Description
Technical field
This utility model relates to a kind of being applied to and applies the sound equipment public address in Specialty Hi-Fi to point to being automatically positioned of region
Device.
Background technology
At present, the furred ceiling audio amplifier of specialty is when mounted on the market, in order to improve the precision that public address points to the location in region, main
If using and debugging being manually repeated, whole debugging process not only precision is difficult to control, and extremely loses time.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of installation accuracy and installation effectiveness of improving, and fall
The cost of labor of low engineering construction and the sound equipment public address of time point to the automatic positioning equipment in region.
For achieving the above object, a kind of sound equipment public address that this utility model provides points to the automatic positioning equipment in region, its
In, this device include power amplifier output audio signal module and power amplifier output audio signal block coupled in series loudspeaker load blocks and
The audio frequency power conversion circuit module of loudspeaker load blocks series connection and the MCU of audio frequency power conversion circuit block coupled in series control electricity
Road and Acquisition Circuit in parallel with loudspeaker load blocks two ends respectively and laser powered sensor circuit.Above-mentioned Acquisition Circuit is with height
The state of resistance is connected in parallel on loudspeaker load two ends, to guarantee not affect the tonequality of audio amplifier.The outfan of Acquisition Circuit controls with MCU
Circuit connects；It is provided with between described loudspeaker load blocks and laser powered sensor circuit and controls opening of break-make with MCU control circuit
Close.Described laser powered sensor circuit is connected with generating laser.
The beneficial effects of the utility model are to have raising installation accuracy and installation effectiveness, and reduce the artificial of engineering construction
Cost and the effect of time.Owing to the most hard-wired audio amplifier can specify the location dress that the axial public address of audio amplifier points to
Put, realize fixedly mounting aloft by increasing the measures such as Acquisition Circuit, audio frequency power conversion circuit and laser powered sensor circuit
In the case of audio amplifier, a particular audio signal can be provided to bear to loudspeaker through power amplifier output audio signal module by player of source of sound
Carrying module two ends, then drive built-in generating laser, launch the light beam of laser positioning, light beam quickly and clearly projects
Public address needed for audio amplifier target points to region, thus the public address solving tradition audio amplifier installing engineering points to the difficulty of zone location
Degree, improves the efficiency of installation accuracy and installation, reduces the defect of the cost of labor of engineering construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is frame principle figure of the present utility model；
Fig. 3 is the structural representation that this utility model uses shape.
Detailed description of the invention
Below in conjunction with the accompanying drawings utility model is described in further detail.
As Figure 1-3, a kind of sound equipment public address points to the automatic positioning equipment 3 in region, and this device includes that power amplifier exports sound
Frequently the audio frequency that signaling module is connected with loudspeaker load blocks with the loudspeaker load blocks of power amplifier output audio signal block coupled in series
Power conversion circuit module and the MCU control circuit of audio frequency power conversion circuit block coupled in series and respectively with loudspeaker load blocks
The Acquisition Circuit of two ends parallel connection and laser powered sensor circuit.Above-mentioned Acquisition Circuit is to be connected in parallel on loudspeaker load with the state of high value
Two ends, to guarantee not affect the tonequality of audio amplifier.The outfan of Acquisition Circuit is connected with MCU control circuit；Described loudspeaker load
It is provided with between module and laser powered sensor circuit and the switch of MCU control circuit control break-make.Described laser powered sensor circuit with
Generating laser 2 connects.Thus, as long as Acquisition Circuit recognizes enough big audio frequency (music) signals, audio-frequency electric will be passed through
Power change-over circuit module changes out the stable power that automatic positioning equipment 3 normally works, and is not the most default special audio letter
Number, generating laser 2 does not works, it is ensured that will not send light beam when normal appreciation music and affect audience.Only in sound equipment work
During journey installation, when Acquisition Circuit recognize by player of source of sound provide sufficiently large preset particular audio signal time,
Laser powered sensor circuit will be automatically started, it is provided that launch laser to the electric power of generating laser 2 steady operation by single-chip microcomputer
The light beam of location.Built in sound box generating laser 2 light outlets is to be fixed on the sound of audio amplifier front panel by special fixing device
As geometric center position, which ensure that the accuracy that light beam positions, it is achieved thereby that when audio engineering installation, sound equipment
Public address points to the purpose of the practicality being automatically positioned in region.It addition, above-mentioned automatic positioning equipment 3 is mounted in sound equipment 1,
It is also associated with audio-frequency power amplifier at sound equipment 1.
During construction, the most hard-wired audio amplifier can specify the positioner that the axial public address of audio amplifier points to, and passes through
Increase the measures such as Acquisition Circuit, audio frequency power conversion circuit and laser powered sensor circuit and realize fixedly mounting aloft the feelings of audio amplifier
Under condition, a particular audio signal can be provided to loudspeaker load blocks two through power amplifier output audio signal module by player of source of sound
End, then drives built-in generating laser 2, launches the light beam of laser positioning, and light beam quickly and is clearly incident upon audio amplifier mesh
Public address needed for mark points to region, thus the public address solving tradition audio amplifier installing engineering points to the difficulty of zone location.
