Abstract
A duct that includes a pair of rib walls which are formed unitarily with a rear cabinet in such a manner that the rib walls face with other in the up and down direction. The duct serves as an air flow passage that extends from a rear-open portion of a speaker box and through which air flow produced by vibration of a speaker body passes. A heat radiating portion of a heat sink is disposed in the duct.
