[0002] The use of headphones has become a trend, but in places with noisy environments such as buses, subways, airports, and commercial streets, there is often a lot of noise. When users listen to audio, the loud background noise often enters the ear canal and affects the listening effect. Among them, there are usually two methods of noise reduction for headphones: active noise reduction and passive noise reduction. Active noise reduction mainly refers to the noise reduction system generating reverse sound waves equal to the external noise to neutralize the noise, thereby achieving the effect of noise reduction; passive noise reduction headphones mainly refer to forming a closed space by surrounding the ears, or using sound insulation materials such as silicone earplugs to block external noise.

[0003] Taking semi-in-ear active noise-cancelling headphones as an example, such noise-cancelling headphones currently launched by major companies usually require a microphone to be installed in the sound cavity to collect external noise sources for noise elimination processing, and both the microphone and the speaker are installed in the sound cavity of the headphones. However, in order to avoid affecting the sound pickup effect of the microphone, in the prior art, some headphones will set isolation brackets or baffles and other structures in the sound cavity to separate the sound cavity into two cavities. However, in this way, affected by mold manufacturing, product injection molding, internal space of the sound cavity, etc., the microphone often cannot be flexibly and reasonably arranged.

The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] It should be noted that the earphone 100 is mainly a noise reduction earphone, and of course, it can also be an ordinary earphone 100. In addition, the structure of the earphone 100 is mainly applicable to semi-in-ear earphones 100, and can also be applicable to other suitable types of earphones 100. The earphone 100 can be applied to almost all smart electronic products.

[0048] An embodiment of the present invention provides an earphone 100, such as Figures 2 to 7 As shown, the earphone 100 includes an inner shell 1, a noise reduction component 2, a front ear shell 4, a speaker 5 and a rear ear shell component 6. Figure 6 As shown, the noise reduction component 2 is disposed on the outer wall of the inner shell 1 to form a combined component 3. Figure 3 and Figure 6 As shown, a component 3 is provided on the inner wall of the pre-auricular shell 4. Figure 3 and Figure 4 As shown, the speaker 5 is arranged on the inner wall of the front ear shell 4 on the inner side of the inner shell 1; the rear ear shell component 6 is covered on the front ear shell 4, and together with the front ear shell 4, a accommodating cavity 200 is formed, and the accommodating cavity 200 contains the inner shell 1, the noise reduction component 2 and the speaker 5.

[0049] It should be noted that the “inner wall” mentioned in this article refers to the shell wall on the side close to the rear-ear shell component 6, and correspondingly, the “outer wall” mentioned refers to the shell wall on the side away from the rear-ear shell component 6.

[0050] like Figure 1 , Figure 5 , Fig. 9 and Fig.10 As shown, the inner shell 1 is provided with a main sound outlet 121. Figure 4 As shown, a sound cavity (not shown) is formed between the inner wall of the inner shell 1 and the speaker 5 , and the main sound outlet hole 121 and the sound cavity are communicated to form a main sound outlet channel 300 .

[0051] Correspondingly, if Figure 1 , Figure 5 and Fig. 9 As shown, the inner shell 1 is also provided with a sound pickup hole 122, and the outer wall of the inner shell 1 is provided with a groove 11. Figure 3 As shown, the sound pickup hole 122 is connected to the groove 11 by opening a hole on the groove 11 to form a sound pickup channel 400. The sound pickup channel 400 is separated from the main sound output channel 300 by the inner shell 1. In this way, the microphone 21 will no longer pick up the sound emitted by the speaker 5, but directly pick up the sound wave signal of the ear canal from the sound pickup channel 400, thereby reducing the interference of the environment on the sound pickup of the microphone 21, which is conducive to improving the overall noise reduction effect of the earphone 100.

[0052] like Figure 1 , Figure 5 and Figure 6 As shown, an avoidance hole 41 is provided on the pre-ear shell 4 at the position corresponding to the main sound outlet 121 and the sound pickup hole 122. It should be noted that the main sound outlet 121 and the sound pickup hole 122 can correspond to one avoidance hole respectively, or can share one avoidance hole 41. Specifically, in this embodiment, both share one avoidance hole 41.

[0053] like Figure 3 , Figure 5 and Figure 8 As shown, in order to achieve the noise reduction effect, the noise reduction component 2 generally includes a microphone 21, and a sound pickup through hole 211 is provided on the microphone 21. Figure 3As shown, the microphone 21 is accommodated in the groove 11, and the sound pickup through hole 211 is connected to the sound pickup channel 400. In this way, on the one hand, the noise reduction component 2 can pick up the sound wave signal in the ear canal from the sound pickup channel 400 through the sound pickup through hole 211 to perform noise reduction processing; on the other hand, because the speaker 5 is located on the inner side of the inner shell 1, the microphone 21 is located on the outer side of the inner shell 1, that is, the microphone 21 and the speaker 5 are separated by the inner shell 1. Therefore, the layout of the microphone 21 is no longer restricted by the space and pattern of the sound cavity (specifically, it can be the main sound output channel 300), and will not even be affected by the mold, molding, etc. The groove 11 can be formed at almost any position on the outer wall of the inner shell 1 to place the microphone 21. Obviously, the layout of the microphone 21 can be more flexible and reasonable.

[0054] Specifically in this embodiment, the installation steps of the earphone 100 are roughly as follows: 1) The noise reduction component 2 is attached to the outer wall of the inner shell 1 to form an assembly 3, and then the assembly 3 is set on the inner wall of the front ear shell 4, wherein the main sound outlet 121 and the sound pickup hole 122 should be ensured to be correspondingly connected with the avoidance hole 41; 2) On the inner side of the inner shell 1, the speaker 5 is set on the inner wall of the front ear shell 4 to ensure that a sound cavity is formed; 3) On one side of the speaker 5, the rear ear shell assembly 6 is covered on the front ear shell 4 to accommodate the speaker 5, the inner shell 1 and the noise reduction component 2 in a closed accommodating cavity 200.

[0055] In summary, compared with the prior art, the earphone 100 has at least the following beneficial effects: the earphone 100 opens a main sound outlet hole 121 on the inner shell 1, so that the inner wall of the inner shell 1 and the speaker 5 together form a sound cavity, and ensures that the main sound outlet hole 121 is connected to the sound cavity to form a main sound outlet channel 300; opens a sound pickup hole 122 on the inner shell 1, opens a groove 11 on the outer wall of the inner shell 1, and ensures that the sound pickup hole 122 is connected to the groove 11 to form a sound pickup channel 400, thereby, the main sound outlet channel 300 and the sound pickup channel 400 are connected by the outer shell. 400 are separated, and the speaker 5 and the microphone 21 are respectively arranged on the inner wall and the outer wall of the inner shell 1, so that the microphone 21 can pick up the ambient sound in the ear canal alone without being affected by the sound emitted by the speaker 5. At the same time, the microphone 21 can be set at a suitable position on the outer wall of the inner shell 1 without being restricted by the mold, molding, space, etc. In short, the microphone 21 in the earphone 100 has a good sound pickup effect, and then a good noise reduction effect, and the layout of the microphone 21 can be more flexible and reasonable, which is conducive to improving the overall quality and sound effect of the earphone 100.

[0056] In order to make those skilled in the art better understand the present invention, Figures 1 to 10 , clearly and completely describe the technical solutions in the embodiments of the present invention.

[0057] In some embodiments, Figure 5 , Fig. 9 and Fig.10 As shown, in order to simplify the structure and take into account ergonomics to improve the comfort of the user's ears, a boss 12 is convexly provided on the inner shell 1, wherein the boss 12 is provided with a main sound outlet 121 and a sound pickup hole 122. When the assembly 3 is set on the inner wall of the pre-ear shell 4, the boss 12 of the inner shell 1 is inserted into the avoidance hole 41 of the pre-ear shell 4. It can be understood that the main sound outlet 121 and the sound pickup hole 122 are integrated on the boss 12 and communicate with the ear canal through the same avoidance hole 41.

[0058] In some embodiments, Figure 5 , Fig. 9 and Fig.10 As shown, in order to simplify the structure and realize the structure in which the main sound output channel 300 and the sound pickup channel 400 are separated, the groove 11 is formed by the outer wall of the inner shell 1 being concave. Fig. 9 As shown, the wall of the boss 12 and the bottom of the groove 11 are provided with connecting holes 123. Figure 3 As shown, the sound pickup hole 122 is connected to the connecting hole 123 ( Figure 3 The connecting hole 123 (not shown) is communicated with the groove 11, thereby forming a sound pickup channel 400.

[0059] It can be understood that, on the one hand, the sound pickup channel 400 is formed separately on the inner shell 1 and has nothing to do with the speaker 5, etc. Therefore, the position, size, etc. of the sound pickup channel 400 may not be affected by molds, molding, space, etc. Correspondingly, a groove 11 may be formed at a suitable position on the outer wall of the inner shell 1 according to actual needs to place the microphone 21, and the microphone 21 is connected to the sound pickup channel 400 from the bottom of the groove 11, which is conducive to the reasonable layout of the microphone 21. On the other hand, because the sound pickup channel 400 is formed on the side of the inner shell 1, it can be separated from the main sound output channel 300 surrounded by the inner wall of the inner shell 1 and the speaker 5 through the shell wall of the inner shell 1, which is conducive to improving the sound pickup effect of the microphone 21.

[0060] In some embodiments, Figure 8 As shown, in order to install the microphone 21, the noise reduction component 2 also includes a mounting bracket 22, wherein the mounting bracket 22 includes a main bracket 221 and a mounting frame 222.

The mounting bracket 222 is located in the groove 11 and supports the microphone 21 .

[0061] In this embodiment, if Figure 3 and Figure 8As shown, in order to enable the microphone 21 to smoothly pick up sound, a first through hole 2221 is provided on the mounting frame 222 of the noise reduction component 2 at a position corresponding to the sound pickup through hole 211 of the microphone 21, and the first through hole 2221 communicates with the sound pickup through hole 211 and the sound pickup channel 400. It can be understood that the ambient sound in the user's ear canal can be picked up by the microphone 21 through the sound pickup channel 400, the first through hole 2221 and the sound pickup through hole 211 in sequence.

[0062] In some embodiments, Figure 3 As shown, in order to make the microphone 21 pick up sound more smoothly, the size of the first through hole 2221 of the mounting frame 222 is greater than or equal to the size of the sound pickup through hole 211 of the microphone 21. Preferably, the center line of the first through hole 2221 and the center line of the sound pickup through hole 211 are on the same straight line.

[0063] In some embodiments, Fig. 9 As shown, in order to simplify the structure and ensure the stable installation between the inner shell 1 and the noise reduction component 2, a contoured groove 13 is also provided on the outer wall of the inner shell 1. Figure 5 and Figure 6 As shown, a main bracket 221 is disposed in the profiling groove 13 , and the profiling groove 13 is adapted to the main bracket 221 .

[0064] In some embodiments, Figure 2 and Figure 3 As shown, in order to realize the electrical connection and control of each electronic device in the earphone 100, the rear ear shell component 6 includes an electronic control device 61; Figure 3 , Figure 7 and Figure 8 As shown, the mounting bracket 22 of the noise reduction component 2 also includes an electrical connection frame 223 and a connecting member 224, wherein the electrical connection frame 223 is connected to the main bracket 221 through the connecting member 224, and the electrical connection frame 223 is located on the inner side of the speaker 5 and is electrically connected to the electronic control device 61, so as to realize the electrical connection between the microphone 21 and the electronic control device 61.

[0065] Specifically in this embodiment, Figure 8 As shown, the main bracket 221, the mounting bracket 222, the connecting member 224 and the electrical connecting bracket 223 are integrally formed. Preferably, the mounting bracket 22 is a flexible circuit board. It can be understood that the microphone 21 is attached to the outer wall of the inner shell 1 through the flexible circuit board, and is electrically connected to the electronic control device 61 of the rear ear shell component 6 through the flexible circuit board, so as to achieve the sound pickup and noise reduction operation.

[0066] In some embodiments, to improve the sound quality of the earphone 100, Figure 5 , Fig. 9 and Fig.10 As shown, a secondary sound outlet 14 is also provided on the outer wall of the inner shell 1; Figure 5 As shown, the main support 221 of the noise reduction component 2 has an escape space 2211, and the pre-ear shell 4 is also provided with a sound outlet 42. Figure 4 As shown, the secondary sound outlet 14 of the inner shell 1 is connected with the avoidance space 2211 of the noise reduction component 2 and the sound outlet 42 of the pre-ear shell 4 to form a secondary sound outlet channel 500; wherein, the secondary sound outlet channel 500 is connected with the main sound outlet channel 300 and is separated from the sound pickup channel 400. That is, the earphone 100 has two sound outlet channels, the main sound outlet channel 300 and the secondary sound outlet channel 500. Part of the sound emitted by the speaker 5 can enter the ear canal from the main sound outlet channel 300, and the other part can enter the ear canal from the secondary sound outlet channel 500, which is conducive to forming a better sound effect in the ear canal.

[0067] Preferably, in this embodiment, in order to make the sound output smoother, Figure 4 As shown, the size of the sound outlet 42 is larger than or equal to the secondary sound outlet 14. In addition, the size of the avoidance space 2211 is larger than the sound outlet 42.
