ABSTRACT:
A speaker apparatus includes a speaker, and a circuit to operate the speaker. The speaker apparatus further includes a speaker box having an opening to enclose a back of the speaker; a casing accommodating the speaker box combined with the speaker and the circuit therein, and communicating with an outside so as to dissipate heat from the circuit; and a duct penetrating the casing and the speaker box so as to emit back sound of the speaker. The present invention provides a speaker apparatus, which has high heat-dissipating efficiency, can be manufactured in various designs, and prevents a user from being burned.
