In one embodiment, as shown in fig. 2 to 3, the speaker unit 100 further includes a ring-shaped gasket 40, the ring-shaped gasket 40 is disposed on the speaker cover 30 and located at one side of the front sound cavity 111, and a central opening of the ring-shaped gasket 40 is disposed around an outer periphery of the sound-emitting area 31. Specifically, the thickness of the annular gasket 40 is uniform to fill the front sound cavity 111, wherein the thickness of the annular gasket 40 is the same as the maximum depth of the front sound cavity 111, so that compared with the structure that the existing horn cover 30 is directly and flatly placed at the opening of the sound cavity 11, the outermost side of the annular gasket 40 can be directly located at the opening of the sound cavity 11 (i.e. the outermost side of the annular gasket 40 is flush with the opening of the sound cavity 11 close to the maximum depth), so that the thickness of the horn housing 10 can be effectively reduced on the whole, the produced earphone is lighter, and good use experience is provided for users.

In one embodiment, as shown in fig. 1 to 3, the speaker unit 100 further includes an annular ear pad 50, the annular ear pad 50 is mounted on the speaker housing 10 and covers the annular gasket 40, and the middle opening of the annular ear pad 50 is disposed to avoid the sound-emitting region 31. Specifically, the annular ear pad 50 is soft and elastic, and when the ear pad is worn, the annular ear pad 50 is attached to the ear of a person, so that the user can have a good wearing experience.

In one embodiment, as shown in FIGS. 2-4, the speaker unit 100 further includes a noise reduction microphone 60, the noise reduction microphone 60 being mounted on the speaker cover 30. Specifically, the noise reduction microphone 60 is used for collecting the noise of the surrounding environment and emitting reverse sound waves to neutralize the noise, so as to achieve the purpose of noise reduction, and the user can avoid self-oscillation when listening to music.

In one embodiment, as shown in fig. 3 to 5, the speaker cover 30 is provided with a mounting cavity 32, the noise reduction microphone 60 is mounted in the mounting cavity 32, when the speaker cover 30 is worn to be attached to a human ear, a horizontal line passing through the center of a plane where the speaker cover 30 is located is taken as a reference line a1, the mounting cavity 32 is located below the reference line a1 and close to an tragus of the human ear, a connecting line between the center of the mounting cavity 32 and the center of the speaker cover 30 is an offset line a2, an included angle between the reference line a1 and the offset line a2 is an offset angle a, and the size range of the offset angle a is 20 ° to 40 °. Specifically, according to human engineering, the ear socket of the human ear is generally at a position where the ear canal is shifted downward by 20 ° to 40 °, and the position of the mounting cavity 32 for mounting the noise reduction microphone 60 is set within a range of 20 ° to 40 ° below the horizontal line of the speaker housing 10, so that the noise reduction microphone 60 can be closest to the position of the offset line a2 of the ear socket of the human body when the user uses the speaker, or the noise reduction microphone 60 is just located at the position of the ear socket of the human body, and then the noise reduction microphone 60 can collect the external noise to the maximum in the direction of the offset line a2 to reduce the noise, thereby effectively improving the noise reduction effect, and the blocking effect of the noise reduction microphone 60 itself can be utilized to effectively reduce the external noise from entering the ear socket, thereby improving the use experience of the user.
