Description of the Invention: [Technical Field of the Invention] The present invention relates to an earpiece structure of an electronic device, particularly to an earpiece structure of a mobile phone. [Prior Art] With the development of the wireless communication industry, various design styles of money devices such as mobile phones are emerging one after another. In order to make their own electronic products go to the market, the performance of the electronic devices is improved. To attract consumers' attention. In the process of improving the electronic device, multiple components can be redesigned in structure or layout. For example, improvements to the keyboard, display screen, earpiece and microphone, each small improvement may bring meaning to the electronic device. Unexpected effects make it quickly sell well. The structure of the electronic device is generally designed to be above the display of the electronic device. By placing a sound hole in the electronic device, a speaker is arranged inside the electronic device. The sounding surface of the speaker is aligned with the sound. The hole, when the speaker is pronounced, its sound is transmitted from the sound hole. S, the electronic device is not designed to take into account the appearance of the structure of the earpiece. The political hole of the listening structure is too dim due to the accumulation of dust, which affects the appearance of the entire electronic device, so that it cannot attract the attention of consumers. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an earpiece structure of an electronic device which is simple in structure and can enhance the redundancy of the sound hole. An earpiece structure of an electronic device, comprising a casing, a speaker and a LED 201027964 lamp (Light Emitting Diode), wherein a cavity is formed on the casing and a sound is transmitted through the cavity The speaker is mounted in the cavity and is audible to the outside through the sound hole. The LED lamp is mounted on one side of the speaker, and the light of the LED lamp is emitted from the sound hole. Compared with the prior art, the earpiece structure of the electronic device is designed with an LED lamp on one side of the speaker, and the light of the LED lamp is scattered from the sound hole, which can enhance the brightness of the sound hole of the electronic device. The surface of the body is bright. [Implementation] Referring to FIG. 1, an earpiece structure 1 of an electronic device according to a preferred embodiment of the present invention includes a casing 10, a dustproof net 20, a speaker 30, a lens 40, an LED lamp 50, and a Circuit board 60. The air filter 20, the speaker 30 and a lens 40 can be mounted between the housing 10 and the circuit board 60. The LED lamp 50 is mounted on the lens 40 and located on one side of the speaker 30. One end of the housing 10 is formed with a cavity 12 and a sound hole 14 formed at the bottom of the cavity 12. The cavity 12 has a substantially rectangular groove structure for accommodating the dustproof net, the speaker 30, and the lens 40. The cavity 12 includes a first accommodating area 122 and a second accommodating area 124. The first accommodating area 122 is configured to receive the speaker 3A, and includes a peripheral wall 1222 surrounding the first accommodating area 122. The peripheral wall 1222 is surrounded by a shape and formed toward the second accommodating area. The opening 124 is formed in the area 124. The second receiving area 124 is for receiving the lens 40, and a plurality of fixing posts 1242 are protruded thereon for fixing with the lens 40. The cavity 12 is fixed. A recess 126 is defined in the bottom surface of the recess 126. The recess 126 is formed in the first accommodating area 122 and extends to one end of the second accommodating area 124. The recess 126 The sound hole 14 is opened at the bottom. The sound hole 14 also extends from the first accommodating area 122 to the second accommodating area 124. The sound hole 14 201027964 is used to match the speaker 30, so as to facilitate The sound of the speaker 3 is distributed. The size of the air filter 20 is equivalent to the size of the recess 126 of the housing 10 for mounting in the recess 126 to prevent dusting of the sound hole 14. The speaker 30 is configured to be received in the first accommodating area 122. The speaker 3 includes a broadcast surface (not shown) and two electrical connection terminals 32. The sound of the speaker 30 is transmitted through the sound emitting surface, and the two electrical connection terminals 32 are disposed on the end surface opposite to the sound emitting surface for connecting with the circuit of the electronic device. For example, PC, PMMA) is injection molded. The lens 40 is substantially a flat plate structure, and includes a plate portion 42 and a retaining wall 44 vertically formed at the end of the plate portion 42. The plate portion 42 is for receiving in the cavity. The second accommodating area 124 of the second portion 12 defines a square tube 422 and a plurality of fixing holes 424. The square tube 422 is adjacent to one side of the blocking wall 44 for mounting the led lamp 50. The fixing hole 424 is configured to sleeve the fixing post 1242 of the second receiving area 124 to fix the lens 40 to the second receiving area 124 of the housing 1 . The opening 1224 formed in the peripheral wall 1222 of the first accommodating area 122 is provided to have a better sealing effect when the speaker 30 is mounted in the first accommodating area 122, so that the electronic device obtains better sound quality. The LED lamp 50 is mounted in a square cylinder 422 of the lens 40, and the light emitted by the LED lamp 50 The wire can be dissipated from the sound hole 14 of the housing 1 . The circuit board 60 includes a protruding end 62 for pressing against the peripheral wall 1222 of the first receiving area 122 and The wall 44 of the lens 40 can enclose the speaker 30 in the first receiving area 122 of the housing 1 , so that the sound emitted by the speaker 30 can only be emitted from the sound hole 14 In this way, the sound quality of the speaker 3 can be improved. Referring to FIG. 2 and FIG. 3, when assembling the earpiece structure 1 of the electronic device, the dust-proof net 20 of the 201027964 is first placed into the groove 126 of the cavity. Then, the speaker 3 is assembled into the first accommodating area 122 of the cavity 12, and the sounding surface of the speaker 30 faces the sound hole 14; then the LED lamp 50 is assembled to the square tube 422 of the lens 4 Then, the lens 40 is assembled into the second accommodating area 124 of the cavity 12, and the plate portion 42 of the lens 40 and the bottom surface of the second accommodating area 124 are attached to the corresponding holes of the fixing hole 424 of the lens 4 The fixing post 1242 ′ of the second accommodating area 124 is disposed, and the fixing post 1242 can be integrated with the fixing hole 424 by a hot melt method to stabilize the lens 4 . Fixed to the housing 1〇, the lens φ wall 44 of the lens 4 is sealed against the opening 1224; finally, the circuit board 60 is assembled, and the circuit board 60 is fixed to the housing 10 by thread and stud In the manner of the fastening, the protruding end 62 of the circuit board 6 is pressed against the peripheral wall 1222 of the first accommodating area 122 and the blocking wall 44 ′ of the lens 40 to thereby close the speaker 30 to the shell. The first receiving area 122 of the body. When the electronic device is used, the sound hole 14 of the earpiece structure not only spreads the sound of the speaker 3 'while ' the light of the LED lamp 50 is dissipated from the sound hole 14 , and the structure of the earpiece 1 is bright 'making the electronic device The surface of the casing 10 is brightly colored. It can be understood that the lens 40 can be omitted by enclosing the peripheral wall 1222 of the first accommodating area 122 Q into a ring-shaped section, and the speaker 3 ( ) and the LED lamp 50 are disposed in the section. Inside.
