This picture lacks the central positioning piece (elastic wave), dust cover and lead (pigtail). If you understand it, I will not draw it. Someone asks me to continue looking.
1: Folding ring, together with the elastic wave, position the drum paper (diaphragm, paper cone) for radial movement. The material of the folding ring generally has rubber, cloth base and adhesive paper, etc. The softness and softness of the folding ring directly affects the linearity of the drum paper in the whole motion formation, and affects the performance curve of the speaker in the entire nominal power.
2: Drum paper is the main sounding part of the speaker. The material is mainly pulp and other materials. In recent years, various materials with different characteristics have entered, including polypropylene, carbon fiber, titanium metal, etc., and even diamond. However, the mainstream is still pulp, on the one hand, the cost is low, on the other hand, it is easy to make the complex curved surface required by the horn diaphragm.
3: T iron, splint. The material is soft iron, that is, pure iron, also called electric iron. The main characteristic is magnetic conduction, but there is no residual magnetism. After the magnetic field disappears, its magnetic properties disappear immediately. The purity and quality of this iron directly affects the efficiency of the horn, nonlinear distortion and other important parameters, wherein the thickness of the splint affects the stroke of the horn. The T-iron splint of the long-stroke speaker is extremely thick, so that parallel parallel magnetic lines of force can be cut throughout the entire travel of the voice coil. The smaller the gap between the splint and the T-pillar, the smaller the power required for the movement of the voice coil is, the higher the efficiency of the speaker. Therefore, the magneto-type speaker injects magnetic fluid between the T-iron and the splint, which is equivalent to reducing them. The distance between the two sides also quickly removes the heat of the voice coil, improving the power capacity of the speaker.
4: Magnetic steel, generally called magnet, permanent magnet, magnetic steel is called more accurate. Before the speaker is assembled, there is no magnetism. After the T-iron splint is glued with the adhesive, it is magnetized on the magnetizer. The final remanence is the magnetic properties of the magnetic steel. This residual magnetism is the magnetic size of the magnetic steel. According to Faraday's law of electromagnetic induction, the larger the magnetic flux, the greater the force of a certain current moving in the magnetic field. Therefore, in order to increase the power of the speaker, many ferromagnetic materials such as neodymium iron boron are now applied.
5: voice coil: generally flat self-adhesive copper enameled wire wound, is a very contradictory component, in order to increase the current (increased power), the wire diameter will increase, the wire diameter is large, the magnetic gap is required to be large The magnetic gap is large, and the power efficiency is decreased, so the intermediate value can only be taken in the contradiction. The voice coil is generally wound in two layers, and the single layer winding cannot lead the wire. In order not to change the size of the magnetic gap and increase the magnetic field formed by the current, the diameter of the voice coil can only be increased. So with the HiFi speaker claiming a large voice coil, long strokes. The voice coil is wound on a paper skeleton, and the high-powered speaker frame is made of aluminum foil, the so-called aluminum voice coil. The voice coil is still copper, and the skeleton is aluminum!
6: Shield: magnetic leakage prevention components, generally soft iron, but some low-cost speakers in order to reduce costs with carbon steel, ordinary iron plate production, anti-leakage effect is greatly reduced, in fact, this form of leakage prevention has been The effect is not good, there is still a small amount of magnetic leakage, in the strict requirements of the leakage-proof magnetic field, the speaker magnet is installed in the position of the middle pole of the T-iron, so that the entire magnetic line system is closed, there is no static leakage. Of course, this requires that the magnetic flux of the magnet is very large, the processing requirements are also high, and of course the cost is also high.
7: Lead wire (formerly we called pigtail), it is composed of copper wire and cotton thread, which is mainly to keep the voice coil and external wire connected normally under the vibration environment of the speaker.
Some of the above are read by the book, some are information found on the Internet, only have reference value, the wrong place welcomes the pat, and the missed welcome. I hope someone can talk about the structural principles of electrostatic speakers.
In the magnetic shielding, there is also a mirror magnet that has forgotten to talk about it, that is, using the magnetic fields in the positive and negative directions to cancel each other to reduce the leakage flux!
Here again a few words:
Speaker (the mainland name) = speaker (Hong Kong and Taiwan called the law)
Speaker (the mainland name) = speaker (another name in the mainland) = speaker unit (Hong Kong and Taiwan called the law)
Since I am on the mainland, I always follow the custom of the mainland.

Center positioning film:
This is one of the most important parts of the horn. When the previous industry was not so developed, the competition could not find the artificial thing to be able to handle this small piece. Only one kind of plant - Ge Ma was prepared and then pressed to obtain the speaker. The physicochemical properties required by the central positioning film, so in the 1960s and 1970s, the West had restricted the export of such plant products to China. It is not that China does not have such hemp, but the production process is not good. It is good to respond to Chairman Mao’s call. The workers' brothers overcome this difficulty. Today's speakers are mostly made of chemical polymer fabrics. The characteristics are very close to Ge Ma, but the high-end Hi-Fi speakers are still made of Ge Ma. In addition to the high material requirements, the height of the corrugation, the physical value of the shape density curve affects the sound quality, and it is not easy to make it. Interested friends can find further information and bonding center positioning piece. The glue is also very particular about the bonding between fabric and metal. Today, the development of polymer chemical adhesives is no longer a problem. The key is that the current speaker manufacturers do not pay attention to this glue. I have seen a lot of speakers with this problem. There is also a bonding process, and the bonding process causes the dispersion of the speaker quality.
Basin frame:
The speaker frame mainly supports the stable connection of the drum paper and other components of the speaker. Its rigidity has great influence on the sound quality. The general speaker will be stamped with galvanized steel plate to form a corner rib or embossing rib at the edge. Why press the ribs because thinner materials can be used for cost reasons. This is certainly not the first choice for high quality speakers. High-powered loudspeakers are now generally used in cast aluminum basins, which are lightweight, rigid and easy to machine into the desired shape. Since the speakers are generally installed vertically, due to the influence of the gravitational force of the earth, especially the speakers of large magnetic steel, the weight of the rear part is very large, so the side of the basin frame will be particularly strengthened to offset the deformation caused by the installation method. The best speakers are installed up and down, and will not be able to fit 360 degrees because it is round. Domestic HiFi manufacturers pay little attention to this problem, and foreign best speakers regard this as a trade secret - this is why the same domestic manufacturer with the Shishi Shidi poetry speaker can't make the same good sound speaker (of course, the factor is not only this point). However, I have seen the support of the board behind the speaker in the speaker made by the enthusiast. I have tried it, but I have not heard the change of the sound quality. Maybe the influence of other factors is even greater. There are still engineering plastics for the basin, but the rigidity is still not good. I don't think it will become mainstream in a short time.
In addition to the supporting role, the mid-range speaker frame is a small speaker, which is closed. The good quality speaker will also put sound-absorbing cotton in this small speaker to improve the sound quality.
Dust cover:
The materials are varied and the shapes are varied. Why is this because, in addition to the dust-proof effect, the beauty of the horn depends on it. Among them, the large dust cover represented by Danish Daniel has become a part of the sound of the diaphragm. There is also the soft dust cover of domestic Huiwei, which solves the problem that people can't press it. As for the improvement of sound quality, I can't agree. Among them, the Huiwei 10" carbon-plastic polypropylene speaker gives up the soft dust cover because the dust cover will suck down at high power, and it is only used in the 8" caliber. It is also the earliest yarn dust cover, the most scientific, the air resistance is very small and can be dustproof, not as part of the sound, it will not affect the paper cone frequency response curve that has been designed according to the surface equation. Then there is the bullet, the foreign brand is represented by the West Asians, and suddenly heated up in the country around 97 years ago. As for the improvement of the sound quality, the benevolent sees the benevolence, the wise sees the wisdom. One thing is certain, this smooth surface will definitely form an acoustic focus somewhere in the space, and the sound focus is always a good replay system to avoid, just like the photographic technique to avoid stray light points.
This picture lacks the central positioning piece (elastic wave), dust cover and lead (pigtail). If you understand it, I will not draw it. Someone asks me to continue looking.
