Airflow Control Unit

or ACU, allows user to control the sound of the dynamic driver via interchangeable filters. The ACU controls the amount of air in the rear chamber of the Dynamic driver. 

How does it work? 

Dynamic driver in a hybrid IEM design works in the same way as it's working in a HIFI speaker. The internal structure of the HIF speaker is part of the acoustic design as the total volume of air in the speaker chamber affects the sound of the dynamic driver greatly. In an IEM enjoyment, the shell size vary depends on each individual users' ear geometry therefore the total volume of the air in the shell changes from one and another. If we just dump the dynamic driver in the shell, like what other brands are doing, we will not be able to make sure that each and every custom IEMs will sound the same. The universal demo shell is always much smaller than the actual custom, so there will always be a great difference between the demo and the actual custom IEM.

The solution. 

To completely eliminate this problem once for all, we calculated, simulated and came out with an optimized, fixed volume for the rear chamber of the dynamic driver that we know and sure that will always sound the same for each and every pair of the hybrid IEMs*. With the ACU, what you hear from the universal will be what you hear from your custom*.

Cross Sync Uniphase

or CSU,is the fundamental method and techniques of IEM sound design. 

The problem

Balanced armature driver is highly inductive. Traditional passive electronics filters in the multi-driver crossover system introduces phase shift at crossover point by 90 degrees to 180 degrees. As the analogy signal coming from the DAC to the IEM is an AC signal, out of phase electronic signals will produce out of face soundwaves from the drivers. Converting the out-of-phase issue from electronic (electronic signal) domain into analog (soundwaves) domain. It results multiple drivers cancelling each other at crossover point and cause a big dip on the frequency response together with a dirty Fast-Fourier Transform analysis. 

The Solution

CSU utilizes both electronics filtering design and acoustic path design to create crossover system including passive electronic low pass filter, band pass filter and high pass filters. And the acoustic filters help to eliminate unwanted frequency from the driver and smooth the frequency response. By adjusting the placement of each driver, soundwave phase cancellation at crossover point can be eliminated and all drivers will produce synchronized soundwaves at the same time. Resulting the drivers to produce wider frequency range improve sound pressure level at super high frequency range. And for the users’ experience, they will be able to hear more detail, full-bodied and engaging sound with a nature sound stage.

In summary, CSU conjugating frequency domain and time domain into one synchronized system with phase aligned multi-driver IEM crossover system. Delivering an unparalleled coherent and natural sounding IEM design. 

* Hearing difference caused by individual ear canal geometry, hearing loss, different types of ear tips, run-in time is not discussed in this case.
