[0057] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant accompanying drawings. Preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0058] As Figures 1 to 4 shown, in one embodiment, an earphone 10 is provided, which includes a main body 100, a first earplug 200 and a second earplug 300. The main body 100 includes a speaker 130 (shown in Figure 9 ). As Figure 1 and Figure 3 shown, the first earplug 200 is of a soft structure and can be assembled to the main body 100 and can be detached from the main body 100. When the first earplug 200 is assembled to the main body 100, the distance between the end of the first earplug 200 away from the main body 100 and the end face 121 of the main body 100 is L1 (shown in Figure 11 ). As Figure 2 and Figure 4 shown, the second earplug 300 is of a soft structure and can be assembled to the main body 100 and can be detached from the main body 100. When the second earplug 300 is assembled to the main body 100, the distance between the end of the second earplug 300 away from the main body 100 and the end face 121 of the main body 100 is L2 (shown in Figure 13 ), and L2 is greater than or equal to L1; when the second earplug 300 is installed on the main body 100, the inner cavity of the main body 100 can communicate with the outside, so that the earphone 10 has a deflating function. When the first earplug 200 is assembled to the main body 100, the earphone 10 is a semi-in-ear earphone. As Figure 5 shown, when the user wears the earphone 10, the first earplug 200 enters the ear canal 20, so that the depth of the earphone 10 entering the ear canal 20 is relatively shallow. When the second earplug 300 is assembled to the main body 100, the earphone 10 is an in-ear earphone. As Figure 6 shown, when the user wears the earphone 10, the second earplug 300 enters the ear canal 20, and the depth of the earphone 10 entering the ear canal 20 is relatively deep.

[0059] As Figure 7 and Figure 8As shown in the figure, when the user wears the earphone 10 normally, the speaker 130 of the earphone 10, the main body 100 of the earphone 10, the ear canal 20 and the eardrum 30 form a cavity, which is called the front cavity 40 of the earphone. The acoustic characteristics of the front cavity 40 of the earphone will directly affect the acoustic performance of the earphone 10. The acoustic characteristics of the front cavity 40 of the earphone mainly include the front cavity volume and airtightness, and the acoustic performance of the earphone 10 mainly includes frequency response and resonance frequency. There are significant differences in the airtightness of the front cavity 40 of semi-in-ear earphones and in-ear earphones. Therefore, under the same other conditions, there are significant differences in the acoustic performance between semi-in-ear earphones and in-ear earphones. By changing the airtightness of the front cavity 40 of the earphone, that is, the airtightness in the ear canal, the acoustic performance of the earphone 10 can be changed.

[0060] The earphone 10 of the present application can change the in-ear depth of the earphone 10 by detachably installing the first earplug 200 or the second earplug 300 on the main body 100, so that the earphone 10 can be switched between a semi-in-ear earphone and an in-ear earphone, and the acoustic characteristics of the front cavity 40 of the earphone can be adjusted, thereby adjusting the acoustic performance of the earphone 10. When the first earplug 200 is installed on the main body 100, the earphone 10 is a semi-in-ear earphone. When the user wears the earphone 10, a part of the first earplug 200 enters the ear canal 20, which will not cause compression to the ear canal 20 and is not easy to fall off, so that the user's wearing experience is better. When the first earplug 200 enters the ear canal 20, it can cooperate well with the ear canal 20, and the sound insulation effect is better, so that the airtightness of the front cavity 40 of the earphone is better, and the acoustic performance of the earphone 10 is improved. When the second earplug 300 is installed on the main body 100, the earphone 10 is an in-ear earphone. When the user wears the earphone 10, a part of the second earplug 300 enters the ear canal 20, which will not cause compression to the ear canal 20 and is not easy to fall off, so that the user's wearing experience is better. When the second earplug 300 is installed on the main body, the air leakage hole can reduce the airtightness of the front cavity 40 of the earphone, avoid the formation of air pressure difference between the inside of the ear canal 20 and the outside, so as to avoid the sound during speaking from forming an echo in the ear canal 20 and improve the openness of the sound quality of the earphone 10. The in-ear depth when the second earplug 300 is assembled on the main body 100 is less than that of a traditional in-ear earphone, so as to improve the problem of intrusion feeling when the user wears the earphone 10. When the first earplug 200 is installed on the main body 100 and when the second earplug 300 is installed on the main body 100, the airtightness of the front cavity 40 of the earphone is close, so that the earphone 10 has approximate acoustic characteristics in the two states, and the sound quality of the earphone 10 is not easily affected in the two states.

[0061] As Figure 9 and Figure 10As shown, in one embodiment, the main body 100 includes a front cover 120, a rear housing 110, and a speaker 130. The front cover 120 covers the rear housing 110. The front cover 120 and the rear housing 110 form an accommodation space. The speaker 130 is fixed within the accommodation space, and the sound-emitting part of the speaker 130 faces the front cover 120. The front cover 120 and the rear housing 110 are made of plastic or plastic or metal, so that the main body 100 has a rigid structure to protect the electronic components within the main body 100. An end face 121 is formed on the end of the front cover 120 that is away from the rear housing 110. The front cover 120 includes a sound outlet nozzle 126 that protrudes from the end face 121. The sound outlet nozzle 126 has a cylindrical structure. The sound outlet nozzle 126 is provided with a first sound outlet channel 128 that communicates with the accommodation space. The sound emitted by the speaker 130 can be transmitted through the first sound outlet channel 128. A first clamping position 127 is provided at the end of the sound outlet nozzle 126 that is away from the end face 121. The first clamping position 127 surrounds the outer periphery of the sound outlet nozzle 126. The outer contour diameter of the cross section of the first clamping position 127 is greater than the outer contour diameter of the cross section of the sound outlet nozzle 126. When the first earplug 200 or the second earplug 300 is installed on the main body 100, the first clamping position 127 can clamp the first earplug 200 or the second earplug 300 to prevent the first earplug 200 or the second earplug 300 from falling off. In one embodiment, the front cover 120 is an integrally formed structure. In another embodiment, the outer contour of the cross section of the sound outlet nozzle 126 can also be a polygon such as a triangle, a quadrilateral, a pentagon, etc., which is not specifically limited herein.

[0062] As Figure 11 and Figure 12As shown, in one embodiment, the first earplug 200 can be installed on the main body 100 and can be detached from the main body 100. A second sound outlet channel 220 is provided inside the first earplug 200. When the first earplug 200 is installed on the main body 100, the first sound outlet channel 128 communicates with the second sound outlet channel 220, so that the sound emitted by the speaker 130 can be transmitted through the first sound outlet channel 128 and the second sound outlet channel 220. The first earplug 200 is provided with a second clamping position 210, and the second clamping position 210 can cooperate with the first clamping position 127 so that the first earplug 200 is installed on the main body 100 and will not fall off the main body 100. The second clamping position 210 is located in the second sound outlet channel 220 and has an elastic soft structure. During the process of installing the first earplug 200 on the main body 100, as the first earplug 200 approaches the main body 100, the second clamping position 210 contacts the first clamping position 127. The first clamping position 127 is made of a harder material, and the second clamping position 210 is made of a softer material. Through extrusion, the second clamping position 210 deforms, providing a channel for the first clamping position 127 so that the second clamping position 210 can move to the side of the first clamping position 127 facing the front cover 120. The first clamping position 127 and the second clamping position 210 are engaged, and an interference fit is formed between the second clamping position 210 and the surface of the sound outlet nozzle 126 to prevent air from flowing between the surface of the second clamping position 210 and the sound outlet nozzle 126. In one embodiment, the material of the first earplug 200 can be a soft material such as rubber, and the first earplug 200 is an integrally formed structure.

[0063] As Figure 13 and Figure 14As shown, in one embodiment, the second earplug 300 can be mounted on the main body 100 and can be detached from the main body 100. A third sound outlet channel 320 is formed inside the second earplug 300. When the second earplug 300 is mounted on the main body 100, the first sound outlet channel 128 communicates with the third sound outlet channel 320, so that the sound emitted by the speaker 130 can be transmitted through the first sound outlet channel 128 and the third sound outlet channel 320. The second earplug 300 is provided with a third clamping position 310, and the third clamping position 310 can cooperate with the first clamping position 127 so that the second earplug 300 is mounted on the main body 100 and will not fall off the main body 100. The third clamping position 310 is located inside the third sound outlet channel 320 and has an elastic soft structure. During the process of mounting the second earplug 300 on the main body 100, as the second earplug 300 approaches the main body 100, the third clamping position 310 contacts the first clamping position 127. The material of the first clamping position 127 is relatively hard, and the material of the third clamping position 310 is relatively soft. Through extrusion, the third clamping position 310 deforms, providing a channel for the first clamping position 127 so that the third clamping position 310 can move to the side of the first clamping position 127 facing the front cover 120. The first clamping position 127 and the third clamping position 310 are engaged, and an interference fit is formed between the third clamping position 310 and the surface of the sound outlet nozzle 126, preventing air from flowing between the third clamping position 310 and the surface of the sound outlet nozzle 126. In one embodiment, the material of the second earplug 300 can be a soft material such as rubber, and the second earplug 300 is an integrally formed structure.

[0064] As Figure 11 shown, in one embodiment, the front cover 120 is provided with an air vent 122, and the air vent 122 extends to the end face 121, that is, the air vent 122 penetrates through the front cover 120 in the thickness direction of the front cover 120, so that the air inside the main body 100 can flow out. The air vent 122 is close to the sound outlet nozzle 126 and there is a certain distance between the air vent 122 and the sound outlet nozzle 126. In the state where the first earplug 200 is mounted on the main body 100, the contour of the edge of the first earplug 200 coincides with the contour of the edge of the end face 121. The first earplug 200 and the main body 100 form an integral outer shape, and the first earplug 200 covers and closes the air vent 122. The distance between the end of the first earplug 200 away from the main body 100 and the end face 121 is L1. When the user wears the earphone 10 with the first earplug 200, the first earplug 200 enters the ear canal 20, and the depth of entry into the ear canal 20 is relatively shallow. The rest of the earphone 10 is located outside the ear canal 20. The first earplug 200 fits well with the ear canal 20 and can deform according to the shape of the ear canal 20, so that the sealing performance between the earphone 10 and the ear canal 20 is good. The airtightness of the front cavity 40 of the earphone is better than that of traditional semi-in-ear earphones, so that the earphone 10 has a better sound insulation effect and a better low-frequency response in acoustic performance. For different groups of people, the first earplug 200 with different sizes can be designed according to the size of the ear canal 20, so that the earphone 10 of the present application can adapt to different groups of people.

[0065] As shown Figure 13 In one embodiment, when the second earplug 300 is installed on the main body 100, the area of the region enclosed by the contour of the edge of the second earplug 300 is smaller than the area of the region enclosed by the contour of the edge of the end face 121, and there is a gap between the second earplug 300 and the end face 121, and the end face 121 is not covered by the second earplug 300, so that the air vent hole 122 is exposed. The distance between the end of the second earplug 300 far from the main body 100 and the end face 121 is L2, and L2 is greater than L1. When the user wears the earphone 10 with the second earplug 300, the second earplug 300 enters the ear canal 20, and the depth of entry into the ear canal 20 is relatively deep, and the rest of the earphone 10 is located outside the ear canal 20. The second earplug 300 can fit well with the ear canal 20 and can deform according to the shape of the ear canal 20, improving the user's comfort. The air vent hole 122 of the earphone 10 will not be covered by the second earplug 300, so that the gas inside the main body 100 can flow out from the air vent hole 122, which can reduce the airtightness of the front cavity 40 of the earphone, and can solve the problem of poor wearing experience caused by the air pressure difference between the inside and outside of the ear canal 20 when wearing an in-ear earphone. At the same time, it also makes the airtightness and acoustic characteristics of the earphone 10 in the in-ear form closer to those of a semi-in-ear earphone, so that the sound quality experience of the earphone 10 in the semi-in-ear form and the in-ear form remains basically unchanged. For different populations, the second earplug 300 of different sizes can be designed according to the size of the ear canal 20, so that the earphone 10 of the present application can adapt to different populations.

[0066] In another embodiment, the air vent hole 122 is located on the hole wall of the sound outlet nozzle 126 and at one end of the sound outlet nozzle 126 close to the end face 121. When the first earplug 200 is installed on the main body 100, the air vent hole 122 is covered and sealed by the second clamping position 210, and the airtightness of the front cavity 40 of the earphone is better than that of a traditional semi-in-ear earphone, so that the earphone 10 has a better sound insulation effect and a better low-frequency response in acoustic performance. When the second earplug 300 is installed on the main body 100, the air vent hole 122 is located on the side of the third clamping position 310 close to the end face 121, so that the air vent hole 122 will not be sealed by the third clamping position 310, that is, the air vent hole 122 will not be covered or sealed by the second earplug 300, so that the gas inside the first sound outlet channel 128 can flow out from the air vent hole 122, which can reduce the airtightness of the front cavity 40 of the earphone, and can solve the problem of poor wearing experience caused by the air pressure difference between the inside and outside of the ear canal 20 when wearing an in-ear earphone. At the same time, it also makes the airtightness and acoustic characteristics of the earphone 10 in the in-ear form closer to those of a semi-in-ear earphone, so that the sound quality experience of the earphone 10 in the semi-in-ear form and the in-ear form remains basically unchanged.

[0067] As Figure 15As shown, in one embodiment, the front cover 120 is not provided with an air vent 122. When the second earplug 300 is installed on the main body 100, the third clamping position 310 is engaged with the first clamping position 127, and there is a gap 123 between the third clamping position 310 and the sound outlet nozzle 126, forming an air leakage channel of the earphone 10, reducing the airtightness between the second earplug 300 and the sound outlet nozzle 126, so that the air inside the main body 100 can flow out successively through the first sound outlet channel 128, the third sound outlet channel 320 and the gap 123, reducing the airtightness of the front cavity 40 of the earphone, which can solve the problem of poor wearing experience caused by the air pressure difference inside and outside the ear canal 20 when wearing the in-ear earphone. At the same time, it also makes the airtightness and acoustic characteristics of the earphone 10 in the in-ear form closer to those of the semi-in-ear earphone, so that the sound quality experience substrate of the earphone 10 in the semi-in-ear form and the in-ear form remains unchanged.

[0068] As Figure 16 and Figure 17 As shown, in one embodiment, the front cover 120 is not provided with an air vent 122, and a notch 124 is provided on the third clamping position 310 of the second earplug 300. When the second earplug 300 is installed on the main body 100, the third clamping position 310 is engaged with the first clamping position 127, and the notch 124 on the third clamping position 310 forms an air leakage channel of the earphone 10, so that the air inside the main body 100 can flow out successively through the first sound outlet channel 128, the third sound outlet channel 320 and the notch 124, reducing the airtightness of the front cavity 40 of the earphone, which can solve the problem of poor wearing experience caused by the air pressure difference inside and outside the ear canal 20 when wearing the in-ear earphone. At the same time, it also makes the airtightness and acoustic characteristics of the earphone 10 in the in-ear form closer to those of the semi-in-ear earphone, so that the sound quality experience substrate of the earphone 10 in the semi-in-ear form and the in-ear form remains unchanged.

[0069] The earphone 10 of the present application can change the insertion depth of the earphone 10 by detachably installing the first earplug 200 or the second earplug 300 with different sizes and shapes on the main body 100, enabling the earphone 10 to switch between a semi-in-ear earphone and an in-ear earphone, and can adjust the acoustic characteristics of the front cavity 40 of the earphone, thereby adjusting the acoustic performance of the earphone 10. When the first earplug 200 is installed on the main body 100, the earphone 10 is a semi-in-ear earphone. When the user wears the earphone 10, the first earplug 200 enters the ear canal 20, does not cause compression to the ear canal 20 and is not easily detached, resulting in a better wearing experience for the user. When the first earplug 200 enters the ear canal 20, it can fit well with the ear canal 20, with a better sound insulation effect, making the airtightness of the front cavity 40 of the earphone better and improving the acoustic performance of the earphone 10. When the second earplug 300 is installed on the main body 100, the earphone 10 is an in-ear earphone. When the user wears the earphone 10, the second earplug 300 enters the ear canal 20, does not cause compression to the ear canal 20 and is not easily detached, resulting in a better wearing experience for the user. The second earplug 300 can reduce the airtightness of the front cavity 40 of the earphone through the air vent hole 122 or the air release channel, avoiding the formation of an air pressure difference between the inside of the ear canal 20 and the outside world, thereby preventing the sound during speaking from forming an echo in the ear canal 20 and improving the sense of openness of the sound quality of the earphone 10. The insertion depth of the second earplug 300 when assembled on the main body 100 is less than that of a traditional in-ear earphone, thereby being able to improve the problem of the intrusion feeling when the user wears the earphone 10. When the first earplug 200 is installed on the main body 100 and when the second earplug 300 is installed on the main body 100, the airtightness of the front cavity 40 of the earphone is basically the same, so that the earphone 10 has approximate acoustic characteristics in the two states, and the sound quality of the earphone 10 is not easily affected in the two states.
