Imagine, you might be giving some speech, and your speakers fail. It feels like the most embarrassing situation to handle. Regardless of whatever device you are using, it is important to have a great multimedia sound experience. A machine made by man has some time limit to work properly. And so, speakers are also manmade devices that sometimes become defective.
Whether the speaker is new, old, expensive, or inexpensive, you will get some problems related to sounds. Identifying and fixing those problems will help you to some extent. Most of the people face some common problems of the speakers like noise distortion, damaged speaker cone, broken phasing, no sound issue etc. and many more.
If you hire someone else to fix these types of speaker problems then you need to spend a lot of money and it would become an expensive process. To save some amount of your money, we have bought a solution for all common problems that may arise in your speakers.
So, here comes a list of those problems that you may face in your speakers and a solution for those problems. Let’s get started:
Voice coil damage and overheating
Most of the common problems in speaker failure are overheating of the voice coil. The loudspeakers have a combination of electronics that are powerful enough to guarantee distortion-free noise. But when voice coil gets overheated then the amplifier sends the signal that is not clean. But what causes burnt voice coil? When the voice coil got fired then it can lead to an electrical surge.
Here are the most common reasons that will lead to burning voice coil in speakers. They are:
- One of the common reasons the voice coil gets burnt is because of the power amplifier.
- It is known that when the electrician fits the most powerful amplifier in the speaker that is higher than its bearable capacity then it may lead to distortion of voice.
- With too high watt amplifier in the speakers, it may lose control of the sound level and may lead to the destruction of bass speakers.
- Amplifier’s malfunction may also lead to a burnt coil.
- Using too high power or too low power amplifiers in the speakers may make the sound wires too weak.
- This will lead to treble in speakers.
- With the less power amplifier, the speaker may not able to produce a high-level sound that may lead to the burning of the voice coil.
- If direct current will pass through speakers then this would lead problems in it.
- Sometimes it may also happen that there could be a problem in setting up the connection between the wire and speaker terminals.
- So, it causes rapid intervention of the sounds that will surely damage the voice coils of speakers.
- Besides technical errors or setup errors in the speakers, using speakers with its excessive volume may lead to damage to coils.
- It is the fact that the increased volume will make the situation worse and destroy the amplifiers associated with speakers.
So, these are some common problems that will cause voice coil damage and overheating. And if your speakers have these problems then we have a perfect solution for you.
We will recommend you to use a high power amplifier that will provide a good amount of comfort and will not exceed 100 Watts per channel. This would surely help you in removing voice distortion.
Failure in Flexible wire of Speakers
Wires are the most important components of speakers that will make the connection between speakers and audio amplifiers. The speakers coming nowadays have wires consisted of electric conductors coated in plastic. It is the well-known fact that most of the wires in speakers have conductors and insulators that do not add any effect in the sound.
When the wire in the speakers gets damaged then this will affect the sound quality of the speakers. If the correct size wire used in the speaker then there would be less chance for breakage of speakers. If the long length of wire used in the speaker then it will create inductance causing the reduction of sound frequencies.
To protect your feed and flexible wire from breakage, you should keep wires in between crosses fairly short. Short wires will increase the tenderness in the sound while the long wires are responsible to change their behaviour in response to the sound of the speaker.
Many claims are made due to the problems caused by fancy wires used in the speakers. These fancy cables will not only destroy speakers but also lower its quality.
If your wire has some inductance and capacitance then it will not hurt your sound but only filter out the certain sound ranges. So, instead of long wires, use short wires that will protect your wire from breakage.
Coil breakage or glue removed from wires
This type of situation mainly occurs when the speaker cone gets detached from the coil. It happens when you make the use of speakers for a longer time.
The heat in the speakers make the coil to detach from the wires make it sound distorted. The large speakers can be repaired more easily while the short or inexpensive speakers take time to repair.
Another main reason for the detachment of glue from the coil is due to moisture and dampness. These factors will grate the sound coming from the speakers. Only those speakers in which rubbing can be heard have chances to repair easily. This mainly comes in short speakers.
To repair the speakers the coil has to be placed in the spider and re-glue the coil to gain its sufficient mobility. In some cases, it is possible to resemble the coil.
To replace the coil, the magnet needs to be removed and glue should be applied to the areas of the new coil and fit them accordingly. Once it has been done, proper care must be taken to ensure no further damage will occur in the coil.
Failure of Cone Structure in Speakers
Cone in the speakers is surrounded by polyester foam. If any of the parts in this cone structure gets broken then it makes lead to failure of the cone. Cone is the part of the speaker that is responsible to provide output from the drivers.
If you experience no sound coming from the drivers then it is possible that some part of the cone structure gets broken. You can identify the speaker problem by the following:
- Check the fuse if the sound is not coming from the drivers.
- There are many sound drivers. Test all of them. If none of them is giving output sound then there would be a problem in the receiver.
- Also, test the speaker by slightly pressing the cone with your index finger. If you experience the hardness in the voice coil then check the drivers, as no movement in the cone has resulted with the fault in drivers.
- If you experience the fussy sound then there is a chance that the speaker cable may be damaged.
To solve these types of issues in the cone structure of the speaker, you need to follow these steps:
- Disassemble all the parts of the speaker. Do this after unplugging the speaker unless you will get an electric shock.
- The front part of the speaker is mainly used for drivers problem.
- Check the drivers and after that lift, those drivers placed in the front of speakers and get access to wire connectors. Use some sharp tools like pliers to remove the cross over the network of wires.
- Find the unit that gets fused and you can take the help of multimeters to repair them.
- Once you repair them, put all the parts together and test the speaker again.
- In most of the cases, the problems get solved. If the problem still persists then you need to meet an expert electrician.
If you have a speaker that creates no sound then it is of no use. Right? No, you are wrong. Speakers have the efficiency to work properly only if they are repaired. Repairing process of speakers becomes expensive if you hire someone to do it. In this article, we have discussed some useful tips that will surely help you to solve some common speaker problems very easily.
