Description
Technical field
The present invention relates to the medium-high frequency loud speaker of a kind of high pitch loudspeaker and the coaxial setting of Squawker.
Background technology
Present known ribbon tweeters is a rectangular configuration, adopting up and down, two-layer high performance magnetic stripe forms magnetic field in the centre, be covered with the film of loop aluminium strip on surface of therebetween, when alternating current passes through aluminium strip, under the effect in magnetic field, aluminium strip can drive the film up-down vibration and promote air generation sound.Because adopted the structure of magnetic circuit up and down, longer at the stroke of sounding face from the source of sound to the radiating surface, add and on magnetic conductive board, to adopt sound track to spread, and vibrating diaphragm size on the vertical and horizontal direction there is gap, so, from acoustic angle, the directive property of the ribbon speaker of traditional structure is comparatively sharp-pointed, and, say that as monomer it has the difference of vertical and horizontal directive property clearly.And all there is the problem of amplitude and distortion in any ribbon speaker, and then causes its available bandwidth narrower, is mainly reflected in the restriction of medium and low frequency section.
The structure of common ball top type Squawker, as its name suggests, it needs the part (being vibrating diaphragm) on ball top.Because it designs as middle pitch, rise and reach 20000 hertz the sound so its HFS has no idea to resemble ball.And it needs the vibrating diaphragm of ball top shape, so have no idea technically to be designed to coaxial structure with the high pitch of other type.
Summary of the invention
The objective of the invention is to design a kind of medium-high frequency loud speaker with high-fidelity of belt high pitch loudspeaker unit and Squawker unit.
Purpose of the present invention is achieved by designing the coaxial medium-high frequency loud speaker of a kind of belt, the structure of the coaxial medium-high frequency loud speaker of this belt, comprise high pitch loudspeaker unit that is installed on the high pitch support and the Squawker unit that is installed on the middle pitch support, it is characterized in that the high pitch loudspeaker unit is positioned at the centre, the Squawker unit is positioned at the outer shroud of high pitch loudspeaker unit, and both constitute coaxial configuration; The high pitch loudspeaker unit constitutes the magnetic structure in the work magnetic field of high pitch dissipation by annular upper conduction magnetic board, high pitch annular ndfeb magnet and U-shaped magnetic conductive board, and high pitch belt plane diaphragm is installed on annular upper conduction magnetic board; The Squawker unit adopts two circular arc annular middle pitch vibrating diaphragms, constitute T type magnetic structure by middle pitch U-shaped magnetic conductive board, middle pitch annular conducting magnetic column and middle pitch annular ndfeb magnet, middle pitch annular conducting magnetic column is positioned at ring, middle pitch U-shaped magnetic conductive board is positioned at outer shroud, leave magnetic between the two at interval, the middle pitch voice coil loudspeaker voice coil is installed at magnetic at interval, between the going to the bottom of the interior end that middle pitch annular ndfeb magnet is installed in middle pitch U-shaped magnetic conductive board and middle pitch conducting magnetic column, the middle pitch voice coil loudspeaker voice coil is connected with the annular middle pitch vibrating diaphragms of pair circular arcs.
Belt high pitch loudspeaker cell mesh of the present invention, by drive systems belt vibrating diaphragm sounding, its vibrating diaphragm principle is consistent with traditional belt vibrating diaphragm principle, described high pitch belt plane diaphragm can adopt a compound circle spirality planar coil formation on the KAPTON basal plane, make directive property unanimity on the degree directions of plane 360, eliminate the difference of vertical and horizontal, vibrating diaphragm directly radiate by panel simultaneously, eliminated the interference on the stroke, made its directive property more broad than before.
Drive part in belt high pitch loudspeaker unit, the present invention can adopt following technical parameter:
1, described U-shaped magnetic conductive board has 15 °～85 ° interior ring chamfering α.
2, the magnetic interval width H between described annular upper conduction magnetic board and the U-shaped magnetic conductive board is 0.5～15mm.
In Squawker of the present invention unit, the two circular arcs annular middle pitch vibrating diaphragms that adopted, its Internal and external cycle vibrating diaphragm partly adopts the annular design, and suspended portion is the same with traditional ball top shape to adopt annular design.The inner ring diameter A of said pair of circular arc annular middle pitch vibrating diaphragm is 10～200mm, and race diameter B is 15～220mm.And described Squawker configuration of cells has back guide pipe, in order to widen the medium and low frequency of middle pitch.
The present invention adopts belt high pitch loudspeaker unit and Squawker unit coaxial configuration design, its medium and high pitch loudspeaker unit adopts the conventional ADS driving system drive belt vibrating diaphragm sounding after the improvement, its drive part, though still adopt the structure of traditional electrical dynamic formula loud speaker, but but be to utilize its dissipation magnetic field to promote vibrating diaphragm work, just opposite with traditional use.The present invention has simultaneously strengthened air gap as required and the magnetic conduction mode of air gap, the structure of center magnetic conduction sheet has been improved, and can increase the intensity and the uniformity in dissipation magnetic field, improves the sensitivity of loudspeaker and makes actuating force more even, reduces distortion.In Squawker of the present invention unit, novel two circular arc annular middle pitch vibrating diaphragms and improved low distortion T type magnetic structure have been adopted, making it can be coaxial with the belt high pitch loudspeaker unit of any suitable dimension, form point sound source, solve the problem of phase difference, make the reduction of music perfect more.Both reasonable combination make the present invention reach the requirement of high-fidelity on electroacoustic performance, thereby become the medium-high frequency loud speaker of high-fidelity.
