There are many brands of dynamic earphones, and they are the most common and mature earphones with mature and stable performance on the market. When it comes to dynamic earphones, we should all be familiar with them. Most of the earphones that are common in squares and stations, and professional fever earphones that cost tens of thousands of dollars are mostly dynamic earphones. The price of moving coil earphones whose sound quality has entered the HIFI level is generally more than 200 yuan, and moving coil earphones are divided into single moving coil and multi-moving coil.
Single moving coil
The single moving coil earphone is the most common earphone. Its driving unit is a small moving coil speaker, which is driven by a voice coil in a permanent magnetic field to vibrate the connected diaphragm. Moving coil earphones are more efficient, reliable and durable. Generally, the larger the diameter of the drive unit, the wider the frequency response range; the smaller the unit, the better the resolution.
When choosing a single moving coil headset, what needs to be considered is the drive unit. That is: the larger the diameter of the drive unit, the wider the frequency response range; the smaller the unit, the better the resolution. (For frequency response and resolution, you can refer to the article "Do I need to look at the parameters when buying HIFI headphones"). Single moving coil headset technology is relatively mature. In terms of low frequency, the dynamic coil has a great advantage in volume, and it is easier to show the dynamic sense of the music (as the saying goes, "dong times hit times"). A good dynamic earphone handles all aspects very well, with three-frequency balance, no interference with each other, and a good atmosphere. It is the best choice for pop music. 21% of users will choose earphones below 200 yuan; 41% of users will choose earphones priced between 200 and 350 yuan; 18% of users will choose earphones above 500 yuan!
Multi-moving coil is not difficult to understand. Multi-moving coil earphones are composed of multiple moving coil units, mostly in parallel. And it is not necessarily better than a single moving coil. Multi-unit sound cavity, the cohesive ability may be unnaturally balanced, but multi-unit has its advantages, such as a wider frequency response range and a very exciting hearing.
When choosing a multi-moving coil headset, we learned that the frequency response range of a multi-moving coil headset is usually wider than that of a single-moving coil headset, around 18Hz-25000Hz. In the article "Do you want to look at the parameters when buying HIFI headphones", it is mentioned that the range that human hearing can reach is about 20Hz-20000Hz, and the current mature headset technology has reached this requirement. However, the frequency response range of the multi-motion coil exceeds the normal value of 20-20000 Hz for the human ear, and the higher part is inaudible to humans, but this does not mean that the frequency beyond this range is not perceivable by humans. Therefore, the frequency response range of multi-moving headphones is better than that of single-moving headphones. The specific performance is that the dynamics are greatly improved relative to the single-moving coil. However, problems such as abruptness, bluntness, unnaturalness, and turbidity in a certain frequency band have also appeared. Whether it is good or bad depends on the manufacturer's frequency division technology. Fans who are looking for a strong rhythm and excitement can consider starting with a multi-moving circle; those who like natural and smooth should choose a single-moving circle. For the choice of multi-motion circle: 46% of users will choose the price below 300 yuan; 26% of the users will choose the price between 300 and 600 yuan; a few 5% of the users will choose the price above 600 yuan.
To choose a good dynamic headset, the first thing we must consider is the hardware of the headset. From the sound principle of the moving coil, we need to understand that the sound quality of the moving coil earphone mainly depends on the material of the diaphragm and the material and structure of the cavity in the hardware. The magnet and the voice coil mainly determine the driveability of the earphone. The design of the cavity plays a vital role in the sound performance of dynamic headphones.
Finally, whether the headset is good or not, it is still to use your own ears to have a trial experience. Headphone enthusiasts want to get more moved from the feelings expressed by music, so headphones that can make you feel like an electric shock and goose bumps are a good headphone.
