Description

Technical Field

[0001] This application relates to the field of headphone technology, specifically to a headphone and headphone assembly. Background Technology

[0002] Clip-on headphones typically have a sound-producing part, a first clamping part connected to the sound-producing part, and a second clamping part rotatably connected to the first clamping part. When wearing the headphones, the user can rotate the first or second clamping part to clamp the ear between the first and second clamping parts to secure the headphones. After removing the headphones, the user can rotate the first or second clamping part to a retracted position. However, in the retracted position, the structural strength of the headphones is still insufficient, and they are prone to deformation after being squeezed or bumped. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the related technologies, the present application provides an earphone and an earphone assembly, which can improve the overall structural strength of the earphone and help reduce the probability of deformation of the earphone after being squeezed or bumped.

[0004] To solve the above-mentioned technical problems, in a first aspect, embodiments of this application provide an earphone, including a sound-emitting part, a first clamping part, and a second clamping part. The sound-emitting part has a sound outlet and is located on the first clamping part. The first clamping part is arc-shaped. The second clamping part is rotatably connected to the first clamping part and is also arc-shaped. The radius of the circle containing the first clamping part is equal to the radius of the circle containing the second clamping part, so that when the first clamping part and the second clamping part rotate relative to each other to a retracted state, the first clamping part and the second clamping part together form a partial arc of the same circle.

[0005] With the above configuration, when the earphone is in the storage state, the first clamping part and the second clamping part are in an arc shape. The arc shape has a strong load-bearing capacity, which can improve the overall structural strength of the earphone and the connection strength at the rotating connection between the first clamping part and the second clamping part. This helps to reduce the probability of the earphone deforming after being squeezed or bumped, and also helps to reduce the probability that the first clamping part and the second clamping part cannot rotate normally to change the shape of the earphone.

[0006] Furthermore, the arc-shaped first and second clamping parts easily adapt to the shape of the user's ear, allowing the headphones to be worn comfortably and stably in the user's ear.

[0007] Optionally, the sound-emitting part is located at the first end of the first clamping part, and the second end of the first clamping part is rotatably connected to the first end of the second clamping part so that the earphone can switch between a storage state and a wearing state. When the earphone is in the storage state, the distance between the second end of the second clamping part and the sound-emitting part is a first distance. When the earphone is in the wearing state, the distance between the second end of the second clamping part and the sound-emitting part is a second distance, and the second distance is smaller than the first distance.

[0008] With the above settings, when the headphones are in the wearing state, the space between the first clamping part and the second clamping part can be adapted to the user's ear. Both the first clamping part and the second clamping part can fit snugly against the user's ear and be firmly clamped to the user's ear, so that the headphones can be worn comfortably and stably in the user's ear, and prevent the headphones from loosening or falling off due to vibration, bumps or other factors during the user's exercise.

[0009] Optionally, the second spacing is within the range of 1mm-5mm. With the above settings, when the headphones are in the stored state, the spacing between the second end of the second clamp and the sound-emitting part can be adapted to the user's ear, allowing the headphones to be worn comfortably and stably in the user's ear.

[0010] Optionally, during the switching between the earphone's stored state and the wearing state, the angular displacement of the second clamping part is within the range of 60° to 120°.

[0011] With the above configuration, the first clamping part and the second clamping part are clamped at different positions on the user's ear, and the first clamping part and the second clamping part can also be adapted to and clamped on ears of different shapes or sizes.

[0012] Optionally, the sum of the lengths of the first clamping part and the second clamping part is less than or equal to half the circumference of the circle in which the first clamping part is located, and greater than or equal to one-quarter of the circumference of the circle in which the first clamping part is located.

[0013] With the above settings, the overall length of the first clamping part and the second clamping part can be easily adapted to the size of the user's ear, so that the earphone can be worn comfortably and stably in the user's ear.

[0014] Optionally, the length of the first clamping part is equal to the length of the second clamping part. With the above configuration, the length dimensions of both the first and second clamping parts are easily adapted to the size of the user's ear, allowing the earphone to be worn comfortably and stably in the user's ear.

[0015] Optionally, the rotation axis of the second clamping part is parallel to the central axis of the circle containing the first clamping part. With the above arrangement, the second clamping part and the first clamping part can rotate relative to each other and clamp onto the user's ear.

[0016] Optionally, the sound-emitting part is spherical, with a diameter ranging from 10 mm to 18 mm; or, the sound-emitting part is cylindrical, with a bottom diameter ranging from 10 mm to 18 mm.

[0017] With the above settings, the shape of the sound-emitting part can easily adapt to the shape of the user's ear, and can be worn more stably in the user's ear canal. At the same time, it can avoid the sound-emitting part pressing on the user's ear, avoid discomfort after the user wears the headphones for a long time, and help improve the wearing comfort of the headphones.

[0018] Optionally, the length of the first clamping part is in the range of 12.5mm to 20mm, the length of the second clamping part is in the range of 12.5mm to 20mm, and the sum of the lengths of the first clamping part and the second clamping part is in the range of 25mm to 40mm.

[0019] With the above settings, the length of the first clamping part, the length of the second clamping part, and the overall length of the first clamping part and the second clamping part can be easily adapted to the size of the user's ear, so that the earphone can be worn comfortably and stably in the user's ear.

[0020] Secondly, embodiments of this application also provide an earphone assembly, including an earphone case and earphones as described above. The earphone case has a storage space, and the earphones include a first earphone and a second earphone. When the first earphone and the second earphone are located in the storage space, both the first earphone and the second earphone are in a stored state.

[0021] With the above configuration, one of the first and second earphones can be worn on the user's left ear, and the other can be worn on the user's right ear. When the first and second earphones are in the storage space, both earphones are in a stored state, which helps to reduce the probability of the first and second earphones being damaged by squeezing or bumping in the earphone case.

[0022] Optionally, when both the first and second earphones are in the retracted state, they together form a complete circle. This arrangement improves the appearance of the earphones and earphone components.

[0023] The earphone in this embodiment has a sound outlet in its sound-emitting part, which is located in a first clamping part. The first clamping part is arc-shaped, and a second clamping part is rotatably connected to the first clamping part and is also arc-shaped. The radius of the circle containing the first clamping part is equal to the radius of the circle containing the second clamping part, so that when the first and second clamping parts are rotated relative to each other to a retracted state, the first and second clamping parts together form a partial arc of the same circle. The arc shape has a strong load-bearing capacity, thereby improving the overall structural strength of the earphone and the connection strength at the rotatable connection between the first and second clamping parts. This helps reduce the probability of deformation of the earphone after being squeezed or bumped, and also helps reduce the probability that the first and second clamping parts cannot rotate normally to change the shape of the earphone. Furthermore, the arc-shaped first and second clamping parts easily adapt to the shape of the user's ear, allowing the earphone to be worn more comfortably and stably in the user's ear.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all possible embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0034] As used herein, terms such as “equal,” “parallel,” and “perpendicular” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equal items less than or equal to 5% of either one.

[0035] In the embodiments of this application, the directional indications used to explain the structure and movement of different components, such as up, down, left, right, front, and back, are relative. These indications are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, these directional indications will also change accordingly.

[0036] Please refer to Figure 1 This application provides an earphone 100 and an earphone assembly. The earphone 100 includes a sound-emitting part 110, a first clamping part 120, and a second clamping part 130. The sound-emitting part 110 has a sound outlet 111 and is disposed on the first clamping part 120. The first clamping part 120 is arc-shaped. The second clamping part 130 is rotatably connected to the first clamping part 120 and is also arc-shaped. The radius of the circle containing the first clamping part 120 is equal to the radius of the circle containing the second clamping part 130, so that the first clamping part 120 and the second clamping part 130 are in contact. When rotated to the retracted state, the first clamping part 120 and the second clamping part 130 together form a partial arc of the same circle. This arc shape has a strong load-bearing capacity, thereby improving the overall structural strength of the earphone 100 and the connection strength at the rotational joint between the first clamping part 120 and the second clamping part 130. This helps reduce the probability of deformation of the earphone 100 after being squeezed or bumped, and also reduces the probability of the first clamping part 120 and the second clamping part 130 failing to rotate normally to change the shape of the earphone 100. Furthermore, the arc-shaped first clamping part 120 and the second clamping part 130 easily adapt to the shape of the user's ear 200, allowing the earphone 100 to be worn comfortably and stably in the user's ear 200.

[0037] The headphone assembly of this application embodiment includes a charging case and headphones 100. The charging case has a storage space for storing the headphones 100 and protecting them. Figure 2 As shown, the earphone 100 can also be removed from the storage space and worn on the user's ear 200. Here, Figure 2The grid lines are only used to indicate human body structures such as the user's ear 200. This application embodiment does not limit the specific structure and shape of the earphone case, as long as it has a storage space that can accommodate and store the earphones 100.

[0038] Please combine Figure 1 and Figure 2 The earphone 100 includes a sound-emitting part 110, a first clamping part 120 connected to the sound-emitting part 110, and a second clamping part 130 connected to the first clamping part 120. The first clamping part 120 and the second clamping part 130 can clamp onto the user's auricle 210 to wear the earphone 100 in the user's ear 200. At the same time, at least a portion of the sound-emitting part 110 can enter the user's ear canal 220 and be used to play audio.

[0039] In one example, the sound-emitting part 110 can be spherical or nearly spherical, and its diameter can be in the range of 10mm to 18mm. In another example, the sound-emitting part 110 can be cylindrical or nearly cylindrical, and its base diameter and height can both be in the range of 10mm to 18mm. With these designs, the shape and size of the sound-emitting part 110 easily adapt to the shape and size of the user's ear 200, allowing it to be worn relatively stably within the user's ear canal 220. This also prevents the sound-emitting part 110 from compressing the user's ear 200, thus avoiding discomfort after prolonged use of the headphones 100 and improving the wearing comfort of the headphones 100.

[0040] The sound-emitting section 110 has a housing cavity for housing electronic components such as a circuit board, speaker unit, microphone, or battery. The circuit board houses a controller, which may include at least one of the following: a central processing unit (CPU), a system-on-chip (SOC), an application-specific integrated circuit (ASIC), or a digital signal processor (DSP). The earphone 100 can establish a Bluetooth connection with at least one electronic device such as a mobile phone, computer, or smartwatch via the controller and receive digital audio signals from the electronic device.

[0041] The speaker unit is electrically connected to the controller. The controller can convert digital audio signals received from the electronic device into analog signals and transmit the analog signals to the speaker unit. The speaker unit is used to receive the analog signals and convert them into audio for output. Accordingly, the earphone 100 in this embodiment is a Bluetooth earphone. For example, the earphone 100 in this embodiment can be a true wireless stereo (TWS) earphone.

[0042] In one example, the speaker unit may include a dynamic driver, and correspondingly, the earphone 100 may be a dynamic earphone; in another example, the speaker unit may include a balanced armature driver, and correspondingly, the earphone 100 may be a balanced armature earphone; in yet another example, the speaker unit may also include a piezoelectric driver, and correspondingly, the earphone 100 may be a piezoelectric earphone. In the above examples, there may be multiple speaker units, and each speaker unit may be a dynamic driver, a balanced armature driver, or a piezoelectric driver. For example, in an example where the speaker unit includes at least one dynamic driver and at least one balanced armature driver, the earphone 100 may be a hybrid earphone.

[0043] The sound-emitting part 110 is provided with a sound outlet 111, which communicates with the accommodating cavity. The speaker unit can transmit audio to the outside of the sound-emitting part 110 through the sound outlet 111 to realize the audio playback function. This application does not limit the number of sound outlets 111. For example, there may be one sound outlet 111, or there may be multiple sound outlets 111. This application also does not limit the shape of the sound outlet 111. For example, the sound outlet 111 may be at least one of the following shapes: annular, circular, or rectangular.

[0044] In one example, please combine Figure 1 and Figure 3 A sound outlet 111 is provided, and the sound outlet 111 is annular. The sound outlet 111 surrounds the sound-emitting part 110 and extends circumferentially along the sound-emitting part 110. In an example where the sound-emitting part 110 is spherical or nearly spherical, the central axis of the sound outlet 111 may be collinear with the central axis of the sound-emitting part 110.

[0045] With the above settings, the sound-emitting part 110 can transmit audio in different directions through the sound outlet 111, which helps to improve the sound effect of the headphones 100.

[0046] In other examples, multiple sound outlets 111 may be provided, and the multiple sound outlets 111 may be spaced apart around the sound-emitting part 110. For example, in an example where the sound-emitting part 110 is spherical or nearly spherical, the multiple sound outlets 111 may be spaced apart along a straight line containing the diameter of the sound-emitting part 110. Alternatively, in an example where the sound-emitting part 110 is cylindrical or nearly cylindrical, the multiple sound outlets 111 may be spaced apart around the central axis of the sound-emitting part 110.

[0047] Please continue to refer to Figure 1 and Figure 3 The sound-emitting part 110 is also provided with a sound vent 112, which communicates with the accommodating cavity and is used to regulate the air pressure inside the accommodating cavity to ensure the sound effect of the earphone 100. This application does not limit the number of sound vents 112; for example, there may be one sound vent 112, or there may be multiple sound vents 112. This application also does not limit the shape of the sound vent 112; for example, the sound vent 112 may be at least one of the following shapes: annular, circular, or rectangular.

[0048] In one example, two sound vents 112 are provided, and the sound vents 112 are arranged in a strip shape. One of the two sound vents 112 can be provided on one side of the sound-emitting part 110 and the first clamping part 120, and the other of the two sound vents 112 can be provided on the other side of the sound-emitting part 110 and the first clamping part 120.

[0049] Of course, in other examples, the number of sound vents 112 can be set to other numbers, and is not limited to two; the sound vents 112 can also be set to other shapes, and is not limited to strips.

[0050] The microphone is electrically connected to the controller and can be used to collect human voice for call functionality. The microphone can also be used to collect ambient sound to assist the controller in noise reduction.

[0051] The battery can be electrically connected to the circuit board, controller, speaker unit, and microphone, and provide them with power. When the earphone 100 is stored in the earphone case, the earphone case can be electrically connected to the earphone 100 and charge the battery of the earphone 100.

[0052] Please combine Figure 1 and Figure 4 The second clamping part 130 is rotatably connected to the first clamping part 120. For example, in an example where the sound-emitting part 110 is cylindrical or approximately cylindrical, the rotation axis (hereinafter referred to as "rotation axis") of the first clamping part 120 and the second clamping part 130 may be perpendicular to the central axis of the sound-emitting part 110.

[0053] The second clamping part 130 is used to rotate relative to the first clamping part 120 to clamp the user's auricle 210 between the first clamping part 120 and the second clamping part 130, thereby placing the earphone 100 on the user's ear 200. At this time, as Figure 2 and Figure 4 As shown, the earphone 100 can be worn. The second clamping part 130 is also used to rotate relative to the first clamping part 120 so that the earphone 100 fits into the storage space of the earphone case and can be stored inside the earphone case. At this time, as Figure 1 As shown, the earphone 100 can be in a retracted state. During the rotation of the second clamping part 130 relative to the first clamping part 120, the earphone 100 switches between a retracted state and a wearing state. Based on the above configuration, the first clamping part 120 and the second clamping part 130 can adapt to the ears 200 of different users. Users can rotate the second clamping part 130 to a suitable position according to the shape and size of their ears 200 and their wearing needs, improving the wearing effect and user experience. Furthermore, the earphone 100 can be clamped to the user's ear 200 without the need for any other devices.

[0054] The embodiment of this application uses a rotatable connection between the first clamping part 120 and the second clamping part 130, which improves the convenience and user experience of the earphone 100. Without limitation, for example, the first clamping part 120 and the second clamping part 130 can be rotatably connected via at least one of a pivot or a hinge.

[0055] In some implementations, the pivot can provide frictional damping between the first clamping portion 120 and the second clamping portion 130. For example, the earphone 100 may also include a washer that can be fitted onto the pivot and contact at least one of the first clamping portion 120 or the second clamping portion 130. Alternatively, damping grease may be filled at the connection between the pivot and at least one of the first clamping portion 120 or the second clamping portion 130.

[0056] Therefore, the second clamping part 130 can rotate relatively stably relative to the first clamping part 120, making it easier for the user to control the rotation speed and angle of the second clamping part 130. Furthermore, the second clamping part 130 is not easily loosened after rotating to any position relative to the first clamping part 120, allowing the earphone 100 to be worn relatively securely on the user's ear 200.

[0057] In some implementations, the rotating shaft can be a segmented shaft, correspondingly comprising at least two interconnected components that can rotate relative to each other. For example, in an example where the rotating shaft comprises two components, it may include a first rotating part and a second rotating part connected to each other, with the first rotating part rotating relative to the second rotating part. The first rotating part is connected to the first clamping part 120 and can rotate relative to it, while the second rotating part is connected to the second clamping part 130 and can rotate relative to it. Thus, the second clamping part 130 can rotate relatively flexibly relative to the first clamping part 120, which helps to expand the rotation range of the second clamping part 130 relative to the first clamping part 120, allowing the user to conveniently rotate and adjust the position of either the first clamping part 120 or the second clamping part 130. Of course, the rotating shaft may also include three or more interconnected components that can rotate relative to each other.

[0058] In one embodiment, the first clamping portion 120 may be arc-shaped. That is, the first clamping portion 120 extends along a curve, which is a perfect circle. The diameter of the circle containing the first clamping portion 120 can be in the range of 35mm to 70mm. The length of the first clamping portion 120 can be greater than or equal to one-quarter of the circumference of the circle containing the first clamping portion 120, and can be less than or equal to one-half of the circumference of the circle containing the first clamping portion 120. For example, the length of the first clamping portion 120 can be in the range of 12.5mm to 20mm, specifically 12.5mm, 16mm, or 20mm. Therefore, the arc-shaped first clamping portion 120 easily adapts to the shape and size of the user's ear 200 and avoids pressure on the user's ear 200, thus improving the wearing comfort of the earphone 100.

[0059] In one embodiment, the second clamping portion 130 may also be arc-shaped. That is, the second clamping portion 130 extends along a curve, which is a perfect circle. The diameter of the circle containing the second clamping portion 130 can be in the range of 35mm to 70mm. The length of the second clamping portion 130 can be greater than or equal to one-quarter of the circumference of the circle containing the second clamping portion 130, and can be less than or equal to one-half of the circumference of the circle containing the second clamping portion 130. For example, the length of the second clamping portion 130 can be in the range of 12.5mm to 20mm, and can be 12.5mm, 16mm, or 20mm. Therefore, the arc-shaped second clamping portion 130 easily adapts to the shape and size of the user's ear 200, and can avoid compressing the user's ear 200, thus improving the wearing comfort of the earphone 100.

[0060] In one example, the diameter of the circle containing the second clamping portion 130 can be equal to the diameter of the circle containing the first clamping portion 120, and the length of the second clamping portion 130 can be equal to the length of the first clamping portion 120. For example, the lengths of the first clamping portion 120 and the second clamping portion 130 can both be 12.5mm, 16mm, or 20mm. Correspondingly, the sum of the lengths of the first clamping portion 120 and the second clamping portion 130 can be in the range of 25mm to 40mm. For example, the sum of the lengths of the first clamping portion 120 and the second clamping portion 130 can be 25mm, 32mm, or 40mm. Thus, the overall length of the first clamping portion 120 and the second clamping portion 130 is easily adapted to the size of the user's ear 200, allowing the earphone 100 to be worn comfortably and stably in the user's ear 200.

[0061] Of course, the length of the first clamping part 120 may not be equal to the length of the second clamping part 130. For example, the difference between the length of the first clamping part 120 and the length of the second clamping part 130 may be within a range of ±4mm.

[0062] In an example where the length of the first clamping portion 120 is equal to the length of the second clamping portion 130, the first clamping portion 120 and the second clamping portion 130 are symmetrically disposed on both sides of the pivot or hinge. Accordingly, the pivot or hinge may be located at the center of the entire first clamping portion 120 and the second clamping portion 130. Alternatively, the pivot or hinge may be located near the center of the entire first clamping portion 120 and the second clamping portion 130.

[0063] In some implementations, the axis of rotation can be parallel to the central axis of the circle containing the first clamping part 120. Here, the central axis of the circle containing the first clamping part 120 can be understood as a straight line passing through the center of the circle and perpendicular to its radius. That is, the axis of rotation can be perpendicular to the plane containing the circle containing the first clamping part 120. Of course, the axis of rotation can also be parallel to the central axis of the circle containing the second clamping part 130.

[0064] In an example where the sound-emitting part 110 is cylindrical or approximately cylindrical, the central axis of the sound-emitting part 110 can pass through the center of the circle where the first clamping part 120 is located, and the central axis of the sound-emitting part 110, the circle where the first clamping part 120 is located, and the circle where the second clamping part 130 is located can all be in the same plane.

[0065] In the above embodiment, the sound-emitting part 110 can be provided at the first end of the first clamping part 120, and the second end of the first clamping part 120 can be rotatably connected to the first end of the second clamping part 130 through a pivot or hinge. That is, the second clamping part 130 can rotate around the second end of the first clamping part 120, and the second end of the second clamping part 130 is a free end.

[0066] In one embodiment, when the earphone 100 is in a retracted state, the first clamping portion 120 and the second clamping portion 130 together form a partial arc of a circle. That is, the center of the circle containing the first clamping portion 120 and the center of the circle containing the second clamping portion 130 can coincide. With the above arrangement, when the earphone 100 is in a retracted state, the first clamping portion 120 and the second clamping portion 130 are in an arc shape. The arc shape has a strong load-bearing capacity, thereby improving the overall structural strength of the earphone 100 and the connection strength at the rotational connection between the first clamping portion 120 and the second clamping portion 130. This helps to reduce the probability of the earphone 100 deforming after being squeezed or bumped, and also helps to reduce the probability that the first clamping portion 120 and the second clamping portion 130 cannot rotate normally to change the shape of the earphone 100.

[0067] In the above example, the sum of the length of the first clamping part 120 and the length of the second clamping part 130 can be less than or equal to one-half of the circumference of the circle where the first clamping part 120 is located, and can be greater than or equal to one-quarter of the circumference of the circle where the first clamping part 120 is located.

[0068] In one embodiment, when the earphone 100 is in the retracted state, the distance between the second end (the free end of the second clamping part 130) and the sound-emitting part 110 is a first distance. During the transition between the retracted and worn states of the earphone 100, the distance between the second end of the second clamping part 130 and the sound-emitting part 110 changes. When the earphone 100 is in the worn state, the distance between the second end of the second clamping part 130 and the sound-emitting part 110 is a second distance, which is smaller than the first distance. Based on the above configuration, when the earphone 100 is in the worn state, the space between the first clamping part 120 and the second clamping part 130 can be adapted to the shape of the user's ear 200. Both the first clamping part 120 and the second clamping part 130 can fit snugly against the user's ear 200 and be securely clamped to the user's ear 200, allowing the earphone 100 to be worn comfortably and stably on the user's ear 200, preventing the earphone 100 from loosening or falling off due to vibration, bumps, or other factors during user movement.

[0069] For example, the second spacing can be in the range of 1 mm to 5 mm. For instance, the second spacing can be 2 mm, 3 mm, or 4 mm.

[0070] When wearing the earphone 100, the second clamping part 130 can be rotated to switch the earphone 100 to a retracted state, while the second end of the second clamping part 130 gradually moves away from the sound-emitting part 110. Then, the sound-emitting part 110 is placed in the ear cavity 220, and the second clamping part 130 is rotated again to switch the earphone 100 from the retracted state to the wearing state, while the second end of the second clamping part 130 gradually moves closer to the sound-emitting part 110, until the user's auricle 210 is clamped between the first clamping part 120 and the second clamping part 130. When the earphone 100 is worn on the user's ear 200, the second clamping part 130 can be rotated to switch the earphone 100 to a retracted state, until the second clamping part 130 and the first clamping part 120 no longer clamp the user's auricle 210, so that the earphone 100 can be removed.

[0071] In the above example, during the transition between the stored state and the wearing state of the earphone 100, the angular displacement of the second clamping part 130 is within the range of 60° to 120°. Specifically, this can be understood as follows: when the earphone 100 is in the stored state, the line connecting the second end of the second clamping part 130 and the second end of the first clamping part 120 is a first straight line. During the transition of the earphone 100 from the stored state to the wearing state, the position of the second end of the first clamping part 120 remains unchanged, while the second end of the second clamping part 130 moves relative to the second end of the first clamping part 120. When the earphone 100 is in the wearing state, the line connecting the second end of the second clamping part 130 and the first end of the first clamping part 120 is a second straight line. The first straight line intersects the second straight line, and the angle between the first straight line and the second straight line can be within the range of 60° to 120°.

[0072] Based on the above configuration, the first clamping part 120 and the second clamping part 130 can be clamped at different positions on the user's ear 200, and the first clamping part 120 and the second clamping part 130 can also be adapted to and clamped on ears 200 of different shapes or sizes.

[0073] Please refer to Figure 5 In the above embodiments, there may be one earphone 100, which can be worn on the user's left or right ear. Alternatively, there may be two earphones 100, for example, the earphone 100 may include a first earphone 100a and a second earphone 100b, one of which can be worn on the user's left ear and the other on the user's right ear.

[0074] The first earphone 100a and the second earphone 100b can both be stored in the storage space of the earphone case. When the first earphone 100a and the second earphone 100b are in the storage space, the first earphone 100a and the second earphone 100b are in the storage state, which helps to reduce the probability of the first earphone 100a and the second earphone 100b being damaged by squeezing or bumping in the earphone case.

[0075] In one embodiment, the radius of the circle containing the first clamping portion 120 and the second clamping portion 130 of the first earphone 100a is equal to the radius of the circle containing the first clamping portion 120 and the second clamping portion 130 of the second earphone 100b. The length of the first earphone 100a is equal to the length of the second earphone 100b, and both are half the circumference of the circle containing the first clamping portion 120 of the first earphone 100a. Based on this structure, when both the first earphone 100a and the second earphone 100b are in a retracted state, they can together form a complete circle. This improves the appearance of the earphones 100 and the earphone assembly.
