The invention discloses a magnesium alloy micro-arc oxidation horn for new energy automobile sound equipment, which comprises a horn main body, the surface of the horn main body is provided with a front shell and a rear shell, one side of the interior of the horn main body is provided with an echo plate and a castanet, and the center of the interior of the horn main body is fixedly provided with a movable iron core and a positive and negative motor. And a heat conduction frame and a silent fan are fixedly mounted on the other side in the loudspeaker main body. The magnesium alloy micro-arc oxidation loudspeaker for the new energy automobile audio facilitates regular wind direction adjustment and circulating heat dissipation, meanwhile, through cooperation of self-vibration of the loudspeaker and different wind directions, dust on the surface of the device is automatically removed, dust attachment is reduced, the service life of the device is prolonged, the sound quality of the loudspeaker is improved, and heat in the device is further concentrated through cooperation with a heat conduction frame. And the anti-collision outer layer and the ferrule are arranged to assist in guaranteeing the installation of the loudspeaker main body, so that the loudspeaker is simple and reasonable in structure and convenient to use, effectively solves most existing problems, and has relatively high practical value.
