Retail Audio POP Case Study: Headphone & Speaker Demonstration Bench for Panasonic

The retail fixture is made of CNC (Computer Numerical Control) machine from flat metal sheet adding spray painting to customize color. The user interfaces include LCD panel, light conductive plate, buttons and line-in cable. 3 button types are available, capacitive touch button( with easy user engagement ),  rotary button, LED illuminated push button.

The light conductive plate is made by an acrylic plate with laser-made pitch matrix to spread the light from LED strips at side to the whole plate eventually. Power supply is from power port on mother board.

Rotary buttons are used to adjust volume in a more natural way, and it is optional to have rotary buttons with “push for selection” function for track or output channel switch.

The headphone & speaker demonstration gets personal, it supports users’ personal audio device line-in to listen to their own favourite songs for easy comparison.

GPIO port for button controls and power port for lighting power supply.
