Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further：
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of bluetooth Magnetic sucking switch control circuit, blue applied to bluetooth earphone
Tooth earphone includes two earphone heads, and bluetooth earphone here is generally bell-type, and general two earphone heads are covered on respectively when using
On ear.Being provided with the two earphone heads can mutually adhesive between magnet, two magnet.Indigo plant of the present utility model
Tooth Magnetic sucking switch control circuit includes Bluetooth chip, key circuit and control circuit, and Bluetooth chip has the first PIO mouthfuls
PIO21, the 2nd PIO mouthfuls of PIO17, the 3rd PIO mouthfuls of PWR_HOLD, the control circuit include resistance R8, resistance R9, resistance
R10, resistance R11, resistance R12, resistance R13, resistance R14, electric capacity C21, electric capacity C22, electric capacity C23, electric capacity C24, electric capacity C25,
Metal-oxide-semiconductor Q1 and switch S2, one end of resistance R9 one end, electric capacity C22 one end and electric capacity C23 with the first PIO mouthfuls of PIO21
Connection, the resistance R9 other end and the electric capacity C22 other end are grounded, electric capacity the C23 other end, resistance R8 one end and electric capacity
C21 one end is by switching S2 connection external power sources BAT+；The resistance R8 other end and the electric capacity C21 other end are grounded；
Resistance R10 one end connects the 2nd PIO mouthfuls of PIO17, and resistance R14 one end connects the 3rd PIO mouthfuls of PWR_HOLD, R10 resistance
One end of the other end, the resistance R14 other end and resistance R11 by electric capacity C24 connection metal-oxide-semiconductors Q1 drain electrode, resistance R12's
One end connection metal-oxide-semiconductor Q1 drain electrode, the resistance R11 other end and the resistance R12 other end are grounded, and metal-oxide-semiconductor Q1 source electrode leads to
Cross resistance R13 connection electric capacity C21 one end, metal-oxide-semiconductor Q1 grid connection external power source BAT+.Electric capacity C25 is attempted by metal-oxide-semiconductor Q1
Drain and gate.The model of Bluetooth chip is preferably CSR8635.
