Description

Technical Field

[0001] This application relates to the technical field of pet barking prevention, and particularly to an environmental audio filtering system and a barking stopper. Background Art

[0002] With the improvement of people's living standards, people's attention to the quality of life of pets has also been continuously improved, and more and more people regard pets as members of the family. However, pet dogs sometimes can't help their natural instincts, and their barks often interfere with people's normal life, and at the same time, the owner is also in the potential crisis of being complained by neighbors. So people invented a product that can make pet dogs stop unnecessary or excessive barking - a barking stopper.

[0003] Barking stoppers mainly include sound barking stoppers, vibration barking stoppers, electric shock barking stoppers, and hybrid barking stoppers.

[0004] Among them, the sound barking stopper stimulates pets by emitting high-frequency, low-frequency or specific-frequency sounds to make them stop barking. These sounds are usually designed to be uncomfortable or unpleasant to attract the attention of pets and change their behavior.

[0005] Currently, the structure of almost all types of barking stoppers on the market that trigger the barking prevention function is a microphone, abbreviated as a microphone head. No matter the quality of the microphone head, it always fails to properly complete the function of preventing false triggering by environmental noise. If the circuit hardware and software are upgraded to solve the problem of false triggering, it will bring a multiple increase in cost and cannot be smoothly implemented. Utility Model Content

Therefore, the drawings and the description are to be regarded as illustrative in nature and not restrictive.

[0043] A sound collector 4, the sound collector 4 is disposed on one side of the installation base 1 having the sound inlet 111. The sound collector 4 has a sound collecting channel 41, and the sound collecting channel 41 runs through opposite ends of the sound collector 4. The sound inlet end of the sound collecting channel 41 is used to connect to the sound - producing part of an animal, and the sound outlet end of the sound collecting channel 41 is located on a side close to the sound inlet 111. The sound outlet end of the sound collecting channel 41 is arranged around the diaphragm 3. The sound collecting channel 41 is used to aggregate sound waves, and the sound collector 4 is used to shield environmental noise.

[0044] Wherein, the above - mentioned animal can be a pet or other animals other than pets.

[0045] The environmental audio filtering system of the present utility model includes an installation base 1, a microphone 2, a diaphragm 3, and a microphone 4. When in use, the microphone 4 is attached to the sound - emitting part of an animal. On the one hand, the microphone 4 can aggregate sound waves, and on the other hand, it can shield environmental noise. The sound waves aggregated by the microphone 4 are strengthened and amplified, causing the diaphragm 3 to vibrate. The vibration picked up by the diaphragm 3 is protected by the sound cavity 112 to prevent sound wave loss. The sound waves output by the diaphragm 3 are converted into electronic analog signals through the microphone 2, thereby emitting sound to stop the barking of the pet. Among them, because the microphone 4 can physically shield environmental noise directionally, and because the sound waves are amplified multiple times through the microphone 4 and the diaphragm 3, the sensitivity of the microphone 2 can be set lower than the conventional standard. The directional physical shielding of the microphone 4 and the low - sensitivity setting of the microphone 2 are combined, and the two cooperate synergistically to effectively shield the environmental noise from the surrounding. This enables the environmental audio filtering system to still serve the only object sensitively in a complex working environment, and can effectively prevent false triggering caused by interference from other surrounding environmental sounds.
