What should I do if the electric piano has a noise, but the electronic piano makes a noise?

1. The friction noise between the copper pedal and the left and right borders of the pedal hole on the piano body: it is generated when the pedal is stepped down and lifted, and it is easy to judge by visual inspection, which is caused by the deviation of the pedal flap from the middle of the pedal hole. Processing:

For minor cases, wax can be applied to the bezel of the tread hole, and in severe cases, the screw position of the metal shaft bracket that holds the copper tread flap in the body should be adjusted.

2. The noise of the copper pedal and the upper frame of the pedal hole on the body: when the pedal flap is raised, it can be judged by visual inspection that it is caused by the feeling falling off or stiffening of the upper frame of the pedal hole. Treatment: Repair or replace with new felt.

3. Friction noise between the lever beams of the pedal valve: generated when the pedal flap is stepped on and lifted, it can be judged by visual inspection, and the action is judged: the noise disappears when the two adjacent pedal lever beams are pulled apart by hand at a certain distance and when the pedal is stepped on and the pedal is lifted.

Treatment: Apply wax or pad soft cloth and tweed at the friction point, if not, adjust the position of the pedal lever beam fulcrum axle screw.

If there is noise in individual keys during playing, it may be caused by the resonance between the horn and a certain part of the body, which can be found and eliminated by hearing.

If there is noise after booting, it means that there is a quality problem with the power circuit of the panel. It is recommended to go to a repair point for repair.

An electric piano is an electroacoustic instrument. It is a musical instrument that emerged in the sixties and seventies of the twentieth century and was popular in the eighties and early nineties to replace the piano on certain occasions. The sound principle is to use the keyboard as a switch, once the key is pressed, the internal crystal oscillator begins to work, generating a waveform of a certain frequency, and then amplified by the frequency divider, sent to the speaker to emit sound.

The whole sound process relies on a simple crossover analog circuit, so the keyboard has no dynamics and a sense of stringing, and the sound is relatively mechanical and monotonous.

Use a one-click restore to see first, not to find after-sales service.

Either it's a problem with the wiring, or it's a problem with the keys and the sound source, and if the noise is obvious, send it for repair.

If the electronic organ makes a noise, you have to listen carefully to what the sound is, if it is because it comes from the horn, then there may be a problem with the horn, just change the horn, if it is because there is a problem with the sound of the electronic keyboard, then you have to repair the parts of the electronic keyboard.

Some. You can try to put the headphones on other computers less, if the noise is still very loud, there may be the following reasons:

1. The sensitivity of the earphones is too high, and a small audio voltage can push it.

2. If the shielded wire of the earphone falls off, or there is no shielded wire at all, the shielded wire should completely wrap the signal wire in the form of a braided belt, instead of replacing it with an ordinary single-core ground wire;

Solution: 1. Change the headphones with lower sensitivity and higher impedance;

2. Replace the signal cable of the earphone with a mesh braided signal cable with a shielded wire;

3. Find a friend who understands electronics and welding between the signal line and the ground wire of the left and right channels, and put on a ceramic capacitor 683 or 104.

When the monitoring headphones are connected to the sound card or computer, I put on the headphones but I hear the sound of electric current, microcurrent, and noise of computer miscellaneous. There are many cases of noise in the headphones, and if the computer is muted, the headphones will be noisy. Apply for a training course to find Suntech institutions, you can provide free consultation, zero yuan audition, tuition discounts, is a must to improve academic qualifications, Suntech is a vocational education institution, established in March 2003.

The electronic organ is the backbone of an electroacoustic band and is often used to play a solo main theme accompanied by rich harmonies. It also often appears as a solo instrument, with distinctive characteristics of the times. But the limitations of the electronic organ are also obvious:

The melody and harmony lack volume changes, and are too harmonious and singular; When imitating various wind and string instruments, the technique is slightly monotonous.

Noise from electronic organ monitoring headphones? It doesn't have to be the noise of the headphones, it should be the "inductive" current sound of the power adapter.

If this is the case, then you can go to the after-sales service of the electronic organ, and give you a cigarette to see if there will be no noise?

Why 670 Electronic Keyboard? You can't listen with headphones. This was the design at the time, and there was no such function. So you can't listen.

There is noise in the electronic organ monitoring headphones, it may be a problem with its own quality, and it is damaged during use, so if you don't debug it well at this time, it is recommended to go to a professional store to take a look and ask for help from professional maintenance staff, I think they should be able to solve this problem.

Summary. Hello kiss after the inquiry is because:

This is mostly caused by the small filter capacitance of the audio power amplifier power supply of the electric piano.

What is the reason why electric piano has electric current sound and how to solve it?

The reason for the inquiry is that most of this is caused by the small filter capacitance of the audio amplifier power supply of the electric piano.

Solution: Open the chassis, find the power amplifier power supply, replace the two electrolytic capacitors less than 2200 microfars with more than 4700 microfarads, and connect a hollow small inductor in series with the two capacitors if you have the ability to repair, the effect is moreIf it is an external power supply, it is recommended to deal with or replace the external power supply with better performance according to the above methods. If the above treatment can not be solved by the local chain, this may be a defect in the circuit design of the whole machine, and the analog signal can be drawn from the electric piano to the special power amplifier, which should be completely solved.

Summary. Hello dear! It can be solved, but it needs to be sent back to the manufacturer for repair or find an electronic organ repair shop for repair. In fact, at present, electronic organs will face loud noise, out of tune, and key failure, and electronic organs cannot be adjusted and changed, and need to be repaired.

Electric piano, the key rebound noise is high, can it be solved?

Hello dear! It can be solved, but it needs to be sent back to the manufacturer for repair or to find an electronic organ repair shop for repair.

In fact, I have played the electronic organ for a few years, and I have bought a lot of electronic organs, and I will also encounter the situation of loud noise and affect the sound effect, I myself also sent it back to the manufacturer for repair, and the later cover to make the rubber manufacturer also sent it back to the object, and it is also the manufacturer's side to solve the problem of loud noise, so you don't need to worry about it, you can send it back to the manufacturer or find a piano repair shop for repair.

Summary. If the electric piano is energized but there is no sound, first of all, you should check whether there is any problem with the wire, and check whether the output port of the piano is correct after confirming that the wire is not faulty (including faults such as poor contact). In addition, you can also check whether the input port of the speaker is correct and whether there is any problem with poor contact.

Of course, it is also important to check whether the electric piano is the specified output and whether the settings are correct. If it still can't be solved, it is recommended to seek professional help to solve it.
