The single connection portion 4 includes: the loudspeaker comprises a fixing part 41 and a connecting part 42, wherein one end of the fixing part 41 is fixed on the outer wall of the shell 2, the connecting part 4 is used as a fixed connecting part of the whole loudspeaker, the fixing part 41 is fixedly arranged on the shell 2, and the fixing part 41 is connected and fixed, so that the whole loudspeaker can be positioned. The front end of the connecting piece 42 is hollow, the connecting piece 42 is detachably sleeved on the outer wall of the fixing piece 41, and the rear part of the connecting piece 42 is connected with a power supply. The connection portion 4 should therefore be able to electrically connect the relevant components inside the housing to the power supply, in addition to being able to function as a connection. To this effect, the fixing member 41 is electrically connected to the magnetic coil 1, and the connecting member 42 is electrically connected to a main power supply; after the connecting piece 42 is sleeved on the fixing piece 41, the magnetic coil 1 can be electrically connected with a main power supply by rotating the connecting piece 42.
