PROBLEM TO BE SOLVED: To provide a speaker device capable of efficiently reproducing low-pitched sounds.SOLUTION: As a cabinet 110 to which a speaker unit 120 is mounted, a sealed space CP1 to which sonic waves outputted from the back of the speaker unit 120 are conducted, a sound conduction space CP2 partitioned from the sealed space, and an exit 113 of sonic waves conducted in the sound conduction space are included. A diaphragm 131 is then disposed between the sealed space and the sound conduction space of the cabinet 110, and an actuator 140 is mounted to the diaphragm 131. A common audio signal with the speaker unit 120 is supplied to the actuator 140, and vibration of the diaphragm 131 is enhanced by the actuator 140. |
