HPSD E70 
SIMPLE SPEC

HPSD E70 Features

We developed the world's first Magneto-Static Method technology.
It allows you to reproduce crisp, clear, detailed ultra high resolution sound.

 

- It delivers a lively space and thrill to the listeners as if they were at a live concert.

- Even the slightest sound is not buried.
  In addition, the bass, mid, and high frequencies of all bands are heard in fine, clear separation.

- Provides very clear and accurate sound.

- Excellent for reproduction of the original tone of the signal.

First modular variable earphones that can be disassembled and combined.

- You can exchange and change the color and sound pattern.

 

- You can easily repair the damaged part.

 

- It is possible to change the design using two types of capsules.

CORE TECHNOLOGY

MAGNETO-STATIC DRIVER

RADIAL WING SHAPE MEMBRANE

MS DRIVER FEATURE

The ultra-light and flexible special diaphragm drives ultra-high speed by itself using pure magnetic field, so it responds instantly to very fast and complex signals and is suitable for ultra-high resolution sound reproduction.

Since the magnetic field is a single conversion path that vibrates the diaphragm directly, the distortion and loss of the original signal are very low, which is excellent for reproducing the original sound.


The sound produced by the Magneto-Static Driver is very fine and even small sounds are not buried in loud sounds, so you can listen at low volume. It is also good for hearing protection.

 

You don't need a high voltage amplifier, which was a requirement for Electro-Static, so you can easily enjoy super high resolution sound anytime, anywhere.

PRINCIPLE

At the top and bottom of the diaphragm, a pair of permanent magnets (21, 22) and coils (11, 12) are arranged so that they do not come into contact with the diaphragm (30).


The diaphragm(30) is electromagnetized by the electromagnetic force of the coils(11, 12) placed above and below, and reacts with the magnetic force of the permanent magnets (21, 22) in the state where the weight of the coil is excluded. This allows the diaphragm(30) to drive itself at a very high speed, allowing it to react quickly and accurately to electrical signals.


The result is very detailed and detailed sound reproduction in all sound spectrums, resulting in high quality sound and ultra-high resolution sound.


Since the magnetic field is a single conversion path that vibrates the diaphragm directly, the distortion of the original signal is very low, which is excellent for reproducing the original sound.

Comparison with existing technology

No high voltage drive amplifier is required.

RADIAL WING SHAPE MEMBRANE

Made of hysteresis loop material that is extremely sensitive to small electrical signals and very fast magnetic field changes.


RWS diaphragms are made of high-tech new material with high density and elasticity.
Its very low mass, high permeability, high saturation magnetic flux density and very low residual magnetic flux density make it very quick to respond to electrical signals, making it ideal for realizing ultra-fast vibrations and well suited for reproducing ultra-high resolution sounds.

The magnetic resistance of the RWS diaphragm material is very low and the electrical resistivity is very high, so it is protected from distortion caused by heat loss and eddy currents, resulting in very clean and delicate sound.

 

RWS diaphragms are low in mass and very thin, but nevertheless have very high saturation flux densities, resulting in high sound conversion efficiency.


The special diaphragm of the MS driver is made very thin and light for ultra-fast maneuvering and designed in the form of a radial wing with an open center.
This type of diaphragm is sensitive and precisely responds to even the
smallest signals, so that even small sounds mixed with loud sounds can be reproduced naturally and delicately.

HYBRID FOR A WIDE FREQUENCY RANGE

MS DRIVER FOR ULTRA HIGH RESOLUTION

TDB DRIVER FOR DEEP BASS

Coaxial structure layout for delivering high resolution sound in a wide frequency range directly to the listener's ears without phase interference.

Powerful sound with 4 magnets

The HPSD E70 uses hybrid speakers that combine two theoretical technologies into one.

 


- Coaxial combination of Magneto-Static and Electro Dynamic drivers minimizes the phase interference of the sound emitted by both speakers. This results in a wide range of sounds that blend naturally and precisely and ideally.

 

- The MS Driver (MagnetoStatic Driver) is responsible for the super high resolution range, and the DB Driver (Deep Bass Driver) is responsible for the bass, resulting in deep, rich bass and a wide range of super resolution sounds.
