Embodiment
See also Fig. 1, audio frequency broadcast system 1 comprise audio playing apparatus 11 and with the matching used earphone 10 of audio playing apparatus 11.Earphone 10 can adopt wired or wireless mode to carry out communication with audio playing apparatus 11, and wireless communication technique comprises bluetooth, infrared ray etc.In the present embodiment, earphone is headphone and carries out communication with wired mode and audio playing apparatus 11.
See also Fig. 2, headphone 10 comprises audio interface 6, receiver 8, circuit board 9, variable resistor unit 7 and waveform generation unit 12.The sound signal of audio playing apparatus 11 is sent to circuit board 9 by audio interface 6, and by receiver 8 sounding.
See also Fig. 3, variable resistor unit 7 is a flexible member, for example, and the volute spring resistance wire.In the present embodiment, volute spring resistance wire 7 is arranged in the headband 101 of headphone 10, when headphone 10 is won or is put on, volute spring resistance wire 7 is along with elastic deformation occurs in headband 101 in the lump, thereby its spiral winding mutually electrically contacts or is separated from each other and causes the resistance value of volute spring resistance wire 7 to change.
See also Fig. 4, in the Ω of variable resistor unit 7-T electrical properties figure, the c segment table on time shaft shows the state that headphone 10 is not used, and elastic deformation does not occur volute spring resistance wire 7 at this moment, its spiral winding 71 electrically contacts mutually, and its resistance value is minimum value R2.
A segment table on time shaft shows the process that the user puts on headphone 10, and volute spring resistance wire 7 is along with elastic deformation occurs headband 101 in the lump, and its spiral winding 71 is separated from each other gradually, and the resistance value of volute spring resistance wire 7 increases to maximal value R1 gradually.
D segment table on time shaft shows that headphone 10 is held on the state of user's head always, and its resistance value is R1 and remains unchanged.
B segment table on time shaft shows when headphone 10 is won, the resistance change situation of volute spring resistance wire 7, and when putting on headphone 10, the resistance change situation of volute spring resistance wire 7 is opposite.
In one embodiment, see also Fig. 5, be the module map of music playing system 1.This audio frequency broadcast system 1 comprises audio playing apparatus 11, and it comprises audio playing unit 204, processing unit 203, storage unit 205 and waveform generation unit 12, is used for producing analog current or voltage waveform according to the variation of variable resistor unit 7 resistance values.
