A speaker is provided to improve a coupling force between a speaker housing and a supporting housing by enlarging a coupling area of the speaker housing and the supporting housing. In a speaker, a vocal unit is installed on one side of a speaker housing(20). The vocal unit transforms an electrical signal to a sound. A supporting housing(30) is coupled to the speaker housing(20) to support the speaker housing(20). A coupling through hole(22) and a coupling column(32) are formed on corresponding positions of the speaker housing(20) and the supporting housing(30) so that the coupling column(32) is inserted into the coupling through hole(22). A coupling channel(34) and a coupling pin(24) are formed on corresponding positions of the coupling through hole(22) and the coupling column(32). The coupling channel(34) and the coupling pin(24) couple the speaker housing(20) and the supporting housing(30). |
