[0002] Bluetooth earphone products have become increasingly mature, and have rapidly differentiated into various submarkets. The clip-on earphone is one of the common types of Bluetooth earphones. At present, there are mainly three forms of clip-on earphone implementation: one is through elastic deformation of soft glue, two is through elastic deformation of a combination of memory metal and soft glue, and three is through micro-deformation of hard glue. When the above three forms of earphones are worn, both hands are needed to spread the earphones or a single hand is needed to increase the opening of the earphones. A certain time cost is needed when the earphones are worn, because the earphones need to be adjusted to the appropriate size through feeling. The user is inconvenient to wear the earphones, and the wearing error is high. SUMMARY

[0003] The purpose of the embodiment of the present application is to provide a clip-on earphone which can solve the above problems existing in the prior art, and specifically solve the inconvenience of wearing the clip-on earphone and reduce the wearing error.

[0004] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0005] On the one hand, a clip-on earphone is provided, comprising two earphone parts, a connecting part and a metal spring piece. The two earphone parts are connected to the two ends of the connecting part, the metal spring piece is inserted into the connecting part, the two ends of the metal spring piece respectively extend towards the two earphone parts and are correspondingly inserted into the two earphone parts, the metal spring piece has two states of static straightening and static bending, the metal spring piece has at least two trigger points, pressing one of the trigger points can trigger the metal spring piece to deform to the static straightening state, thereby driving the two earphone parts to move towards each other to form a clip ear position capable of being clamped on the ear; pressing the other trigger point can trigger the metal spring piece to deform from the static straightening state to the static bending state, thereby driving the two earphone parts to move in opposite directions, and then enabling the clip-on earphone to be removed from the ear.

[0006] Optionally, the clip ear position is in the shape of a C, the maximum horizontal distance of the clip ear position is L, and the minimum horizontal distance is W1, wherein 3.5<=L / W1<=4.

[0007] Optionally, 2mm<=W1<=4mm, and 8mm<=L<=14mm.

[0008] Optionally, when the metal spring piece deforms to the static bending state, the distance between the opposite lower ends of the two earphone parts is W2, wherein 3.5mm<=W2<=13mm.

[0009] Optionally, the metal elastic sheet is in a straight line shape as a whole when the metal elastic sheet is in the static straightened state, and the cross section of the metal elastic sheet is arc-shaped.

[0010] Optionally, the metal elastic sheet is in a V-shaped state when the metal elastic sheet is in the static bent state, and the cross section of the metal elastic sheet is rectangular or arc-shaped.

[0011] Optionally, the metal elastic sheet has three trigger points, a first trigger point in the middle and a second trigger point symmetrically arranged on both sides of the first trigger point, when the first trigger point is pressed, the metal elastic sheet is deformed from the static straightened state to the static bent state, and when the two trigger points are pressed, the metal elastic sheet is deformed from the static bent state to the static straightened state.

[0014] Optionally, the inside of the earphone part clamped on the inside of the ear is provided with a loudspeaker, and the outer surface of the earphone part towards the ear is provided with a sound outlet corresponding to the loudspeaker.

[0015] The beneficial effects of the present application are as follows: when the earphone needs to be worn, the corresponding trigger point on the metal elastic sheet is first pressed to deform the metal elastic sheet to the static bent state, in which state the metal elastic sheet drives the two opposite earphone parts to move away from each other, so that the ear clamping position originally capable of clamping the ear is enlarged, at this time the earphone can be easily placed on the contour of the ear, and then another trigger point on the metal elastic sheet is pressed to drive the metal elastic sheet to deform from the static bent state to the static straightened state, the metal elastic sheet synchronously drives the two earphone parts to move towards each other, and the ear clamping position is formed between the two earphone parts to clamp the ear, thereby completing the clamping type wearing of the earphone.

[0032] Embodiment one: a clip-on earphone.

[0033] As shown in Figures 1-11 The present embodiment provides a clip-on earphone, which comprises two earphone parts 1, a connecting part 2 and a metal spring 3. The connecting part 2 is located in the middle of the two earphone parts 1, and the top ends of the opposite sides of the two earphone parts 1 are respectively connected to the two ends of the connecting part 2. The middle part of the metal spring 3 is inserted into the connecting part 2, and the two ends of the metal spring 3 respectively extend towards the two earphone parts 1 and are correspondingly inserted into the two earphone parts 1. The metal spring 3 has two states of static straightening and static bending. The metal spring 3 has at least two trigger points. Pressing one of the trigger points can trigger the metal spring 3 to deform to the static straightening state, thereby driving the two earphone parts 1 to move towards each other to form a clamping position 4 that can be clamped on the ear. Pressing the other trigger point can trigger the metal spring 3 to deform from the static straightening state to the static bending state, thereby driving the two earphone parts 1 to move in opposite directions, and then enabling the clip-on earphone to be removed from the ear.

[0034] Based on the above scheme, two earphone parts 1 are connected at both ends of the connecting part 2 to form the overall appearance of the earphone, and the metal spring 3 is built into the earphone part 1 and the connecting part 2. When the metal spring 3 is elastically deformed, it can synchronously drive the two earphone parts 1 to move, so as to realize the free switching of the earphone in the wearing and disengaging states. In the normal state, the metal spring 3 is in the static straight state, and the part of the metal spring 3 located in the two earphone parts 1 is also straight. Since the top 101 of the earphone part 1 corresponding to the metal spring 3 is also flat, when the metal spring 3 is in the static straight state, the two earphone parts 1 are in a natural clamping state, and the clamping position 4 between the two earphone parts 1 can be clamped on the ear. In this state, on the one hand, it can be stably clamped on the ear, and on the other hand, it can be better stored and does not occupy space. If the earphone needs to be taken out from the storage position and worn on the ear, since the two earphone parts 1 are in a clamping state, they cannot be clamped from the outside of the ear to the ear, so at this time, the metal spring 3 needs to be deformed to drive the two earphone parts 1 to open outward, that is, to extend and unfold outward of the clamping position 4. When the metal spring 3 is deformed to the static bending state, it means that the two earphone parts 1 are opened to the maximum. At this time, the distance between the two earphone parts 1 is much larger than that in the clamping position 4, and it can be easily placed on the ear. It should be noted here that it is only placed on the ear, and it cannot be clamped in this state. If the earphone needs to be stably clamped on the ear, the metal spring 3 needs to be deformed again from the static bending state to the static straight state, and simultaneously drive the two earphone parts 1 to move inward. When the metal spring 3 is completely in the static straight state, the clamping position 4 between the two earphone parts 1 is formed, which can be stably clamped on the ear. One earphone part 1 is clamped on the outside of the ear, and the other earphone part 1 is clamped on the inside of the ear. The important point in this scheme is that in the process of deformation of the metal spring 3, unlike the deformation of traditional soft glue or metal or hard glue, in this scheme, the metal spring 3 is triggered to deform by touching or pressing the trigger point. In simple terms, two trigger points are provided on the metal spring 3, similar to the design of a switch. When the user presses one of the trigger points with his finger, the metal spring 3 can automatically switch to the corresponding deformed state. Here, the deformation of the metal spring 3 is automatic, that is, after pressing the trigger point, external force is not needed to drive the deformation of the metal spring 3. The metal spring 3 can automatically switch the mode and drive the movement of the two earphone parts 1.Specifically, since the metal spring 3 is built in the connecting part 2 and the two earphone parts 1, the pressing of the trigger point of the metal spring 3 can be realized by pressing the connecting part 2 or the earphone part 1, such as setting two trigger points on the connecting part 2 and one of the earphone parts 1 respectively, when pressing the connecting part 2, the metal spring 3 can be triggered to automatically deform to the static bending state, when pressing the earphone part 1, the metal spring 3 can be triggered to automatically deform to the static straightening state, but it should be noted that when the metal spring 3 is in the static bending state, repeatedly pressing the connecting part 2 will not change the state of the metal spring 3, and when the metal spring 3 is in the static straightening state, repeatedly pressing the earphone part 1 will not change the state, in short, the pressing trigger point triggers the deformation, which is a single-point one-way deformation, and cannot be continuously deformed on the basis of one deformation, which is also to effectively adapt to the design of the ear-holding earphone and prolong the effectiveness of the elastic deformation of the metal spring 3.

[0035] It should be particularly pointed out that the built-in metal spring 3 needs to have two states of static straightening and static bending, the principle is that the material itself has elasticity and at the same time has two structural states of bending and straightening, the two structural states are mutually constrained and in a balanced state, when the external force breaks this balance, the two states of straightening and bending can be switched with each other, which is similar to the playing method of a clicker.

[0036] Specifically, the metal spring 3 can be made of spring steel, which is a kind of steel specially used for manufacturing springs and elastic elements due to its elasticity in the quenched and tempered state. The elasticity of the steel depends on its ability to elastically deform, that is, within a specified range, the ability of elastic deformation allows it to bear a certain load without permanent deformation after the load is removed. Spring steel has excellent comprehensive performance, such as mechanical properties (especially elastic limit, strength limit, yield ratio), anti-elastic reduction performance (also known as anti-relaxation performance), fatigue performance, hardenability, physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.). In order to meet the above performance requirements, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), precise shape and size, which is particularly suitable for the metal spring 3 in the ear-holding earphone described in the embodiment.

[0037] Preferably, the ear-holding part 4 is C-shaped, and the two earphone parts 1 are also approximately C-shaped, for example, one of the earphone parts 1 is connected to the connecting part 2, as shown in the following figure: Figure 11As shown, the earphone part 1 includes a top part 101, a middle part 102 and a bottom part 103, the top part 101 and the bottom part 103 are respectively connected to the upper and lower ends of the middle part 102, and protrude in the same direction, the length of the top part 101 is greater than the length of the bottom part 103, because the top part 101 needs to be connected with the connecting part 2, and embeds the metal spring 3.

[0038] Based on the scheme that the ear clamping part 4 and the earphone part 1 are both C-shaped, when the metal spring 3 is in a static straightened state, the ear clamping part 4 is formed between the two earphone parts 1, the maximum horizontal distance of the ear clamping part 4 is L, and the minimum horizontal distance is W1, wherein 3.5≤L / W1≤4, as shown in the figure, the maximum horizontal distance here refers to the maximum horizontal distance between the middle parts 102 of the two earphone parts 1, and the minimum horizontal distance refers to the minimum horizontal distance between the bottom parts 103 of the two earphone parts 1, and the two distances need to satisfy a certain multiple relationship, because the maximum horizontal distance L needs to be designed according to the ear width, and the minimum horizontal distance needs to be adjusted according to the ear thickness, there is a certain quantitative relationship between the ear width and the ear thickness, therefore, the multiple between the maximum horizontal distance L and the minimum horizontal distance W1 is set to be between 3.5 and 4, which is more appropriate, only one of the distances needs to be determined to quickly obtain the other distance, which improves the design efficiency and ensures the stability of the ear clamping. Figure 5

[0039] Further, the minimum horizontal distance W1 is in the range of 2mm-4mm, and the maximum horizontal distance L is in the range of 8mm-14mm. When W1 is 2mm, L is 8mm; or when W1 is 4mm, L is 14mm; or when W1 is 3mm, L is 10mm; these parameter values are selected according to the multiple of the maximum horizontal distance and the minimum horizontal distance, which is a response to the conventional parameter setting, when the ear thickness and the ear width do not meet the above multiple relationship, the values of the maximum horizontal distance and the minimum horizontal distance are not limited by the above multiple relationship, for example, when W1 is 2mm, L is 10mm; or when W1 is 4mm, L is 8mm; the parameter setting can be adaptively adjusted according to the actual situation to meet the ear clamping needs of most users.

[0040] At the same time, as shown in the figure, Figure 6 ​As shown, when the metal dome 3 is deformed to a stationary, bent state, the distance between the opposing lower ends of the two earphone parts 1 is W2, that is, the distance between the bottoms 103 of the two earphone parts 1 is W2, where 3.5mm≤W2≤13mm. When the metal dome 3 is in a stationary, bent state, the earphones are open. At this time, the earphone opening, that is, the distance W2, needs to be designed based on the width and thickness of the human ear. When the distance W2 is between 3.5mm and 13mm, the earphones can be well worn in the concha, antihelix, and back of the ear. Specifically, when the distance W2 is 3.5mm, the corresponding W1 is 2mm, and the L is 8mm; or when the distance W2 is 13mm, the corresponding W1 is 4mm, and the L is 14mm. The above-mentioned spacing parameter settings can be summarized and concluded based on the wearing conditions of different users, and then a variety of parameter combinations can be obtained to meet the usage needs of most users, thereby expanding the application scope of the clip-on earphones, ensuring the comfort and stability of the clip-on earphones when worn, while also ensuring the sound quality of the earphones.

[0041] It should be noted that the setting of the above parameters needs to be limited when processing the metal dome 3, because each spacing is achieved based on the deformation of the metal dome 3, that is, the deformation parameters of the metal dome 3 determine the parameters of each spacing during the use of the earphones. Therefore, it is necessary to reasonably design each parameter combination during the processing stage of the metal dome 3 to ensure that it meets the needs of users during use.

[0042] In some embodiments, as Figure 9 、 Figure 10 As shown, when the metal dome 3 is in a static straight state, the metal dome 3 is straight as a whole, and the cross section of the metal dome 3 is arc-shaped; correspondingly, when the metal dome 3 is in a static bent state, the metal dome 3 is V-shaped, and the cross section of the metal dome 3 is rectangular or arc-shaped. When the metal dome 3 is in a static straight state, the whole can be regarded as a straight line, but both sides are bent inward at a certain arc, so that the metal dome 3 forms a groove concave toward the bottom 103 of the earphone part 1. When the metal dome 3 is recentered to the static bent state, it is deformed from a straight line to a V-shape. At this time, the groove of the metal dome 3 will partially disappear or completely disappear, and the upper and lower surfaces of the metal dome 3 are both flat. The design principle of the metal dome 3 can also refer to the design principle of the snap ring. It can be simply understood that by bending the two sides of the metal dome 3 so that it can remain stationary in the straight state, and after the bent part is straightened, the metal dome 3 can remain stationary in the V-shaped state. The specific principle will not be repeated here.

[0043] It is worth mentioning that when the groove of the metal spring 3 is directed towards the top 101 of the earphone part 1, the principle and effect of its use are the same, and the purpose of automatic switching state can be achieved.

[0044] Preferably, the metal spring 3 has three trigger points, a first trigger point in the middle and two second trigger points symmetrically arranged on both sides of the first trigger point. When the first trigger point is pressed, the metal spring 3 is deformed from a static straight state to a static curved state. When the two second trigger points are pressed, the metal spring 3 is deformed from a static curved state to a static straight state. The first trigger point is arranged on the connecting part 2, and the two second trigger points are arranged on the two earphone parts 1. That is, by pressing the connecting part 2, the first trigger point can be triggered, so that the metal spring 3 is deformed into a V shape, and then drives the two earphone parts 1 to open, thereby expanding the opening distance between the two earphone parts 1, so that the earphone can be brought to the position of the concha cavity, the antihelix and the back of the ear. When the earphone is brought, the two earphone parts 1 can be lightly touched, and then the second trigger point is triggered, so that the metal spring 3 is deformed from a V shape to a straight line, and the two earphone parts 1 are relatively folded, so that the earphone returns to the opening closed state, and the concha cavity and the position are clamped, thereby clamping the ear.

[0045] Optionally, the connecting part 2 is a soft rubber sleeve capable of deforming, and the two earphone parts 1 are hard rubber sleeves. Since the metal spring 3 is symmetrically deformed into a V shape with the first trigger point in the middle as the center, the connecting part 2 will also deform correspondingly in this process, so the connecting part 2 is preferably a soft rubber sleeve capable of deforming, which will not interfere with the deformation of the metal spring 3, ensuring that the metal spring 3 can smoothly switch between the two states. The earphone part 1 is used to clamp the ear and the built-in components. In the case of opening and closing by the metal spring 3, the earphone part 1 no longer needs to have the property of elastic deformation, so the earphone part 1 only needs to ensure the safety and stability of the internal components. At the same time, the hard rubber sleeve can also avoid unnecessary elastic deformation of the earphone part 1, which can cause the earphone to deform or accidentally fall off the ear.

[0046] Optionally, the earphone part 1 clamped on the inside of the ear is provided with a loudspeaker inside, and the outer surface of the earphone part 1 towards the ear side is provided with a sound outlet corresponding to the loudspeaker.

[0047] In summary, in the present application, the earphone is automatically opened and closed by driving the earphone part 1 to move by the built-in metal spring 3, and the setting of the distance between each part of the earphone in the open and closed states is matched, and finally the soft rubber sleeve that can deform is matched, which effectively solves the problem that the earphone is not easy to wear. When wearing the earphone, the user only needs to press the soft rubber sleeve to open the earphone, hold the earphone with one hand and place it to the ear contour position, then pinch the earphone part 1 on both sides of the earphone, trigger the deformation switch of the metal spring 3, the earphone opening automatically closes and clamps the ear, which is simple to wear and has low error rate. At the same time, the reasonable size design makes the earphone more comfortable to wear and can clamp the ear well, which can greatly improve the product competitiveness of the earphone in the Bluetooth earphone market.
