1. Paper cone
In the speaker industry, paper cones are the most commonly used and common type of cones, and the related research and development technology is also very mature.
The reason why paper cones are so popular is, firstly, that the sound of the cones is natural and flat, and the timbre is bright and neutral. It can not only reflect the soft style, but also be lively and dynamic, which is in line with the listening sense of most people; secondly, the material of the paper cones It is easy to obtain and the cost is relatively approachable.
As a speaker cone material, paper cone has ideal energy conversion efficiency and outstanding damping characteristics due to its light weight. Therefore, although the cost is not high, it can still create a pleasant sound, and therefore has become the preferred choice for many speakers, even The first choice for classic models with less fever, such as the American ATOMIC top HI-END mid-bass APX6.5, which also uses a special paper cone diaphragm.
Of course, "paper cone" is just a common name. The "paper pulp" used by different brands to make paper cone diaphragms often has their own exclusive formula, which also forms their own different styles and timbres.
As for the shortcomings, the paper cone is sensitive to temperature and humidity. When exposed to high temperatures or moisture, the work efficiency and sound quality will deteriorate. These situations are more common in cars, so this also requires that the speakers be installed during installation and construction. , heat insulation, waterproofing and moisture-proofing must be done in advance.
2. Ceramic basin
The sound of the ceramic cone is full of enchanting magic. In terms of timbre, ceramic cones have excellent detail expression and can reproduce tiny details. At the same time, they are also dynamically thick and full, and have a very clear appeal and impact; in addition, ceramic cones The sound reproduction of the cone has a very outstanding sense of realism. For audiophiles who pursue realistic reproduction of sound, ceramic cone speakers are undoubtedly full of temptation.
Of course, ceramic cones are affected by the material and have higher requirements for the working environment. The yield rate in production is also slightly lower than that of paper cones. Therefore, there are relatively few speakers with ceramic cones, but there are also many speakers that pursue realistic reproduction. Ceramic cones are deliberately used. For example, Gypsy Sound's GS102 unit uses ceramic cones, which makes this 3-inch unit have outstanding playback performance, with transparent and deep sound. It can not only be used as a midrange unit, but also as a mid-range unit. Full-range units can also compete.
3. Wool fiber basin
Wool cone is a composite fiber diaphragm produced by infiltrating wool fiber into paper pulp based on paper cone. Compared with common paper cones, wool cones not only continue the advantages of paper cones in terms of lightness and stretch response, but also incorporate the softness, smoothness, elasticity and toughness of wool fibers. The sound is smoother and more graceful, and the listening experience is more romantic. Beauty.
The expressiveness of wool basins in the mid-frequency and mid-high frequency bands is full of intoxicating rich musical charm, and it is easy to create the so-called "fever smell"; however, the cost of raw materials is also higher, and the yield rate is also higher than that of common paper basins. Low, so the wool basin can usually be seen on audiophile-level and appreciation-level speakers. Gypsy Sound's classic set of speakers - Crystal GS1, in which the woofer unit GS106 uses a wool basin, is recognized as a masterpiece of a generation of car speakers with extremely high cost performance.
