With the improvement of people's living standards, more and more friends began to choose good headphones to improve their quality of life. Headphones on the market range from a few to hundreds of thousands. Usually, everyone will adopt the mentality of “a penny and a share†to think that the higher the holiday, the better the earphones. In fact, this judgment is not professional. And a good headset is where it is, how a headset is designed and manufactured, there must be many friends have great questions, today Xiaobian for everyone to analyze as an excellent headset, what should be?
Basic flow chart for headset development For a headset, the design is the first element. On the one hand, the appearance of a headset determines the first impression of the consumer. On the other hand, the appearance of a headset will have a relatively large sound. Impact. Generally, this part is designed by industrial designers with high artistic aesthetic level. At the same time, acoustic and structural engineers will participate in the design process to avoid the situation that particularly affects the acoustic structure or even the mold.
When the design is completed, the industrial designer transfers the 3D file without internal structure to the acoustic engineer/structural engineer for the acoustic structure design. This part mainly involves the following aspects: 1. Installation of the sounding unit, 2: size of the acoustic cavity before and after, structure, shape and size of the venting hole, position design, 3: design of the sounding mode.
The above three aspects are the most important components. For a dynamic ring earphone, the moving coil unit separates the front and rear acoustic cavity of the earphone, and the front and rear cavity have different effects on the sound of the sound, which can be adjusted through the back. The sound net cloth adjusts the sound. Of course, there are some special acoustic structures that have some special effects on the sound. It takes a lot of time to do well in this part, and a good acoustic structure has a great influence on the sound. Good headphones and poor headphones are in this part. Will open the gap. The acoustic structure of the moving iron earphone is relatively simple, the sound tube design of the front cavity is more important, and the rear cavity is relatively less demanding.
Moving iron headphones are relatively simple. There are not many companies that can manufacture moving iron units in the world. Generally speaking, the choice of existing moving iron units is enough. Of course, if you have enough qualifications or enough orders, you can also let the moving iron manufacturers help you develop custom-made customizations, and then sign the exclusive agreement, so that others will not be so easy to imitate your headphones, can only say close, Can't be exactly the same. Whether you can customize your own moving iron unit is also a manifestation of the strength of the headset manufacturers. There are two kinds of irons. It is a common practice to develop dynamic coil units to match existing moving iron units.
The tuning of the dynamic headphones is usually in the front and rear tuning holes. The sound holes are controlled by the tuning mesh or the tuning paper, and the sound absorbing sponge is used to control different sounds. Of course, a good earphone will combine sounds in the tuning part. The unit part, even the acoustic structure is adjusted together, is an iterative process, and sometimes it takes a little luck. After all, there are too many influencing factors. The tuning papers of different manufacturers have the same sound. The big difference, sometimes just happens to be very nice, sometimes because of a little glue, the sound is not right, it is very interesting.
Better headphones will also filter out some good silicone sleeves at this stage. Different silicone sleeves have a greater impact on sound. Choosing a silicone sleeve that is comfortable to wear and sounds well is also an important part of tuning. The coarse adjustment in this part is usually by looking at the curve, and the fine adjustment must be based on the auditory comparison of the human ear. The combination of the two can achieve better results.
The sound debugging part determines the direction and completion of the final sound. This part is usually communicated by the brand side and the foundry side. A good earphone is constantly being ground. Of course, the tuning of this step is only a rough adjustment, because the wire is usually not done well, the material of the hand, the smoothness of the surface and the final product still have a large gap, and there will be a process of secondary tuning. This is teamwork. Of course, if one can do it, it is okay for this person to call it a tuner, but in more cases it is done by a series of people including acoustic product manager + acoustic engineer + art consultant.
The above is a basic process of designing and manufacturing a headset. An excellent headset must be excellent in every aspect from design development to production. Any problem in one link will affect the quality of the product. An excellent earphone is not only excellent in sound, but also good in product quality, durability, wearing comfort, consistency, etc., and it is worthy of the title of “good earphoneâ€. I would like to use this article to inspire others. I hope that more friends will be more rational and objective when discussing headphones, instead of discussing "Xuanxue" blindly. I hope everyone has a rational fever and use music to add more colors to our lives.
