First of all, you need to purchase raw materials, four major hardware: basin frame (aluminum material, iron material), washers, T iron, magnet, and then three major software: voice coil, drum paper, elastic wave, and There are some small accessories: terminals, screws, washers, dust screens, dust caps, brocade wires, tin wires, glue (waste glue, magnetic circuit AB glue, elastic wave glue, drum paper edge glue, damping glue, center AB Glue, dust cap glue, gasket glue, dust cap reinforcing glue, etc.) Production process: Step 1: Connect the terminals to the basin frame first (note: the terminals are positive on the left and negative on the right, red is positive and black is negative, wide is positive and narrow Negative) Step 2: Prepare melter glue, air screws, and screws to connect the washers and the basin frame. Step 3: Prepare T iron, magnets, AB melter glue, magnetic gauges, and the basin frame to which the washers were connected before. Apply AB glue to the T-iron (the ratio is the same and mix evenly). Place the magnet on the glued T-iron and insert the magnet positioning gauge. Rotate the magnet. The edge of the magnet and T-iron is connected with glue overflow for a week to ensure that there is no glue break or gap. Wait for After the AB glue is dry, remove the positioning gauge, apply AB glue to the magnet and put on the basin frame positioning gauge. Then put the basin frame and rotate it for a few weeks until the edge of the connection between the washer and the magnet overflows with glue for one week. The standard is that there is no glue breakage and no gap, so that the magnetic circuit is complete alright. Step 3: Wait for the magnetic circuit glue to dry and remove the positioning gauge. Prepare the glue machine, glue, voice coil, elastic wave, drum paper, gasket, tone gauge, voice coil positioning table, electronic caliper, etc. First, insert the voice coil into the corresponding position. Use a caliper to locate the "positioning height = (voice coil width - washer thickness) ÷ 2", then play the voice coil rubber, then connect the positioned voice coil to the elastic wave, insert it into the T iron center column and turn Move the elastic wave to fully bond it (the voice coil must be placed in place and not skewed), then apply center AB glue to the connection between the elastic wave and the voice coil, then insert the processed drum paper into the voice coil and press lightly, and the brocade wire must be aligned terminal. Then apply center AB glue to the connection between the drum paper and the voice coil. (Note on center glue: Mix the AB glue evenly and do not add too much glue. Overflow and leakage of glue will cause rub circles.) Use a jig to gently press the edge of the drum paper to cause the glue to overflow. The layout is then left to dry. Step 3: After the glue is completely dry, unplug the tone gauge, prepare a soldering iron, tweezers, wire cutters, magnetizer, melter glue, dust cap, tin wire, sound measuring equipment, and wrap the voice coil lead around On the brocade wire, the lead cannot be too tight. Use tweezers to pick up the brocade wire on the back of the drum paper and thread it into the terminal hole. Use Luo Tie to weld the voice coil lead to the brocade wire. The solder joints must be full and bright, and there must be no false welding or leakage. Solder, use wire cutters to cut off the excess lead wire, then turn the speaker upside down to straighten the wire that passes through the terminal hole, leaving 8-12mm for cutting, and press the reserved wire back into the terminal hole to make the wire There is a certain arc so that the drum paper will not hit when vibrating. Then weld the brocade wire and the terminal to the same requirements as above. Prepare the magnetizer and connect the wires. Adjust the voltage to magnetize the speaker. Put the magnetized speaker into the test room for testing and prepare glue. , glue machine, dust cap and finally typesetting and drying. Now it is basically a finished product, but speakers with special requirements still need to apply a layer of glue on the drum paper, such as: waterproof glue, soft glue on the edge of the drum paper, reinforcing glue on the dust cap, etc.
