Smart Construction

The device holder adapts to any mobile phone size and ensures an upright straight position. The device can also be charged while in usage. The layer is kind of a perpendicular wall adjusted to the length of the bamboo cylinder. In the same time the phone is kept in a distance to the cylinders ground due to the fact that most devices have the speakers on their bottom side. With the right distance to the ground, the sound that leaves the device can spread throughout the pipe and is amplified in a warm and clear sound which is truly impressive.

The drawing on the left illustrates the simple but effective construction. See how the inner layer is held in an optimal proportion to the main diameter to keep the phone in a perfect position.
