Abstract

PROBLEM TO BE SOLVED: To fit a speaker without using a tool by providing a cabinet with an engagement part to engage a supporting face in front of a speaker and a first end part of the speaker and using a holding member which is engaged with the engaged parts of the cabinet and gives force for pressing the second end part of the speaker on the supporting face. SOLUTION: A sound conductor rib 7 for supporting the front of a speaker 4 and executing positioning is provided on a sideboard 3 of a cabinet 1. The upper end 4c of the speaker 4 is restrained to the lower end of a positioning rib 9 and right/left ends 4b and 4d are positioned by positioning ribs 8 and 9. Opening holes 11 and 12 are provided on the baseplate of the cabinet 1. The opening holes 11 and 12 have insertion parts 11a and 12a of sizes into which restraining pieces can be inserted and the narrow engagement parts 11b and 12b which are connected to the insertion parts and to which the restraining pieces can be engaged. The restraining piece 13 is inserted and it is laterally shifted. Thus, the pawl part of the restraining piece 13 gives force for depressing the lower end of the speaker 4 toward the beseplate 2.
