Abstract
Description
Technical Field
[0001] This application relates to the field of sound-generating components technology, and more particularly to a sound-generating component and an ear clip-on headphone. Background Technology
[0002] Headphones are widely used in people's daily lives, and they can be used with electronic devices such as mobile phones and computers to provide users with sound playback functions. Among them, clip-on headphones are a new type of headphone. They are usually small in size and do not need to be inserted into the ear canal. They are simply fixed to the ear with an ear clip, avoiding pressure on the ear canal and making them suitable for long-term wear.
[0003] The related technology of ear clip-on headphones includes a mounting frame and two sound modules. The two sound modules are assembled at both ends of the mounting frame to improve the sound quality of the ear clip-on headphones. However, when the ear clip-on headphones of this technology are subjected to external force, the sound modules are easy to separate from the mounting frame, which will lead to a poor user experience. Utility Model Content
[0004] This application discloses a sound-generating component and an ear clip-on earphone, which can reduce the risk of the sound-generating module separating from the mounting bracket when the ear clip-on earphone is subjected to external force.
[0005] To achieve the above objectives, in a first aspect, embodiments of this application disclose a sound-generating component, including:
[0006] The mounting frame is cylindrical and has a sound-guiding hole extending from its inner circumferential surface to its outer circumferential surface.
[0007] Two sound-generating modules, each sound-generating module comprising a frame and a sound-generating unit, the sound-generating unit being disposed within a corresponding frame, and the two frames being respectively connected to both sides of the mounting frame along the axial direction of the mounting frame;
[0008] The two basin frames each have a tailbone formed around the outer peripheral surface of the mounting frame, and the tailbone is radially positioned and engaged with the mounting frame.
[0009] In an alternative embodiment, the coccyx is made of a metallic material.
[0010] In one optional embodiment, the outer diameter of the coccyx is the maximum outer diameter of the sound-generating component, the thickness of the coccyx along the radial direction of the mounting bracket is t, and the inner diameter of the coccyx is n, wherein (t / n) < 0.04.
[0011] In one alternative embodiment, 10mm ≤ n ≤ 13mm.
[0012] In one optional embodiment, the outer diameter of the coccyx is d, and the outer diameter of the coccyx is the maximum outer diameter of the sound-generating component;
[0013] The maximum axial dimension of the sound-generating component is h, where 0.6 ≤ (h / d) ≤ 0.8.
[0014] In one alternative embodiment, 6mm ≤ h ≤ 10.4mm.
[0015] In one optional embodiment, the sound-generating unit includes a diaphragm disposed within a corresponding frame, and the two diaphragms are respectively fitted to both ends of the mounting frame along its own axial direction. Along the axial direction of the mounting frame, the minimum distance between the two diaphragms is 1.5mm to 2.0mm.
[0016] In one alternative embodiment, the outer peripheral surfaces of both ends of the mounting bracket are respectively bonded to the inner peripheral surfaces of the corresponding coccyx.
[0017] In one optional embodiment, the outer peripheral surfaces at both ends of the mounting bracket are provided with glue storage grooves, the glue storage grooves extend circumferentially along the mounting bracket, and the openings of the glue storage grooves face the coccyx.
[0018] In one optional embodiment, the mounting frame includes a cylindrical body and two limiting portions. The cylindrical body has two end faces distributed along its own axial direction. The two limiting portions are respectively disposed on the two end faces of the cylindrical body. The two basin frames respectively form two tail ribs around the outer peripheral surface of the limiting portions. The tail ribs are radially limited and engaged with the limiting portions of the mounting frame.
[0019] The outer peripheral surface of the limiting part is bonded to the inner peripheral surface of the coccyx, and the outer diameter of the cylinder is smaller than the outer diameter of the coccyx.
[0020] In one optional embodiment, the sound-generating unit includes a diaphragm disposed within a corresponding frame, and the two diaphragms respectively engage with both ends of the mounting frame along their own axial direction.
[0021] Along the axial direction of the mounting bracket, both ends of the mounting bracket are in contact with the outer peripheral portions of the two diaphragms, respectively.
[0022] In one optional embodiment, an anti-rotation structure is provided between the mounting frame and the two basin stands, the anti-rotation structure being used to restrict the relative movement of the mounting frame and the basin stands along the circumference of the mounting frame.
[0023] In one optional embodiment, the sound-generating unit includes a diaphragm disposed in a corresponding frame, and the two diaphragms are respectively engaged with both ends of the mounting frame along their own axial direction. The frame and the diaphragms cooperate to form a pressure relief cavity, which is located on the side of the diaphragm away from the first cavity.
[0024] The anti-rotation structure includes an anti-rotation protrusion and an anti-rotation groove. The anti-rotation groove is disposed on the basin frame, penetrates the basin frame, and is connected to the pressure relief chamber.

[0028] The sound-generating component of this application includes a mounting bracket and two sound-generating modules. The two sound-generating modules are respectively connected to both sides of the mounting bracket along the axial direction of the mounting bracket. Since the sound pressure level is an important parameter for measuring the performance of the sound-generating component, and the sound pressure level of the sound-generating component is proportional to the number of sound-generating modules, compared with setting only one sound-generating module, this application can effectively improve the sound pressure level of the sound-generating component and achieve a better volume effect by using two sound-generating modules in conjunction with the mounting bracket to form a first cavity.
[0029] The sound-generating module of this application includes a frame and a sound-generating unit. The sound-generating unit is located inside the frame. The two frames are respectively connected to both ends of the mounting frame. The two frames are respectively formed with tail ribs around the outer peripheral surface of the mounting frame. The tail ribs are radially limited and engaged with the mounting frame. This can limit the relative movement of the frame and the mounting frame in the radial direction of the mounting frame, improve the stability of the fit between the frame and the mounting frame, and reduce the risk of the sound-generating module separating from the mounting frame when the ear clip headphones are subjected to external force.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0049] This application discloses a sound-generating component and an ear-clip earphone, which solves the problems of large size and poor user experience associated with related ear-clip earphones and other electronic devices. The sound-generating component and ear-clip earphone provided in this application will be described in detail below with reference to the accompanying drawings and specific embodiments and application scenarios.
[0050] like Figures 4 to 7As shown in the illustration, this application discloses a sound-generating component. This sound-generating component can be applied to headphones, smartphones, tablets, smartwatches, music players, etc. This application does not limit the application environment of this sound-generating component. The sound-generating component includes:
[0051] The mounting bracket 100 is cylindrical and has a sound-guiding hole that extends from its inner circumferential surface to its outer circumferential surface, thereby connecting the internal space of the mounting bracket 100 with the external environment.
[0052] Two sound-generating modules 200 are provided, each including a frame 210 and a sound-generating unit. The sound-generating unit is disposed within a corresponding frame 210. The two frames 210 are respectively connected to both sides of the mounting frame 100 along its axial direction. Specifically, the mounting frame 100 and the two sound-generating units can cooperate to form a first cavity 201. The first cavity 201 is connected to a sound inlet and serves as the location for the sound-generating unit to vibrate and push air to generate sound waves for the user to listen to.
[0053] Two basin frames 210 are respectively formed with tail bones 211 around the outer peripheral surface of the mounting frame 100, and the tail bones 211 are radially limited to the mounting frame 100.
[0054] The sound-generating component of this application includes a mounting bracket 100 and two sound-generating modules 200. The two sound-generating modules 200 are respectively connected to both sides of the mounting bracket 100 along the axial direction of the mounting bracket 100. Since the sound pressure level is an important parameter for measuring the performance of the sound-generating component, and the sound pressure level of the sound-generating component is proportional to the number of sound-generating modules 200, compared with setting only one sound-generating module 200, this application uses two sound-generating modules 200 to cooperate with the mounting bracket 100 to form a first cavity 201 to emit sound, which can effectively improve the sound pressure level of the sound-generating component and achieve a better volume effect.
[0055] The sound-generating module 200 of this application includes a frame 210 and a sound-generating unit. The sound-generating unit is disposed inside the frame 210. The two frames 210 are respectively connected to the two ends of the mounting frame 100. The two frames 210 respectively form a tailbone 211 around the outer peripheral surface of the mounting frame 100. The tailbone 211 and the mounting frame 100 are radially limited and matched. This can limit the relative movement of the frame 210 and the mounting frame 100 in the radial direction of the mounting frame 100, improve the matching stability of the frame 210 and the mounting frame 100, and reduce the risk of the sound-generating module 200 separating from the mounting frame 100 when the ear clip headphones are subjected to external force.
[0056] In one alternative embodiment, the coccyx 211 is made of metal. Exemplarily, the outer diameter of the coccyx 211 can be the maximum outer diameter of the sound-generating component. It should be noted that the entire basin frame 210 can be made of metal, or only the coccyx 211 of the basin frame 210 can be made of metal, while the rest of the basin frame 210, excluding the coccyx 211, is made of plastic.
[0057] The coccyx 211 of this application is made of metal. Compared with plastic, metal has higher density and structural strength. Therefore, even if the coccyx 211 of this application is relatively thin, it can still meet the stability requirements of radial limiting of the mounting frame 100. Obviously, this can reduce the radial dimension of the frame 210, reduce the size of electronic devices using the sound-generating components of this application, such as ear clip headphones, and improve the user experience.
[0058] In one alternative embodiment, please refer to Figure 6 and Figure 7 The outer diameter of the coccyx 211 is the maximum outer diameter of the sound-generating component. The thickness of the coccyx 211 along the radial direction of the mounting bracket 100 is t, and the inner diameter of the coccyx 211 is n, where (t / n) < 0.04. For example, (t / n) can be 0.01, 0.012, 0.015, 0.017, 0.02, 0.023, 0.025, 0.026, 0.028, 0.029, 0.030, 0.031, 0.035, 0.038, etc. This application does not limit the specific value of (t / n). For example, 0.1mm ≤ t < 0.4mm, and t can specifically be 0.13mm, 0.16mm, 0.2mm, 0.25mm, 0.3mm, 0.38mm, etc. This application does not limit the specific value of t. Furthermore, (t / n) < 0.03 and (t / n) ≥ 0.01.
[0059] When designing the frame 210, the size of the space inside the frame 210 is selected based on the external dimensions of the sound-generating units installed inside, such as the diaphragm 221, voice coil, and magnetic circuit system. At this point, the internal dimensions of the frame 210 are determined, that is, the inner diameter of the coccyx 211 is determined. In other words, n is determined before t is determined. The outer diameter d of the coccyx 211 is d = n + 2t. Therefore, the larger the value of (t / n), the larger t and d are, that is, the larger the maximum outer diameter of the sound-generating components; the smaller the value of (t / n), the smaller t and d are, that is, the smaller the maximum outer diameter of the sound-generating components.
[0060] As the above analysis shows, with a fixed inner diameter of the coccyx 211, if (t / n) ≥ 0.04, the values of t and d will increase, thereby weakening the effect of thinning the coccyx 211 in this application. This results in a smaller reduction in the size of electronic devices using the sound-generating component of this application, such as clip-on headphones. Therefore, this application ensures that (t / n) < 0.04, thereby reducing the values of t and d, thus enhancing the effect of thinning the coccyx 211. This leads to a greater reduction in the size of electronic devices using the sound-generating component of this application, such as clip-on headphones, and is more conducive to the miniaturization of such electronic devices.
[0061] In one optional embodiment, 10mm ≤ n ≤ 13mm, that is, the outer diameter of the coccyx 211 is 10~13mm. For example, n can be 10.4mm, 10.9mm, 11mm, 11.3mm, 11.6mm, 12mm, 12.2mm, 12.5mm, 12.8mm, etc., and this application does not limit the specific value of n.
[0062] If n is less than 10mm, the inner diameter of the coccyx 211 is too small, the radial dimension of the internal space of the frame 210 is too small, the volume of the internal space of the frame 210 is too small, and the volume used to install the sound unit is too small. This will compress the external dimensions and volume of the sound unit. Since the external dimensions and volume of the sound unit are proportional to the sound pressure level of the sound-generating component, if the external dimensions and volume of the sound unit are compressed too much, the sound pressure level of the sound-generating component will be reduced too much, resulting in poor volume performance. If n is greater than 13mm, the inner and outer diameters of the coccyx 211 are too large. An excessively large outer diameter of the coccyx 211 will result in an excessively large radial dimension of the frame 210, which will reduce the size of electronic devices using the sound-generating component of this application, such as clip-on headphones, to a lesser extent, affecting the user's experience.
[0063] Therefore, in this embodiment, n is controlled within 10~13mm, which allows the inner diameter of the coccyx 211 to be within a suitable range, thereby allowing the volume of the internal space of the frame 210 to be within a suitable range, and the external dimensions and volume of the sound-generating unit to be within a suitable range, ensuring that the sound-generating component has a large sound pressure level and a good volume effect. At the same time, this embodiment also allows the outer diameter of the coccyx 211 to be within a suitable range, thereby allowing the radial dimension of the frame 210 to be within a suitable range, so as to increase the reduction in size of electronic devices such as clip-on headphones and improve the user experience.
[0064] In one alternative embodiment, please refer to Figure 6The outer diameter of the coccyx 211 is d, which is the maximum outer diameter of the sound-generating component. The maximum axial dimension of the sound-generating component is h, meaning that the maximum dimension of the sound-generating component along the axial direction of the mounting bracket 100 is h, where 0.6 ≤ (h / d) ≤ 0.8. For example, (h / d) can be 0.62, 0.65, 0.66, 0.69, 0.71, 0.72, 0.75, 0.76, 0.78, 0.79, etc. This application does not limit the specific value of (h / d).
[0065] When designing the sound-generating assembly, the maximum outer diameter of the frame 210 is usually determined based on the sound-generating unit, which is the outer diameter of the coccyx 211 in this embodiment. Then, the maximum dimension of the sound-generating assembly along the axial direction of the mounting frame 100 is determined based on the axial dimension of the sound-generating module 200 along the axial direction of the mounting frame 100 and the minimum axial distance between the two sound-generating modules 200. In other words, the value of d has been confirmed before h is determined.
[0066] If (h / d) is less than 0.6, then h is too small, which will result in the axial dimension of the sound module 200 being too small or the minimum axial distance between the two sound modules 200 being too small. If the axial dimension of the sound module 200 is too small, then the volume of the sound module 200 will be too small, the sound pressure level of the sound component will be reduced too much, and the volume effect will be poor. If the minimum axial distance between the two sound modules 200 is too small, then the volume of the first cavity 201 formed between the two sound modules 200 will be too small, reducing the sound quality. If (h / d) is greater than 0.8, then h is too large, which will result in the maximum axial dimension of the sound component being too large, thus resulting in the volume of the sound component being too large. This will cause electronic devices using the sound component of this application, such as ear-clip headphones, to be too large, resulting in a poor user experience.
[0067] Therefore, in this embodiment, (h / d) is controlled at 0.6~0.8, so that the maximum axial dimension of the sound-generating component is within a suitable range. This not only ensures that the axial dimension of the sound-generating module 200 and the volume of the first cavity 201 are within a suitable range, thereby guaranteeing the sound quality and volume effect of the sound-generating component, but also ensures that the volume of electronic devices using the sound-generating component of this application, such as ear clip-on headphones, is within a suitable range, thus improving the user experience.
[0068] In one optional embodiment, 6mm ≤ h ≤ 10.4mm. For example, h can be 6.5mm, 7.0mm, 7.6mm, 8.2mm, 8.8mm, 9.2mm, 9.4mm, 8.6mm, 10mm, etc., and this application does not limit the specific value of h.
[0069] If h is less than 6mm, then h is too small, which will result in the axial dimension of the sound-generating module 200 being too small or the minimum axial distance between the two sound-generating modules 200 being too small. If the axial dimension of the sound-generating module 200 is too small, the volume of the sound-generating module 200 will be too small, the sound pressure level of the sound-generating component will be reduced excessively, and the volume effect will be poor. If the minimum axial distance between the two sound-generating modules 200 is too small, the volume of the first cavity 201 formed between the two sound-generating modules 200 will be too small, reducing the sound quality. If h is greater than 10.4mm, then h is too large, which will result in the maximum axial dimension of the sound-generating component being too large, thus resulting in the volume of the sound-generating component being too large. This will lead to electronic devices using the sound-generating component of this application, such as clip-on headphones, being too large, resulting in a poor user experience. In an optional embodiment, please refer to... Figure 6 The sound-generating unit includes a diaphragm 221. Exemplarily, the sound-generating unit may also include a voice coil (not shown) and a magnetic circuit system (not shown). Both the diaphragm 221 and the magnetic circuit system are disposed within the frame 210. The voice coil is connected to the diaphragm 221 and is positioned within the magnetic field formed by the magnetic circuit system. The voice coil may be cylindrical, and its axis may be aligned with the axis of the frame 210. The voice coil moves along its axis under the influence of the magnetic field formed by the magnetic circuit system, thereby causing the diaphragm 221 to vibrate and generate sound waves.
[0070] The diaphragm 221 is disposed within the corresponding frame 210. The two diaphragms 221 respectively mate with both ends of the mounting bracket 100 along its axial direction. That is, the first cavity 201 mentioned above is formed between the two diaphragms 221. Along the axial direction of the mounting bracket 100, the minimum distance between the two diaphragms 221 is 1.5mm to 2.0mm. It should be noted that the minimum distance between the two diaphragms 221 is determined by… Figure 6 The dimension w is shown in the figure. For example, the minimum distance between the two diaphragms 221 can be 1.6mm, 1.7mm, 1.8mm, 1.9mm, etc., and this application does not limit the minimum distance between the two diaphragms 221.
[0071] If the minimum distance between the two diaphragms 221 is less than 1.5mm, the volume of the first cavity 201 formed between the two diaphragms 221 will be too small, which will reduce the sound quality of the sound-generating component. If the minimum distance between the two diaphragms 221 is greater than 2.0mm, it will result in the axial dimension of the sound-generating component being too large, which will lead to the volume of the sound-generating component being too large, resulting in the electronic devices using the sound-generating component of this application, such as ear clip headphones, being too large, affecting the user's user experience.
[0072] Therefore, in this embodiment, the minimum distance between the two diaphragms 221 is controlled at 1.5mm to 2.0mm, which can ensure that the volume of the first cavity 201 formed between the two diaphragms 221 is within a suitable range, so as to ensure the sound quality of the sound-generating component; and, after the minimum distance between the two diaphragms 221 is within a suitable range, the axial dimension and volume of the sound-generating component can be within a suitable range, so as to meet the miniaturization requirements of the sound-generating component and improve the user experience.
[0073] In one alternative embodiment, please refer to Figure 6 and Figure 7 The outer peripheral surfaces of both ends of the mounting bracket 100 are respectively bonded to the inner peripheral surfaces of the corresponding coccyx 211.
[0074] In this embodiment, the outer peripheral surfaces of both ends of the mounting bracket 100 are bonded to the inner peripheral surfaces of the corresponding coccyx 211. Compared to embodiments where the end faces of the coccyx 211 are bonded to the end faces of the mounting bracket 100, the contact area between the outer peripheral surface of the mounting bracket 100 and the inner peripheral surface of the coccyx 211 is larger. Therefore, the bonding area between the outer peripheral surface of the mounting bracket 100 and the inner peripheral surface of the coccyx 211 is larger, resulting in higher bonding strength. This improves the assembly stability of the mounting bracket 100 and the coccyx 211. Of course, the mounting bracket 100 and the coccyx 211 can also be connected by ultrasonic welding or other methods. This application does not limit the connection method between the mounting bracket 100 and the coccyx 211.
[0075] In one alternative embodiment, please refer to Figure 7 The outer peripheral surfaces of both ends of the mounting frame 100 are provided with glue storage grooves 101. The glue storage grooves 101 extend along the circumference of the mounting frame 100, and the opening of the glue storage grooves 101 faces the coccyx 211.
[0076] The specific bonding process is as follows: apply adhesive to the outer peripheral surface of the mounting bracket 100, insert the mounting bracket 100 into the coccyx 211, and let it stand for a preset time to complete the bonding. During the insertion process of the mounting bracket 100 into the coccyx 211, the coccyx 211 may rub against the adhesive, causing the adhesive to flow in the opposite direction to the direction in which the mounting bracket 100 is inserted into the coccyx 211. In this case, the adhesive may flow through the gap between the mounting bracket 100 and the coccyx 211 to the outer peripheral surface of the coccyx 211, thereby increasing the outer diameter of the coccyx 211, which is not conducive to the miniaturization design of the sound-generating component.
[0077] Therefore, in this embodiment, a glue storage tank 101 is provided on the outer peripheral surface of the mounting frame 100. The opening of the glue storage tank 101 faces the coccyx 211. When the coccyx 211 scrapes against the glue, causing the glue to flow in the opposite direction to the direction in which the mounting frame 100 is inserted into the coccyx 211, the glue storage tank 101 can contain the glue, thereby reducing the risk of the glue flowing to the outer peripheral surface of the coccyx 211 and facilitating the miniaturization design of the sound-generating component.
[0078] In one alternative embodiment, please refer to Figure 7 and Figure 11 The mounting frame 100 includes a cylindrical body 110 and two limiting portions 120. For example, the limiting portions 120 can extend circumferentially along the cylindrical body 110. The cylindrical body 110 has two end faces distributed along its own axial direction. The two limiting portions 120 are respectively provided on the two end faces of the cylindrical body 110. The two basin frames 210 form two tail bones 211 around the outer peripheral surface of the limiting portions 120. The tail bones 211 and the limiting portions 120 are radially limited and engaged with the mounting frame 100.
[0079] The outer peripheral surface of the limiting part 120 is bonded to the inner peripheral surface of the coccyx 211, and the outer diameter of the cylinder 110 is smaller than the outer diameter of the coccyx 211. It should be noted that when this embodiment is combined with the previous embodiment, the outer peripheral surface of the limiting part 120 is provided with the aforementioned glue storage groove 101.
[0080] The specific bonding process is as follows: Adhesive is applied to the outer peripheral surface of the limiting part 120, and the mounting bracket 100 is inserted into the coccyx 211. The bonding is completed after a preset time. During the insertion of the mounting bracket 100 into the coccyx 211, the coccyx 211 may rub against the adhesive, causing the adhesive to flow in the opposite direction to the direction in which the mounting bracket 100 is inserted into the coccyx 211. This could cause the adhesive to flow through the gap between the cylinder 110 and the coccyx 211 to the outer peripheral surface of the coccyx 211, increasing the outer diameter of the coccyx 211, which is detrimental to the miniaturization design of the sound-generating component. Therefore, in this embodiment, the outer diameter of the cylinder 110 is smaller than the outer diameter of the coccyx 211, thus forming a stepped structure between the outer peripheral surface of the cylinder 110 and the outer peripheral surface of the coccyx 211. One side of the stepped structure has a large accommodating space, and the adhesive flowing to the stepped structure is stored in this accommodating space, reducing the risk of adhesive flowing to the outer peripheral surface of the coccyx 211 and facilitating the miniaturization design of the sound-generating component. It should be noted that the aforementioned accommodating space is formed by the combination of the outer peripheral surface of the cylinder 110 and the end face of the coccyx 211.
[0081] In one alternative embodiment, please refer to Figure 7 The sound-generating unit includes a diaphragm 221, which is disposed in the corresponding frame 210. The two diaphragms 221 are respectively engaged with the two ends of the mounting frame 100 along its own axial direction. That is, the first cavity 201 mentioned above is formed between the two diaphragms 221. Along the axial direction of the mounting frame 100, the two ends of the mounting frame 100 are in contact with the outer peripheral portion of the two diaphragms 221 respectively.
[0082] In this embodiment, along the axial direction of the mounting bracket 100, both ends of the mounting bracket 100 are in contact with the outer peripheral portions of the two diaphragms 221, respectively. That is, the ends of the mounting bracket 100 can stop and limit the outer peripheral portions of the diaphragms 221 along the axial direction of the mounting bracket 100. This effectively restricts the axial displacement of the diaphragms 221, allowing the diaphragms 221 to vibrate in a relatively stable position, thereby enabling stable sound output. Of course, along the axial direction of the mounting bracket 100, both ends of the mounting bracket 100 can also be separately disposed from the outer peripheral portions of the two diaphragms 221; this application does not impose this limitation.
[0083] In one optional embodiment, an anti-rotation structure is provided between the mounting frame 100 and each of the two basin stands 210. The anti-rotation structure is used to restrict the relative movement of the mounting frame 100 and the basin stand 210 along the circumference of the mounting frame 100, preventing relative rotation between the mounting frame 100 and the basin stand 210, and improving the assembly stability of the basin stand 210 and the anti-rotation structure. Exemplarily, the number of anti-rotation structures may be only one set, or the number of anti-rotation structures may include multiple sets; this application does not limit this.
[0084] In one alternative embodiment, please refer to Figure 4 , Figures 8 to 11 The sound-generating unit includes a diaphragm 221, which is disposed within a corresponding frame 210. The two diaphragms 221 respectively mate with the two ends of the mounting frame 100 along its own axial direction. That is, the first cavity 201 mentioned above is formed between the two diaphragms 221. The frame 210 and the diaphragms 221 mate to form a pressure relief cavity 202. The anti-rotation structure includes an anti-rotation protrusion 130 and an anti-rotation groove 203. The anti-rotation groove 203 is disposed in the frame 210, penetrates the frame 210, and communicates with the pressure relief cavity 202. Specifically, the pressure relief cavity 202 is located on the side of the diaphragm 221 opposite to the first cavity 201 mentioned above.
[0085] In this embodiment, the anti-rotation structure includes an anti-rotation protrusion 130 and an anti-rotation groove 203. The anti-rotation groove 203 is disposed on the basin frame 210 and is connected to the pressure relief chamber 202 inside the basin frame 210. Thus, the anti-rotation groove 203 connects the pressure relief chamber 202 with the external environment to balance the air pressure inside the pressure relief chamber 202, ensuring the sound quality of the sound-generating component. Therefore, the anti-rotation groove 203 in this embodiment not only prevents relative rotation between the basin frame 210 and the mounting frame 100 but also balances the air pressure inside the pressure relief chamber 202, achieving a dual purpose. Of course, the anti-rotation groove 203 can also be disposed on the mounting frame 100; this application does not limit this.
[0086] In one alternative embodiment, please refer to Figure 7The sound-generating unit includes a diaphragm 221, which includes an annular mounting ring 222 located on its outer periphery. The frame 210 includes a stop portion 212 extending circumferentially along the mounting frame 100. The stop portion 212 is located inside the coccyx 211 and is spaced apart from the coccyx 211. A mounting groove 204 is formed between the stop portion 212 and the coccyx 211. At least a portion of the mounting ring 222 is mounted in the mounting groove 204.
[0087] In this embodiment, the frame 210 includes a stop 212 extending circumferentially along the mounting bracket 100. The stop 212 is located inside the coccyx 211, and a mounting groove 204 is formed between the stop 212 and the coccyx 211. At least a portion of the mounting ring 222 is mounted within the mounting groove 204. The mounting groove 204 provides a relatively fixed and confined space for the mounting ring 222 of the diaphragm 221. During the vibration of the diaphragm 221, the mounting ring 222 can be effectively confined within the mounting groove 204 to prevent excessive radial displacement of the diaphragm 221, ensuring that the diaphragm 221 always vibrates in an ideal position, thereby enabling stable sound output.
[0088] like Figures 1 to 3 As shown in the figure, this application also discloses an ear clip-on earphone, which includes the sound-generating component described in any of the above embodiments. This enables the ear clip-on earphone to have the beneficial effects of the sound-generating component, which will not be described in detail here.
[0089] For example, the ear-clip earphone may further include a sound-generating shell 310, with a sound-generating component disposed within the sound-generating shell 310. The sound-generating shell 310 and the sound-generating component together form a sound-generating member 300, which can be inserted into the user's concha. The ear-clip earphone also includes an abutment for abutting against the back of the user's ear and an ear hook 500 connected to the sound-generating member 300 and the abutment member 400. The ear hook 500 can bypass the user's helix, and the sound-generating member 300 and the abutment member 400 form a clamping state on both sides of the user's helix. The sound-generating member 300 is a sound playback device used to convert electrical signals into sound signals and play them to the wearer. The abutment member 400 forms a clamping state with the sound-generating member 300 to clamp the entire ear-clip earphone onto the user's helix. In some embodiments, the abutment member 400 may contain devices such as a battery or circuit board. Of course, the abutment member 400 may also be used without a battery, and the battery may be installed in the sound-generating member 300.
[0090] In some embodiments, the sound-generating housing 310 may be provided with a sound outlet, which may be located at the bottom of the sound-generating housing 310 and communicate with the first cavity 201; the sound-generating component is located inside the sound-generating housing 310 and cooperates with the sound-generating housing 310 to form a second cavity isolated from the first cavity 201; the anti-rotation groove 203 mentioned above is communicated with the second cavity; and the sound-generating housing 310 is provided with a pressure relief hole that communicates with the second cavity; the pressure relief hole may be located on the side of the sound-generating component 300 near the ear hook 500; the sound generated on one side of the diaphragm 221 of the two sound-generating components is output through the first cavity 201 and the sound outlet, and the sound generated on the other side of the diaphragm 221 of the two sound-generating components is output through the second cavity and the pressure relief hole.
