Abstract
The utility model discloses a wireless headset system which comprises a processing unit, a transmitter unit and a receiver unit. The transmitter unit and the receiver unit are respectively connected with the processing unit. The transmitter unit is an AS6200 chip, and the receiver unit is an AS6600 chip. The wireless headset system is mainly applied to activities such as music enjoyment, audio transmission, children care, etc, in houses, schools, venues, internet bars, etc, and is not only capable of achieving full-duplex real-time call functions which cannot be achieved by ordinary walkie-talkies, but also is capable of receiving FM stereo radio. At the same time, the wireless headset system can be widely used with household appliances such as TVs, DVDs, computers, etc, can singlehandedly achieve recreational call functions, and can be built in platforms such as MP3, MP4, mobile phones, GPS, etc, for multi-user interactive communication.
Description
Technical field
The utility model relates to a kind of wireless headset, relates in particular to a kind of full duplex stereo wireless headphone system.
Background technology
Because wired earphone is subjected to the restriction of line, bring inconvenience for work and life, wireless headset is subjected to user's favor gradually.An existing wireless headset part is not with microphone; Another part provides the function of microphone, but the band microphone also normally adopt semiduplex mode, it is not too convenient to use.
The frequency of existing wireless headset can overlap with other frequencies usually, disturbed by it when voice-enabled chat, can't guarantee good speech quality.
In addition, another weak point of existing wireless headset is that it can not provide stereo channel.
The utility model content
Technical problem to be solved in the utility model is: a kind of stereo wireless headphone system that can realize the real-time call function of full duplex is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of wireless headphone system, it comprises processing unit, transmitter unit, reaches receiving element, and described transmitter unit and receiving element are connected with processing unit respectively.
As a kind of preferred version of the present utility model, described transmitter unit is a transmitting chip; Further, described transmitting chip is the AS6200 chip.
As a kind of preferred version of the present utility model, described receiving element is a receiving chip; Further, described receiving chip is the AS6600 chip.
As a kind of preferred version of the present utility model, described processing unit is set number of digital signal input output end mouth and corresponding frequency range thereof.
As a kind of preferred version of the present utility model, the frequency range of described digital signal input/output port correspondence is smaller or equal to 87MHz or more than or equal to 108MHz; Further, the frequency range of described digital signal input/output port correspondence is at 70-87MHz or 108-102MHz.
As a kind of preferred version of the present utility model, the frequency range of described digital signal input end mouth correspondence is at 70-87MHz, and the frequency range of digital signal output end mouth correspondence is at 108-102MHz; Perhaps, the frequency range of described digital signal input end mouth correspondence is at 108-102MHz, and the frequency range of digital signal output end mouth correspondence is at 70-87MHz.
As a kind of preferred version of the present utility model, described wireless headphone system also comprises a LCD who is connected with described processing unit; Described transmitter unit and receiving element are connected with processing unit by I2C (Inter-IC) bus respectively.
The beneficial effects of the utility model are: the utility model is mainly used in activities such as the audio-visual appreciation, voice transmission, child's monitoring of family, school, meeting-place, Internet bar; Both can realize the function of the real-time conversation of full duplex that common walkie-talkie can't be realized, also can receive FM stereophonic broadcasting.The household electrical appliances such as TV, DVD, computer of can arranging in pairs or groups widely simultaneously use, and also can realize having recreational call function separately, can be built in MP3 simultaneously, and MP4, mobile phone, platforms such as GPS are used for a plurality of user interactions and exchange.

Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, the utility model has disclosed a kind of wireless headphone system, and it comprises processing unit 1, transmitter unit 2, reaches receiving element 3, and described transmitter unit 2 and receiving element 3 are connected with processing unit 1 by I2C (Inter-IC) bus respectively.
Described transmitter unit 2 is a transmitting chip, and this transmitting chip is the AS6200 chip, and its composition can be consulted Fig. 3; Described receiving element 3 is a receiving chip, and this receiving chip is the AS6600 chip, and its composition can be consulted Fig. 4.Because these two analog ports that chip all has two sound channels make wireless headphone system that good stereophonic effect can be arranged.In addition, based on the special setting of AS6200 and AS6600, can also be implemented between the frequency of 300Mhz to 400Mhz and carry out the FM intercommunication.
Described processing unit MCU is provided with some groups of key switches in order to set GPIO (digital signal input/output port), comes setpoint frequency with this, all is provided with 4 as receiving and send button, even heavy platform is arranged, also can override, and is easy to operate.
The frequency range of described each digital signal input/output port correspondence is smaller or equal to 87MHz or more than or equal to 108MHz; In the present embodiment, the frequency range of described digital signal input end mouth correspondence is at 70-87MHz, and the frequency range of digital signal output end mouth correspondence is at 108-102MHz; Certainly, also can be provided with like this: the frequency range of described digital signal input end mouth correspondence is at 108-102MHz, and the frequency range of digital signal output end mouth correspondence is at 70-87MHz.Because it is far away that above-mentioned working frequency range is set, and avoided the interference of FM common frequency band simultaneously, guaranteed calling quality.
Simultaneously, described wireless headphone system can also be provided with a LCD who is connected with described processing unit.
The utility model is mainly used in activities such as the audio-visual appreciation, voice transmission, child's monitoring of family, school, meeting-place, Internet bar; Both can realize the function of the real-time conversation of full duplex that common walkie-talkie can't be realized, also can receive FM stereophonic broadcasting.The household electrical appliances such as TV, DVD, computer of can arranging in pairs or groups widely simultaneously use, and can also realize having recreational call function separately, can be built in MP3 simultaneously, and MP4, mobile phone, platforms such as GPS are used for a plurality of user interactions and exchange.In addition, the setting of AS6200 chip and AS6600 chip can make earphone that good stereophonic effect is arranged.
