Abstract
A detection apparatus includes a housing, a circuit board, an image detection module, an ultrasonic detection module, and a connecting terminal. The image detection module includes a barrel, one or more lenses received in the barrel, and an image sensor configured to receive light through the lens and generate image signals. The image sensor is electrically connected to the circuit board. The ultrasonic detection module includes a piezoelectric member fixed to the housing to emit ultrasonic waves and receive reflected ultrasonic waves, and an ultrasonic control module operable to apply a voltage on the piezoelectric member, receive alternating voltages generated by the piezoelectric member, and generate voltage signals when receiving the voltages from the piezoelectric member. The ultrasonic control module is electrically connected to the piezoelectric member and the circuit board. The connecting terminal is electrically connected to the circuit board to output the image signals and the voltage signals.
