Sooner or later, every homemade music lover is faced with the repair or alteration of the sound source of his speaker system. The reason may lie in mechanical damage to the diffuser, corrugation or center suspension, and in electrical damage to the voice coil, which happens more often. And in order to fix this, you need to rewind the coil to change its resistance, then the acoustics will not conflict with the amplifier.
Instructions
Step 1
Disassemble the speaker. To do this, take it out of the speaker box and place it on a flat, clean surface. Make sure that there is not only household dust nearby, but also small metal objects, sawdust or crumbs.
Step 2
Unsolder the flexible conductors from the shoe that lead to the voice coil. Keep in mind that the conductors used for this purpose consist of thin copper strands twisted with natural or synthetic filaments to provide maximum flexibility and elasticity. To maintain the quality of current leads, exclude accidental impregnation of the veins with rosin during soldering.
Step 3
Remove the dust cap. To do this, gently moisten it with solvent to soften the glue. It is impossible to say which solvent is suitable for the job, because there are so many types of adhesives used in speaker assembly. Therefore, you will have to select a solvent in the process. Use a small disposable syringe to apply the solvent directly to the adhesive site. Also moisten the center suspension skirt and peel it off.
Step 4
Rewind the spool. If you know the parameters of the speaker coil (wire diameter, number of layers, number of turns in each layer), simply remove the remnants of the old winding. If this information is not known, carefully rewind each layer of the winding and count the turns. Then select a piece of coiled wire, where the insulation is not damaged, measure the diameter of the wire with a micrometer and select the wire with the closest diameter possible.
Step 5
Assemble the speaker in the reverse order, thoroughly gluing everything. Replace the diffuser first, then the central hanger skirt and lastly the dust cap. After assembly, test the speaker first at low, then at maximum power. If there is no extraneous noise during testing, feel free to mount the speaker to the speaker system.
