The invention discloses an ultra-low power consumption underwater sound releaser which comprises a step-down circuit module, a microprocessor module and a signal amplification detection module. The step-down circuit module is used for reducing input voltage and supplying power to the microprocessor module and the signal amplification detection module; the signal amplification detection module comprises an instrument operational amplifier, an operational amplifier and a detection circuit; the instrument operational amplifier, the operational amplifier, the detection circuit and the microprocessor module are electrically connected in sequence, a weak sound wave signal is sent to the detection circuit after being amplified by the instrument operational amplifier and the operational amplifier in sequence, and the detection circuit generates a low-level pulse signal after receiving a signal within a preset range. The microprocessor module in a dormant state is awakened through a low-level pulse signal; low-power-consumption components are adopted, a circuit for awakening the microprocessor through sound waves is built, the overall power consumption of the awakening circuit is only 2 milliwatts, the circuit is simple, and the area of a circuit board can be effectively saved.
