[0027] With the continuous development of headphone technology, headphones with waterproof function have received widespread attention. Waterproof headphones are headphones designed specifically for sports or humid environments. They can effectively prevent water intrusion and ensure that the headphones can still work normally in humid environments. Waterproof headphones are mainly divided into two types: wired and wireless. Wired waterproof headphones connect to devices via cables, usually have a higher waterproof level, and are suitable for underwater use. Wireless waterproof headphones usually use Bluetooth technology to connect devices, without the need for cables, which is more convenient. This application can be applied to wireless headphones as well as wired headphones.

[0028] An embodiment of the present application provides an earphone structure that improves the waterproof performance of the earphone by optimizing the structure of the rear cavity hole.

[0029] Below, refer to Figures 1 to 5 Some embodiments of the present application are described in detail.

[0030] Figure 1 A schematic diagram of a three-dimensional structure of an earphone structure provided in some embodiments of the present application from one perspective; Figure 2 A cross-sectional view of an earphone structure provided for some embodiments of the present application;

[0031] Figure 3 A schematic diagram of the structure of the earphone provided in some embodiments of the present application without the cover; Figure 4 Another cross-sectional view of an earphone structure provided for some embodiments of the present application; Figure 5 A schematic diagram of the three-dimensional structure of the earphone structure provided in some embodiments of the present application from another perspective.

[0032] The first aspect of the present application provides an earphone structure, such as Figures 1 to 4As shown, the earphone main body shell includes a shell 10 and a shell cover 12, the shell 10 and the shell cover 12 cover each other and form a cavity, in which a sound unit 13 is provided, and the sound unit 13 divides the cavity into a front cavity 103 and a rear cavity 104, wherein the shell 10 is formed with a rear cavity hole 11, and the rear cavity hole 11 is composed of a first channel 111 and a second channel 112 that are interconnected, one end of the first channel 111 forms a first opening on the outer surface of the shell 10, and the other end is connected to the second channel 112, and the end of the second channel 112 away from the first channel 111 is connected to the rear cavity 104, and the extension direction of the first channel 111 intersects with the extension direction of the second channel 112, wherein the extension direction of the first channel 111 is from the opening to the interior, and the extension direction of the second channel 112 is from the direction connected with the first channel to the direction connected with the inner cavity.

[0033] The extension direction of the first channel 111 also represents the flow direction of the first channel 111, i.e., the direction from one end opening of the first channel 111 along the channel to the other end opening. The extension direction of the second channel 112 also represents the flow direction of the second channel 112, i.e., the direction from one end opening of the first channel 111 along the channel to the other end opening. The extension direction of the first channel 111 intersects with the extension direction of the second channel 112, i.e., the flow direction of the first channel 111 and the flow direction of the second channel 112 intersect, resulting in a curved flow direction of the rear cavity 11, including the first channel 111 and the second channel 112.

[0034] Exemplarily, the sound-emitting unit 13 includes a speaker. When the speaker produces sound through vibration, the vibration of the speaker will cause the air pressure in the rear cavity 104 to fluctuate. Under the excitation of the speaker vibration, the air in the rear cavity 104 will move from the surface of the speaker located in the rear cavity 104 to the rear cavity hole 11 and discharge from the rear cavity hole 11.

[0035] A rear cavity hole 11 is formed on the shell 10, and the rear cavity hole 111 includes a first channel 111 and a second channel 112 that are connected to each other. One end of the first channel 111 is open to the outer surface of the shell 10, and the other end is connected to the second channel 112. The end of the second channel 112 away from the first channel 111 is open and connected to the rear cavity 104, ensuring the circulation of airflow inside and outside the shell 10, thereby adjusting the balance of air pressure inside and outside the earphone structure and improving sound quality.

[0036] Moreover, the extension direction of the first channel intersects with the extension direction of the second channel, that is, the flow direction of the rear cavity hole is bent. The liquid entering the rear cavity hole needs to turn when passing through the first channel. The rear cavity hole hinders the flow of the liquid, making it easy for the liquid to adhere to the inner wall of the first channel, thereby reducing the possibility of liquid entering the rear cavity and reducing the chance of damage to the earphone structure.

[0037] In the earphone structure provided in the embodiment of the present application, the inner surface of the first channel 111 includes an inner bottom surface 121 opposite to the first opening in the extension direction of the first channel and an inner side surface 122 surrounding the inner bottom surface 121, and the second channel forms a second opening on the inner side surface 122, and there is a distance between the second opening and the inner bottom surface 121.

[0038] Therefore, most of the liquid entering the first channel 111 from the first opening will flow toward the inner bottom surface under the action of inertia. After flowing to the inner bottom surface 121, the liquid will easily gather in the area between the inner bottom surface 121 and the second opening under the blocking effect of the inner bottom surface 121, that is, the area between the inner bottom surface 121 and the second opening becomes a water storage area, further reducing the probability of liquid entering the rear cavity.

[0039] In the earphone structure provided by the embodiment of the present application, the second channel 112 is provided with a waterproof and breathable membrane 14.

[0040] The waterproof, breathable membrane 14 has extremely fine micropores, preventing even tiny water molecules from passing through them, thus achieving a waterproof effect. While waterproof, the membrane 14 also allows for ample ventilation, facilitating heat dissipation within the earphone structure and regulating internal and external pressures. The membrane's microporous structure also ensures sound transmission, preventing distortion.

[0041] In the earphone structure provided by the embodiment of the present application, the waterproof breathable membrane 14 covers the opening of the second channel 112 away from the first channel 111 , and a protective plate 120 is formed in the rear cavity 104 , which surrounds the outer periphery of the waterproof breathable membrane 14 .

[0042] The provision of the guard plate 120 enhances the protection of the waterproof breathable membrane 14 and reduces the probability of the waterproof breathable membrane 14 falling off, thereby further improving the waterproof effect. In addition, the inner wall of the guard plate 120 can also be used to adhere to liquid to a certain extent, reducing the probability of liquid contacting the sound unit.

[0043] In the earphone structure provided in the embodiment of the present application, the waterproof and breathable membrane 14 is made of a polymer material, and the polymer material includes expanded polytetrafluoroethylene.

[0044] Expanded polytetrafluoroethylene (ePTFE) is a common waterproof and breathable membrane material with excellent waterproof and breathable properties. This polymer film material offers properties such as dust and water resistance, breathability and pressure relief, microporous exhaust, and air pressure balance. Besides its excellent waterproof performance, it also ensures the breathability and acoustic performance of the headphones, providing users with a more comfortable and safe listening experience.

[0045] The earphone structure provided in the embodiment of the present application is as follows: Figure 5 As shown, a sound outlet 15 is formed on the outer surface of the housing 10 , and the sound outlet 15 is connected to the front cavity 103 .

[0046] In this way, the sound hole 15 and the rear cavity hole 11 are both provided on the shell 10, so that the positions of the two are relatively close. The sound hole 15 faces the human ear, so the rear cavity hole 11 is also relatively close to the ear. When worn, the rear cavity hole is not easy to be seen, and the appearance is beautiful. Moreover, the earphone structure is not easily directly impacted or invaded by external moisture, so that the earphone structure can better keep its internal dryness and normal operation when encountering water or humid environment.

[0047] The earphone structure provided in the embodiment of the present application is as follows: Figure 1 As shown, the outer surface of the shell 10 includes a bottom wall 101 and a side wall 102 surrounding the outer periphery of the bottom wall. The edge of the side wall 102 away from the bottom wall 101 is connected to the outer surface of the shell cover 12. The sound outlet 15 is formed in the bottom wall 101, and the rear cavity hole 11 is formed in the side wall 102.

[0048] The sound outlet 15 is located on the bottom wall 101, and the rear cavity 11 is located on the side wall 102. The rear cavity 11 is not easily visible, making the earphone structure less susceptible to direct impact or intrusion of external moisture. This effectively reduces the possibility of moisture entering the earphone through the rear cavity 11.

[0049] In the earphone structure provided by the embodiment of the present application, the shell 10 and the shell cover 12 are bonded to each other by an adhesive, and / or a sealing ring is provided between the shell 10 and the shell cover 12.

[0050] The adhesive tightly connects the housing 10 and the cover 12 together, forming a continuous seal. This effectively prevents moisture and other liquids from penetrating the earphone structure through the connection between the housing 10 and the cover 12. The adhesive strengthens the connection between the housing 10 and the cover 12, enhancing the overall structural strength. This helps prevent the connection between the housing 10 and the cover 12 from loosening or breaking in unexpected situations, such as drops or squeezing, further reducing the risk of liquid intrusion.

[0051] The sealing ring is installed at the connection between the housing 10 and the cover 12 to fill and close the small gap between the two objects, thereby forming an additional waterproof barrier. Even if the adhesive may have minor defects or deterioration in some cases, the sealing ring can still continue to play a waterproof role.

[0052] In the earphone structure provided in the embodiment of the present application, the area of ​​the second opening is smaller than the area of ​​the first opening.

[0053] Due to the reduced opening area, water may encounter greater resistance when passing through, helping to reduce the risk of water intrusion into the earphone structure. The smaller opening area of ​​the second channel 112 acts as a barrier. Even if external water accidentally enters the first channel, it will be less likely to enter due to the narrow second opening of the second channel 112, further reducing the chance of liquid intrusion.

[0054] A second aspect of the present application provides an earphone assembly, such as Figure 3 The earphone structure further includes an ear hook portion 20 and a power supply portion 30. One end of the ear hook portion 20 is connected to the housing 10 and extends along a curve for hooking onto the user's ear. One end of the ear hook portion 20 is connected to the housing 10 to form a connection end, and the other end of the ear hook portion 20 extends along a curve out of the outer surface of the housing 10 to form a structure capable of hooking onto the user's ear. For example, for ease of explanation, the side with the ear canal in the thickness direction of the ear is referred to as the front side of the ear, and the side without the ear canal in the thickness direction of the ear is referred to as the back side of the ear. When the earphone is worn, the connection end of the ear hook portion 20 is located at the front side of the user's ear and is wound around the space above the user's ear or between the user's auricle near the upper ear root and the user's head to the back side of the ear, thereby forming the ear hook portion 20 with a hook-shaped structure capable of hooking onto the user's ear. The hook-shaped structure can transfer the weight of the earphone to the user's ear and can limit the tendency of the earphone to detach from the ear through the force between the ear and the ear, so that the earphone can be reliably worn on the user's ear.

[0055] The power supply unit 30 is connected to the other end of the ear hook part 20 opposite to the end connected to the shell 10, that is, the power supply unit 30 and the shell 10 are respectively fixed at the opposite ends of the ear hook part 20. The power supply unit 30 is used to provide electrical energy to the electronic control component or sound unit in the shell 10 through the power supply structure in the ear hook part 20, so that the electronic control component drives the sound unit to vibrate to produce sound, thereby enabling the earphone structure to output sound.

[0056] The earphone structure provided in the embodiment of the present application has an earphone box with an earphone accommodating cavity, which is used to accommodate the earphone structure.

[0057] For example, the earphone box can prevent moisture, sweat or other liquids from entering the interior of the earphone, thereby protecting the electronic components and internal structure of the earphone from damage.

[0058] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
