Description of drawings
Fig. 1 looks generalized section for the utility model master.
Among the figure: 1-outlet pipe, 2-interlayer outer wall, 3-master's acoustic chamber, 4-acoustic chamber, 5-baffler, 6-master's noise reduction electric organ, 7-hush pipe, 8-pass through sound dividing plate, 9-electric organ vibration diaphragm, 10-annular permanent magnet, 11-electromagnetism inductive coil, 12-master's noise reduction electric organ shell, 13-transformer, 14-bridge heap, 15-DC relay, 16-storage battery, 17-exhaust connection, 18-tailpipe.
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 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 direct current relay 15 devices through transformer 13, bridge heap 14, and shell 12 covers on vibration diaphragm 9, annular permanent magnet 10 and the electromagnetism inductive coil 11.
Engine operation during internal-combustion engine vent-pipe 1 combustion gas, has also constituted a noise source simultaneously; The hush pipe structure is identical with existing hush pipe, and sound wave is propagated forward, in the process of propagating; Because the horn-like structure of laminated vacuum is adopted in main acoustic chamber 3, sound wave is difficult to appear the acoustic chamber; Main acoustic chamber 3 set inside are passed through sound dividing plate 8, avoid hot air flow directly to impact on the main noise reduction electric organ 6, cause damage.
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 accumulator cell 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 battery tension 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 is discharged through tailpipe 18 by main acoustic chamber 3, inflow time acoustic chamber 4, exhaust connection 17 and hush pipe 7.
The utility model good muffling effect can convert noise energy into electric energy, has realized the conversion and the saving of the energy; Simultaneously simple in structure, be convenient to operation.
