[0035] The ear-hook headphones provided by this utility model, which allow for convenient adjustment of the opening and closing angle, have the following beneficial effects:

[0036] 1. This utility model provides an ear-hook earphone with a convenient adjustable opening angle. By setting the first connecting segment of the elastic connector at one end of the earphone body, and the first ear clip arm sleeved on the transition segment and the second connecting segment, or only on the second connecting segment, the first ear clip arm can adjust the opening angle between itself and the earphone body through the bending deformation of the elastic connector. Users can adjust the size of the opening angle arbitrarily according to their own needs (within a certain angle range). The angle adjustment is flexible and suitable for different ear shapes of different users, which improves the application range. Moreover, it is comfortable to wear, reduces the discomfort of wearing ear-hook earphones, and improves the user experience. The structure is simple and the cost is low.

[0037] 2. The present invention provides an ear-hook type earphone with an adjustable opening angle. The material of the first ear clip arm can be soft rubber. Soft rubber has good flexibility. On the one hand, the ear clip arm can contact the user's auricle, which can reduce the pain caused by wearing earphones. On the other hand, it can increase the friction between the first ear clip arm and the ear, preventing the earphone from falling off.

[0038] 3. The present invention provides an ear-hook type earphone with convenient adjustment of opening and closing angle. The outer side of the transition section is also covered with a flexible tube.

Detailed Implementation

[0048] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0049] To keep the drawings concise, only the parts relevant to this invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0050] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] In one embodiment, see the accompanying drawings. Figures 1 to 6An ear-hook earphone with an adjustable opening angle is described. The first ear clip arm 300 is fitted only on the second connecting section 230 or on the outside of the second connecting section 230 and the transition section 220. The elastic connector 200 bends and drives the first ear clip arm 300 to rotate toward the earphone body 100, thereby realizing the free adjustment of the opening angle between the first ear clip arm 300 and the earphone body 100. This allows the ear-hook earphone to meet the ear shape of different users and improve the user experience.

[0053] Specifically, an ear-hook type earphone with an adjustable opening angle includes an earphone body 100, a first ear clip arm 300, and an elastic connector 200. One end of the earphone body 100 is used to emit sound, and the first ear clip arm 300 is located at the other end of the earphone body 100. The elastic connector 200 includes a first connecting segment 210, a transition segment 220, and a second connecting segment 230, which are connected sequentially. The first connecting segment 210 is connected to the other end of the earphone body 100, and correspondingly, the transition segment 220 and the second connecting segment 230 are located on the outside of the earphone body 100. The first ear clip arm 300 is fitted over the outside of the second connecting segment 230 and the transition segment 220, or it may only be fitted over the outside of the second connecting segment 230.

[0054] The elastic connector 200 is designed to bend, thereby adjusting the opening angle between the first ear clip arm 300 and the headphone body 100. Users can wear the ear-hook headphones by clamping the earlobe between the headphone body 100 and the first ear clip arm 300.

[0055] During use, users can adjust the opening angle between the first ear clip arm 300 and the earphone body 100 by adjusting the bending degree of the elastic connector 200 according to the thickness and shape of their own ear. It is understood that after the elastic connector 200 bends, its elastic deformation allows the first ear clip arm 300 and the earphone body 100 to maintain a certain opening angle for a long time without rebounding. Therefore, users can adjust the opening angle to a suitable size and wear the ear-hook earphones without them easily falling off, making them suitable for complex usage scenarios such as sports. Correspondingly, after use, users can directly remove the ear-hook earphones from their ears.

[0056] Furthermore, the flexibility of the elastic connector 200 is unrestricted (within a certain angle range). Compared to existing headphones on the market, users can freely adjust the opening angle without any limitations, allowing them to find the most suitable size and improving wearing comfort, thus increasing user engagement. Correspondingly, this ear-hook headphone only requires the elastic connector 200 to achieve free adjustment of the opening angle, resulting in a simple structure, easy maintenance, and low cost.

[0057] In one embodiment, the headphone body 100 is further described. Specifically, please refer to the accompanying drawings. Figure 5 The headphone body 100 includes a main body segment 110 and a second ear clip arm 120. The main body segment 110 is disposed at one end of the second ear clip arm 120. Correspondingly, the first connecting segment 210 is connected to the end of the second ear clip arm 120 away from the main body segment 110.

[0058] The main body 110 is used to emit sound. When in use, the user wears the main body 100 of the ear on the front of the auricle, and the first ear clip 300 is located on the back of the auricle. The main body 110 is adapted to fit with the user's concha. Through the cooperation of the first ear clip 300 and the second ear clip 120, the main body 110 is worn on the ear and does not fall off.

[0059] Optionally, the first ear clip arm 300 has a natural state and an ear-clamping state. In the natural state, the main body segment 110 is parallel to the first ear clip arm 300, so that the ear-hook earphone is in a straight, unfolded state, and the extension direction of the first ear clip arm 300 is along the extension direction of the main body segment 110. In the ear-clamping state, the main body segment 110 and the first ear clip arm 300 are set at an angle, and the extension direction of the main body segment 110 is towards the first ear clip arm 300.

[0060] For example, when the elastic connector 200 bends, the first ear clip arm 300 forms an angle with the main body segment 110. By adjusting the range of the angle, the first ear clip arm 300 assists the ear-hook earphone in being better held on the ear. In its natural state, the first ear clip arm 300 is unfolded back to a state parallel to the main body segment 110 to facilitate the storage of the ear-hook earphone.

[0061] In one embodiment, see the accompanying drawings. Figure 3 and Figure 4This embodiment further describes the ear-hook earphone. The first connecting segment 210 is located inside the earphone body 100, specifically inside the end of the second ear clip arm 120 away from the main body segment 110. The first ear clip arm 300 is provided with a receiving cavity 300a. The second connecting segment 230 and the transition segment 220 are disposed in the receiving cavity 300a, and the end of the first ear clip arm 300 near the earphone body 100 is adapted to press against the end of the earphone body 100 near the first ear clip arm 300.

[0062] It is understandable that there are many types of soft rubber, such as polyester resin or PVC rubber. These soft rubber materials have good softness and elasticity. When the elastic connector 200 bends relative to the headphone body 100 at the intersection of the first connecting section 210 and the transition section 220, the end of the first ear clip arm 300 near the headphone body 100 will also undergo a certain deformation, which makes it easier for the user to adjust the opening and closing angle between the first ear clip arm 300 and the headphone body 100.

[0063] In one embodiment, the first ear clip arm 300 is further described. In this embodiment, the first ear clip arm 300 includes a clamping portion 310 and a cover plate 320, and the first ear clip arm 300 is only sleeved on the outside of the second connecting section 230. Accordingly, the clamping portion 310 is made of soft rubber material, and the cover plate 320 is made of hard rubber material. Alternatively, the first ear clip arm 300 may be entirely made of soft rubber. The clamping portion 310 is adapted to contact the back of the user's auricle, and the use of soft rubber material can improve the user's wearing comfort, while the use of hard rubber material for the cover plate 320 can improve the structural strength of the first ear clip arm 300.

[0064] Optionally, the transition segment 220 and / or the second connecting segment 230 are configured to deform and bend to adjust the opening and closing angle of the first ear clip arm 300 and the earphone body 100, so that the earphone body 100 is worn on the auricle. For example, when the transition segment 220 and / or the second connecting segment 230 deform, the first ear clip arm 300, sleeved around the outer periphery of the transition segment 220 and the second connecting segment 230, can deform along with the transition segment 220 and the second connecting segment 230, thereby adjusting the opening and closing angle of the first ear clip arm 300 relative to the earphone body 100. The user can adjust the shape of the transition segment 220 or the second connecting segment 230 individually, or simultaneously. In this way, the shape of the first ear clip arm 300 is more diverse and variable, which is beneficial for wearing on different ear shapes of different users.

[0065] Preferably, the first connecting segment 210 can be straight and directly disposed inside the end of the second ear clip arm 120 away from the main body segment 110, or it can have a certain degree of curvature (similar to corrugation) to improve the local strength of the connection between the first connecting segment 210 and the second ear clip arm 120.

[0066] Of course, the accommodating cavity 300a can be slightly smaller than the elastic connector 200. The first ear clip arm 300 is fitted onto the outside of the second connecting section 230 and the transition section 220 via an interference fit with the elastic connector 200. Correspondingly, the elastic connector 200 and the first ear clip arm 300 can also be connected and fixed together by means of adhesive dispensing or other methods. Furthermore, the first connecting section 210 can be located inside or outside the second ear clip arm 120 to achieve connection with it. These details are not elaborated here, but are all within the protection scope of this utility model.

[0067] In practical production applications, in its natural state, the first ear clip arm 300 of this ear-hook headset can be tilted towards the second ear clip arm 120. When the headset needs to be used, the user simply needs to pry open the first ear clip arm 300 and the second ear clip arm 120, put the headset on the ear, and adjust the opening angle. Correspondingly, after use, the user can pry open the first ear clip arm 300 and the second ear clip arm 120 to remove the headset.

[0068] In one embodiment, the elastic connector 200 is further described. Specifically, the elastic connector 200 can be made of a shape memory alloy, which has good deformation and resilience characteristics. When in a bent state, it has a high clamping force, making the earphone less likely to fall off. Of course, the elastic connector 200 can also be made of other materials, such as steel, copper, titanium alloy, etc., to achieve the purpose of wearing the ear-hook earphone on the ear after bending.

[0069] In one embodiment, this embodiment further describes the situation where the first ear clip arm 300 is only sleeved on the outside of the second connecting section 230, as shown in the accompanying drawings. Figure 3 and Figure 4 The first ear clip arm 300 includes a clamping part 310 and a cover plate 320. Correspondingly, the second connecting segment 230 is connected to one side of the clamping part 310, and the cover plate 320 is disposed on the side of the second connecting segment 230 away from the clamping part 310. In addition, the cover plate 320 is adapted to engage with the clamping part 310, thereby allowing the first ear clip arm 300 to be fitted only onto the second connecting segment 230. In other words, this application protects the elastic connector 200 by using a cover plate 320 made of a relatively hard material, but also considers that the opening and closing angle between the first ear clip arm 300 and the headphone body 100 needs to be adjusted. Therefore, a transition section 220 is provided, and the second connecting segment 230 is disposed inside the first ear clip arm 300. The cover plate 320 and the clamping part 310 clamp the second connecting segment 230 to prevent the second connecting segment 230 from falling out of the first ear clip arm 300.

[0070] Optionally, when the first ear clip arm 300 is only fitted onto the second connecting section 230, the transition section 220 is exposed outside the first ear clip arm 300. The transition section 220 is configured to deform and bend to adjust the opening and closing angle of the first ear clip arm 300 and the earphone body 100, so that the earphone body 100 can be worn on the user's ear. Because the second connecting section 230 has a poor deformation effect when the cover plate 320 engages with the clamping part 310, this application achieves effective adjustment of the opening and closing angle of the first ear clip arm 300 and the earphone body 100 by exposing the transition section 220.

[0071] Optionally, the clamping part 310 has an opening groove 311 at one end near the second ear clamp arm 120. One side of the opening groove 311 coincides with one side of the first ear clamp arm 300 near the second ear clamp arm 120, and the side of the first ear clamp arm 300 near the second ear clamp arm 120 is connected to the outside. Correspondingly, the cover plate 320 includes a cover plate body and a protrusion 321. The protrusion 321 is disposed at one end of the cover plate body and is located on the side of the cover plate body near the clamping part 310. Correspondingly, the second connecting section 230 is connected to one side of the clamping part 310. The protrusion 321 is adapted to engage with the opening groove 311 to fix the second connecting section 230 on the clamping part 310, so that the first ear clamp arm 300 is only sleeved on the outside of the second connecting section 230. In other words, the opening groove 311 has a first opening 311a facing the earphone body 100 and a second opening 311b facing the cover plate 320. The second connecting segment 230 is connected to the opening groove 311 along the first opening 311a, and the protrusion 321 engages with the opening groove 311 along the second opening 311b. Thus, the second connecting segment 230 is held by the protrusion 321 and the clamping part 310, so that the second connecting segment 230 can be securely installed in the first ear clip arm 300. In addition, the multiple openings of the opening groove 311 facilitate the assembly of the cover plate 320 and the elastic connector 200.

[0072] Optionally, the opening groove 311 has a first stepped surface 3111 and a second stepped surface 3112. The first stepped surface 3111 is adjacent to the cover plate body, and the second stepped surface 3112 is away from the cover plate body. The protrusion 321 is located on the second stepped surface 3112, and the second connecting segment 230 is at least partially located between the second stepped surface 3112 and the protrusion 321, so that the protrusion 321 and the second stepped surface 3112 lock the second connecting segment 230. Exemplarily, when the second connecting segment 230 is located on the second stepped surface 3112, the second connecting segment 230 can extend to the first stepped surface 3111. The second connecting segment 230 forms a bend in the opening groove 311. The cover plate body, the first stepped surface 3111, and the protrusion 321 and the second stepped surface 3112 jointly lock the second connecting segment 230, which is beneficial for the second connecting segment 230 to be more securely installed in the first ear clamp arm 300.

[0073] Preferably, the clamping part 310 is provided with a mounting groove 312 on the side near the cover plate 320. The mounting groove 312 is located at the end of the clamping part 310 away from the opening groove 311. The cover plate body is provided with a snap-fit ​​part 322 that cooperates with the mounting groove 312. By snap-fitting the snap-fit ​​part 322 with the mounting groove 312, the connection strength between the cover plate 320 and the clamping part 310 is further improved.

[0074] In actual production applications, the second connecting section 230 and the clamping part 310 can also be fixed by adhesive bonding, or a through hole can be provided on the second connecting section 230 and a fixed shaft that cooperates with the through hole can be provided on the clamping part 310. The connection between the second connecting section 230 and the clamping part 310 is achieved by the cooperation between the through hole and the fixed shaft. These are not described in detail here, but are all within the protection scope of this utility model.

[0075] Furthermore, a first accommodating space 110a is provided within the main body segment 110, and a sound-emitting unit 111 is provided within the first accommodating space 110a for emitting sound. Correspondingly, a second accommodating space 120a is provided within the second ear clip arm 120, and a circuit board 123 and a control unit 124 are provided within the second accommodating space 120a. The control unit 124 is electrically connected to the circuit board 123 and the sound-emitting unit 111, and the circuit board 123 is electrically connected to the sound-emitting unit 111.

[0076] Optionally, a battery (not shown) is also provided in the first accommodating cavity. The battery is located on the side opposite to the sound-emitting unit 111, and is electrically connected to the sound-emitting unit 111, the circuit board 123, and the control unit 124. In other words, the ear-hook headphones of this application can be used in a mobile manner and do not need to be constantly connected to a power source.

[0077] In one embodiment, see Figure 5 This embodiment further describes the second ear clip arm 120, which includes a first rod segment 121 and a second rod segment 122. The first rod segment 121 is disposed at one end of the second rod segment 122, and a first preset angle is provided between the first rod segment 121 and the second rod segment 122. A main body segment 110 is disposed at the end of the first rod segment 121 away from the second rod segment 122, and a first connecting segment 210 is adapted to connect with the second rod segment 122. Accordingly, the first preset angle is provided between the main body segment 110 and the first rod segment 121 for ease of wearing by the user.

[0078] Optionally, the first rod segment 121 and the main body segment 110 are provided with a second preset angle, and the main body segment 110 extends along the direction of the included angle space 100a of the first preset angle. That is, the second rod segment 122 and the first rod segment 121 are bent and connected to form an included angle space 100a, which has the first preset angle. Then the first rod segment 121 is bent again at the main body segment 110, and the main body segment 110 extends toward the included angle space 100a. Finally, the main body segment 110, the first rod segment 121, and the second rod segment 122 form a semi-enclosed wearing space, so that the ear-hook headphones can be better worn on the user's ears. The extension direction of the main body segment 110 in the included angle space 100a of the first preset angle can be toward the second rod segment 122, or it can extend away from the second rod segment 122, or the main body segment 110 can extend parallel to the second rod segment 122.

[0079] Optionally, the first preset angle and the second preset angle can be complementary angles, so that the main body segment 110 extends along the extension direction of the second rod segment 122. It is understood that when the first preset angle and the second preset angle are complementary angles, the sum of the first preset angle and the second preset angle is 180°. In one example, if the main body segment 110 is tilted towards the second rod segment 122, the sum of the first preset angle and the second preset angle is less than 180°, and the wearing space formed by the main body segment 110, the first rod segment 121, and the second rod segment 122 is smaller, which may affect the wearing comfort of the ear-hook headphones. In another example, if the main body segment 110 is tilted away from the second rod segment 122, the sum of the first preset angle and the second preset angle is greater than 180°, and the wearing space formed by the main body segment 110, the first rod segment 121, and the second rod segment 122 is larger, which may lead to instability in the ear-hook headphones. Therefore, setting the sum of the first preset angle and the second preset angle to 180° is beneficial for adapting to the ear shape of most users. Combined with the auxiliary clamping of the first ear clip arm 300, it is convenient for users to wear.

[0080] Understandably, please refer to the accompanying drawings in the instruction manual. Figure 6 When the first ear clip arm 300 is only fitted onto the outside of the second connecting section 230, the transition section 220 is in a bent state and in direct contact with the external environment when the user wears the earphone. Preferably, this ear-hook earphone, which facilitates adjustment of the opening angle, also includes a flexible tube 400. One end of the flexible tube 400 is fitted onto the end of the second ear clip arm 120 near the first ear clip arm 300, and the other end of the flexible tube 400 is fitted onto the end of the first ear clip arm 300 near the second ear clip arm 120. The transition section 220 is located inside the flexible tube 400. It is understood that the flexible tube 400 can isolate the transition section 220 from adverse effects of the external environment, ensuring the structural strength of the transition section 220 and extending its service life. Of course, in addition to the flexible tube 400, an anti-corrosion material can also be applied to the outside of the transition section 220.

[0081] Optionally, the anti-corrosion material may be, but is not limited to, epoxy resin, paint, etc., and this application does not make specific limitations.

[0082] In one embodiment, a recessed groove 330 is provided on one side of the first ear clip arm 300. The recessed groove 330 is located on the same side as the main body segment 110, and the bottom of the recessed groove 330 is arc-shaped. Correspondingly, when the first ear clip arm 300 includes a clamping part 310 and a cover plate 320, the recessed groove 330 is located on the side of the clamping part 310 away from the cover plate 320. In use, when the user wears the ear-hook earphone on their ear, the recessed groove 330 is adapted to contact the auricle to reduce the pressure of the first ear clip arm 300 on the ear and improve wearing comfort.

[0083] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
