Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-2, the present invention provides a communication terminal 100, which includes a frame 1, a screen 2 and a rear cover 3 respectively covering opposite sides of the frame 1 and enclosing an accommodating space together with the frame 1, a speaker 4 accommodated in the accommodating space, a through hole 11 penetrating through the frame 1, and a dust screen having a plurality of micro holes and fixed to the frame 1 and completely covering the through hole 11.
The sound-producing side of the speaker 4 is arranged right opposite to the through hole 11, so that sound is produced through the through hole 11.
The dust screens include an inner dust screen 5 having a plurality of inner pores 51 and an outer dust screen 6 having a plurality of outer pores 61.
In the present embodiment, the inner dust screen 5 and the outer dust screen 6 have the same size, i.e., the same shape and area. The number of the outer micro holes 61 is twice the number of the inner micro holes 51, and the pore diameter of the inner micro holes 51 is larger than that of the outer micro holes 61. In this embodiment, the inner dust-proof net and the outer dust-proof net are both made of hard materials, such as stainless steel.
The inner dustproof net 5 is covered on the through hole 11, and the periphery of the inner dustproof net is embedded and fixed in the frame 1. The frame 1 further comprises an accommodating groove 12 formed by recessing the outer side of the frame, the through hole 11 is located in the accommodating groove 12, and the outer side of the inner dust screen 5 is exposed to the accommodating groove 12.
The communication terminal 100 further comprises a gland 7 matched with the accommodating groove 12 in shape, the gland 7 is provided with a sound hole 71 opposite to the through hole 11, the periphery of the gland 7 protrudes to form a clamping wall 72, and the clamping wall 72 surrounds the sound hole 71.
The outer dust screen 6 abuts against the gland 7 and has its periphery clamped to the clamping wall 72 to form a detachable connection. For example, the pressing cover 7 is made of plastic material, that is, the clamping wall 72 has certain elasticity, and the outer dust screen 6 can be pressed and clamped on the clamping wall 72 to form a detachable connection.
The gland 7 is covered in the containing groove 12 to form detachable connection, the outer dust-proof net 6 and the inner dust-proof net 5 are completely overlapped and abutted with each other, each inner micropore 51 and two adjacent outer micropores 61 are oppositely configured, part of each two adjacent outer micropores 61 is positioned in the range of the inner micropore 51 which is oppositely configured, and part of each two adjacent outer micropores 61 is positioned outside the range of the inner micropore 51 which is oppositely configured. This structure makes the dust form a monolithic structure when outer micropore 61 department deposit is full, and only can extend the partial area of deposit in the interior micropore 51 that corresponds, and can not block up interior micropore 51 completely, has effectively improved dustproof effect, when pulling down the gland this moment, the dust that outer micropore 61 was blocked up in the deposit is because of being a whole, then demolishs along with outer dust screen 6 and is taken out through-hole 11, and will extend to the part dust in interior micropore 51 is whole to be taken out, need not to wash interior dust screen 5, and outer dust screen 6 can be dismantled and wash and recycle, has effectively reduced use cost
In this embodiment, the thickness of the gland 7 is smaller than that of the outer dust screen 6, so that the depth of the sound hole 71 is small, dust is less prone to depositing in the sound hole 71, the depositing speed of the dust on the outer dust screen 6 is slowed down, and the times of disassembly and cleaning are reduced.
Compared with the prior art, the communication terminal is provided with the inner dust screen and the outer dust screen at the through hole of the frame, the inner dust screen and the outer dust screen are the same in size, the number of the outer micropores is twice of that of the inner micropores, the aperture of the inner micropores is larger than that of the outer micropores, the inner dust screen is covered on the through hole, the periphery of the inner dust screen is embedded and fixed in the frame, the outer dust screen abuts against the gland and is clamped on the clamping wall to form detachable connection, the gland is covered in the accommodating groove to form detachable connection, the dustproof effect of the double dust screens is realized, the outer dust screen forms dustproof protection on the inner dust screen and can be easily and simply detached, the communication terminal can be cleaned and reused, and the problem of increased use cost caused by frame replacement is solved; moreover, when the outer dust-proof net and the inner dust-proof net are completely overlapped and mutually abutted, each inner micropore is oppositely configured with two adjacent outer micropores, the adjacent two outer micropores are partially positioned in the range of the inner micropores which are oppositely configured, and all have parts located outside the range of the inner micropores which are arranged opposite to the outer micropores, the structure ensures that dust forms a whole when the outer micropores are fully deposited, and only can extend the partial area deposited at the corresponding inner micropores, but can not completely block the inner micropores, thereby effectively improving the dustproof effect, when the gland is dismounted, the dust deposited and blocking the outer micropores is integrated, the dust-proof net is taken out of the through hole along with the disassembly of the outer dust-proof net, and part of dust extending into the inner micro hole is taken out integrally without cleaning the inner dust-proof net, and the outer dust-proof net can be disassembled, cleaned and recycled, so that the use cost is effectively reduced.
While the foregoing is directed to embodiments of the present invention, it will be understood by those skilled in the art that various changes may be made without departing from the spirit and scope of the invention.
