Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth headsets, in particular to an earclip-type headset and an audio device. Background Art

[0002] Currently, the main forms of existing open earphones are ear-hook type, earclip type and rear-hook type. For the earclip-type earphone, due to its unique form and wearing method, it clamps both sides of the auricle through a simple curved rod connection without using the position of the upper ear root, and will not interfere with ear temple legs, masks, etc. Relatively speaking, it has stronger compatibility for users with different auricle sizes and head circumferences. Therefore, it is a very comfortable earphone for most users. The market also focuses on comfort and stability, and it is not easy to fall off. It is a very suitable earphone form for sports scenarios.

[0003] In the prior art, in order to adapt to the ear thickness of different users, the clamping distance of the current earclip-type earphone depends on the elasticity of the connecting part for passive adjustment. For users with different ear thicknesses, the clamping force cannot be actively adjusted, making it difficult to take into account users with different ear thicknesses and resulting in a poor user experience. In addition, some earclip-type earphones can actively adjust the clamping distance. For example, in an earclip-type earphone with comfortable wearing disclosed in the patent No. CN221283324U, its technical solution is to set a shape memory alloy inside the connecting part to achieve the purpose of adjusting the clamping distance. However, the local fixing force of the shape memory alloy is insufficient, and its wearing stability is general, and the earphone is prone to looseness or falling off during wearing.

[0047] Embodiment 1:

[0048] Please refer to Figures 1 - 8, an embodiment of the present utility model provides an earclip-type earphone 100, which includes a clamping part 110, an earplug part 120 and a connecting part 130. The connecting part 130 is connected between the clamping part 110 and the earplug part 120, and the clamping part 110 and / or the earplug part 120 is rotatably connected to the connecting part 130 to adjust the distance between the clamping part 110 and the earplug part 120. Exemplarily, the clamping part 110, the connecting part 130 and the earplug part 120 are connected in sequence, making the overall shape of the earphone U-shaped. When wearing the earphone, the earplug part 120 and the clamping part 110 respectively abut against the inner and outer sides of the ear, so that the earphone can be clamped on the ear. In this embodiment, both the clamping part 110 and the earplug part 120 are rotatably connected to the connecting part 130, that is to say, both the clamping part 110 and the earplug part 120 can rotate relative to the connecting part 130, and the user can adjust the clamping distance by rotating one of the clamping part 110 and the earplug part 120 or both of them simultaneously.

[0049] Please refer to Figure 1 , Figure 2 , Figure 3 , in this embodiment, for the earclip-type earphone 100 of the present application, since at least one of the clamping part 110 and the earplug part 120 is rotatably connected to the connecting part 130, by providing a rotating body 131 at the end of the connecting part 130, at least one of the earplug part 120 and the clamping part 110 can rotate relative to the connecting part 130, so as to achieve the purpose of actively adjusting the clamping distance, and the connection between the connecting part 130 and the earplug part 120, and the connection between the connecting part 130 and the clamping part 110 are stable, and there is no problem of the earphone loosening or falling off during wearing.

[0050] Please refer to Figure 1 , Figure 2 , Figure 3, in a possible implementation, a rotation groove 1231 is formed in the clamping part 110 and / or the earplug part 120. A rotating body 131 is provided at the end of the connecting part 130. The rotating body 131 is movably arranged in the rotation groove 1231, and an elastic member 140 is arranged between the rotating body 131 and the rotation groove 1231. Exemplarily, the elastic member 140 is made of an elastic material. Arranging the elastic member 140 between the rotating body 131 and the rotation groove 1231 is beneficial to reducing the wear between the rotating body 131 and the rotation groove 1231 during rotation, thereby prolonging the service life of the earphone. The elastic member 140 is fixedly connected to the inner wall of the rotation groove 1231. When the rotating body 131 rotates, it adapts to deformation, and after the rotating body 131 stops rotating, it resumes deformation. Of course, in specific applications, the elastic member 140 can also be fixed on the outer surface of the rotating body 131. In addition, it should be noted that the rotating body 131 being movably arranged in the rotation groove 1231 means that the rotating body 131 can rotate relative to the rotation groove 1231 under the action of an external force, and the rotating body 131 is fixed when the external force is removed. Specifically, when the user pinches the clamping part 110 and then rotates it, the clamping part 110 rotates by a certain angle. After the hand leaves the clamping part 110, the elastic member 140 fixes the rotating body 131 to maintain the rotated posture.

[0051] Please refer to Figure 3 , Figure 4 , Figure 5, in a possible implementation, the elastic member 140 includes an abutting surface layer 141 and a wrapping outer layer 142. The wrapping outer layer 142 is attached to the rotation groove 1231, and the abutting surface layer 141 is disposed between the wrapping outer layer 142 and the rotating body 131. The elastic modulus of the abutting surface layer 141 is greater than that of the wrapping outer layer 142; several protrusions 1311 that abut against the abutting surface layer 141 are convexly provided on the surface of the rotating body 131. Exemplarily, compared with the wrapping outer layer 142 on the outside, the abutting surface layer 141 on the inside is more likely to deform. Since several protrusions 1311 are formed on the surface of the rotating body 131, the abutting surface layer 141 is made of a high-elasticity material, which can further adapt to the protrusions 1311 of the rotating body 131. In this embodiment, the elastic member 140 is fixed to the inner wall of the rotation groove 1231. Therefore, the protrusions 1311 are provided on the outer surface of the rotating body 131. In a specific application, the elastic member 140 can be fixed to the outer surface of the rotating body 131, and the protrusions 1311 are provided on the inner wall of the rotation groove 1231. It can be understood that at this time, the wrapping outer layer 142 is attached to the outer surface of the rotating body 131, and the abutting surface layer 141 is located on the outside. At the same time, the arrangement of the protrusions 1311 can increase the extrusion force and the contact area with the abutting surface layer 141, so that the earplug portion 120 or the clamping portion 110 can remain in the current position after rotation, and its connection is stable, and there will be no problem of the earphone loosening or falling off when wearing the earphone. In addition, it should be noted that the protrusions 1311 in this embodiment are hemispherical structures protruding from the body of the rotating body 131, and several protrusions 1311 are evenly distributed on the outer surface of the body of the rotating body 131. The hemispherical shape is beneficial to the rotation of the rotating body 131 and reduces the wear between the rotating body 131 and the elastic member 140.

[0052] Please refer to Figure 3 , Figure 4 , Figure 5, in a possible implementation, the earclip-type earphone 100 includes a speaker assembly 150 and a power supply assembly 160. The connecting portion 130 extends a connecting wire 132 that is electrically connected to at least one of the speaker assembly 150 and the power supply assembly 160. The connecting wire 132 is arranged in an elastic spiral shape. Exemplarily, the connecting wire 132 is arranged to facilitate elongation when the earplug portion 120 or the clamping portion 110 rotates, preventing the wire connection from loosening due to being pulled. It can be understood that the connecting wire 132 is a structure similar to a spring, and the connecting wire 132 is also a wire 134 or an extension part of the wire 134, and is electrically connected to the electrical components of the earphone. In this embodiment, the connecting wire 132 is arranged at one end connected to the speaker assembly 150, and the other end of the connecting portion 130 is also electrically connected to the power supply assembly 160. Additionally, it should be noted that the connecting portion 130 includes a silicone skin 133 and a wire 134. The connecting wire 132 extends from the end of the wire 134, and the silicone skin 133 wraps the wire 134. The function of the silicone skin 133 is to protect the wire 134 and provide insulation, and the function of the wire 134 is to conduct electricity.

[0053] Please refer to Figure 3 , Figure 4 , Figure 5 , in a possible implementation, the earplug portion 120 includes an upper housing 121, a lower housing 122, and a receiving housing 123. The upper housing 121 and the lower housing 122 are connected to jointly form a receiving space 124. The receiving housing 123 and the speaker assembly 150 are both arranged in the receiving space 124. The connecting portion 130 is connected to the receiving housing 123, and a pressure relief hole 1211 is provided on the upper housing 121. The clamping portion 110 includes a housing 111. The power supply assembly 160 is arranged in the housing 111, and a flexible contact surface 1111 is provided on one side of the housing 111 facing the earplug portion 120. Exemplarily, the upper housing 121 and the lower housing 122 are connected, a part of the connecting portion 130 extends into the receiving space 124, and the rotating body 131 cooperates with the rotating groove 1231 on the receiving housing 123, and the connecting wire 132 passes through the receiving housing 123 and is connected to the speaker assembly 150. That is to say, the rotating groove 1231 of the earplug portion 120 is arranged in the receiving housing 123, and the overall shape of the upper housing 121 and the lower housing 122 after connection is approximately spherical. The flexible contact surface 1111 is made of an elastic material, and the flexible contact surface 1111 is arranged in a curved surface shape that is the same as the contour of the back of the auricle, so as to facilitate the earphone to adaptively clamp the ear, and the flexible material can further prevent the ear from being pinched painfully, improving the user experience. It can be understood that the power supply assembly 160 can be arranged in the clamping portion 110 or in the earplug portion 120. In this embodiment, the power supply assembly 160 is arranged in the clamping portion 110.

[0054] Please refer to Figure 3, in a possible implementation, the clamping portion 110 includes a first magnetic member 112, and the earplug portion 120 includes a second magnetic member 125 that cooperates with the first magnetic member 112. Exemplarily, the first magnetic member 112 and the second magnetic member 125 cooperate. Specifically, the first magnetic member 112 is disposed on the side of the clamping portion 110 that abuts against the ear, and the second magnetic member 125 is disposed on the side of the earplug portion 120 that abuts against the ear. The clamping force is strengthened through the cooperation of the first magnetic member 112 and the second magnetic member 125, further enhancing the stability when the earphone is worn.

[0055] Please refer to Figure 9 、 Figure 10 , in a possible implementation, the first magnetic member 112 is a permanent magnet, a single-wire electromagnet, or a double-wire electromagnet; the second magnetic member 125 is a permanent magnet, a single-wire electromagnet, or a double-wire electromagnet. Exemplarily, for a single-wire electromagnet and a double-wire electromagnet, it is possible to control whether there is a magnetic clamping force between the earplug portion 120 and the clamping portion 110 by controlling whether the wire 134 is energized, and it is also possible to control the magnitude of the clamping force by controlling the magnitude of the current. Specifically, in this embodiment, four solutions are provided. Solution 1: Both the first magnetic member 112 and the second magnetic member 125 are permanent magnets; Solution 2: The first magnetic member 112 is a single-wire electromagnet, and the second magnetic member 125 is a permanent magnet; Solution 3: The first magnetic member 112 is a double-wire electromagnet, and the second magnetic member 125 is a permanent magnet; Solution 4: Both the first magnetic member 112 and the second magnetic member 125 are double-wire electromagnets. The specific structure of the single-wire electromagnet is as Figure 9 shown, and the specific structure of the double-wire electromagnet is as Figure 10 shown. It can be understood that the double-wire electromagnet can switch the positive and negative magnetic poles. In the application of Solution 4, the first magnetic member 112 and the second magnetic member 125 have two states of attraction and repulsion. In the attraction state, the user can adjust the clamping distance by adjusting the magnitude of the current. When the user needs to remove the worn earphone, or when the user's ear is very thick and the rotation of the clamping portion 110 or the earplug portion 120 to adjust the clamping distance still cannot meet the requirement, the first magnetic member 112 and the second magnetic member 125 can be used in a repulsive manner.

[0056] Please refer to Figure 2 and Figure 3 , in a possible implementation, a sound outlet hole 126 is formed on the earplug portion 120. The sound outlet hole 126 is circular, and the ratio of the orthographic projection area of the sound outlet hole 126 to the orthographic projection area of the earplug portion 120 is greater than 0.3. Exemplarily, as Figure 3As shown, the sound output direction is the normal direction of the centroid of the sound output hole interface. The sound output hole 126 is provided on the side away from the connecting portion 130. Considering that the rotation of the earplug portion 120 will cause the change of the sound output direction and the deterioration of the sound listening effect, therefore, in this application, a sound output hole 126 with a large aperture is provided to expand the range of sound coverage and reduce the influence caused by the rotation of the earplug portion 120, ensuring that the earphone of this application can adjust the clamping distance without affecting the sound listening effect. In this embodiment, the ratio of the orthographic projection area of the sound output hole 126 to the orthographic projection area of the earplug portion 120 is 0.3. Of course, in specific applications, this ratio is not limited to this. For example, as an alternative solution, it can also be 0.35, or 0.4, or 0.45, or 0.5, or 0.55, or 0.6, or 0.65, or 0.7, or 0.75, or 0.8, or 0.85, or 0.9, or 0.95, and no more limitations are made here.

[0057] Please refer to Figure 6 、 Figure 7 、 Figure 8 The second object of the present utility model is to provide an audio device 200, including an earphone case 210 and the above-mentioned earclip-type earphone 100. The earphone case 210 includes a box body 211 and a cover body. The cover body is rotatably connected to the box body 211. The box body 211 is formed with a placement slot 2111 for placing the earclip-type earphone 100. The extending directions of the two placement slots 2111 are arranged at a preset inclined angle. Exemplarily, the box body 211 includes a PCBA board 2112, a battery 2113, a thimble 2114 and a bottom case 2115. The PCBA board 2112, the battery 2113 and the thimble 2114 are all arranged in the bottom case 2115. The battery 2113 is electrically connected to the PCBA board 2112, and the thimble 2114 is electrically connected to the PCBA board 2112. And the thimble 2114 partially extends into the placement slot 2111. When the earclip-type earphone 100 of this application is placed in the earphone case 210, the earclip-type earphone 100 contacts the thimble 2114, and at this time, the earphone case 210 can charge the earphone. Specifically, in this embodiment, the preset angle between the extending directions of the two placement slots 2111 is set to 20°. Of course, in specific applications, the angle of the preset angle is not limited to this. For example, as an alternative solution, the angle of the preset angle can also be set to any angle within 15° to 30°, and no more limitations are made here.

[0058] Please refer to Figure 6 、 Figure 7 、 Figure 8 In this embodiment, the extending directions of the two placement slots 2111 in the earphone case 210 are arranged at a preset inclined angle. On the one hand, it ensures that there is enough space for holding between the left and right earphones, facilitating the user to take the earphones. On the other hand, it can also ensure the compact structure of the earphone case 210, so as not to cause too large a volume and inconvenience for the user to carry.

[0059] Example Two:

[0060] Please refer to Figure 11 and Figure 12 . Compared with Example One, the difference in this example lies in the different structure of the abutting surface layer 141. The specific solution is as follows:

[0061] Please refer to Figure 11 and Figure 12 . In a possible implementation, the abutting surface layer 141 is provided with a plurality of elastic protrusions 1411 on the side facing the rotating body 131. Exemplarily, the elastic protrusions 1411 are made of deformable elastic materials, and their shape is similar to the brush structure of a toothbrush head. The plurality of elastic protrusions 1411 are spaced apart in multiple rows and columns. When the protrusion 1311 is limited and enters the abutting surface layer 141, it is fixed and limited by the elastic protrusions 1411, and returns to its original state after leaving the elastic protrusions 1411. The setting of the elastic protrusions 1411 is beneficial to further improving the deformation ability of the abutting surface layer 141, thereby further increasing the contact area with the rotating body 131, enabling the rotating body 131 to deform quickly during rotation, facilitating the user's rotation. After the rotation stops, the elastic protrusions 1411 immediately wrap the protrusion 1311, increasing the stability of its connection, so that the ear insertion part 120 and the clamping part 110 will not loosen easily.

[0062] As shown in Figure 11 , it is a schematic diagram of the position when the protrusion 1311 is at position one 1401. As shown in Figure 12 , it is a schematic diagram of the position when the protrusion 1311 is at position two 1402. When the protrusion 1311 moves from position one 1401 to position two 1402, the elastic protrusions 1411 at position two 1402 can deform. After the user removes the applied external force, the deformed elastic protrusions 1411 can fix the protrusion 1311. At this time, the elastic protrusions 1411 at position one 1401 return to their original state and maintain their original elastic force. When the elastic protrusions 1411 move to position one 1401 again, the elastic protrusions 1411 at position one 1401 can deform to fix the elastic protrusions 1411.

[0063] Except for the above structural differences, the ear clip-type earphone 100 and its components in this example are the same as those in Example One above, and will not be elaborated here.

[0064] Example Three:

[0065] Please refer to Figure 13 . Compared with Example One, the difference in this example lies in the different shape of the sound outlet hole 126. The specific solution is as follows:

[0066] Please refer to Figure 13, an sound outlet hole 126 is formed on the earplug part 120. The sound outlet hole 126 is rectangular. Let the direction in which the earplug part 120 moves relative to the clamping part 110 be the moving direction. In the front projection direction of the earplug part 120, the ratio of the length L of the sound outlet hole 126 along the moving direction to the maximum width of the earplug part 120 is between 0.6 and 0.9. Exemplarily, the sound outlet hole 126 in this embodiment is set to be strip-shaped, and the extending direction of the sound outlet hole 126 is the same as the moving direction when the earplug part 120 rotates. That is to say, when the earplug part 120 rotates, it can still ensure that part of the sound outlet direction is directly facing the ear canal. In this embodiment, the ratio of the length L of the sound outlet hole 126 along the moving direction to the maximum width of the earplug part 120 is 0.7. Of course, in specific applications, this ratio is not limited to this. For example, as an alternative solution, it can also be 0.6, or 0.65, or 0.75, or 0.8, or 0.85, or 0.9. In addition, it should be noted that the above-mentioned moving direction refers to the direction in which the earplug part 120 approaches or moves away from the clamping part 110 when rotating.

[0067] Except for the above structural differences, the earclip-type earphone 100 and its components in this embodiment are the same as those in the first embodiment, and will not be elaborated here.

[0068] Embodiment 4:

[0069] Please refer to Figure 14 、 Figure 15 , compared with the first embodiment, the difference in this embodiment is the shape of the sound outlet hole 126. The specific solution is as follows:

[0070] Please refer to Figure 14 、 Figure 15, a sound outlet hole 126 is formed on the earplug portion 120. The shape of the sound outlet hole 126 is obtained by combining a rectangular hole and a circular hole. Let the direction in which the earplug portion 120 moves relative to the clamping portion 110 be the moving direction. In the front projection direction of the earplug portion 120, the ratio of the length L of the sound outlet hole 126 along the moving direction to the maximum width of the earplug portion 120 is between 0.6 and 0.9. Exemplarily, the solution of this embodiment combines Embodiment 2 and Embodiment 3. The sound outlet hole 126 is set in a combined shape of a circle and a rectangle. In this embodiment, there are two solutions. Solution 1 is to set a circular hole at the center position of the rectangular groove on the basis of Embodiment 2. Solution 2 is to set two circular holes on the rectangular groove on the basis of Embodiment 2. It can be understood that the diameter of the circular hole in Solution 1 and Solution 2 is greater than the short side length of the rectangular groove. Specifically, Embodiment 3 is to add a circular hole design on the basis of Embodiment 2, and set circular holes corresponding to the ear canal at the most conventional position when wearing a general earphone, so as to increase the sound output volume and further improve the sound output effect. In addition, it should be noted that the above-mentioned moving direction refers to the direction in which the earplug portion 120 approaches or moves away from the clamping portion 110 when rotating.

[0071] Except for the above structural differences, the earclip-type earphone 100 and its components in this embodiment are the same as those in Embodiment 1 above, and will not be elaborated here.

[0072] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
