PROBLEM TO BE SOLVED: To solve the problem that it is desired to mount a passive radiator type speaker for reproducing bass because bass cannot be reproduced only by mounting one speaker in an acoustic space, however the passive radiator type speaker is expensive since only a driver consisting of a moving coil and a magnet is not attached and the other structure is the same as that of a waterproof speaker, thereby a bathroom television becomes considerably expensive.SOLUTION: Right and left acoustic spaces are air-tightly isolated with respect to a main space, openings which are open forwards are formed in both the acoustic spaces, and both the acoustic spaces are made into bass reflex speaker box. Speaker cords connected to an audio signal output section is drawn out through a wiring opening formed on a back of the main space, and the speaker cord is connected through either of the openings formed on backs of both the right and left acoustic spaces to a waterproof speaker. |
