Battery is ideal power source for audio product. It is a clean power, free of noise and no hum noise induced. Lithium battery has high instant current, excellent load regulation, those are key factors to deliver punching sound.
Design a high efficient low voltage amplifier has lot of constraints. Our 5 years work get problems resolved, a low current consumption speaker can have high quality sound. We build the longest play time battery speaker ONEmini, it has 100 hours play time.
We believe simple hardware and software can retain the original sound nature, error-free signalling flow from source to speaker, that can reproduce the true music sound. Speaker should not colourize music, never shift sound balance, output the sound as of originate as possible. Sound should be come with the most natural, long listening without fatigue.
How to build a handy size speaker to reproduce big sound stage, enclosure design is the most challenging. Enclosure must be strong enough to sustain high sound pressure. Circuitry should be as simple as possible. Speaker drive should have high efficient.
We developed all software modules : DECT protocol stack, WiFi interface, sound processing and hardware controller. Software modules are combined to a single firmware, loaded in a single chip, and run on a multi-core processor.
The ONEdonlge is a standard USB audio device can support stereo and 5.1 surround. Very small in size, but it has highly concentrated and sophisticated firmware. It is a HiFi quality transmitter, just plug and play.
