Why is my bass sizzling when the speaker is not pressing?

This should be considered normal, I didn't learn physics very well in middle school, and the specific explanation is not clear, but I think about it may be like this:

When your hand touches the strings, because the strings are metal, they are conductors, and your body becomes a conductor at this time, connecting the electricity to the ground, and putting the excess electric current on the ground. Maybe at this time, your body becomes like a "ground wire" on the electrical plug.

And when your hand is not touching the strings, the excess current in it will run around, interfere with each other, and then be picked up.

Pick it up, and it becomes noise.

The above is the principle I speculated on myself, I don't know if it's correct, I didn't study physics well when I was in school, and I forgive me for explaining it incorrectly.

It's not uncommon for this to make noise without touching the strings, so if you watch a rock band perform live, the musicians will either clench the strings with their hands or turn off the volume on the piano when they don't need to play to avoid the noise. Bass generally doesn't need a distortion effect, and if the guitar is connected to the distortion effect, the noise will be very loud and unpleasant.

In addition, if your piano has been making noise, whether you touch the strings or not, it means that there is a problem with the circuit inside the piano, please take it to repair the guitar bass.

Let's repair it.

Generally, if the shielding is not done, it can be solved by finding an electrician, or taking it to the piano shop. There is also a situation where the quality of the speaker and the connecting cable is too poor, and there will be noise.

Summary. Plucking the strings with two fingers to increase efficiency can make a difference. Rotate the strumming between the thumb and middle finger.

It doesn't matter which string you start with, as long as you keep the speed and rhythm going. Playing a smooth and warm tone near the neck of the piano. If you play too close to the bottom of the instrument, the strings will make a more impactful sound.

When practicing, play in a small area without moving up and down too much. Pluck the strings with your fingertips. Don't pull the strings so it doesn't make a good sound.

If you want to increase the volume, turn on your speakers instead of plucking the strings too hard.

Plucking the strings with two fingers to increase efficiency can make a difference. Round between the thumb and middle finger and change the potato. It doesn't matter which string you start with, as long as you keep the speed and rhythm going.

Playing a smooth and warm tone near the neck of the piano. If you play too close to the bottom of the instrument, the strings will make a more impactful sound. When practicing, play in a small area of the chamber without moving up and down too much.

Pluck the strings with your fingertips. Don't pull the strings so it doesn't make a good sound. If Zhao Min wants to increase the volume, turn on your speakers instead of plucking the strings too hard.

Is the left hand pressing the string so that the other strings don't vibrate?

Yes, don't push the strings too hard, but you can press your fingers on the strings to prevent resonance and make a sound!

Can a string only produce one note?

It is very appropriate to have two notes per string instead of one note. It's a bit wasteful to play just one note.

So how does it play two notes?

When ascending, the first note is pronounced by playing the string with the right hand, and the second note is pronounced by the left hand Wang Rent to quickly strike the string and style the world. On the downward movement, play the first note with your right hand, and then use your left hand to hook the string in the direction of the vertical string to make the second note.

First of all, determine whether there is a problem with the grounding wire (connecting wire) speaker The connection line inspection method is: twist the connector of the connecting wire to see if there is any looseness, if it is loose and tight, then connect the speaker, if there is still noise, play the piano while twisting the connector on the connecting line, listen to whether the sound will get better, if the sound will get better and sometimes worse when twisting the connecting wire, then this is the problem of the connecting wire.

The speaker check method is to first turn off all the reverb and bass adjustment buttons on the speaker, only open the volume button, use a new connection cable or you think it must be a good connection cable to connect the speaker, and then turn off your piano's so timbre adjustment button, if you are an active pickup, then first change a new battery, and then turn off the active pickup switch, only turn on the volume button of the piano, pluck the strings to try, if there is a sound, then it is easy to do, one by one switches and knobs are switched and tried, Find out if the reason is on the button or on the battery, if there is still no way to make a normal sound, then it is a problem with the speaker or the piano, this kind of thing is not something you can repair yourself, you need professionals, you can only take it to the piano shop to repair, take the speaker and the piano to see, just as a routine inspection, don't be afraid of trouble, check clearly only the benefits and no harm.

In this case, you should first check whether there is a problem at the wire interface, the socket of the line is very fragile, especially the place at the end of the terminal port, long-term twisting is easy to contact poorly, and then check the speaker, the speaker check is actually very convenient, since the line is no problem, then start to constantly adjust the timbre, to see if the speaker can still be used normally, and finally the piano, if your piano is an active pickup, then you need a battery to pronounce, the battery is leaking or almost out of power, the sound may be intermittent, It is not excluded that there is a problem with the internal wiring of the piano, anyway, as long as it is not a problem with the piano, then there is nothing to do, and it will not be very complicated to get started.

It should be a connection problem! ~

If it doesn't work, try a different speaker! ~

It's hard to say what bass yours is active or passive Have you checked the cables?

There are several possibilities:

1. Your bass has a signal like this to the speaker, check the bass equipment.

2. The connection between the bass and the speaker is poor, and there is a false connection, resulting in noise.

3. Noise reduction of audio. You can try to see if other devices have this sound when they input to rule out speaker problems.

If it's a current noise, it's a grounding problem.

You look at your bass adjustment, and it's probably current, so it's recommended to change the piano or search the internet for filtering or something.

The plug-in and unplugged cable must be turned off, otherwise the coil in the instantaneous current change box will produce a strong self-inductive voltage, which is easy to burn out the audio! !

Regarding what you said that there is noise, it is normal, or that sentence, the wire is connected and then turn on the power! You don't connect the guitar with the wire, there is electromagnetic interference in our air, the mobile phone, the induction cooker or something is very strong, and the input of your speaker is very sensitive, so you just buy a 100,000 yuan speaker like you don't connect the guitar suspension line will also have noise!!

As for the shift gear, there will be a momentary current change inside the circuit, so it is normal to have a small noise, I haven't seen it yet, and theoretically it is impossible to have no at all.

Also, if your line and speaker guitar are connected, if there is continuous noise, it is the problem of your line, the line is very important, otherwise the price difference of a line of the same length will not be so big, it is recommended that if you buy a similar guitar, it is equipped with a good line, and it is comfortable to listen to.

If there is still this phenomenon after the sound is controlled,It should be that your audio sound is turned on too much, right? voice The small point should be fine, and the new speaker should not have the problem of breaking

This is the potentiometer of the amplifier is broken. Generally, there are 2 methods, 1. Find the amplifier manufacturer and ask them to help repair it (brand machines generally have a formal warranty), and the warranty period can also be guaranteed. 2. Change the power amplifier.

When choosing a speaker, you can compare with each other to avoid such a situation, for example, Huiwei and Dynaudio can talk about these two first, many friends have told me, Huiwei is more difficult to push when it is actually used, the investment in power amplifier is large, and it is not good to listen to; The design and manufacture of Dynaudio large voice coils are more difficult and costly, so it is still very expensive, If you are not an audiophile, it is not recommended to choose, to tell you about the BT-audio ab HIFI set, the AB bookshelf box is a HIFI box with excellent comprehensive performance, reproducing the classic pure British sound. Using super instantaneous reaction unit, the treble is not scattered, the bass is not sticky, the strong sound is not dry, the weak sound is not false, the warm and mellow sound shows the infinite charm of the **, you can feel the legendary and charming melody of the British sound, and enjoy the bloodline, sound quality, and workmanship are all excellent HIFI speakers. The style contained in the AB bookshelf box comes from the unique design of BT-Audio's sound engineers, with a refined and elegant appearance, to create a bedroom and study desktop HIFI speaker.

There will be some problems with the speaker after a long time, such as the speaker volume adjustment knob does not work. How can this problem be solved? Let's find out.

1. No matter whether the knob is turned to minimum or maximum or any middle section, the speaker sound is the maximum volume when normal.

2. When the knob is turned to the minimum or maximum, the sound is slightly smaller; When the knob is turned to any of the middle sections, the sound is slightly louder and slightly muddy.

3. The fault of the knob potentiometer has been eliminated, and the resistance value of the potentiometer is measured with a multimeter, and it is found that it can change uniformly with the rotation of the knob.

Maintenance method: Normally, the potentiometer is rotated to the minimum is to short-circuit the input signal directly to the ground, and become no signal transmitted to the power amplifier, and the power amplifier is absolutely silent. According to the above, the potentiometer can not be adjusted after changing it, that is, the signal is not short-circuited to the ground, and the potentiometer is good, then the only explanation is that the copper foil of the grounding terminal of the potentiometer of the power amplifier plate is broken (or the link wire is broken), which causes the signal to be unable to short-circuit the ground wire (or there is a large resistance).

It must be a bad contact, a bad plug contact, a bad volume potentiometer, a bad contact with the terminal, etc.

If the knob doesn't work, just change it! The sound is adjusted by the potentiometer, and when the knob is not in good contact, it will cause a sound and no sound failure. The potentiometer is a mechanical electric shock, and the voltage divider adjustment method directly causes the potentiometer to heat up, so the fault of the potentiometer is very high.

In this case, you can directly solder it down and change it to a potentiometer of the same model and nominal resistance. If you really can't do it, you can go to the repair shop and ask them to help you replace it, but the repair shop charges relatively high. As long as you can accept it!

The situation you mentioned is that the contact points of the audio knob are somewhat worn, and there will be a problem of intermittent sound, and it is very simple to solve it, remove the knob, buy a bottle of resurrection spray and spray it evenly, and turn it a few more times to dry it, if you can't buy resurrection spray, you can also replace it with alcohol.

The wiring is falsely connected, the volume adjustment knob potentiometer is faulty, and the plug is not plugged in properly or dirty, resulting in the conductive path being turned on and off.

This can only be ruled out,Make sure the speaker is fine,The system is fine,Then the sound card and driver are left。 Replace the lower driver and try again.

It should be that there is a problem with the line, find a professional to repair it.

It should be that the thread inside is loose, just open it and solder it again.

There should be a problem with the line, so let's find a professional to repair it.

The sub speaker speaker is in poor contact. 2.Check the cable of the sub speaker.

Lock screen, with the popularity of smart phones, many users use lock screen software to protect their mobile phone privacy. But the mobile phone lock screen is similar to the computer lock screen, and there are two kinds, one is to cut off the power of the screen, and the other is to use software to quickly and intelligently.

I can't play with the mobile phone card.

You can take a picture and search on **or look at the brand and model of the headphones, enter the keyword search on Jingdong**, it is estimated that you can find me, I often look for things like this, maybe I am a fortune teller, so I can guess what the headphones of your problem look like, so check the problem, but you can take**go** to find the same headphones with Polar Tao.

That's right, there's something wrong with that switch resistor, just change it. :

The switch is broken, and so is mine.
