Abstract: A live flaw detection system for a multi-bundled conductor splicing sleeve and an application method thereof are disclosed. The system includes an upper apparatus and a lower apparatus, where the upper apparatus includes an unmanned aerial vehicle and an industrial X-ray machine, and a laser sensor, and the lower apparatus includes a press plate frame apparatus, vertical screw slide table modules, a horizontal screw slide table module, a projection imager, and a linear retractable apparatus. The unmanned aerial vehicle functions as a power apparatus that controls the system to be online or offline, the industrial X-ray machine is configured to perform ray flaw detection on each splicing sleeve, the laser sensor is configured to guide the unmanned aerial vehicle to land the lower apparatus on splicing sleeves accurately, and the press plate frame apparatus is configured to fixedly clamp the splicing sleeves.

Abstract: The present invention discloses a speaker device. The speaker device comprises a speaker box, a heat source, and a heat conducting member; the speaker box comprises a housing, a speaker, a sound-guiding channel, and a heat conducting plate; the speaker includes a diaphragm, the first receiving space is divided into a front sounding chamber and a back chamber, and the sound-guiding channel communicates the front sounding chamber with the outside and forms a front chamber together with the front sounding chamber; the housing having an opening penetrating therethrough, the opening communicates with the front chamber, and the heat conducting plate covers on the opening, an adjusting hole penetrates through the housing and communicates with the back chamber; an valve covers on the adjusting hole and a controller for outputting a control signal to control the valve to open or to close.
