Description
Technical field
The present invention relates to the technical field of electro-acoustic transducer device, the Suspensible that specifically a kind of both sides are pronounced is raised one's voice
Device.
Background technology
Coil-moving speaker is also known as dynamic speaker.Its operation principle is according to Faraday's law, works as current－carrying conductor
When passing through magnetic field, an electric power can be subject to, direction, which meets, not carrys out bright left hand rule, and power is hung down mutually with electric current, magnetic direction
Directly, stress size is directly proportional to electric current, conductor length, magnetic flux density.When voice coil inputs alternation tone currents, voice coil is subject to one
A alternation motive force generates alternate motion, drives cone vibration, promotes air repeatedly and sounding.And subtract during voice coil vibrations
The deviation of small voice coil radially is to ensure the important indicator of sounding tonequality.
And in the dynamic speaker of the prior art, voice coil is often contained directly in the centre bore of drive magnet,
Or voice coil is placed on outside a columnar conducting magnet core, and in order to reduce the frictional force between voice coil and magnet, therefore, voice coil
Larger glade plane space is necessarily left between magnet.This result in deviation of the voice coil during vibration sounding radially compared with
Greatly, so as to causing the misalignment of sound.
The content of the invention
The technical problems to be solved by the invention are：A kind of Suspensible loud speaker of both sides pronunciation is provided, voice coil shakes
The deviation of voice coil radially is small in dynamic voiced process, so that sounding tonequality is preferable, while the broad covered area of bilateral pronunciation, pass through
Hook is convenient for being arranged at eminence.
The technical solution used in the present invention is：A kind of Suspensible loud speaker of both sides pronunciation is provided, it includes substrate,
Two frame of substrate both sides are symmetrically set in, a sound generating mechanism is each provided in the frame of each side, substrate is equipped with arc-shaped
Hook, the lower end of hook is equipped with sliding-off proof mechanism, the sound generating mechanism includes by a straight-bar and substrate connection in hook
Cone, magnetic conductive board, drive magnet and the Voice coil assemblies for driving cone vibration, the drive magnet are clamped in substrate and lead
Between magnetic sheet, the osculum end of magnetic conductive board and the nearly substrate of frame is fixed, and cone is set up in frame, and the outer rim and basin of cone one end
The big opening end of frame is fixed, and the Voice coil assemblies include centre pilot set, at least two magnetic conductive core columns and are wound in each magnetic conduction core
Voice coil on column lateral wall, drive magnet are equipped with the storage tank of accommodating Voice coil assemblies, and storage tank is interior along the axis position of storage tank
Put and be fixed with a guide post, centre pilot set is slidably fitted on guide post, and centre pilot set one end by the first connecting plate with
The removable connection of the other end of cone, whole magnetic conductive core columns are uniformly distributed along the circumferential direction of centre pilot set axis, magnetic conductive core column
One end fixed with the first connecting plate, the magnetic conduction sleeve being slidably matched with the magnetic conductive core column with voice coil is equipped in storage tank, is led
One end of magnetic sleeve is fixed with substrate.By the sliding-off proof mechanism in hook and hook loud speaker can be made to hang on eminence and not
Easily drop.Meanwhile be slidably matched by guide post and centre pilot set and can play good guiding role, so as to greatly reduce
Frictional force between magnetic conductive core column and magnetic conduction sleeve, while the power needed for loudspeaker vibration is divided equally by multiple magnetic conductive core columns, it is single
Thus the proportional reduction of frictional force between magnetic conductive core column and magnetic conduction sleeve also avoids the heat of friction generation for magnetic conduction core
The attenuation of the magnetic property of column.That is, the heat that sliding friction generates is concentrated mainly on guide post, and magnetic conductive core column and magnetic conduction
Divided equally again between sleeve, therefore the frictional force between magnetic conductive core column and magnetic conduction sleeve is smaller.
The sliding-off proof mechanism includes shaft, and the lateral wall of shaft is equipped at least three and uniformly divides along the circumferential of shaft
The blade of cloth, one end and the shaft of blade are fixed, and the madial wall of hook is equipped with the sliding slot being slidably matched with the other end of blade,
The open end width of sliding slot is less than slot bottom width, and the blade stretches into the formation of the end in sliding slot and the cross-sectional shape phase of sliding slot
The radial direction defining flange of cooperation is recessed several grooves in the groove bottom of the sliding slot, and groove is near along the length direction of sliding slot
The depth of straight-bar one end is more than the depth of the other end away from straight-bar, and a steel ball is each provided in each groove and resets bullet
Spring, one end and the steel ball of resetting spring are fixed, and the other end and the side wall of the smaller one end of depth of groove of resetting spring are fixed, described
The diameter m of steel ball is more than the top of blade to the minimum range d of groove slot bottom1, less than blade top to groove slot bottom most
Distance d greatly2.By the sliding-off proof mechanism of this concrete structure, can make operating personnel by loud speaker hang supreme place and
Climbing is not had to during the loud speaker for eminence of taking, relying solely on can hang or take with forked stiff rod.It is operated
Process is convenient and efficient.
One end of the centre pilot set refers to that center is led by the removable connection of the other end of the first connecting plate and cone
It is fixed to one end of set and the first connecting plate, the other end of cone and the removable connection of the first connecting plate.After being damaged convenient for cone
Cone is only replaced, reduces maintenance cost.
The second connecting plate is equipped between first connecting plate and the other end of cone, the other end of cone and the second connecting plate are consolidated
It is fixed, it is bonded between the first connecting plate and the second connecting plate.Replacement easy to disassemble.
The magnetic conductive core column is four.
It is connected between first connecting plate and the osculum end of frame by ring, and the first connecting plate and ring seal frame
The opening at osculum end.
After more than structure, a kind of Suspensible loud speaker of both sides of the invention pronunciation has compared with prior art
Advantages below：First, hook can make the loud speaker of the present invention hang on eminence, and can make to be placed in height by sliding-off proof mechanism
The loud speaker at place is not easy to drop when being subject to wind, and during the loud speaker for eminence of taking, it is only necessary to divided using carrying
The hard straight-bar of fork jacks up loud speaker and can remove naturally, is climbed without operating personnel, and placement process is simple and easy, secondly, symmetrically
Scope that the bilateral sound generating mechanism of setting can cover its sound is more wide, audio is good, secondly, passes through guide post and centre pilot
Set, which is slidably matched, can make the direction of motion verticality of voice coil drive cone good, therefore tonequality is good, finally, passes through guide post and center
The guiding role of guide sleeve, therefore reduce the frictional force between magnetic conductive core column and magnetic conduction sleeve, therefore the heat that its friction generates
Amount is reduced, and reduces magnetic attenuation of the frictional heat for magnetic conductive core column, while the internal temperature of reduction similarly avoids pair
In the magnetic attenuation of drive magnet, the service life of magnetic conductive core column and drive magnet is extended.
