Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the word "over" a first feature or feature in a second feature may include the word "over" or "over" the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature "under" a second feature may include a first feature that is directly under and obliquely under the second feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

As shown in fig. 2, the earphone easy to assemble of this embodiment includes a casing 1, a sound generating unit 2, a first connecting line 3, a circuit board 4 and a sealing sheet 5, a through hole 11 has been opened on the casing 1, a microphone is provided on the circuit board 4, one end of the first connecting line 3 is connected with the sound generating unit 2, the other end of the first connecting line 3 is connected with the circuit board 4, the through hole 11 can be passed by the circuit board 4, the circuit board 4 and the sound generating unit 2 are respectively located at two sides of the through hole 11, and the sealing sheet 5 covers the through hole 11.

Fig. 1 shows is a structure of current earphone, through wires hole 12 has been seted up on its casing 1, first connecting wire 3 of being connected with sound generating unit 2 need pass through wires hole 12 after again with circuit board 4 welding, in order to reduce sealed degree of difficulty, through wires hole 12's size sets up less, it is difficult to accomplish sooner to cause the threading operation, and before first connecting wire 3 and circuit board 4 welded fastening, roll-off in through wires hole 12 is followed very easily to first connecting wire 3, lead to needing rethread, greatly reduced packaging efficiency.

With reference to fig. 3, the earphone easy to assemble in this embodiment is configured with the through hole 11 on the casing 1 for the circuit board 4 to pass through, so that the wires such as the first connecting wire 3 can be welded on the circuit board 4 in advance, and the conventional operation of welding after threading is not needed, thereby avoiding the phenomenon that the wires such as the first connecting wire 3 slide out from the threading hole 12 before welding and fixing, and greatly improving the assembling efficiency. The sealing sheet 5 is used to cover the through hole 11, so that the area required to be coated with glue for sealing is reduced, the sealing difficulty is reduced, and then the microphone on the circuit board 4 is effectively isolated from the sound generating unit 2 on the other side of the through hole 11, so that the sound waves generated by the sound generating unit 2 cannot directly influence the microphone, and the microphone is guaranteed not to be interfered when used.

Preferably, an adhesive layer is disposed on one surface of the sealing sheet 5, and the adhesive layer is connected to the housing 1 to fix the sealing sheet 5 to the housing 1. By arranging the adhesive layer, the sealing sheet 5 can be very conveniently fixed on the shell 1, and the through hole 11 is covered to reduce the area of the area needing adhesive sealing.

Preferably, the size of the sealing sheet 5 is larger than that of the through hole 11, so that only one sealing sheet 5 is needed to cover the through hole 11 in a large area, and the assembly efficiency is improved. The gasket 5 and the through hole 11 can both be set up to the rectangle, make things convenient for the location of gasket 5, reduce and paste the degree of difficulty.

Preferably, the first connecting line 3 abuts against the wall of the through hole 11 and the edge of the sealing sheet 5, so that the area of a gap generated between the sealing sheet 5 and the edge of the through hole 11 is minimized, and the area of an area to be sealed by glue is minimized.

In some embodiments, as shown in fig. 4, the edge of the sealing sheet 5 is provided with a plurality of first notches 51, and the first connecting lines 3 are embedded in the first notches 51, so that the first connecting lines 3 can be well fixed in the first notches 51, and the flat cables are more orderly. Because first connecting line 3 imbeds in first breach 51, the gasket 5 can cover the bigger area of through-hole 11, has further reduced the regional area that needs the rubber coating to seal, has reduced the sealed degree of difficulty of rubber coating, and because the reduction of rubber coating volume, has also reduced the cost of glue.

Further, the first notch 51 is U-shaped, so that the bottom of the first notch 51 can be attached to the first connecting line 3, and compared with the first notch 51 having other shapes, such as a rectangular shape, the gap is smaller, and therefore the glue sealing is easier to be achieved.

As shown in fig. 5, in some embodiments, the edge of the through hole 11 is provided with a plurality of second notches 111, the first notch 51 and the second notch 111 are both semicircular and can be spliced to form a circular hole, and the first connecting line 3 passes through the circular hole. The first notch 51 and the second notch 111 are arranged according to the diameter of the first connecting line 3, so that when the sealing sheet 5 is fixed on the housing 1, almost no gap is generated around the first connecting line 3, and a better sealing effect can be obtained after the adhesive is applied.

As shown in fig. 2 to 5, in some embodiments, a battery 6 and a second connecting wire 7 are further included, one end of the second connecting wire 7 is connected to the battery 6, the other end of the second connecting wire 7 is connected to the circuit board 4, and the second connecting wire 7 passes through the through hole 11, so that the earphones can be assembled into a wireless earphone for use due to the independent battery 6.

Further, the battery 6 and the sound emitting unit 2 are located on the same side of the through hole 11. The sound generating unit 2 is usually arranged in a larger cavity formed by the shell 1, and the battery 6 and the sound generating unit 2 are arranged together, so that the volume of the cavity can be fully utilized, the whole structure of the earphone is more compact, and smaller volume is obtained.
