Abstract
The utility model discloses a wireless microphone transceiving device, which comprises a transmitting module and a radio-frequency receiving module. The input end of a microphone is connected with the transmitting module through an acoustic-electric converter; the device comprises a DVD decoding circuit and a DVD player core; the DVD player core is connected with the DVD decoding circuit; the radio-frequency receiving module is connected with the DVD decoding circuit through an interface conversion circuit; and the DVD decoding circuit is connected with an audio output port and a video output port. The device can further processes the received microphone signals and outputs image or video signals at the same time, thereby greatly expanding the function of the wireless microphone transceiving device.
Description
Technical field
The utility model relates to a kind of wireless transmitter, especially relates to a kind of microphone R-T unit.
Background technology
In places such as large-scale stage, concert, recording, gymnasium, news conference issue, stage monitoring and momentous conference scenes, after traditional microphone is input to power amplifier or sound console by audio transmission line, play back by public address equipments such as audio amplifiers again, dilatory for fear of audio transmission line adopts the R-T unit of wireless microphone (microphone).Existing wireless microphone R-T unit only plays the function that transmits with received signal, also can't further process audio signal, and it does not handle the function of image or vision signal yet simultaneously, can't satisfy client's multi-functional demand.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of multi-functional wireless microphone R-T unit.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of wireless microphone R-T unit, comprise transmitter module and Receiver Module, the microphone input is connected with described transmitter module by acoustical-electrical transducer, comprise DVD decoding circuit and DVD player core, described DVD player core is connected with described DVD decoding circuit, described Receiver Module is connected with described DVD decoding circuit by interface conversion circuit, and described DVD decoding circuit is connected with audio output port and video-out port.
Described audio output port comprises 5.1 sound channel output interfaces and left and right acoustic channels output interface.
Described video-out port comprises optical fiber output interface and coaxial output interface.
Described DVD decoding circuit comprises chip and the peripheral cell that a model is AL8203.
Power circuit is connected with described interface conversion circuit.
Compared with prior art, the utility model has the advantages that and can the microphone signal that receive be further processed, simultaneously can also output image or vision signal, expanded the function of wireless microphone R-T unit widely.
