[0038] Please refer to Figures 1 to 6 It shows the specific structure of the preferred embodiment of the utility model, including earphone shell 10, loudspeaker module 20, FPC 30 and bass plate 40.

[0039] The earphone shell 10 includes the loudspeaker end 11, the bridge 12 and the battery end 13 connected integrally in sequence, the loudspeaker end 11 has the loudspeaker cavity 111 inside, and the front side and the rear side of the loudspeaker end 11 are provided with the sound outlet 112 and the air vent 113 respectively, the sound outlet 112 and the air vent 113 are both communicated with the loudspeaker cavity 111, the circumferential side of the air vent 113 is provided with the step 14, and the battery (not shown in the figure) is arranged in the battery end 13; in the embodiment, the steel mesh 15 is arranged on the sound outlet 112, and the tuning mesh 16 is arranged on the air vent 113; and the earphone shell 10 includes the front shell 101 and the rear shell 102, the front shell 101 and the rear shell 102 are mutually spliced and fixed and surround to form the aforementioned loudspeaker cavity 111, the aforementioned sound outlet 112 is arranged on the front shell 101, and the aforementioned air vent 113 is arranged on the rear shell 102; and the inner side of the step 14 extends the convex part 141.

[0040] The loudspeaker module 20 is arranged in the loudspeaker cavity 111, and the loudspeaker diaphragm 21 of the loudspeaker module 20 is close to the sound outlet 112.

[0041] One end of the FPC 30 extends into the loudspeaker cavity 111 and is connected with the loudspeaker module 20, and the other end of the FPC 30 extends into the battery end 13 through the inside of the bridge 12 and is connected with the battery in the battery end 13.

[0042] The bass plate 40 is arranged in the loudspeaker cavity 111, and the edge of the bass plate 40 is in close contact with the step 14. The bass plate 40, together with the step 14 and the end face of the loudspeaker cavity 111, cooperatively forms a bass channel 401. The input end of the bass channel 401 is in communication with the loudspeaker cavity 111, and the output end of the bass channel 401 is in communication with the sound outlet 112. The outer edge of the bass plate 40 is designed to be just capable of being placed on the step 14 and is positioned by the edge of the step 14, so as to ensure the assembly. In this embodiment, the edge of the bass plate 40 is fixedly connected with the step 14 by gluing. The bass channel 401 is sealed, so as to ensure that the formed bass channel 401 will not have the problem of air leakage. Thus, the sound pressure can only pass through the bass channel 401 and then pass through the air vent 113, so as to be in communication with the external environment. Further, the edge of the bass plate 40 is in close contact with the convex part 141. The design of the convex part 141 can limit the bass plate, so that the assembly of the bass plate 40 is more accurate. After the assembly of the bass plate 40 is completed, a glue gun is used to coat a circle of glue in the gap between the bass plate 40 and the convex part 141 by using a glue needle. This not only makes the assembly of the bass plate 40 more firm and reliable, but also realizes the sealing of the bass channel 401. The bass plate 40 is provided with a reinforcing rib 41, which can better prevent deformation of the material during transportation and operation. The bass plate 40 is in L shape. In addition, the bass plate 40 is made of metal material, specifically, stainless steel material and is formed by stamping. The thickness of the bass plate 40 is greater than 0.2 mm. The thicker the material is, the less likely the bass plate 40 is deformed, so as to better ensure the consistency of the acoustic performance. The cross section of the bass channel 401 is in strip shape, which is different from the conventional design in circular or approximately square shape. Since the internal volume of the earphone is limited, the bass channel 401 is designed to be a bass channel with a cross section in strip shape. This can avoid occupying too much space in the loudspeaker cavity 111, so as to obtain a larger internal cross section of the bass channel 401 while ensuring the volume of the bass channel 401. In addition, the bass plate 40 is designed to be as low and short as possible, so as to avoid interference with other parts.

[0043] The assembly process of this embodiment is described as follows:

[0044] First, the steel mesh 15 is arranged on the sound outlet 112, the tuning mesh 16 is arranged on the air hole 113, then, the loudspeaker module 20 and the battery are respectively installed in the loudspeaker cavity 11 and the battery end 13, one end of the FPC 30 is inserted into the loudspeaker cavity 111 and connected with the loudspeaker module 20, the other end of the FPC 30 is inserted into the battery end 13 through the inside of the bridge 12 and connected with the battery in the battery end 13, then, the bass plate 40 is arranged on the step 14, the edge of the bass plate 40 is in close contact with the convex part 141, the convex part 141 limits the bass plate 40, then, the glue is applied on the gap between the bass plate 40 and the convex part 141 by using the glue applying needle, finally, the front shell 101 and the rear shell 102 are spliced and fixed, and the OWS earphone with excellent bass performance is obtained.

[0045] The OWS earphone with excellent bass performance is tested and compared with the earphone with the same configuration and without the bass plate, 100Hz is taken as the base point, the 45CA simulation ear system is adopted for the test and comparison, and the test results are shown in Figure 7 The test curve of the OWS earphone with excellent bass performance is red, and the test curve of the earphone with the same configuration and without the bass plate is blue, and it can be obviously seen from the comparison that the OWS earphone with excellent bass performance is about 2dB higher, so it is proved that the bass channel design in the OWS earphone with excellent bass performance is effective in practice and plays a role in improving the bass, and the role is obvious.

[0046] The design emphasis of the utility model lies in: through setting the bass plate in the loudspeaker cavity, the edge of the bass plate is in close contact with the step, the bass plate and the step and the end face of the loudspeaker cavity jointly form the bass channel, the input end of the bass channel is communicated with the loudspeaker cavity, the output end of the bass channel is communicated with the sound outlet, so that the sound pressure behind the loudspeaker module can only be discharged through the bass channel, the purpose of attenuating the high frequency with short wavelength is achieved, and the low frequency component with long wavelength will not be affected, but directly discharged through the bass channel and will not produce resonance, frequency resonance can be produced in the very low frequency band, such as 100-300Hz, the effect of low frequency enhancement is realized, the feeling is real and will not cause distortion, meanwhile, the space occupied by the bass plate is very small, and the utility model is suitable for OWS earphone.

[0047] The above is only the preferred embodiment of the utility model, and does not limit the technical range of the utility model, so any slight modification, equivalent change and modification according to the technical essence of the utility model are still within the range of the technical scheme of the utility model.
