[0027] With the development of technology and the improvement of living standards, people begin to enjoy life and music. As a convenient portable music playback device that can be used immediately, headphones have been integrated into people's daily lives. More and more people are used to wearing headphones to listen to music during idle time such as on the way to and from work, enjoying their own music time, and the requirements for the sound quality of headphones are also getting higher and higher. The essence of headphones is a small audio system placed in the ear. There is a speaker inside the headphones. Through the vibration inside the speaker, the surrounding air resonates, thus generating sound. When the air inside the headphones resonates, an air current will be generated. The air pressure inside the headphones will increase due to the flow of the air current, thus increasing the resistance to the vibration inside the speaker and resulting in the deterioration of the headphone sound quality. Therefore, in order to maintain the air pressure balance in the front cavity of the headphones and ensure the sound effect of the headphones, a pressure relief hole 40 communicating with the sound outlet channel is usually provided on the headphones to adjust the air pressure inside the headphones. In the prior art, during the manufacturing process using a mold, the size of the pressure relief hole 40 is often large, and it is very easy to cause the phenomenon of air leakage in the front sound cavity during pressure relief, and better sound quality cannot be obtained. The large size of the pressure relief hole 40 will also affect the appearance of the product; at the same time, due to the large size of the pressure relief hole 40, the waterproof performance of the headphones is weak. When water directly flushes against the pressure relief hole 40, the water easily enters the cavity, causing the waterproof function to fail, thus affecting the normal use of the headphones. At the same time, the poor waterproof performance is not suitable for the needs of waterproofing and sweating prevention during sports, running, etc., and the use scenarios of the headphones are limited.

[0028] Reference Figure 1 、 Figure 2 andFigure 3 , to solve the above problems, an embodiment of the present application provides a waterproof earphone 10, including: a first housing part 20, provided with a first accommodation cavity 21 and a sound outlet hole 22 communicating with the first accommodation cavity 21, and a speaker 210 is provided in the first accommodation cavity 21; a second housing part 30, the second housing part 30 communicates with the first housing part 20, and the sound outlet hole 22 is located on a side of the first housing part 20 away from the second housing part 30; the second housing part 30 is provided with a second accommodation cavity 31, and the second accommodation cavity 31 communicates with the first accommodation cavity 21; a control component 311 is provided in the second accommodation cavity 31, and the control component 311 is electrically connected to the speaker 210 to control the speaker 210 to emit sound; a pressure relief hole 40, the pressure relief hole 40 communicates with the first accommodation cavity 21 through a bent track-shaped channel 50, and the pressure relief hole 40 is provided between the first housing part 20 and the second housing part 30.

[0029] In this waterproof earphone 10, it includes a first housing part 20, a second housing part 30 and a pressure relief hole 40. The first housing part 20 and the second housing part 30 form the housing of the waterproof earphone 10, which has the function of protecting the internal structure of the waterproof earphone 10. The first housing part 20 and the second housing part 30 can be made of waterproof materials, so that the housing of the waterproof earphone 10 can effectively prevent water. The pressure relief hole 40 is used to adjust the air pressure inside the waterproof earphone 10. The first housing part 20 is provided with a first accommodation cavity. A speaker 210 is provided in the first accommodation cavity 21. The first accommodation cavity 21 serves to accommodate other structures. The sound outlet hole 22 is connected to the first accommodation cavity 21. The sound emitted by the speaker 210 provided in the first accommodation cavity 21 can be emitted from the waterproof earphone 10 through the sound outlet hole 22. When the user uses the waterproof earphone 10, the sound outlet hole 22 is placed in the ear canal of the user's ear, so that the user can hear the sound in the waterproof earphone 10. The second housing part 30 communicates with the first housing part 20, making the inside of the waterproof earphone 10 communicate. The sound outlet hole 22 is located on the side of the first housing part 20 away from the second housing part 30. When the user uses the waterproof earphone 10, the first housing part 20 is close to the ear canal opening of the user's ear, and the second housing part 30 is located outside the user's ear relative to the first housing part 20. The second housing part 30 is provided with a second accommodation cavity 31. The second accommodation cavity 31 serves to accommodate. The second accommodation cavity 31 communicates with the first accommodation cavity 21. A control component 311 is provided in the second accommodation cavity 31. The control component 311 can control the speaker 210 to emit sound. The control component 311 is electrically connected to the speaker 210. The pressure relief hole 40 communicates with the first accommodation cavity 21 through a track-shaped channel 50 in a bent shape. The pressure relief hole 40 has the function of relieving pressure on the waterproof earphone 10. The pressure relief hole 40 is provided between the first housing part 20 and the second housing part 30. The position of the pressure relief hole 40 is between the first housing part 20 and the second housing part 30 and is not easily found. Compared with the prior art, it can improve the aesthetics of the waterproof earphone 10. At the same time, the pressure relief hole 40 is set in a hole shape, and the hole structure is small, which can make the waterproof earphone 10 have better waterproof performance. A reliable waterproof structure can make the waterproof earphone 10 not affected by environmental temperature changes, and at the same time can block the direct impact of water pressure. It is also suitable for the needs of waterproofing and sweating during sports, running, etc., and can increase the usage scenarios of the waterproof earphone 10.When the user uses the waterproof earphone 10, the control component 311 in the second accommodating cavity 31 controls the speaker 210 to emit sound. When the speaker 210 emits sound, the air inside the earphone resonates to generate an air flow. The air pressure inside the earphone increases due to the flow of the air flow, thereby increasing the resistance to vibration inside the speaker. The pressure relief hole 40 is communicated with the first accommodating cavity 21 through the bent track-shaped channel 50. The pressure relief hole 40 relieves pressure to adjust the air pressure inside the earphone, thereby ensuring the normal use of the waterproof earphone 10. The track-shaped channel 50 has a waterproof function, which can isolate the inside of the first accommodating groove and the second accommodating groove of the waterproof earphone 10 from the pressure relief hole 40 to a certain extent. The bent track-shaped channel 50 can also prevent dust from easily entering the first accommodating cavity 21, which is beneficial to protecting the internal components of the earphone. The track-shaped channel 50 between the pressure relief hole 40 and the second accommodating groove can increase the waterproof performance of the earphone to a certain extent, can block the direct impact of water pressure, and thus improve the waterproof performance of the waterproof earphone 10.

[0030] Refer to Figure 1 and Figure 2, the first housing part 20 and the second housing part 30 of the waterproof earphone 10 are detachably connected, which is convenient for the maintenance of the earphone. When the earphone needs to be repaired, compared with the integrated earphone, the interior of the earphone can be overhauled by disassembling the first housing part 20 and the second housing part 30. A track-type channel 50 is formed by covering between the first housing part 20 and the second housing part 30. The track-type channel 50 is arranged between the first accommodating cavity 21 and the second accommodating cavity 31. The end of the track-type channel 50 is a pressure relief hole 40, which can enable the gas inside the first accommodating cavity 21 and the second accommodating cavity 31 to be discharged from the pressure relief hole 40, thereby adjusting the air pressure inside the earphone. The shape of the track-type channel 50 is bent, and the structural feature of the bent shape can play a certain role in waterproofing. Specifically, a bent first pressure relief groove 23 is formed on the outer surface of the first housing part 20. The end of the first pressure relief groove 23 is communicated with the first accommodating cavity 21. A second pressure relief groove 32 is formed on the outer surface of the second housing part 30. The first pressure relief groove 23 and the second pressure relief groove 32 are covered with each other to form the track-type channel 50. The end of the first pressure relief groove 23 is communicated with the first accommodating cavity 21. The first pressure relief groove 23 and the second pressure relief groove 32 together form the track-type channel 50. At the same time, the first pressure relief groove 23 and the second pressure relief groove 32 are respectively communicated with the first accommodating groove, and the first pressure relief groove 23 and the second pressure relief groove 32 are respectively communicated with the second accommodating groove, which can enable the gas inside the waterproof earphone 10 to be discharged outside the earphone through the track-type channel 50. The end of the track-type channel 50 at the position of the pressure relief hole 40 is connected to the outside. For example, when there is water vapor in the environment, the pressure relief hole 40 can play a waterproof role due to its small hole structure; the bent shape can prevent the water vapor from directly entering the first accommodating cavity 21 and the second accommodating cavity 31, thereby improving the waterproof performance of the waterproof earphone 10. At the same time, the track-type channel 50 with a bent shape can also prevent dust from easily entering the first accommodating cavity 21, which is beneficial to protecting the internal components of the earphone, thereby improving the service life of the earphone.

[0031] Refer to Figure 1 and Figure 3The first shell part 20 and the second shell part 30 constitute the shell of the waterproof earphone 10, which has the function of protecting the internal structure of the waterproof earphone 10. The first shell part 20 and the second shell part 30 can be made of waterproof material, so that the shell of the waterproof earphone 10 can be effectively waterproof. The earphone can be made of plastic material. Plastic is the most common material in earphone manufacturing. It has moderate density and strength, and is highly plastic. Various shapes of earphones can be designed using plastic. Since the earphone will inevitably rub against clothes, hair, etc. during use, the method of decorating the earphone by spraying paint on plastic is difficult to last and is easy to cause the earphone to crack. It is more common to use natural color plastic high gloss demoulding. In some embodiments, the earphone can also be made of metal material. At present, aluminum alloy is more commonly used for metal material. Metal material is suitable for fine processing and also suitable for small batch production. In addition to the excellent natural color texture, metal can also be colored by oxidation, electroplating and other processes, or processed by sandblasting, wire drawing and other processes to enhance the texture of the earphone.

[0032] refer to Figure 1 The second shell portion 30 is connected to an ear hook 60, and the ear hook 60 is bent and extended around the first shell portion 20. The ear hook 60 can play a supporting role. When the user uses the earphone, the ear hook 60 can be hung on the user's auricle to fix the earphone on the user's ear. In some embodiments, the ear hook 60 can be in the shape of an auricle, and the ear hook 60 is usually arranged in an arc shape. In some embodiments, the ear hook 60 can also be customized according to the needs of the user to improve the comfort of the user wearing the earphone. When the user wears the earphone, the ear hook 60 is hung on the auricle, and the sound outlet 22 of the first shell portion 20 is placed in the ear canal of the user. In some embodiments, the pressure relief hole 40 faces the side where the ear hook 60 is connected to the second shell portion 30, which can improve the aesthetics of the earphone. Specifically, the pressure relief hole 40 is facing the side where the ear hook 60 is connected to the second shell part 30. When the user wears the earphone, the pressure relief hole 40 faces the inside of the user, making the pressure relief hole 40 difficult to be seen, thereby improving the aesthetics of the earphone when worn. At the same time, it can also prevent external water from impacting the pressure relief hole 40, and can prevent the waterproof earphone 10 from getting water in, thereby improving the waterproof performance of the waterproof earphone 10.

[0033] See also Figure 1 , Figure 2 and Figure 3, the first housing part 20 and the second housing part 30 of the earphone together constitute the housing structure of the earphone. Among them, in some embodiments, the radial dimension of the second housing part 30 is larger than that of the first housing part 20, enabling the second housing part 30 to play a role in shielding the first housing part 20 in a certain direction. At the same time, the ear hook 60 is connected to the radial edge of the second housing part 30. Relative to the first housing part 20, the second housing part 30 is located on the side away from the ear. Since the pressure relief hole 40 is provided between the first housing part 20 and the second housing part 30, when the radial dimension of the second housing part 30 is larger than that of the first housing part 20, the second housing part 30 can play a certain role in shielding the pressure relief hole 40, which can improve the aesthetics of the waterproof earphone 10. At the same time, it can also prevent the water from the outside from impacting the pressure relief hole 40, preventing the waterproof earphone 10 from getting water in, and thus improving the waterproof performance of the waterproof earphone 10. In some embodiments, to improve the waterproof performance of the waterproof earphone 10, a waterproof member 24 can be provided in the first accommodation cavity 21. The waterproof member 24 can prevent the water that accidentally enters the track-shaped channel 50 from the pressure relief hole 40 from entering the first accommodation cavity 21. Specifically, the waterproof member 24 covers the connection between the track-shaped channel 50 and the first accommodation cavity 21, creating a layer of isolation and shielding between the track-shaped channel 50 and the first accommodation cavity 21. At the same time, the waterproof member 24 does not affect the normal sound output of the waterproof earphone 10. While ensuring the normal sound output of the waterproof earphone 10, it effectively prevents water from entering the first accommodation cavity 21 inside the earphone, thereby improving the waterproof performance of the waterproof earphone 10. In some embodiments, the earphone is also provided with a button 70 through which the user can adjust the earphone. In some embodiments, a battery 25 is also provided in the first accommodation cavity 21. The battery 25 is located on the side of the speaker 210 away from the sound outlet hole 22, and the speaker 210 is close to the sound outlet hole 22. The battery 25 can provide power for the speaker 210. Specifically, the earphone can use a rechargeable lithium battery, such as a soft-pack lithium battery, a steel-shell cylindrical lithium battery, and a button lithium battery. Using the rechargeable lithium battery as the power source, when charging, the earphone needs to be placed in a charging case for charging. Placing the battery 25 inside the waterproof earphone 10 can achieve the functions of long-term battery life, stable power output, and good charging performance of the earphone.

[0034] Reference Figure 1 and Figure 2, on one side of the first housing part 20 away from the second housing part 30, a protruding earplug part 26 is formed. The periphery of the earplug part 26 can be arc-shaped, which is beneficial to improving the wearing comfort of the user. The volume of the earplug part 26 is small, and when the user wears the earphone, the earplug part 26 can be placed inside the ear. The sound outlet hole 22 is opened on the earplug part 26, and the sound of the waterproof earphone 10 can be emitted from the sound outlet hole 22, so that the user can hear the sound in the earphone. In order to improve the waterproof performance of the earphone, a waterproof net 220 can be provided at the sound outlet hole 22, and the waterproof net 220 can prevent the water from the outside from entering the earphone. In this waterproof earphone 10, the main function of the sound outlet hole 22 is to emit sound, and the function of the pressure relief hole 40 is on the one hand to emit sound, and on the other hand to exhaust and relieve pressure for the earphone, so as to adjust the pressure inside the earphone and ensure the sound quality of the earphone when it emits sound. The cooperation between the two can ensure that the earphone emits sound normally and has good sound quality. The waterproof net 220 can prevent water from entering the first accommodating cavity 21 from the sound outlet hole 22. The bent shape of the track-shaped channel 50 can make there be a certain distance block between the pressure relief hole 40 and the first accommodating cavity 21 and the second accommodating cavity 31, which can prevent water from being directly washed into the earphone interior. At the same time, compared with the groove structure in the prior art, the hole-shaped structure of the pressure relief hole 40 is smaller. The small hole-shaped structure not only improves the aesthetics of the waterproof earphone 10, but also can greatly reduce the possibility of the earphone getting water. A waterproof member 24 is provided in the first accommodating cavity 21 and is arranged at the communication place between the track-shaped channel 50 and the first accommodating cavity 21, which can prevent the water passing through the track-shaped channel 50 from entering the first accommodating cavity 21, and also plays a waterproof role. The earphone protected by this solution has carried out waterproof protection in many aspects in terms of structure, and can effectively improve the waterproof performance of the earphone.

[0035] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0036] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
