Description

[0001] This application claims priority to Chinese Patent Application No. 202323122369.3, filed on November 20, 2023, with the Chinese Patent Office, entitled "An Adjustable Opening Angle Ear Clip Headphone", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of headphone technology, and more particularly to an adjustable-angle clip-on headphone. Background Technology

[0003] With the increasingly fast pace of life, headphones have rapidly gained popularity in recent years. Headphones are small sound output devices that allow users to listen to audio information without disturbing others. With continuous technological advancements, the market has introduced various types of headphones, among which clip-on headphones are an important category.

[0004] Clip-on headphones are a type of headphone with an auxiliary ear clip attached to the side of the main body, and are popular due to their portability. When using clip-on headphones, the opening angle between the main body and the ear clip needs to be adjusted, and this angle is fixed to ensure the headphones stay securely on the user's ears and don't easily fall off. However, current technology makes the structure for fixing the opening angle of clip-on headphones and the ear clip complex, difficult to assemble, and prone to malfunction, resulting in a reduced user experience.

[0005] Therefore, this application aims to provide an ear clip-on headphone with an adjustable opening angle to solve the above problems. Utility Model Content

[0006] The purpose of this application is to provide an ear clip-on earphone with an adjustable opening angle. It uses several pressing surfaces to contact and press with the second ear clip arm or the first ear clip arm to fix the opening angle between the first ear clip arm and the second ear clip arm, thereby achieving multi-angle adjustment, improving the consumer's wearing experience, and has a simple structure and long service life.

[0007] The technical solution provided in this application is as follows:

[0008] An adjustable-angle clip-on earphone includes an earphone body and a first clip arm, wherein the earphone body includes a main body segment and a second clip arm;

[0009] The main body segment is disposed at one end of the second ear clip arm, and the first ear clip arm is rotatably disposed at the end of the second ear clip arm away from the main body segment;

[0015] In one embodiment, a rotating shaft is provided on one side of the two protrusions that are close to each other, and a receiving hole is provided on the extension to mate with the rotating shaft. The two rotating shafts are inserted into the receiving hole so that the first ear clip arm and the second ear clip arm are rotatably connected; or

[0016] Each of the two protrusions is provided with a receiving hole, and the extension is provided with a rotating shaft that cooperates with the receiving hole. The rotating shaft is inserted into the receiving hole so that the first ear clip arm and the second ear clip arm are rotatably connected.

[0017] In one embodiment, when the rotating shaft is disposed on the protrusion, two corresponding side edges on one side of the extension are respectively provided with clearance grooves, the two clearance grooves are disposed opposite to each other, and the clearance grooves are adapted to cooperate with the rotating shaft.

[0018] In one embodiment, the clearance groove and the sidewall adjacent to the extension are connected by an arc surface.

[0019] In one embodiment, the first ear clip arm has a natural state and an ear-clamping state. In the natural state, the first ear clip arm is extended relative to the second ear clip arm, and the extension direction of the first ear clip arm is along the extension direction of the main body segment. In the ear-clamping state, the first ear clip arm forms an angle with the second ear clip arm, and the extension direction of the main body segment is toward the first ear clip arm.

[0020] In one embodiment, the extrusion surfaces are provided at least three, and the included angle between any two adjacent extrusion surfaces is equal.

[0021] In one embodiment, a first accommodating space is provided within the main body segment, and a sound-emitting unit is provided within the first accommodating space, the sound-emitting unit being used to emit sound;

[0023] In one embodiment, a sound outlet is provided on the main body segment, and the sound outlet is positioned directly opposite the sound-producing unit; and / or

[0024] A battery is also provided in the first accommodating space, and the battery is located on the side opposite to the sound-emitting unit and facing the sound outlet.

[0025] In one embodiment, the first ear clip arm and the protrusion are made of soft rubber.

[0026] In one embodiment, the second ear clip arm includes a first part and a second part. One end of the first part is connected to the main body segment at a first preset angle. The end of the first part away from the main body segment is adapted to be connected to the second part at a second preset angle. The end of the second part away from the first part is adapted to be connected to the first ear clip arm. The main body segment extends along the direction of the included angle space of the first preset angle.

[0027] In one embodiment, the first preset angle and the second preset angle are complementary angles, and the main body segment extends along the extension direction of the second part.

[0028] In one embodiment, a groove is provided on one side of the first ear clip arm, the groove being configured to adapt to the arcuate surface behind the user's auricle.

[0029] In one embodiment, the bottom of the inner groove is provided with friction texture.

[0030] The adjustable-angle clip-on earphone provided in this application has the following beneficial effects:

[0031] 1. This application provides an adjustable opening and closing angle ear clip earphone, in which a first ear clip arm and a second ear clip arm are rotatably connected together. During use, the user can choose to press the second ear clip arm or the first ear clip arm against different pressing surfaces according to their own ear shape, thereby fixing the opening and closing angle between the first ear clip arm and the second ear clip arm. This makes the ear clip earphone less likely to fall off, improving the user's wearing experience. Moreover, the opening and closing angle can be fixed without the need for other devices between the first ear clip arm and the second ear clip arm, making the structure simple, easy to maintain, and reducing costs.

[0046] 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.

[0047] In one embodiment, an adjustable-angle ear clip earphone is described, which has a protrusion 300 on a first ear clip arm 200 or a second ear clip arm 120. When the first ear clip arm 200 and the second ear clip arm 120 rotate relative to each other, the pressing surface 320 on the protrusion 300 can contact and press with the first ear clip arm 200 or the second ear clip arm 120, thereby fixing the opening angle between the first ear clip arm 200 and the second ear clip arm 120.

[0048] Specifically, please refer to the accompanying drawings in the instruction manual. Figures 1 to 3 An adjustable-angle clip-on earphone includes an earphone body 100, a protrusion 300, and a first ear clip arm 200. Accordingly, the earphone 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 and is adapted to be worn inside the user's ear. The first ear clip arm 200 is disposed at the end of the second ear clip arm 120 away from the main body segment 110, and the first ear clip arm 200 and the second ear clip arm 120 are capable of relative rotation.

[0049] A protrusion 300 is provided on the side wall along the longitudinal direction of one of the first ear clip arms 200 or the second ear clip arm 120. Correspondingly, a plurality of sequentially connected extrusion surfaces 320 are provided on one side of the protrusion 300. The plurality of extrusion surfaces 320 are sequentially connected, and an included angle α is formed between each two adjacent extrusion surfaces 320, such that the radial cross section of the protrusion 300 is a semi-polygon, that is, the protrusion 300 is a prism that splits from the axis of symmetry of the top surface along the vertical direction to the bottom surface.

[0050] It is understandable that when the protrusion 300 is provided on the first ear clip arm 200 or the second ear clip arm 120, one side of the protrusion 300 is connected to the first ear clip arm 200 or the second ear clip arm 120, and only the other side of the protrusion 300 can be provided with the extrusion surface 320. Therefore, when multiple extrusion surfaces 320 are provided on the other side of the protrusion 300, the shape of the protrusion 300 partially has polygonal characteristics, that is, the overall shape of the protrusion 300 is like... Figure 1 The example resembles a polygon cut in half.

[0051] Understandably, when the protrusion 300 is disposed on the first ear clip arm 200, and the first ear clip arm 200 and the second ear clip arm 120 rotate relative to each other, the pressing surface 320 is adapted to press against the second ear clip arm 120. When rotated to a suitable angle, the pressing surface 320 and the second ear clip arm 120 make it difficult for the first ear clip arm 200 and the second ear clip arm 120 to rotate, thereby maintaining the opening and closing angle. Correspondingly, when the protrusion 300 is disposed on the second ear clip arm 120, and the first ear clip arm 200 and the second ear clip arm 120 rotate relative to each other, the pressing surface 320 is adapted to press against the first ear clip arm 200, making it difficult for the first ear clip arm 200 and the second ear clip arm 120 to rotate, thereby maintaining the opening and closing angle.

[0052] In this embodiment, the first ear clip arm 200 and the second ear clip arm 120 can rotate relative to each other, thereby adjusting the opening angle. This allows the ear clip-on headphones to be suitable for different ear shapes and can be used in scenarios such as work, study, and sports. They are comfortable to wear and do not easily fall off. In use, the user can rotate the first ear clip arm 200 and the second ear clip arm 120 to adjust the opening angle according to their own ear shape, achieving a suitable opening angle. Then, the headphone body 100 is worn in front of the ear, and the first ear clip arm 200 is worn behind the ear.

[0053] It is worth noting that the opening and closing angle between the first ear clip arm 200 and the second ear clip arm 120 can be fixed through the protrusion 300. The structure is simple and easy to assemble and maintain.

[0054] In some embodiments, when the protrusion 300 is disposed on the first ear clip arm 200, the protrusion 300 rotates to engage with the end of the second ear clip arm 120 away from the main body segment 110, thereby switching between different compression surfaces 320 contacting and compressing the end of the second ear clip arm 120 away from the main body segment 110. For example, when the protrusion 300 rotates relative to the second ear clip arm 120, the compression surfaces 320 can be switched to contact the second ear clip arm 120 one by one. When different compression surfaces 320 contact the second ear clip arm 120, the angle between the first ear clip arm 200 and the second ear clip arm 120 will also be different. This allows the ear clip headphones to present different opening and closing angles to clamp the ears of different users, improving the adaptability of the ear clip headphones to different user groups.

[0055] Optionally, the first ear clip arm 200 has a natural state and an ear clipping state. In the natural state, the first ear clip arm 200 is unfolded relative to the second ear clip arm 120, and the extension direction of the first ear clip arm 200 is along the extension direction of the main body segment 110. In the ear clipping state, the first ear clip arm 200 and the second ear clip arm 120 form an angle α, and the extension direction of the main body segment 110 is towards the first ear clip arm 200.

[0056] For example, when the protrusion 300 rotates relative to the second ear clip arm 120, and the first ear clip arm 200 rotates relative to the second ear clip arm 120 to a parallel unfolded position (i.e., the angle between the first ear clip arm 200 and the second ear clip arm 120 is 180°), the ear clip earphone is in a natural state, facilitating its storage. When the first ear clip arm 200 rotates relative to the second ear clip arm 120 to an angle α (i.e., the angle between the first ear clip arm 200 and the second ear clip arm 120 can be 1°-179°), the ear clip earphone is in a clipped-on state.

[0057] It is understandable that the more extrusion surfaces 320 are set, the more adjustable the angle between the first ear clamp arm 200 and the second ear clamp arm 120 becomes, which is beneficial for achieving multi-level adjustment.

[0058] In one embodiment, see the accompanying drawings. Figure 2 This embodiment further describes the first ear clip arm 200. For ease of explanation, taking the example of a protrusion 300 located on the side wall of the first ear clip arm 200 along its length, the protrusion 300 is located near the second ear clip arm 120 (the protrusion 300 is located at one end of the first ear clip arm 200 near the second ear clip arm 120). There are two protrusions 300, which are correspondingly located at both ends of the first ear clip arm 200 along its width, and are spaced apart to allow for rotatable engagement with the end of the second ear clip arm 120 near the first ear clip arm 200.

[0059] Furthermore, the second ear clip arm 120 is provided with an extension 121 at the end away from the main body section 110. The extension 121 is disposed between the two protrusions 300 and is adapted to rotate and cooperate with the protrusions 300.

[0060] Furthermore, a rotating shaft 310 is provided on the protrusion 300. The rotating shaft 310 is located on the side where the two protrusions 300 are close to each other. The extension 121 is provided with a receiving hole 122 that cooperates with the rotating shaft 310. The two rotating shafts 310 are inserted into the receiving hole 122, so that the first ear clip arm 200 rotates relative to the second ear clip arm 120 through the rotating shaft 310.

[0061] Of course, the rotating shaft 310 can also be provided on the extension 121, and the receiving hole 122 can be provided on the two protrusions 300. The rotating shaft 310 is inserted into the receiving hole 122 on the protrusion 300, so that the first ear clip arm 200 rotates relative to the second ear clip arm 120 through the rotating shaft 310.

[0062] When using, please refer to the attached diagram in the instruction manual. Figures 1 to 3 When the earphones are not being worn, the user rotates the first ear clip 200 relative to the second ear clip 120, causing the opening angle between the first ear clip 200 and the second ear clip 120 to gradually decrease from 180°. Rotation continues until a pressing surface 320 contacts the end of the second ear clip 120 closest to the first ear clip 200, thus fixing the opening angle. Alternatively, the user can continue rotating the first ear clip 200 to separate the previously pressed surface 320 from the second ear clip 120. When the appropriate pressing surface 320 contacts the second ear clip 120, rotation stops, maintaining the fixed opening angle, allowing the ear clip earphones to be worn on the ears.

[0063] It is understood that the protrusion 300 can be provided not only on the first ear clip arm 200, but also on the second ear clip arm 120, and positioned close to the first ear clip arm 200. Accordingly, there are two protrusions 300, correspondingly positioned at opposite ends of the second ear clip arm 120 in the width direction. An extension 121 is positioned at one end of the first ear clip arm 200 close to the second ear clip arm 120, and located between the two protrusions 300. A rotating shaft 310 is provided on each of the two protrusions 300, and a receiving hole 122 is provided on the extension 121 to mate with the rotating shaft. Of course, the rotating shaft 310 can be positioned on the extension 121, and the receiving hole 122 on the protrusion 300; this will not be described in detail here. Both arrangements, to achieve rotational engagement between the first ear clip arm 200 and the second ear clip arm 120, are within the scope of protection of this application.

[0064] Optionally, when the protrusion 300 is provided on the first ear clip arm 200 or the second ear clip arm 120, the protrusion 300 can be integrally formed with the first ear clip arm 200 or the second ear clip arm 120. That is, the protrusion 300 is not a separate component that can be detached from the first ear clip arm 200 or the second ear clip arm 120, but is an integrally formed structure during the production process. Taking injection molding as an example, when the first ear clip arm 200 or the second ear clip arm 120 is produced by injection molding, the protrusion 300 is provided on the mold, and then the first ear clip arm 200 or the second ear clip arm 120 and the protrusion 300 are injection molded simultaneously.

[0065] Of course, as in other embodiments, the protrusion 300 may also be separately disposed from the first ear clip arm 200 or the second ear clip arm 120. For example, in the overall assembly process of this ear clip earphone, the protrusion 300 is first installed on the first ear clip arm 200 or the second ear clip arm 120, and finally the first ear clip arm 200 and the second ear clip arm 120 are installed.

[0066] In one embodiment, see the accompanying drawings. Figure 2 This embodiment further describes the protrusion 300. Specifically, at least three extrusion surfaces 320 are provided, and preferably, the included angle between any two adjacent extrusion surfaces 320 is equal. It can be understood that when the first extrusion surface 320 is in extrusion contact with the second ear clamp arm 120, rotating the first ear clamp arm 200 causes the first extrusion surface 320 to separate from the second ear clamp arm 120. Continuing to rotate causes the second extrusion surface 320 to come into contact with the second ear clamp arm 120, and so on. Each rotation of an extrusion surface 320 results in the same degree of change in the opening and closing angle.

[0067] Understandably, the more extrusion surfaces 320 there are, the smaller the range of change in opening and closing angle with each rotation of an extrusion surface 320, resulting in more precise adjustment of the opening and closing angle of the clip-on earphones. This allows users to accurately adjust to a suitable opening and closing angle, improving wearing comfort and enhancing the user experience.

[0068] In actual production applications, manufacturers can select the number of extrusion surfaces 320 on the protrusion 300 according to the actual situation in order to adjust the opening and closing angle. These will not be described in detail here, but are all within the scope of protection of this application.

[0069] In one embodiment, see the accompanying drawings. Figure 4 and Figure 5 The first ear clip arm 200 and the protrusion 300 are both made of soft rubber, which has good softness and elasticity.

[0070] Furthermore, a protrusion 300 is provided on the first ear clip arm 200, and a rotating shaft 310 is provided on the side where the two protrusions 300 are close to each other. A clearance groove 123 is provided on two opposing sides of one sidewall of the extension 121. Accordingly, the clearance groove 123 is provided on the side so that the groove edge of the clearance groove 123 is connected to the external environment. The two clearance grooves 123 are oppositely arranged and adapted to cooperate with the rotating shaft 310.

[0071] Understandably, the two clearance slots 123 are provided on the extension 121. In actual production applications, when it is necessary to install the first ear clamp arm 200 on the second ear clamp arm 120, the rotating shaft 310 on the two protrusions 300 can be placed in the clearance slots 123 first. Due to the good flexibility and elasticity of the protrusions 300, the operator can increase the distance between the two protrusions 300, and then insert the rotating shaft 310 into the receiving hole 122. This facilitates operation, shortens assembly time, and improves production efficiency.

[0072] Preferably, the adjacent sidewalls of the clearance groove 123 and the extension 121 are connected by a smooth arc surface so that the rotating shaft 310 can be transferred from the clearance groove 123 to the receiving hole 122.

[0073] In one embodiment, see the accompanying drawings. Figure 6 This embodiment further describes the headphone body 100. Specifically, a first accommodating space 110a is provided within the main body segment 110, and a second accommodating space 120a is provided within the second ear clip arm 120. Correspondingly, a sound-emitting unit 111 is provided within the first accommodating space 110a, and the main body segment 110 emits sound through the sound-emitting unit 111. A circuit board 124 is provided within the second accommodating space 120a, and the circuit board 124 is electrically connected to the sound-emitting unit 111 to control the opening and closing of the sound-emitting unit 111.

[0074] Furthermore, the main body section 110 is also provided with a sound outlet (not shown), which is positioned directly opposite the sound-emitting unit 111. In use, the sound emitted by the sound-emitting unit 111 is transmitted to the user's ear through the sound outlet.

[0075] Optionally, a battery (not shown) is also provided in the first accommodating cavity 110a. The battery is located on the side opposite to the sound-emitting unit 111 facing the sound outlet, and the battery is electrically connected to the sound-emitting unit 111 and the circuit board 124. In other words, the ear clip-on headphones of this application can be used in a portable manner and do not need to be constantly connected to a power source.

[0076] In one embodiment, see the accompanying drawings. Figure 6 The second ear clip arm 120 includes a first portion 125 and a second portion 126. A main body segment 110 is disposed at one end of the first portion 125, and the first portion 125 and the main body segment 110 are connected at a first preset angle β. The second portion 126 is disposed at the end of the first portion 125 away from the main body segment 110, and the first portion 125 and the second portion 126 are connected at a second preset angle γ. Correspondingly, the end of the second portion 126 away from the first portion 125 is rotatably connected to the first ear clip arm 200, and an extension portion 121 is provided at the end of the second portion 126 away from the first portion 125. The main body segment 110 extends along the direction of the included angle space of the first preset angle β. That is, the second portion 126 and the first portion 125 are bent and connected to form an included angle space 100a, which has the first preset angle β. Then, the first part 125 bends 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 part 125, and the second part 126 form a semi-enclosed wearing space, so that the ear clip-on 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 at the first preset angle β can be toward the second part 126, or away from the second part 125, or the main body segment 110 can be parallel to the second part.

[0077] Optionally, the first preset angle β and the second preset angle γ can be complementary angles, so that the main body segment 110 extends along the extension direction of the second part 126. It is understood that when the first preset angle β and the second preset angle γ are complementary angles, the sum of the first preset angle β and the second preset angle γ is 180°. In one example, if the main body segment 110 is tilted towards the second part 126, the sum of the first preset angle β and the second preset angle γ is less than 180°, and the wearing space formed by the main body segment 110, the first part 125, and the second part 126 is smaller, which may affect the wearing comfort of the ear-clip headphones. In another example, if the main body segment 110 is tilted away from the second part 126, the sum of the first preset angle β and the second preset angle is greater than 180°, and the wearing space formed by the main body segment 110, the first part 125, and the second part 126 is larger, which may cause the ear-clip headphones to be unstable when worn. Therefore, setting the sum of the first preset angle β and the second preset angle γ to 180° is beneficial for adapting to the ear shape of most users. Combined with the auxiliary clamping of the first ear clip arm 200, it is convenient for users to wear.

[0078] Understandably, the setting of the first preset angle β and the second preset angle γ can better fit the earphone body 100 to the user's ear, making it easier to wear the earphone body 100 on the ear.

[0079] In one embodiment, see the appendix to the specification. Figure 5 The first ear clip arm 200 is provided with an inner groove 210, and the bottom of the groove 210 is a concave arc surface. This allows the first ear clip arm 200 to better adapt to the arc surface behind the user's auricle, thereby reducing the pressure of the first ear clip arm 200 on the ear and improving wearing comfort.

[0080] Preferably, the bottom of the groove 210 is provided with friction texture to increase the friction between the first ear clip arm 200 and the ear, thereby reducing the possibility of the ear clip earphone falling off.

[0081] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. 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 application, and these improvements and modifications should also be considered within the protection scope of this application.
