PURPOSE: To improve operability when a circuit board is fitted on a body and is smoothly attached to or detached from a flexible board. CONSTITUTION: A speaker placed in a body 1 is electrically connected with a circuit board 4 fitted on the body 1 via a flexible board 2. The flexible board 2 has U-shaped band bodies 6 that are not overlaid on each other, and under a condition that the circuit board 4 is fitted on the body 1, the U-shaped band bodies 6 are folded without almost giving bending returning ability to the circuit board 4. |
