During air flight, passengers often use entertainment system to enjoy the journey. However, the traditional personal headsets device used with flight entertainment system came out some cumbersome due to vary inconvenience. This proposal is to propose a solution of current sound system problem occurred in aircrafts, it will make passengers be more convenient, the system which is going to be proposed is called directional sound system.

But, we always take it for granted, taking off earphone for giving way or for talking with other passengers and re-pack the earphone by bag. However, do we have alternative? Bluetooth earphone maybe can be a selection, but, there is still something on your head and not really convenient at all. It’s behooved to implement a new solution- The Directional Sound System. how will aircraft makers take the advantage of DSS? And how will they conduct this system? As the same as the LCD display, DSS can be modularized to be a component/or a brick and be embedded in each front seat. The modular component can be combined with current audio-video system, sound power of every seat can be
