R&D ACHIEVEMENT

Strengthen global competitiveness through continuous R & D achievements

iCubes Co., Ltd. has developed key technologies in the field of sound technology through continuous R & D investment.
As the result, we launched bone-conducted hearing aids and clear stereophonic sound transfered earphones based on differentiated technology, therefore, we are growing into a leading company in the global sound technology market both domestically and internationally.

02 Certificate

- Implement wider frequency and rich bass sound by applying tweeter and woofer which is customizing own technology.
- Improvement of high-frequency and low-frequency characteristics through structural improvement.
- Next-generation earphones optimized for 3D music, movies and games.
- No Coil, No Attachment, Using Piezoelectric
- A bone conduction type that delivers bone as a medium without delivering sound directly to the eardrum.
- Hearing assistance device (20 ~ 22,000Hz) that can listen to music with wide frequency band compared to other hearing aids (20 ~ 8,000Hz).
- Apply hard PCB type which can be mass-produced by improving existed copper coil type.
- Abundant acoustic characteristics compared to domestic and overseas competitors
  (Improve bass and treble characteristics)
- Ensures high reliability compared to other products by applying heat and moisture resistant diaphragm.

03 Product Development Achievement


Product Development Achievement
Solid-conduction speaker	Hearing aids, hearing protection earphones	A bone conduction type that delivers bone as a medium without delivering sound directly to the eardrum.
		Designed for available to listen sound who have injuries such as eardrum and middle ear ossicles if there is no damage to the auditory nerve.
		Hearing assistance device that can listen to music with wide frequency band compared to other hearing aids.
		Differences from existing bone conduction products: Use a piezoelectric without a coil.No side effects such as headache or dizziness due to smaller vibration width compared to existing products.
	Solid conduction earphone & throat microphone	The solid conduction earphone has a function to prevent hearing damage
		The solid conduction earphone products block ambient noise and clearly hear the other party's speech.
		Throat microphones are developed for ambient noise is blocked, and only the speech delivery as work only with vibrations of the vocal cords
Multiway Earphones	Bluetooth earphone	Implement wider frequency and rich bass sound by applying tweeter and woofer which is customizing own technology.
		Improve characteristics of treble and bass region by modifying structure (realize clear high-frequency range)
		There is no sound accumulation because the bass and treble are structurally output in different paths and it performs excellent spatial and 3D sound.
		Next generation earphone products optimized for 3D music, movies and games
Slim speaker	Bluetooth speaker	Apply hard PCB type which can be mass-produced by improving existed copper coil type.
		Abundant acoustic characteristics compared to domestic and overseas competitors (Improve bass and treble characteristics)
		Patent registration of new type of magnet structure and special diaphragm
		Ensures high reliability compared to other products by applying heat and moisture resistant diaphragm.
