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.

Abstract

The invention relates to the technical field of audio recognition and charging control, and specifically discloses a shared charge pal based on audio anti-theft. The shared charge pal includes an audio collecting circuit module, a signal amplifying circuit module, a control module and a power module. The invention further discloses a charging device of the shared charge pal based on audio anti-theft, comprising a pulse generating circuit module, a frequency dividing circuit module and an audio transmitting circuit module. The invention also discloses a control method for the shared charge palbased on audio anti-theft and the charging device, comprising the following steps: S1, transmitting anti-theft audio, and collecting audio of a surrounding environment; S2, converting a sampled audioelectric signal into the amplitude of an audio signal; S3, obtaining an average value of amplitudes of two adjacent second audio signals; and S4, determining whether the difference between the amplitude of a first audio signal and the average value is greater than an anti-theft threshold. The invention has the advantages of simple structure, no need for unified management, low cost, quick installation, easy laying in a wide range, simple process and good user experience.

Description

technical field [0001] The invention relates to the technical field of audio recognition and charging control, in particular to a shared power bank based on audio anti-theft, a charging device and a control method thereof. Background technique [0002] The shared charging treasure industry in the mobile power industry is an important portable mobile power industry. With the rapid popularization and rapid development of smart phones with high resolution, large screen, loaded with a large number of APPs, and faster Soc, the battery power consumption rate has been intensified. In the current environment where the power consumption of mobile phones continues to increase, the development of battery technology is relatively slow, the battery life is generally weak, and it is inconvenient to carry power banks with you, in order to solve the above problems, shared power banks came into being. [0003] The current mainstream shared charging treasure is equipped with a huge managemen...
