Description
Technical field
The utility model provides a kind of loadspeaker structure, especially the ultrathin loudspeaker of high power lower resonant frequency.
Background technology
Consult shown in Figure 1, be the loud speaker of commonly using, it mainly comprises a U iron (U Yoke full name " U type yoke ") 10, can be for being incorporated into support 11 bottoms, these U iron 10 central authorities are provided with a magnet 12 and a packing ring (Washer or title " washer ") 13, the outer rim of this packing ring 13 is provided with a voice coil loudspeaker voice coil (Voice Coil) 14, winding coil (Coil) 141 on this voice coil loudspeaker voice coil 14, and make and do not have the position of coil 141 on the voice coil loudspeaker voice coil 14 and form a voice coil loudspeaker voice coil pipe, and a damper (Damper) 15 can cementedly be arranged, and voice coil loudspeaker voice coil 14 tops are connected with vibrating disk (Cone) 16, and the ora terminalis of this vibrating disk 16 then is connected with outstanding limit (Edge) 17.
By above-mentioned composition, when the voice coil loudspeaker voice coil 14 of loud speaker shook, voice coil loudspeaker voice coil 14 beginnings can prevent voice coil loudspeaker voice coil 14 collision U iron 10 or magnet 12 and packing rings 13 by outstanding limit 17 and damper 15 when rock the side.Yet, the damper 15 of this kind loud speaker is arranged at voice coil loudspeaker voice coil 14 and does not have a position of coil 141, make the voice coil loudspeaker voice coil pipe of voice coil loudspeaker voice coil 14 must have equivalent length, otherwise fixedly damper 15, what therefore loud speaker was relative needs than the long ccontaining voice coil loudspeaker voice coil 14 of the degree of depth, and causes the height of loud speaker to descend; Moreover damper 15 is positioned at the top place of voice coil loudspeaker voice coil, makes that voice coil loudspeaker voice coil 14 centers of gravity are higher and rocks easily, causes the loudspeaker sound distortion.
Consult shown in Figure 2, the problem of rocking easily because known product has loud speaker height height, the disappearance that can't descend and voice coil loudspeaker voice coil center of gravity are higher, creator of the present utility model for this reason develops a loud speaker (as shown in Figure 2), damper 20 inner rings of this loud speaker are fixed on the coil 211 of voice coil loudspeaker voice coil 21, and damper 20 outer rings are connected to the end difference 222 of the accommodation space 221 of U iron 22, so this voice coil loudspeaker voice coil 21 can shorten length, make loud speaker can reduce height, and damper 20 positions also make voice coil loudspeaker voice coil 21 centers of gravity firm, be difficult for rocking, can reduce loudspeaker distortions.
Only, the creation that the utility model people is previous still has highly slightly high and still remains improvements.
Therefore, at the existing problem points of above-mentioned conventional construction, how to develop a kind of innovation structure that has more desirable practicality, the ardent hope of real consumer institute also is that relevant dealer must make great efforts target and the direction that research and development break through.
In view of this, the creator this in manufacturing development and the design experiences of being engaged in Related product for many years, at above-mentioned target, in detail after design and the scrupulous assessment, eventually the utility model of a true tool practicality.
Summary of the invention
The utility model purpose is, a kind of ultrathin loudspeaker of high power lower resonant frequency is provided, to overcome the defective of above-mentioned traditional structure, further reduce the loud speaker height and reach superthin structure, and more firm practical function.
The technical characterstic of dealing with problems: a kind of ultrathin loudspeaker of high power lower resonant frequency, it is characterized in that, include:
One support, the bead of support apical margin is provided with outstanding limit, and another lateral margin of outstanding limit then is connected with a vibrating disk, and another ora terminalis of this vibrating disk then differs from overhang with voice coil loudspeaker voice coil and is connected, and this vibrating disk is positioned at the place, top position of voice coil loudspeaker voice coil, is stamped a dust cap;
One U iron, the bottom edge of this U iron combines with frame bottom, this U iron end face is concaved with an alcove, the alcove periphery is provided with the short slot more than two, these U iron central authorities are provided with a magnet, and magnet be provided with a packing ring;
One voice coil loudspeaker voice coil, it has a hollow bulb, and be sheathed on the magnet outer rim, and be arranged with coil on the lower end of this voice coil loudspeaker voice coil, on coil, be coated with high temperature resistant viscose, and cemented a bridge formation arranged, several support arms of this bridge formation are passed to the outside by the short slot of U iron again, and a damper is located at U iron periphery, the inner ring of this damper is solidly connected on the bridge formation, and the outer ring of damper then is solidly connected on the single order shape bead of support.
Wherein, this internal stent is formed with and is gradually narrow stair-stepping accommodation space.
Wherein, this bridge formation binds connection mutually with voice coil loudspeaker voice coil under the coil.
Wherein, this bridge formation that is piercing in short slot props up arm portion, is disc-shape.
In view of the above, U iron is established short slot, and moves to outside the U iron outside the damper (Damper) by building bridge, and the loud speaker whole height can be recompressed, and reaches ultra-thin high effect lower resonant frequency loud speaker effect.
The effect of contrast prior art:
One, the voice coil loudspeaker voice coil center of gravity height of prior art, so easily rock, and the voice coil loudspeaker voice coil length requirement is long, and the loud speaker height can't be reduced, and voice coil loudspeaker voice coil center of gravity of the present utility model is low and be difficult for rocking, and voice coil loudspeaker voice coil length is short, and the loud speaker height can effectively reduce.
Though two, the voice coil loudspeaker voice coil of prior art can reduce, the reduction of height is still limited, and the utility model mat short slot shifts out damper outside the U iron, so the loud speaker height can significantly reduce.
The technology that relevant the utility model adopted, means and effect thereof after lifting a preferred embodiment now and cooperating graphic being described in more detail in, are believed the above-mentioned purpose of the utility model, structure and feature, when can by one deeply and concrete understanding.
