ABSTRACT:
A skateboard having an associated audio entertainment device is disclosed. The skateboard includes a forward truck and wheel assembly and a rearward truck and wheel assembly. A tail skid plate is preferably mounted at the rear of the skateboard on the lower surface thereof. An audio entertainment device, such as a radio receiver, is mounted to the lower surface of the skateboard between the rearward truck and the tail skid plate such that contact with the ground by the audio entertainment device is prevented and possible damage is minimized. The mounting position of the audio entertainment is preferably such that an associated speaker is mounted directly beneath one or more apertures in the skateboard so that the audio output of the speaker is directed upward. An acoustically permeable screen is utilized to protect the speaker and, in a preferred embodiment of the present invention, a guard plate is provided to further protect the audio entertainment device from inadvertent contact with the ground.
