[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0029] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0030] See also Figures 1 to 3 As shown, according to one aspect of the present invention, there is provided an earphone capable of automatically adjusting position, comprising:

[0031] The speaker fixing member 2 is provided with an accommodating space with at least one end open. At least two penetrating assembly holes 21 are provided on the side wall of the speaker fixing member 2. The assembly holes 21 are communicated with the accommodating space.

[0032] The speaker unit 3, at least two assembly columns 31 are fixedly provided on the side wall of the speaker unit 3, the number of the assembly columns 31 is the same as the number of the assembly holes 21 and the positions correspond, the speaker unit 3 is arranged in the accommodating space, the assembly columns 31 can be integrated with the speaker unit 3, for example, manufactured in the form of one-piece injection molding, or connected by subsequent welding. Of course, the assembly columns 31 can also be set as a split type with the speaker unit 3, such as a snap-on method, and the assembly columns 31 are detachably fixed to the speaker unit 3.

[0033] The earphone body 1 and the speaker fixing member 2 are fixedly connected to the earphone body 1 , and the connection method is preferably a detachable fixed connection.

[0034] Among them, the cross-sectional area of the assembly column 31 is equal to or smaller than the cross-sectional area of the assembly hole 21. When the cross-sectional areas of the assembly column 31 and the assembly hole 21 are both circular, and the cross-sectional area of the assembly column 31 is equal to the cross-sectional area of the assembly hole 21, the assembly column 31 can rotate in the assembly hole 21. When the cross-sectional area of the assembly column 31 is smaller than the cross-sectional area of the assembly hole 21, the assembly column 31 can move freely in the assembly hole 21. When the speaker unit 3 is assembled into the accommodating space, the assembly columns 31 are respectively engaged in the corresponding assembly holes 21. Since the assembly column 31 can rotate or move freely in the assembly hole 21, and the assembly column 31 is fixed on the speaker unit 3, the speaker unit 3 can rotate or move freely in the accommodating space, thereby adjusting the position of the speaker unit 3 in the accommodating space.

[0035] In this embodiment, at least two assembly columns 31 are provided on the side wall of the speaker unit 3, and at least two penetrating assembly holes 21 are provided on the side wall of the speaker fixing member 2. The number of the assembly columns 31 is the same as the number of the assembly holes 21 and the positions correspond to each other. The speaker unit 3 is fixed to the accommodating space of the speaker fixing member 2 through the cooperation between the assembly columns 31 and the assembly holes 21.

[0036] When the earphones are worn, the user's ears or skin will exert a certain amount of pressure on the speaker unit 3. Since the assembly column 31 can rotate or move freely in the assembly hole 21, the speaker unit 3 will contact the user's ear or skin over a larger area. The pressure of the speaker unit 3 in the area in contact with the user's ear or skin tends to be uniform, thereby increasing the user's comfort.

[0037] In one embodiment, see Figure 4 As shown, there are two mounting posts 31 and two mounting holes 21. The mounting posts 31 are cylindrical or elliptical. A cylindrical shape is preferred, and the mounting hole 21 is a waist-shaped hole or a round hole. The size of the mounting posts 31 is smaller than that of the waist-shaped hole or the round hole. The small size of the mounting posts 31 allows for easy and free movement in the mounting hole 21, and the mounting posts 31 and the mounting hole 21 are also easier to process.

[0038] When there are two assembly columns 31 and two assembly holes 21, and the two assembly columns 31 are symmetrically arranged, the two assembly holes 21 are also symmetrically arranged, when the speaker unit 3 contacts the user's ear or skin, the assembly column 31 in the area where the speaker unit 3 first contacts can move in the assembly hole 21, and the speaker unit 3 tilts up and down in the direction of the line connecting the two assembly columns 31. At the same time, the assembly column 31 can rotate around the axis of the assembly column 31 in the assembly hole 21, so the speaker unit 3 can rotate around the axis of the assembly column 31 in the accommodating space. Therefore, the speaker unit 3 has at least two degrees of freedom in two directions. If the speaker unit 3 moves left and right in the direction of the line connecting the two assembly columns 31, the speaker unit 3 has three degrees of freedom, so that the position of the speaker unit 3 can be adjusted according to the size of the user's head and the specific shape of the contact surface, so that the entire speaker unit 3 is in maximum contact with the user's head and the pressure is kept uniform, thereby improving the user's comfort and user experience.

[0039] If the two assembly posts 31 and the two assembly holes 21 are not symmetrically arranged, and the cross-sectional area of the assembly post 31 is smaller than the cross-sectional area of the assembly hole 21, the assembly post 31 can move freely in the assembly hole 21. The assembly post 31 can move up and down in the assembly hole 21 as one degree of freedom, and the speaker unit 3 can tilt in the direction of the line connecting the centers of the two assembly holes 21 as the second degree of freedom. The symmetrical arrangement of the assembly post 31 and the assembly hole 21 has a better adjustment effect than the asymmetrical arrangement, and the adjustment range is larger.

[0040] In one embodiment, see Figure 4 As shown, the number of the mounting posts 31 is 3 to 5 and they are evenly arranged on the speaker unit 3. The number of the mounting holes 21 is 3 to 5 and they are evenly arranged on the speaker fixing member 2.

[0041] To prevent the speaker unit 3 from rotating too far and to prevent the two mounting posts 31 from being broken when the speaker unit 3 is subjected to a relatively large external force due to their weak strength, this problem can be solved by increasing the number of mounting posts 31. Preferably, the number of mounting posts 31 and mounting holes 21 is 3 to 5.

[0042] For example, when the number of assembly columns 31 and assembly holes 21 is 3 and they are evenly arranged, after the speaker unit 3 contacts the user's ear or skin, the assembly column 31 in the first contact area moves downward in its corresponding assembly hole 21, and the other two assembly columns 31 move accordingly in their corresponding assembly holes 21 according to the order of contact with the ear or skin, among which the assembly column 31 in the last contact area moves upward in its corresponding assembly hole 21. The effect is similar to controlling the position of the speaker unit 3 in the accommodating space by using three adjustment points, so that the speaker unit 3 is adjusted accordingly according to the specific shape of the user's ear or skin position, so that the entire speaker unit 3 is in maximum contact with the user's head and maintains even pressure.

[0043] The number of the assembly posts 31 and the assembly holes 21 is 4 or 5, and the principle is the same as that of the 3-assembly posts, which will not be described in detail.

[0044] In one embodiment, see Figure 4 As shown, the end of the speaker unit 3 facing the user extends out from the opening of the accommodating space. The closest distance between the end surface of the speaker unit 3 facing the user and the speaker fixing member 2 can be any value between 0.1mm and 10mm.

[0045] The speaker unit 3 extends out of the accommodating space toward one end of the user, and part of the speaker unit 3 is outside the accommodating space. When the earphones are worn, the speaker unit 3 first contacts the user's ear or skin, reducing the influence of the speaker fixing part 2 on the contact between the speaker unit 3 and the user.

[0046] The distance between the end surface of the speaker unit 3 facing the user and the speaker holder 2 can be preferably any value between 0.5mm and 5mm. If the distance is less than 0.5mm, the elastic ear or skin of the user may come into contact with the speaker holder 2, affecting the position adjustment of the speaker unit 3. If the distance is greater than 5mm, the headphone speaker is too thick, affecting the appearance and storage of the headphone.

[0047] Preferably, the accommodating space is a through hole that passes through the speaker fixing member 2 .

[0048] In one embodiment, see Figure 5 As shown, the speaker fixing member 2 includes an upper fixing member 22 and a lower fixing member 23. A portion of the assembly hole 21 is provided on the upper fixing member 22, and another portion of the assembly hole 21 is provided on the lower fixing member 23. The split design facilitates assembly of the speaker unit 3 to the speaker fixing member 2.

[0049] In one embodiment, the wall of the mounting hole 21 is at least partially made of a flexible material. At least the portion of the mounting post 31 that contacts the mounting hole 21 is also made of a flexible material. Using a flexible material prevents the mounting post 31 from sliding and rubbing against the mounting hole 21 during speaker unit 3 position adjustment, thereby preventing unwanted noise.
