Description
Technical field
The utility model relates to digital audio equipment field, particularly a kind of wireless digitizing professional sound system.
Background technology
At present, in similar convention, concert, in the site of activity such as propaganda activity, in order to reach the object regulating sound equipment result of broadcast, generally sound console can be used, but, present sound console with audio amplifier, in the placement process of power amplifier, a large amount of transmission lines can be used, for the transmission of signal, this makes the setting up procedure of sound console very complicated and loaded down with trivial details, and wiring is vulnerable to the restriction in place, transmission range has a definite limitation, due to above-mentioned reason, so nowadays the time of the stereo set of site of activity general all longer, and, the operation of often kind of sound console is all comparatively complicated, very professional personnel are wanted to operate, in addition, for performing arts agency or sound equipment leasing company, in order to meet the demand not playing meeting specification together, just need the sound console purchasing various model, this can increase the cost of operation virtually.
Utility model content
The purpose of this utility model is to solve the problem and deficiency, a kind of wireless digitizing professional sound system is provided, this wireless digitizing professional sound system without the need to wiring, has convenient quick, the transmission of arrangement convenience, simple to operate, directly perceived, application build apart from being no longer subject to the advantages such as the restriction of cable, cost are relatively low in installation process.
The technical solution of the utility model is achieved in that
A kind of wireless digitizing professional sound system, its feature is to comprise wireless sender unit, sound source, several DSP processors, several audio amplifiers, the quantity of wherein said DSP processor is identical with the quantity of audio amplifier, described sound source plays movement by casing and the CD be installed on casing, SD card draw-in groove, USB interface, circuit main board is formed, described wireless sender unit is wireless microphone signals transmitting-receiving instrument, and this wireless sender unit is connected with DSP processor, wireless microphone signals is transferred on DSP processor, described DSP processor is by housing and the touch screen that is installed on housing, circuit board module, radio receiving transmitting module is formed, described audio amplifier is by casing, wireless receiving module, power amplification circuit module, speaker unit is formed, described audio amplifier carries out wireless signal by its wireless receiving module with the radio receiving transmitting module of DSP processor and is connected.
The beneficial effects of the utility model: wireless digitizing professional sound system described in the utility model comprises wireless sender unit, sound source and several DSP processors, several audio amplifiers, described DSP processor is by the touch screen on housing and installation and housing, circuit board module radio receiving transmitting module is formed, described DSP processor can receive the signal that wireless sender unit and sound source send, audio signal after process can transfer out with the form of wireless signal again by DSP processor simultaneously, then received by audio amplifier and play out music, without the need to wiring in this system, installation arranges more convenient, and meeting-place environmental limit can not be subject to, transmission is apart from the restriction no longer by cable, and the DSP processor of touch screen formula, its operation can be made more directly perceived, simple.Meanwhile, this system can increase or reduce the quantity of DSP processor and audio amplifier as required, the sound system of different performance of arranging in pairs or groups out, for enterprise, required for the equipment purchased will reduce, thus greatly can reduce the cost of enterprise.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present utility model.
Embodiment
As shown in Figure 1, the wireless digitizing professional sound system of one described in the utility model, comprise wireless sender unit 1, sound source 2, several DSP processors 3, several audio amplifiers 4, the quantity of wherein said DSP processor 3 is identical with the quantity of audio amplifier 4, described sound source 2 plays movement by casing and the CD be installed on casing, SD card draw-in groove, USB interface, circuit main board is formed, described wireless sender unit 1 is wireless microphone 5 signal transmitting and receiving instrument, and this wireless sender unit 1 is connected with DSP processor 3, with by wireless microphone 5 Signal transmissions on DSP processor 3.Described DSP processor 3 is made up of the touch screen 31 on housing and installation and housing, circuit board module, radio receiving transmitting module, described touch screen 31 is generally equipped with the control software design of special exploitation, touch screen 31 can be used to the function realizing similar traditional sound console regulating button, and, touch screen 31 can also show current sound equipment result of broadcast by the mode of word or figure, the operation needing sense of hearing is made to become observation touch screen 31, thus make operator tell current sound equipment result of broadcast more intuitively, reach the object reducing operation easier.Described audio amplifier 4 is made up of casing, wireless receiving module, power amplification circuit module, speaker unit, described audio amplifier 4 carries out wireless signal by its wireless receiving module with the radio receiving transmitting module of DSP processor 3 and is connected, after the signal that wireless receiving module sends at the radio receiving transmitting module receiving DSP processor 3, pass to power amplification circuit module more just to amplify, finally played out by speaker unit.
Employ wireless transmission between the DSP processor in this sound system and audio amplifier, eliminate loaded down with trivial details wiring process, arrange that the time of sound system can be shorter like this, and can not be subject to the restriction in place, transmission range is no longer subject to the restriction of cable simultaneously.And be realize different acoustics, only need select out appropriate DSP processor 3 as required, and then the audio amplifier 4 of equal number of arranging in pairs or groups out, the configuration in sound system can be made like this to realize standardization, only need buy DSP processor 3 and the audio amplifier 4 of suitable quantity, just can arrange in pairs or groups out multiple acoustics, the sound console of multiple regulation, power amplifier or audio amplifier etc. just need not be bought by such performing arts agency or sound equipment leasing company, thus reduce the operation cost of enterprise.
