Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0034] Embodiment 1

[0035] In this embodiment of the present application, as Figure 1 shown, a LED lamp control circuit controlled by patting is provided, including a patting sensing sensor MIC1, a control chip U1, and a LED lamp group D1LED, D2LED, D3LED, D4LED, D5LED, D6LED, D7LED, and D8LED.

[0036] The first pin of the patting sensing sensor MIC1 is connected to the power supply VCC through the third resistor R5. The power supply VCC is a battery, specifically a 3.7V lithium battery. And the first pin of the patting sensing sensor MIC1 is connected to the base of the second triode Q2 through the fourth resistor R6. The second pin of the patting sensing sensor MIC1 is grounded; the patting sensing sensor MIC1 is a microphone, specifically a microphone with a sensitivity of 35 ± 3dB and a die capacitance C1 value of 2.2K. The microphone is used to detect air - flow changes. When the user pats the product shell, the resistance inside the microphone changes, and through voltage division with the third resistor R5, the changed signal is transmitted to the control chip U1.

[0037] The fourth pin of the control chip U1 is connected to the collector of the second triode Q2, and the fourth pin of the control chip U1 is connected to the power supply VCC via the first resistor R3. The fifth pin of the control chip U1 is connected to the base of the first triode Q1 via the second resistor R4. The first triode Q1 is an S8050, and the second triode Q2 is an NPN transistor. The second and third pins of the control chip U1 are connected to the second and third pins of the switch S1. The first pin of the control chip U1 is connected to the power supply VCC, and there is a capacitor C1 at the first pin of the control chip U1. The capacitor C1 is an inorganic dielectric capacitor, specifically a ceramic capacitor with a capacitance value of 104pF. The eighth pin of the control chip U1 is grounded. The first resistor R3 and the fourth resistor R6 are 9.1M resistors, the third resistor R5 is a 33K resistor, and the second resistor R4 is a 1.8K resistor. The control chip U1 is used to detect the signal of the microphone and output high-level pulse signals with different duty cycles according to the signal, controlling the conduction and cut-off of the first triode Q1, so as to realize the adjustment of the brightness of the LED lamp group. The first resistor R3, the second resistor R4, the third resistor R5, the fourth resistor R6, and the capacitor C1 are used to adjust the parameters of the circuit to ensure the stability and reliability of the circuit. The first triode Q1 and the second triode Q2 are used to amplify the signal output by the control chip U1 and drive the LED lamp group (described below) to emit light.

[0038] The positive pole of the LED lamp group is connected to the power supply VCC, and the negative pole of the LED lamp group is connected to the collector of the first triode Q1. The LED lamp group is composed of multiple LEDs connected in parallel. D1LED, D2LED, D3LED, D4LED, D5LED, D6LED, D7LE, and D|8LED form the LED lamp group, and LEDs with different colors and brightness can be selected according to needs.

[0039] Embodiment 2

[0040] This Embodiment 2 is another improvement based on Embodiment 1, and the beat perception sensor MIC1 is a vibration switch.

[0041] The vibration switch can also achieve the effect of beat perception. Compared with the microphone, it has the following advantages: simple structure, relatively simple design and manufacturing, high reliability, not easily affected by external interference, stable and reliable operation, and low cost.

[0042] Figure 2 As shown, it is the charging interface circuit of the present utility model, used to charge the power supply. Among them, USBI represents the USB interface, specifically the TYPEC interface, used to connect external USB devices, such as power banks and mobile phone chargers, etc.; VBUS represents the power bus, providing 3.7V of electricity to the power supply; GND represents the ground; R8 and R9 are two 5K1 resistors, used for current limiting and voltage division. [[ID=]17]

[0043] Figure 3As shown, it is the lithium battery charging management circuit of the present utility model, which has status indication and power management functions. Specifically, the TP4057 chip is used to manage the charging of the lithium battery, including providing a stable power output (VDD), power bus (VBUS) control, and standby mode (STBY) control to ensure the safe charging of the battery; the green light-emitting diode (DIO GREEN) and the red light-emitting diode (D9 RED) are used to indicate the charging status, with green indicating the charging is completed and red indicating charging in progress or a fault occurring.

[0044] Working principle: When the toggle switch S1 is toggled, the circuit starts to work. When the control chip U1 detects that the level of pin 2 or pin 3 is pulled low, a 10% high-level pulse signal with a frequency of 100KHz will be output from pin 5 and given to the first triode Q1 via the second resistor R4. At this time, the base of the first triode Q1 will receive a continuous electrical signal higher than 0.7V, causing the first triode Q1 to operate in the amplification state. At the same time, the base of the first triode Q1 will receive a small current (affected by the duty cycle) through the second resistor R4, resulting in a certain current in the collector of the first triode Q1, turning on the LED light group.

[0045] When the tapping sensing sensor MIC1 detects a tapping signal, the internal resistance changes. After voltage division with the third resistor R5 and given to a high-level signal to the second triode Q2 via the fourth resistor R6, the level of pin 4 of the control chip U1 is reversed. After the control chip U1 recognizes the level reversal signal, a high-level pulse signal with a different duty cycle is output from pin 5 of the control chip U1 and given to the first triode Q1 via the second resistor R4. Since it is a continuous signal, after passing through the second resistor R4, the resulting currents are different and act on the base of the first triode Q1, causing the brightness of the LED light group to change.

[0046] The above is only the preferred embodiment of the present application and does not impose any formal restrictions on the present application. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present application, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present application. Therefore, all equivalent changes made according to the shape, structure, and principle of the present application without departing from the content of the technical solution of the present application should be covered within the protection scope of the present application.
