Abstract

An ultrasonic mouse comprises an ultrasonic module, a processing unit and a transmission interface. The ultrasonic module comprises ultrasonic transmitting elements and a plurality of ultrasonic receiving elements, the ultrasonic receiving elements and the ultrasonic transmitting elements are arranged in a matrix, and the ultrasonic receiving elements are arranged around the ultrasonic transmitting elements. The ultrasonic transmitting element generates an ultrasonic signal, and when the ultrasonic mouse moves and at least one of the ultrasonic receiving elements receives the ultrasonic signal, sensing information is generated. The processing unit is electrically connected with the ultrasonic module, receives the sensing information and calculates and generates a moving signal. The transmission interface is electrically connected with the processing unit and transmits the mobile signal.
