Multifunctional starting circuit and Bluetooth product

The utility model discloses a multifunctional starting circuit and a Bluetooth product. The multifunctional starting circuit comprises a key circuit, an NFC circuit, a charging circuit, a main chip and a power supply conversion circuit used for supplying power for the main chip. The enabling end of the power supply conversion circuit receives starting signals output through the key circuit, the NFC circuit and the charging circuit, when one path of the starting signal is in a high level state, the power supply conversion circuit operates in an enabling mode and outputs a working power supply to the main chip, after the main chip is powered on, the starting signal of the high level is output to the enabling end of the power supply conversion circuit, and the power supply conversion circuit is maintained to continue to operate in an enabling mode. The multifunctional starting circuit is simple in structural design, small in use quantity of components, low in hardware cost, capable of obviously saving the use ar
