Abstract

This invention relates to the field of headphone testing, and more particularly to a noise environment impact testing device for headphones. The invention provides a noise environment impact testing device for headphones capable of generating three different noise environments. The device includes a base frame, a mounting plate frame, sound receivers, and a first support plate. The mounting plate frame is connected to the top center of the base frame, and sound receivers are mounted on both sides of the mounting plate frame. The first support plate is connected to the top of the base frame, and the mounting plate frame is located within the first support plate. The invention is activated by a sound generator, which then rotates the output shaft of a servo motor, causing a turntable to rotate. This causes the top block to contact the top rod twice, resulting in the sound generator emitting three different sounds, thus achieving a diversified testing effect.
