An excellent HiFi speaker with a perfect high frequency is often not enough. To achieve a classic, the extra points on the low frequency can always achieve a contrarian overtaking. HiVi Hivi M3A is such a product, what is the status of its reference flagship in the cloud era? In addition to the magnetic field treble and the forward-looking acoustic design, the large-diameter long-stroke 6.5-inch woofer on the bass is the crowning touch of this case. HiVi hivi M3A speaker with ultra-light, high-strength integrated Kevlar fiber material, why is it that the sound is very fast and flexible at low frequencies? The reason why the 6.5-inch woofer is the most suitable choice, this is inseparable from the market positioning of HiVi Swans M3A speakers, it is often used in the home living room environment with ultra-thin large-screen TV and HiFi music listening, its acoustic space is closer than the near field The multimedia desktop environment is much larger. To meet the low-frequency sound pressure output and low-frequency extension, it will naturally freeze above the 6.5-inch woofer. In addition, the unit design must take into account the various parameters of the speaker unit and pursue an overall balance between the contradictory parameters. The biggest impact on sound quality is the speaker diaphragm. HiVi uses the most expensive iron-gray Kevlar bullet-proof fiber material, which may answer the reason why HiVi's top 6.5-inch large-caliber woofer sound quality is so good. In theory, the speaker diaphragm has three most important parameters, namely material density, material stiffness and damping characteristics. These three encounter the same trouble, that is, these three parameters contradict each other. We may wish that the density of the diaphragm material is as small as possible, because the material with the lighter vibration quality is more favorable for the vibration of the vibrating plate and the transient characteristics are better. We may also hope that the rigidity of the diaphragm is better, that is, the Young's modulus of the Young's modulus is higher, which can reduce the influence of the diaphragm splitting vibration on the sound quality. Ideally, we do not want to split the vibration phenomenon, and hope that no matter at any The frequency diaphragm is an overall synchronous motion. We also hope that the internal damping of the diaphragm, that is, the energy absorption inside the material. The ideal vibration of the diaphragm is that the diaphragm should be activated immediately when the voice coil is activated. When the voice coil has no audio current, the diaphragm should stop moving immediately. Considering the vibration of the diaphragm before and after, the diaphragm must be internally damped. (This is also one of the reasons why HiVi Hivi does not like to use metal diaphragm for woofer, because in addition to rigidity, density and damping are not good), in order to solve the contradiction between the three, the only way to crack is on the material. Fortunately, HiVi Huiwei successfully discovered the material of Kevlar bulletproof fabric fiber. Since the early 1990s, HiVi has been the first company in China to manufacture a bullet-proof fiber speaker unit. At the time, the HiVi model was a K-series speaker, and K was derived from the English word for Kevlar bullet-proof fabric. Many enthusiasts may not know. In the 1960s, DuPont developed a new type of aramid fiber composite material with the registered trademark Kevlar. The new material has low density, high strength, good internal resistance and toughness, high temperature, and its strength is 5 times that of the same quality steel, but the density is only one-fifth of that of steel (Kevlar density is 1.44g per cubic centimeter, steel density). It is 7.859 g per cubic centimeter). Because Kevlar materials are tough and wearable, they have special skills that are invulnerable. It is called "armored guardian" in the military. According to tests, its ability to withstand armor-piercing bullets is much better than FRP and steel armor, and Kevlar is the core material for armor-resistant garments. Therefore, this high-strength and internally damped bulletproof fiber material can quickly absorb the excess vibration energy of the sound, ensuring that the sound is more delicate and clean, which explains why Swans uses Kevlar bulletproof fiber material for its top speaker unit diaphragm material. The speaker unit is a complete balanced vibration system, so the good vibration plate should be well matched with other components. The fatigue-resistant long-stroke rubber folding ring and high-consistent centering piece make the unit have excellent displacement stroke and dynamic stability. The central bullet phase plug can correct the IF response of the unit, making the IF frequency wider and flatter. The long-stroke linear displacement design provides a more powerful bass output, ensuring a linear vibration range at high power of the diaphragm, and the low frequency is powerful and powerful, and the frequency extends up to 44 Hz. Note that the low frequency extension of the speaker is not as low as possible, because the excessive low frequency extension not only makes the sound soft and turbid, but more importantly, makes the woofer work in an incapable range, resulting in low frequency audible distortion and saturated hum. We often say that if the speaker unit does not put this band out, it is best to cut it directly with a high-pass filter, which can improve the effective low-frequency sound pressure output, and obtain a more vivid and low-frequency playback effect. This view is in professional monitoring. The field is widely used, which is one of the advantages of active speakers versus passive speakers, because the active electronic filtering system allows each speaker unit to work optimally. Thanks to the application of Kevlar, the material contradiction between material density, material rigidity and damping characteristics is solved, giving the HiVi Swans M3A 6.5-inch woofer the perfect bass performance, also because of the 6.5-inch woofer. Points, combined with the magnetic field belt treble perfect high-pitched output, the achievement of HiVi Hivi M3A cloud era reference level flagship status. A new experience of true wireless
