[0064] The pin principle is as follows:

[0065] 1. Power supply pins: such as DCVDD14, WFVDD14, IOVDD, etc., provide stable power input for different modules of the chip; when connecting power supply pins, it is usually necessary to use filter components such as capacitors to filter out power supply noise and ensure stable operation of the chip.

The other ends of the capacitors C8, C9, and C7 are grounded, and the other end of the resistor R17 is connected to the WFVDD14 pin of the main control chip U5.

[0074] In the main control MCU, crystal oscillator Y1 provides a 24MHz frequency, connected to the XOSC0 and XOSC1 pins of the main control chip U5, providing the operating clock signal for the internal digital circuits and ensuring that each functional module of the chip operates according to the correct timing. The power input unit provides a 5V input power through the power supply module, which is divided by resistors R16 and R19 and connected to the PA7 pin on the main control chip U5 to detect whether the power supply is plugged in. After being filtered by a series of capacitors, resistors, and inductors, the 5V power supply generates DCVDD14 and WFVDD14 power signals, which power the main control chip U5 and other circuit modules. Among them, the capacitors and inductors form a filtering circuit to filter out high-frequency noise in the power supply, making the power supply more stable. In addition, capacitors of different capacitance values ​​are used in multiple places for power supply filtering to ensure the purity of the power supply and provide a stable DC voltage for the chip and other circuits.

[0075] Further, see Figure 3 The MIC module includes a first MIC unit and a second MIC unit, both of which are connected to the main control chip U5.

[0076] Furthermore, the first MIC unit includes a microphone interface J2, a capacitor C12, a resistor R21, a capacitor C13, a resistor R25, a capacitor C16, and a capacitor C18.

[0077] Furthermore, the second MIC unit includes a microphone interface J4, a capacitor C14, a resistor R19, a capacitor C15, a resistor R26, a capacitor C17, and a capacitor C19. The capacitor C14 and the resistor R19 are connected in series.

The other ends of the capacitors C15 and C19 are both connected to the main control chip U5.

[0078] This module is equipped with two microphone input units. Through reasonable power filtering, differential signal input, signal coupling, and filtering, it can effectively acquire audio signals, enhance useful information, suppress environmental noise, and clearly pick up sound even in noisy environments, transmitting relatively pure audio signals to subsequent audio processing chips.

[0079] The working principle of this module is as follows:

[0080] 1. Power Supply Section: ACVDD provides power to the circuit. Capacitors C12 and C14, along with resistors R21 and R22, form an RC filter circuit. C12 and C14 are used to filter out high-frequency noise in the power supply, while R21 and R22 act as current limiters and voltage dividers, making the power input to the microphone circuit more stable and pure.

[0081] 2. Microphone Connection: J2 and J4 are microphone jacks for connecting the microphone. M1+ and M1- are the microphone's differential input pins. This differential input method effectively suppresses common-mode noise and improves the quality of audio signal acquisition. Capacitors C16 and C17 act as DC-blocking and AC-passing capacitors, preventing DC signals from affecting the microphone's operation while allowing AC audio signals to pass smoothly.

[0082] 3. Signal Output: The audio signal captured by the microphone is coupled to the MICDP pin through capacitors C12 and C15. C15 and C13 are also DC blocking capacitors, transmitting the audio signal output from the microphone to the subsequent audio processing circuit. The circuits composed of resistor R24 ​​and capacitor C18, and R25 and capacitor C19, can be used for audio signal filtering or impedance matching to further optimize the audio signal.

[0083] Further, see Figure 4-6 The speaker module includes a speaker interface J5, an audio power amplifier chip U6, a headphone conversion unit, and a headphone interface J6. The audio power amplifier chip U6 is connected to the main control chip U5, the speaker interface J5 is connected to the audio power amplifier chip U6, and the headphone interface J6 is connected to the audio power amplifier chip U6 through the headphone conversion unit.

[0084] Furthermore, the headphone conversion unit includes a transistor Q4 and a MOSFET Q3.

The drain terminal of the MOSFET Q3 is connected to the speaker interface J5 through the audio power amplifier chip U6, and the source terminal of the MOSFET Q3 is connected to the power input signal.

[0085] In this module, speaker interface J5 is used to install a speaker; audio power amplifier chip U6 can amplify weak audio signals to drive the speaker; headphone interface J6 is used to install headphones; the headphone conversion unit can switch between headphones and speakers. When headphones are plugged in, pins 1 and 4 of headphone interface J6 are connected, and AUX_EN is low. When transistor Q4 is high, the circuit is turned on, AUX_EN is low, Q4 is turned off, and then MOSFET Q3 is turned off. Q3 is connected to the power supply terminal of the speaker at pin 6, thus realizing the switching of the speaker. This achieves the effect of turning off the speaker when headphones are plugged in and restoring the speaker to normal function when headphones are unplugged.

[0086] Further, see Figure 7 The FLASH module includes a flash memory chip U4 and a filter capacitor C6. The flash memory chip U4 is connected to the main control chip U5, and the filter capacitor C6 is connected to pins 7 and 8 of the flash memory chip U4.

One end of pull-up resistor R23 is connected to the source (S) of the PMOS transistor Q2, and the other end is connected to the gate (G) of the PMOS transistor Q2. The display interface J3 is used to connect to a 1.54-inch LCD or OLED screen for power control and screen communication. Q2 is a PMOS transistor; when its gate is pulled up to 3.3V by R23, the MOS transistor is off; when its gate is pulled low to ground, Q2 is on. The screen and the main control MCU communicate via the SPI protocol. When the main control program performs a theme upgrade, the main control sends information to the screen, and the screen interface changes to display the new theme.

[0090] In this module, the charging interface USB1 is used to connect to an external power adapter or USB-powered device, and the battery J1 is used to power the product. The charging management chip U1 is model AK4056H. The 5V power supply is filtered by a filter circuit composed of resistor R6 and capacitor C5 to remove high-frequency noise from the power supply, making the power input to the charging chip cleaner and more stable. Pin 4 of the charging management chip U1 is connected to the filtered 5V power supply to provide the chip with the power required for operation. Pin 5 is used to set the charging current. By connecting an external resistor to ground, the charging current can be determined according to the formula. Pin 2 is used for grounding. Pin 1 is used for charging status indication.

The low-power control chip U2 is connected to the main control chip U5, and the MOSFET Q1 and button KEY2 are both connected to the low-power control chip U2. When button KEY2 is pressed, a low-level signal powers on the device; when the button is released, a high-level signal is input, at which point the MOSFET is deactivated, and the device enters low-power mode.

[0092] Furthermore, the low-power control chip U2 is model NY8A051H, an 8-bit EPROM microcontroller manufactured by Jiuqi Technology.

[0093] Further, see Figure 11 The LED module includes LED2 and a current-limiting resistor R18, which are connected in series to the power signal VCC. R18 is a 1KΩ resistor that limits the current and is connected in series with LED2 to limit the current passing through LED2 and prevent excessive current from burning out LED2.

[0094] Further, see Figure 12The switch module includes switches KEY1 and KEY3, current-limiting resistors R1 and R12.

Switches KEY1 and KEY3 limit the current in the circuit to prevent excessive current from damaging circuit components during button operation. The "ON / OFF" signal is connected to pin 1 of the button through resistor R2. When the button is not pressed, the "ON / OFF" signal is disconnected from ground; when the button is pressed, the "ON / OFF" signal is shorted to ground.
