Description
Technical field
The utility model belongs to speaker field, and speaker can be converted specifically, being related to a kind of band positive and recommending air
Case.
Background technology
The form of loudspeaker acoustic enclosure generally can be divided into closed, paraphase, labyrinth and the forms such as passive at present.Various speakers are set
Meter is provided to negative wave caused by isolation loudspeaker unit behind, is superimposed and supports with the positive wave of front output after avoiding its diffraction
Disappear effective output.Though the antiphase wave at the loud speaker back side can be isolated in the speaker design of above several forms, due to loud speaker list
Member loads onto the air damping that must pull against after babinet in babinet and carrys out work done, and damping action exists caused by negative wave when work in case
On the diaphragm of loudspeaker, very big interference is caused to vibrating diaphragm, so that harmonic frequency of loudspeakers is increased, transient response degenerates, harmonic distortion
Increase.Though paraphase, labyrinth and passive speaker can effectively increase low frequency output, its output frequency response curve is not flat enough
Directly, distortion is big.
In view of this special to propose the utility model.
Invention content
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a kind of band positive to recommend sky
