Abstract
The utility model discloses a traveling receiver, which comprises a casing body and an operating circuit. The operating circuit comprises a common frequency modulation receiver receiving circuit and an intercom receiving circuit, wherein, output terminals of the frequency modulation receiver receiving circuit and the intercom receiving circuit are respectively connected to a voice outputting circuit through a two-way switch, tourists can select to listen to programs of a radio set or explained content transmitted through a transmitting device by a tour guide through the two-way switch, and the programs of the radio set or the explanation of the tour guide is transmitted to the ears of the tourists through earphones of the voice outputting circuit. Compared with the prior art, the traveling receiver has the advantages that the tourists only can receive the explanation of the respective tour guides whereas other tourists not belonging to the tourist party can not be affected, moreover, the operation is convenient, and the function is diversified.
Description
Technical field
The utility model relates to a kind of tourism receiver that receives guide interpreting the visitor on one's body of wearing.
Background technology
When the visitor goes sight-seeing in the scenic spot, often need guide interpreting.At present; each tourist group each has the guide; often have such situation: have simultaneously a plurality of guides respectively separately member to be explained at same sight spot; each guide's sound is interweaved; the visitor just can only hear the noise of complete confusion; not only dissatisfied with the visitor of group, more excuse me think quiet point especially and not with the individual traveler of group.
The utility model content
The purpose of this utility model provides and a kind ofly receives the explanation content that emitted by emitter by the guide, wears tourism receiver on one's body by corresponding visitor, just can only receive guide's separately explanation by the corresponding visitor of this tourism receiver, the visitor of Fei Ben tourist group then can be not influenced.
The technical solution of the utility model is such: a kind of tourism receiver, comprise housing and operating circuit, this operating circuit comprises common FM receiver receiving circuit and intercom receiving circuit, and the output of above-mentioned FM receiver receiving circuit and above-mentioned intercom receiving circuit is connected to the voice output circuit respectively by bidirectional switch.
Above-mentioned voice output circuit comprises low-frequency amplifier circuit and is connected in the earphone of low-frequency amplifier circuit output.
The shared antenna of above-mentioned FM receiver receiving circuit and above-mentioned intercom receiving circuit, and wherein tone frequency channel wire of above-mentioned earphone connects the end that antenna so far is positioned at above-mentioned housing, as the built-in extended line of this antenna.
After adopting such scheme, tourism receiver of the present utility model, utilize common FM receiver receiving circuit and intercom receiving circuit, the output of these two receiving circuits is connected to the voice output circuit by bidirectional switch, the visitor can select the explanation content that will listen to the radio program or listen the guide to emit by emitter by this bidirectional switch, and wireless program or guide's explanation is passed in visitor's the ear by the earphone of voice output circuit.The intercom receiving circuit generally needs long antenna, if antenna is complete when external, the inconvenient guests of long antenna is used, in order to address this problem, the utility model is connected to the end that radio antenna is positioned at housing with a tone frequency channel wire of earphone, as the built-in extended line of this antenna.The utility model compared with prior art, the visitor can only receive guide's separately explanation, the visitor of Fei Ben tourist group then can be not influenced, and have characteristics easy to use, functional diversities.
