a building shaker, a vibration motor, is a machine. Earthquake artifact still uses noise to control noise.

the building vibration equipment will cause slight vibration on the roof, and cooperate with special sound waves to reduce the noise upstairs. The vibration device can stop the noise from being made upstairs by playing a warning sound or a counterattack sound.

the acoustic building vibration device is a sound box device to solve the problem of building noise between residents. By touching the floor or wall, the device penetrates the music in the player through the floor and wall, and transmits the music to the upstairs or the opposite wall without attenuation.

Extended information

The purchase of the artifact of the earthquake absorber has also promoted the hot sale of "soundproof earplugs". This earplug is for the buyer's own use, because although the "artifact" is said to be placed on a stool, it can reduce the noise pollution at home.

some of the "artifacts" with different prices need to be installed on the roof, and some don't need to be punched. You can choose the mobile phone control package to remotely control the "artifacts". In the new model of 217, the soundproof cotton is enlarged and thickened, which will have less impact on the family.

The "artifact" of the building shaker, which does not need to be installed with holes, supports the main engine on the roof through a telescopic rod. There is a small machine in the main engine, which weighs * * * 1kg and has a power of 1w to 1w. When you shake the main engine, you can hear the clanging noise, which is the sound from the hammer inside. When working, the motor in the main engine will make the hammer do piston movement. The vibration amplitude and sound of the hammer are different with different gears.
