[0008] [0007] 099132541 The button passes through the through hole and is partially exposed to the housing of the electronic device. The first sealing layer seals the outer casing and the button cap, and the second sealing layer seals the button cap and The PCB board is sealed, and the adhesive film is adhered to the switch, so that the first sealing layer, the second sealing layer and the adhesive film form a closed structure. With the button and electronic device of the present invention, the first sealing layer, the second sealing layer and the adhesive film prevent water and dust from entering through the perforations, thereby being waterproof and dustproof. [Embodiment] Referring to FIG. 1 to FIG. 2, the electronic device 100 includes a housing 1 , a pCB board 20 and a button 30 . In this embodiment, the electronic device is an MP3. The housing 1 includes a side wall 11 that includes a through hole 111. The PCB board 20 is fixedly mounted in the housing 1 , and the button 3 is disposed on the side wall 11 corresponding to the hole 111 and partially exposed to the housing 10 ′ for user operation. The PCB board 20 includes a pad (pAD) 2i including an outer ring pad 211 and an inner ring pad 212, when the outer ring pad 211 and the inner ring pad 212 conduct the second sealing layer 0992056980-0 'The PCB board 20 generates a button trigger signal. The button 30 includes a button cap 31 and a first sealing layer 32. Form No. A0101 Page 6 of 16 [0009] 201214479 33, an adhesive film 34 and a switch 35. The button cap 31 includes a button 36 and a resilient piece 37, and the button 36 is fixedly mounted on the elastic piece 37. In the present embodiment, the button 36 is circular. The button 36 is exposed through the perforation 112 to the housing 10 for user operation. The spring piece 37 provides a restoring force to the button 36 when the button 36 stops acting. [0010] In the embodiment, the elastic piece 37 includes a body 371, a connecting member 372, and a button piece 373. The body 371 includes a through hole 374. The connecting piece 372 and the button piece 373 are disposed in the through hole 374. The connecting piece 372 is fixedly connected to the body 371. The button piece 373 is fixedly connected to the connecting piece 372. The through hole 374 It is generally circular and has a radius greater than the radius of the button 36. The button 36 is fixedly coupled to the button 373. In other embodiments, the button 373 and the button 36 can be integrally connected. The connector 372 is made of an elastic material. When the button 36 is applied by an external force, the button 36 presses the button piece 373, and the connecting member 372 is deformed. When the external force is removed, the connecting member 372 provides an elastic force to the button piece 373, and the button 36 and the button piece are provided. 373 moves to the position where it is not pressed [0011]. In other embodiments, the sheet 37 is a resilient body that is fixedly mounted to the spring 37. The first sealing layer 32 and the second sealing layer 33 have the same structure and material, and only the first sealing layer 32 will be described below. The first sealing layer _ a waterproof double-sided tape. Both sides of the first sealing layer 32 are coated with a knee water substance. The first sealing layer 32 includes a perforation 321 . In the present embodiment, the size of the through hole 321 is larger than the size of the button 36. One side of the first sealing layer is adhered to the side wall, and the through hole 321 is passed through, and the other surface of the first sealing layer 32 is bonded to the elastic piece 37. One side of the second seal (10) is pasted. 099132541 Form No. A0101 Page 7 of 16 0992056980-0 201214479 On the elastic piece 37, the other side of the second sealing layer 33 is adhered to the adhesive film 34. [0012] In the present embodiment, the adhesive film 34 is a high temperature resistant polyester film (PET film), and has a waterproof and dustproof effect. The adhesive film 34 adheres the switch 35 to the PCB 20, and the size of the adhesive film 34 is the same as that of the first sealing layer 32 and the second sealing layer 33. Therefore, the first sealing layer 32, the second sealing layer 33 and the adhesive film 34 form a closed structure, and the through holes 11 2 of the side wall 11 are separated from the PCB board 20, thereby preventing water and dust from entering through the perforations. PCB board 20. [0013] In the embodiment, the switch 35 is a metal dome, and the switch 35 has a pot-shaped structure that is inverted, and the switch 35 can automatically return to the position after being pressed. The switch 35 includes an outer ring 351 and an inner ring 352. The outer ring 351 of the switch 35 is electrically connected to the outer ring pad 211 of the PCB 20 under the fixing action of the adhesive film 34. The inner ring 352 of the switch 35 is movably and electrically connected to the inner ring pad 212 of the PCB 20. . When the switch 35 is in the initial state, the inner ring 352 of the switch 35 is distant from the inner ring pad 212 of the PCB board 20. When the switch 35 is pressed, the inner ring 352 of the switch 35 is electrically connected to the inner ring pad 212 of the PCB board 20, so that the outer ring pad 211 and the inner ring pad 212 of the PCB board 20 pass through the switch 35. Turning on, the PCB board 20 generates the button trigger signal. Referring to FIG. 3, when the assembly is assembled, the switch 35 is placed at a position corresponding to the corresponding pad 21 of the PCB board 20. The adhesive film 34 fixes the switch 35 to the PCB board 20. The first sealing layer 32 is adhered to the casing 10 and the other surface is adhered to the button cap 31. The button 36 is exposed through the through hole 321 of the first sealing layer 32 and the through hole 112 of the casing 10 to be exposed. The housing 10 099132541 Form No. A01O1 Page 8 / Total 16 pages 0992056980-0 201214479 For the user, the second sealing layer 33 is adhered to the button cap 31 and the other surface is adhered to the adhesive film 34. Therefore, as described above, the first sealing layer 32, the second sealing layer 33, and the adhesive film 34 form a closed structure, and the perforations 112 of the casing 10 are closed to isolate the perforations 112 from the PCB board. It is impossible to enter the PCB through the through hole 112 of the casing 10, thereby achieving the waterproof and dustproof effect. [0015] In use, the button 36 is pressed, and the button 36 presses the button 373 to overcome the elastic force of the connector 372, so that the button 36 is pressed against the switch v 35, the inner ring 352 of the switch 35 and the PCB The inner ring pad 212 on the 20 is electrically connected, and the outer ring pad 211 on the PCB 20 and the inner ring pad 21 2 on the PCB 20 are electrically connected through the switch 35, so that the PCB generates a button. signal. When the external force is cancelled, the connecting member 372 provides a restoring force to the button piece 373, and the button piece 373 drives the button 36 to return to the initial position. Due to the disappearance of the resisting action of the button 36, the switch 35 is returned to the initial position, and the inner ring 352 of the switch 35 is away from the inner ring pad 212 on the PCB board 20 and the outer ring pad 211 and the PCB board on the PCB board 20. The inner ring j pad 212 on 20 is electrically disconnected, and the PCB stops generating the button signal. [0016] Those skilled in the art should understand that the above embodiments are only for illustrating the present invention, and are not intended to limit the present invention, as long as it is within the spirit of the present invention, the above embodiments. The appropriate changes and modifications are within the scope of the claimed invention.
