Conventional HiFi audio system is bulky and complicate. It is built by many devices, accessories and cables. You need to match them up carefully, make sure every device and cable are good quality, spend a lot of money and time, of course you will have good sound.
ONEaudio use new sound engineering concept, solve root problems in fundamental design principle, got a sensational sound experience. A wireless speaker can reproduce sound better than wired speaker.
Photo show a conventional HiFi set is so complicate, bulky, lot of cables, many devices, …. and space demanding !
New audio set is simple, compact in size, free of wires, separated mono-block, …. and space saving !
ONEaudio speakers are more advance. Our speakers can adapt sound source nature, then reproduce sound match to sound source : stereophonic music sound, theatre moive sound and natural TV sound.
Transmission line distortion (conductive loss, phase shift, non-linear group delay, overshoot, thermal noise, EMI pick up, ….) is inherent in cables, high quality cable can reduce distortion but can’t remove. The way to solve is no cable.
Main supply on wall outlet is dirty power source which is source of sound pollution. Battery is perfect power supply, clean and pure power source, it can deliver high instant current to support high dynamic sound.
Analogue devices usually have cumulative noise and distortion problem. More devices will induce more distortion. Change to digital design can prevent signal quality degradation, avoid noise pick up, eliminate coupling distortion and remove phase shift.
Use single amplifier for full audio band amplification usually has serious TIM distortion. TIM distortion is reaon of lacking music details in high dynamic play. Lower amplifier’s feedback can reduce TIM distortion. By splitting audio band into high range, mid range and low range can narrow down amplifier operation range, attain lower amplifier feedback as well as TIM distortion improvement.
Crossover filter inside wired speaker intrinsic having phase error problem, overlapped mid range band spread on crossover point is distorted after acoutic mixing of woofer and tweeter, mid range sound is blur. By use of digital linear FIR filter, woofer’s low frequency sound and tweeter’s high frequency sound are guaranteed in-phase, together with acoustic correction on tweeter axial offset, phase error distortion is completely removed.
Each ONEaudio speaker inside is a highly integrated multi-processor SOC chip, which is loaded an all-in-one firmware. Components are minimum, signal path is optimized, on board battery provide direct power connection, speaker wire is the shortest, no noise pick up, and never has ground noise hum problem.
ONEaudio wireless speakers are working on interference free 1.9GHz frequency band, each connection is on exclusive channel ensure no radio devices jam.
All ONEaudio speaker are separated, from stereo to surround set, no bridging cable, no speaker cable, no power cord.
Reason is poor channel synchronization between left and right speaker. DECT protocol has accurate timing characteristic, left and right speaker channel synchronization can be controlled down to 0.000001 second, 20 times better than WiFi.
Reason of fatigue sound is poor time jittering induce “shaking” sound background. ONEaudio give up digital control mechanism and go back to linear control, our speaker can achieve time jitter less than 0.02ppm, 100 times better than WiFi speaker.
ONEaudio speaker can reproduce airy and gentle high frequency tone. Each speaker equipped with 2 pieces DSP for upscale low resolution sound to HD sound. You can hear sexy female vocal, rich harmonics violin and harmony piano.
ONEaudio speaker has unbelievably long play time, ONEmini speaker can play 100 hours music or 50 movies. You need to do charging every 2~3 months.
