Abstract: A graphical ultrasonic module and driver assistance system are provided. The graphical ultrasonic module includes an ultrasonic sensor array and an ultrasonic transmitter array. The ultrasonic sensor array includes three or more ultrasonic sensors, and the ultrasonic sensors form a virtual plane. The ultrasonic transmitter array includes a plurality of ultrasonic transmitters. The geometric center of the ultrasonic transmitter array is substantially the same as the geometric center of the ultrasonic sensor array.

Abstract: An electronic glasses includes a lens frame, a first temple, a second temple, an electronic device and an audio I/O device. The Hall sensor is disposed at one of the lens frame, the first template, and the second temple. The audio I/O device is disposed at another of the lens frame, the first temple and the second temple, and provided with a magnetic element. The Hall sensor provides a first signal for the electronic device when the first temple and/or the second temple are folded to make the Hall sensor and the audio I/O device close to each other, and the Hall sensor provides a second signal for the electronic device when the first temple or the second temple are unfolded to make the Hall sensor and the audio I/O device be away from each other.

Abstract: A thin speaker with a voice coil having a damper function, includes a frame, a magnetic device, a damper voice coil and a diaphragm. The damper voice coil comprises a holding member and a conductive member. The holding member includes a holding base and two holding suspension portions formed on two ends of the holding base. The conductive member includes a conductor wound to form a first winding at one side of the holding base and a second winding at the other side of the holding base, and two conductive suspension portions formed on two ends of the conductor and located on the top of holding suspension portions. Since the damper voice coil has the functions of a damper and a voice coil, the present invention is capable of maintaining a thin design and ensuring the up and down movements of the holding base to prevent its deflection.
