a fluorescent lamp. Choosing the best product is still the best way to prevent this noise.

In addition, we can add a rubber shock absorber between the transformer and the fixing plate.

It should also be noted that if the potentiometer is used for a long time, the contact between the metal brush and the diaphragm will be poor due to dust accumulation and abrasion, and noise will be generated when it rotates. If the screws of the speaker are not tightened, and the inverter is not handled properly, mechanical noise will also be generated when the **big dynamic**.

This thermal noise can be dealt with by replacing low-noise components or reducing the working load of the components, and reducing the operating temperature is also one of the most effective methods.

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

The situation you are talking about is caused by cell phone interference.

Because the mobile phone automatically searches for the base station by default, it will send a signal to go out to explore the base station from time to time to determine the location. Even if you don't call, don't send text messages, or surf the Internet, your mobile phone will emit electromagnetism.

When your mobile phone is used very close to the audio, fixed**, TV, etc., it will be interfered by the strong signal of the mobile phone.

Of course, if you don't use it and place it very close to the speaker, the speaker will squeak from time to time, because the mobile phone will automatically get in touch with the station at any time, and the mobile phone and the station will exchange signals with each other.

If the phone rings, your computer screen will vibrate", it should be "tumbling or shaking".

To put it bluntly, it is the interference caused by the radio waves emitted by the mobile phone too strong.

Mobile phone Internet, calls, text messages will produce a large number of electromagnetic waves, the sound speaker is composed of a cone, coil and magnet, the shell of the audio has not been shielded, in the case of electromagnetic signal interference, the sound coil is interfered with, and then a pulse sound signal will be generated. This rental pulse signal is amplified by the sound circuit and sent to the speaker, at which point a screeching sound is heard.

Solution: 1. Choose better audio equipment and signal lines, because the design of the audio circuit is more reasonable, and the effect is better in anti-interference.

2. Keep the mobile phone away from the audio, so that the interference of the audio is small or none.

The phone is connected to the speaker + why the speaker still has no sound.

Hello, your phone has been successfully connected to the speaker, but there is no sound from the speaker, it may be caused by the following reasons: the volume is not set correctly. Check that the volume settings of your phone and speakers are correct.

Sometimes, the volume settings of your phone and speaker may affect each other, resulting in no sound. You can try turning up the volume to make sure they are set to the right volume. The audio input is set incorrectly.

Check that your speaker has selected the correct source input. Some speakers may have multiple source input options, such as AUX, Bluetooth, optical, and so on. Make sure you select the correct source input.

The Bluetooth connection is unstable. Sometimes, the Bluetooth connection may be unstable, resulting in no sound from the speaker. You can try reconnecting Bluetooth, or closing the distance between your phone and speaker to make sure the signal connection between them is stable.

Acoustic malfunction. If none of the above methods solve the problem, then there may be a malfunction in the speaker itself. You can try to check if the power of the speaker is turned on, and whether the other settings of the speaker are correct.

If there is still no sound, then the speaker may need to be repaired or replaced. It is important to note that different brands and models of speakers may have different issues, so the workarounds may also be different. If you can't solve the problem, it is recommended to consult the audio manual or consult the relevant technical support for meditation.

Summary. The mobile phone is connected to the speaker + why the speaker still has no sound Hello dear,1To check the power connection, you need to check whether the power of the Bluetooth speaker is turned on, whether the power is sufficient, or whether the power connection is intact.

2.Turn off Bluetooth If there is no problem with the power supply, then we will turn off the Bluetooth of the mobile phone, turn off the Bluetooth speaker, and then reconnect it. 3.

Check the volume of the phoneIf there is still no sound after reconnecting, then we need to check the volume of the phone and turn up the volume of the phone. 4.Check the volume of the speakerIf there is still no sound after adjusting the volume of the mobile phone**, then check whether there is a volume adjustment button on the Bluetooth speaker, and you also need to turn the volume up.

Summary. 1.There is no sound from the Bluetooth speaker, adjust the volume of the mobile phone as needed, and keep the mobile phone and the Bluetooth speaker within 10 meters.

Hello <> kiss

I turned on the stereo, Bluetooth was already connected, but I didn't sing.

What's going on.

Kiss, you turn up the loudest voice.

The solution to no sound after the phone is connected to the speaker is as follows:

1.There is no sound from the Bluetooth speaker, adjust the volume of the mobile phone as needed, and keep the mobile phone and the Bluetooth speaker within 10 meters.

2.If the Bluetooth speaker battery is too low or there is no power, charge the Bluetooth speaker in time for a period of time and turn it back on.

3.The volume of the mobile phone is adjusted to the lowest, so there is no sound, you can adjust the volume of sound roll in the sound option in the mobile phone settings, or you can use the volume keys of the mobile phone to adjust. Grinding round.

Your connecting tube is probably a mobile phone charger, right?

Because the power supply current of the power supply such as a mobile phone charger is too small to drive this speaker, it is necessary to find a matching 5V DC power supply.

In the past, most of the old electrical appliances were black, as long as the output voltage was 5 volts, and the interface could be matched. You can also find a 9-12 volt one, and you can also install a 5-volt three-terminal regulator, but you need to install a radiator when the regulator block.

The sound of the mobile phone connection speaker is intermittent1, and the Bluetooth version is not compatible enough. 2. The speaker is too far away from the mobile phone. 3. It is caused by the unstable connection of the blue jujube tooth.

4、It is very likely that there is a problem with your **** software,It is recommended to shut down and try again,No,Uninstall and re-press the **device,This should not be a hardware problem,It is a problem with the software in this regard5、It may be that the signal is not strong,Although the leakage is marked as a few meters away from the product can be linked,But this is the distance that excludes the obstacles,There are obstacles between the mobile phone and the Bluetooth speaker will reduce the strength of the Bluetooth signal。

1. There is no sound when the speaker is plugged into the mobile phone because the ear of the mobile phone is equipped with the lead machine jack and the speaker plug does not match.

2. The headphone jack of the mobile phone is matched with the four-segment three-pole headset plug, and there are more microphone contacts for the first pole. The audio plug is a three-segment two-pole (left and right channels + common poles), and the contact head cannot match it.

3. You need to buy a headset plug, replace the plug of the audio cable, and when welding, leave the pole that communicates with the headphones vacant, or connect a resistor to the public ground. Refers to or if you don't know how to get it, in the electrical accessories store, let the merchant help weld it.
