Plain paper cone speakers structure

This figure was the Centre in the Tablet (elastic waves), dust cover and lead (tail), you know I'm not painted, someone asked me to continue to look for. 1: folding ring, and play the waves with positioning drum paper (Cone, cone) radial movement. Pack ring material General rubber, cloth and adhesive tapes etc, rings and soft and pliable, directly affect the drum paper formation throughout the movement, the impact of linear speakers throughout the nominal power of performance curve. Paper 2: the drum is the main part of the sound the Horn. Materials are primarily pulp and other material, in recent years, a variety of different materials into, polypropylene, carbon fiber, titanium, etc, and even diamond. But the mainstream or pulp, on the one hand, low cost, easy to make the speaker diaphragm requires complex surfaces. 3: T iron, splint. Made of soft iron, pure iron, also known as electric iron, the main character is the permeability, but there is no residual magnetism is the magnetic field disappears, it will immediately disappear of magnetic. This iron purity and quality, the efficiency of the direct impact of the Horn, nonlinear distortion, and other important parameters which influence of thickness of splint Horn stroke. Long-stroke speakers T iron splint is particularly thick, just the whole trip in voice coil can cut parallel to the uniform of the magnetosphere. Splints and T iron column gaps, voice coil motor power is needed, the smaller the higher efficiency of the speakers, speaker at magnetofluid seal type T between iron and splint, equals magnetic fluid injection reduces the distance between them on the one hand, and the voice coil heat quickly away, increasing the capacity of the speaker's power. 4: Alnico magnet, General call, permanent magnet, magnetic translation more accurate. In the speaker Assembly is not magnetic before, at and t iron splint after adhesive bonding, IPL, finally on magnetizing is Alnico remanence magnetism, the amount of residual magnetism is Alnico magnetic size, according to Faraday, flux, certain current in magnetic fields, the greater the force of the movement, so in order to improve the speaker power, now applies a number of strong magnetic materials such as iron, boron, RB. 5: voice coil: typically flat self adhesive copper wire wound, is a very contradictory parts, in order to increase the current (increase power), the diameter is increased, wire diameter, called the magnetic gap is larger, the magnetic gap, power efficiency decrease, so you can only remove the conflicting intermediate values. For a two-layer voice coil General wound, single-layer winding cannot pin. In order not to alter the magnetic gap size and increase the current form of the magnetic field, you can only increase the diameter of the coil. So there is a large HiFi speakers claimed, long stroke voice coil. Voice coil is wrapped in a paper on the skeleton, high-power speaker skeleton is made of aluminum foil, aluminum voice coil. Voice coil or copper, skeleton is aluminum. 6: shielding enclosures: MFL components, typically soft iron, but there are some low end speakers in order to reduce the cost of carbon steel, iron-making, non leakage magnetic effect is greatly reduced, in fact, this form of magnetic flux leakage-proof has not been, or have a small amount of leakage flux, magnetic flux leakage-proof the strict requirements of occasions, speaker magnet is mounted on the uprights T iron location so the entire magnetic closure system, no static magnetic flux leakage. Of course this requires magnets magnetic flux is very large, processing requirements are high, and, of course, cost is high. 7: leader (previously we called pig-tailed), is a compilation of copper wire and cotton thread, mainly in the speaker vibration environments voice coil and the external conductor connection properly. Some of the above is a book to know that some are online to find information, only the reference value, the wrong welcomes film brick, missed welcome to add. Hope someone to talk about structural principle of electrostatic speakers. Place in magnetic shielding and a mirror to Alnico forgot about, is the use of positive and negative direction of magnetic flux leakage counteract weakened! here then nonsense words: speaker (Mainland crooner) = Horn (RTHK crooner) speaker (Mainland crooner) = Horn (Mainland another call) = driver (RTHK crooner) because I was on the Mainland, so articles will follow the continental habits are known. Continue to the left: the Centre in the film: this is the Horn is one of the most important part, previous industry not so developed, the King could not find anything man-made qualified for this small branch, only one kind of plant-based GE Ma, and then pressing process-to get speakers Centre in the movie the required physical and chemical properties, in the 1960s, the West on the plant products should limit exports to China, not the Chinese do not have this species in the genus, but do not cross the manufacturing process, in response to Chairman Mao, our workers brothers overcome this difficulty. Now many of the speakers are made of chemical polymer fabric, this branch has been very close on the property of GE Ma but upscale Hi-Fi speakers still adopt GE Ma. Positioning plate in addition to the materials require high or low, corrugated, shape, density curve various physical values are affecting sound quality, and not just production can, interested friends can find further information and bonding Center positioning of gum is also very high, is the fabric and metal bonding between polymer chemistry today adhesive development today, no problem, the key is now the speaker manufacturer and do not attach importance to the gum, casually was, I saw many of the speakers. There are bonding process, bonding process caused the dispersion of quality speakers, here is not to say the basin rack: speakers basin rack main support drum paper and speakers of other parts of stable connection, the influencing of rigid great sound quality, General speaker will use galvanized steel sheet stamping, forming the edge bends facade rebar or embossed rebar. Why pressure reinforced, as is cost considerations can be used to more thin materials. This is certainly not the first choice for high quality speakers. Now requires high speakers generally used casting aluminium basin rack, light weight, high rigidity, easy processing into the desired shape. Since the speaker is installed vertically, as the Earth's gravity, particularly large magnet speaker, followed by a very large part weight, so in the basin rack side will increase to offset such as installation of deformation on the way, the best speakers from abroad are installed with the up and down, and will not be round can casually put 360 degrees. Domestic manufacturers of little note this HiFi, foreign Acura speakers put it as a business secret-this is why the same with the first poems in Western Asia, AustriaHorn of domestic manufacturers, but do not equally good sound speakers (of course this is not only the factors). But do the enthusiasts of speakers in the rear by the Board in the Horn, I do support has also been tested, but the sound quality of change I didn't recognize, and perhaps other factors more. Now also has to do with engineering plastic basin rack, but rigid or not, I think the short time does not become mainstream. Baritone Horn basin rack, in addition to supporting role or a small speaker, is closed, good quality speakers in this small speaker also will place the versamat to improve sound quality. Dust cover: goodies, the shape has a wide, why this is so, because apart from the dust, the Horn's beautiful and nourished by it. With Denmark Tanner as representatives of large dust cover has become part of the diaphragm may limit the sound. There is of course the soft dust cover being pressed not to, as to the quality improvement I beg to differ. Where in the course of 10 "carbon plastic polypropylene speaker because when in power will suck up dust cover and soft cover, only 8" at the diameter of the used software. Or the earliest yarn quality dust cover most scientific, air-lock is very small with dust, also not part of a voice, does not affect the design in accordance with good surface equation cone frequency response curve. Then there is the bullet, in foreign brand is represented in West Asia scholars, 97 years suddenly in domestic heat up as much of the sound quality improvement is benevolent see benevolence, Moses. To be sure, this kind of smooth surfaces must be somewhere in the space formed sound focus, the focus is always a good replay systems to avoid, like photography, avoid stray light points.
