Abstract
Description
technical field
[0001] The invention relates to the field of electronic equipment, in particular to an acoustic acclimation instrument. Background technique
[0002] For some waters with complex geology and tortuous coastlines, ordinary dragging fishing gears such as pulling nets and trawls cannot be used, and fixed fishing gears are also limited. Light and electric fishing is also affected by space, time and their own characteristics (such as propagation distance, etc ) conditions often cannot be applied in these complex and dangerous waters, and selective fishing cannot be achieved for fish of different species, sizes and ages, which poses a hazard to the sustainable development of fisheries. At the same time, in the traditional breeding process, the cultured fish cannot take food quickly after feeding, so that a large amount of bait falls into the bottom of the water through the cage, and the bait is deposited for a long time, causing the pollution of the bait to the wate...
Examples
Embodiment Construction
[0010] like figure 1 and figure 2 As shown, the acoustic acclimation instrument is composed of a power supply, a switch, a switching power supply step-down circuit, a DC / DC circuit, a timing circuit, an audio frequency generating circuit, a power amplifier circuit and a speaker BL, and the circuits are integrated and connected. The power supply can use AC220V power supply or DC12V battery power supply. When using AC power supply, the AC interface outputs DC 12V through the transfer switch K2 and the switching power supply step-down circuit, and then enters the working circuit through the transfer switch K1; when using the DC12V battery power supply, the DC interface enters the working circuit through the transfer switch K1.
[0011] The DC12V power supply enters the working circuit in two ways through the switch K1, and one way enters the DC / DC circuit, and outputs ±35V voltage to supply power to the fourth pin of the high-power audio amplifier integrated circuit 3886 in the...
