Acoustic testing apparatus

Abstract

An acoustic testing apparatus includes a box body, a machine frame, a door frame, a door body, a rotary mechanism and linear displacement mechanisms. The box body has a feed-discharge port. The machine frame has a first opening and a second opening opposite to each other, and is disposed on the box body. The first opening communicates with the feed-discharge port. The door frame is disposed on the machine frame. The door body is disposed on the door frame. The rotary mechanism is disposed on the door frame and is connected to the door body to drive the door body to rotate. The linear displacement mechanisms are disposed on the machine frame and are connected to the door frame to drive the door frame to displace between the first opening and the second opening linearly, thus delivering an object to come in and out of the box body.
