Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an ear-clip headphone. Background Art

[0002] Recently, Bluetooth headset products have become increasingly mature and have rapidly differentiated into various market segments. Clip-on earphones are one of the more common types of Bluetooth headsets. At present, there are three main forms of clip-on earphones: one is through elastic deformation of soft glue, the second is elastic deformation through the combination of memory metal and soft glue, and the third is micro-deformation of hard glue. When wearing the above three types of headphones, you need to use both hands to open the headphones or use one hand to enlarge the opening of the headphones. Wearing them requires a certain amount of time because you need to adjust the size of the headphones to fit by feeling. It is not convenient for users to wear them, and it is also easy to make mistakes when wearing them. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide an ear-clip headset, which can solve the above-mentioned problems existing in the prior art, specifically solve the disadvantage that the ear-clip headset is inconvenient to wear, and at the same time reduce the easy wearing error.

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] On the one hand, an ear-clip earphone is provided, comprising: two earphone parts, a connecting part and a metal spring; the two earphone parts are relatively connected to the two ends of the connecting part, the metal spring is inserted in the connecting part, the two ends of the metal spring respectively extend toward the direction of the two earphone parts and are correspondingly inserted in the two earphone parts, the metal spring has two states of static straightening and static bending, and the metal spring has at least two trigger points. Pressing one of the trigger points can trigger the metal spring to deform to the static straightening state, thereby driving the two earphone parts to move toward each other to form an ear-clip position that can be clamped on the ear; pressing the other trigger point can trigger the metal spring to deform from the static straightening state to the static bending state, thereby driving the two earphone parts to move in opposite directions, so that the ear-clip earphone can be removed from the ear.

[0006] Optionally, the ear clamping position is C-shaped, the maximum horizontal spacing of the ear clamping position is L, and the minimum horizontal spacing is W1, wherein 3.5≤L / W1≤4.

[0007] Optionally, 2mm≤W1≤4mm, 8mm≤L≤14mm.

[0008] Optionally, when the metal spring is deformed to a stationary bending state, a distance between the lower ends of the two earphone parts that are opposite to each other is W2, wherein 3.5 mm ≤ W2 ≤ 13 mm.

[0009] Optionally, when the metal spring is in a stationary and straightened state, the metal spring is in a straight line as a whole, and a cross section of the metal spring is in an arc shape.

[0010] Optionally, when the metal spring is in a stationary bending state, the metal spring is V-shaped, and a cross-section of the metal spring is rectangular or arc-shaped.

[0011] Optionally, the metal spring sheet has three trigger points, namely a first trigger point located in the middle and second trigger points located symmetrically on both sides of the first trigger point. When the first trigger point is pressed, the metal spring sheet deforms from a static straight state to a static bent state. When the two trigger points are pressed, the metal spring sheet deforms from a static bent state to a static straight state.

[0012] Optionally, the connecting portion is a soft rubber sleeve that can be deformed.

[0013] Optionally, both earphone parts are hard rubber covers.

[0014] Optionally, a speaker is arranged inside the earphone part clamped on the inner side of the ear, and a sound outlet corresponding to the speaker is opened on the outer surface of the earphone part facing the ear.

[0015] The beneficial effects of the present application are as follows: when it is necessary to wear headphones, first, by pressing the corresponding trigger point on the metal dome, the metal dome is deformed to a static bending state. In this state, the metal dome will drive the two opposite headphone parts to move away from each other, thereby making the ear clamping position that can originally clamp the ear larger. At this time, the headphone can be easily placed on the contour of the ear, and then another trigger point on the metal dome is pressed to drive the metal dome to deform directly from the static bending state to the static straight state. The metal dome simultaneously drives the two headphone parts to move toward each other, and an ear clamping position is formed between the two headphone parts to clamp the ear, thereby completing the ear-clip wearing of the headphone. During the whole process, the shape switching of the headphone only needs to be completed by touching and pressing the trigger point of the metal dome. The action process is simple and effective, and the headphone can be put on and taken off quickly. There is no situation of improper wearing, which completely solves the problem of inconvenient wearing of ear-clip type headphones. In addition, by designing the specific shapes of the metal shrapnel when in different states and limiting and adjusting the optimal wearing parameters between the two earphone parts, the earphones can be more convenient to put on, while ensuring the comfort and tightness of the earphones when worn, thereby improving the user experience of the clip-on earphones.

[0032] Embodiment 1: A clip-on earphone.

[0033] like Figure 1-Figure 11 As shown, this embodiment provides an ear-clip earphone, comprising: 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 two earphone parts 1 on opposite sides are respectively connected to the two ends of the connecting part 2, the middle part of the metal spring 3 is inserted in the connecting part 2, and the two ends of the metal spring 3 are respectively extended toward the direction of the two earphone parts 1 and are correspondingly inserted in the two earphone parts 1, the metal spring 3 has two states of static straightening and static bending, and the metal spring 3 has at least two trigger points, and 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 toward each other to form an ear-clip 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, so that the ear-clip earphone can be removed from the ear.

[0034] Based on the above scheme, the two earphone parts 1 are connected at the two ends of the connecting part 2 to form the overall appearance of the clip-on earphone. The metal shrapnel 3 is built into the earphone part 1 and the connecting part 2. When the metal shrapnel 3 undergoes elastic deformation, it can synchronously drive the earphone parts 1 at both ends to move, so as to realize the free switching of the earphone between the wearing and detaching states. Under normal conditions, the metal dome 3 is in a static and straight state, and the part of the metal dome 3 located inside the two earphone parts 1 is also straight. Since the top 101 of the earphone part 1 where the metal dome 3 is inserted is also straight, when the metal dome 3 is in a static and straight state, the two earphone parts 1 are in a natural clamping state, and an ear clamping position 4 that can be clamped on the ear is formed between the two earphone parts 1. In this state, on the one hand, the earphone can be stably clamped on the ear, and on the other hand, it can be well stored without taking up 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 shape and cannot be clamped on the ear from the outside of the ear, it is necessary to drive the two earphone parts 1 to open outward at the same time through the deformation of the metal dome 3, that is, to clamp. When the outer side of the ear position 4 extends and expands, and the metal spring piece 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 the distance when the ear is clamped at the ear position 4, and it can be easily placed on the ear. It should be noted here that placing it on the ear is just placing it, and it cannot be clamped in this state. If the earphone needs to be stably clamped on the ear, the metal spring piece 3 needs to be deformed again, from the static bending state to the static straight state, and at the same time drive the two earphone parts 1 to move inwardly towards each other. When the metal spring piece 3 is completely in the static straight state, an ear clamping position 4 that can be stably clamped on the ear is formed between the two earphone parts 1, and 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. A relatively important point in this solution is that in the process of deformation of the metal dome 3, unlike the deformation of traditional soft glue or metal or hard glue, the metal dome 3 in this solution is triggered to deform by touching or pressing the trigger point. Simply put, two trigger points are set on the metal dome 3, similar to the design of a switch. When the user presses one of the trigger points with his finger, the metal dome 3 can be triggered to automatically switch to the corresponding deformation state. Here, the deformation of the metal dome 3 is automatic, that is, after pressing the trigger point, there is no need to use external force to drive the deformation of the metal dome 3. The metal dome 3 can automatically switch its shape and drive the two earphone parts 1 to move.Specifically, since the metal spring 3 is built into the connecting part 2 and the two earphone parts 1, pressing the trigger point of the metal spring 3 can be achieved 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 a static bent state. When pressing the earphone part 1, the metal spring 3 can be triggered to automatically deform to a static straight state. However, it should be noted here that when the metal spring 3 is in a static bent state, the state of the metal spring 3 will not change even if the connecting part 2 is pressed repeatedly. When the metal spring 3 is in a static straight state, the state will not change even if the earphone part 1 is pressed repeatedly. In short, the deformation triggered by pressing the trigger point described here is a single-point unidirectional deformation, and will not continue to deform on the basis of one deformation. This is also to effectively adapt to the design of the clip-on earphones, and at the same time to extend the effectiveness of the elastic deformation of the metal spring 3.

[0035] It should be pointed out that the built-in metal dome 3 needs to have two states: static straightening and static bending. The principle is that the material itself has elasticity and has two structural states, bending and straightening. The two structural states constrain each other and are in a state of equilibrium. When the equilibrium state is broken by external force, the two states can be switched between straightening and bending, which is similar to the way of playing with the papa circle.

[0036] The specific metal shrapnel 3 can be made of spring steel material. Spring steel refers to steel specially used for manufacturing springs and elastic elements due to its elasticity in the quenched and tempered state. The elasticity of steel depends on its ability to deform elastically, that is, within a specified range, the ability to deform elastically enables it to withstand a certain load without permanent deformation after the load is removed. Spring steel has excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield strength ratio), anti-elasticity (i.e., anti-elasticity, also known as anti-relaxation performance), fatigue performance, hardenability, and 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 (strictly control surface defects and decarburization), precise shape and size, and is particularly suitable for the metal shrapnel 3 in the clip-on earphone described in this embodiment.

[0037] Preferably, the ear clip 4 is in a C-shape, and the two earphone parts 1 are also approximately in a C-shape. For example, the connection between one of the earphone parts 1 and the connecting part 2 is used as an example. Fig.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 that of the bottom part 103 because the top part 101 needs to be connected to the connecting part 2 and embedded with the metal spring 3.

[0038] Based on the scheme that the ear clamping position 4 and the earphone part 1 are both C-shaped, when the metal spring 3 is in a static and straight state, an ear clamping position 4 is formed between the two earphone parts 1, and the maximum horizontal spacing of the ear clamping position 4 is L, and the minimum horizontal spacing is W1, wherein 3.5≤L / W1≤4, such as Figure 5 As shown, the maximum horizontal spacing mentioned here refers to the maximum horizontal spacing between the middle parts 102 of the two earphone parts 1, and the minimum horizontal spacing is the minimum horizontal spacing between the bottoms 103 of the two earphone parts 1. The two spacings need to satisfy a certain multiple relationship, because the maximum horizontal spacing L needs to be designed according to the ear width, and the minimum horizontal spacing needs to be adjusted according to the ear thickness. There is an inevitable quantitative relationship between the ear width and the ear thickness. Therefore, it is more appropriate to set the multiple between the maximum horizontal spacing L and the minimum horizontal spacing W1 between 3.5 and 4. It is more appropriate to set one of the spacings to quickly obtain the other spacing, which improves the design efficiency and ensures the stability of the ear clip.

[0039] Furthermore, the value range of the minimum horizontal spacing W1 is between 2mm-4mm, and the value range of the maximum horizontal spacing L is between 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 based on the multiples of the maximum horizontal spacing and the minimum horizontal spacing. This is to deal with conventional parameter settings. When the ear thickness and ear width do not meet the above multiple relationship, the maximum horizontal spacing and the minimum horizontal spacing are not limited by the above multiple relationship, such as when W1 is 2mm, L is 10mm; or when W1 is 4mm, L is 8mm; the parameter settings can be adaptively adjusted according to different actual situations to meet the ear clamping needs of most users.

[0040] At the same time, if Figure 6As shown, when the metal spring 3 is deformed to a static bending state, the spacing between the lower ends of the two earphone parts 1 is W2, that is, the spacing between the bottoms 103 of the two earphone parts 1 is W2, wherein 3.5mm≤W2≤13mm. When the metal spring 3 is in a static bending state, the earphone is in an open state. At this time, the opening of the earphone, that is, the spacing W2, needs to be designed according to the width and thickness of the ear of the human ear. When the spacing W2 has a value range of 3.5mm to 13mm, the earphone can be well worn to the concha cavity, the antihelix and the back of the ear. Specifically, the spacing W2 is 3.5mm, the corresponding W1 is 2mm, and the L is 8mm; or the spacing 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 the metal dome 3 is processed, 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 earphone, so 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, Fig. 9 , Fig.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 of it are bent inward by a certain arc, so that the metal dome 3 forms a groove concave toward the bottom 103 of the earphone part 1, and when the metal dome 3 changes its center 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 disappear partially or completely, and the upper and lower surfaces of the metal dome 3 are flat surfaces. The design principle of the metal spring 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 spring 3 so that it can remain stationary in the straight state, and after the bent part is straightened, the metal spring 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 dome 3 faces the top 101 of the earphone part 1, the use principle and effect are the same, and the purpose of automatic switching state can be achieved.

[0044] Preferably, the metal spring sheet 3 has three trigger points, namely, a first trigger point in the middle and second trigger points symmetrically located on both sides of the first trigger point. When the first trigger point is pressed, the metal spring sheet 3 is deformed from a static straight state to a static bent state. When the two trigger points are pressed, the metal spring sheet 3 is deformed from a static bent state to a static straight state. The first trigger point is correspondingly arranged on the connecting portion 2, and the two second trigger points are correspondingly arranged on the two earphone parts 1, that is, by pressing the connecting portion 2, the first trigger point can be triggered, so that the metal spring sheet 3 is deformed into a V shape, and then the two earphone parts 1 are driven to open, and the opening distance between the two earphone parts 1 is expanded, so that the earphone can be worn to the position of the concha cavity, the antihelix and the back of the ear. When the earphone is worn, the earphone parts 1 on both sides can be lightly touched, and then the second trigger point is triggered, so that the metal spring sheet 3 is deformed from a V shape to a straight line, and the two earphone parts 1 are driven to close relatively, so that the earphone returns to the open closed state, clamps the concha cavity and the ear, and thus clamps the ear.

[0045] Optionally, the connecting portion 2 is a soft rubber sleeve that can be deformed, and both 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 point, the connecting portion 2 will also be deformed accordingly in this process, so the connecting portion 2 is preferably a soft rubber sleeve that can be deformed, so as not to interfere with the deformation of the metal spring 3, and ensure that the metal spring 3 can smoothly switch back and forth between the two states; and the earphone part 1 is used to clamp the ear and built-in components. When the opening and closing are achieved 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 its internal components. At the same time, the hard rubber sleeve can also prevent the earphone part 1 from undergoing unnecessary elastic deformation, which may cause the earphone to deform or accidentally fall off the ear.

[0046] Optionally, a speaker is arranged inside the earphone part 1 clamped on the inner side of the ear, and a sound outlet corresponding to the speaker is opened on the outer surface of the earphone part 1 facing the ear.

[0047] To sum up, in the present application, the built-in metal shrapnel 3 is used to drive the earphone part 1 to move to realize automatic opening and closing of the earphone, and the setting of various distances between the earphones in the open and closed states is combined, and finally, the soft rubber cover that can be deformed is combined to effectively solve the problem that the clip-on earphones are difficult to wear. When wearing the earphones, the user only needs to lightly press the soft rubber cover to open the earphones, hold the earphones with one hand and place them to the ear contour position, and then lightly pinch the earphone parts 1 on both sides of the earphone to trigger the deformation switch of the metal shrapnel 3. The earphone opening automatically closes and clamps the ears. It is simple to wear and less prone to error. At the same time, the reasonable size design makes the earphones more comfortable to wear and can clamp the ears well, which can greatly improve the product competitiveness of clip-on earphones in the Bluetooth headset market.
