The utility model content
In order to solve the demand, the utility model has been designed and developed a kind of wireless receiver that can offer the visitor of team use, this equipment carries out wireless receiving technology and hardware device integrated, be designed to a kind of wireless receiver small and exquisite, easy to carry, have and to mate, receive signal distance characteristics far away automatically, the team's explanation that is particularly suitable for tourist attraction, museum is used, and also is fit to use with a team that tourism is visited.
The technical solution of the utility model is achieved in that
1) extra small supra-aural wireless receiver is made up of receiver housing, enclosure interior control circuit and earphone, and internal control circuit is made of MCU control unit, radiofrequency signal identification receiving element, button and connecting circuit part, charge port and connecting circuit part thereof, power unit, audio signal demodulating unit, D/A converting unit; Outside has volume adjusting key, mains switch, earphone composition, behind radiofrequency signal identification receiving element reception transmitting terminal signal, after the processing of MCU control unit, is converted into sound and plays by earphone.
2) power unit of receiver adopts the chargeable lithium cell power supply, can charge repeatedly, uses environmental protection.
3) on the control circuit of receiver the charge port that can connect the peripheral hardware charging device is arranged.
4) the volume adjusting key be respectively independently volume add key and volume down key, when making things convenient for the visitor to use the operation.
5) receiver housing and earphone can be designed to one, need not line, the transmission sound stable.
6) hook on the earphone and earplug can be changed, and be convenient and healthy.
This utility model designs compared with prior art, and its advantage is:
1) this equipment has carried out Radio Transmission Technology and hardware device integrated, is integrated in the volume compact housing, and is easy to carry.
2) effective receiving range of this equipment is greater than 80 meters.
3) receiver is furnished with removable hook and earplug, and is convenient, healthy.
4) power unit adopts light, the capacious chargeable lithium cell power supply of quality, enables long-time use.
This utility model is skillfully constructed, receiver is designed to a kind of small and exquisite supra-aural, the visitor of team can carry, be arranged to the signal with frequency range with tourist guide or guide, listening to the unified of tourist guide or guide transfers and explanation, this equipment quality is light, easy to carry, and safety and sanitation are the trend of the development of team's explanation from now on.
