Accompanying drawing explanation
Fig. 1 is the structural representation that in the utility model, near field of human body communication music shares earphone.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage more clear, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of near field of human body communication music shares earphone, comprise: transmission earphone 100 and reception earphone 200, send earphone 100 and be equipped with independently sending module (not shown), receiver module (not shown), line control push-button 300, audio-frequency module (not shown), power module 400, loud speaker 500, wireless communication module 600 and the first D/A converter module 700 with reception earphone 200.Wherein, sending module and receiver module make one to send earphone 100 can send music to multiple reception earphone 200 simultaneously, and transmission earphone 100 can adopt mode that is wired or bluetooth to be connected with audio-frequence player device 800, is conducive to the experience effect strengthening user.Power module 400 is powered for giving to send earphone 100 and receive earphone 200.
Further, described audio-frequency module is provided with audio interface, audio interface be used for will the audio signal transmission play to loud speaker 500 and the first D/A converter module 700.When the audio signal play enters the loud speaker 500 sending earphone 100 and the first D/A converter module 700 sending earphone 100 by the audio interface sending earphone 100 simultaneously, music play by the loud speaker 500 sending earphone 100, simultaneously, audio signal is converted to digital signal by the first D/A converter module 700 sending earphone 100, and the digital signal after conversion enters the wireless communication module 600 sending earphone 100.If sending earphone 100 is bluetooth earphone, then bluetooth output signal is directly sent to the wireless communication module 600 sending earphone 100, the connection sending earphone 100 and accept earphone 200 can be realized, switch to music sharing model.In actual use, when user appreciates common music, only need open the loud speaker 500 sending earphone 100, other modules are in resting state.Particularly, when send earphone 100 connect audio-frequence player device 800 play music time, other users wear and receive earphone 200 touch transmission earphone 100 user and apply for sharing, music transmission is carried out by Body contact, music can be carried out after obtaining mandate to share, can be implemented in the real-time music realizing many people under only needing the condition of an audio-frequence player device 800 to share, and the compatible all audio-frequence player devices 800 of energy, solve the inconvenience using wired earphone.
Further, wireless communication module 600 comprises programmable system 610, second D/A converter module 620, programmable gain amplifier 630, filter circuit 640 and antenna 650 on sheet.Wireless communication technology is applied to and sends earphone 100, the enjoyment adding music and share can be strengthened.Wherein, on the sheet of transmission earphone 100, programmable system 610 controls the operation of whole transmission earphone 100, is connected the wireless communication module 600 sending earphone 100 by serial ports.Simultaneously, on the sheet of transmission earphone 100, programmable system 610 adopts adaptive multi-rate coding scheme to the digital signal changed by the first D/A converter module 700 or by the Bluetooth signal that bluetooth exports, and the form of convolution code and BCH code hybrid coding is encoded.Modulate digital signal or Bluetooth signal, then through sending the filter circuit 640 of earphone 100, carrying antenna 650 by the plate sending earphone 100, being sent by the signal after modulation, sending frequency range is between 30MHz-100MHz again.
Further, the described earphone 200 that accepts also is provided with audio decoder module 900.The wireless communication module 600 accepting earphone 200 comprises programmable system 610, second D/A converter module 620, programmable gain amplifier 630, filter circuit 640 and antenna 650 on sheet equally.
Specific works principle is as follows: send earphone 100 and support that many people share simultaneously, receive earphone 200 user's body and touch transmission earphone 100 user, and reception earphone 200 user presses the line control push-button 300 received on earphone 200, send and share request, request sends the successfully rear response waited for from sending earphone 100.When there being many people to share demand, send earphone 100 and send authorization response signal by receiving request time order, set up Star Network with reception earphone 200 to be connected, realize the network transport infrastructure of one-to-many, the illegal access device not receiving authorization response signal cannot obtain music information.Receive earphone 200 send request rear waits 10s, exceed the time do not receive from transmission earphone 100 response signal, this asks failure.After transmission earphone 100 receives request, agree to share, press the line control push-button 300 sent on earphone 100, namely license to and receive earphone 20, if refusal, then without the need to operation.After receiving response signal, after both sides' successful connection, wireless communication module 600 is started working, and audio file can be transferred to from transmission earphone 100 and receive earphone 200, realizes music and shares.Sending earphone 100 also can stop music sharing by line control push-button 300 with the user receiving earphone 200, and off device connects.After opening music sharing function, signal is coupled with human body, and is that medium transmits at inside of human body with human body.When the user receiving earphone 200 with send the user of earphone 100 have a Body contact time, Signal transmissions is to receiving earphone 200, and the plate that signal is received earphone 200 carries antenna 650 receives.The filter circuit 640 pairs of signals receiving earphone 200 carry out filtering, the second D/A converter module 620 receiving earphone 200 is input to after signal amplifies by the programmable gain amplifier 630 through receiving earphone 200, enter again after converting digital signal to receive earphone 200 sheet on programmable system 610, demodulation is carried out by programmable system 610 pairs of signals on the sheet of reception earphone 200, be transferred to the audio decoder module 900 receiving earphone 200 again, carry out audio frequency broadcasting by the loud speaker 500 receiving earphone 200.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
