It s the bass horn, how do you remove it to see the copper wire?

Take out the voice coil to see the copper wire (enameled wire of the voice coil) It is very difficult to operate, you must be careful: 1 Use banana water to carefully apply around the dust cover, slowly remove the dust cover after the glue softens, and store it carefully. 2. Use four paper strips of suitable thickness to insert the gap between the voice coil skeleton and the middle core column to avoid scratching the voice coil winding when the voice coil is taken out later.

3 Solder open voice coil leads. 4 Use banana water to soften the glue that binds the paper cone between the sides of the paper cone (or plastic cone or film cone, depending on which material your horn is) and the edge of the horn holder, and carefully peel it off until it is completely disengaged. Note that this can't be saved, if you want to pull the voice coil out of the middle of the cone hole, because the diameter of the winding of the voice coil is larger than the cone hole, it can't be extracted.

5 Extract the connecting body of the voice coil and the paper cone from the core column. In this way, you can see the enameled wire of the voice coil (the copper wire that the landlord said). If you want to separate the paper cone from the voice coil skeleton, you can also use banana water to soften the viscose.

You'd better measure whether the horn's coil is open or the resistance is zero! If it is disconnected and there is a need to disassemble and repair, the resistance value is zeroed (the coil breakdown of the horn) is not necessary to repair it, and the horn is replaced directly! The paper cone of the horn should be separated from the magnet to see the coil of the horn, and the horn coil is glued to the horn paper cone.

It is very simple to see the copper wire of the horn, and the place where the paper cone is torn off and the iron core is the copper wire coil. If the horn coil is broken, it generally cannot be repaired. The coils of the tweeter are interchangeable.

The subwoofer is generally inside the speaker, and the cover must be removed from the back to see it.

What you want to see is the coil of the horn, the copper wire or... If you look at the coil, it is difficult to repair without professional technology.

The woofer burns out and the terminals need to be replaced.

The speaker bass is broken,Disassemble the stereo to see if there is a bulging capacitor,If there is, remove it and replace it,There is also to see if the electronic component screwed on the heat sink is burned black,Remove the black and replace it。 A speaker is a device that converts an audio signal into sound. Generally speaking, it means that the speaker host cabinet or subwoofer cabinet has its own power amplifier, and the audio signal is amplified and the sound is played back by the speaker itself, making it louder.

Reason: The woofer is an important speaker unit in the speaker, and its low frequency makes the sound from the speaker feel strong and surging, and the ears can resonate and shock.

Although the chance of a woofer burning out is much lower than that of a tweeter, it can still easily cause the woofer to burn out if used incorrectly.

The more common reason is that the model input to the power amplifier is too large, many friends feel that the speaker sound is too small, and they can't wait to turn on the volume fader or gain knob of the mixer to the maximum, and the power amplifier indicator directly bursts the red light, and then the woofer burns out.
