Abstract
A speaker case includes a first part and a second part connected to the first part. Each of the first part and the second part has a recess defined in each sidewall thereof and the two recesses are cooperated to define a hole through the case. A connector includes a tubular body with grooves defined in the outer periphery thereof so that the sidewalls of the first part and the second part a first case are engaged with one groove, and the sidewalls of a second case are engaged with the other groove so that the two speaker cases are combined together. The connector may have a close end, an enlarged end or a threaded inside so as to have further functions.
