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...

Abstract

The invention discloses a sound domestication instrument which is characterized by comprising a power supply, a switcher, a switch power supply voltage-reducing circuit, a DC/DC circuit, a timing circuit, an audio frequency generation circuit, a power amplifying circuit and a loudspeaker, wherein the power supply comprises a direct current power supply and an alternating current power supply; and the loudspeaker consists of an enclosure, a voice ring oscillator and a waterproof power cord. In the sound domestication instrument, a signal generator and a signal amplifier are integrated, which reduces the number of instruments and the complicated connecting process of the instruments and is convenient for operation. In addition, the sound domestication instrument can be used for directly setting sound domestication parameters of the waveform of sound, sound source, sound pressure, the frequency of sound, the interval time of pulse and the like, better realize the trapping, control and the drive of fishes and solve the problems of oceanic pastures and freshwater fishing.

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...
