[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0034] like Figures 1 to 4As shown, the embodiment of the utility model provides an in-ear earphone 1000, which includes an earphone body 100 and a first damping adjusting member 200, wherein the earphone body 100 is provided with a front cavity 110 and a rear cavity 120, and the earphone body 100 is also provided with a first tuning hole 130 and a second tuning hole 140, the front cavity 110 is connected to the outside through the first tuning hole 130, and the rear cavity 120 is connected to the outside through the second tuning hole 140; a through groove 1211 is provided on the cavity wall of the rear cavity 120, and the through groove 1211 connects the front cavity 110 and the rear cavity 120; the first damping adjusting member 200 is installed at the through groove 1211, and the first damping adjusting member 200 is used to adjust the air permeability. The in-ear earphone 1000 can effectively improve the sound quality of the earphone by providing a connecting through groove 1211 between the front cavity 110 and the rear cavity 120, and the user has a better experience.

[0035] Specifically, the earphone body 100 is provided with a front cavity 110 and a rear cavity 120, both of which can improve the sound performance of the earphone to a certain extent. At the same time, the earphone body 100 is also provided with a first tuning hole 130 and a second tuning hole 140, so that the relatively closed front cavity 110 and the rear cavity 120 can be connected to the outside world respectively, so as to balance the internal air pressure of the front cavity 110 or the rear cavity 120, and avoid the internal pressure from interfering with the vibration sound of the earphone, thereby preliminarily improving the sound quality. However, due to the high-frequency vibration characteristics of the earphone diaphragm, only adjusting the air pressure of the front cavity 110 and the rear cavity 120 through the first tuning hole 130 and the second tuning hole 140 may still cause the problem that the pressure cannot be balanced in time, thereby hindering the vibration sound of the earphone, and by providing a through groove 1211 to connect the front cavity 110 and the rear cavity 120, the internal air pressure of the front cavity 110 and the rear cavity 120 can be more effectively balanced, the damping of the diaphragm can be reduced, and the sound quality can be further improved. In addition, the present application also sets a first damping adjustment member 200 at the through groove 1211 to control the air permeability after the front cavity 110 and the rear cavity 120 are connected, so as to maintain the internal pressure of the front cavity 110 and the rear cavity 120 within the required range, and tune the in-ear earphone 1000 so that the sound quality of the in-ear earphone 1000 can be at a higher level.

[0036] In the present application, the front cavity 110 and the rear cavity 120 can be formed integrally with the earphone body 100 or can be formed by a combination of components. The shapes of the front cavity 110 and the rear cavity 120 can be designed according to actual needs and are not limited here. The space occupied by the rear cavity 120 is larger than that of the front cavity 110, which is convenient for arranging electronic components.

[0037] In the present application, in addition to adjusting the sound quality, the first tuning hole 130 can also relieve pressure. It can effectively improve the ear canal soreness and eardrum fatigue caused by the increase in air pressure in the closed space formed by the front cavity 110 of the earphone and the eardrum and ear canal when wearing the earphones for a long time, and effectively prevent the deformation of the diaphragm caused by the inability of air pressure to leak out during wearing, thereby enhancing the user experience. The shape and size of the first tuning hole 130 and the second tuning hole 140 can be adjusted according to needs and are not limited here. For example, in the present application, the first tuning hole 130 and the second tuning hole 140 are both circular. Circular tuning holes can better control the air permeability and are more convenient to process.

[0038] Reference Figure 3 and Figure 4 In one embodiment, a sound outlet hole 150 is provided on the earphone body 100, a groove 160 is provided inside the earphone body 100, and the sound outlet hole 150 is arranged at the bottom of the groove 160. The in-ear earphone 1000 also includes a dynamic coil assembly 300, and the dynamic coil assembly 300 is sealed and installed at the notch of the groove 160 to form a front cavity 110 and a rear cavity 120. The cavity wall includes a rear cavity bottom wall 121 adjacent to the groove 160, and a through groove 1211 is opened in the rear cavity bottom wall 121, and the through groove 1211 is connected to the groove wall of the groove 160. Specifically, the groove 160 is used to limit and fix the dynamic coil assembly 300, and the dynamic coil assembly 300 is sealed at the notch of the groove 160 by glue, so that the earphone body 100 is separated into the front cavity 110 and the rear cavity 120 by the dynamic coil assembly 300, so that the processing difficulty of the front cavity 110 and the rear cavity 120 is smaller. The sound outlet is arranged at the bottom of the groove 160, so that the dynamic coil assembly 300 installed at the groove 160 can be aligned with the sound outlet, which is more conducive to sound transmission. The through groove 1211 is opened on the bottom wall of the rear cavity 120 to facilitate processing and forming together with the groove 160, reducing the processing difficulty.

[0039] Specifically, the shape of the groove 160 is adapted to the dynamic coil assembly 300 to improve the sealing performance of the two. For example, in this embodiment, the groove 160 is circular. And a limiting boss is also provided at the groove wall of the groove 160, which can separate the dynamic coil assembly 300 from the sound outlet to stably form the front cavity 110, making the assembly more accurate.

[0040] Reference Figure 5In one embodiment, the through slot 1211 includes a first accommodating portion 1211a and a second accommodating portion 1211b arranged in sequence in the direction in which it is opened. The outer contour of the first accommodating portion 1211a is larger than the outer contour of the second accommodating portion 1211b to form a mounting step 1211c, and the first damping adjustment member 200 is mounted on the mounting step 1211c. The front cavity 110 and the rear cavity 120 are connected through the second accommodating portion 1211b. The first accommodating portion 1211a is used to limit the first damping adjustment member 200. The two form the mounting step 1211c to provide a support and fixed installation position for the first damping adjustment member 200 to prevent the first damping adjustment member 200 from being dislocated and falling off, affecting the control of the air permeability, and even causing the tuning function to fail. This design makes the tuning reliability of the in-ear earphone 1000 better.

[0041] Specifically, the first accommodating portion 1211a and the second accommodating portion 1211b are countersunk elongated holes, and the outer contour of the first accommodating portion 1211a is adapted to the shape of the first damping adjusting member 200 to better limit and install the first damping adjusting member 200. The first damping adjusting member 200 can be fixed to the installation step 1211c by bonding, and the assembly is faster and more convenient.

[0042] In one embodiment, the first damping adjustment member 200 is made of a material with adjustable air permeability. For example, in this embodiment, the first damping adjustment member 200 is made of nylon mesh. Nylon mesh has certain flexibility and plasticity, and can be cut and shaped according to design requirements, and has stronger adaptability.

[0043] Reference Figure 1 and Figure 4 In one embodiment, the first tuning hole 130 and the second tuning hole 140 are disposed on the same side of the earphone body 100. In this way, the first tuning hole 130 and the second tuning hole 140 can be processed continuously on the same side of the earphone body 100, and no additional process is required to change the surface and fix it during the manufacturing process, which saves process steps and reduces manufacturing complexity.

[0044] Reference Figure 1 In one embodiment, a first guide groove 180 and a second guide groove 190 are further provided on the same side of the earphone body 100, and the first tuning hole 130 is provided at the bottom of the first guide groove 180, and the second tuning hole 140 is provided at the bottom of the second guide groove 190. With such a configuration, when worn, even if the skin of the concha cavity fits the earphone body 100, the first guide groove 180 and the second guide groove 190 can separate the skin of the concha cavity from the first tuning hole 130 and the second tuning hole 140, thereby preventing the skin from blocking the first tuning hole 130 and the second tuning hole 140, and keeping the first tuning hole 130 and the second tuning hole 140 unobstructed, thereby ensuring stable sound quality.

[0045] Reference Figure 3 and Figure 4 In one embodiment, the in-ear earphone 1000 further includes a second damping adjustment member 400, which is installed on the side of the first tuning hole 130 close to the front cavity 110; and / or, further includes a third damping adjustment member 500, which is installed on the side of the second tuning hole 140 close to the rear cavity 120. In this way, the air permeability of the front cavity 110 or the rear cavity 120 in communication with the outside world can be controlled to maintain the internal pressure of the front cavity 110 and the rear cavity 120 within the required range, and the in-ear earphone 1000 is further tuned to achieve the required sound quality.

[0046] Specifically, the second damping adjustment member 400 and the third damping adjustment member 500 are made of the same material as the first damping adjustment member 200, and nylon mesh is used. The first tuning hole 130 and the second tuning hole 140 are provided with a boss on the side facing the inside of the earphone body 100 to facilitate the positioning and installation of the second damping adjustment member 400 and the third damping adjustment member 500. The installation method of the second damping adjustment member 400 and the third damping adjustment member 500 is the same as that of the first damping adjustment member 200, and bonding can be used.

[0047] In one embodiment, the air permeability of the first damping adjustment member 200, the second damping adjustment member 400, and the third damping adjustment member 500 is greater than or equal to 300 L / ㎡·S and less than or equal to 2000 L / ㎡·S. The air permeability can effectively adjust the pressure inside the earphone within a certain range while reducing the damping of the diaphragm, thereby freely and flexibly adjusting the sound quality performance of the in-ear earphone 1000, and the in-ear earphone 1000 has better applicability and flexibility.

[0048] Reference Figure 1 In one embodiment, the earphone body 100 is further provided with a card slot 170; the in-ear earphone 1000 further includes a charging contact 600, which is installed inside the earphone body 100 and at least partially exposed at the bottom of the card slot 170. The card slot 170 can cooperate with the charging compartment to limit the in-ear earphone 1000, so that the charging contact 600 can be accurately aligned with the charging compartment and electrically connected to avoid the situation where normal charging cannot occur.

[0049] Reference Figure 1In one embodiment, the card slot 170 is connected to the first guide slot 180, and / or the card slot 170 is connected to the second guide slot 190. In this way, the first guide slot 180 and the second guide slot 190 are both connected to the card slot 170, and the card slot 170 has a large area connected to the outside world, and the skin is less likely to contact and fit, further effectively preventing the first tuning hole 130 or the second tuning hole 140 from being blocked, so as to maintain good sound quality and provide users with a better listening experience.

[0050] Specifically, the first guide groove 180 includes a first groove section 181 and a second groove section 182. The first groove section 181 is arranged on a side of the second groove section 182 away from the slot 170. One end of the first groove section 181 is provided with a first tuning port, and the other end is connected to one end of the second groove section 182. The other end of the second groove section 182 passes through the groove wall of the slot 170. Similarly, the setting method of the second guide groove 190 is consistent with that of the first guide groove 180, which will not be repeated here.

[0051] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
