[0025] see figure 1 , the computer device 100 includes a casing 10, a circuit board 20 accommodated in the casing 10, and a vibration element disposed on the inner sidewall of the casing 10. In this embodiment, the vibration element is a vibration motor 30 .
[0026] The casing 10 is in the shape of a hollow cuboid, and includes a rectangular first panel 12 and a side panel 14 extending vertically from the periphery of the first panel 12 . The casing 10 further includes a second panel disposed opposite the first panel 12 and covering the end of the side panel 14 . In order to clearly show the internal structure of the casing 10, the second panel is omitted in the figure.
[0027] The side plate 14 is provided with an air inlet and an air outlet 18 . The air outlet 18 penetrates through the side plate 14 so that the internal system of the casing 10 is communicated with the external environment. A fan 19 is disposed at the air outlet 18 for extracting the air in the casing 10 to the outside.
[0028] The air inlet includes several small through holes 17 formed on the side plate 14 . The through holes 17 penetrate through the side plate 14 so as to communicate the internal system of the casing 10 with the external environment. The vibration motor 30 is arranged on the inner side of the side plate 14 and is close to the air inlet. The vibration motor 30 extends outward from one side to form two hooks 32 . Each hook 32 extends in an “L” shape along a direction parallel to the first panel 12 , and ends of the two hooks 32 are bent and extended toward each other. The two hooks 32 correspond to the two through holes 17 of the air inlet respectively. One side of the vibration motor 32 with the hooks 32 is attached to the inner surface of the side plate 14 . The hooks 32 extend from the outer surface of the vibration motor 30 toward the through hole 17 , respectively pass through the through hole 17 and hook on the side plate 14 . The side plate 14 is on the outer surface corresponding to the periphery of the through hole 17 , so that the vibration motor 30 is fixed on the side plate 14 . The clasp 32 is made of a material with good elasticity. In this embodiment, the clasp 32 is made of a metal material.
[0029] The circuit board 20 is flatly attached to the inner surface of the first panel 12 . The circuit board 20 is provided with a central processing unit 40 and a control device 50 for controlling the vibration motor 30 . The control device 50 is a programmable chip set, which controls the operation of the vibration motor 30 by setting a program inside. The control device 50 can be set to control the vibration motor 30 to start up during the shutdown process of the computer device 100, and can also be set to control the vibration motor 30 to start up when the computer device 100 is shut down, and the vibration motor 30 can drive the casing 10 when it works. The side plate 14 vibrates to shake off the dust accumulated in the through hole 17 of the air inlet. At the same time, the vibration motor 30 can be prevented from generating noise during the user's use of the computer device 100 and affecting the user's work. In addition, the length of the operation time of the vibration motor 30 can also be set by programming in the control device 50 .
[0030] figure 2 Shown is a functional block diagram of one of the control methods for the control device 50 to control the operation of the vibration motor 30 . The control device 50 includes a signal transmission unit 52 , a power terminal 53 , a switch unit 54 and a timing unit 56 . The switch unit 54 is connected to the power terminal 53 and the vibration motor 30 , and is used to control the vibration motor 30 to obtain power from the power terminal 53 to start or to stop working when the power is cut off from the power terminal 53 . The signal transmission unit 52 is connected between the central processing unit 40 and the switch unit 54, and is used for receiving a control signal sent by the central processing unit 40 and transmitting a driving signal to the switch unit 54, so as to control the opening or closing of the switch unit 54. closure. When the control program of the vibration motor 30 is set to be activated during the shutdown process of the computer device 100, when the computer device 100 is shut down and exits the system, the central processing unit 40 outputs a control signal to the signal transmission unit 52, the signal transmission The unit 52 receives the control signal and sends a drive signal to the switch unit 54. The switch unit 54 is turned on after receiving the drive signal, so that the power terminal 53 can supply current to the vibration motor 53 to drive the vibration motor 30 to start. The timing unit 56 is connected to the switch unit 54 . When the switch unit 54 drives the vibration motor 30 to start, the timing unit 56 starts timing, and when the working time of the vibration motor 30 reaches a preset value (eg, 5 seconds), the timing unit 56 sends a stop signal to The switch unit 54 is controlled to turn off the switch unit 54 , the electrical connection between the power supply terminal 53 and the vibration motor 30 is disconnected, and the vibration motor 30 stops working.
[0031] Similarly, when the control program of the vibration motor 30 is set to start when the computer device 100 is shut down, the central processing unit 40 sends a control signal to the signal transmission unit 52 when the computer device 100 is shut down. 52 sends a drive signal to the switch unit 54 after receiving the control signal, the switch unit 54 starts the vibration motor 30 after receiving the drive signal, and the timing unit 56 starts timing, when the working time of the vibration motor 30 reaches a preset value Afterwards, the switch unit 56 sends a stop signal to the switch unit 54 , and the switch unit 54 controls the vibration motor 30 to stop working.
