Description

A kind of Multi-phone microphone

Technical field

The utility model relates to wireless microphone, particularly a kind of Multi-phone microphone with remote control and headphone monitor function.

Background technology

Traditional common microphone is just simply amplified processing to sound, and its shortcoming is:

(1) traditional common microphone can not be controlled the various audio effects such as reverberation, high low pitch joint; (2) traditional common microphone function is few, the needs of the amusement that cannot be adapted to play Karaoka; (3) traditional wireless microphone is not with foldback monitor function, need to purchase the equipment such as power amplifier, audio amplifier, and not only equipment purchasing cost is high, and easily occurs uttering long and high-pitched sounds while amplifying, and can not realize wireless monitor.Therefore, traditional wireless microphone can not meet the requirement of family expenses Karaoke amusement and the amusement of network K song.

Utility model content

For overcoming the shortcomings and deficiencies of above-mentioned prior art, the utility model provides a kind of Multi-phone microphone with remote control and headphone monitor function.

According to the above-mentioned problem that needs solution, the technical scheme that this Multifunctional wireless microphone is taked is:

A Multi-phone microphone, comprises voice unit, and described voice unit comprises voice pickup model, signal reception and analysis and processing module, central processing module, DA modular converter and the signal amplification module connecting successively; Described central processing module comprises MCU and connectedly a plurality ofly respectively voice signal is processed, made microphone possess the acoustic processing chip of reverberation adjusting, sound effect regulatory function by different mode.

Preferably, described signal amplification module is connected with wireless transmitter module, and Multi-phone microphone also disposes the wireless monitor earphone that receives the audio signal that wireless transmitter module sends.

Further preferred, also comprise the remote-controlled launch unit of controlling broadcast source equipment, described remote-controlled launch unit comprises remote keying, key analysis module, key processing module and the infrared sending module connecting successively.

Concrete, described voice unit also comprises infrared reception, the decoder module being connected with central processing module.

Necessary, also comprise the display screen being connected with central processing module.

Compared with prior art, the beneficial effects of the utility model have:

(1) Multi-phone microphone described in the utility model, comprise that a plurality of professional sound process chip only need use the peripheral element of a little, just can reach high efficiency tonequality processing capacity, by button, regulate, according to the ultra-red order receiving, can comprise total volume, microphone volume, volume of music, the reverberation degree of depth, sound delay, high pitch volume, bass volume, music is dodged, the dry sound of microphone, quiet, audio is default, the setting of many standalone features such as User Defined, also have common, rock and roll, popular, classic, jazz, the multiple music balancer function such as dance music, set several functions, thereby greatly improved the scope of application of microphone,

(2) Multi-phone microphone described in the utility model, signal reception and analysis and processing module are by processing microphone signal and accompaniment music signal, pass through again wireless transmission, utilize wireless monitor earphone to realize wireless monitor function, substitute traditional family expenses karaoke equipment, can reduce equipment cost, while avoiding using audio amplifier too loudly, affect the problem of surrounding resident.

Embodiment

For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, the utility model is explained in further detail.

New the disclosed Multi-phone microphone of the utility model, comprises voice unit and the remote-controlled launch unit of controlling broadcast source equipment.As shown in Figure 1, described voice unit comprises the voice pickup model connecting successively, signal receives and analysis and processing module, central processing module, DA modular converter, signal amplification module and wireless transmitter module, described voice pickup model adopts moving coil microphone, described wireless transmitter module sends to outside power amplifying device or wireless monitor earphone by voice signal, described voice unit also comprises that the infrared signal being connected with central processing module receives, decoder module, described central processing module comprises MCU and a plurality of acoustic processing chip of respectively voice signal being processed by different mode.As shown in Figure 2, described remote-controlled launch unit comprises remote keying, key analysis module, key processing module and the infrared sending module connecting successively.

During specific works, moving coil microphone receives the transmitting voice signal picking up to signal and analysis and processing module, the signal that signal receives and analysis and processing module is picked up microphone and amplifying and effective noise reduction process, except voice signal, signal receive and analysis and processing module also to the external equipment audio signal receiving, for example accompaniment music is analyzed, the problem that solves echo and utter long and high-pitched sounds improves definition and the validity of voice signal greatly, signal receive and analysis and processing module by the good voice signal of analyzing and processing and external equipment audio signal transmission to central processing module, central processing module comprises MCU and a plurality of acoustic processing chip of respectively voice signal being processed by different mode, according to infrared signal, receive, the ultra-red order that decoder module receives, central processing module selects different acoustic processing chips to carry out analyzing and processing to voice signal and external equipment audio signal, showing the current various audio situation numerical value of screen display simultaneously, then the good voice signal of analyzing and processing is carried out to D/A conversion, power amplification, finally signal is transferred to outside power amplifying device or wireless headset audiomonitor by wireless transmitter module.

Fig. 3 is this Multi-phone microphone remote controller schematic diagram, microphone case is rectangular-shaped, by button, regulate, central processing module can comprise the setting of many standalone features such as total volume, microphone volume, volume of music, the reverberation degree of depth, sound delay, high pitch volume, bass volume, music are dodged, the dry sound of microphone, quiet, audio default, User Defined according to the ultra-red order receiving, also have the multiple music balancer functions such as common, rock and roll, popular, classic, jazz, dance music, set several functions.
