ABSTRACT:
A media playing device includes a housing with a cylindrical end and a middle portion, a knob, a PCB, a cover, and an attachment means. The end has a reduced diameter with respect to the middle portion, thus forming a step, and has an opening. The knob has a cylindrical inside surface with two protrusions and is attached to the housing with the two protrusions being located within the opening. The PCB has a micro controller unit (MCU) and at least one switch. The cover is detachably attached to the housing and together with the step limit the axial movement of the knob. The attachment means is used for attaching the cover to the housing. When the knob is rotated to a position where one of the contacting protrusions contacts the switch, the switch is activated and sends a signal to the MCU, the MCU executes an operation in response to the signal.
