Why is the speaker easily burned.Changde Bar Speaker wholesale

　　The speakers in the audio system are often burned or broken. Most people intuitively think that it is too loud that the horn cannot bear it, so it breaks the speaker. In fact, there are many cases that may be caused by the burning of the horn.

　　1. It is too loud to open the horn, that is, the normal use power of the horn. Another situation is that the power of the machine is insufficient and loud, and the output is abnormal cutting signals. This situation will also damage the speaker.

　　2. If there is a DC output, it will definitely burn the bass speaker, and even a few tweeters will be burned. The reason is that there is no capacitor isolate DC on the bass (or other sound path) speakers. The output of DC is like the DC power is into the speaker, and the scorer coil is burnt. Therefore, when buying an enlarged machine, pay attention to whether there is a DC output at the output end of the front and rear levels with a meter. If there is a DC output in the front stage, it may also amplify the output through the rear level to spread the DC into the speaker.

　　3. Wit wipe diligently, and the line head is locked; the so -called connecting is the connector of the signal input and output. These joints are inevitable to be eroded by air after a long time of use. When the surface produces a layer of oxides, the joints and mother insertions have a layer of oxides, is it still useful for the signal line you to buy a lot of money? What does it mean to lock on the line? The wire head refers to the horn head head. If the horn head is not locking, the impedance changes generated may have adverse effects on the low frequency, and it will easily burn the speaker. According to the Jazzing Dragon manufacturer's summary experience, it is best not to use the end of the bass speaker wire, and lock the nude line directly on the connection end, which will get the best contact surface. If you must use the terminal and try to use a thin and soft pure copper Y -type insert, this terminal can be locked tightly. The thicker the more terminal contact, the worse the effect. If the output input terminal can be clean and the speaker cable is tight, it is as if the blood path of the human body is not hindered, the sound will definitely be better, and the speaker is not easy to burn.
