In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1 As shown, the present application involves an earphone, wherein the earphone is a smart earphone, and at the same time, the earphone can be an open earphone or an in-ear earphone, the earphone can be a wired earphone or a TWS earphone, wherein the earphone can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function, and at the same time, it can also be configured with stereo surround and other functions.

[0034] Combination Figure 1 and Figure 2 The earphone includes an ear shell 100, a speaker 200, a bracket 300 and a circuit board 400.

[0035] The ear shell 100 is a hollow structure. The speaker 200, the bracket 300 and the circuit board 400 are all arranged in the ear shell 100. The ear shell 100 can provide an installation position and can protect the devices arranged inside it.

[0036] The speaker 200 is disposed in the ear shell 100 and is capable of producing sound. Figure 2 Only a partial structure of the speaker 200 is shown. The side where the diaphragm of the speaker 200 is located is the front end of the speaker 200.

[0037] The bracket 300 is arranged in the ear shell 100 and surrounds the side of the rear end of the speaker 200. A speaker rear cavity 101 arranged around the rear end of the speaker 200 is formed between the bracket 300 and the rear end of the speaker 200. The bracket 300 has an avoidance hole 310 arranged opposite to the rear end of the speaker 200 and connected to the speaker rear cavity 101. The rear end of the speaker 200 extends into the avoidance hole 310.

[0038] It should be noted that the rear end of the speaker 200 extends into the avoidance hole 310 means that the rear end of the speaker 200 extends into the avoidance hole 310 and does not extend from the avoidance hole 310 .

[0039] Combination Figure 2 and Figure 3It can be understood that the bracket 300 is a hollow structure with a cavity 340. The bracket 300 is fixedly arranged inside the ear shell 100 and can support the speaker 200. The bracket 300 is covered at the rear end of the speaker 200, and a speaker rear cavity 101 is formed between the inner side wall of the bracket 300 and the side wall of the rear end of the speaker 200. In addition, by providing an avoidance hole 310 on the bracket 300 for the rear end of the speaker 200 to penetrate, the space occupied by the speaker 200 and the bracket 300 as a whole in the thickness direction of the earphone can be reduced, thereby reducing the thickness of the entire earphone.

[0040] It can be further understood that, in the absence of the avoidance hole 310, in order to prevent the bracket 300 from interfering with the rear end of the speaker 200, the bracket 300 must be moved backwards. In this way, the whole formed by the bracket 300 and the speaker 200 occupies a larger space in the thickness direction of the earphone, thereby increasing the thickness of the earphone.

[0041] The circuit board 400 is disposed in the ear shell 100 and is located at the rear side of the speaker 200 . The circuit board 400 seals the avoidance hole 310 .

[0042] It can be understood that the circuit board 400 seals the avoidance hole 310, which can reduce the risk of sound waves in the speaker rear cavity 101 leaking out through the avoidance hole 310, thereby ensuring the sound quality; in addition, the circuit board 400 is a necessary component of the earphone, and by using the existing circuit board 400 to seal the avoidance hole 310, the problem of increasing the thickness of the earphone due to adding new components to seal the avoidance hole 310 is avoided.

[0043] The circuit board 400 is also electrically connected to the speaker 200 , and the circuit board 400 can control the speaker 200 .

[0044] like Figure 5 As shown, in some embodiments, the speaker 200 and the circuit board 400 are electrically connected via an elastic conductive column 410 .

[0045] Specifically, the elastic conductive column 410 is a PIN pin, and the elastic conductive column 410 is fixed on the circuit board 400. In this way, after the speaker 200 and the circuit board 400 are assembled, the elastic conductive column can directly abut against the conductive terminal on the speaker 200, thereby realizing the electrical connection between the circuit board 400 and the speaker 200, which can reduce the difficulty of assembly and improve the assembly efficiency.

[0046] More specifically, if Figure 3 , Figure 4 As shown, the elastic conductive column 410 is fixed on a side of the circuit board 400 close to the bracket 300 . The bracket 300 is provided with an escape groove 350 . The elastic conductive column 410 passes through the escape groove 350 and is electrically connected to the speaker 200 .

[0047] It should be noted that the circuit board 400 can also seal the avoidance groove 350 to reduce the risk of sound waves in the speaker rear cavity 101 leaking through the avoidance groove 350 and ensure the sound quality.

[0048] Of course, in some other embodiments, the speaker 200 and the circuit board 400 may also be electrically connected via a flexible circuit board or a wire.

[0049] It should be noted that the circuit board 400 sealing the avoidance hole 310 means that the circuit board 400 blocks the avoidance hole 310 .

[0050] In some embodiments, the circuit board 400 and the bracket 300 abut against each other to form a sealing structure for sealing the avoidance hole 310; in other embodiments, a sealing ring is arranged between the circuit board 400 and the bracket 300 to form a sealing structure for sealing the avoidance hole 310; in still other embodiments, a sealant is arranged between the circuit board 400 and the bracket 300 to form a sealing structure for sealing the avoidance hole 310.

[0051] Furthermore, the edge of the avoidance hole 310 at one end away from the speaker 200 is sealed with the circuit board 400 , thereby further improving the sealing effect of the avoidance hole 310 .

[0052] The rear end of the speaker 200 is spaced from the circuit board 400. It is understandable that after the rear end of the speaker 200 extends into the avoidance hole 310, it does not directly contact the circuit board 400, but leaves a gap between the rear end of the speaker 200 and the circuit board 400. In this way, it is possible to avoid pressure between the rear end of the speaker 200 and the circuit board 400, thereby preventing the circuit board 400 from being damaged.

[0053] In some embodiments, an elastic pad may be provided at the rear end of the speaker 200, and the elastic pad is spaced apart from and arranged opposite to the circuit board 400. In this way, in some cases, such as when the earphone falls or is subjected to a large vibration and causes the speaker 200 or the circuit board 400 to vibrate, the rear end of the speaker 200 can be prevented from directly colliding with the circuit board 400, and the elastic pad can play a buffering role, reducing the risk of damage to the circuit board 400.

[0054] Combination Figure 2 , Figure 3 and Figure 4 In some embodiments, the bracket 300 is further formed with a bass channel 320 communicating with the speaker rear cavity 101 .

[0055] It is understandable that when the speaker 200 is working, the sound waves emitted by the speaker 200 will not only radiate from the front, but also partially radiate from the rear into the speaker rear cavity 101. By setting a bass channel 320 connected to the speaker rear cavity 101 on the bracket 300, the sound waves entering the speaker rear cavity 101 can be utilized, especially the heavy bass part.

[0056] In the traditional solution, a bass reflex tube is specially provided to utilize the sound waves of the speaker rear cavity 101. However, in the earphone of the present application, by providing a bass channel 320 on the bracket 300, there is no need to add a bass reflex tube, which can effectively reduce the cost and difficulty of assembling the earphone.

[0057] It should be noted that a bass hole is provided on the ear shell 100, one end of the bass channel 320 is connected to the speaker rear cavity 101, and the other end is arranged opposite to the bass hole, so that the sound coming out of the bass channel 320 can be transmitted to the outside.

[0058] Furthermore, the bracket 300 has an extension portion 330 constituting the bass channel 320 , which extends toward the bass hole and connects one end of the bass channel 320 away from the speaker rear cavity 101 with the bass hole, and the extension portion 330 is sealed against the inner end of the bass hole.

[0059] It should be noted that the extension part 330 is provided with a bass channel 320. By making the extension part 330 seal around the inner end of the bass hole, the risk of sound waves leaking through the gap between the extension part 330 and the inner wall of the ear shell 100 can be reduced, thereby ensuring the sound quality.

[0060] In other embodiments, a sealing ring is provided between the extension portion 330 and the inner wall of the ear shell 100, and the sealing ring surrounds the inner end of the bass hole. In this way, the risk of sound waves leaking through the gap between the extension portion 330 and the inner wall of the ear shell 100 can also be reduced; in some other embodiments, a sealant is provided between the extension portion 330 and the inner wall of the ear shell 100, and the sealant surrounds the inner end of the bass hole. In this way, the risk of sound waves leaking through the gap between the extension portion 330 and the inner wall of the ear shell 100 can also be reduced.

[0061] like Figure 1 As shown, in some embodiments, a tuning net 500 covering the bass hole is provided at the bass hole. The tuning net 500 can play a tuning role, and in addition, the tuning net 500 can also play a dustproof role.

[0062] In some embodiments, a positioning step is provided on the side of the speaker 200, and the front end of the bracket 300 is positioned and matched with the positioning step. In this way, the positioning effect of the speaker 200 and the bracket 300 can be improved, and the assembly accuracy of the speaker 200 and the bracket 300 can be ensured.

[0063] like Figure 1 As shown, in some embodiments, the earphone further includes an ear hook 600 connected to the ear shell 100 , so that the user can wear the earphone on the ear through the ear hook 600 .

[0064] It should be noted that when the user wears the earphones of the present application, the angle between the bass hole and the vertical direction is between 0-45°, which can reduce the risk of sound leakage.

[0065] In the earphone of the present application, the ear shell 100 is a hollow structure, and the speaker 200, the bracket 300 and the circuit board 400 are all arranged in the ear shell 100. The ear shell 100 can provide an installation position and can protect the components arranged inside it; the speaker 200 is arranged in the ear shell 100 and can make sounds; the bracket 300 is a hollow structure with a cavity 340, and the bracket 300 is fixedly arranged inside the ear shell 100, which can support the speaker 200. Among them, the bracket 300 covers the rear end of the speaker 200, and a speaker rear cavity 101 is formed between the inner side wall of the bracket 300 and the side wall of the rear end of the speaker 200. In addition, by setting an avoidance hole 310 on the bracket 300 for the rear end of the speaker 200 to penetrate, the space occupied by the speaker 200 and the bracket 300 as a whole in the thickness direction of the earphone can be reduced, thereby reducing the thickness of the entire earphone. In addition, the circuit board 400 seals the avoidance hole 310, which can reduce the risk of sound waves in the speaker rear cavity 101 leaking out through the avoidance hole 310, ensuring the sound quality; and the circuit board 400 is a necessary component of the earphone. By using the existing circuit board 400 to seal the avoidance hole 310, it also avoids the problem of increasing the thickness of the earphone due to the addition of a new component to seal the avoidance hole 310. Further, when the speaker 200 is working, the sound waves emitted by the speaker 200 will not only radiate from the front, but also radiate from the rear into the speaker rear cavity 101. By setting a bass channel 320 connected to the speaker rear cavity 101 on the bracket 300, the sound waves entering the speaker rear cavity 101 can be utilized, especially the heavy bass part. In the traditional solution, a reversing tube is specially set to utilize the sound waves of the speaker rear cavity 101. In the earphone of the present application, by setting the bass channel 320 on the bracket 300, there is no need to add a reversing tube, which can effectively reduce the cost and assembly difficulty of the earphone.
