Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As shown in Figure 1: main noise reduction electric organ 6 is tightly connected in 3 back, main acoustic chamber of three grades of series connection monotubular noise reduction outlet pipes; Main noise reduction electric organ involving vibrations barrier film 9, annular permanent magnet 10, electromagnetism inductive coil 11, shell 12, transformer 13, bridge heap 14, DC relay 15 and storage battery 16; Main noise reduction electric organ vibration diaphragm 9 is fixed on the outside in master's acoustic chamber, exhaust pipe mouth opposite 3; Main noise reduction electric organ vibration diaphragm 9 is bonding with annular permanent magnet 10; Annular permanent magnet 10 inserts in the gap of electromagnetism inductive coil 11; Annular permanent magnet 10 vibrates in the gap of electromagnetism inductive coil 11, and the output terminal of electromagnetism inductive coil 11 is connected with storage battery 16 with DC relay 15 through transformer 13, bridge heap 14, and shell 12 covers on vibration diaphragm 9, annular permanent magnet 10 and the electromagnetism inductive coil 11.
Strong sound wave vibrates winner's noise reduction electric organ vibration diaphragm 9, and vibration diaphragm 9 is bonded as one with annular permanent magnet 10, makes annular permanent magnet 10 in the gap of electromagnetism inductive coil 11, vibrate; Electromagnetism inductive coil 11 is fixed on the main noise reduction electric organ shell 12, and the relative movement in the gap makes magnetic flux change, and produces the induced electromotive force of alternation; In the transformer of sending into 13, become 13-15 volts HV, change the direct current that is higher than 12V into through bridge heap 14; This direct current is that DC relay 15 provides operating voltage; Make normally opened contact K closed, the charging circuit conducting is vehicular power-bottle 16 chargings.If internal-combustion engine quits work, noise disappears, and the power supply of DC relay 15 stops so, and DC relay 15 is in end current potential, and diode stops level voltage to reflux, and normally opened contact K breaks off.Noise reduction electric organ barrier film absorbs after most of acoustic wave energy, and off-gas flows enters into time acoustic chamber 4 successively, further absorbs through time baffler 5; At last; The residue sound wave enters in three grades of acoustic chambeies 7 via exhaust connection 17; Remain major part through three grades of bafflers 19 energy recovery of sound wave; Waste gas finally gets into hush pipes 21 through hush pipe suction tude 20, is discharged by the tailpipe 23 that hush pipe 21 is communicated with, and the low-frequency noise of remnants is leached.
