Abstract

The invention discloses an agriculture electric agricultural chemical spraying device capable of enabling convenient mixing of agricultural chemicals. The invention relates to a jellyfish driving infrasonic wave acoustic generator which is technically characterized in that an electric driver suspending support is fixedly mounted at a center of a bottom part of a water resistant and a pressure resistant cavity, a heat exchanger is mounted outside the electric driver, a vibrating wire coil is mounted at the middle of a magnetic gap of the electric driver, the vibrating wire coil is adhered to a water resistant vibrating diaphragm and a damper, the water resistant vibrating diaphragm and a water resistant folding ring are connected in a seamless manner and are fixedly mounted on a driver basin rack, the driver basin rack and the water resistant and a pressure resistant cavity are fixedly mounted together, a watertight pressing ring is mounted on an edge of the water resistant folding ring, a waterproof biological film is attached on the water resistant vibrating diaphragm and the water resistant folding ring, and the water resistant vibrating diaphragm and the water resistant folding ring are protected via installation of an anti-filing net in a notch of the watertight pressing ring.

Description

technical field [0001] The invention relates to the technical field of underwater sound wave generators, in particular to an infrasonic sound generator for repelling jellyfish. Background technique [0002] An infrasonic sound generator refers to a device that can emit sound waves with a frequency below 20Hz. According to different application media, it is divided into infrasonic sound generators in air and infrasonic sound generators in water. Since the speed of sound in water is 5 times that in air, the wavelength of infrasonic waves in water is the same. The frequency of the infrasonic wave in the air is 5 times, which leads to the diameter of the diaphragm of the infrasonic sound generator in the water to be 5 times that in the air. This feature requires the size of the infrasonic sound generator in the water to be large. On the other hand, to achieve the same sound pressure level, the amplitude of the infrasonic wave is much larger than that of the medium and high frequ...
