碩士 === 崑山科技大學 === 電機工程研究所 === 102 === This paper focuses on the research and design of wireless audio recording & playing interface based on the combination of 2.4GHz wireless communication and USB Dongle. The final purpose is to work out an audio effect transmission application with the function of controlling the audio recording and playing of remote computer, which can be applied in vehicles and digital home entertainment for multimedia control and operations. From the moment when wireless is used, the life of human being has become more convenient and a lot of restrictions arising from the use of wires have disappeared. The advance of science has accelerated the changes of technology. From wireless voice transmission to telegram of Morse Code, till the infrared ray, bluetooth, microwave, wireless network and satellite transmission of today, from voice to text, photo and video, all these have greatly changed the life style of human being, and they are the very benefits coming from wireless transmission. With the popularization of computer and 3C products, they have appeared in every corner of our daily life. At present most 3C products employ USB as interface for external transmission, and the only main differences lie in the shape of products. Therefore, the USB technology will be applied in more and more diversely. This paper, based on the infrastructure of USB Dongle interface, has realized the improvement from wired to wireless communication, providing a short-distance wireless communication interface for future 3C products.
