Abstract
The utility model discloses a frequency modulation radio explaining machine capable of automatic searching, which consists of a transmitter and a receiver and is mainly used by an interpreter of team interpretation and tourists. The explaining machine is characterized in that: the interpreter transmits interpretation contents through the used transmitter, and meanwhile, the receiver used by a tourist searches and locks the frequency range number as same as that of the transmitter through the automatic searching function so as to listen to the interpretation. The explaining machine has small structure, convenience in use, simple operation and moderate price, and is particularly suitable to be used in exhibition halls of various scales and scenic spots.
Description
Technical field
The utility model relates to the wireless interpreter that the explanation of a kind of team is used, the wireless interpreter of the particularly a kind of frequency modulation that can search for automatically.
Background technology
Along with the raising of people's living standard, cultural taste has become the standard of chasing of people's quality of life.The second classroom of being not only people's learning knowledge is visited in tourism, also is the fabulous home to return to that people enjoy high-grade culture life.Come museum, scenic spot, people are satisfied to have a look at rare different treasured or special scene, also wonders their more story, and this just needs the explanation of a standard.Team's explanation mode at most of museums and sight spot is the team that a tourist guide leads ten to 20 visitors, commonplace explanation equipment is that the guide uses public address equipment at present, sound is put outward, like this, visitor's number be can't hear explanation with regard to the visitor who has too much, also has the visitor of a lot " rub and listen ", and environment is more noisy, if the team of visiting is many, also can disturb between the team, be unfavorable for sightseeing.
The utility model content
In order to solve above-mentioned deficiency, the utility model has designed a kind of guide of offering and visitor and has used separately and transmitter and the receiver that links to each other closely arranged again, it is clear that its profile is small and exquisite, simple to operate, transmitter transmits by force, receiver receives sound, and moderate, use at the museum and the scenic spot that can be fit to various scales.
The technical solution of the utility model is achieved in that
1) the wireless interpreter of a kind of frequency modulation that can search for automatically is made up of transmitter and receiver, the audio signal receiver module of transmitter receives external audio signal by its input circuit, and this audio signal is converted into radiofrequency signal launches through processing module, its segment number is frequently searched for and locked to the automatic search module of receiver to the radiofrequency signal of sending, radiofrequency signal is received by the radiofrequency signal receiver module through its input circuit simultaneously, and this radiofrequency signal is converted into audio signal and is optimized through receiver processing module and audio frequency demodulation module, transform the back through D/A again and listens to by sound reproduction equipment.
2) transmitter and receiver can be arranged to 64 groups of different frequency segment numbers, and does not disturb mutually between each frequency range, and like this, a plurality of team visit simultaneously at certain exhibition room or sight spot, just can not interfere with each other.
3) sound reproduction equipment is general dual-channel headphone, convenience.
4) have on the surface of shell of transmitter display screen, button, mains switch, charge port, wire antenna, Mike's input hole, source of sound input hole are arranged, the data of inner operating circuit and button input can show on its display screen.
5) display screen, button, slip volume switch knob, charge port, earphone jack are arranged on the surface of shell of receiver, the data of inner connecting circuit and button input also can show on its display screen.
6) power unit of interpreter adopts the chargeable lithium cell power supply of big capacity light weight.
This utility model designs compared with prior art, and its advantage is:
1) quality of transmitter and receiver all is no more than 80 grams, and it is all very convenient to be that guide or visitor carry.
2) have on the surface of shell of transmitter power switch key, button, display screen, charge port, Mike's input hole, source of sound input port, wire antenna is arranged, wherein button comprises and regulates button and acknowledgement key, makes things convenient for the interpretation staff to regulate; The voice of the on-the-spot explanation of guide can be imported in the Mike input port, and the voice that record in advance can be imported by connecting line in the source of sound input port, can select corresponding input port to carry out the content input according to demand; And have wire antenna can guarantee that the radiofrequency signal of transmitter emission is strong, be identified reception easily; Shows signal power, electric weight and frequency segment number on the while display screen.
3) surface of shell of receiver has button, display screen, charge port, earphone jack, slip volume switch knob, and button comprises adjusting key and acknowledgement key, makes things convenient for the visitor to use; Can shows signal on the display screen, electric weight and segment number frequently.
4) power unit of interpreter adopts light weight, chargeable lithium cell capacious power supply, enables long-time use.
This utility model design is comprehensive, multiple functional, it is as a whole that interpreter is designed to the receiver that the transmitter that used by the guide and visitor use, and the receiver that the visitor uses is designed to be able to the mode of automatic search signal, and the visitor does not need manual operation can search corresponding frequency range.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
According to Fig. 1, the transmitter of the wireless interpreter of frequency modulation that this can be searched for automatically by external shell 1, mains switch 2, charge port 3, Mike input port 4, source of sound input port 5, by wire antenna 6, display screen 7, regulate and subtract key 8, confirm OK key 9, regulate and add key 10 and form.
According to Fig. 2, the receiver of the wireless interpreter of frequency modulation that this can be searched for is automatically subtracted key 16, is confirmed that OK key 17 and adjusting add key 18 and form by external shell 11, slip volume switch knob 12, display screen 13, charge port 14, earphone jack 15, conciliation.
According to Fig. 3 and Fig. 4, when near certain sight spot or single showpiece, explaining, the guide hands this transmitter, and it is arranged to certain segment number frequently in 1 to 64 frequency range by adjusting key 8 and 9, the visitor opens it the receiver in the hand by slip volume switch knob 12, pin and confirm that OK key 17 searches for automatically, it automatically locks after searching the frequency segment number of transmitter, perhaps manually selects by adjusting key 16 and 18; At this moment, the input of the audio signal of transmitter has dual mode: the guide by Mike input port 4 manually explain with the audio signal input with is connected the equipment that has source of sound and imports by will the record audio signal of broadcast of source of sound input port 5, this audio signal is received by the audio signal receiver module by its input circuit, is converted into radiofrequency signal output through processing module; And behind the receiver locking frequency segment number, the radiofrequency signal of transmitter emission is received by the radiofrequency signal receiver module by the radiofrequency signal input circuit of receiver, after processing module and the processing of audio frequency demodulation module, optimizing, transfer audio signal to through D/A again and play, use earphone to listen to; The display screen of while transmitter and receiver shows its operating state by display driver circuit separately, comprises segment number, received signal power, electric weight frequently.
By the connecting circuit continued power, display screen shows electric weight by light weight, chargeable lithium cell capacious in the entire circuit system, if the electric weight deficiency will be charged, charging is to realize by transmitter and receiver charge port separately.
