Headset manufacturers to remind you often wear ear opportunities affect health
Whether on the road, on the bus, or on the subway with headphones everywhere, bring headphones can be fully integrated into their own world, really is very comfortable. However, many people wearing headphones in the crowd how many people have the habit of cleaning headphones? How many people know that in fact, after wearing an hour headphones, bacteria will multiply several times? Headset manufacturers to remind you often wear ear opportunities affect the health of many people raised doubt. In fact, wearing an hour headphones, bacteria up to breeding nearly 5 times, if the perennial does not wash will accelerate the bacteria breeding. The impact on people's health depends on their own resistance.
Although we always feel that a long time did not wash the headset on the body did not much impact, but this is different. When the body resistance is good, they will not make people sick, if an individual resistance decreased, they will make people sick. Therefore, for their own health, or to regular headphones and other personal items for cleaning and disinfection; and, their own headphones is to use their own, not to use others, so as not to generate more bacteria. Headset manufacturers to remind the public can be better quality wipes disinfection, can also be dipped in alcohol dipped cotton swab, the specific operation according to the quality of headphones to choose disinfection methods.
(1) open mold, 2) injection molding, 3) cable assembly, 4) sound head (or speaker drive unit) manufacturing, 5) PCB assembly, 6) painting and screen printing, 7) Assembly, 8) quality control test, 9) packaging.
At present, many headset manufacturers that SMT is a non-core manufacturing process, through outsourcing more cost-effective, especially for small-scale production. In addition, the manufacture of electronic components and mold manufacturing is the other two more and more companies outsource the production process. Therefore, the general focus on the production of headphones manufacturers are basically focused on the quality of the cable and the speaker on the decision. As a result, they also have their own cable and speaker exciter assembly shop. And, many companies may also be in accordance with the requirements of the buyer to import headset wire and high-quality speakers. In addition, manufacturers need to have internal quality control equipment to implement QC and QA testing, according to national GB2828 and AQL standards to implement from IQC, IPQC, OQC to FQC quality control process.
For quality assurance, headset manufacturers often need to have a wireless module R & D test shielding 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, wear test, vibration test, tensile test, high and low temperature / humidity test, and at least five thousand to 10,000 times the insertion test. The test equipment should be equipped with spectrum analyzer, signal generator, dual frequency RF power meter, high frequency RF amplifier, network generator, Bluetooth detector, audio generator, oscilloscope and pressure meter.
