[0041] In the embodiment, a bass loudspeaker is provided, which comprises a spider 1, a cone 2, a voice coil 3, an aluminum support 4, a positioning branch 5, a T iron 6, a magnet 7, an upper clamping plate 8, a breathable mesh 9, a connecting sheet 10, a lead wire 11, a wiring assembly 12, a connecting piece 13, a protective sleeve 14, a nameplate 15 and a fixing bolt 16.

[0042] In the embodiment, the spider 1 is an integrated cast aluminum spider, which significantly improves the heat dissipation performance of the loudspeaker, effectively solves the problem of poor heat dissipation of the traditional plastic spider, and thus ensures the long-term stable use and high-quality audio output of the loudspeaker. At the same time, the integrated cast aluminum spider also enhances the structural stability of the loudspeaker, so that it can withstand greater vibration load without being easily deformed.

[0043] In the embodiment, the cone 2 is arranged on the spider 1 and is an integrated aluminum cone. The integrated cone 2 not only reduces the weight, but also further improves the audio response and durability, so that the loudspeaker plays low-pitched sounds more powerful and powerful.

[0044] In the embodiment, the T iron 6 is arranged at the inner bottom of the spider 1, and the magnet 7 and the upper clamping plate 8 are sequentially sleeved on the T iron 6 from bottom to top; specifically, the T iron 6, the magnet 7 and the upper clamping plate 8 jointly constitute a magnetic circuit system of the loudspeaker, which provides the necessary magnetic field for the voice coil 3, so as to drive the cone 2 to vibrate and sound.
