Feedforward, after feedback mixing foot, reset out sound via loudspeaker 15.Meanwhile, feedback microphones 132 pickup is to surrounding
After sound, via feedback microphones gain module 1311, signal is done suitably amplification and lead to after feedback noise reduction circuit 1312 processes again
Cross the loudspeaker 15 contrary sound of amplitude equal phase of resetting and realize noise reduction.
23) double listen pattern to switch to degree of depth noise reduction mode: user is again to 22) described in side stir three-dimensional again and dial
After dynamic button, pattern can be listened to switch to degree of depth noise reduction mode from double intelligent earphone.User is again to 32) described in side stir
After three-dimensional stirs button again, three-dimensional is stirred SAN GUAN SW3 of button and is again closed merga pass outfan 143 output low level
Signal, the PIO3 mouth of micro controller unit 11 receives this low level signal, and micro controller unit 11 controls two-way by PIO4 mouth
The first input end SW4 of switch 16 disconnects and the second input SW5 Guan Bi, and micro controller unit 11 is opened by I2C mouth simultaneously
Feedforward microphone gain module 1211, feed forward noise reduction circuit 1212, feedforward microphone 122, feedback microphones gain module 1311,
Feedback noise reduction circuit 1312 and feedback microphones 132, after feedforward microphone 122 pickup to surrounding sound, by feedforward wheat
Signal is done after suitably amplifying by gram wind gain module 1211, processes via feed forward noise reduction circuit 1212 and passes through the second input
SW5 output is to feedforward, feedback mixing foot, then is released with the outside noise amplitude phase heard with ear on ear limit by loudspeaker 15
The contrary sound of equiphase is to realize noise reduction.Meanwhile, after feedback microphones 132 pickup to surrounding sound, by instead
Signal is done after suitably amplifying by feedback microphone gain module 1311, processes via feedback noise reduction circuit 1312 and is reset by loudspeaker 15
Go out the contrary sound of amplitude equal phase to realize noise reduction.
In another embodiment as a example by the mode of operation that uses first is for degree of depth noise reduction mode, its work process is with aforementioned
21)-23) something in common repeats no more, and now difference is illustrated:
24) degree of depth noise reduction mode switches to double pattern of listening: user is to aforesaid 22)-23) opposite side stirs one time three
After stirring button, intelligent earphone can be switched to from degree of depth noise reduction mode and double listen pattern.When user is to aforesaid 22)-23)
Opposite side is stirred after a three-dimensional stirs button, and three-dimensional is stirred the first pass SW1 of button and closed merga pass outfan 141 and export
Low level signal, after the PIO1 mouth of micro controller unit 11 receives this low level signal, micro controller unit 11 is by PIO4 mouth
The first input end SW4 Guan Bi and the second input SW5 that control two-way switch 16 disconnect, and close feedforward fall by I2C mouth simultaneously
Noise cancellation circuit 1212 opens feedback microphones gain module 1311, feedback noise reduction circuit 1312 and feedback microphones 132 simultaneously, and first
Input SW4 Guan Bi and the second input SW5 disconnect, after feedforward microphone 122 pickup to surrounding sound, by feedforward wheat
Signal is done suitably amplification by gram wind gain module 1211, and after filter circuit 17, two-way switch 16, output is to feedback noise reduction core
After the feedforward of sheet 131, feedback mixing foot, reset out sound via loudspeaker 15.Meanwhile, feedback microphones 132 pickup is to week
After enclosing ambient sound, via feedback microphones gain module 1311, signal is done suitably amplification again at feedback noise reduction circuit 1312
Noise reduction is realized by the loudspeaker 15 contrary sound of amplitude equal phase of resetting after reason.
25) the double switched on mode playback of pattern of listening: user is to aforesaid 22)-23) opposite side stirs a three-dimensional again
After stirring button, intelligent earphone can be listened the switched on mode playback of pattern from double.When user is to aforesaid 22)-23) contrary one
Side is stirred after three-dimensional stirs button again, and three-dimensional is stirred the first pass SW1 of button and again closed merga pass outfan 141 and export
Low level signal, the PIO1 mouth of micro controller unit 11 is closed feedback microphones by I2C mouth after receiving this low level signal and is increased
Benefit module 1311, feedback noise reduction circuit 1312, feedback microphones 132 and feed forward noise reduction circuit 1212, feedforward microphone 122 picks up
After surrounding sound, by feedforward microphone gain module 1211, signal done suitably amplification, by filter circuit 17, double
After way switch 16, after exporting the feedforward to feedback noise reduction chip 131, feedback mixing foot, reset out sound via loudspeaker 15.
In another embodiment by the mode of operation used first be double listen pattern as a example by, its work process and aforementioned 21)-
25) something in common repeats no more, and existing difference is illustrated: when intelligent earphone be in double listen pattern time, by three-dimensional
The both sides stirring button are stirred once respectively so that intelligent earphone can go out double listen pattern switch to degree of depth noise reduction mode or from hold concurrently
Listen the switched on mode playback of pattern.
Refer to the structural representation that Fig. 2, Fig. 2 are this utility model another embodiments of intelligent earphone, the arrow side in figure
To representing sense.Intelligent earphone shown in Fig. 2 is roughly the same with shown in Fig. 1, and the most no longer this repeats thus like part
, now difference is illustrated.In this utility model intelligent earphone, micro controller unit 11 also comprises storage as shown in Figure 2
Module and bluetooth module;The mode of operation that memory module storage intelligent earphone is current, closes when user and is then turned on intelligent earphone
Or when being switched to after another mode of operation from current mode of operation and exit another mode of operation, micro controller unit 11 is arranged
Intelligent earphone works under the mode of operation of storage, and such as present mode is double pattern of listening, and memory module can store works as front mould
Formula is double to listen pattern, when user close be then turned on intelligent earphone after micro controller unit 11 to arrange intelligent earphone be double to listen mould
Formula;Micro controller unit 11 receives, by bluetooth module, the instruction letter that the APP module of high in the clouds data host or mobile device sends
After number, micro controller unit 11 controls feed forward noise reduction unit according to command signal and/or feedback noise reduction unit start makes described
