Connect muscle 12422 and set on the cabling portion 12423 of one end away from board body part 12421 of dowel 12422, the first cabling channel 1244
In cabling portion 12423.First loudspeaker assembly 210 further include be set to the top of support plate 1242 and with the first loudspeaker 211
The loudspeaker mainboard 213 of electrical connection.The quantity in cabling portion 12423 is two, and two cabling portions 12423 are respectively arranged on support plate
1242 opposite two sides, so that the cable that one end and loudspeaker mainboard 213 are electrically connected can be from the two sides of support plate 1242
Cabling, cabling are simple and safe and reliable.First cabling channel 1244 is horizontally extending.The extending direction of second cabling channel 1222
It is vertical with the extending direction of the first cabling channel 1244.
Further, the inner wall of the second cabling channel 1222 includes circumferentially closed circumferentially closed hole wall 12221 and circumferential tool
There is a slotted wall 12222 of side notch, slotted wall 12222 is from one end close to top-support 124 of circumferentially closed hole wall 12221
Extend towards top-support 124, preferably to limit cable.Circumferentially closed hole wall 12221 is cylindrical surface, slotted wall
12222 be arc-shaped surface, and the radius of circumferentially closed hole wall 12221 is equal to the radius of slotted wall 12222.Slotted wall 12222 is in
Semicircle arc surface.Walking spool is hollow cylindrical tube.
The above embodiment is only the preferred embodiment of the present invention, and the scope of protection of the present invention is not limited thereto,
The variation and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed range.
