[0034] As Figure 1 and Figure 2 shown, the communication device includes a housing 10 and a display screen assembly 20 assembled to the housing 10. The housing 10 includes an annular outer peripheral wall 21, and a receiving space 50 is formed within the outer peripheral wall 21. The display screen assembly 20 is assembled to the housing 10 and at least partially received within the receiving space 50. The communication device is provided with a receiver hole 30, and the receiver hole 30 is located at the upper part of the housing 10. The communication device further includes a receiver assembly 40 disposed within the housing 10. When the user receives a communication requirement, the receiver assembly 40 is configured to convert an electrical signal into sound information recognizable by the human body. Among them, the receiver assembly 40 includes a receiver module 44, a bracket 42, and a dust-proof net 41 disposed on the bracket 42. The receiver module 44 is assembled to the bracket 42, and the bracket 42 is provided with a sound outlet hole 421 corresponding to the receiver hole 30. The dust-proof net 41 is disposed at the position of the sound outlet hole 421 and covers the sound outlet hole 421 to separate the sound outlet hole 421 from the receiver hole 30.

[0035] The user brings the receiver hole 30 close to the user's ear. The receiver module 44 converts the electrical signal into sound information recognizable by the user and outputs it. The sound information is transmitted to the user's ear through the sound outlet hole 421 and the receiver hole 30, enabling the user to receive the sound information. The receiver hole 30 is used to connect the sound outlet hole 421 and the external environment. The dust-proof net 41 is disposed therebetween at an interval, so that when external air and foreign matters such as dust enter the sound outlet hole 421, they are all filtered by the dust-proof net 41, thereby preventing foreign matters such as dust from blocking the sound outlet hole 421 and improving the call quality.

[0036] When the communication device is a mobile phone product with a smaller frame, such as a full-screen mobile phone, etc. The position from the earpiece hole 30 to the edge of the casing 10 is small. The sound outlet hole 421 is opened on the bracket 42, and the fixing of the dust-proof net 41 is realized through the mutual cooperation of the bracket 42 and the casing 10. By making full use of the large bonding area of the bracket 42, the dust-proof net 41 covers the sound outlet hole 421, and the covering effect is good, which can meet the setting of the earpiece hole 30 of the mobile phone product with a narrow frame, and the structure is beautiful. By setting the bracket 42, the position of the earpiece module 44 in the mobile phone can be adjusted, such as extending in the space between the display screen assembly 20 and the casing 10, improving the utilization rate of the internal space of the communication device and the reasonable layout to improve the call quality.

[0037] Such as Figure 2 And Figure 3 As shown, the outer peripheral wall 21 of the casing 10 surrounds the display screen assembly 20, and the outer peripheral wall 21 has a corresponding thickness or curvature to form a corresponding receiving space. The earpiece hole 30 is provided on the casing 10 or at the joint of the casing 10 and the display screen assembly 20. The closer the center of the sound outlet hole 421 on the bracket 42 is to the center of the earpiece hole 30, the better the sound transmission effect. The outer peripheral wall 21 of the casing 10 is used to accommodate at least part of the bracket 42 so that the earpiece hole 30 corresponds to the sound outlet hole 421. In one embodiment, the sound outlet hole 421 is at least one arranged in the horizontal direction of the communication device. For example, the sound outlet hole 421 is set to be two side by side, and a reinforcing rib is provided between the adjacent sound outlet holes 421.

[0038] In one embodiment, a groove portion 22 is formed on the outer peripheral wall 21 of the casing 10. The groove portion 22 is locally recessed from the inner surface of the outer peripheral wall 21. At least part of the bracket 42 is inserted into the groove portion 22, and a part of the dust-proof net 41 is located between the bracket 42 and the groove portion 22.

[0039] By providing the groove portion 22 on the outer peripheral wall 21 of the casing 10 to form a receiving space, one end of the bracket 42 having the sound outlet hole 421 is partially inserted into the groove portion 22, and the deviation between the center of the sound outlet hole 421 and the center of the earpiece hole 30 is reduced, improving the output quality of the sound. The dust-proof net 41 covers the sound outlet hole 421, extends along the surface of the bracket 42 and is fixed to the surface of the bracket 42. The groove portion 22 is used to accommodate part of the dust-proof net 41, which can reduce the deviation amount between the center of the sound outlet hole 421 and the center of the earpiece hole 30. Or the bracket 42 pushes the groove portion 22 against the groove portion 22, so that the dust-proof net 41 is subjected to a squeezing force, further improving the firmness of the dust-proof net 41 and making it not easy to fall off. The groove portion 22 is provided on the outer peripheral wall 21 of the casing 10, and the original solid part of the outer peripheral wall 21 is recessed to form a receiving space 50, reducing the frame width and improving the space utilization rate, and the structure is ingenious.

[0040] The groove portion 22 is used to accommodate a part of the bracket 42. At the same time, it also has the function of supporting the bracket 42 to stabilize its installation position. In an embodiment, the groove portion 22 includes a step surface 222 and an inner wall surface 221 extending in the direction of the earpiece hole 30. The step surface 222 extends in the direction of the center of the accommodation space 50 of the frame, and the inner wall surface 221 extends in the direction of the end of the outer peripheral wall 21. Among them, the inner wall surface 221 is set as an arc surface or an inclined surface. At least a part of the bracket 42 is erected on the step surface 222, and a part of the dustproof net 41 is located between the inner wall surface 221 and the bracket 42.

[0041] An included angle-like structure is formed between the step surface 222 and the inner wall surface 221. The bracket 42 is inserted into the groove portion 22 and erected on the step surface 222, so that the bottom of the bracket 42 fits the step surface 222. The end of the bracket 42 is covered with a dustproof net 41, and the dustproof net 41 and the inner wall surface 221 are in contact with each other or arranged at intervals. The step surface 222 is used to support the bracket 42, which is convenient for controlling the vertical distance between the sound outlet hole 421 on the bracket 42 and the earpiece hole 30. At the same time, the setting of the inner wall surface 221 can facilitate the adjustment of the lateral distance between the sound outlet hole 421 and the earpiece hole 30. The installation and adjustment of the bracket 42 are convenient, and the installation position is stable.

[0042] The earpiece hole 30 is used to output the sound output by the earpiece assembly 40, and it is directly communicated with the outside air. In an embodiment, the housing 10 is provided with a notch 23, and the position of the notch 23 corresponds to the groove portion 22. The notch 23 extends from the inner surface of the outer peripheral wall 21 of the housing 10 to the edge of the outer peripheral wall 21. The display screen assembly 20 is fixedly connected to the housing 10 and forms the earpiece hole 30 at the notch 23. The dustproof net abuts against the inner wall surface 221 of the groove portion 22 and is partially exposed to the earpiece hole 30, with beautiful appearance.

[0043] As Figure 3 and Figure 4 shown, the sound outlet hole 421 is located on the bracket 42 and penetrates the bracket 42. The bracket 42 further includes a first side wall 422 located at the position of the sound outlet hole 421 and a second side wall 423 that intersects the sound outlet hole 421 obliquely. The first side wall 422 and the second side wall 423 are arranged on opposite sides of the sound outlet hole 421. The bracket 42 further includes two third side walls 424 connecting the two ends of the first side wall 422 and the second side wall 423. Among them, the first side wall 422 is arranged on the side close to the display screen assembly 20, while the second side wall 423 is arranged on the side far from the display screen assembly 20.

[0044] A part of the dustproof net 41 is attached to the first side wall 422. Among them, the dustproof net 41 and the first side wall 422 are adhesively connected by an adhesive, and the two are tightly fixed. Another part of the dustproof net 41 extends in the direction of the sound outlet hole 421 and covers the sound outlet hole 421. Among them, the connection between the other part of the dustproof net 41 and the bracket 42 can include the following two forms:

[0045] a. Press-fit connection. A receiving cavity is formed between the second side wall 423 of the bracket 42 and the inner surface of the housing 10. Inside this receiving cavity, the bracket 42 is pressed tightly against the housing 10, such that the dust-proof net 41 is clamped by the inner surface of the housing 10 and the second side wall 423, and the dust-proof net 41 fits onto the second side wall 423. At the same time, the dust-proof net 41 extends out of the sound outlet hole 421 and extends to both sides and fits onto the third side wall 424, so that the sound outlet hole 421 is completely covered by the dust-proof net 41.

[0046] b. Fixed connection. A part of the dust-proof net 41 is adhesively connected to the first side wall 422, and another part covers the surface of the bracket 42 and extends to the second side wall 423. An adhesive is coated at a corresponding position on the second side wall 423 so that a part of the dust-proof net 41 fits onto the second side wall 423. Correspondingly, the dust-proof net 41 extends out of the sound outlet hole 421 and extends to both sides and fits onto the third side wall 424, so that the sound outlet hole 421 is completely covered by the dust-proof net 41.

[0047] The second side wall 423 is used to adjust the relative position between the center of the sound outlet hole 421 and the center of the earphone hole 30. Reducing the thickness of the second side wall 423 can correspondingly reduce the distance between the sound outlet hole 421 and the housing. In one embodiment, the bracket 42 includes a second side wall 423 that intersects the sound outlet hole 421 obliquely. The second side wall 423 intersects the sound outlet hole 421 obliquely. For example, the surface of the second side wall 423 is set as an arc surface, and the thickness of the second side wall 423 gradually increases from the sound outlet hole 421 to the other end of the second side wall 423. A groove portion 22 corresponding to the second side wall 423 is provided on the housing 10, and this groove portion 22 is used to accommodate the second side wall 423. By providing the second side wall 423 with a gradually changing thickness to adjust the position of the center of the sound outlet hole 421 relative to the housing 10, the adjustment is convenient, and it is ensured that there is sufficient force-bearing area between the dust-proof net 41 and the second side wall 423, and the connection is reliable.

[0048] The earphone assembly 40 includes an earphone module 44, and the bracket 42 is used to output the sound information emitted by the earphone module 44 from the sound outlet hole 421. The earphone module 44 is disposed inside the housing 10. In one embodiment, the earphone module 44 is located between the housing 10 and the bracket 42, and a sound outlet channel 43 is formed between the bracket 42 and the housing 10. The sound outlet hole 421 is the outlet of the sound outlet channel 43. The sound outlet channel 43 is used to connect the earphone hole 30 and the earphone module 44, such that the sound information emitted by the earphone module 44 is transmitted along the sound outlet channel 43 and output from the sound outlet hole 421 and the earphone hole 30, enabling the user to obtain this sound information. Among them, the bracket 42 and the housing 10 are connected by adhesive bonding or fastening connection, so that a sound outlet channel 43 is formed between the bracket 42 and the housing 10. By adjusting the structure of the bracket 42 to change the installation position of the earphone module 44, the internal space of the housing 10 is fully utilized, and the installation is convenient.
