Sounds from nature are the most inspiring things we experience through our life. What we try to achieve with ACCUVE is the reproduction of various real sounds.

 ACCUVE would like to introduce a new 2ch stereo loudspeaker system. We could develop a new and superior plane wave loudspeaker system reproducing 3D real sounds.

 Now let me help you experience the new world of real sounds.

ACCUVE

 Sounds are made by the flow of air pressure. Loudspeakers are equipment to generate the flow of air pressure. There are two ways to make sounds using the flow of air pressure: direct way affecting the flow of air pressure like lightening and indirect way generating the flow of air pressure by using the movement of an actuator like ordinary loudspeakers. To play back sounds close to an original one, it is essential to make the movement of an actuator similar to that of the original sound signal as much as possible. ACCUVE presents ideal loudspeaker systems which is capable of reproducing original sounds by adapting a newly-developed actuator to electrostatic loudspeaker structure.

 3D audio effects are a group of sound effects that manipulate the sound produced by stereo speakers, surround-sound speakers, speaker-arrays, or headphones. This frequently involves the virtual placement of sound sources anywhere in three-dimensional space, including behind, above or below the listener.
 The ACCUVE's 3-D audio is the spatial domain convolution of sound waves using a plane waves. It is not transforming sound waves to mimic natural sounds waves, which emanate from a point in a 3-D space. Only two plane wave ACCUVE's speakers allow trickery of the brain using the ears and auditory nerves, pretending to place different sounds in different 3-D locations upon hearing the sounds, even though the sounds may just be produced from just 2 speakers. It is dissimilar to surround sounds or a group of sound effects which using head-related transfer functions.

 ACCUVE's loudspeakers are characterized by a ventilative diaphragm for an electrostatic speaker. In the case of a non-ventilative diaphragm according to the related art, when a diaphragm is as close to a fixed electrode as it is affected by a ground effect, an increase in the pressure between the diaphragm and the fixed electrode due to the ground effect is directly transmitted to the non-ventilative diaphragm, which causes a reduction in sound pressure in a low frequency band due to the ground effect. However, according to ACCUVE 's embodiment, when the pressure between the ventilative diaphragm and the fixed electrode increases due to the ground effect, the effect of the increased pressure on the ventilative diaphragm is reduced by fine holes formed in the ventilative diaphragm. Therefore, the ventilative diaphragm is less affected by the sound pressure that is lowered due to the ground effect in a low frequency band than the non-ventilative diaphragm according to the related art.
