No matter on the road, on the bus, or on the subway, people with earphones are everywhere. Wearing earphones can fully integrate into your own world. It is really very pleasant. However, among the many people who wear headphones, how many people have the habit of cleaning headphones? How many people know that the bacteria will multiply several times after wearing the headset for one hour? Headphone manufacturers remind everyone that wearing headphones often affects health. Many people have raised doubts about this. In fact, after wearing the headset for an hour, the bacteria can multiply by up to 5 times. If you don’t wash it all year round, it will accelerate the bacteria’s multiplication. The impact on human health depends on one’s own resistance.
Although everyone feels that if the headset is not cleaned for a long time, it will not have much effect on the body, but this varies from person to person. When the body’s resistance is good, they will not make people sick. If an individual’s resistance drops, they will make people sick. Therefore, for your own health, you still have to clean and disinfect earphones and other personal items on a regular basis; moreover, your own earphones are for your own use, not for others to use, so as not to generate more bacteria. Headphone manufacturers remind citizens to use better quality wet wipes for disinfection, or use a cotton swab dipped in alcohol to wipe. The specific operation should be based on the quality of the headset to choose the disinfection method.
The key production processes of headset manufacturers include: 1) mold opening, 2) injection, 3) cable assembly, 4) sound head (or speaker drive unit) manufacturing, 5) PCB assembly, 6) painting and screen printing, 7) Final assembly, 8) quality control test, 9) packaging.
At present, many headset manufacturers believe that SMT is a non-core manufacturing process, which is more cost-effective through outsourcing, and is especially conducive to small-scale production. In addition, electronic component manufacturing and mold manufacturing are two other production processes that are outsourced by more and more companies. Therefore, the production focus of general headset manufacturers is basically focused on the cables and speakers that determine the quality of the headset. Therefore, most of them also have their own cable and speaker exciter assembly workshops. In addition, many companies may also import earphone cables and high-quality speakers according to the buyer’s requirements. In addition, manufacturers need to be equipped with internal quality control equipment to perform QC and QA testing, according to the national GB2828 and AQL standards to implement the quality control process from IQC, IPQC, OQC to FQC.
In order to ensure quality, headset manufacturers often need to have a wireless module R&D test shielded room, and at least equipped with two channels of automatic distortion measuring instrument, stereo signal generator, oscilloscope and simulator. Other R&D tests include wire swing test, abrasion test, vibration test, tensile test, high and low temperature/humidity test, and at least 5,000 to 10,000 insertion tests. The test equipment needs to be equipped with a spectrum analyzer, a signal generator, a dual-frequency RF power meter, a high-frequency RF amplifier, a network generator, a Bluetooth tester, an audio generator, an oscilloscope, and a withstand voltage meter.
