Description
Technical field
The present invention relates to the technical field of electro-acoustic transducer device, the Suspensible loud speaker of a kind of both sides pronunciation specifically.
Background technology
Coil-moving speaker is also called dynamic speaker.Its operation principle is according to Faraday's law, and when current-carrying conductor is by magnetic field, can be subject to an electric power, its direction meets not carrys out bright left hand rule, and power and electric current, magnetic direction are orthogonal, and stressed size is directly proportional to electric current, conductor length, magnetic flux density.When voice coil loudspeaker voice coil input alternation tone currents, voice coil loudspeaker voice coil is subject to alternation motive force and produces alternate motion, drives cone vibration, repeatedly promotes air and sounding.And in voice coil vibrations process, reduce the important indicator that voice coil loudspeaker voice coil deviation is radially guarantee sounding tonequality.
And in the dynamic speaker of prior art, its voice coil loudspeaker voice coil is often directly placed in the centre bore of drive magnet, or voice coil loudspeaker voice coil is placed on outside the conducting magnet core of a column, and in order to reduce the frictional force between voice coil loudspeaker voice coil and magnet, therefore, larger glade plane space must be left between its voice coil loudspeaker voice coil and magnet.This just causes voice coil loudspeaker voice coil deviation radially in vibration sounding process comparatively large, thus causes the misalignment of sound.
Summary of the invention
Technical problem to be solved by this invention is: provide the Suspensible loud speaker pronounced in a kind of both sides, in its voice coil vibrations voiced process, voice coil loudspeaker voice coil deviation is radially little, thus making sounding tonequality better, the broad covered area of bilateral pronunciation simultaneously, is convenient to be arranged at eminence by hook.
The technical solution used in the present invention is: provide the Suspensible loud speaker pronounced in a kind of both sides, it comprises substrate, be symmetrically set in two frame of substrate both sides, a sound generating mechanism is provided with all separately in the frame of each side, substrate is provided with the hook of circular arc, the lower end of hook is connected with substrate by a straight-bar, sliding-off proof mechanism is provided with in hook, described sound generating mechanism comprises cone, magnetic conductive board, drive magnet and the Voice coil assemblies for driving cone to vibrate, described drive magnet is clamped between substrate and magnetic conductive board, the osculum end of magnetic conductive board and the nearly substrate of frame is fixed, cone is set up in frame, and the outer rim of cone one end and the big opening end of frame are fixed, described Voice coil assemblies comprises centre pilot cover, at least Liang Ge magnetic conductive core column and the voice coil loudspeaker voice coil be wound on each magnetic conductive core column lateral wall, drive magnet is provided with the storage tank of accommodating Voice coil assemblies, axial location along storage tank in storage tank is fixed with a guide pillar, centre pilot cover is slidably fitted on guide pillar, and one end of centre pilot cover is connected with the other end of cone is removable by the first connecting plate, the circumference of whole magnetic conductive core columns centrally fairlead axis is uniformly distributed, one end and first connecting plate of magnetic conductive core column are fixed, the magnetic conduction sleeve be slidably matched with the magnetic conductive core column with voice coil loudspeaker voice coil is provided with in storage tank, one end and the substrate of magnetic conduction sleeve are fixed.Loud speaker can be made to hang on eminence and not easily drop by the sliding-off proof mechanism in linking up with and linking up with.Simultaneously, be slidably matched by guide pillar and centre pilot cover and can play good guide effect, thus the frictional force greatly reduced between magnetic conductive core column and magnetic conduction sleeve, power simultaneously needed for loudspeaker vibration is divided equally by multiple magnetic conductive core column, the proportional reduction of frictional force between single magnetic conductive core column and magnetic conduction sleeve, it also avoid the attenuation of fricative heat for the magnetic property of magnetic conductive core column thus.That is, the heat that sliding friction produces mainly concentrates on guide pillar, and divides equally again between magnetic conductive core column and magnetic conduction sleeve, and the frictional force therefore between magnetic conductive core column and magnetic conduction sleeve is less.
Described sliding-off proof mechanism comprises rotating shaft, the lateral wall of rotating shaft is provided with at least three equally distributed blades of the circumference along rotating shaft, one end and the rotating shaft of blade are fixed, the madial wall of hook is provided with the chute be slidably matched with the other end of blade, the open end width of chute is less than slot bottom width, the end that described blade stretches in chute forms the radial defining flange matched with the shape of cross section of chute, in the groove bottom of described chute, indent forms some grooves, groove is greater than the degree of depth of the other end away from straight-bar along the degree of depth of nearly straight-bar one end of length direction of chute, and be provided with a steel ball and back-moving spring all separately in each groove, one end and the steel ball of back-moving spring are fixed, the sidewall of the other end of back-moving spring and the less one end of depth of groove is fixed, the diameter m of described steel ball is greater than the minimum range d of top to groove bottom land of blade
1, be less than the ultimate range d of top to groove bottom land of blade
2.By the sliding-off proof mechanism of this concrete structure, operating personnel can being made all need not to climb when loud speaker being suspended from the loud speaker of eminence and eminence of taking, only relying on the forked stiff rod of band just can to hang or take.Its operating process is convenient and swift.
One end of described centre pilot cover is referred to the other end of cone removable connection by the first connecting plate, and one end and first connecting plate of centre pilot cover are fixed, and the other end of cone is connected with the first connecting plate is removable.Be convenient to only change cone after cone damages, reduce maintenance cost.
Be provided with the second connecting plate between first connecting plate and the other end of cone, the other end and second connecting plate of cone are fixed, bonding between the first connecting plate and the second connecting plate.Be convenient to dismounting and change.
