Abstract: A speaker system includes a speaker cabinet that has an opening, a first speaker including a first diaphragm, and at least one acoustic tube opened at both ends. When an amplitude of vibration of the first diaphragm vibrated by applying a correction AC signal together with the first AC signal to the first speaker is equalized to the amplitude of vibration of the second diaphragm, a sound pressure reproduced by vibration of the first diaphragm is equal to or lower than a sound pressure reproduced by vibration of the second diaphragm of the second speaker. This is accomplished by applying a third AC signal having a frequency equal to or higher than a minimum resonance frequency of the closed type cabinet determined by the internal volume of the closed type cabinet and the caliber of the second speaker is applied to the second speaker.

Abstract: A loudspeaker includes: a frame; a yoke fixed to the frame; a magnet fixed to the yoke; a plate fixed to an upper surface of the magnet which is opposite to a surface of the magnet which is fixed to the yoke; a vibratable voice coil arranged in a first magnetic gap formed between the yoke and the plate; a diaphragm having an outer-edge portion joined to the voice coil; and a support member supporting the diaphragm in a vibratable manner, and composed of edges, one end of each edge being fixed to the frame. The plate is composed of: a flat-plate part fixed to the upper surface of the magnet, and having, at an upper surface thereof, a planar portion extending from the outer-edge portion up to a predetermined distance; and a protruding part disposed on the flat-plate part excluding the planar portion, and protruding toward the diaphragm.
