The output device can be an audio interface, a bluetooth transmission device, or both an audio interface and a bluetooth transmission device. Therefore, the external earphone can be inserted into the hearing testing device through the audio interface, or be connected with the hearing testing device through Bluetooth. The external earphone receives the earphone driving signal, and generates vibration with the target vibration frequency and intensity to drive the middle ear, so as to perform qualitative and quantitative detection and analysis on the air conduction hearing of the human body. In this embodiment, due to the detection process of bone conduction hearing, the vibration directly drives the inner ear through the skull without passing through the middle ear.
