AAS technology helps to enhance dynamic bass effectiveness of speaker system. It consists of active driver, sealed cabinet and passive radiator. Its aerodynamic theory is that: during active driver working, it likes an engine and pushes air in sealed cabinet moving. This air works like spring to push movement of passive radiator. The passive radiator actually performs as a low frequency filter so that bass of speaker system enhanced. Also bass enhanced by AAS system is without noise coming from port of traditional speaker design.
Special driver design: Neodymium driver to meet limited cabinet and high driver sensitivity needed.
Passive driver design: durable design
PLL (Phase-locked loops) technology is widely used in radio, telecommunications, computers and other electronic applications.
A phase-locked loop is a control system that generates a signal that has a fixed relation to the phase of a "reference" signal. A phase-locked loop circuit responds to both the frequency and the phase of the input signals, automatically raising or lowering the frequency of a controlled oscillator until it is matched to the reference in both frequency and phase.
And a digital PLL FM IC (integrated circuit) provides a complete phase-locked-loop building block in digital processing way. All data is treated in digital method which can reduce signal noise and also increase capability of anti-interference.
