However, in the conventional speaker fixing structure, the height of the horizontal portion 2b of the stopper 2 from the upper surface of the cabinet 1 is limited, and thus the height of the edge of the speaker 3 varies. When the edge is higher than the height of the stopper 2, the speaker 3 is firmly inserted. When the edge is lower, a gap is formed between the edge of the speaker 3 and the horizontal piece 2a of the stopper 2. As a result, the speaker 3 cannot be fixed.

Another conventional speaker fixing structure is disclosed in Japanese Utility Model Laid-Open No. 4-72794. As shown in FIGS. 5 and 6, this conventional speaker fixing structure is different from the speaker fixing structure in which the speaker 11 is mounted in the case 14 immediately. A cushion 15 is provided on the speaker mounting surface of the case 14 and a guide 15 that fits with the mounting fixture 16 fixed to the speaker 11 and the outer periphery of the flange 11 a of the speaker 11. 3 sandwiches the flange portion 11a of the speaker 11.

However, in the conventional speaker fixing structure, a plurality of claws 12 are used to fix the flange portion 11 a of the speaker 11. Therefore, when the speaker 11 is mounted, the plurality of claws 12 are pushed and further pressed. The speaker 11 is difficult to be attached because it is mounted over the claw 12 so that the speaker 11 is difficult to be removed. Further, when removing the speaker 11, the speaker 11 must be opened and the speaker 11 must be removed. there were. In addition, since the flange 11a of the speaker 11 must be placed on the upper surface of the cushion 13 having elasticity, there has been a problem that the positioning accuracy must be increased.
