Embodiment 1
[0054] like figure 1 As shown, a shared power bank based on audio anti-theft is used in conjunction with smart mobile terminals and / or charging devices. The shared power bank based on audio anti-theft includes an audio acquisition circuit module M1, a signal amplification circuit module M2, a control module M3 and Power supply module M4; one end of the audio acquisition circuit module M1 is electrically connected to one end of the signal amplification circuit module M2; the control module M3 is electrically connected to the other end of the signal amplification circuit module M2; the power supply module M4 is used as the audio acquisition circuit module M1 , the power supply of the signal amplification circuit module M2 and the control module M3;
[0055] The audio collection circuit module M1 is used to collect the anti-theft audio sent by the charging device and / or the ambient audio around the shared power bank based on audio anti-theft and / or the unlock audio sent by the sm...
Embodiment 2
[0059] Embodiment 2 is the further optimization of embodiment 1;
[0060] like figure 2 As shown, the shared power bank based on audio anti-theft also includes a wireless power receiving module M5; the wireless power receiving module M5 is electrically connected to the control module M3 and the power module M4 respectively; the wireless power receiving module M5 is used for receiving and charging The wireless charging power when the charging device corresponding to the treasure is wirelessly charging the shared charging treasure based on audio anti-theft, and obtains the signal of wireless docking between the shared charging treasure based on audio anti-theft and the charging device, so as to wirelessly dock the charging treasure. The signal is transmitted to the control module M3; the wireless power receiving module M5 adopts the principle of electromagnetic induction wireless charging or the principle of magnetic coupling resonance wireless charging to receive wireless char...
Embodiment 3
[0062] Embodiment 3 is the further optimization of embodiment 1;
[0063] like image 3 As shown, the shared power bank based on audio anti-theft also includes a power switch control circuit module M6; the power switch control circuit module M6 is electrically connected to the control module M3 and the power module M4 respectively;
[0064] The power switch control circuit module M6 is used to cut off the output of the charging current of the power module M4 when the control module M3 does not obtain an unlocking instruction and the shared power bank based on audio anti-theft is beyond the safety and anti-theft range of the charging device.
