The utility model content
In order to solve the demand; The utility model has been designed and developed a kind of wireless explanation controller that can offer narrator's use and can carry out band shifting; This controller is united use with the broadcast main frame; Reach the sound that amplifies and can cover whole exhibition room, and can carry out the adjusting of 256 frequency ranges; This controller profile is small and exquisite, both artistic and practical, both can manual adjustments segment number frequently, can regulate and play the frequency segment number of main frame coupling again automatically, dual mode is also arranged aspect input simultaneously, both can artificial explanation phonetic entry also can play the internal memory phonetic entry.
The technical scheme of the utility model is achieved in that
1) be made up of controller housing and inner each functional module based on 256 adjustable wireless explanation controllers of frequency range: the inner functional module of controller housing comprises audio-frequency signal processing module, infrared receiving module, infrared decoder module, supply module, display module, keyboard encoding and decoding processing module, USB module, controlled in wireless transmitter module, voice modulation module, radiofrequency emitting module and memory module; When the infrared receiving module of controller receives infrared signal; Can it be decoded through infrared decoder module; Handle and the controlled in wireless transmitter module through CPU again; Control it and regulate segment number frequently automatically; The sound signal of artificial simultaneously explanation or storage is converted into the ANTENNAUDIO radiofrequency signal through CPU, voice modulation module, radiofrequency emitting module and launches; The sound signal of storaged voice is through keyboard input signal, and process keyboard encoding and decoding processing module and CPU access from memory module after handling again.
2) controller can be adjusted to 256 different frequency ranges, and does not disturb mutually, is fit to a plurality of explanation team and carries out simultaneously.
3) two kinds of wireless signals of controller emission are respectively that controlled in wireless transmits and ANTENNAUDIO transmits, through the controlled in wireless segment number frequently that automatically adjusts that transmits, through the ANTENNAUDIO emission explanation content that transmits.
4) input of controller has dual mode, is respectively Mike and explains input and internal memory phonetic entry, can freely switch.
5) display screen of controller is the very color liquid crystal display of TFT, can show related content.
6) have on the control circuit of controller and can connect the peripheral hardware USB interface of computer, carry out the input of voice content.
7) power unit of controller adopts the chargeable lithium cell power supply.
This utility model designs compared with prior art, and its advantage is:
1) controller has dual transmitting, and promptly can reach the function of automatic adjusting frequency range and the function of emission of radio frequency signals and carry out simultaneously.
2) frequency range of controller can be adjusted to 256 at most, and suitable a plurality of exhibition rooms, venue use simultaneously, and do not disturb mutually.
3) input signal of controller can be that artificial explanation phonetic entry and internal memory are play the phonetic entry dual mode, can freely switch, and is fit to different explanation occasions.
4) display screen of controller adopts very color liquid crystal display, clear display, and resolution is high.
5) controller also can be regulated segment number frequently through the mode of digital keys, can be adjusted to 256 frequency ranges at most.
6) the controller good looking appearance, be convenient for carrying, power unit adopts light weight, chargeable lithium cell capacious power supply, enables long-time use.
This utility model design is comprehensive, novel; Consider the weak point of existing team explanation electronic equipment; Be designed to him a kind ofly not only can play the internal memory voice, but also can play the voice of artificial explanation; Can also realize the mode that 256 frequency range automatic or manuals are regulated, and this controller profile is small and exquisite, attractive in appearance, is fit to very much the narrator and carries.
