AI Technical Summary
Existing voiceprint sensors cannot function properly because rainwater can enter the internal electronic circuitry when it rains due to their non-sealed state.
An acoustic signature sensor structure was designed, comprising a waterproof housing, a sound-permeable element, and an integrated circuit board. The sound-permeable element is located outside the waterproof housing and covers the through-hole, allowing only sound to enter. The integrated circuit board inside the waterproof housing processes the sound and prevents rainwater from entering.
This effectively prevents rainwater from entering the sensor and damaging the electronic circuitry, ensuring that the sensor works normally in humid environments.
