Abstract: An antenna integration is applicable for a wireless microphone, a wireless teaching system, and a wireless tour guide system of ultra-high frequencies. The antenna integration contains an antenna integrator including: multiple antenna input ends, a power control module, multiple radio frequency (RF) attenuations, and multiple radio frequency (RF) input ons/offs. The multiple antenna input ends are arranged in the antenna integrator and are configured to input radio frequency (RF) signals of multiple pairs of antennas. The power control module is arranged in the antenna integrator and is configured to turn on/off a power supply to the multiple pairs of antennas. The multiple radio frequency (RF) attenuations are arranged in the antenna integrator and are configured to control an input of the RF signals. The multiple radio frequency (RF) input ons/offs are arranged in the antenna integrator and are configured to turn on/off the RF signals.

Abstract: A user interface of a wireless audio transmission system is applicable for any one of wireless monitoring, a wireless microphone, a wireless speaker system, a wireless conference system, a wireless teaching system, and a wireless tour guide system. The wireless audio transmission system contains: a channel menu interface, a channel management module, and an application program module. The channel menu interface is configured to transmit multiple sets of frequencies. The channel management module is coupled with the channel menu interface and includes a channel menu. The application program module is coupled with the channel management module and includes a menu data storage module configured to save the multiple sets of frequencies in the menu data storage module from the channel menu interface, and the multiple sets of frequencies being established as the channel menu by ways of the channel management module.

Abstract: A battery-powered wireless transmitter for connecting to a musical instrument comprising an antenna; a cover comprising a well at one end and a first gear on one side of the well; a T-shaped plug having a horizontal section pivotably disposed in the well and a vertical section projecting out of the well, the plug comprising a spring member at one end of the horizontal section, a second gear on the other end of the horizontal section being urged by the spring member to mesh with the first gear, and an electrically conductive rod projecting out of the vertical section; and an adapter comprising an end socket. Pivoting the rod about the horizontal section by rotating the second gear about the fixed first gear will adjust an angle of the plug with respect to the cover and fix the angle after stopping the pivoting.
