Abstract: An electronic device and its stylus pen having an FM antenna functionality are provided. The stylus pen includes a pen tip, a penholder, and a metal element spirally surrounding the penholder from a first end portion to a second end portion of the penholder. The pen tip is made of conductive material, the penholder is made of insulated material, and at least one end portion of the metal element is electrically coupled to the pen tip. When the pen tip is inserted into an antenna jack defined in the electronic device, the metal element of the stylus pen is electrically coupled via the pen tip to a radio receiving circuit arranged inside the electronic device. The metal element is thereby enabled to act as an FM antenna and is enabled to receive wireless signals from the radio receiving circuit and transmit wireless signals to the radio receiving circuit.

Abstract: A road condition management method includes: obtaining geographical location information sent by at least one roadblock device, wherein each geographical location information comprises a geographical location of the corresponding roadblock device; storing the obtained geographical location information to a storage device; and generating a corresponding road condition prompting information related to an target area according to the geographical location information stored in the storage device in response to a search request for searching a road condition of the target area sent by a terminal device.

Abstract: The disclosed subject matter provides a communications device, a volume adjusting system and method. The communications device includes a loudspeaker, a microphone, and a communication unit. The communications device communicates with other communications devices via the communication unit. The communications device detects a first sound intensity of sound signals collected by the microphone, and detects a second sound intensity of sound signals received by the communication unit from the other communications devices. The communications device further adjusts the sound signals received by the communication unit according to a comparison result of the first sound intensity and the second sound intensity, and outputs the adjusted sound signals via the loudspeaker.
