DETAILED DESCRIPTION

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, so that the embodiments of the application described here, based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0023] Reference Figure 1-Figure 4 A portable loudspeaker includes a loudspeaker body 3, which includes a magnetic circuit system (permanent magnet, core column, magnetic conductive plate), a vibration system (paper cone, voice coil) and a supporting auxiliary system (centering support sheet, basin frame, pad edge). The audio AC signal through the coil interacts electromagnetically with the magnet to vibrate the surrounding air and make sound. The loudspeaker body 3 is an existing mature technology and is an application of the existing technology. No further details are given here. A loudspeaker cover 6 is provided on one side of the loudspeaker body 3. A fixing column 15 is welded to the top and bottom of the loudspeaker cover 6.
