Why can we reproduce delicate sounds with wireless earphones?｜ @Dime at Daim

Earphones with a wide range of prices, from those that can be purchased at a 100 yen shop to those that cost more than 100,000 yen for high ones.It is the sound quality that is the division of the price, but how many people understand what specifications of earphones improve the sound quality?It's a bit core, but this time I will introduce the structure of such earphones and the elements that create high sound quality.

What is the structure of the earphones in the first place?

First of all, I will explain what the earphones have in the first place and how they sound.

The earphones have a magnet with a strong magnetic force called a neodymium magnet, and a coil with a structure with a wire wrapped.The basic principle is that a metal vibration version is attached to this magnet, and when the sound source flows as an current from the code, the magnet with this vibration is shaken, and the air vibration becomes a sound.

The air vibration that can be shaken by the magnet is prepared by the cavity, material, net, etc. in the earphones, and eventually becomes a sound and reaches the user's ear.Since these materials and structures vary depending on the manufacturer and model, each sound is different.

Further, since the material of the cord part is mainly used by silver and copper, if the quality is low, the impurities are mixed and the noise is mixed in the sound.

The difference between expensive earphones and inexpensive earphones lies in the sound quality, which is due to different parts of the components.Even if the material of the cable is the same, silver, gold, tin, etc. may be used as plating to prevent the sound from deteriorating.

Gold, nickel, rhodium, etc. are used for the plug and connector part, which also affects the sound quality.Rhodium is one of the silver elements, commonly called "rare metal".Because the electric resistance is low and the sound deteriorates, it is often used for expensive models.

Copper is standard for inexpensive cables, but copper is easy to pass through bass.Conversely, silver is suitable for delicately reproducing the high range, and this is one of the factors that high -end earphones can reproduce delicate sounds.

Why can the wireless earphone sound sound?

What we have explained so far is the structure of wired earphones.So why does the wireless earphone generate sounds?

Wireless earphones have the same structure of wired earphones and sounds.In wired earphones, the sound source becomes an current and reaches the sound of the sound through the cord, while the wireless earphone uses Bluetooth to fly the sound source data.The earphones catch this data and sound.

I often hear the theory that "Bluetooth earphones have worse sound quality than wired ones."This is due to the process of compressing and sending the sound source when the Bluetooth earphone is flying a sound source to the sound.If you send a compressed file to the other party when sending data on a personal computer, it will be easier to understand that it may be garbled.Conversely, wired earphones are said to have good sound quality because they do not require this compression work.

In recent years, Bluetooth technology has developed, and the size of data that can be wirelessly fly has become larger and larger.In addition to this, due to the development of the earphone maker, Bluetooth has also appeared in the high -resolution class earphones comparable to the high -resolution class.

What are the recommended high -quality earphones?

From here, let's introduce recommended high -quality earphones.

Audio-Technica's "ATH-CKS5TW", which has many products in each price range, is a completely wireless and recommended earphone.A metal with different hardness is used in the vibration plate, and a powerful heavy bass and a clear middle and high notes can be reproduced.Equipped with a large -capacity battery that can be played for up to 15 hours, a 3D loop was adopted in addition to a thin and soft earpiece of silicon material, and it was stuck in the difficulty of removing.

JVC's "HA-FW03", which uses a lightweight 10mm wood dome that is thinly reduced to 50 µm, is a recommended wired earphone for high-resolution compatible wired earphones.The wooden vibration version reproduces the spread of natural and beautiful sound like stringed instruments and pianos.

The sound of the driver with a sound is made of wooden material not only because it looks impact, but also to suppress unnecessary vibration.It will faithfully express the rich amount of information of high -resolution sound sources and deliver delicate sounds to your ears.
