Headphones are an electronic product that I often use in my daily life. How are high-end headphones made? What kind of black technology is hidden in it that can make sales so confident? Maybe you will know after reading its production process.
First, use an injection mill to make the plastic back cover of the earphones. The mesh area on the back cover allows sound to pass through without being reflected back into the earphones. The machine then stamps the logo and product information onto a decorative metal disc and a plastic casing. Then another machine winds the thin oil hair wire hundreds of times around a cylinder. The winding process is controlled by a computer to make the key component of the earphones, the voice coil. When the input signal is magnetized, the voice coil will vibrate. , vibrating it to make a sound. Next, use a press to hot-press the plastic diaphragm to form the prototype of the vibration mold. The press presses the center of the plastic diaphragm to be thicker and the outer ring to be thinner, so as to achieve a wider and more uniform frequency. scope.
Second, immediately use a machine to remove the molded diaphragm, and apply a circle of glue on the surface of the diaphragm. Then place the homogeneous female ring on the assembly equipment, and then apply glue on the diaphragm. The diaphragm is aligned with the negative ring, and ultraviolet light is used to activate the glue and make the negative ring align. The vibration molds are firmly glued together, and there is a magnet on each plastic shell. The next technician installs the diaphragm and voice coil combination on the housing. This step requires experienced technicians because the voice coil must be installed accurately to obtain the best sound quality. Then conduct a sound quality test on the completed speaker to test its audio range, audio dropout, and other phonemes.
Third, next, the technician secures the bent wire end to a plastic clip. These wires serve two functions. They allow the earphones to clip comfortably onto your ears, and they also transmit sound signals from the left side of the earphones to the right side. Then, a connector and a plastic pull-out are immediately installed for the audio cable of the headset, and an adjustable rubber strap is installed, and a hydraulic tool presses the parts together, which allows the headset to fit the heads of different customers. Then use a pneumatic tool to firmly join the two parts of the speaker housing and install a suitable metal ring. Next, the technician placed the speaker core into the center of the casing, then installed protective plastic feet, fixed the entire component to the casing with screws, and then welded the two wires to the speaker of the earphones and used round plastic Cover protects the cord. Let the wire ends be exposed, and finally connect the end of the headband to the speaker and fix it with screws, then weld the wires on the speaker and the wires on the headband together, and finally install a piece of plastic mesh on each of the two speakers, and finally After connecting the wires to the earphones, a headset worth more than 3,000 yuan is completed.
