Abstract
This invention relates to a part of audio visual device to restrain the peak valley for the resonance of loudspeaker, earphone, and microphone and improve the replay effect, which is exact a bearing folded ring with opposite wave on one circular. The product comprises curved bearing ring composed of concave and convex bearing inner rings on same circular belonged to phase-compensation folded ring of circular, ellipse, square or other shapes, outer ring and inner ring; wherein, the interior and exterior track of curved bearing ring connects to separately the outer and inner ring. The invention can make the voice of the bearing folded ring minimum and improves opposite devices' replay performance.
Description
Technical field
The present invention relates to parts of audio-visual apparatus, specifically is to suppress devices such as loud speaker, earphone, microphone to cause the peak valley that produces because of shaking altogether, makes the improved a kind of support folded ring that mutually reverse-wave is arranged in same perimeter line of replaying effect.
Background technology
Audio-visual apparatus has entered people's sphere of life, and loud speaker, earphone, microphone etc. are arranged in these audio-visual apparatuss.The vibrating diaphragm of these device sounding all is connected with the frame of device by support folded ring, or the pronunciation part of vibration is connected with the frame of device by the voice coil loudspeaker voice coil centering bullet ripple that support folded ring constitutes.One side that support folded ring is connected to sound basin or pronunciation part can vibrate with the vibration of sound basin or pronunciation part, the another side that support folded ring is connected to frame then is in static, usually wish that support folded ring has big axial stroke and little radial stroke, therefore support folded ring needs the development size of bigger radial direction, forms the ripple of concavity or convex.Existing support folded ring all adopts the concavity single on same perimeter line or the corrugated design of convex, because different frequency has different wavelength, the response time of transfer of vibration speed and support folded ring does not reach in full accord, therefore causes the inconsistent of the direction of motion, promptly produces phase difference.If the vibration that sound wave that sound wave that a certain frequency lower support ring produces and sound basin produce or pronunciation part produce is synchronous, will produce the peak because of mutual superposition, if the vibration that sound wave that sound wave that support folded ring produces and sound basin produce or pronunciation part produce is an antiphase, will produce paddy because of cancelling out each other.Problems such as existing loud speaker, earphone, microphone bring audio distortions owing to there not being to use the support folded ring of doing the phase compensation design on same perimeter line to have influence on the glacing flatness of amplitude frequency curve, and available frequency domain is not wide.
Notification number CN2513313Y, title " adopting the coil-moving speaker of composite type vibrating diaphragm ", in order to improve conversion efficiency effectively, increase the playback frequency bandwidth, reduce distortion, good film edge in loud speaker has ring, also has ring at little vibrating diaphragm edge, owing to increased little vibrating diaphragm and had ring and pronunciation part independently, improved the operating efficiency of vibrating diaphragm when various frequency, increased power, and minimizing distortion, but it needs two rings, and each ring is the corrugated design of single convex on same perimeter line, or the corrugated design of single concavity.
Notification number CN2452226Y, title " regular polygon loudspeaker cone and basin frame ", in order to improve tonequality, adopt the ring of regular polygon, make sound basin shape also change regular polygon into, because the sound pressure level of loud speaker institute radiation is to be directly proportional with the swept area of sound basin, so when input power was identical, regular polygon sound basin was bigger than the sound pressure level of the conical sound basin institute radiation of the inscribed circle of same diameter.Though this method volume is improved, the sound basin will change shape, makes other parts that match also will change design, and ring is single convex ripple on same perimeter line, or the concavity ripple.
Notification number CN2314539Y, title " a kind of loud speaker " is that to use multilayer ring, shape between casing and cone be that some dish-shaped sheets are piled up, bonding forming, or forms with bellows.In order to improve the deformability of ring, the ring number of plies should be more than or equal to three, and as five layers of ring, and ring also is single shape on same perimeter line.
Summary of the invention
The object of the invention provides a kind of support folded ring of mutually reverse-wave on same perimeter line with effect of phase compensation, makes the amplitude frequency curve of electro-acoustic elements such as loud speaker, earphone, microphone more straight, and distortion reduces.
The present invention seeks to such realization: the improved support folded ring that mutually reverse-wave is arranged in same perimeter line of replaying effect that makes electro-acoustic elements such as loud speaker, earphone, microphone.This support folded ring is made up of slippery supporting ring, outer shroud, interior ring, the inner ring of slippery supporting ring is connected with interior ring, the outer ring of slippery supporting ring is connected with outer shroud, it is characterized in that described slippery supporting ring is made of jointly concavity support folded ring and convex support folded ring, the position is the phase compensation ring all in same perimeter line.The perimeter line of the support folded ring of this mutually reverse-wave can need be made the shape of circle, ellipse, polygon, horn, spiral according to device.Described perimeter line has one group.The quantitative proportion of described concavity support folded ring and convex support folded ring was designed to 1: 2,2: 1,2: 3,3: 2,3: 4.The concavity support folded ring of the mutually reverse-wave of described slippery supporting ring and convex support folded ring can be arc, semicircle, dihedral, polygon.
Beneficial effect of the present invention: owing to be positioned at direction is opposite on the same perimeter line concave, convex shape support folded ring when vibration takes place, the pronunciation phase place of negative area is opposite with the pronunciation phase place of bossing, the pronunciation that reaches whole support folded ring is reduced to minimum, total pronunciation contribution reduces to minimum to support folded ring to loud speaker, earphone, microphone etc., has improved the playback quality of devices such as loud speaker, earphone, microphone.
