Why can we reproduce delicate sounds with wireless earphones?

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.It is the sound quality that is the division of the price, but how many people understand what specifications the sound quality of the earphones improve?It's a bit core, but this time I will introduce the structure of the earphones and the elements that create high sound quality.

What is the structure of earphones in the first place?

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

Explain the mechanism that makes sound from earphones!

The earphones have a porcelain with a strong magnetic force called neodymium magnet and a coil with a structure with a wire wrapped around.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 cord, the magnet with this vibration version is shaken, and the air vibration becomes a sound.

Earphones are precision equipment that incorporates various materials

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

Further, since the material of the chord 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.

Expensive earphones have reasonable reasons for price

The difference between expensive earphones and inexpensive earphones lies in the sound quality, which is due to the fact that the material of the composed parts is different.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.Rosium is one of the silver elements, commonly called "rare metal".Because the electric resistance is low and the deterioration of the sound is small, expensive models are often adopted.

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 earphones sound sound?

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

Fly the sound source to the earphones wirelessly!?

Wireless earphones have the same structure of wired earphones and sounds.In a wired earphone, the sound source is an electric current and reaches the sound of the sound through the code, while the wireless earphones use Bluetooth to skip the data of the sound source.The earphones catch this data and sound.

Is it true that the sound is bad with Bluetooth earphones?

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

There is an earphone with good sound quality even in Bluetooth!

In recent years, Bluetooth technology has developed, and the size of data that can be skipped wirelessly has become larger and larger.In addition to this, due to the development of the earphone maker, the Bluetooth has also appeared as an earphone with sound quality comparable to the high -resolution class.

What are the recommended high -quality earphones?

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

Both powerful bass and clear treble![Audio-techNICA ATH-CKS5TW]

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

A unique earphone using wood is particular about sound quality [JVC HA-FW03]

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 wooden wood is not only for the impact of the appearance, but also to suppress unnecessary vibration.It faithfully expresses the rich amount of information of high -resolution sound sources, and will deliver a pleasant and delicate sound to your ears.
