Abstract
The invention discloses a composite diaphragm horn without a cone. The composite diaphragm horn comprises magnetic steel, a coil support and a horn support. The composite diaphragm horn further comprises a composite diaphragm and a conductive support arranged on the coil support for connecting the coil support and the composite diaphragm. The composite diaphragm is arranged on the end portion of the horn support and comprises a high-molecular membrane, a sound absorbing material and a sheet metal, wherein the sheet metal is coaxially glued to the surface of the high-molecular membrane, the sound absorbing material encloses the sheet metal and is glued to the surface of the high-molecular membrane, and the height of the conductive support between the coil support and the composite diaphragm. The composite diaphragm horn overcomes the amplification distortion caused by cone-horn structure. The planar structure of the composite diaphragm horn makes the sound audible scope wider. A die of a conventional cone is high in cost, and the composite diaphragm can be produced easily without an expensive die and can be made into various shapes.
Description
Technical field
The utility model relates to the loudspeaker field, particularly relates to a kind of without cone basin composite diaphragm loudspeaker.
Background technology
Traditional cone benzvalene form loudspeaker are comprised of annular magnetic steel, washer, basin frame, cone basin and coil, a cylinder type coil is arranged in the middle of ringshaped magnet, the coil front end is directly fixedly on cone or vibrating diaphragm, in coil, pass through tone currents, coil cutting magnetic line, coil will move forward and backward and affect the cone sounding.Traditional loudspeaker easily produce the hum interference of 60Hz and 120Hz by the DC pulse of solenoid; And the current strength of solenoid changes with audio signal, cause new destabilizing factor.All the time, all in the industry by the material of ceaselessly optimizing the cone basin, to pursue the voice quality of loudspeaker, to such an extent as to develop static loudspeaker afterwards, it is to be overcome that but the static loudspeaker still have some problems: the volume deficiency, impedance load makes some enlarger forbidding, the diffusivity deficiency, load power is also limited, again to the mixed cone basin bass horn developed later, allow loudspeaker tonequality and cost had significantly and to have improved, also more by the consumer, accepted, but the structure of the audition scope of loudspeaker and frequency response and loudspeaker itself still has many areas for improvement.
The utility model content
For optimizing the structure of existing cone benzvalene form loudspeaker, the frequency response of expansion loudspeaker, the audition scope of loudspeaker, propose a kind of loudspeaker without the cone basin, replaces traditional cone basin with composite diaphragm.
The utility model adopts following technical scheme:
A kind of without cone basin composite diaphragm loudspeaker, comprise magnet steel, washer, coil brace and horn bracket, also comprise composite diaphragm and conduction support, and described conduction support is arranged on coil brace, for connecting coil support and composite diaphragm, described composite diaphragm is arranged on the end of horn bracket.
In technique scheme, described composite diaphragm comprises polymeric membrane, sound-absorbing material and sheet metal, and described sheet metal concentric is pasted on the polymeric membrane surface, and described sound-absorbing material is pasted the polymeric membrane surface around sheet metal.
In technique scheme, described sound-absorbing material is pasted on the polymeric membrane surface around sheet metal.
In technique scheme, the height of the conduction support between described coil brace and composite diaphragm is adjustable.
The utility model has the advantage of: overcome the distortion that amplifies caused on cone basin horn structure, due to cone basin loudspeaker compressed air when amplifying, the shape of cone basin inevitably causes distortion.Composite diaphragm is that a plane does not have distortion when vibration amplifies or distortion is less.Traditional cone basin due to material more thick and heavy under inertia-responsive impact the frequency response of loudspeaker be restricted and composite diaphragm material and the structure very frivolous Hz-KHz that can expand greatly loudspeaker all, (actual formula listen 8 cun horn frequency upper ends of same bore roughly to expand to 800-900 hertz of left and right, lower end roughly expand to 80-60 hertz of left and right).Cone basin loudspeaker, because the directive property of cone basin only just has good hearing effect in very little scope, leave this range effect and just have a greatly reduced quality.The planar structure of composite diaphragm loudspeaker can accomplish that the scope of hearing effect is very wide.Traditional cone basin need to spend very high mould expense on manufacturing cost, and composite diaphragm can be easy to make, and does not need expensive mould.And can be made into various shapes.
The accompanying drawing explanation
The utility model will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of composite diaphragm in the utility model;
Wherein: the 1st, magnet steel 2 is that coil brace 3 is that conduction support 4 is composite diaphragms
The 41st, frame 42 is that polymeric membrane 43 is that sheet metal 44 is that sound-absorbing material 5 is horn brackets.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, nothing cone basin composite diaphragm loudspeaker described in the utility model comprise magnet steel 1, coil brace 2 and horn bracket 5, these three parts are not do change according to traditional horn structure, composite diaphragm 4 is to have replaced in traditional loudspeaker to bore basin, be arranged on the end of horn bracket 5, in order to allow electromagnetic vibration kinetic energy effectively be delivered on composite diaphragm 4, between composite diaphragm 4 and coil brace 2, be provided with a conduction support 3, the two ends of conduction support 3 are connected on coil brace 2 and composite diaphragm 4; In order to guarantee effective transmission of electric and magnetic oscillation, according to the actual needs of loudspeaker, can reduce the height of conduction support, in the situation that process conditions meet, even can cancel conduction support 3, allow composite diaphragm 4 directly with coil brace 2, contact.
And composite diaphragm 4 comprises a polymeric membrane 42, in the center of polymeric membrane 42, paste a sheet metal 43, sheet metal 43 and polymeric membrane 42 concentrics, also need to paste a circle sound-absorbing material 44 on the surface of polymeric membrane 42, sound-absorbing material 44 be centered around sheet metal 43 around; Finally polymeric membrane is clamped with frame 41, the surface of polymeric membrane 42 is to need smoothly, and fold can not be arranged.The composite diaphragm that will combine after group is stuck in the end of horn bracket 5.
Disclosed all features in this specification, except mutually exclusive feature, all can combine by any way.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
Claims (4)
