Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the present invention is further illustrated, and the content that execution mode is mentioned not is limitation of the invention.Below in conjunction with accompanying drawing, the present invention is described in detail.
A kind of novel passive radiator audio amplifier provided by the present invention, comprise sound box body, loud speaker and passive radiator, described loud speaker and passive radiator are arranged at the inner chamber of described sound box body respectively, are provided with the ventilating buffering layer 6 air-flow being produced to cushioning effect between described loud speaker and passive radiator.Preferably, described ventilating buffering layer 6 is spongy layer or screen cloth.The shape of ventilating buffering layer 6 is not limit, and can be square circle or other arbitrary shapes, arrange in practical application according to the shape of audio amplifier.Ventilating buffering layer 6 is not defined as sponge or screen cloth, as long as can play buffer gas flow, other gas permeable materials also can be used to substitute, and the permeability of material is determined according to the concrete debugging situation of audio amplifier.In the present invention, spongy layer is the optimal selection material of ventilating buffering layer 6, and spongy layer can weaken the casing resonance caused by standing wave, is equivalent to the effect of filling acoustical cotton in audio amplifier at ordinary times.
Wherein, described sound box body comprises Loudspeaker panel 1, audio amplifier housing 2 and audio amplifier backboard 3, described Loudspeaker panel 1 and audio amplifier backboard 3 removably connect with audio amplifier housing 2 respectively, on described Loudspeaker panel 1 and audio amplifier backboard 3, correspondence is provided with detent (not marking in the drawings) respectively, and the two ends of described ventilating buffering layer 6 are fixed on detent.When assembling, spongy layer being aimed at detent and puts into pressing and putting in place, glue will be stamped in the position that spongy layer contacts with detent bonding fixing further, avoid spongy layer under the promotion of air-flow, depart from original position influence miscellaneous part.
In the present invention, described loud speaker comprises the first loud speaker 4 and the second loud speaker 5, described passive radiator is arranged on the centre of the first loud speaker 4 and the second loud speaker 5, and the ventilating buffering layer 6 be respectively arranged with between described passive radiator and the first loud speaker 4, second loud speaker 5 described in a piece, sound box body is separated into three individual cavity by two-layer ventilating buffering layer 6.As shown in Figure 3, two-layer spongy layer is arranged on the position between loud speaker and passive radiator, the internal cavity of sound box body is divided into three parts, the right and left is respectively the cavity of the first loud speaker 4 and the second loud speaker 5, centre is the cavity of passive radiator, when the first loud speaker 4 and the second loud speaker 5 vibrate at sound box body inside generation stream pressure, air-flow can impact towards middle chamber, and spongy layer produces cushioning effect to air-flow buffer.Air velocity after sponge damping reduces, the motion state of air-flow is slowly extrude to surrounding by quick washing transition, uniformly earth pressure release can be promoted its radiates bass on passive radiator, avoid the air-flow some positions impacted tempestuously on passive radiator and cause rocking vibration to produce different sound.
As can be seen here, the air-flow produced during loudspeaker vibration becomes relatively soft after spongy layer, can not cause fierce impact to passive radiator, significantly can improve the tonequality of low frequency, allow low frequency sound cleaner, the definition of medium, high frequency is also improved accordingly simultaneously.
In the present invention, described passive radiator includes the first passive radiator 7 and the second passive radiator 8, described Loudspeaker panel 1 is provided with three installing holes, described first loud speaker 4, first passive radiator 7 and the second loud speaker 5 are all fixedly installed on Loudspeaker panel 1, corresponding described first passive radiator 7 of audio amplifier backboard 3 offers an installing hole, and described second passive radiator 8 is fixedly installed on audio amplifier backboard 3.Loud speaker is when vibrating, and two passive radiators on this audio amplifier vibrate simultaneously, have better low frequency tonequality.
In the present invention, described first passive radiator 7 and the second passive radiator 8 are symmetrical arranged, air-flow interactional air-flow retaining piece 9 when the centre of described first passive radiator 7 and the second passive radiator 8 is provided with for reducing to vibrate.Described air-flow retaining piece 9 is consistent with the distance of the second passive radiator 8 apart from the first passive radiator 7, influencing each other of the air-flow produced when can effectively reduce the vibration of former and later two passive radiators.
In the present invention, described air-flow retaining piece 9 comprises barrier sheet 10, retainer ring 11 and some braces 12 for connecting described barrier sheet 10 and retainer ring 11, and described barrier sheet 10 is fixedly connected with Loudspeaker panel 1 or audio amplifier backboard 3 by retainer ring 11.Wherein, described air-flow retaining piece 9 is plastic partition block piece, and air-flow retaining piece 9 is one-body molded with audio amplifier backboard 3.Described retainer ring 11 can by glue paste and screw be fixed on Loudspeaker panel 1 or audio amplifier backboard 3, also can with Loudspeaker panel 1 or audio amplifier backboard 3 integrated injection molding.
The above, it is only present pre-ferred embodiments, not any pro forma restriction is done to the present invention, although the present invention with preferred embodiment openly as above, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when utilizing the technology contents of above-mentioned announcement or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, any simple modification that above embodiment is done is referred to according to the technology of the present invention, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
