PROBLEM TO BE SOLVED: To provide a board speaker configured so as to further efficiently vibrate a sound generation board, as a vibration forming mechanism as compared to prior types.SOLUTION: One end portion of a leaf spring with a magnetic circuit part being fixed in the other end portion is mounted on the surface of a sound generation board. The other end portion of the leaf spring is provided substantially in parallel with the surface of the sound generation board so as to transfer the vibration which is generated in a voice coil, in relation to the magnetic circuit part, and to a direction perpendicular to the surface of the sound generating board. Thus, the effect of transferring the vibration from the voice coil to the sound generating board can be improved further. |
