| Summary: | 碩士 === 崑山科技大學 === 電機工程研究所 === 103 === This device realizes 2.4GHz-based wireless sound recording, music playing, and humanization interface control platform. Main creative features including users can carry out sound recording, music playing, keyboard, mouse, and entertainment key five-in-one control on a remote computer through wireless transmission, and the wireless transmission distance between a user and a computer can be longer than 30M. The advantage is that the computer is not limited by connecting line. In actual operation, the device not only demonstrate instant response, but also has no delay or distortion phenomenon at the time of sound recording and music playing, in addition, the actions of keyboard and mouse can also demonstrate instant response.
The main research & development and design of device are digital-family-entertainment-based PC Wireless USB Audio/HID prototype platform. Only one USB Dongle is used between the prototype platform and a computer to realize the function of transmitting five kinds of data; the self-developed USB Dongle has 2.4GHz data transmission capacity. The platform uses low cost 2.4G wireless transmission ICas a transmission solution of wireless Audio/HID. It has the advantages of low cost and low power consumption. Therefore, it is suitable for developing toward commercialization. The device can combine the request data of human-computer interface operation, the request data of sound playing, and request data of sound recording into a single wireless package to be used as a device with wireless isochronous transmission function. In the respect of device design, it can be divided into two parts of USB Dongle end and wireless music keyboard end. The wireless 2.4GHz transmission is realized between the two parts to communicate USB HID/Audio orders and data.
The scenario of wireless music keyboard transmission technology developed by this device is a scenario application implementation example of digital family entertainment, in which wireless USB Dongle connects to the USB interface of a living room computer so that a user who sits sofa in living room can remote-control the PC through wireless music keyboard operation, transmitting HID actions to the computer, receiving music from remote PC, and recording sound back to remote PC, so as to realize remote wireless PC control with the advantage that sound recording playing is not limited by line.
