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.

Abstract: A monitor having a rotable connection terminal. A monitor body to display an image is coupled to a supporting base with an adjustable link which permits the monitor body to be positioned at various angles relative to the base. The connection terminal is operatively to the monitor body and adapted to receive a second cable which provides an operational signal for the monitor body. The connection terminal is rotatably coupled to one of the base and the monitor body to permit the second cable to be connected to the connection terminal from various angles relative to the base, whereby the position of the second cable may be conveniently located for operation of the monitor according to a mounting orientation of the monitor base, contributing to an aesthetically pleasing appearance of the monitor.
