Actual Sound: (the sounds of dispelling birds)Actual Sound: (the sounds of dispelling birds)

CCTV：In the season of cherry ripening, fruit growers repeat the boring work in the morning and in the evening every day.
Fruit Grower One: you can see, one pie found cherry delicious, it will tell others to fly here,
Host: “really?”
Fruit Grower One: yes, one group after another, they didn’t fly away even you dispel them.
Fruit Grower Two: “I don’t know how to dispel them. They will come back again after a short while”
Host: “That is to say there is no way to do with it.”
Fruit Grower Two: “yes.”

CCTV：The fact that birds always come here is equal to say that our environment is excellent. However, fruit grower cannot afford it. Moreover, some birds are endangered animals, if you hurt them, you will be punished.

Actual Sound: “the sound of hawk”
CCTV: where does the sound come from? Many birds are scared and escape from the fruit garden. Is there a hawk?

Actual Sound: “the sounds of many birds, and then the loudspeaker appears”

CCTV: the sounds are coming from here. It is so similar to reality. It is so clever to dispel birds by broadcasting the sounds of their enemies. That is the digital bird repeller, which is developed by Dr. Zheng Wenggang Birds are not easy to be cheated. If the birds are adapted to these sounds, they will fly here again.
Zheng Wengang: the digital bird repeller integrates ten bird sounds. According to different places and different birds, we can broadcast different sounds. And we can broadcast the sound randomly, which can puzzle birds.

CCTV: there is no problem to use the digital bird repeller for a long time. According to Dr. Zheng Wengang, the sounds are produced by acoustics experts after researching different birds and experimenting many times.

Actual Sound: this is the sounds of hawk.
Actual Sound: this is the sounds made by birds who are scared.

CCTV: these sounds can scare birds. For example, in the cherry garden, pies, crows, sparrow etc. are the frequenters in the garden. The sounds can be timing alternated from hawks sound to scared sounds of birds. The opening and closing of the digital bird repeller can be timing set.

CCTV: although there are so many functions, its internal structure is not complex.
Zheng Wengang: this is a sound chip, which can record the sounds of the enemies of different birds. The sounds can be broadcast through the power amplifier there are clock chip and sound chip.

CCTV: although the digital bird repeller is not big, its sounds are not low. Do the sounds disturb the daily life of farmers?
Zheng Wengang: the sounds can be adjusted according to the coverage. So it will not disturb the daily life of farmers.

CCTV: Fantastic! You can see, in order to improve digital bird repeller, the researcher take it to fruit garden to popularize its application.

(That is the CCTV interview of the first generation digital bird repeller. Now we have developed second generation digital bird repeller, which integrates 16 sounds in the voice chips and the sounds quality are much improved.)
