Description

A kind of Multifunctional wireless microphone main frame
Technical field
The utility model is related to a kind of Multifunctional wireless microphone main frame, and it is applied to school instruction, corporate lecture, training And amusement etc. occasion.
Background technology
The occasion such as teaching, company's meeting, speech, visit explanation commonly uses microphone system at the scene, and it includes pickup portion Divide and part of raising one's voice, miaow head capture speech can be led to and the broadcasting that amplified after processing amplification.
Exemplified by visiting and explain, microphone system is one need to carry on the back the box body with hanging over guide, and box body is provided with Loudspeaker horn, is amplified, this backs on the body equivalent to by audio amplifier by being connected with miaow head with obtaining sound, is very to make people tired;And be Reduction volume and weight, again limit the quality of broadcasting of loudspeaker horn.In fact, audio amplifier can independently be set in each commentary point Put, only need to arrange small-sized pickup main frame with guide, pickup main frame and audio amplifier wireless connection, just may be used when row is to commentary point Broadcast.And for example in family entertainment place(Karaoke), also need to play music VF while being amplified, if do not had Reverberation effect regulatory function, is just difficult to avoid that audio self-excitation and the generation of the stiff situation of sound.In addition, using wireless microphone Also need to consider section frequency problem during system, conventional 300-900MHz frequency ranges, 2.4GHz frequency ranges are by many electronic apparatus applications, wirelessly Microphone system easily influences transmission quality under frequency range conflict interference, causes broadcast effect to decline, or even sharp noise.With On be problem urgently to be resolved hurrily in the prior art.
Utility model content
To overcome the defect of the prior art referred in background technology, the utility model proposes a kind of multifunction wireless Mike Wind main frame, meets the use demand of the occasions such as school instruction, corporate lecture, training and amusement, and its particular technique content is as follows:
A kind of Multifunctional wireless microphone main frame, has:MCU master controls and audio decoder IC, pickup miaow head, connection pickup miaow The amplifier of microphone of head, reverberation processor, display screen, connect the driver module of display screen, 5.8G wireless modules one with And power module, it obtains audio by pickup miaow head, sent after being adjusted through reverberation effect to audio amplifier, the MCU master controls and audio Decoding IC is connected with some function buttons for operational control, and the Multifunctional wireless microphone main frame is supplied by built-in lithium battery Electricity.
Among one or more embodiments of the present utility model, the microphone main frame, which has, is used for what audio input was played Audio interface block, the Audio interface block includes AUX sources of sound interface or/and TF decks, supports the external computers of AUX or mobile phone sound Frequency is played and TF cards local audio is played, while also supporting to deposit sound recording to TF cards.
Among one or more embodiments of the present utility model, the microphone main frame, which has, to be used to support laser pointer to grasp The laser tube of work.
Among one or more embodiments of the present utility model, the power module, which includes power management IC, charge/discharge, to be protected Protect module and MINI-USB charging inlets.
The beneficial effects of the utility model are:Microphone is integrated with, the digital audio of TF cards/AUX carriers is played, recording, Reverberation, the function such as laser pointer, can be realized and the one-to-one, one-to-many of wireless sound box, multi-to-multi by 5.8G wireless modules Matching set, meet school instruction, corporate lecture, training and entertain etc. occasion use demand;And avoid other conventional Numerous interference of frequency range, it is ensured that transmission quality and transmission range.Simultaneously as pickup part and part of raising one's voice are discrete, pick up Line point(Microphone main frame)It can be made very small ingeniously, just can be realized and continued a journey for a long time with lithium battery.As can be seen here, this practicality is new Type is a technical, practicality and economy outstanding product, is adapted to promote the use of.
Brief description of the drawings
Fig. 1 is the implementation framework schematic diagram of Multifunctional wireless microphone main frame of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1, application scheme is further described:
