Abstract
The utility model discloses a built-in passive double-film phase-reversing tube, which comprises a sealed pipeline, a first passive film, a second passive film and a passive film fixing support. The first passive film and the second passive film are fixed on the passive film fixing support, and fixing positions of the first passive film and the second passive film are arranged on two sides of the bottom end of the sealed pipeline. A passive film is respectively arranged on two sides of the bottom end of the sealed pipeline, due to the fact that arranging positions of the two passive films are opposite, vibration force generated under driving of a loudspeaker is offset, vibration is reduced, and a bass effect is improved under the condition that covered area of a panel is not big.
Description
Technical field
The utility model relates to audio amplifier bass enhancement techniques field, relates in particular to a kind of built-in passive pair of film phase-reversing tube.
Background technology
At present, the bass boost apparatus of audio amplifier generally uses the structure of pipeline type phase-reversing tube or passive film (empty cone).The bass reinforced effects of pipeline type phase-reversing tube is general, and comparatively speaking, passive film bass reinforced effects is better; But shared positions of panels is big, and its casing vibration is stronger, need add big balancing weight and slipmat; Make cost higher, configuration design is restricted, and casing vibrates difficult processing.
The utility model content
To the weak point that exists in the above-mentioned technology, the utility model provides a kind of bass reinforced effects good, and panel occupies little, vibrates built-in passive pair of little film phase-reversing tube.
For realizing above-mentioned purpose; The utility model provides a kind of built-in passive pair of film phase-reversing tube; The pipeline, the first passive film, the second passive film and the passive film fixed support that comprise hermetic type; The said first passive film and the second passive film are fixed on the passive film fixed support, and the fixed position of this first passive film and the second passive film is positioned at the both sides, bottom of said hermetic type pipeline.
Wherein, said passive film fixed support is the passive film fixed support of plastic cement.
The beneficial effect of the utility model is: compared with prior art; The built-in passive pair of film phase-reversing tube that the utility model provides; Respectively install a passive film in the both sides, bottom of hermetic type pipeline, because two passive film installation position opposition, the vibration force that under loudspeaker drive, produces offsets; Reduce vibration, and strengthened bass effect taking under the little situation of panel area.

Fig. 2 is the front view of the built-in passive pair of film phase-reversing tube of the utility model;
Fig. 3 is the built-in passive pair of film phase-reversing tube audio amplifier assembling of a utility model sketch map.
The main element symbol description is following:
1, the passive film of the first passive film 2, second 3, passive film fixed support
4, the pipeline of airtight cavity 5, loudspeaker 6, hermetic type
Embodiment
In order more clearly to explain the utility model, the utility model is done to describe further below in conjunction with accompanying drawing.
See also Fig. 1, Fig. 2 and Fig. 3; The built-in passive pair of film phase-reversing tube that the utility model provides; Pipeline 6, first passive film 1, second passive film 2 and the passive film fixed support 3 that comprises hermetic type; The first passive film 1 and the second passive film 2 are fixed on the passive film fixed support 3, and the fixed position of this first passive film 1 and the second passive film 2 is positioned at the both sides, bottom of hermetic type pipeline 6.
In the present embodiment, passive film fixed support 3 is the passive film fixed support of plastic cement.Certainly, passive film fixed support 3 is not limited to plastic material and processes, and also can adopt other materials; As long as be used for fixing the first passive film 1 and the second passive film 2, make win passive film 1 and second passive film 2 both sides, bottom in the pipeline of seal, receive that loudspeaker drive; Its vibration force can be cancelled out each other; Reduce to vibrate and improve the fixed support of bass effect, all belong to simple deformation or conversion, fall into the protection range of the utility model the utility model.
Situation compared to prior art; The built-in passive pair of film phase-reversing tube that the utility model provides; Respectively install a passive film in the both sides, bottom of hermetic type pipeline, because two passive film installation position opposition, the vibration force that under loudspeaker drive, produces offsets; Reduce vibration, and strengthened bass effect taking under the little situation of panel area.
See also Fig. 3; In the built-in passive pair of film phase-reversing tube audio amplifier assembling sketch map that the utility model provides; In airtight cavity 4, be provided with two loudspeaker 5; And built-in passive pair of film phase-reversing tube; This built-in passive pair of film phase-reversing tube comprises that pipeline 6, first passive film 1, the second passive film 2 and passive film fixed support 3, the first passive films 1 of hermetic type and the second passive film 2 are fixed on the passive film fixed support 3, and the fixed position of this first passive film 1 and the second passive film 2 is positioned at the both sides, bottom of hermetic type pipeline 6.
The built-in passive pair of film phase-reversing tube of the utility model is loaded on airtight audio amplifier front or side, and an end of opening is exposed casing, and be the same with common pipeline type phase-reversing tube assembling.
More than the disclosed several specific embodiments that are merely the utility model, but the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection range of the utility model.
Claims (2)
1. built-in passive pair of film phase-reversing tube; It is characterized in that; The pipeline, the first passive film, the second passive film and the passive film fixed support that comprise hermetic type; The said first passive film and the second passive film are fixed on the passive film fixed support, and the fixed position of this first passive film and the second passive film is positioned at the both sides, bottom of said hermetic type pipeline.
2. built-in passive pair of film phase-reversing tube according to claim 1 is characterized in that, said passive film fixed support is the passive film fixed support of plastic cement.
