| description | The utility model discloses an audio directional sensor based on a directional sound, which comprises a radiation board, a resonance sheet, a chip, a substrate, a protective sheet, a protective cover and a shielding board. The audio directional sensor is characterized in that the radiation board, the resonance sheet, the chip and the substrate are sequentially adhered to form a core component, a positive pole of the chip is connected with a pin standing for a positive pole of the substrate, a negative pole of the chip is connected with a pin standing for a negative pole of the substrate, the protective sheet is disposed on the upper portion of the core component, the protective sheet and the core component are simultaneously embedded inside the protective cover, and the shielding board is tightly jogged with the protective cover and connected with the pin standing for the negative pole of the substrate. The audio directional sensor is particularly adaptable to ultrasonic sensor products with identical phase, |
