Abstract: A speaker system is provided having a primary speaker module configured to communicate with an external audio device and having a speaker output face and a back surface, and a secondary speaker module in signal communication with the primary speaker module and having a speaker output face and a back surface. The primary speaker module and the secondary speaker module combine in at least two configurations, a first configuration in which the primary speaker module and the secondary speaker module are connected at their back surfaces and their respective speaker output faces face opposite directions, and a second configuration in which the primary speaker module and the secondary speaker module are side by side and their respective speaker output faces face substantially the same direction.

Abstract: A sport board system is provided, the system having a sport board deck having a bottom surface, a front end and a rear end, a rear wheel assembly fixed to the bottom surface adjacent the rear end, and a fixation structure for a wheel assembly at the front end. The fixation structure has a notch passing through a thickness of the sport board deck, fixation rails parallel to a length of the sport board deck, and a locking mechanism at an end of the notch.

Abstract: An expandable wireless speaker system and method is disclosed. The speaker system comprises a center module and at least two or more speakers. The center module has a unique identification number and has mechanical connections on at least one side. The center module is configured to receive an external device, wirelessly or directly connected and has a transceiver configured to scan for an unused channel and transmit audio. The speakers each have a mechanical connection on either side to connect to the center module or the other speakers. The two or more speakers are configured to scan the communication spectrum for the center module's unique identification and when the two or more speakers locate the center module's unique identification, the two or more speakers pair with the center module to receive audio. The communication spectrum can be a wireless channel such as 5.8 GHz or the FM radio spectrum.
