[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 In the described embodiment, a remote control massage vibrating stick control circuit includes a main control chip 1, a motor drive circuit 2, a Bluetooth anti-reverse circuit 3, a switch circuit 4, a display circuit 5, an antenna 6, and a charging circuit 7.

[0019] The motor drive circuit 2 includes a vibration motor, a current-limiting resistor, a pull-down resistor, and a MOSFET. The output terminal of the main control chip 1 is connected to the gate of the MOSFET through the current-limiting resistor. One end of the pull-down resistor is connected between the current-limiting resistor and the gate of the MOSFET, and the other end of the pull-down resistor and the drain of the MOSFET are both grounded. The source of the MOSFET is connected to the negative terminal of the vibration motor, and the positive terminal of the vibration motor is connected to the charging circuit 7. The motor drive circuit 2 also includes a motor protection circuit, which includes a protection diode and a protection capacitor. The cathode of the protection diode is connected to one end of the protection capacitor and the positive terminal of the vibration motor, and the anode of the protection diode is connected to the other end of the protection capacitor and the negative terminal of the vibration motor.

[0020] The Bluetooth anti-reverse circuit 3 includes a Bluetooth module, an anti-reverse diode, and a filter capacitor. One end of the Bluetooth module is connected to the cathode of the anti-reverse diode, and the other end of the Bluetooth module is connected to the main control chip 1. The anode of the anti-reverse diode is connected to the charging circuit 7. One end of the filter capacitor is connected to the cathode of the anti-reverse diode, and the other end of the filter capacitor is grounded.

[0021] The switching circuit 4 includes a power switch, one end of which is grounded and the other end of which is connected to the main control chip 1.

[0022] The display circuit 5 includes an LED indicator, one end of which is grounded and the other end of which is connected to the main control chip 1.

[0023] The charging circuit 7 includes a rechargeable battery and a battery protection circuit. The battery protection circuit includes a protection resistor and a protection MOSFET. The positive terminal of the rechargeable battery is connected to one end of the protection resistor, the main control chip 1, the motor drive circuit 2, and the Bluetooth reverse protection circuit 3. The other end of the protection resistor is connected to the gate of the protection MOSFET. The drain of the protection MOSFET is grounded, and the source of the protection MOSFET is connected to the negative terminal of the rechargeable battery.

[0024] like Figure 2 As shown, the specific circuit principle is as follows:

[0025] It uses DC current charging with a charging voltage of 5V. The power is supplied to the Bluetooth module chip (controlled by the main control chip U1) LDOIN through the anti-reverse diode (D1) and filtered by the filter capacitor (C1), and then to charge the rechargeable battery.

[0026] Charging management uses a main control chip (U1 detection) to detect the rechargeable battery level. Once fully charged, it shuts down the MOSFET (protection resistor R5, protection MOSFET Q2) to prevent overcharging. The main control chip (U1 detection) also prevents the battery from being used when the voltage is below 3V to prevent over-discharge.

[0027] The vibration motor is controlled by a Bluetooth module chip (U1). The Bluetooth module chip sends a signal that turns on the MOSFET (Q1) through the current limiting resistor R1 and the pull-down resistor R4, thereby driving the vibration motor.

[0028] The principle of this control circuit is:

[0029] Vibration is achieved by controlling the frequency of the vibration motor's rotation using high and low level driving (U1 control), and various different modes are formed by adjusting the vibration motor's frequency.

[0030] Press and hold the power switch (S1) for 2.4 seconds to turn on the device. After powering on, the vibration motor will automatically output power for 1 second, then stop outputting power when there is no further action. At this time, the LED indicator (L1) will remain lit. After a 3-second delay, the device will enter sleep low-power mode.

[0031] Standalone mode: After powering on, the LED indicator light stays on. A short press of the power switch can cycle through different modes.

[0032] Remote Mode: After powering on, the LED indicator light stays on; turn on Bluetooth – mobile app – connect via Bluetooth; the LED indicator light flashes quickly after a successful Bluetooth connection. The product can be remotely controlled wirelessly via the mobile app, which offers four modes: Classic Mode, Swipe Mode, Shake Mode, and Share Remote Mode. Classic Mode offers the same various vibration modes as the standalone mode; Swipe Mode controls the vibration motor by swiping the mobile screen; Shake Mode controls the vibration motor by shaking the mobile device; and Share Remote Mode allows you to share the remote with others. The control signal in remote mode is sent from the mobile device via the Bluetooth module to the main control chip, which then sends the signal to the vibration motor for output.

[0033] The LED indicator (L1) breathes while charging and remains lit when fully charged.
