[0040] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can also be made, which should be considered as the protection scope of the present application.
[0041] Reference Figure 1 And Figure 2 The earphone shell 10 provided by the present application includes a sound outlet shell 11 and a back cover 2; the sound outlet shell 11 has a sound cavity for placing a loudspeaker 13, and the near-ear side of the sound outlet shell 11 has a sound outlet hole 112 communicating with the sound cavity; the back cover 2 is installed on the back-ear side of the sound outlet shell 11, and the joint of the back cover 2 and the sound outlet shell 11 has a sound leakage hole 111 communicating with the sound cavity.
[0042] In the present embodiment, the sound leakage hole 111 is located at the joint of the sound outlet shell 11 and the back cover 2, and the sound leakage hole 111 arranged at the joint can improve the sound quality effect without affecting the overall aesthetics of the earphone shell 10 and having better appearance performance.
[0043] The sound outlet hole 112 is installed at one end of the sound outlet shell 11 away from the back cover 2, and when the sound outlet shell 11 is placed inside the auricle, the sound outlet hole 112 faces the inside of the auricle, which can better transmit the sound of the loudspeaker 13 into the ear.
[0044] Specifically, generally the loudspeaker 13 in the earphone shell 10 uses resonance principle to send sound waves into the air to produce sound, and the sound cavity in the earphone shell 10 is completely closed except the sound outlet hole 112, so that the vibration of the loudspeaker 13 also increases the pressure inside the earphone shell 10, which in turn hinders the vibration of the loudspeaker 13. The sound leakage hole 111 can make air flow in and out of the loudspeaker 13, not only preventing the accumulation of pressure in the sound cavity, but also allowing the loudspeaker 13 in the earphone shell 10 to move more freely, creating better sound quality and bass effect.
[0045] Notably, the sound leakage hole 111 can be located on the sound outlet shell 11 and close to the back cover 2, and when the sound outlet shell 11 and the back cover 2 are installed and connected, the sound leakage hole 111 is just located at the joint of the sound outlet shell 11 and the back cover 2. It can also be that the sound outlet shell 11 and the back cover 2 have an opening near the connection, and when the sound outlet shell 11 and the back cover 2 are installed and connected, the two openings combine into one sound leakage hole 111.
[0046] Further, referring to Figure 3 and Figure 4 , the sound outlet shell 11 is a stepped surface, the near-ear side is a high end surface, the back-ear side is a low end surface, the high end surface is provided with a hole at the joint with the low end surface, the hole has a radial opening and a horizontal opening, and after the back cover 2 is connected with the sound outlet shell 11, the end of the back cover 2 close to the near-ear side is parallel to the high end surface and covers the horizontal opening, and the radial opening of the hole forms the sound leakage hole 111.
[0047] In this embodiment, the sound leakage hole 111 is located on the high end surface of the sound outlet shell 11 and close to the low end surface, which ensures the structural strength of the sound outlet shell 11, and the sound leakage hole 111 is located at the joint of the back cover 2 and the sound outlet shell 11, which makes it more convenient and labor-saving to disassemble the earphone shell 10.
[0048] Specifically, one end of the sound leakage hole 111 is the back cover 2, and the other end is the sound outlet shell 11, and when disassembling the earphone shell 10, the back cover 2 and the sound outlet shell 11 can be directly separated from the sound leakage hole 111, the sound leakage hole 111 can be used as a disassembly hole, which greatly improves the convenience of disassembling the earphone shell 10.
[0049] Preferably, referring to Figure 5 , the sound outlet shell 11 has a clamping part 18, the back cover 2 has a clamping protrusion 22, and when the clamping protrusion 22 is inserted into the clamping part 18, the sound leakage hole 111 is just located at the joint of the sound outlet shell 11 and the back cover 2.
[0050] In this embodiment, the clamping part 18 is located at the top end of the low end surface of the sound outlet shell 11 and close to one end of the back cover 2, and the clamping protrusion 22 is located at one end of the back cover 2 close to the sound outlet shell 11, which makes it easier to clamp and connect the clamping part 18 and the clamping protrusion 22, and makes the installation of the sound outlet shell 11 and the back cover 2 more convenient and convenient, without affecting the overall appearance of the earphone shell 10, and has excellent visual aesthetics.
[0051] It is worth noting that the clamping part 18 can also be located on the back cover 2, and the corresponding clamping protrusion 22 is located on the sound outlet shell 11, as long as the sound outlet shell 11 can be clamped and installed with the back cover 2. The sound outlet shell 11 and the back cover 2 can also be fixed by bolts or other fixing members, as long as the sound outlet shell 11 and the back cover 2 are installed, the end of the back cover 2 close to the near-ear side is parallel to the high-end surface and covers the horizontal opening, and the sound leakage hole 111 is located at the joint. Even the sound outlet shell 11 and the back cover 2 can be unique as a whole.
[0052] Further, with reference to Figure 10 And Figure 11 Further, the elastic middle frame 4 is bent to form a clamping space, and the first end portion 41 and the second end portion 42 of the elastic middle frame 4 have an opening communicating with the clamping space, and the sound outlet shell 11 is installed on the side of the first end portion 41 away from the opening.
[0053] In this embodiment, the earphone shell 10 is a clip-on earphone, the first end portion 41 and the second end portion 42 of the elastic middle frame 4 form a clamping space, which can better clamp the earphone shell 10 on the auricle and is not easy to fall off. Expanding the first end portion 41 and the second end portion 42 can make the opening of the clamping space larger, so that the earphone shell 10 can be taken off from the auricle or worn on the auricle; when wearing the earphone shell 10, the first end portion 41 of the elastic middle frame 4 is located inside the auricle, and the second end portion 42 is located on the back of the auricle.
[0054] Specifically, when wearing the earphone shell 10, press the middle part of the elastic middle frame 4 or one finger against the first end portion 41, and one finger against the second end portion 42, expand the clamping space of the elastic middle frame 4 to make the opening larger, and then put the earphone shell 10 from the opening to the auricle, while the elastic middle frame 4 has a certain elasticity, and the first end portion 41 and the second end portion 42 of the elastic middle frame 4 are loosened, the opening on one side of the clamping space will become smaller and return to the original size, and at the same time the clamping space formed by the first end portion 41 and the second end portion 42 of the elastic middle frame 4 also returns to the original type and clamps the auricle, at this time the sound outlet shell 11 connected with the first end portion 41 is clamped on the front of the auricle, and the second end portion 42 clamps the back of the auricle, fixing the earphone shell 10 on the auricle.
[0055] It is worth noting that the elastic middle frame 4 should be in line with the relevant size of the auricle, simple and beautiful, while also meeting the requirements of most people for the comfort of wearing earphones. Among them, the length of the opening of the elastic middle frame 4 and the width of the clamping space will affect the comfort and experience of wearing earphones. In order to adapt to the ear size of most people and meet the requirements of most people for wearing comfort and tightness, the length of the opening is between 0-7.5mm, and the width of the clamping space is between 2-15mm.
[0056] In a variant embodiment, the earphone shell 10 can also be over-ear type, one end of the sound outlet shell 11 extends outward and forms an over-ear middle frame, the over-ear middle frame has an over-ear space, which is consistent with the shape of the root of the auricle, and can fix the earphone shell 10 on the auricle. When wearing the earphone shell 10, first place the sound outlet shell 11 inside the auricle, then make the over-ear middle frame close to the auricle and rotate around the auricle, so that the over-ear middle frame is in line with the auricle, and the root of the auricle is placed in the over-ear space. It can also be that the over-ear middle frame is in line with the auricle first, and then the sound outlet shell 11 is placed inside the auricle.
[0057] Further, when the elastic middle frame 4 is clamped on the auricle of the wearer, and the sound outlet shell 11 is located on the front side of the auricle, the sound leakage hole 111 is directed towards the earlobe of the wearer.
[0058] In this embodiment, when wearing the earphone shell 10, the sound leakage hole 111 is just located at the bottom of the sound outlet shell 11 and is directed towards the earlobe of the wearer, which can have better waterproof effect.
[0059] Specifically, when wearing the earphone shell 10, the sound outlet shell 11 is placed inside the auricle, and the first end portion 41 of the elastic middle frame 4 is clamped inside the auricle, and the second end portion 42 is clamped on the back of the auricle. At this time, the entire earphone shell 10 can be placed relatively horizontally or relatively inclined, and the sound leakage hole 111 is always located at the bottom of the earphone shell 10 and is directed towards the earlobe of the wearer, i.e. downward. At this time, even in rainy days, the rain falling from the top or the side is not easy to enter the sound leakage hole 111, and the rain entering the sound leakage hole 111 will automatically fall due to gravity, so the sound leakage hole 111 naturally has better waterproof effect when wearing the earphone shell 10.
[0060] Further, it also includes a waterproof and breathable film 17, which is located at the joint of the rear cover 2 and the sound outlet shell 11, used to cover the sound leakage hole 111.
[0061] In this embodiment, the waterproof air-permeable film 17 is arranged in the sound leakage hole 111, which can further improve the waterproof effect of the sound leakage hole 111. In the case of extreme water inflow, the waterproof air-permeable film 17 can provide waterproof protection for the sound leakage hole 111 for a certain period of time, thereby protecting the loudspeaker 13 in the sound outlet shell 11.
[0062] It is worth noting that the waterproof air-permeable film 17 is preferably arranged at the end of the sound leakage hole 111 close to the sound cavity, which serves as the last line of defense. If it is arranged at the outermost end of the sound leakage hole 111, the daily moisture will repeatedly erode the waterproof air-permeable film 17, which greatly reduces the service life of the waterproof air-permeable film 17. Meanwhile, the sound leakage hole 111 is also provided with a tuning net and tuning cotton, which can better and more accurately adjust the sound.
[0063] Further, the earphone shell 10 further comprises a battery shell 3 having a battery cavity for mounting a battery 35, the battery shell 3 is mounted on the second end portion 42 of the elastic middle frame 4 and is located on the side of the second end portion 42 away from the opening; and the two ends of the rear cover 2 are respectively mounted on the sound outlet shell 11 and the battery shell 3.
[0064] In this embodiment, one end of the rear cover 2 is connected to one end of the sound outlet shell 11, and one end of the sound outlet shell 11 is connected to the battery shell 3. The middle part of the rear cover 2 is connected to the elastic middle frame 4, and the entire earphone shell 10 presents a C shape. When the earphone shell 10 is worn, the elastic middle frame 4 clamps the auricle, the sound outlet shell 11 clamps the inside of the auricle, and the battery shell 3 clamps the back of the auricle. The sound outlet shell 11 and the battery shell 3 are respectively located at the two ends of the auricle. In this way, the weight balance of the earphone shell 10 can be controlled by controlling the weights of the sound outlet shell 11 and the battery shell 3, so that the earphone shell 10 can be better clamped on the auricle, and the wearing comfort of the earphone shell 10 is greatly improved.
[0065] Further, the sound outlet shell 11 further comprises a sound pickup hole 113 and a noise reduction hole 114, the sound pickup hole 113 and the noise reduction hole 114 are in communication with the sound cavity, the sound pickup hole 113, the noise reduction hole 114 and the sound leakage hole 111 are on the same straight line, and the straight line is parallel to the middle line of the elastic middle frame 4 passing through the opening.
[0066] In this embodiment, the sound pickup hole 113, the noise reduction hole 114 and the sound leakage hole 111 are on the same horizontal plane and are parallel to the middle line of the elastic middle frame 4 passing through the opening, which can make the earphone have better sound output effect.
[0067] It is worth noting that the position of the sound pickup hole 113 corresponds to the position of the sound pickup microphone 14. That is, the sound pickup hole 113 is located on the same side of the sound outlet shell 11 as the sound leakage hole 111, and is in communication with the sound pickup microphone 14. The position of the noise reduction hole 114 corresponds to the position of the noise reduction microphone 15. That is, the noise reduction hole 114 is located on the side of the sound outlet shell 11 opposite the sound pickup hole 113, and is in communication with the noise reduction microphone 15. The sound pickup hole 113 and the noise reduction hole 114 can better collect external sounds for the sound pickup microphone 14 and the noise reduction microphone 15, thereby improving the interaction ability and use experience of the earphone.
[0068] Further, the magnetic elements include a first magnetic element 16 and a second magnetic element 37, the first magnetic element 16 is installed on the first end portion 41 of the elastic middle frame 4, the second magnetic element 37 is installed on the second end portion 42 of the elastic middle frame 4, and the first magnetic element 16 and the second magnetic element 37 are oppositely arranged; the first magnetic element 16 and the second magnetic element 37 are matched and arranged, and can attract each other, for reducing the distance between the first end portion 41 and the second end portion 42.
[0069] In the embodiment, the first magnetic element 16 and the second magnetic element 37 can attract each other, so that the opening of the clamping space at one end between the first end portion 41 and the second end portion 42 of the elastic middle frame 4 is kept within a preset length without external pressure, thereby improving the wearing comfort and stability of the earphone shell 10. In particular, after wearing the earphone shell 10, the interaction force of the first magnetic element 16 and the second magnetic element 37 can reduce the opening which is enlarged by pressing, so that the earphone shell 10 can be firmly clamped on the auricle, thereby greatly improving the anti-drop performance of the earphone shell 10 and the convenience of wearing the earphone shell 10.
[0070] Specifically, when wearing the earphone shell 10, the elastic middle frame 4 is pressed, the middle portion of the elastic middle frame 4 can be deformed under pressure, the elastic middle frame 4 forms a larger clamping space, and the opening length between the first end portion 41 and the second end portion 42 is also larger, and then the auricle is clamped in the clamping space, at this time the sound outlet shell 11 is placed in the auricle, and the battery shell 3 is placed on the back of the auricle, and when the elastic middle frame 4 is loosened, the first magnetic element 16 and the second magnetic element 37 attract each other to reduce the size of the opening, and the earphone shell 10 is clamped on the auricle, which is simple and convenient to wear.
[0071] It is worth noting that the first magnetic element 16 and the second magnetic element 37 are a magnetic matched combination, which can be a magnet and iron, or a magnet and a magnet, etc.
