[0033] In some embodiments, the present application discloses an ergonomic ear hook 2 for an acoustic device, with emphasis on the ergonomic ear hook 2 for an acoustic device. The structural features of the ergonomic ear hook 2 for an acoustic device are discussed below.

[0034] The ergonomic ear hook 2 for acoustic equipment may include a main hanging body connected to the earplug and the external structure 3 respectively, a contact point 23 that contacts the head at the ear tip, and a avoidance position 24 that avoids the cartilage of the helix. The avoidance position 24 is arranged on the inner side of the end of the main hanging body close to the earplug 1, and the contact point 23 is arranged at the highest point of the main hanging body facing the head away from the earplug 1, and the contact point 23 exceeds the plane where the earplug 1 is located or the surface of one side (regarded as a reference surface). Preferably, the main hanging body may be a curved cylindrical structure with a circular cross-section. It can be understood that in some other embodiments, the main hanging body may be an elliptical cylinder or an irregular cylinder with an elliptical or other smooth closed curve cross-section. In order to better adapt to the shape of each wearer's head, the main hanging body may be an elastic structure with a certain adjustment space along the direction of the head to prevent excessive squeezing of the head or the problem of poor fit.

[0035] In some embodiments, the main hanging body includes a front hanging section 21 connected to the earplug 1, a rear hanging section 22 whose front projection is consistent with the arc of the ear root, the front hanging section 21 is connected to the earplug 1, the rear hanging section 22 is connected to the external structure 3, and the rear hanging section 22 is connected to the end of the front hanging section 21 away from the earplug 1. Among them, the curvature of the front hanging section 21 is partially or completely greater than the curvature of the rear hanging section 22. It can be understood that in order to make the front hanging section 21 and the rear hanging section 22 have a smooth transition, in this embodiment, the front hanging section 21 and the rear hanging section 22 can have the same curvature, which is not specifically limited here.

[0036] Further, in order to facilitate the description of the curvature of the main hanging body, please refer to Figure 2 and Figure 3, the orthographic projection of the surface of the main hanging body opposite to the outer contour of the ear is an arc L, whose curvature range is 0.01-0.16, and the radius range is 5.13mm-29.60mm. Starting from the end of the main hanging body close to the external structure 3 to the end close to the earplug 1, the radius of the arc L gradually decreases. Preferably, the orthographic projection of the surface of the front hanging section 21 opposite to the outer contour of the ear is an arc L1, whose curvature range is 0.09-0.14, and the radius range is 7.13mm-9.13mm. The orthographic projection of the surface of the rear hanging section 22 opposite to the outer contour of the ear is an arc L2, whose curvature range is 0.03-0.09, and the radius range is 9.13mm-27.60mm. Among them, the arc L is the assembly of the arc L1 and the arc L2. It can be understood that the front hanging section 21 can include multiple cylindrical sections with different curvatures and different radii (or elliptical cylinders or irregular cylinders), for example, a cylindrical section with a curvature of 0.14 and a radius of 7.13 mm, plus a cylindrical section with a curvature of 0.11 and a radius of 9.13 mm connected end to end. Similarly, the rear hanging section 22 can include multiple cylindrical sections with different curvatures and different radii (or elliptical cylinders or irregular cylinders), for example, a cylindrical section with a curvature of 0.11 and a radius of 9.13 mm, plus a cylindrical section with a curvature of 0.09 and a radius of 11.25 mm, plus a cylindrical section with a curvature of 0.03 and a radius of 27.60 mm connected end to end. Alternatively, the front hanging section 21 and the rear hanging section 22 can be composed of more cylindrical sections with different curvatures and different radii (or elliptical cylinders or irregular cylinders), which can better fit the outer contour of the ear.

[0037] In some embodiments, see Figure 4 The contact point 23 is located away from the earplug 1 and is located at the highest point of the ear hook 2 facing the head, that is, the contact point 23 is located between the front hanging section 21 and the rear hanging section 22. Figure 3 In the direction of the earplug 1, the contact point 23 is beyond the plane of the earplug 1 to the right. Preferably, the distance between the contact point 23 and the center of the earplug 1 is in the range of 26.5 mm to 30.5 mm, for example, 26.5 mm, 28.3 mm, 29.7 mm, etc.

[0038] In some embodiments, see Figure 5 The avoidance position 24 is arranged on the inner side of the end of the ear hook 2 close to the earplug 1, that is, the avoidance position 24 is arranged on the inner side of the front hanging section 21 facing the rear hanging section 22. Preferably, the front hanging section 21 is a cylindrical structure, and the avoidance position 24 is a concave area on the cylinder, which is used to avoid the crus of the helix when worn, thereby reducing the discomfort caused by squeezing the crus of the helix.

[0039] In order to intuitively indicate the degree of depression of the avoidance position 24, a starting point C1, a midpoint C2 and an end point C3 are sequentially set on the avoidance position 24 along the axial direction of the front hanging section 21. The avoidance position 24 is depressed from the starting point C1 and extends along the midpoint C2 to the end point C3, wherein the curvature of the arc formed by connecting the starting point C1, the midpoint C2 and the end point C3 is 0.09-0.12. It can be understood that the length of the avoidance position 24 along the axial direction of the front hanging section 21 is less than or equal to the length of the front hanging section 21.

[0040] Furthermore, the depth of the depression at the starting point C1 is 0.49 mm to 1.49 mm, the depth of the depression at the midpoint C2 is 0.52 mm to 1.52 mm, and the depth of the depression at the end point C3 is 0.37 mm to 1.37 mm. Among them, the depth of the depression at the midpoint C2 is greater than the depth of the depression at the starting point C1 and greater than the depth of the depression at the end point C3. Figure 6 FIG. 4 shows an embodiment of the depression depth of the midpoint C2 , in which the depression depth of the midpoint C2 is 1 mm.

[0041] By implementing the utility model, the following beneficial effects are achieved:

[0042] The avoidance position 24 of the ergonomic ear hook 2 for acoustic equipment of the utility model can avoid the cartilage of the helix of the ear, and the abutment point 23 can be close to the head at the tip of the ear, completely fit the ear, and conform to the ergonomic design, thereby reducing the tenderness caused by squeezing the ear, and at the same time can be worn stably.

[0043] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above embodiments or technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model, that is, the embodiments described in "some embodiments" can be freely combined with any of the above and below embodiments.
