Length regulates more accurately.In the present embodiment, by the entire length of phase-reversing tube is regulated, make down
The entire length of pipe is elongated mutually or shortens, so that phase inverted cabinet obtains different bass audio effects.
Wherein, casing 5 lateral surface is provided with control knob, is used for controlling drive mechanism 3 and drives secondary phase-reversing tube 2
Axial direction back and forth movement along main phase-reversing tube 1.For example, it is possible to control drive mechanism 3 by control knob
Internal transmission guide rod 32 rotates clockwise or rotates counterclockwise, when transmission guide rod 32 is carried out clockwise
During rotation, secondary phase-reversing tube 2 is driven to move along the axial direction leaving main phase-reversing tube 1, so that phase-reversing tube
Entire length is elongated, when transmission guide rod 32 rotates counterclockwise, drives secondary phase-reversing tube 2 to fall along tending to master
The axial direction motion of pipe 1 mutually, so that the entire length of phase-reversing tube shortens, by phase-reversing tube entire length
Change change phase inverted cabinet tonequality.
Wherein, the bottom of casing 5 is provided with bellmouth orifice 6, and bellmouth orifice 6 is arranged above loudspeaker 7.Work as loudspeaker
During 7 work, producing air-flow, air-flow flows out outside casing 5, corresponding with the duty of loudspeaker 7, air-flow from
Flow out the speed outside casing 5 in casing 5 and blast has critically important impact to the tonequality of phase inverted cabinet.
The phase-reversing tube structure of this utility model offer and phase inverted cabinet, this phase-reversing tube structure includes main phase-reversing tube
With secondary phase-reversing tube, main phase-reversing tube is connected with secondary phase-reversing tube, and main phase-reversing tube can relative movement with secondary phase-reversing tube.Logical
Cross the relative movement between main phase-reversing tube and secondary phase-reversing tube so that the entire length variable length of phase-reversing tube or shorten,
The change of phase-reversing tube entire length makes phase inverted cabinet can obtain different bass audio effects, thus meets
The consumer's different requirements to audio.
Above example is to realize the preferred embodiment of technical solutions of the utility model, the ordinary skill of this area
Personnel should be appreciated that can do suitable adjustment according to thought of the present utility model and spirit to detailed description of the invention
