Abstract: A network audio testing system and a network audio testing method thereof for testing the performance of a network communication system during communication are disclosed. The system includes a processing system and a sound simulation device. The processing system is for generating a near-end simulation signal and a far-end simulation signal. The sound simulation device is for receiving and making a near-end simulation sound. The near-end simulation sound is received by a microphone of the network communication system to generate a first test signal. The processing system further simultaneously makes the sound simulation device sounding the near-end simulation sound and a speaker sounding a far-end simulation sound to obtain a second test signal. The processing system compares the first and the second test signal to obtain an attenuation degree of the near-end simulation signal and a residual energy of the far-end simulation signal.

Abstract: A head-up display system embedded in a vehicle having at least one tire is provided. The head-up display system includes a tire sensor, a speed detecting module, a host apparatus and a head-up display apparatus. The tire sensor is disposed within the tire for detecting a temperature and a pressure of the tire, and the speed detecting module detects a speed of the vehicle. The host apparatus drives the tire sensor with a wireless low-frequency signal and receives a high-frequency temperature signal and a high-frequency pressure signal transmitted from the tire sensor. Afterwards, according to the received signals, a processing unit of the host apparatus drives the head-up display apparatus to produce a temperature image, a pressure image and a speed image on a windshield by projecting.

Abstract: An eyeglass with multimedia functions of music playing and remote communication is provided, which includes a frame assembly having two temple members, an earphone, a detachable communication and music module, and a temple tip cover. The detachable communication and music module can be attached to or detached from one of the temple members. A jack socket can be disposed on the detachable communication and music module for plugging in the earphone. The temple tip cover has a hanging portion and used for covering on one of the temple members, and the hanging portion is used for hanging the earphone when not use. Therefore, users can attach the detachable communication and music module to the frame assembly, such that the users can receive phone calls or enjoy music when wearing the eyeglass. Or, the users can detach the detachable communication and music module to reduce the weight of the frame assembly.

Abstract: An eyeglass frame assembly is provided, wherein a music generator is disposed on each of two temples of an eyeglass frame, an earphone jack is disposed on the music generator, for the earphone plugs of a mono earphone and a stereophonic earphone to selectively plug in. Through this design, the user can select to use the mono earphone or the stereophonic earphone according to personal demands, so as to talk on a phone call or enjoy the high quality stereo sound effects.
