USOUND TAYGETE 4.0 UY-R1040 User manual

3D HEADPHONES
The novel 3D headphone Taygete 4.0,
enables authentic 3D sound thanks to the
bridge of 16 MEMS micro speakers and an
electrodynamic woofer in each cup. It also
includes a unique algorithm which allows
real-time 3D sound. Its custom headphone
housing provides the position of the MEMS
speakers to reproduce user-specic spectral
cues that enable improved directional
hearing. It incorporates a USB soundcard,
DSP, DAC and ampliers.
The Taygete 4.0 headphones offers a USB-C
connector that is used for power supply and
data transfer. A computer can be used as
the source of the audio material.

BLOCK DIAGRAM
SETTING UP THE SYSTEM
The Taygete 4.0 headphone consists of a headband, two custom-built earcups and the built-in electronics.
Each earcup includes a 40 mm dynamic driver, used for reproducing signals in the lower frequency range
—below 2 kHz, and 16 MEMS speakers that reproduce the high-frequency content which is most relevant
for directional hearing.
COMPUTER SYSTEM REQUIREMENT
Computer with Windows 10 release number 1703 or higher — which supports USB audio devices class
2.0
VLC player
