Abstract: To provide “acoustic system” for obtaining required drive force with low power, first voice coil greater in height dimension than gap in which magnetic flux propagates and second voice coil equal in height dimension to gap are provided such that their height-direction centers coincide. When amplification factors of audio signal applied to first and second voice coils are defined as A1 and A2, respectively, A1 is set to 0 and A2 is set to A2st when detected displacement of loudspeaker is within displacement range where second voice coil is at position where it can properly interact with magnetic flux in gap. A2 is set to 0 and A1 is set to A1st when detected displacement is within range where A2 is not set to A2st. A2st is smaller than A1st. Ranges where second voice coil is offset from gap are included in displacement ranges where A1 is set to A1st.

A case has a flat region and a tapered region on the periphery of the flat region. The centroid of the flat region is set at a position closer to a duct than the center line of vibration of the diaphragm is.

As a result, the back space in the case gradually widens from the position apart from the duct toward the duct along the circumferential loci.
