[0034] The features and exemplary embodiments of the various aspects of the present application will be described in detail below with reference to the drawings. The following detailed description is provided to provide further understanding of the present application, and is not intended to limit the present application. The present application can be implemented without some of the specific details, which are well known to those skilled in the art. The following description of the embodiments is merely provided to provide a better understanding of the present application by showing examples of the present application.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0036] With the development of technology and economic progress, smart cards are becoming increasingly common. Smart cards are widely used in finance, transportation, healthcare, and other fields, playing a vital role and bringing great convenience to people's lives. During the use of a smart card, its status can be observed or heard through a card reader. For example, when using a bank card for payment, the card reader will emit a "beep" sound after the payment is confirmed, allowing the user to confirm the payment is complete.

[0037] However, for non-standard card readers, card reader display devices that are damaged, or for people with disabilities, it is often impossible to determine the status of the smart card, causing inconvenience to users.

[0038] To address the technical problems in related technologies, embodiments of this application provide a control circuit for a smart card output component, a smart card, and a mobile smart device. The control circuit for the smart card output component provided in this application embodiment is described below.

[0039] Figure 1 This diagram illustrates the architecture of the control circuit for a smart card output component according to one embodiment of this application. Figure 1 As shown, the control circuit 100 of the smart card output component includes: a power supply module 110 for outputting a DC signal; a safety element 120 connected to the power supply module 110 for determining the operating condition of the smart card and generating a first control signal and a second control signal according to the operating condition; a voltage regulation module 130 connected to the safety element 120 and the power supply module 110 respectively, for performing voltage conversion on the DC signal output by the power supply module 110 according to the first control signal to obtain a target DC signal; and a frequency modulation module 140 connected to the voltage regulation module 130, the safety element 120 and the output component 150 respectively, for converting the target DC signal into a drive signal according to the second control signal and outputting the drive signal to the output component 150.

[0040] The power supply module 110 can supply power to each element in the control circuit 100 of the smart card output assembly, so as to ensure the normal operation of each element.

[0041] The power supply module 110 can output an electrical signal to supply power to each element in the control circuit 100 of the smart card output assembly. The electrical signal output by the power supply module 110 can be a direct current signal.

[0042] The secure element 120 (SE) is activated after receiving the electrical energy provided by the power supply module 110. After being activated, the secure element 120 can determine the working condition of the smart card and generate a first control signal and a second control signal according to the working condition.

[0043] The smart card can have multiple different working conditions, and the response mode of the output assembly 150 can be different under different working conditions. The division of different working conditions in the smart card can be obtained by relevant technical personnel according to various dimensions such as the type and function of the smart card.

[0044] In an example, when the smart card is a bank card, the bank card can be divided into working conditions such as payment, payment completion, and payment failure.

[0045] The voltage regulation module 130 is connected to the secure element 120 and the power supply module 110, so as to convert the direct current signal output by the power supply module 110 into a target direct current signal according to the first control signal output by the secure element 120.

[0046] In an example, the voltage regulation module 130 can include a boost module. The direct current signal output by the power supply module 110 is converted in voltage by the boost module to obtain an amplified target direct current signal.

[0047] In another example, the voltage regulation module 130 can include a step-down module. The direct current signal output by the power supply module 110 is converted in voltage by the step-down module to obtain a step-down target direct current signal.

[0048] The frequency regulation module 140 is connected to the voltage regulation module 130, the secure element 120, and the output assembly 150, so as to adjust the frequency of the target direct current signal according to the second control signal output by the secure element 120, convert the target direct current signal into a driving signal, and output the driving signal to the output assembly 150, so that the output assembly 150 realizes different response modes according to different driving signals.

[0049] In an example, the frequency regulation module 140 can include a driving unit. The driving unit adjusts the frequency of the target direct current signal.

[0050] The driving signal can be a pulse width modulation (PWM) wave. The safety element 120 can control the frequency modulation module 140 to convert the direct current signal output by the voltage modulation module 130 into a PWM wave with different frequencies and duty cycles, so as to control the output component 150.

[0051] In some optional embodiments, the output component 150 can include at least one of a vibration motor 151 or a buzzer 152. The vibration motor 151 includes at least a substrate 1511 and a vibration diaphragm 1512. The buzzer 152 includes at least a substrate 1521, a buzzer sheet 1522, a cavity 1523, and a sound hole 1524.

[0052] In an example, when the output component 150 is the vibration motor 151, the frequency modulation module 140 can output the driving signal to the vibration motor 151, so that the vibration motor 151 can generate different vibration effects according to the driving signal. In an example, if the voltage of the driving signal is high, the vibration motor 151 can generate a stronger vibration feeling, and vice versa, if the voltage of the driving signal is low, the vibration motor 151 can generate a weaker vibration feeling. If the frequency of the driving signal is large, the vibration frequency of the vibration motor 151 is fast, and vice versa, if the frequency of the driving signal is small, the vibration frequency of the vibration motor 151 is slow.

[0053] Figure 2 and Figure 3 all show the structural schematic diagram of the vibration motor 151 provided by an embodiment of the present application, as shown in Figure 2 and Figure 3 The vibration motor 151 includes at least the substrate 1511 and the vibration diaphragm 1512. The vibration diaphragm 1512 can be stacked on the substrate 1511 and connected to the substrate 1511.

[0054] In an example, the substrate 1511 can be any one of metal, plastic, glass, and ceramic.

[0055] In an example, when the vibration motor 151 receives the driving signal sent by the frequency modulation module 140, the vibration diaphragm 1512 of the vibration motor 151 can stretch and contract due to its material properties, thereby generating a vibration feeling.

[0056] In an example, the substrate 1511 and the vibration diaphragm 1512 of the vibration motor 151 can each draw a wire and be connected to the frequency modulation module 140, thereby forming a loop and realizing the vibration function of the vibration motor 151.

[0057] For example, when the output component 150 is a buzzer 152, the frequency modulation module 140 can output the driving signal to the buzzer 152, so that the buzzer 152 can emit different sounds according to the driving signal.

[0058] For example, the buzzer 152 can emit sounds with different volumes and pitches according to the amplitude and frequency of the driving signal.

[0059] In an example, if the voltage of the driving signal is high, the buzzer 152 can emit a louder sound, and vice versa, if the voltage of the driving signal is low, the buzzer 152 can emit a softer sound.

[0060] In another example, if the frequency of the driving signal is high, the buzzer 152 can emit a sharper sound, and vice versa, if the frequency of the driving signal is low, the buzzer 152 can emit a softer sound.

[0061] Figure 4 A structural diagram of the buzzer provided by an embodiment of the present application is shown in FIG. 2. Figure 4 As shown in FIG. 2, the buzzer 152 includes a substrate 1521, a buzzer sheet 1522, a shell 401, and a sound hole 1524. The shell 401 can be used to build a chamber 1523, so that the buzzer sheet 1522 in the chamber 1523 can have a larger vibration space when being driven, and the buzzer sheet 1522 can vibrate and emit sound. Further, the shell 401 and the substrate 1521 can be connected by welding or conductive glue, i.e., connected to a printed circuit board (PCB).

[0062] For example, after receiving the driving signal sent by the frequency modulation module 140, the buzzer sheet 1522 can convert the received electrical energy into mechanical energy, so that the buzzer sheet 1522 can vibrate and generate sound waves. In an example, the buzzer sheet 1522 can be a piezoelectric buzzer sheet, for example, the buzzer sheet 1522 can be made of piezoelectric ceramic material. Silver electrodes are plated on both sides of the ceramic sheet, and after polarization and aging treatment, the ceramic sheet is bonded with a brass sheet or a stainless steel sheet.

[0063] For example, the sound hole 1524 disposed on the shell 401 can be one or more. The position of the sound hole 1524 can be determined by the relevant technical personnel by comprehensively considering the sound emission effect of the buzzer 152 and the specific layout of each element in the circuit.

[0064] In the embodiment of the present application, the buzzer 152 and / or the vibration motor 151 are deployed in the smart card, so that the cardholder can clearly and definitely perceive that the smart card is in different use states. Moreover, the buzzer 152 in the embodiment of the present application is composed of a substrate 1521, a buzzer sheet 1522, a cavity 1523 and a sound hole 1524; and the vibration motor 151 is composed of a substrate and a vibration diaphragm 1512. Such a structure has the characteristics of thinness and small size, and can avoid the problem of excessive size or thickness, which causes the expansion of the volume of the smart card and the inconvenience of the user.

[0065] Further, in the embodiment of the present application, after the power supply module 110 supplies power to the security element 120, the security element 120 can determine the working condition of the smart card, and generate the first control signal corresponding to the voltage adjustment module 130 and the second control signal corresponding to the frequency adjustment module 140 according to the working condition. The voltage adjustment module 130 can convert the direct current signal output by the power supply module 110 into a target direct current signal according to the first control signal; and the frequency adjustment module 140 can convert the target direct current signal into a driving signal according to the second control signal, and output the driving signal to the output assembly 150, so that the output assembly 150 responds to different working conditions, thereby ensuring that the cardholder can clearly and definitely determine the state of the smart card and providing convenience for the cardholder. In addition, the output assembly 150 outputs different response results according to different working conditions of the smart card, which can also increase the interest of the smart card in the use process and improve the use experience of the cardholder.

[0066] Further, in order to realize the conversion of the target direct current signal into the driving signal, as another implementation manner of the present application, the present application further provides another implementation manner of the control circuit 100 of the output assembly of the smart card, which will be described in the following embodiment.

[0067] Figure 5 The architecture diagram of the control circuit 100 of the output assembly of the smart card provided by an embodiment of the present application is shown in FIG. 1. Figure 5 As shown in FIG. 1, the frequency adjustment module 140 includes a first switch unit 141, a first end of the first switch unit 141 is connected to the voltage adjustment module 130, a second end of the first switch unit 141 is connected to the output assembly 150, and a control end of the first switch unit 141 is connected to the security element 120.

[0068] For example, the first switch unit 141 can be a transistor. In an example, the first switch unit can be any one of a metal oxide semiconductor field effect transistor (MOS) and a triode.

[0069] In an example, Figure 6Fig. 1 shows a schematic diagram of a control circuit of an output component of a smart card according to an embodiment of the present application. As shown in Fig. 1, the control circuit of the output component of the smart card comprises a power supply module 110, a security element 120, a voltage regulating module 130 and an output component 150. Figure 6 As shown in Fig. 1, the first switch device can be a first transistor Q1. The first transistor Q1 can be an NPN transistor, and the base of the first transistor Q1 is connected to the security element 120, the collector of the first transistor Q1 is connected to the voltage regulating module 130, and the emitter of the first transistor Q1 is connected to the output component 150. When the security element 120 outputs a high level signal, the first transistor Q1 is turned on; otherwise, when the security element 120 outputs a low level signal, the first transistor Q1 is turned off.

[0070] After the voltage regulating module 130 outputs the target direct current signal, the on-off state of the first transistor Q1 can be controlled, so as to change the frequency of the signal transmitted to the output component 150, such as the buzzer 152 and / or the vibration motor 151, so as to enable the output component 150 to output different response results. In an example, the security element 120 can output high-low level signals with different frequencies to the base of the first transistor Q1, so as to change the on-off state of the first transistor Q1, and thus change the frequency of the signal transmitted to the buzzer 152 and / or the vibration motor 151, so as to change the tone of the buzzer 152 or the vibration frequency of the vibration motor 151.

[0071] In the embodiment of the present application, the on-off state of the first switch device is used to control the frequency of the driving signal transmitted to the output component 150, so as to control the output component 150, and ensure that the output component 150 can output different response results according to the working condition determined by the security element 120, so as to ensure that the cardholder can clearly and definitely determine the state of the smart card 200, and provide convenience for the cardholder.

[0072] In order to provide power for each element in the circuit, as another implementation manner of the present application, the present application further provides another implementation manner of the control circuit 100 of the output component of the smart card, which will be described in the following embodiments.

[0073] For example, the power supply module 110 can be a battery 111 arranged inside the smart card 200; or the power supply module 110 can also be an alternating current power supply unit 112.

[0074] For example, the power supply module 110 can be a battery 111 arranged inside the smart card 200; or the power supply module 110 can also be an alternating current power supply unit 112. Figure 7 Fig. 1 shows a schematic diagram of a control circuit of an output component of a smart card according to an embodiment of the present application. As shown in Fig. 1, the control circuit of the output component of the smart card comprises a power supply module 110, a security element 120, a voltage regulating module 130 and an output component 150. Figure 7 As shown in Fig. 1, the power supply module 110 can be a battery 111, which can be connected to the security element 120 and the voltage regulating module 130 respectively. The battery 111 can supply power to the security element 120, so as to enable the security element 120 to determine the working condition of the smart card 200, and generate the first control signal and the second control signal according to the working condition. In addition, the voltage regulating module 130 can obtain the target direct current signal from the low voltage direct current signal output by the battery 111 through voltage conversion.

[0075] For example, the power supply unit 112 can supply power to each element in the circuit.

[0076] In some optional embodiments, Figure 8 An architecture diagram of the control circuit of the smart card output assembly is shown. As Figure 8 As shown, the power supply module 110 can include a coil 1121 and a rectifier circuit 1122, wherein the coil 1121 is connected to the secure element 120, and the rectifier circuit 1122 is connected to the coil 1121, the secure element 120 and the voltage regulation module 130 respectively.

[0077] For example, the secure element 120 can be powered by the coil 1121, and when there is power in the coil 1121, the rectifier circuit 1122 can convert the power in the coil to obtain power capable of driving the output assembly 150.

[0078] The smart card 200 can achieve the corresponding functions of the smart card by interacting with the card reading device. For example, when the bus card is close to the card reader, the card reader can read the data in the bus card to achieve the payment for taking the bus. In this process, the smart card 200 can obtain energy from the card reading device.

[0079] In an example, the card reading device can be a near field communication (NFC) transmitting device 910. For example, it can be a mobile smart device, a wearable device, a vehicle and the like supporting NFC function. Figure 9 An example of the smart card energy acquisition provided by an embodiment of the present application is shown. As Figure 9 As shown, the NFC transmitting device 910 can generate an alternating magnetic field by deploying an internal circuit when triggering the card reading function. When the smart card 200 is close to the NFC transmitting device 910, the coil in the smart card 200 enters the alternating magnetic field to generate an induced electromotive force, i.e. power. Further, the smart card 200 drives each element in the smart card by the power generated by the coil, so that each element in the smart card can work normally.

[0080] In the embodiment of the present application, the battery 111 is deployed in the smart card, or the coil and the rectifier circuit are set to supply power to each element in the smart card, to ensure the normal work of each element.

[0081] Since the voltage of the direct current signal provided by the power supply module 110 is low, in order to improve the voltage of the direct current signal, as another implementation manner of the present application, the present application further provides another implementation manner of the control circuit 100 of the smart card output assembly, which is described in the following embodiment.

[0082] Figure 10 An architecture diagram of a control circuit of an intelligent card output component is shown. As Figure 10 The voltage regulating module 130 includes an inductor unit 131 connected to the power supply module 110, a second switch unit 132, a first end of the second switch unit 132 connected to the inductor unit 131, a second end of the second switch unit 132 grounded, a control end of the second switch unit 132 connected to the secure element 120, for controlling the state of the second switch unit 132 according to the first control signal received from the secure element 120, the state including a conducting state and a disconnected state, a first unidirectional conducting unit 133, a first end of the first unidirectional conducting unit 133 connected to a second end of the inductor unit 131, a second end of the first unidirectional conducting unit 133 connected to the frequency modulation module 140, and a first voltage stabilizing unit 134, a first end of the first voltage stabilizing unit 134 connected to the first unidirectional conducting unit 133, and a second end of the first voltage stabilizing unit 134 grounded.

[0083] In some optional embodiments, the inductor unit 131 in the voltage regulating module 130 can be a first inductor L1, a first end of the first inductor L1 connected to the power supply module 110, the second switch unit 132 including a transistor Q2, a first end of the transistor Q2 connected to a second end of the first inductor L1, a second end of the transistor Q2 grounded, and a control end of the transistor Q2 connected to the secure element 120, the first unidirectional conducting unit 133 including a diode D1, an anode of the diode D1 connected to the second end of the first inductor L1, and a cathode of the diode D1 connected to the frequency modulation module 140, and the voltage stabilizing unit including a first capacitor C1, a first end of the first capacitor C1 connected to the cathode of the diode D1, and a second end of the first capacitor C1 grounded.

[0084] For example, the transistor Q2 can be any one of a MOS tube or a triode.

[0085] In an example, Figure 11 An architecture diagram of a control circuit 100 of an intelligent card output component is shown. As Figure 11As shown, the voltage regulating module 130 includes a first inductor L1, a transistor Q2, a diode D1 (the diode D1 is exemplarily illustrated as an NPN type transistor), and a first capacitor C1. When the transistor Q2 receives a high level signal sent by the security element 120, the transistor Q2 is turned on, the first inductor L1 is charged by the power supply module 110, and the voltage in the first inductor L1 gradually increases. At this time, the diode D1 is in a reverse bias state, and the first capacitor C1 provides a voltage for the frequency modulation module 140. When the transistor Q2 receives a low level signal sent by the security element 120, the transistor Q2 is turned off, the first inductor L1 starts to discharge, and the diode D1 becomes forward biased, so that the electrical signal output by the first inductor L1 flows to the frequency modulation module 140 and the first capacitor C1, thereby charging the first capacitor C1 and providing an electrical signal for the frequency modulation module 140. It can be understood that when the first inductor L1 starts to discharge, an induced electromotive force opposite to the current direction is generated, which is superimposed on the frequency modulation module 140, thereby increasing the voltage output by the voltage regulating module 130.

[0086] The different working conditions determined by the security element 120 can correspond to different response results of the output assembly 150. The response results are affected by the voltage size. Therefore, the security element 120 can determine the voltage size corresponding to the output assembly 150 according to the working condition, and a first control signal corresponding to the voltage size. The on-off state of the transistor Q2 in the voltage regulating module 130 is adjusted through the first control signal, so as to adjust the voltage size. For example, in the case of Figure 10 In the embodiment of the present application, the rising degree of the output voltage of the voltage regulating module 130 can be adjusted by adjusting the duty cycle of the first control signal, wherein the greater the duty cycle, the higher the output voltage; the smaller the duty cycle, the lower the output voltage.

[0087] In the embodiment of the present application, the direct current signal output by the power supply module 110 is amplified by the voltage regulating module 130, so as to ensure that the output assembly 150 can output the corresponding response result according to the corresponding amplified target direct current signal, and ensure that the cardholder can clearly and definitely determine the state of the smart card 200.

[0088] In some optional embodiments, when the security element 120 establishes a communication connection with the mobile smart device, the security element 120 can receive the control parameter sent by the mobile smart device, and generate the first control signal and the second control signal according to the control parameter and the working condition.

[0089] Exemplarily, the security element 120 can communicate with the mobile smart device when working. The mobile smart device can be a device bound with the smart card. The cardholder can set the relationship between the smart card working condition and the response result of the output assembly 150 in the mobile smart device, and determine the control parameter of the response result corresponding to the working condition.

[0090] In an example, when the output component 150 is the buzzer 152, the cardholder can set different response results corresponding to different working conditions of the bound bank card in the mobile intelligent device. For example, the cardholder can set that in the process of bank card payment, the buzzer 152 emits a short sound to guide the completion of payment, and the buzzer 152 emits a long sound. Wherein, the volume and tone of the short sound and the long sound emitted by the buzzer 152 can be different. Further, the mobile intelligent device can determine the corresponding control parameters according to the response results set by the cardholder.

[0091] In the embodiments of the present application, the first control signal and the second control signal can be generated according to the control parameters set by the user and the working conditions, so as to enable the cardholder to determine the working conditions corresponding to different response results of the output component 150.

By printing the layer 202, the patterns required by the user are printed, which not only improves the aesthetic appearance of the smart card 200, but also enhances the anti-counterfeiting capability of the smart card 200.
