1. A detection apparatus comprising:

  • a housing;

    a circuit board received in the housing;

    an image detection module received in the housing, and the image detection module comprising;

    a barrel;

    at least one lens received in the barrel; and

    an image sensor configured to receive light from the at least one lens and generate a plurality of image signals;

    an ultrasonic detection module comprising;

    a piezoelectric member fixed to the housing to emit a plurality of ultrasonic waves and receive the reflected ultrasonic waves; and

    an ultrasonic control module operable to apply a voltage on the piezoelectric member, receive the voltages generated by the piezoelectric member, and generate a plurality of voltage signals when receiving the voltages from the piezoelectric member; and

    a connecting terminal electrically connected to the circuit board to output the image signals and the voltage signals, wherein the image sensor is electrically connected to the circuit board, and the ultrasonic control module is electrically connected to the piezoelectric member and the circuit board.
