Abstract
The utility model relates to an infrared induction automatic sound transmitter. The utility model is characterized in that the infrared induction automatic sound transmitter comprises a control box (2); the control box (2) is internally provided with a battery (3), a singlechip (4), a loudspeaker (5) and a card reader (6); an infrared distance measurement inductor (1) is arranged at the center of a panel of the control box (2); the card reader (6) is connected with an input interface and an output interface of the singlechip (4); the infrared distance measurement inductor (1) is connected with the input interface of the singlechip (4); and the loudspeaker (5) is connected with the output interface of the singlechip (4). The infrared induction automatic sound transmitter has strong practicability, can automatically induct the visitor and play the exhibit introduction, can not only saving a great deal of manpower but also enhance the exhibit effect and can play a very obvious role in the exhibit industry.
Description
Technical field
The utility model relates to broadcaster, is a kind of infrared induction automatic audio speaker specifically.
Background technology
Modern's work has a varicolored life, and various exhibition is more and more.In order to understand showpiece to the visitor, often sponsor all needs to be equipped with some narrators.In practice, the visitor arrives at random, and narrator's explanation may have been carried out half, wants from the beginning to listen to wait for a long time, and therefore wastes many times; Another kind of situation is, showpiece is a lot, and the narrator seldom, be impossible all stand a narrator's before every showpiece like this, see and the visitor chooses the showpiece of oneself liking mostly, and do not have the narrator to explain orally before the showpiece, will influence the understanding of visitor like this showpiece.And analogue is also arranged in school: if do the science popularization exhibition, if do not have teacher to explain before the panel, the student just is difficult to understand and understand.So, need a kind of equipment that can broadcast automatically and explain.
Summary of the invention
The purpose of this utility model provides a kind of convenient and practical infrared induction automatic audio speaker.
Described infrared induction automatic audio speaker is characterized in that: this infrared induction automatic audio speaker comprises a control enclosure; Battery, single-chip microcomputer, loudspeaker and card reader are installed in the described control enclosure, an infrared distance measurement inductor is installed by the panel central authorities of control enclosure, wherein card reader links to each other with the IO interface of single-chip microcomputer, the infrared distance measurement inductor links to each other with the input interface of single-chip microcomputer, and loudspeaker links to each other with the output interface of single-chip microcomputer.
This device need cooperate by the built-in program of single-chip microcomputer finishes function corresponding.
The utility model is practical, can respond to the visitor automatically, plays the showpiece introduction automatically, not only saves a large amount of manpowers, more can strengthen bandwagon effect, to showing the effect highly significant of industry.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the utility model electrical principle block diagram.
Among the figure: 1-infrared distance measurement inductor, 2-control enclosure, 3-battery, 4-single-chip microcomputer, 5-loudspeaker, 6-card reader.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: infrared induction automatic audio speaker as shown in Fig. 1,2 comprises a control enclosure 2; Battery 3, single-chip microcomputer 4, loudspeaker 5 and card reader 6 are installed in the described control enclosure 2, an infrared distance measurement inductor 1 is installed by the panel central authorities of control enclosure 2, wherein card reader 6 links to each other with the IO interface of single-chip microcomputer 4, infrared distance measurement inductor 1 links to each other with the input interface of single-chip microcomputer 4, and loudspeaker 5 links to each other with the output interface of single-chip microcomputer 4.Described single-chip microcomputer 4 can use ARM, DSP or other intelligent processor to replace, also can plug-in D/A, and modules such as sound circuit.
Electrical principle block diagram below in conjunction with Fig. 2 carries out the principle explanation.
First-class battery 3 in battery case covers the lid of battery case, enters normal state to be controlled after system's power supply.Control enclosure 2 is fixed on the top of showpiece or panel, simultaneously infrared distance measurement inductor 1 is aimed at showpiece the place ahead.
The explanation recording of prerecording is stored on the storage card, and is inserted into card reader 6.
As people during near showpiece, infrared distance measurement inductor 1 is sent to single-chip microcomputer 4 with detected data, after single-chip microcomputer 4 is analyzed data, before if the finder is trapped in showpiece, and when no longer mobile, to regard as the visitor and want to understand showpiece, single-chip microcomputer 4 was just controlled card reader 6 and was read explanation recording data in the storage card this moment, and control loudspeaker 5 plays back again.
When infrared range finding inductor 1 detects personnel and leaves, consequential signal is passed to single-chip microcomputer 4, after single-chip microcomputer 4 was analyzed data, control loudspeaker 5 stopped to play.
The utility model also can be used for school's aided education.
