How to check the speaker?
How often does your technique fail you? Surely, in your life at least once there was a situation when the equipment failed right before your eyes. Why does this happen? Perhaps, acquiring something new in your home, you didn’t carefully examine the product and purchased it with minor defects. In this article we will tell you about the performance of speakers and speakers, we point out what you need to first pay attention to, acquiring such a technique.
So let's start with the speakers. Suppose you decide to buy equipment and want to check the work of its built-in speakers, but do not know how to do it? How to check the speaker? First of all, pay attention to the sound box, which is located directly in the middle of the speaker. It is a wire that is wound in the form of a ringlet. Remember, everything that is in a music box should not have any defects. The cord should not be broken. If they are, then the speaker will no longer work.
If you do not have the opportunity to look at what is in the middle, then the speakers can be checked with the help of special devices, for example, with a multimeter, ohmmeter or with a resistance measuring device. As you can see, if you yourself can not determine the condition of the speakers you purchase and the speakers built into them, the above devices can help you.
Another very simple way to check the quality of the speakers right in the store is to ask the seller to connect them to a computer and turn on some video or music.
