Abstract
The utility model discloses a sound cover is gathered to intelligence, including transparent inferior gram force cover and sound collection equipment, the top central point of transparent inferior gram force cover puts and installs three -colour LED lamp, just the inside of transparent inferior gram force cover is provided with the speaker, install the high -frequency vibration membrane in the speaker, and infrared inductor is still installed to the bottom of speaker, the output of sound collection equipment is connected with the input of modulator electricity, the output and the input of power amplification module of modulator are connected, the output and the speaker input electricity of power amplification module are connected. The beneficial effects of the utility model are that: it is effectual to gather the sound, automatically, opening and closing, intelligence, the energy -conserving sound that reduces pollute, it is more attractive.
Description
Technical field
This utility model relates to audio-visual devices technical field, is specially a kind of intelligent poly-sound cover.
Background technology
The a large amount of presentation device in current various showground all can't do without voice introduction, and museum's audible device is many and density big, and sound interferes seriously, and sound pollution is big.Have a strong impact on bandwagon effect.Existing poly-sound cover technology is all to use top lucite hemisphere, and middle installation loudspeaker, upward, the sound that loudspeaker send reflexes to reach inside patron's ear the effect of " poly-sound " to horn mouth by transparent organic glass hemisphere inwall.
Utility model content
The purpose of this utility model is to provide a kind of intelligent poly-sound cover, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of intelligent poly-sound cover, equipment is collected and recorded including transparent acrylic cover and sound, the top center of described transparent acrylic cover is provided with three-color LED light, and described transparent acrylic cover be internally provided with speaker, high frequency diaphragm is installed in described speaker, and the bottom of speaker is also equipped with infrared inductor.
The input of outfan and manipulator that described sound collects and records equipment electrically connects, and the outfan of described manipulator is connected with the input of power amplifier module, and the outfan of described power amplifier module electrically connects with loudspeaker input terminal.
Preferably, described high frequency diaphragm is specially PVDF conducting film.
Preferably, described transparent acrylic cover by hanger erection on wall.
Preferably, described transparent acrylic cover is hemispherical dome structure.
Compared with prior art, the beneficial effects of the utility model are:
1, poly-sound is effective: have employed complete different poly-sound principle, and prior art uses bounce technique, realizes " poly-sound " by a transparent organic glass cover；The principle that this technology has the strongest directivity according to ultrasound wave is made, and is launched by sound together with ultrasound wave, simultaneously because human ear can't hear ultrasound wave, reaches the process of automatic fitration.
2, opening and closing automatically, minimizing sound intelligent, energy-conservation pollutes: someone automatically controls the opening and closing of sound to have infrared inductor can determine whether bottom poly-sound cover.
3, more attractive: owing to poly-sound shroud rim has light-illuminating to form a ring of light, if if coordinating sound ring of light shadow existing, reaching interactive effect, making showpiece more attractive, bandwagon effect is more preferable.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is utility model works schematic flow sheet.
In figure: 1 transparent acrylic cover, 2 suspension rods, 3 three-color LED lights, 4 speakers, 5 high frequency diaphragm, 6 infrared inductors, 7 sound collect and record equipment, 8 manipulators, 9 power amplifier modules.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，A kind of technical scheme of this utility model offer: a kind of intelligent poly-sound cover，Equipment 7 is collected and recorded including transparent acrylic cover 1 and sound，Transparent acrylic cover 1 is hemispherical dome structure，Being arranged on wall by suspension rod 2 of transparent acrylic cover 1，The top center of transparent acrylic cover 1 is provided with three-color LED light 3，Three-color LED light 3 is luminous to surrounding，Light is delivered to the edge of transparent acrylic cover 1，Allow spectators can see the ring of light of poly-sound cover from far away，When phonetic explaining, the ring of light flashes，Play the purpose attracting spectators，And transparent acrylic cover 1 be internally provided with speaker 4，High frequency diaphragm 5 is installed in speaker 4，High frequency diaphragm 5 is specially PVDF conducting film，The operating frequency height of PVDF conducting film can reach more than 60KHz，PVDF conducting film is as the vibration machine part of ultrasound wave and audio signal，PVDF conducting film can occur the ultrasonic signal of 45KHz superimposed with system sounds，Power amplifier module is delivered to after signal is modulated，PVDF conducting film is given again by the signal of amplification，Audio signal and ultrasonic signal are converted to mechanical vibration and with driving air vibration by PVDF conducting film，Owing to the directivity of ultrasound wave is the strongest，Will not scatter to surrounding，So PVDF conducting film direction of vibration we can hear sound，Reach the function of poly-sound，And the bottom of speaker 4 is also equipped with infrared inductor 6，Infrared inductor 6 detects signal，When not having spectators to enter below poly-sound cover，System closes sound，The input of outfan and manipulator 8 that sound collects and records equipment 7 electrically connects，The outfan of manipulator 8 is connected with the input of power amplifier module 9，The outfan of power amplifier module 9 electrically connects with speaker 4 input.
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
