The power supply Vcc is used for supplying electric energy, and the power supply Vcc may be a solar battery or a dry battery, etc., and in this embodiment, the power supply Vcc is a solar battery.
The sound acquisition circuit 1 comprises a first resistor R1 and a sound detection sensor P, wherein a first end of the first resistor R1 is electrically connected with the power supply Vcc, and a second end of the first resistor R1 is electrically connected with a first end of the sound detection sensor P and the first coupling circuit 2; the second end of the sound detection sensor P is grounded.
