Sounds Great Co. Ltd.(SG) is a design house focusing on Motion Microchip and their applications on Semiconductor Dynamic Speakers (SDS) and Semiconductor micromotors (SM).
SG aspires to take Semiconductor and Electromagnetic technology into acoustic and motor Industries. In acoustics, it enables an earphone bud equipped with 4 or even more SDS, covering twitter, mid-range, woofer, and subwoofer. It fundamentally transforms earphones into professional stereo.
SDS is also the best choice of hearing aids and personal sound amplification products due to quality sound reproducing and flexible sound customization on frequency and timbres. Additional amazing part is that this unique approach can avoid hearing impairment from earphones or hearing aids.
