摘要： A microphone connector assembly comprises a receptacle and a sleeve. The receptacle includes a housing, a first cavity formed within the housing, a frame, a protrusion formed on the frame, and a first electrical block supported by the frame and positioned within the first cavity. The sleeve includes an outer shell, a second cavity formed within the outer shell, a keyway, and a second electrical block positioned within the second cavity. The sleeve is insertable into the receptacle such that the protrusion enters the keyway and the first and second electrical blocks engage one another.

摘要： A microphone can include a cover having a series of slits and a nest. The nest can be configured to receive a first diaphragm, a second diaphragm, and a PCB in a stacked arrangement, such that the PCB is positioned between the first diaphragm and the second diaphragm. Also the first diaphragm can define a first plane, the second diaphragm can define a second plane, and the PCB can define a third plane and the first plane, the second plane, and the third plane can extend parallel to one another. The cover can also include slits having a first length and a second length, and the first length can be greater than the second length. The slits can extend both radially and axially.

摘要： Adaptive self-tunable antenna systems and methods are provided including a closed-loop system for sensing near-field RF signals of transmitted RF signals and tuning an antenna or switching between multiple antennas, so that the strength of the transmitted RF signals is maximized. A sensing antenna detects the near-field RF signal, which is filtered and converted to an RF strength control signal that can be used to generate an antenna tuning control signal. An antenna tuner uses the antenna tuning control signal to keep the antenna in resonance by dynamically changing the electrical length of the antenna or switching between multiple antennas to maximize the strength of the radiated RF signal. Such antennas may be less prone to detuning due to interaction with human bodies or other objects. Dynamically matching the antennas to an RF power amplifier and low noise amplifier can improve stability, power efficiency, gain, noise figure, and receiver sensitivity.

摘要： A portable audio networking system is provided that includes master devices and slave devices in communication over cables adapted to simultaneously transport a digital audio signal, DC power, and a data signal. Master devices are configured to receive a digital audio signal, distribute power, and transceive a data signal, and slave devices are configured to transmit the digital audio signal to master devices, receive the power from master devices, and transceive the data signal with master devices. Slave devices can include wireless audio receivers that receive an RF signal containing an audio signal from wireless audio transmitters. Master devices can include gateway interconnection devices that act as hubs and routers for the system. The reduction in the number of cables compared to traditional systems results in less weight for crew members to carry and easier setup of the system. Remote control of wireless audio transmitters is also enabled.

摘要： A wireless audio receiver system and method is provided that is capable of receiving one or more radio frequency (RF) signals containing audio signals modulated by analog and/or digital modulation schemes, operating in full diversity mode or switched diversity mode, demodulating the RF signals, and outputting analog audio signals and a combined digital audio signal. The system and method switches multiple diversity antennas to route received RF signals to respective RF signal processing paths. Digitized passband modulated signals are demodulated to generate analog audio signals, and a combined digital audio signal with one or multiple channels may also be generated. The system and method are capable of demodulating signals modulated using a wide variety of modulation schemes. Reconfigurable computing components are utilized to demodulate digitized passband modulated signals and generate the analog audio signals and combined digital audio signal.
