[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0035] refer to Figure 1 This is a schematic diagram of a dustproof net cleaning component, for reference. Figure 2This is a schematic diagram of the electrical connections of a dust filter cleaning component, combined with... Figure 1 and Figure 2 The dust filter cleaning component includes:
[0036] Dustproof net 1;
[0037] The first deformable cleaning body 2 is located on the dustproof net 1 and is used to clean objects attached to the dustproof net 1 by means of deformation;
[0038] The controller 3 is connected to the first cleaning body 2 and is used to control the deformation of the first cleaning body 2.
[0039] The dustproof mesh can be a dustproof mesh in the terminal equipment, including but not limited to: a dustproof mesh installed at the sound outlet of the speaker, and a dustproof mesh installed at the earpiece.
[0040] The deformable first cleaning body 2 can be any type of controlled deformable component, and the first cleaning body 2 can deform according to the control of the controller 3. The deformation process of the first cleaning body 2 can be preset, and during deformation, it can deform according to the preset deformation process.
[0041] The structure of the first cleaning body 2 is not limited; it can be fixed to the dustproof net 1, has deformation function, and can deform according to the control of the controller 3. For example, the first cleaning body 2 is a component formed of shape memory material.
[0042] The controller 3 can be any device with control functions, including but not limited to: a central processing unit (CPU) and a microcontroller unit (MCU). The controller 3 can control the deformation of the first cleaning body 2. The controller 3 can be electrically connected to the first cleaning body 2, and the controller 3 can control the first cleaning body 2 through electrical signals. For example, it can output a control signal to control the first cleaning body 2 to deform or stop deforming.
[0043] During the deformation process of the first cleaning body 2, it can come into contact with the object attached to the dustproof net 1, causing the object to move and thus separating the object from the dustproof net 1, removing the object from the dustproof net 1.
[0044] During the deformation of the first cleaning body 2, the first cleaning body 2 can directly contact the object attached to the dustproof net 1 and drive the object to move. Therefore, this method has a high cleaning ability and can improve the cleaning effect on the dustproof net, thereby reducing the debris attached to the dustproof net, reducing the impact on sound output, and thus improving the user experience.
[0045] In one embodiment, the first cleaning body 2 is located on the side of the dustproof net 1 facing the interior of the device in which the dustproof net 1 is located.
[0046] The equipment containing the dustproof net 1 may have through holes, such as sound outlets or other user-defined through holes. The dustproof net 1, located inside the equipment and aligned with these through holes, can block them, thus preventing external debris from entering the equipment and minimizing its impact on the through hole's function. The first cleaning body 2 is located on the side of the dustproof net 1 facing inwards from the equipment. This facilitates the assembly of the first cleaning body 2 and reduces the risk of damage from external factors.
[0047] In one embodiment, the first cleaning body 2 adheres to the dustproof net 1 during the deformation process, which allows the first cleaning body 2 to rub against the debris attached to the dustproof net 1 during the deformation process, thereby removing the debris from the dustproof net 1.
[0048] In one embodiment, the deformation coverage of the first cleaning body 2 during the deformation process is able to cover at least a portion of the dustproof net 1.
[0049] The area covered by the first cleaning body 2 during deformation can be pre-set or determined based on the maximum deformation coverage area during the deformation process of the first cleaning body 2. Different deformation modes may correspond to different deformation coverage ranges.
[0050] During the deformation process of the first cleaning body 2, it can cover part of the dustproof net 1 to achieve the effect of cleaning the dustproof net 1.
[0051] For example, the first cleaning body 2 covers the entire area of the dustproof net 1 during the deformation process, that is, the first cleaning body 2 can completely cover the dustproof net 1 during the deformation process. This can achieve cleaning of the maximum area of the dustproof net 1, thereby maximizing the cleaning area of the first cleaning body 2 and helping to improve the cleaning effect on the dustproof net 1.
[0052] In one embodiment, the deformation state of the first cleaning body during the deformation process includes multiple different preset deformation states. The deformation state may include extreme states and intermediate states during the deformation process. By switching between different deformation states, the cleaning of debris on the dustproof net 1 is achieved.
[0053] refer to Figure 3 This is a schematic diagram of the deformation process of a first cleaning body 2. State 1 is an intermediate state, and states 2 and 3 are two limiting states. The limiting states and intermediate states can be determined based on the properties and performance of the first cleaning body 2.
[0054] In one embodiment, the first cleaning body 2 can be a cleaning body formed of a shape memory material, such as a cleaning body formed of shape memory alloys (SMA). Shape memory materials have a shape memory effect, meaning they can deform after meeting deformation conditions and can also restore their shape, maintaining their integrity during this process.
[0055] The deformation condition can be a temperature condition, where deformation occurs when the temperature is higher or lower than a preset temperature.
[0056] When the first cleaning body 2 is a cleaning body formed of shape memory material, the first control signal output by the controller 3 is a current signal. Since the shape memory alloy is a metal and has resistance, heat will be generated when current flows through it. The generated heat can change the temperature of the first cleaning body 2, thereby causing the first cleaning body 2 to deform.
[0057] For example, the current signal can be a current signal of a preset size. When the current reaches the preset size, the heating efficiency of the first cleaning body 2 can be improved, thereby reducing the time for the first cleaning body 2 to deform and improving the efficiency of the first cleaning body 2 to deform.
[0058] For example, the first control signal is a pink noise signal, which can help to heat up the first cleaning body 2, thereby accelerating the deformation of the first cleaning body 2.
[0059] In one embodiment, the first cleaning body 2 can also be a cleaning body formed of a piezoelectric material. A piezoelectric material can generate a voltage difference when subjected to pressure. Following the reverse logic, applying a voltage signal to the piezoelectric material can cause the first cleaning body 2 to deform. The degree of deformation is positively correlated with the magnitude of the voltage difference; the larger the voltage difference, the greater the degree of deformation, and vice versa.
[0060] In one embodiment, when the first cleaning body 2 is a cleaning body formed of shape memory alloy, the first cleaning body 2 deforms under the control of the controller 3. The controller 3 can apply an electrical signal to the first cleaning body 2, and the current signal flowing through the first cleaning body 2 generates heat. This heat can be used to soften debris attached to the dustproof net 1. The debris that can be softened can include grease or grease mixtures. After these debris are softened, they can be easily removed from the dustproof net 1.
[0061] In one embodiment, the first cleaning body 2 is elongated or cylindrical.
[0062] This example shows a first cleaning body 2 with different shapes, see reference. Figure 3 , Figure 3The first cleaning body 2 shown is a cylindrical filament formed of a shape memory alloy.
[0063] In one embodiment, the first cleaning body 2 is a linear component, which serves as part of the mesh wire in the dustproof net 1 and is used to drive the dustproof net 1 to deform during the deformation of the first cleaning body 2.
[0064] Since the dustproof net 1 is made of multiple mesh cables, in this embodiment, the first cleaning body 2 is incorporated as part of the dustproof net 1. The first cleaning body 2, as a portion of the mesh cables in the dustproof net 1, can cause the dustproof net 1 to deform when it deforms. After the dustproof net 1 deforms, it can exert tensile or compressive forces on objects attached to it, thereby removing the objects from the dustproof net 1.
[0065] In this case, the deformation of the first cleaning body 2 can be a contraction deformation, that is, a contraction length deformation, and a recovery deformation after contraction. During this process, the dustproof net 1 can be gathered and restored, the dustproof net 1 can vibrate, and it is also convenient to clean the objects attached to the dustproof net 1.
[0066] For example, the controller 3 outputs a first control signal, which is used to retract the first cleaning body 2. For instance, when an electric current passes through the first cleaning body, heat is generated, and the first cleaning body 2 retracts its length.
[0067] The controller 3 can also control the first cleaning body 2 to return to its original length. For example, after the controller 3 stops outputting the first control signal, the first cleaning body 2 no longer generates heat, the temperature decreases, and the length returns to its original length before shrinking.
[0068] In one embodiment, reference Figure 2 The dust filter cleaning component also includes:
[0069] The second cleaning body 4 is electrically connected to the controller 3 and faces the dustproof net 1. It is used to generate airflow in the area where the dustproof net 1 is located under the control of the controller 3. The airflow is used to remove objects attached to the dustproof net 1 from the dustproof net 1.
[0070] The structure of the second cleaning body 4 is not limited; it can be a speaker, an air pump, or other structures capable of generating airflow.
[0071] During the process of a loudspeaker being used, it can cause the air to vibrate, thereby generating airflow.
[0072] For example, the airflow direction is away from the second cleaning body.
[0073] The second cleaning body 4 can generate airflow in the area where the dustproof net 1 is located during the process of the first cleaning body 2 deforming and cleaning objects on the dustproof net 1. This airflow can then further clean the objects that the first cleaning body 2 has removed from the dustproof net 1. For example, it can blow the objects removed from the dustproof net 1 by the first cleaning body 2 out of the equipment, reducing the impact on the internal components of the equipment and also reducing the residue on the dustproof net 1.
[0074] By combining the second cleaning body 4 and the first cleaning body 2, the cleaning ability of objects attached to the dustproof net 1 can be improved, thereby improving the cleaning effect.
[0075] The second cleaning body 4 can also work independently, generating airflow in the area where the dustproof net 1 is located, blowing the objects attached to the dustproof net 1 off the dustproof net 1.
[0076] In one embodiment, the controller 3 is further configured to generate a second control signal, which controls the second cleaning body to generate airflow in the area where the dustproof net 1 is located.
[0077] When the second cleaning unit 4 is a speaker, the second control signal can be an audio signal. When the second cleaning unit 4 is an air pump, the second control signal can be a current signal or a voltage signal used for starting and operating the air pump.
[0078] In one embodiment, when the second cleaning body 4 is a speaker, it is electrically connected to the controller 3, and the speaker's sound outlet faces the dustproof mesh 1. This facilitates the airflow generated by the vibration of the air when the speaker is emitting sound to blow towards the dustproof mesh 1, thereby blowing away debris on the dustproof mesh 1, or blowing objects cleaned off the dustproof mesh 1 during the deformation of the first cleaning body 2 out of the device.
[0079] For example, the speaker can be a built-in speaker for playing audio. This allows the original structure of the device to be maintained without altering it, thereby reducing damage to the original structure, lowering costs, and enabling the cleaning of the dust filter 1.
[0080] In one embodiment, the second control signal includes:
[0081] Low-frequency audio signals;
[0082] or,
[0083] Ultrasonic signal.
[0084] Low-frequency audio signals can increase the amplitude of the speaker diaphragm, thereby increasing the vibration amplitude of the air and increasing airflow.
[0085] In one embodiment, when the second cleaning body 4 is an air pump, it is electrically connected to the controller 3, and the air outlet of the air pump faces the dust screen 1. This allows the airflow generated by the air pump to blow in the direction of the dust screen 1, thereby blowing away debris on the dust screen 1, or blowing objects cleaned off the dust screen 1 during the deformation of the first cleaning body 2 out of the equipment.
[0086] In one embodiment, reference Figure 2 The dust filter cleaning component may also include:
[0087] The first signal amplifier 5 is located between the controller 3 and the first cleaning body 2, and is electrically connected to the controller 3 and the first cleaning body 2 respectively.
[0088] The second signal amplifier 6 is located between the controller 3 and the second cleaning body 4, and is electrically connected to the controller 3 and the second cleaning body 4 respectively.
[0089] Both the first signal amplifier 5 and the second signal amplifier 6 can be power amplifiers. Signal amplifiers can help improve the cleaning effect of the first cleaning body 2 and the second cleaning body 4.
[0090] In one embodiment, reference Figure 4 This is a schematic diagram of an electronic device, which includes:
[0091] The frame k has a sound hole j;
[0092] Dustproof mesh 1 is located inside the frame k and aligned with the sound outlet j;
[0093] The dustproof mesh cleaning component in any of the above embodiments.
[0094] Electronic devices can be any type of electronic device with a dustproof screen, such as mobile electronic devices and fixed electronic devices. Mobile electronic devices can include: mobile phones, tablets, laptops, wearable devices, smart home devices, aircraft, etc.
[0095] In one embodiment, the dust filter cleaning component has a first cleaning mode;
[0096] In the first cleaning mode, the first cleaning body 2 in the dustproof net cleaning assembly cleans the dustproof net 1.
[0097] In one embodiment, the electronic device includes a speaker A;
[0098] The dust filter cleaning component has a second cleaning mode;
[0099] In the second cleaning mode, the first cleaning body 2 and the second cleaning body 4 in the dust filter cleaning assembly clean the dust filter 1; wherein, the speaker A serves as the second cleaning body.
[0100] In one embodiment, the electronic device includes a speaker A, and the dust filter cleaning component has a non-cleaning mode;
[0101] In non-clean mode, speaker A is used to play audio that is to be played in the electronic device.
[0102] For example, speaker A may include Figure 4 The components shown are: center magnet (a), horn diaphragm (b), horn front cavity (c), voice coil (d), vent (e), horn rear cavity (f), and horn mouth (g). Dustproof mesh 1 is located at the horn mouth (g).
[0103] Electronic devices may also include:
[0104] The sealing foam h is located between the dustproof mesh 1 and the frame k, and is used to seal the dustproof mesh 1 and the sound outlet j.
[0105] In one embodiment, another example is also provided.
[0106] With the increasing prevalence of smartphones and their diverse usage environments, the demands on phone reliability are constantly rising. Customer complaint analysis reveals that a significant portion of acoustic failure modes, such as complete silence, low volume, and unwanted noise, are caused by foreign matter adhering to and clogging the dust filter. Analysis of the foreign matter composition shows that it is mostly a mixture of human body oils, food grease, cosmetics, and dust. This solution utilizes a shape memory metal (SMA) skeleton, under different driving signals, to heat and soften the foreign matter trapped on the dust filter, causing it to deform and loosen and detach. Simultaneously, the speaker's acoustic airflow propels the foreign matter to the outside of the device, thereby improving speaker reliability and user experience.
[0107] 1) The phone speaker is designed to emit sound from the side.
[0108] 2) The speaker dustproof mesh is located near the sound outlet and is supported by an SMA frame, and is sealed to the phone casing by sealing foam. The first cleaning body 2 may include an SMA frame.
[0109] 3) SMA is a shape memory metal, which has the characteristic of changing into a specific shape under a specific driving current.
[0110] 4) The dustproof net is located on the outside of the SMA frame and can prevent foreign objects from entering the interior.
[0111] 5) The SMA skeleton is rectangular, with a width of 1mm. The middle part is usually diagonally spring-shaped, with a width of 0.5mm.
[0112] 6) The SMA frame and dustproof mesh are attached with double-sided tape.
[0113] 7) The speaker and SMA frame are driven by a smart amplifier.
[0114] 8) When the speaker cleaning function is activated, the controller (such as the platform chip) outputs a signal to the first signal amplifier 5 and the second signal amplifier 6.
[0115] 9) The second control signal includes the signal at the low-frequency resonant point, which makes the speaker work at the maximum amplitude to generate the maximum airflow and ultrasonic waves.
[0116] 10) The first control signal is pink noise, which can quickly change the temperature of the SMA skeleton, thereby changing different shapes.
[0117] 11) When the temperature of the SMA skeleton rises, it will also heat the foreign objects, especially oily foreign objects, which will soften when heated. When deformed, the diagonal movement of the SMA will loosen the foreign objects.
[0118] 12) The SMA frame can be set to three states so that the movement trajectory can fully cover the dustproof mesh surface.
[0119] 13) Soft foreign objects are sent to the outside by the sound wave airflow of the horn, thus completing the removal of stubborn foreign objects.
[0120] 14) In non-speaker cleaning state, the first cleaning body 2 and SMA frame do not work, which does not affect the normal operation of the speaker.
[0121] 15) This solution does not change the original stacking structure.
[0122] 16) Alternatively, the SMA skeleton can also be directly woven into the dustproof net in the form of silk threads, and the dustproof net can be directly twisted to achieve the same effect.
[0123] 17) Alternatively, the SMA skeleton can also be replaced by a piezoelectric film, which can be directly twisted to achieve the same effect as the dustproof net.
[0124] This solution combines three physical methods: heating and softening, powerful scraping, and high-airflow blowing, resulting in a stronger and more thorough cleaning. It also improves speaker reliability and user experience.
