A computer
display device component capable of lowering
noise comprises a direction adjustable display panel (91) in a horizontal plane, the display panel (91) is rotatablely matched and connected with the bottom wall of a direction adjusting device housing (3) through a suspension shaft (931) fixedly connected to an upper part, a disk type gear (93) is fixedly arranged at the upper part, extending into the inner chamber of the direction adjusting device housing (3), of the suspension shaft (931) so as to be meshed with a
pinion (82) mounted on a transmission shaft (32) driven by a motor (31), a sound proof box (14) is arranged at the periphery of the motor and used for lowering
noise produced during the running of the motor (31), the sound proof box (14) is made of a
metal material and plays a temperature reducing effect, a gearwheel (821) is further mounted on the transmission shaft (32) and used for being meshed with a rack part (81) of a transmission sliding part (8) so as to drive the transmission sliding part (8) to move back and forth under the guiding of the inner wall of the direction adjusting device housing (3).
