Speaker apparatus and speaker box

摘要

A speaker apparatus comprises a speaker box SB in which a speaker 51(or 52) is placed, as well as a bass reflex port 22 (or 23), an electric circuit device 40 and a drip-proof wall 16 placed in the speaker box SB. One end of the bass reflex port 22 is open outside the speaker box SB while other end of the bass reflex port 22 is open in the speaker box SB. The drip-proof wall 16 isolates the electric circuit device 40 from the other end of the bass reflex port 22 so that the speaker apparatus can prevent water droplets intruding into the speaker box SB through the bass reflex ports 22 from reaching the electric circuit device 40.
