Description
Technical field
The utility model is related to bass phase-reversing tube technical fields, are specially a kind of subwoofer phase-reversing tube.
Background technology
It swings to pipe and also makees reflection tube.Industrialized production is circular cutter.There are many method by hand, substantially have and draw
It cuts, two kinds of scroll saw.It is mainly used for when bass is pressurized, bass can be cleaner, and principle is the reverse phase radiated by cone into case
Position sound wave, acts on by babinet, then by swinging to pipe to during external radiation, the sound wave of some of which lower frequency limit can with before cone
The same frequency acoustic phase of radiation approaches, and then the radiation efficiency of loud speaker is improved, so as to extend low frequency response.
The super low voice box of traditional performance labyrinth compression, as a result of closed labyrinth structure, if with traditional
If paraphase hole, since air pressure is bigger when speaker bass cavity works, air velocity and pressure in paraphase hole will
It is very big, thus it is present with the noise that air draught is brought, it is bad is also present with dynamic.
Utility model content

Topic.
To achieve the above object, the utility model provides following technical solution：A kind of subwoofer phase-reversing tube, including body,
Timber partition, phase-reversing tube input port, woofer and bass bugle, the interior side of the body are fixedly installed timber partition, institute
It states timber partition and offers phase-reversing tube input port close to the position on top on the inside of body, the timber partition forms to fall in the inside of body
Phase tube chamber, the inside of the body are fixedly installed phase-reversing tube efferent duct close to the one side of paraphase tube chamber, the body
One side of the inside away from phase-reversing tube efferent duct on the upside of timber partition is fixedly installed woofer, and the inside of the body is in bass
Bass bugle is fixedly installed below loudspeaker, the top of the body is fixedly installed bass chamber close to the position of woofer
External sealing plate.
Preferably, the inside of the body forms bass cavity outside woofer and bass cavity between sealing plate.
Preferably, the bass cavity is connected between each other by phase-reversing tube input port between each other with paraphase tube chamber.
Preferably, the paraphase tube chamber is connected between each other by phase-reversing tube efferent duct with bass bugle.
Preferably, fixed setting is tilted between the timber partition and the inside of body, and the inclination angle of the timber partition is set
Put-degree between.
Compared with prior art, the beneficial effects of the utility model are：
1st, the sucking and discharge of air are carried out using phase-reversing tube input port and phase-reversing tube efferent duct, paraphase tube chamber is passed through in centre
The buffering of body makes the less big speed and pressure of air-flow, by buffer realize air spring effect so that tone color it is soft,
There are dynamic and elasticity and have the compatibility of dynamics.
2nd, sealing plate outside bass cavity is fixed on top.Add the heat dissipation of woofer, add bass cavity and
Extraneous connection, has reached good heat sinking function.
