Abstract

A speaker apparatus which does not need insertion of a stand into a speaker box, and which can prevent vibrations occurring in a speaker unit from transmitting to the speaker box by the speaker apparatus itself is provided. Within a speaker box which can be divided into first and second half portions, a plurality of supports extending from a main body portion of a weight radially are fixed at a connecting portion of the speaker box by bolts. A driving portion of a speaker unit is coupled to the main body portion of the weight, and is supported inside the speaker box in a manner that vibrations do not transmit, by the main body portion of the weight acting as a virtual ground. In order to swing the speaker box, a stand and the speaker box are pivotally supported by a pivotally supporting mechanism.
