Description
Technical field
The present invention relates to the manufacture method of a kind of audio amplifier, a kind of biplate labyrinth type helps the manufacture method of audio amplifier.
Background technology
Labyrinth type audio amplifier is also called labyrinth audio amplifier or transmission line type audio amplifier, is most commonly that the TDL audio amplifier that Britain produces, and product commercially is the most.This audio amplifier is after the cone of loudspeaker unit, has made the folding mirror pipeline of a square-section, and has been coupled with the medium of surrounding, and the sectional area of sound reproduction pipeline is generally equivalent to the effective area of loudspeaker unit vibrating diaphragm.The audio amplifier of this version and traditional closed audio amplifier and phase inverted cabinet are entirely different when design, and the designing points of this kind of audio amplifier mainly has two principles: one is the fundamental resonance frequency fo that requirement labyrinth type audio amplifier operationally should effectively control loudspeaker unit；Two be requirement labyrinthine system sound reproduction pipeline can promote designed by low-frequency minimum frequency and energy.
Labyrinth type audio amplifier is actually the sound wave of loudspeaker unit reverse side through a long penstock reflection out, and the length of pipeline of raising one's voice to its utmost is the design focus of labyrinth type audio amplifier.Labyrinth type audio amplifier reasonable in design, when loudspeaker unit works, the sound wave given off is as contrary with the acoustic phase before loudspeaker unit, and the playback pipeline in labyrinth should play inhibitory action.When the sound wave given off is consistent with the acoustic phase before loudspeaker unit, the effect of the playback pipeline lifting to be risen of labyrinth type audio amplifier.But labyrinth type audio amplifier also has weak point, importantly structure bulky is complicated, structure is the least to be difficulty with, design the bad phenomenon being easy to the too much overfertilization of low frequency occurs, owing to sound wave to walk the stretch journey of long length in playback pipeline, therefore, to the sensation that a kind of low-frequency velocity of people is the slowest, especially as low frequency drags a upper tail.
Existing labyrinth type audio amplifier is all to have several piece insulation board assembled, is fixed together by adhesive between insulation board and insulation board, makes difficulty, and sound reproduction pipeline cannot accomplish round and smooth nature, thus tonequality is poor, and distortion is big, it is difficult to reach preferable effect.
Summary of the invention
The invention aims to overcome the deficiency of existing labyrinth type audio amplifier, it is provided that a kind of easy to manufacture, the round and smooth nature of pipeline of raising one's voice to its utmost, the emittance of low frequency can be promoted and low frequency dive can be made again to obtain the deepest biplate labyrinth type help audio amplifier.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of biplate labyrinth type helps audio amplifier, and including casing and speaker, the front upper at casing is provided with speaker, it is characterized in that, casing is made up of symmetrical left box body and right case.Two block length cube wooden units equal sized by left box body and right case, being designed with size, the speaker installing hole of position consistency, labyrinth type sound reproduction pipeline and venthole on the medial surface of every block length cube wooden unit, speaker installing hole is connected with venthole by labyrinth type sound reproduction pipeline.
Described speaker installing hole is arranged on the front upper of cuboid wooden unit, and in semicircle shape shrinkage pool, front end is provided with semicircle opening, and rear end is connected with labyrinth type sound reproduction pipeline.
Described labyrinth type sound reproduction pipeline is made up of a sound reproduction pipeline and several sidewalk for visually impaired people communicated therewith, and one end of sound reproduction pipeline is connected with speaker installing hole, and the other end is connected with venthole.
Described sidewalk for visually impaired people at least provided with two, each sidewalk for visually impaired people only one of which and the sound reproduction opening that is connected of pipeline.
The manufacture method helping audio amplifier through upper described biplate labyrinth type is:
(1) selection: selecting hard wood to be processed into sett, smooth plane is dug on surface.
(2) draw: on the upper side of sett, draw out speaker installing hole, labyrinth type sound reproduction pipeline and the profile diagram of venthole.
(3) groove milling: carry out milling groove by the profile diagram drawn on the upper side of side sett with milling machine.
(4) overlay film: cover one layer of cellucotton by adhesive on the surface of institute's milling groove, at venthole one piece of sponge of lining and cloth, to strengthen sound-absorbing effect.
(5) bonding: be integrally fixed by adhesive by two pieces of setts after overlay film, forms casing, sprays one layer of insured's paint in tank surface.
(6) installing: be arranged on by speaker on the speaker installing hole of casing, composition biplate labyrinth type helps audio amplifier.
The invention has the beneficial effects as follows: casing is processed by two symmetrical block length cube wooden units, easy to manufacture, the resonance effect of sound is good, the sound reproduction round and smooth nature of pipeline, tortuous very long, being provided with again several sidewalk for visually impaired people being connected with pipeline of raising one's voice to its utmost, can promoting the emittance of low frequency, low frequency dive to be made to obtain again the deepest.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the sectional structure schematic diagram of the present invention.
In figure: 1 speaker, 2 casings, 21 speaker installing holes, 22 sound reproduction pipeline, 23 ventholes, 24 sidewalk for visually impaired people.
