Abstract
A loudspeaker vibrational resonant disc comprises a vibrational resonant disc, a suspension edge and a speaker frame, wherein the vibrational resonant disc is linked with the speaker frame through thesuspension edge, the suspension edge can provide elasticity and a space, so the vibrational resonant disc can evenly and stably vibrate and speak to a special direction. The speaker also comprises amagnetic loop system which is linked with the back of the speaker frame by a base, so the vibrating force vertical to the vibrational resonant disc can be available. The vibrational resonant disc is in a polygon shape, the suspension edge surrounds the periphery of the polygon-shaped vibrational resonant disc to form a polygon-shaped suspension edge which protrudes outward between the vibrationalresonant disc and the speaker frame; each corner of the suspension edge is provided with a protruding part protruding outward, in this way, the phenomenon that the polygon structure can lead that thecorner part is easy to fall off and is damaged due to the uneven stress can be avoided.
Description
Technical field:
The utility model relates to a kind of speaker diaphragm, be particularly related to a kind of outstanding limit of vibrating reed of polygon of loud speaker, see through the outwards outstanding structure in corner on this outstanding limit, distribute situation uneven and that the corner is damaged easily to improve the strength that the polygon vibration plate structure brought.
Background technology:
Traditional loud speaker mainly is made up of voice coil loudspeaker voice coil, basin frame, vibrating reed etc., and vibrating reed comprises that further an outstanding limit is linked in the periphery of vibrating reed, in order to connect this vibrating reed and basin frame.The vibrating reed back side connects voice coil loudspeaker voice coil, plays to connect and support the voice coil loudspeaker voice coil effect, and its tonequality to loud speaker plays material impact, and therefore outstanding limit and vibrating reed had not only needed certain stablizing constant elasticity but also need to go certain hot strength.
The cloth that existing vibrating reed is made into by cotton or staple fibre (staple fibre or blending separately) makes, in order to improve its intensity and enough elasticity to be arranged, need make the discoid wavy shaped configuration of the some ring bars of a surperficial tool, and with its impregnation phenolic resins, so complicate fabrication process, the manufacturing cost height.And the link that influences quality in the manufacture process too much influences the quality of product.Also owing to resin weather resisteant on the fiber is poor, through use after a while, elasticity can change, and therefore also can influence its quality.
In order to improve the hot strength of existing vibrating reed, the structure of vibrating reed some improvement have been done, for example: a kind of vibration plate structure that prevents surging, it mainly is to use the vibration plate structure in loudspeaker, be connected with symmetrically arranged reinforcing body in the vibrating reed body surface, and between vibrating reed body and reinforcing body, be combined with lead and be combined with corresponding engagement means and fix, and then can prevent that lead is when dismounting, vibrate for a long time or be subjected to improper the pullling of external force and come off, displacement, and vibrating reed body and reinforcing body are all elastic material institute interlacing and form, and the braiding lines that makes the braiding lines of vibrating reed body and reinforcing body to be the direction of about 45 degree or special angle mutually staggered, can increase the structural strength of its vibration resistance, to prevent that its vibrating reed body from producing protrusion of surface because of long-time vibration back or rugged situation produces.
Again for example: a kind of vibration plate structure that prevents undesired vibrations, principal character is to be covered with to possess flexible reinforcing chip on vibrating reed, it is less annular, bigger annular that this reinforcing chip can adopt various suitable forming materials, or the strip lamellar body of corresponding vibrating reed radius; The reinforcing chip of this different shape can be incorporated into the vibrating reed surface respectively or simultaneously, use the intensity that promotes vibrating reed, allow the stressed more average of vibrating reed all directions simultaneously, abnormal vibration take place to avoid vibrating reed.
More specifically, for the vibrating reed of square structure, because the oscillation intensity that four corners are subjected to is relatively greater than four oscillation intensitys that the limit is suffered, the loud speaker of this similar structure, in use for some time, four corners are owing to be subjected to relatively large stressed and peel off easily.Therefore some reinforcing chips are added in four corner portions located of the outstanding limit inner face of square vibrating reed, with special reinforcement corner portions located, because the relation of planform and the crisp especially weakness that falls.
Yet though above-mentioned these improvement can increase certain intensity, its complex structure is made also complexity, and performance can not be greatly improved simultaneously.Prior art, cover various reinforcing chips in the outstanding limit of vibrating reed inner face, though can strengthen its oscillation intensity, but also cause simultaneously outstanding limit inner face unsmooth of vibrating reed, particularly square vibrating reed causes the place of outstanding limit corner to be given a discount when up-down vibration easily, limitation and restriction the vibrating reed range of movement, and reduce the acoustical quality of this loud speaker integral body greatly.
The utility model content:
Main purpose of the present utility model is to provide a kind of vibrating reed of loud speaker, and the reinforced structure of this vibrating reed effectively promotes the durability of vibrating reed.
Main purpose of the present utility model is to provide a kind of vibrating reed of loud speaker, and this vibrating reed has a polygonal shape, comprises an outstanding limit, be linked in this polygonal vibrating reed around, be linked in the basin frame of a loud speaker with this outstanding limit for vibrating reed.Should a plurality of structures of outwards giving prominence to or caving inward be arranged outstanding limit, supply respectively in polygonal each corner, to improve the polygon vibrating reed, make each corner of vibrating reed peel off basin frame shortcoming because of relatively large vibration force easily with this structure because of structural relation.
Main purpose of the present utility model is to provide a kind of vibrating reed of loud speaker, and wherein the reinforced structure on the outstanding limit of this loud speaker has a level and smooth inner face, to keep certain tonequality.
