A spring mounting seat of a speaker is characterized by comprising a spring piece and a spring seat, wherein the spring piece is shaped like a Chinese character 'zhi' and is riveted in a groove of the spring seat, thus not only meeting the requirement of reliable fixation, but also being convenient for drawing out the speaker during overhaul. The fixed tongue of the speaker is wedge-shaped, thus ensuring that the speaker is tighter when being inserted more deeply and is fixed reliably and solving the problem that small electric apparatuses are difficult to overhaul when being mounted in narrow space.
