Such conventional speaker fixing politics is applied to a part of the speaker 4 to fix the speaker 4 itself, thereby changing the sound quality of the speaker 4, and at first, there is no abnormality and time passes. As a result of the progressive deformation, there was a problem that the sound quality of the speaker (4) adversely affects. In addition, the Korean Utility Model Publication No. 89-15554 discloses an assembly groove on the inner wall of the panel (1) speaker seating groove (2). After forming the slide groove (4) connected to the (3) to be inclined at a predetermined angle, the fixing projection (7) protruding at the same slope as the slide groove (4) to the frame (6) of the normal speaker (5) assembly groove ( 3) The speaker fixing device of the electronic product of the electronic product which inserts in and rotates to the right and fixes the speaker is known. Such a speaker fixing device does not use fastening parts such as brackets and bolts. Since the picker is directly fixed to the panel, the assembly becomes simple, but in order to use the locking fastening structure of the speaker fixing device, a special type of speaker having a fixed protrusion formed on the frame is required, thus increasing the production cost. The speaker can not only be limited to the above uses, but a small speaker such as a mobile phone is difficult to form a separate shape on the speaker has a problem that is difficult to apply in practice. In addition, since the rigid metal speaker frame is fastened directly to the synthetic resin panel is a rigid body has no buffering force at all, there is a problem that the tightening is loosened by the vibration of the speaker after a long time, the sound quality is degraded.

The present invention has been made in order to solve the above problems and defects as described above, and assembling the speaker to the case of the mobile terminal easily, firmly, and not to deform so that the sound quality remains unchanged. An object of the present invention is to provide a speaker fixing device of a mobile terminal.
