[0028] The embodiments of the present application are described below in conjunction with the drawings in the present application. It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0029] Those skilled in the art will appreciate that, unless specifically stated, the "said" and "the" used herein may also include plural forms. It should be further understood that the term "including" used in the specification of the present application refers to the presence of the elements and / or components, but does not exclude the implementation of other features, information, data, steps, operations, elements, components and / or combinations thereof supported by the technical field. The term "and / or" used herein refers to at least one of the items defined by the term, for example, "A and / or B" may be implemented as "A", or as "B", or as "A and B".

[0030] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0031] refer to Figures 1 to 4 The ear clip-type earphones of the present application are characterized by the earphone shell, which is the part that directly reflects the wearing effect. The coordination between the sound-generating device inside the earphone shell and the earphone shell mainly reflects the sound effect and sound quality of the earphones. The power feeding structure integrated inside or outside the earphone shell mainly reflects the endurance performance of the earphones. The earphones involved in the present application can be earphones adapted for a single ear or earphones adapted for both ears. Therefore, the earphones having the earphone shell and the sound-generating device and their power feeding structure constitute an earphone assembly.

[0032] The earphone shell of the present application includes a connecting arm 1 and a front cavity 2 and a rear cavity 3 respectively connected to the two ends of the connecting arm 1. When worn, the connecting arm 1 spans the outer side of the helix, the front cavity 2 abuts against the concha cavity, and the rear cavity 3 abuts against the range from the back of the concha to the back of the earlobe.

[0033] The main body of the connecting arm 1 can be a curved arm with uniform thickness, and the main extension axis of the curved arm is basically on the same plane. For the convenience of subsequent description, the plane is defined as the first reference plane I, and other reference planes or reference lines are defined by the first reference plane I. It should be noted that the "reference plane" or "reference line" involved in the following text of this application is not a plane or straight line in an absolute sense, and fluctuations or fine-tuning should be allowed within the tolerance range of the "reference plane" or "reference line". The connecting arm 1 of the present application is smoothly connected between the front cavity 2 and the rear cavity 3, and its curved arm can be formed by smoothly connecting a plurality of small curved arms with different curvatures. The diameter of each small curved arm can also be obtained by fitting or testing to obtain a specific value. The diameters of each small curved arm can be different, but the transition between each small curved arm should be smooth.

[0034] The front cavity 2 is configured with the first reference plane I as a symmetry plane, so that the two parts separated by the first reference plane I are basically mirror-symmetrical. In the implementation of this embodiment, the main structure of the front cavity 2 is approximately spherical, the side connected to the connecting arm 1 is defined as the rear side, the side opposite to the rear side is defined as the front side, the side facing the rear cavity 3 is defined as the inner side, and the side opposite to the inner side is defined as the outer side.

[0035] The rear side surface of the front cavity 2 is smoothly connected to the end of the curved arm of the connecting arm 1 to form the front root 11. The distance between the inner edge of the front cavity 2 and the reference point of the front root 11 at the projection point of the first reference plane I is in the range of 7.5mm to 9.5mm, thereby forming an outer convex surface 22 structure adapted to the concha cavity on the inner side surface of the front cavity 2. The "adaptation" involved in the embodiment of the present application mainly refers to the outer convex surface 22 being able to rest against the concha cavity as a whole, but not requiring a tight fit, thereby improving the adjustability of the earphone. The reference point of the front root 11 can be defined at the inner connection inflection point between the connecting arm 1 and the front cavity 2 (projected as A, correspondingly, the inner edge of the front cavity 2 is projected as A', and the distance between the two is represented by AA'), or it can be defined at the intersection of the main extension axis of the curved arm and the outer contour of the main body of the front cavity 2. The two reference point methods will result in a difference in the aforementioned distance, which is approximately the radius value of the front root 11.

[0036] A long waist-shaped sound mouthpiece 21 is arranged on the front side of the front cavity 2. The long waist-shaped sound mouthpiece 21 has a long symmetry axis IV and a short symmetry axis perpendicular to each other, wherein the long symmetry axis IV is perpendicular to the first reference plane I, that is, the long waist-shaped sound mouthpiece 21 is arranged vertically. The vertically arranged long waist-shaped sound mouthpiece 21 allows the sound mouthpiece 21 to always align with the ear canal opening with the largest area when the earphone is worn at different heights of the auricle, thereby avoiding the sound mouthpiece 21 being blocked in certain wearing positions, resulting in bass loss and affecting the overall sound quality. Furthermore, the long waist-shaped sound mouthpiece 21 is arranged concave relative to the surface of the front cavity 2, so that a trumpet-shaped structure is formed around the long waist-shaped sound mouthpiece 21, which is conducive to the directional sound emission of the earphone.

[0037] The rear cavity 3 is configured with the first reference plane I at the top, so that the rear cavity 3 is biased downward based on the first reference plane I. In the implementation of this embodiment, the main structure of the rear cavity 3 is approximately waist-shaped, and the waist shape has a long symmetry axis and a short symmetry axis that are perpendicular to each other, wherein the short symmetry axis is horizontally arranged as the second reference line III. The rear cavity 3 is biased downward to avoid interference in the spatial position between the connecting arm 1 and the PCBA components inside the rear cavity 3. The PCBA components are the most complex structures of the components in the earphones, and the requirements for self-assembly and assembly with the earphone shell are high. The rear cavity 3 is biased relative to the connecting arm 1, which is conducive to providing more space for the assembly of PCBA components, thereby reducing the assembly complexity of the earphones. The side of the rear cavity 3 connected to the connecting arm 1 is defined as the rear side, the side opposite to the rear side is defined as the front side, the side facing the front cavity 2 is defined as the inner side, and the side opposite to the inner side is defined as the outer side.

[0038] The rear side surface of the rear cavity 3 is smoothly connected to the end of the curved arm of the connecting arm 1 to form the rear root 12. The distance between the inner side edge of the rear cavity 3 and the reference point of the rear root 12 on the first reference plane I is in the range of 1.5mm~2.5mm, and the inner side surface of the rear cavity 3 is formed to fit the back of the second nail to the back of the earlobe. The inner side surface of the rear cavity 3 is formed to fit the inner concave surface 32 structure, which is adapted to the back of the second nail to the back of the earlobe. Therefore, the degree of convexity of the inner side surface of the rear cavity 3 is significantly smaller than that of the inner side surface of the front cavity 2, which is used to fit the structure of the general auricle. The "fit" involved in the embodiment of the present application mainly refers to the inner concave surface 32 being able to roughly fit the back of the concha, and being adapted to the wearing method close to the tragus notch, and should also be able to extend the fit range to the back of the earlobe. The inner concave surface 32 is configured with the second reference line III as the symmetry line, so that the entire inner side surface of the rear cavity 3 is a symmetrical inner concave surface 32. The reference point of the rear root 12 can be defined at the inner connecting inflection point between the connecting arm 1 and the rear cavity 3 (projected as B, correspondingly, the inner edge of the rear cavity 3 is projected as B', and the distance between the two is represented by BB'), or it can be defined at the intersection of the main extension axis of the curved arm and the outer contour of the main body of the rear cavity 3. The two methods of taking the reference point will result in a difference in the aforementioned distance, which is approximately the radius value of the rear root 12.

[0039] The front side of the rear cavity 3 is provided with a charging shrapnel 5, which is flush with the surface of the rear cavity 3 in the non-charging state. Correspondingly, a pair of mounting holes 31 are provided on the front side of the rear cavity 3 for assembling the charging shrapnel 5. In this embodiment, the line connecting the centers of the pair of mounting holes 31 is used as the first reference line II. When viewed from the front side, the first reference line II is set at an angle to the front cavity 2, and the first reference line II forms an angle α with the long symmetry axis IV of the sound mouthpiece 21, and the value of α is in the range of 10°~15°. Such a setting further improves the adaptability of the rear cavity 3 to the back of the auricle and reduces the occurrence of loose wearing. Furthermore, when the first reference line II is parallel to the long symmetry axis of the rear cavity 3, a pair of mounting holes 31 are arranged on the front side of the rear cavity 3 with the second reference line III as the symmetry line, so that the charging shrapnel 5 assembled in the mounting hole 31 is symmetrically distributed on the front side of the rear cavity 3, which is conducive to improving the uniform pressure of the charging shrapnel 5 during charging and improving the stability of charging.

[0040] Further, refer to Figure 5 The embodiment of the present application further provides an additional sleeve 4 for being sleeved on the surface of the rear cavity 3, and the additional sleeve 4 includes an integrally formed shell, the rear portion of which is opened to form a first notch 41 for avoiding the rear root portion 12; further, the front portion of the shell is opened to form a second notch 42 for avoiding the charging shrapnel 5; further, the first notch 41 and the second notch 42 are connected, so that the shell can be more conveniently sleeved on the surface of the rear cavity 3 through the connected notches. A possible implementation is to open a third notch 43 at the upper part in the wearing state to connect the first notch 41 and the second notch 42, and enable the additional sleeve 4 to be sleeved or removed from the bottom of the rear cavity 3. The function of the additional sleeve 4 is to compensate for the gap after some users wear the earphones, and to enhance the fit and friction between the earphones and the auricle. It can be understood that the shell of the additional sleeve 4 has a suitable thickness, especially in the area close to the auricle. Furthermore, the roughness of the outer surface of the additional sleeve 4 is greater than the roughness of the outer surface of the rear cavity 3. Appropriately changing the characteristics of the surface of the rear cavity 3 is conducive to the use of the earphones in different scenarios, such as sports environments or hot environments with increased sweating, or sports environments with increased shaking. The additional sleeve 4 can also be finely configured with models of different thicknesses and roughnesses to achieve diversified selection.

[0041] In summary, the ear-clip type earphone of the present application has an earphone shell, and the earphone shell includes a connecting arm and a front cavity and a rear cavity respectively connected to the two ends of the connecting arm; the extension axis of the connecting arm is set in the same plane, with the plane as the first reference plane, the front cavity is configured with the first reference plane as the symmetry plane, and a long waist-shaped sound mouth is set on the front side of the front cavity, and the long symmetry axis of the sound mouth is perpendicular to the first reference plane; the rear cavity is configured with the first reference plane at the upper part, and a pair of mounting holes are set on the surface of the rear cavity for configuring charging shrapnel, and the line connecting the centers of the pair of mounting holes is used as the first reference line, and the first reference line is set at an angle to the front cavity. In the ear-clip type earphone of the present application, the rear cavity is set at an angle to the front cavity, which is conducive to adapting to the structure of the front and back of the auricle, and is also conducive to fixing the earphone at different positions along the auricle to adapt to the wearing experience and wearing habits of different users.
