Process flow of speaker production
First of all, you need to purchase raw materials, 4 major hardware: basin holder (aluminum material, iron material), washer, T iron, magnet, and then 3 major software: voice coil, drum paper, elastic wave, and some small accessories: terminal, Screws, washers, dust nets, dust caps, brocade wire, tin wire, glue (washer glue, magnetic AB glue, elastic wave glue, drum paper edge glue, damping glue, center AB glue, dust cap glue, Washer glue, dust cap reinforcement glue, etc.) Production process: first step: first connect the terminal to the basin frame (note: the terminal is left and right negative, red is black and negative, width is positive and negative) second step: preparation The screw of the glue machine glue wind screw connects the washer and the basin rack. The third step: prepare the T iron, magnet, AB glue machine glue, magnetic gauge and the basin rack that was previously connected to the washer, and apply AB glue to the T iron (the proportion is the same Mix evenly) Put the magnet on the glued T iron and put the magnet positioning gauge to rotate the magnet. Take the magnet and the T iron to connect the edge of the glue for one week. The standard is seamless without breaking the glue. After the AB glue is dried, pull out the positioning Apply AB glue to the magnet and put on the pot holder positioning gauge, then put on the pot holder and rotate for a few weeks until the edge of the washer is connected with the magnet One week of spilling glue is based on the seamless gap without glue breaking, so that the magnetic circuit is completed. Step 3: After the magnetic glue is dried, pull out the positioning gauge, prepare the glue machine, glue, voice coil, elastic wave, drum paper, washer, sound gauge, voice coil positioning table, electronic caliper, etc. First, put the voice coil into the corresponding And use calipers to position "positioning height = (voice coil volume-washer thickness) ÷ 2", then play bouncing voice coil glue, and then connect the positioned voice coil to the bouncing wave and insert it into the T iron center column and turn Move the elastic wave to make it fully adhered (the voice coil must be put in place and not skewed). Then apply the center AB glue to the connection between the elastic wave and the voice coil, and then put the processed drum paper into the voice coil and gently press it. Terminal. Next, apply center AB glue to the connection between the drum paper and the voice coil. Then typeset to dry. Step 3: After the glue is completely dry, unplug the sound gauge, prepare the soldering iron, tweezers, wire cutters, magnetizer, glue machine glue, dust cap, tin wire, sound measuring equipment, and wrap the voice coil leads The wire on the brocade wire should not jump too tight. Clamp the brocade wire on the back of the drum paper with tweezers and insert it into the terminal space. Use the Luotie to weld the voice coil lead to the brocade wire. The solder joints should be full and bright. Welding, use wire cutters to cut off the excess lead wire, then reverse the horn to straighten the wire through the terminal hole, set aside 8-12mm to cut, press the reserved wire into the terminal hole to make the wire There is a certain arc so that the drum paper is not vibrated when it vibrates, and then the soldering joints of the brocade wire and the terminal are the same as above. Prepare the magnetizer to connect the wire and adjust the voltage to magnetize the speaker. The magnetized speaker enters the test room to test and then prepare the glue , Glue machine, dust cap finally typesetting and drying. Now it is basically finished, but speakers with special requirements also need to apply glue to the drum paper, such as: waterproof glue: soft glue on the edge of the drum paper cloth, reinforced glue for the dust cap and so on.
