The utility model provides an internal heat dissipation structure of a wall-mounted
sound box, which comprises a
sound box body, through the use of a heat dissipation mechanism, the dynamic movement of a heat dissipation
fan in a placement cavity is realized, after a motor is started, the rotation of a
threaded rod drives a moving block to move along the direction of the moving block, and the arrangement of balls converts sliding friction into rolling friction, so that the heat dissipation effect of the
sound box is improved. The transmission efficiency is remarkably improved, heat and
energy loss generated by mechanical friction is reduced, the moving block can more smoothly do
reciprocating motion, the service life of mechanical parts is prolonged, the cooling fan moves along with the moving block, uniform cooling is conducted on the interior of the containing cavity, and hot air in the containing cavity is cooled through the flow guide cover. The air is discharged through the corrugated
pipe and the
exhaust pipe, the corrugated
pipe has flexibility and can adapt to the position change of the cooling
fan in the moving process, meanwhile, smooth transmission of the air flow is kept,
excessive cooling holes do not need to be formed in the inner wall of the
loudspeaker box body, the working stability of electronic elements in the
loudspeaker box is improved, and the service life of the electronic elements in the
loudspeaker box is prolonged.
