The present application is described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an earphone 100 according to an embodiment of the present application. In this embodiment, an ear-hanging earphone 100 is provided, where the earphone 100 includes a bin assembly 10 and an ear-hanging assembly 20; the bin assembly 10 includes a bin body for accommodating the transducer and other components, and a transducer for converting electrical signals into acoustic signals to provide sound to a user, and/or for collecting sound to convert sound in an environment within a certain distance from the outside into electrical signals; the ear-hook assembly 20 is connected to the bin assembly 10, and is used for keeping the bin assembly 10 at a predetermined position of an ear when the earphone 100 is worn, and meanwhile, the earphone 100 can be effectively prevented from falling off from the ear.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a front view angle of an earphone in a wearing state according to an embodiment of the present disclosure. In this embodiment, when the earphone 100 is worn on the ear 200, the housing assembly 10 is kept within the range of the concha cavity 201 on the front side of the ear 200, so that the transducer 12 disposed in the housing 11 is kept within the range of the concha cavity 201, and thus the earphone 100 can achieve better sound effects.

Referring to fig. 3 in combination, fig. 3 is a graph of the results of testing the acoustic effect of the earphone when the distance between the transducer 12 and the concha cavity is different. The acoustic effect diagram obtained by acoustically testing the earphone 100 when the transducer 12 is at a different distance from the ear canal is shown, wherein the abscissa indicates the frequency of sound in hertz (Hz) and the ordinate indicates the loudness of sound in decibels (dB); the test is a result measured by changing the distance between the transducer 12 and the auditory canal under the same other conditions, namely, a result obtained by performing multiple tests by adopting a controlled variable method, wherein different line types in the figure represent the sound effects of the earphone 100 when the distance between the transducer 12 and the auditory canal is different; wherein the test results include a 0mm distance test result 301, a 5mm distance test result 302, a 10mm distance test result 303, and a 15mm distance test result 304; as can be seen from the figure, the loudness of the 0mm distance test result 301, the 5mm distance test result 302, the 10mm distance test result 303, and the 15mm distance test result 304 are sequentially decreased at the same frequency; it can thus be seen that the closer the transducer 12 is to the concha chamber 201, the greater the loudness of the sound measured by the earphone 100. From this, the closer the transducer 12 is to the ear canal, the better the acoustic effect of the earphone 100. As shown in fig. 2, the concha cavity 201 is the portion closest to the ear canal, and thus, the transducer 12 is held within the concha cavity 201, enabling the earphone 100 to achieve a better acoustic effect.

In general, ear types of different users may be different, for example, the outline size, shape, thickness of the ear 200, and range size of the concha cavity 201 of the ear 200 may be different, and meanwhile, the lateral and longitudinal dimensions of the ear 200 may be different, so when the ear-hanging earphone 100 with the same shape and size is worn by different users, there is a problem that the acoustic effect of the earphone 100 is poor because the ear-hanging assembly 20 is not adapted to the ear type of the user, and the bin assembly 10 cannot be accurately maintained in the concha cavity 201, that is, the transducer 12 cannot be maintained in the range of the concha cavity 201; meanwhile, the problem that the wearing comfort is poor and the wearing stability is poor due to the fact that the ear hanging component 20 is not matched with the ear of the user easily occurs, and the ear hanging component is easy to fall off from the ear 200 easily occurs.

Referring to fig. 4, fig. 4 is a schematic structural diagram of two kinds of ear hook assemblies according to an embodiment of the present application, fig. 4 (a) is a schematic structural diagram of a first kind of ear hook assembly, and fig. 4 (b) is a schematic structural diagram of a second kind of ear hook assembly. The earphone 100 provided in this embodiment includes at least two sets of ear-hook assemblies 20, at least two sets of ear-hook assemblies 20 are interchangeably connected to the bin assembly 10, and at least two sets of ear-hook assemblies 20 have different arc-shaped settings to adapt to different ear types of users, so as to solve the technical problem of the above analysis.

Further, in order to improve wearing comfort of the earphone 100, the ear-hook component 20 is at least partially of a flexible structure 21, that is, the ear-hook component 20 is at least partially soft, so that when the earphone 100 is worn on the ear 200, the flexible structure 21 of the ear-hook component 20 can deform to better fit the ear 200, and the situation that the ear 200 is pressed by the ear-hook component 20 to cause low wearing comfort and pain is caused when the user wears the earphone for a long time is avoided. Wherein the flexible structure 21 is deformed into a recoverable or elastic deformation. In particular, the ear-hook component 20 may be a fully flexible structure 21 to provide greater wearing comfort for the ear-hook component 20; further, in order to improve the connection stability between the ear-hanging component 20 and the bin body component 10, the shore hardness of the portion where the ear-hanging component 20 is connected with the bin body component 10 may be higher than that of the other flexible structure 21, that is, the other portion of the ear-hanging component 20 except the portion where the ear-hanging component 10 is connected with the bin body component 10 is the flexible structure 21, so that the ear-hanging component 20 can be stably connected with the bin body component 10, and the portion contacting with the ear 200 is the flexible structure 21, and wearing comfort can be improved.

Specifically, in the wearing state, the flexible structure 21 extends from the front side of the ear 200 to the rear side of the ear 200 along the outer contour of the ear 200, so that the flexible structure 21 is hung between the rear side of the ear 200 and the head; further, to improve the wearing stability of the earphone 100, at least one contact point exists on the rear side or the head of the ear 200 of the flexible structure 21, so that the flexible structure 21 has a static friction force effect with the ear 200 or the head; meanwhile, the contact part of the flexible structure 21 and the ear 200 and/or the head is a rough surface, so that the friction acting force between the flexible structure 21 and the ear 200 or the head is improved, the wearing stability of the earphone 100 is improved, and the earphone 100 is prevented from shaking or falling off from the ear 200 in the wearing state.

The curvature of the ear-hook component 20B in fig. 4 (B) gradually decreases from the connecting end a to the free end B to match the shape of the outer contour of the ear 200, and the overall curvature of the ear-hook component 20B is smaller than the overall curvature of the ear-hook component 20a in fig. 4 (a) to fit a larger ear-type user; meanwhile, the lateral dimension of the ear-hook component 20b is larger, so that the ear-hook component 20b is wider in the lateral direction, and the ear-hook component is applicable to ear types with larger lateral dimensions of the ear 200. In other embodiments, the ear-hook assembly 20 may be further sized in the vertical direction to provide more ear-hook assemblies 20 that can accommodate more ears; in addition, the front end portion of the ear hook assembly 20 can be provided to extend from the front side of the ear portion 200 along the outer contour of the ear portion 200 to a corresponding dimension on the rear side of the ear portion 200, so that the ear hook dimension adaptable to different thicknesses of the ear portion 200 can be obtained.
