Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

Please refer to Fig. 1~3, in the embodiment of the present invention, a kind of electronic phase angle silencer, including 1 He of muffler ontology Processing terminal 2 is collected, the muffler ontology 1 includes muffler shell 11, is provided with noise elimination in muffler shell 11 Device inner casing 12, is mounted on central processing unit 13 in the middle part of the upper end of silencer inner casing 12 and lower end, and the one of central processing unit 13 Side is connected with former noise collection device 14, and former noise collection device 14 is mounted on silencer inner casing 12, central processing unit 13 it is another Side is connected with phase noise generator 15, and phase noise generator 15 is mounted on silencer inner casing 12；

And bluetooth module is integrated in the central processing unit 13, central processing unit 13 by bluetooth module by data and Feedback information, which is sent to, collects processing terminal 2, and collecting processing terminal 2 includes display terminal 21 and controlling terminal 22；

Wherein, the thickness of silencer inner casing 12 and muffler shell 11 is usually arranged as 0.8-2mm, can also be according to practical feelings Condition changes thickness, and material can be selected: galvanized steel plain sheet, aluminium sheet, stainless steel plate, rubber, glass or concrete etc.；

Phase noise acoustical generator 15 is a kind of directive property phase noise generator, is configured according to silencer sectional area, usually 2 are configured to, top and bottom are mounted on, convenient uniformly to issue the phase noise with directive property, the instruction for issuing noise comes Derived from central processing unit 13；

Central processing unit 13 is a highly integrated chip module, has been internally integrated bluetooth module, according to former noise collection device 14 collect former noise signal back, and are made an uproar by the analysis to its frequency spectrum, phase harmony energy come the phase for determining that needs are offset Sound, and issued by phase noise generator 15, collection can also be sent by data and feedback information by built-in bluetooth module In processing terminal 2；

Former noise collection device 14 is the device that a kind of audio frequency acquisition instrument and preamplifier are integrated in one, and can be made an uproar to original The characteristics such as frequency spectrum, the phase harmony energy of sound are collected, and are sent to central processing unit 13；
