70b of the right side plate 76 so that a sound is emitted toward the cabinet portion 62 (see FIG.
6), and the first exciter The passive diaphragm 76b, which receives the sound pressure of the
diaphragm section 75a that vibrates in a division manner by 6 via the box chamber 70b, divides
and vibrates in a direction that is exactly opposite to the direction (left direction) that emits the
sound of the diaphragm section 75a. It may be configured to emit sound in a direction toward
the cabinet side (right direction). On the other hand, the box-like speaker 73 may be made rigid
so as not to vibrate by, for example, increasing the plate thickness so as not to vibrate the portion
of the right side plate 76 facing the box chamber 70b.

speakers 72 and 73 are communicated with each other through the communication passage 79.
The speaker device 71 uses the divided vibration of the diaphragm by the exciter, so that the box
chambers 70a and 70b can be communicated with each other without considering the phases of
the box chambers 70a and 70b. Therefore, there is no limitation in design considering the phase,
and the degree of freedom in design is expanded in providing the communication passage 79 for
connecting the adjacent box chambers 70a and 70b to each other.
