Abstract
The utility model relates to a pressure division and pressure regulation type sound box. The utility model is provided with a pressure division and pressure regulation bin which exhausts the jumpy atmospheric air stream of the utility model out of the box body of the utility model by the pressure division and damping action of a damping plate and a phase reversing plate, thus the problem of the sound short circuit of the low and intermediate audio frequency of the existing sound box design is solved, therefore, the exhausted audio frequency is soft and clear, and the air stream pressure is uniform. The utility model is suitable for sound boxes of various types.
Description
A kind of dividing potential drop pressure swing type audio amplifier relates to the improvement of audio amplifier internal structure.
Existing inverted phase type, reflective audio amplifier, owing to fail to solve the acoustic short circuit problem preferably, so low frequency is generally felt deficiency or audio frequency muddiness.Though and labyrinth type, close box audio amplifier audio frequency improved, when the case internal pressure sharply increased and decreased, LF-response can be ended suddenly, it is undesirable to cause low frequency to extend, thereby influences auditory effect.
It is good that the purpose of this utility model provides a kind of LF-response, can correctly reflect the dividing potential drop pressure swing type audio amplifier that audio signal changes, definition is high.
The utility model is to implement like this: it is made up of panel 2 and dividing potential drop transformation storehouse 3 that cabinet shell 1 is wrapped in the band loudspeaker, dividing potential drop transformation storehouse 3 is positioned at the back of panel 2, itself and perverse between a dividing plate 8 is arranged, and many group damping sheets (4,4 ＇), 6 and median septum 5, paraphase plate (7,7 ＇) are arranged in the dividing potential drop transformation storehouse 3, the circular hole of several hollows is arranged on the damping sheet, thereby make case internal gas pressure air-flow reach the requirement of dividing potential drop damping.
The utility model is when the air pressure air communication is crossed dividing potential drop transformation storehouse, because damping sheet and paraphase plate in the dividing potential drop transformation storehouse play the dividing potential drop damping, the interior air-flow of case is become, and pressure is even, tone color is soft, thereby has solved the problem of acoustic short circuit in the audio amplifier design preferably.This reasonable in design, range is wide and clear, is applicable to various types of audio amplifiers.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation in dividing potential drop transformation storehouse.
Shown in accompanying drawing 1,2: the utility model is made up of panel 2 and dividing potential drop transformation bag 3 that cabinet shell 1 is wrapped in the band loudspeaker.Wherein on the basis of cabinet shell 1, band loudspeaker panel 2, increased dividing potential drop transformation storehouse 3, between itself and the loudspeaker dividing plate 8 has been arranged.When the pronunciation cell operation in the audio amplifier, the interior air pressure air communication jumpy of case crosses dividing plate 8 and dividing potential drop transformation storehouse 3 is transferred to outside the casing.There are two damping sheets (4,4 ＇) that have several hollow round hole on the top in dividing potential drop transformation storehouse 3, and median septum 5 is perpendicular on the damping sheet (4,4 ＇); There is a damping sheet 6 with several circular holes the lower part, certain distance with interval and with it the equality place two blocks of independent paraphase plates (7,7 ＇) are arranged, the effect of branch pressure gas stream is all arranged between each plate.
Claims (2)
1, a kind of dividing potential drop pressure swing type audio amplifier, the panel (2) and the dividing potential drop transformation storehouse (3) that are wrapped in the band loudspeaker by cabinet shell (1) are formed, it is characterized in that: dividing potential drop transformation storehouse (3) is positioned at the back of panel (2), between itself and the loudspeaker dividing plate (8) is arranged, and many group damping sheets (4,4 ＇) (6), median septum (5), paraphase plates (7,7 ＇) are arranged in the dividing potential drop transformation storehouse (3).
2, dividing potential drop pressure swing type audio amplifier according to claim 1 is characterized in that: the circular hole that several hollows are arranged on damping sheet (4,4 ＇), (6).
