PURPOSE:To reproduce impressive music by mounting at east one speaker on at least one disk of a wheel so that an audio system can be easily carried. CONSTITUTION:A rim 9 is held through spokes 6 on a hub 8 held by a front fork 7 and a speaker 4 is mounted by a screw 11 to a disk 2 fixed between the hub 8 and rim 9 by a bolt 10. The spokes 6 at the speaker 4 portion are removed. The speaker 4 is of an extremely thin type using an inverted conical vibration plate. A sealing agent 12 is applied to gaps between the disk 2, rum 9 and hub 8 for ensuring air tightness and an electric signal is input from a plug 13 fixed to the disk 2 through a lead wire 14 to the speaker 4. Thus, a large-sized speaker system can be mounted so that impressive music or the like can be reproduced. |
