Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0061] Usually, the back cavity of the earphone needs to be opened with an air vent to balance the internal and external pressures and improve the sound quality. However, due to the structural limitations of the air vent, the stability and consistency of the air venting in the back cavity are poor, and the instantaneous air flow impact is difficult to be effectively discharged through the air vent, which will affect the sound quality of the earphone.

[0062] In view of this, the earphone and earphone assembly provided by the utility model have an air leakage channel in the support shell group, the first end of the air leakage channel is connected to the back cavity, and the second end of the air leakage channel is connected to the air leakage hole, which improves the integrity of the air leakage channel, makes the back cavity in an open state, and the airflow discharged from the air leakage channel is more easily discharged through the air leakage hole, reducing the problem of airflow diffusing to the surroundings during the process of passing through the air leakage channel. The air leakage channel helps to balance the air pressure inside the back cavity and the surrounding environment, prevent pressure accumulation, improve the low-frequency acoustic performance of the speaker, and improve the sound effect of the earphone.

[0063] The earphone and earphone assembly provided by the embodiments of the present invention are described below with reference to the accompanying drawings.

[0064] refer to Figure 1 and Figure 2 As shown, the utility model provides an earphone, comprising:

[0065] A support shell assembly, wherein the support shell assembly has a mounting hole 312 and an air release channel 311;

[0066] The speaker 20 is arranged in the mounting hole 312 to separate the interior of the supporting shell group into a front cavity and a rear cavity. The outer wall of the rear cavity is provided with an air leakage hole 12. The first end of the air leakage channel 311 is connected to the rear cavity, and the second end of the air leakage channel 311 is connected to the air leakage hole 12.

[0067] The earphone provided by the utility model has an air leakage channel 311 in the support shell group, the first end of the air leakage channel 311 is connected to the back cavity, and the second end of the air leakage channel 311 is connected to the air leakage hole 12, so that the integrity of the air leakage channel 311 is improved, so that the back cavity is in an open state, and the airflow discharged from the air leakage channel 311 is more easily discharged through the air leakage hole 12, reducing the problem of airflow diffusing to the surroundings during the process of passing through the air leakage channel 311. The air leakage channel 311 is used to balance the air pressure inside the back cavity and the surrounding environment, prevent pressure accumulation, and is conducive to improving the low-frequency acoustic performance of the speaker to improve the sound effect of the earphone.

[0068] In a possible implementation, the housing 10 includes a lower cover 14 and an upper cover 15 that are buckled together. The lower cover 14 and the upper cover 15 can be fixed by buckling, bonding, etc. The lower cover 14 and the upper cover 15 together form a receiving cavity 11.

[0069] In one possible implementation, the support shell assembly includes a shell 10 and a bracket member 30 , the shell 10 has a receiving cavity 11 , the bracket member 30 is disposed in the receiving cavity 11 , the mounting hole 312 is located at the center of the bracket member 30 , and the vent hole 12 is opened on the side wall of the shell 10 .

[0070] In one possible implementation, the vent hole 12 may be opened on the side wall of the lower cover 14 . With this structure, the vent hole 12 is airtightly sealed around it, thus avoiding air leakage around it and facilitating the processing of the vent hole 12 .

[0071] In a possible implementation, the air leakage hole 12 may be a circular hole, an elliptical hole, a rectangular hole, a polygonal hole, etc., so as to allow air flow to pass through and have aesthetics.

[0072] In a possible implementation, the cross-sectional shape of the air leakage channel 311 may also be circular, elliptical, rectangular, polygonal, etc.

[0073] In a possible implementation, the first end of the air leakage channel 311 is located on the side wall of the mounting hole 312, and the first end of the air leakage channel 311 faces the speaker 20. The first end of the air leakage channel 311 faces the speaker 20, and the air leakage channel 311 can extend in a straight line direction. Reducing the length of the air leakage channel 311 helps to quickly release the air pressure in the back cavity, improve the low-frequency acoustic performance of the speaker 20, reduce noise, and enhance sound effects. The back cavity is connected to the air leakage hole 12 through the air leakage channel 311. When the airflow enters the air leakage hole 12 through the air leakage channel 311, the collision between the airflow and the cavity wall of the back cavity, which causes the problem of airflow being blocked, can be reduced, thereby improving the smoothness of the airflow.

[0074] In one possible implementation, reference Figure 3 , Figure 4 and Figure 5 As shown, the mounting hole 312 is located at the center of the bracket 30, the speaker 20 is located in the mounting hole 312, and the first end of the air leakage channel 311 is connected to the mounting hole 312. The mounting hole 312 is used to position the speaker 20. After the bracket 30 is installed, the air leakage channel 311 is connected to the mounting hole 312. The structure is simple and easy to produce and process.

[0075] In a possible implementation, the bracket member 30 includes a bracket body 31 and a flexible seal 32, the flexible seal 32 abuts between the bracket body 31 and the inner wall of the housing 10, and a through hole 323 connected to the air leakage hole 12 is provided in the flexible seal 32. The through hole 323 is used to allow airflow to pass smoothly.

[0076] In a possible implementation, the bracket body 31 is substantially ring-shaped, and a positioning column is disposed on one side of the bracket body 31 for positioning the speaker 20 and realizing the positioning of the bracket body 31 in the accommodating cavity 11 .

[0077] The bracket body 31 supports and fixes the speaker 20, and the flexible seal 32 blocks the gap between the bracket body 31 and the cavity wall of the rear cavity, thereby improving the sealing effect and preventing the air flow pressure from passing through the gap between the bracket body 31 and the cavity wall of the rear cavity.

[0078] The bracket body 31 can be a plastic part, which can stably support and fix the speaker 20. The flexible sealing member 32 can be made of a soft material with good sealing performance such as rubber and silicone, which has a certain elastic deformation ability and can be elastically deformed when squeezed, thereby achieving a sealing effect.

[0079] In one possible implementation, reference Figure 3 and Figure 6As shown, the bracket body 31 includes a limiting portion 313, which is arranged on the inner wall surface of the mounting hole 312 and extends to the side edge of the speaker 20 facing the rear cavity. The side edge of the speaker 20 facing the rear cavity abuts against the limiting portion 313, thereby limiting the installation depth of the speaker 20 in the mounting hole 312.

[0080] In one possible implementation, reference Figure 2 and Figure 4 As shown, the flexible seal 32 includes a sealing portion 321 and a connecting portion 322. The sealing portion 321 abuts against a side of the bracket body 31 facing the shell 10. The connecting portion 322 is connected to the sealing portion 321. The connecting portion 322 is arranged on the inner wall surface of the air leakage channel 311, and the through hole 323 is opened in the connecting portion 322.

[0081] With such a structure, under the joint extrusion of the inner wall of the shell 10 and the bracket body 31 , the sealing portion 321 undergoes elastic deformation, thereby filling the gap between the bracket body 31 and the shell 10 , thereby achieving a sealing effect between the bracket body 31 and the shell 10 .

[0082] In one possible implementation, reference Figure 7 and Figure 8 As shown, the sealing portion 321 and the connecting portion 322 can be an integral structure formed in one piece, and the connecting portion 322 can also be connected to the inner wall surface of the air leakage channel 311 by gluing. The connecting portion 322 is arranged on the inner wall surface of the air leakage channel 311, which can improve the stability of the connection between the flexible sealing member 32 and the bracket body 31, thereby improving the stability of the seal.

[0083] In a possible implementation, in order to improve the sealing effect, a protrusion 324 is provided on a surface of the sealing portion 321 facing the air leakage hole 12 , and the protrusion 324 abuts against the inner wall surface of the shell 10 .

[0084] In one possible implementation, the raised portion 324 may be a circle of ridges located at the edge of the air leakage hole 12, or the raised portion 324 may be a plurality of raised points located at the edge of the air leakage hole 12. Under the joint extrusion of the bracket body 31 and the shell 10, the raised portion 324 and the sealing portion 321 are deformed, thereby achieving sealing between the bracket body 31 and the shell 10, which is beneficial to improving the sealing and air tightness.

[0085] In a possible implementation, the bracket body 31 and the lower cover 14 are an integral structure connected in one piece, and there is no need to assemble the bracket body 31 and the lower cover 14, thereby improving production efficiency.

[0086] In one possible implementation, the bracket body 31 and the shell 10 are relatively independent structures, and the bracket component 30 is formed by two-color injection molding, which eliminates the need for assembly of the bracket body 31 and the flexible seal 32, and enhances the stability of the connection between the bracket body 31 and the flexible seal 32 so that they will not fall off easily.

[0087] In a possible implementation, two air leakage channels 311 are provided in the bracket body 31 , and the two air leakage channels 311 are respectively located on two opposite inner walls of the bracket body 31 , which is beneficial to improving the air leakage efficiency and thus improving the low-frequency sound quality.

[0088] In one possible implementation, reference Figure 2 and Figure 6 As shown, the earphone provided by the utility model further includes a filter assembly 40, which includes a hard net 41, which is arranged on the outer wall of the supporting shell assembly and blocks the outer end of the air leakage hole 12.

[0089] In this embodiment, the filter assembly 40 is arranged on the outer wall of the shell 10, the appearance of the shell 10 is more beautiful, and the appearance of the shell 10 is prevented from forming grooves, and has better waterproofness and airtightness.

[0090] The inner wall of the housing 10 protrudes into the accommodating cavity 11 at the position of the air leakage hole 12 , which is equivalent to extending the length of the rear cavity air leakage channel 311 .

[0091] In one possible implementation, the edge of the hard net 41 has a bending portion 411 that bends toward the inner side of the supporting shell group; the outer wall of the supporting shell group is also provided with a connecting groove 13, the connecting groove 13 is arranged on the side of the air leakage hole 12, the bending portion 411 is arranged in the connecting groove 13, and the hard net 41 is relatively fixed to the supporting shell group.

The bending portion 411 can be pasted in the connecting groove 13, or the bending portion 411 can be connected to the connecting groove 13 by ultrasonic welding, so as to improve the stability of the fixation between the hard net 41 and the shell 10 and improve the aesthetic appearance of the shell 10.

[0093] The hard net 41 can be a metal net, such as a steel net, which has a certain hardness and can play a good blocking and protection effect. It is easy to understand that the hard net 41 has a plurality of meshes, so that the airflow can pass smoothly.

[0094] In a possible implementation, the connection groove 13 is arranged along the circumference of the air leakage hole 12. With such a structure, after the bending portion 411 is arranged in the connection groove 13, the edge of the hard net 41 can be effectively prevented from curling and other problems, thereby improving the stability of the fixation between the hard net 41 and the housing 10 and ensuring stable waterproofness.

[0095] In a possible implementation, the filter assembly 40 further includes a flexible net 42, which blocks the end of the air leakage hole 12 facing the hard net 41. The hard net 41 has a protective effect on the flexible net 42, and the flexible net 42 can not only filter air impurities and dust outside the air leakage hole 12, but also adjust the air sound resistance in the rear cavity of the speaker 20 to a certain extent, thereby improving the sound quality.

[0096] The flexible net 42 can be bonded to the end of the air vent 12 facing the hard net 41 by double-sided tape or other colloids. In order to prevent the flexible net 42 from protruding, a sink 16 can be set at the end of the air vent 12 facing the hard net 41, and the flexible net 42 can be pasted on the bottom wall of the sink 16.
