Abstract
Description
Technical Field
[0001] This application belongs to the technical field of electronic products, specifically relating to an earphone assembly. Background Technology
[0002] When using true wireless (TWS) earbuds in daily life, oil, earwax, and dust from the ears can accumulate on the earbuds, especially on the sound outlet mesh. Over time, this buildup can cause significant problems. It affects sound quality and can also breed bacteria, impacting the earbuds' health and usability. Therefore, it's necessary to clean the sound outlet mesh regularly.
[0003] To clean the oil stains on the mouthpiece, you need to wipe it with an alcohol swab. This method is effective for large solid dirt on the surface and can also disinfect. However, this method cannot clean sticky earwax such as earwax or dirt deep inside the mesh.
[0004] In addition to wiping with alcohol swabs, electrostatic adsorption or ultraviolet light can also be used for sterilization. However, neither electrostatic adsorption nor ultraviolet light sterilization can clean sticky earwax. Utility Model Content
[0005] The purpose of this application is to provide an earphone assembly that can solve the problem of not being able to clean earwax from the mouthpiece mesh.
[0006] To solve the above-mentioned technical problems, this application is implemented as follows:
[0007] This application provides an earphone assembly, including: earphones and a charging case;
[0008] The earphone includes an earphone body and an electromagnetic coil. The earphone body is provided with a sound outlet mesh, and the electromagnetic coil is disposed on the sound outlet mesh and electrically connected to the earphone's processor.
[0009] The charging case includes a magnetic component;
[0010] When the earphones are placed in the charging case, the electromagnetic coil and the magnetic component are correspondingly arranged and interact with each other, so that the electromagnetic coil drives the sound outlet mesh to vibrate, causing dirt on the sound outlet mesh to fall off.
[0011] In this embodiment, when the earphone is placed in the charging case, the electromagnetic coil is positioned corresponding to the magnetic component and located within the magnetic field range generated by the magnetic component. Thus, when the earphone's processor transmits a signal to the electromagnetic coil, the electromagnetic coil can cause the sound outlet mesh to vibrate under the magnetic field of the magnetic component, thereby causing earwax on the sound outlet mesh to fall off, effectively alleviating the problem of earwax adhering to the sound outlet mesh and affecting sound effects and user health.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0023] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.
[0024] refer to Figures 1 to 4 This application discloses an earphone assembly, which includes earphones 10 and a charging case 20. The earphones 10 can be placed in the charging case 20 for charging, and the charging case 20 also serves to contain and protect the earphones 10.
[0025] The earphone 10 may include an earphone body 11 and an electromagnetic coil 12. The earphone body 11 is provided with a sound outlet mesh 1111. The sound outlet mesh 1111 is located at the sound outlet of the earphone body 11. When the earphone body 11 is working normally, the sound it generates can be transmitted outward through the sound outlet and the sound outlet mesh 1111 for the user to listen to.
[0026] Considering that prolonged use of the headphones 10 may cause dirt, such as earwax, dust, and impurities, to adhere to or accumulate on the sound outlet mesh 1111, this dirt can clog the sound outlet mesh 1111, resulting in poor sound quality of the headphones 10 and affecting the user experience. Furthermore, the presence of dirt can easily breed bacteria, which can have an adverse effect on the user's health when the headphones 10 are worn on the ears.
[0027] Based on the above, in this embodiment of the application, the electromagnetic coil 12 is disposed on the sound outlet mesh 1111, and the electromagnetic coil 12 is also electrically connected to the processor 1121 of the earphone 10, such as... Figure 3 As shown. Based on this, when the earphone 10 needs to be cleaned, the processor 1121 of the earphone 10 can transmit signals of different frequencies to the electromagnetic coil 12, thereby turning on the electromagnetic coil 12.
[0028] Optionally, the signal output by the processor 1121 can be a sinusoidal signal of different frequencies, such as an AC signal, so that the AC signal, when applied to the electromagnetic coil 12, can generate an alternating current within the electromagnetic coil 12. For example, the frequency of the sinusoidal signal transmitted by the processor 1121 can be 10Hz, 20Hz, 10000Hz, 40000Hz, etc., and of course, other frequencies are also possible; no specific limitation is made here. Furthermore, the duration of signal transmission by the processor 1121 can be controlled by software.
[0029] In addition, the charging case 20 may include a magnetic component 22, which can generate a magnetic field at the charging case 20. Thus, when the earphone 10 is placed in the charging case 20, the electromagnetic coil 12 and the magnetic component 22 are correspondingly arranged and interact with each other, so that the electromagnetic coil 12 drives the sound outlet mesh 1111 to vibrate, causing the dirt on the sound outlet mesh 111 to fall off under the vibration, thereby achieving the effect of cleaning the sound outlet mesh 111.
[0030] Optionally, the charging case 20 may also include a case body 21, in which the earphones 10 can be placed, and the magnetic component 22 can be disposed inside the case body 21, so that the case body 21 can respectively contain and protect the earphones 10 and the magnetic component 22.
[0031] In this embodiment, the electromagnetic coil 12 is located in the magnetic field generated by the magnetic component 22. Since the electromagnetic coil 12 is energized, it generates alternating Ampere force under the influence of the magnetic field, causing the electromagnetic coil 12 to vibrate. This vibration, in turn, causes the sound outlet mesh 1111 to vibrate. The vibration helps to remove dirt or grime adhering to or accumulated on the sound outlet mesh 1111, achieving a deep cleaning of the mesh. Therefore, it effectively alleviates the problem of earwax adhering to or accumulating on the sound outlet mesh 1111, which affects sound quality and user health.
[0032] refer to Figure 1 In some embodiments, the magnetic element 22 may have an air duct 221, in which the air inlet of the air duct 221 is positioned opposite to the sound outlet mesh 1111 when the earphone 10 is placed in the charging case 20.
[0033] In addition, the earphone assembly may also include a suction assembly 30, which is disposed inside the charging case 20 and has a suction port 321 that can communicate with the air outlet of the air duct 221.
[0034] Based on the above settings, under the action of the suction component 30, a certain negative pressure can be generated in the area around the air inlet of the air duct 221. Under the action of negative pressure, dirt on the sound outlet mesh 1111 can enter the air inlet and be transported through the air duct 221, so that the dirt can enter the suction component 30 and be discharged in sequence through the air outlet and suction port 321, thereby removing the dirt that has fallen off due to vibration and achieving the cleaning effect of the sound outlet mesh 1111.
[0035] In other embodiments, when the earphone 10 is placed in the charging case 20, the suction port 321 can be directly positioned opposite the sound outlet mesh 1111. Based on this, under the action of the suction assembly 30, a certain negative pressure can be generated in the area surrounding the suction port 321. Under this negative pressure, dirt on the sound outlet mesh 1111 can enter the suction assembly 30 through the suction port 321 and be discharged, thereby removing dirt dislodged by vibration and achieving a cleaning effect on the sound outlet mesh 1111.
[0036] Continue to refer to Figure 1 In some embodiments, the suction assembly 30 may include a pump 31 and a suction pipe 32. One end of the suction pipe 32 has a suction port 321, and the other end of the suction pipe 32 communicates with a through hole 211 in the charging box 20. The pump 31 is located within the suction pipe 32. Based on this, under the action of the pump 31, a certain negative pressure can be generated in the area surrounding the suction port 321, so that dirt on the sound outlet mesh 1111 can be directly sucked away through the suction port 321, or the dirt on the sound outlet mesh 1111 can be sucked away through the air duct 221 provided in the magnetic component 22, achieving a cleaning effect on the sound outlet mesh 1111.
[0037] Optionally, the through hole 211 of the charging case 20 can be used as a vent, through which gas carrying dirt in the suction pipe 32 can be discharged. In addition, the through hole 211 of the charging case 20 can also be used as a clearance hole, through which the other end of the suction pipe 32 can extend outside the charging case 20, so as to directly discharge the gas carrying dirt.
[0038] Furthermore, a filter screen can be installed inside the suction pipe 32 to filter the gas inside the suction pipe 32, thereby removing dirt from the gas and effectively mitigating the adverse environmental impact caused by the direct discharge of dirt. Of course, when the other end of the suction pipe 32 is connected to the through hole 211, the filter screen can also be installed at the through hole 211, which can also filter dirt.
[0039] In some embodiments, the electromagnetic coil 12 may be disposed in the inner edge region of the sound outlet mesh 1111, such as... Figure 3As shown. Based on this, on the one hand, it can effectively prevent external dirt from adhering to the electromagnetic coil 12, and on the other hand, the mesh cloth 1111 at the sound outlet can also shield and protect the electromagnetic coil 12, preventing the electromagnetic coil 12 from being exposed and affecting its appearance or being touched.
[0040] Optionally, the sound outlet mesh 1111 can have a double-layer structure, and the electromagnetic coil 12 can be disposed between the double layers; or, the electromagnetic coil 12 can be directly fixed to the inner side of the sound outlet mesh 1111. Of course, the inner side of the sound outlet mesh 1111 can also be provided with a groove, and at least a portion of the electromagnetic coil 12 is embedded in the groove.
[0041] To ensure the stability and firmness of the installation of the electromagnetic coil 12, the electromagnetic coil 12 and the sound outlet mesh 1111 can be fixed with glue. This can effectively prevent the electromagnetic coil 12 from vibrating and falling off, thus ensuring the stability and firmness of the installation of the electromagnetic coil 12.
[0042] In addition, the electromagnetic coil 12 is located at the edge of the sound outlet mesh 1111, which can effectively reduce the sound blocking effect of the electromagnetic coil 12, thereby alleviating the problem of the electromagnetic coil 12 blocking the sound and affecting the sound effect.
[0043] In some embodiments, the electromagnetic coil 12 may have internal resistance, which can be used to heat the sound outlet mesh 1111 when the electromagnetic coil 12 is energized. Specifically, due to the presence of internal resistance, the electromagnetic coil 12 generates Joule heat when energized. The Joule heat is transferred to the sound outlet mesh 1111 to heat and dry the adhering and accumulated dirt, thereby facilitating the removal of dirt.
[0044] Optionally, the wire diameter of the electromagnetic coil 12 can range from 0.05mm to 0.1mm, for example, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, and 0.1mm. Of course, other values are also possible, and no specific limitation is made here. Using an electromagnetic coil 12 with the above-mentioned wire diameter range can reduce the space occupied by the electromagnetic coil 12 at the sound outlet mesh 1111, which is beneficial for reducing the overall volume of the earphone 10. Furthermore, it can also facilitate the vibration of the electromagnetic coil 12, thereby promoting the removal of dirt from the sound outlet mesh 1111.
[0045] The electromagnetic coil 12 can have at least 50 turns, including, for example, 50, 70, 90, or 100 turns. Of course, other numbers of turns are also possible, and no specific limitation is made here. It should be noted that the more turns the electromagnetic coil 12 has, the higher its vibration frequency, which is more conducive to the removal of dirt from the sound outlet mesh 1111. However, more turns also mean a larger volume for the electromagnetic coil 12, which is less conducive to miniaturizing the headphone body 11. Therefore, the number of turns of the electromagnetic coil 12 must be determined by comprehensively considering both the vibration frequency and the volume of the headphone body 11.
[0046] In addition, the impedance of the electromagnetic coil 12 can be no less than 16Ω, such as 16Ω, 18Ω, 20Ω, 24Ω, etc. Of course, it can also be other values, which are not specifically limited here.
[0047] In some embodiments, the headphone body 11 may include a motherboard 112, and a processor 1121 may be disposed on the motherboard 112. The motherboard 112 is used to transmit sinusoidal signals of different frequencies to the electromagnetic coil 12 through the processor 1121. Based on this, the electromagnetic coil 12 can be energized, so that the electromagnetic coil 12 generates an Ampere force under the action of the magnetic field generated by the magnetic component 22, thereby realizing the vibration of the electromagnetic coil 12. Of course, the electromagnetic coil 12 can also be powered by other electrical components, not limited to the motherboard 112.
[0048] Optionally, the processor 1121 can be electrically connected to the electromagnetic coil 12 through an output interface provided on the motherboard 112, wherein the output interface can be an I / O port, etc.
[0049] In some embodiments, the headphone assembly may include two earphones 10, namely, a left earphone and a right earphone; correspondingly, the charging case 20 may include two magnetic elements 22, and when the two earphones 10 are respectively placed in the charging case 20, the electromagnetic coils 12 of the two earphones 10 are respectively disposed with respect to the two magnetic elements 22. Based on this, the vibration of the two electromagnetic coils 12 can be used to vibrate and clean the sound outlet mesh 1111 of the two earphones 10, thereby alleviating the problem of dirt adhesion or accumulation on the sound outlet mesh 1111.
[0050] In some embodiments, the magnetic element 22 can be a permanent magnet or an electromagnet, and the specific form of the magnetic element 22 can be selected according to the actual working conditions. In some more specific embodiments, the magnetic element 22 can be a ring magnet array, which is directly opposite to the sound outlet mesh 1111.
[0051] In this embodiment of the application, the specific process for cleaning dirt is as follows:
[0052] like Figure 4As shown, when the earphone 10 is placed in the charging case 20 and the lid of the charging case 20 is closed, the fan pump 31 starts, and the earphone 10 inside the charging case 20 detects charging. The processor 1121 of the earphone 10 transmits sinusoidal signals of different frequencies to the electromagnetic coil 12, causing an alternating current to be generated on the electromagnetic coil 12. At the same time, under the magnetic field of the magnetic component 22, the electromagnetic coil 12 drives the sound outlet mesh 1111 to vibrate in accordance with the frequency output by the processor 1121. In addition, the electromagnetic coil 12 can also generate heat to dry the dirt that is stuck or accumulated on the sound outlet mesh 1111, making the dirt easier to remove. The dirt that is dislodged by vibration can be sucked away by the suction component 30. The whole process can last for about 2 minutes, and then the fan pump 31 of the suction component 30 is turned off. Based on the above process, automatic deep cleaning of the sound outlet mesh 1111 can be achieved.
[0053] In summary, this embodiment of the application automatically cleans the dirt on the sound outlet mesh 1111 by causing the electromagnetic coil 12 to vibrate. Furthermore, the suction component 30 sucks up the dirt that has fallen off the sound outlet mesh 1111, thus achieving automatic cleaning of the sound outlet mesh 1111.
[0054] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
