The embodiment of the utility model provides an open earphone which is used for being hung on a user ear 3, wherein the user ear 3 comprises an auditory canal 31, an auricle 32 and an auricle, the open earphone specifically comprises an ear hanging unit 1 and a main body unit 2, the ear hanging unit 1 comprises a deformable main body part 11 and a connecting end part 12 arranged at one end of the main body part 11, and the connecting end part 12 is rotationally connected with the main body unit 2; the main body unit 2 is provided with a sound outlet 21; the deflection angle and the separation distance of the sound outlet 21 relative to the auditory canal 31 can be adjusted by deforming and/or rotating the driving body 11 and the body unit 2. The main body 11 is made of a flexible material.

It should be noted that, compare single revolution mechanic and adjust, this scheme is through deformable main part 11 and rotatable link end 12, and biax rotation mode plays the regulation effect to main part unit 2 jointly, has more nimble adjustment mode to adapt to different use needs, avoid appearing at the condition that a certain position blocked.

Wherein the different usage needs of the user include an open and a listening function, favoring the open function: at this time, the user needs to receive more external sound, so that the deflection angle and the interval distance can be increased, and the interference of the sound outlet 21 to the user is reduced; favoring the listening function: at this time, the user needs more receiving earphone sound, and the deflection angle and the distance can be reduced, so that the sound outlet 21 can be more easily transmitted into the auditory canal 31.

The working principle of the utility model is as follows: when the open earphone works, the ear-hanging unit 1 is worn on the ear 3 of a user, the ear-hanging unit 1 is attached to the outer edge of the auricle, the main body unit 2 is arranged in the auricle, the sound outlet 21 is close to the auditory canal 31, and when the user needs to adjust the wearing position, the deflection angle and the interval distance of the sound outlet 21 relative to the auditory canal 31 are adjusted by driving the main body part 11 to deform and/or rotate the main body unit 2, so that different listening effects are presented to the sound outlet 21 to match the user's needs; compared with conventional earphone equipment, the open earphone can adjust the wearing position in a double-shaft rotation mode, has more flexible operation space, adapts to different use needs and improves wearing comfort of a user.

Referring to fig. 1, fig. 1 is a schematic view of a user wearing the open earphone with an ear 3, wherein an arrow direction in the illustration is a rotation direction of a main body unit 2; fig. 2 is a schematic diagram of a model of an ear 3 of a user, and fig. 3 is a schematic diagram of the open earphone;

for convenience of explanation of the composition in this embodiment, a virtual coordinate system is constructed with an auricle (toward the rear side of the human head) parallel to the user's ear 3 as an M-axis, an N-axis along the length direction of the ear canal 31 and toward the outside of the ear (away from the human head), and a Z-axis in the vertical direction, with the center point of the preset depth of the ear canal 31 as the origin.

In this embodiment, the separation distance ranges between 0 and 20 mm. Wherein, the interval distance is the interval distance of the center point of the sound outlet 21 relative to the Z axis; the offset direction can be any direction of the two sides of the Z axis;

further, the main body 11 is provided so as to be attached to the outer edge of the auricle, and a holding space for holding the auricle is formed between the main body 11 and the main body unit 2; the clamping force of the main body 11 on the auricle ranges from 0 to 5N; wherein more preferably 0.6N, when clamping force is 0.6N, on the one hand, ear-hanging unit 1 can well keep wearing on the auricle, and on the other hand, ear-hanging unit 1 is less to the sense of oppression of auricle, can guarantee user's wearing comfort level.

Specifically, the deflection angle includes a first deflection angle and a second deflection angle, the first deflection angle is an included angle between the main body unit 2 and the first direction, and the second deflection angle is an included angle between the main body unit 2 and the length direction of the auditory canal 31; the first direction is the direction of the helix 32. It should be noted that, the first direction is the M-axis direction in fig. 1 and 2.

Wherein the first deflection angle ranges from 0 ° to 45 °, and the second deflection angle ranges from 0 ° to 20 °.

The user's ear 3 has a substantially wide bottom and narrow configuration, that is, has a larger upper offset than a lower offset in the N-axis direction. So that after wearing the earphone, the main unit 2 is preferably disposed obliquely to the vertical. This way of wearing is advantageous in that the technical effect of the present solution is achieved in that after biaxial rotational adjustment, the body unit 2 is always attached to the user's outer ear and spaced apart from the inside of the earhole, forming an open listening function.

The open earphone has a plurality of wearing positions in combination with the construction characteristics of the user ear 3, and is a first wearing position in combination with fig. 4; in this position, the first deflection angle is greater, an alternative angle such as 40; the second deflection angle is smaller, an alternative angle being e.g. 6 °; taking the sound outlet 21 as an example, the distance in the Z-axis direction is D1, and optionally D1 is 8mm.

Further wearing positions, such as the nth position, are not illustrated in detail. The common characteristics are: the greater the upward/downward deflection of the sound outlet aperture 21 relative to the ear canal 31, the greater the first deflection angle, which may actually be between 0 and 45 degrees; the smaller the second deflection angle, the more upwardly the sound outlet aperture 21 is deflected relative to the ear canal 31, which may actually be between 0 and 20 degrees; the more the sound outlet 21 deviates downwards from the auditory canal 31, the larger the second angle of deflection, which may actually be between 0 and 20 degrees; taking the sound outlet 21 as an example, the distance between the sound outlet 21 and the Z axis may be adjusted to be between 0 and 20mm as the sound outlet 21 is deviated upward/downward from the auditory canal 31. More specifically, the distance of the sound outlet 21 from the auditory canal 31 should be not more than 20mm in order to receive the sound of the sound outlet 21.

In both the first wearing position and the second wearing position, the auricle is held by the ear-hook unit 1 and the main body unit 2, and the distance between the ear-hook unit 1 and the tip contact of the main body unit 2 is between 2mm and 15mm, which is substantially equal to the thickness of the auricle.
