The device provides the method for sharing music by two people, the distance between people is shortened, the low distortion during sound source transmitting is maintained, and an audio control switch can be turned on through body contact to achieve the effect for sharing the music.
Description
Technical field
The present invention relates to the shared music of a kind of music apparatus, more particularly to a kind of wired or wireless earphone or audio amplifier
Device.
Background technology
The radiotechnics that at present Radio earphone is adopted has：Bluetooth, wifi, Zegbee, NFC, FM, GFSK are red
Outside line, the magnetic line of force, and other wireless technologys.There are transmitting and receiving terminal.Transmitting terminal connects source of sound, Jing process and modem section transmitting
To aerial, one or multi-section receiving terminal demodulation and broadcast source of sound reduction, Jing loudspeaker after processing after each receiving.Received with family
Transmitting terminal pattern：1., a transmitting terminal is to a receiving terminal；Or 2., broadcast type receive, i.e., a transmitting terminal is to multiple receiving terminals.
Problem is：When first and second liang of people listen together same a piece of music/song, radio broadcasting pattern, i.e., one are typically adopted
End is penetrated, multiple receiving terminals can be matched somebody with somebody, but when two people each listen music/song together, thought at that time while sharing the same of other side
Music/song, need to exchange the player of other side or earphone and other side, or in other side's player many plugs in parallel, other side
Music/the song can just be heard.It is very inconvenient.1. research find, one group of transmitting terminal is added in receiving terminal, and newly sets one grade
For actively（MASTER）/ driven（SLAVE）Shelves arrange the shared model for family.Example：Based on Party A is arranged（MASTER）, Party B
Be set to from（SLAVE）Pattern, receiving terminal receives music/song that player is transmitted in Party A's earphone, and Jing Party A transmitting terminal is passed
It is sent to Party B's receiving terminal and plays out the music/song.2. research find：Player transmits music to main Party A（MASTER）, then
Jing human bodies after this source of sound modulation are transmitted the modulated signal by Party A, by such as leading along by hand signal from Party A with the contact of Party B's body
Passed to after receiving terminal is demodulated and processes in Party B's earphone by human body and broadcast the source of sound from loudspeaker.But due to from person transmission
During, noise and noise are generated, this noise and noise are difficult to solve.To solve this problem.Passed to by human body from Party A
Party B only transmits control music switch signal and pairing code signal.Music signal is not transmitted.Which solve noise in transmittance process
Problem.And music communication is still with wireless system from aerial transmission.
