Abstract
The utility model relates to an intelligent exhibition guiding machine having voice playback function used for the exhibition; the technical proposal is that: a display screen, a keyboard, a power switch and a playback device are installed on a casing panel; a control circuit arranged in the casing comprises an infrared transmittance circuit, a code reception circuit, an accumulator, an SCM and an acoustic frequency demoding circuit. The utility model has simple structure and easy use; the contents of the exhibit can be broadcast by the acoustic frequency demoding circuit through the self-input exhibit coding mode or the infrared frisking the exhibit coding mode; the intelligent exhibition guiding machine is suitable for use in various exhibitions.
Description
Described field
The utility model belongs to the infrared electronic emission and receives instrument, especially a kind of intelligent Audio Guide that is applied to exhibition and has voice play function.
Background technology
People are when visiting various exhibitions and exhibition, often in face of a feast for the eyes exhibition position and showpiece, be at a loss, tend to omit some and oneself want very much the showpiece seen, also usually occur own interested showpiece since more than the people or the quality problem of explaining and publicising the people do not reach the situation of the hope of oneself.Therefore study a kind of exhibition that is convenient for people to attend the show selectively showpiece, to save time, raise the efficiency be very necessary.The equipment of existing guidance exhibition, as browse machine etc., stored finite energy, function ratio is less, can not satisfy people's needs.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of simple in structure, easy to use, can be by play the intelligent Audio Guide of showpiece content from the mode of defeated showpiece coding or infrared search showpiece coding, through audio decoding circuit.
The purpose of this utility model is achieved in that
Display screen, keyboard, power switch and tone playing equipment are installed on case panel, control circuit in the housing is made of infrared transmitter, coding receiving circuit, storer, single-chip microcomputer, audio decoding circuit, store speech data in the storer and this speech data will be broadcasted by tone playing equipment by audio decoding circuit, the duty of each circuit is shown by display screen in the data of keyboard input and the housing.
The interior single-chip microcomputer of housing receives the showpiece coding of importing by keyboard or the corresponding data that extracts in the storer behind infrared transmitter emission infrared signal startup coding receiving circuit reception showpiece coding also broadcasted by the voice of audio decoding circuit with conversion these data by tone playing equipment; Described single-chip microcomputer is a general single chip, and described storer is the FLASH storer, and described audio decoding circuit is the MP3 decoding circuit; Described tone playing equipment is loudspeaker or earphone; Keyboard and display screen all are equipped with backlight circuit; Described infrared transmitter, coding receiving circuit, MP3 decoding circuit, backlight circuit are existing universal circuit; Be equipped with on this control circuit and can connect USB interface of computer.
Advantage of the present utility model and good effect are:
1. the keyboard that is provided with on case panel comprises eight function buttons such as 0～9 numerical key and power switch, playback/search, playback stop/pause, rollback, F.F., rewind down, volume increase, volume down, makes things convenient for the visitor can choose at random skip forward/back, time-out, replay or the like function listening to when explaining orally.But also can listen to simultaneously or use earphone to listen to separately, and regulate volume by keyboard by the many people of on-board speaker.
2. the display screen of She Zhiing can be used for showing that the Audio Guide status information is (as just in the situation of playback, battery electric quantity, volume etc.) and the visitor to the operational circumstances state of keyboard (as the coding of input, key-press status etc.), be convenient to the visitor to grasp the existing situation of Audio Guide immediately; And display screen and keyboard all be provided with backlight circuit, is adapted at using under the dark surrounds.
3. the storer of Audio Guide uses non-volatile FLASH storer, and speech data is not lost in power down.And, can select multiple ratio of compression to speech data employing MP3 compressed format, between capacity and tonequality, find a good equilibrium point.
4. the storer in this Audio Guide housing can connect the peripheral hardware computing machine and upload speech data in this computing machine by USB interface.
Description of drawings
Fig. 1 is the case panel structure synoptic diagram;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the circuit structure theory diagram.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
Referring to Fig. 1 and Fig. 2, this intelligence Audio Guide, constitute by the control circuit in housing 3 and the housing, infrared 1, loudspeaker 2, display screen 4, keyboard 5, power switch 6 and USB interface 7 are installed on case panel, earphone jack 8 and charge port 9 are installed in the side of case panel.
Referring to Fig. 3, the control circuit in the housing mainly is made of the infrared transmitter infrared head of (in have the housing head of being installed in), coding receiving circuit, storer, single-chip microcomputer, audio decoding circuit.Single-chip microcomputer is a general single chip, the pin of this single-chip microcomputer is provided with according to its functions of pins, be connected with FLASH storer (capacity of this storer is decided according to demand), infrared transmitter, coding receiving circuit, MP3 decoding circuit keyboard and keyboard back light circuit, display screen and display backlight circuit, usb circuit of 8～128M Byte etc. respectively, the MP3 decoding circuit is given note amplifier by the D/A conversion with sound signal and is broadcasted by loudspeaker, and this note amplifier also can be realized the earphone broadcast by the earphone jack of case panel side.Usb circuit can be uploaded speech data in the peripheral hardware computing machine by its USB interface.
Total system is powered by voltage-stabilized power supply circuit, and this voltage-stabilized power supply circuit can provide power supply by the battery in the housing, and this battery also can be a rechargeable battery and by the charge port on housing charging, and power switch is used for this power supply of break-make.
Above-mentioned described various circuit and electron device thereof are general proven technique, only require that coupling gets final product, and do not have other concrete technical requirement, therefore do not provide the concrete specification of the circuit diagram or the components and parts of physical circuit.
Using method of the present invention is:
Using method has two kinds.A kind of is at the place, exhibition position of showpiece the showpiece coded transmitter to be installed, the visitor hands this Audio Guide, aim at interested showpiece, press " playback/search " key, at this moment, single-chip microcomputer is received the push button signalling of keyboard, and the infrared head of control " infrared transmitter " sends infrared signal according to the showpiece coded signal that is provided with reception showpiece side to showpiece from the Audio Guide head.Audio Guide starts " coding receiving circuit " immediately and receives the showpiece coding after sending infrared ray, receive the showpiece coding after, the corresponding speech data of searching is directly delivered in " MP3 decoding circuit " and is decompressed in " storer " of Audio Guide; Audio data stream after the decompression transfers the simulating signal that can directly drive earphone to by " digital-to-analog (D/A) conversion ", if use loudspeaker to answer, also needs by " note amplifier " this signal to be amplified to drive loudspeaker.
Another kind of using method is: the visitor hands Audio Guide, directly import near the numbering (the showpiece numbering generally can be built up in the showpiece by the form of label) of showpiece, by " playback " key, after single-chip microcomputer was received the numbering of input, control MP3 decoding circuit was by earphone or loudspeaker playback.
