Abstract
The invention relates to a vibrating-body vibration eliminating device, which is applied to sound equipments and has special acoustic requirements. The vibrating-body vibration eliminating device comprises a vibration eliminating diaphragm, a damping layer and a vibrating body, wherein the vibrating body is located at the lower layer and the damping layer is positioned between the vibration eliminating diaphragm and the vibrating body and bonds the vibration eliminating diaphragm and the vibrating body together. The vibration eliminating diaphragm has a sunflower-like polygonal star shape. The damping layer has a soft bonding layer structure. By adopting the vibration eliminating diaphragm having the sunflower-like polygonal star shape and the sandwich structure of the damping layer with the soft bonding layer structure, the vibrating-body vibration eliminating device effectively solves the problems of deformation and echo interference which may be caused during the sound transmission. The vibrating-body vibration eliminating device has three characteristics of enhancing, scattering and damping and substantially increases the strength and the internal friction when weight is slightly increased. In addition, the vibrating-body vibration eliminating device can effectively eliminate adverse resonance when applied to electroacoustic products. Furthermore, the vibrating-body vibration eliminating device is simple and practical in structure and low in cost.

Technical field
The present invention relates to a kind of vibration damping device, particularly a kind of vibrating body vibration damping device that is applied to stereo set and acoustics is had specific (special) requirements.
Background technology
Common traditional vibrating diaphragm is to process with materials such as single-part stationery, plastic cement, and its natural frequency is all arranged, and vibrating diaphragm is not a rigid body completely, and during its motion, itself can produce deformation as the water surface of shake-up on the one hand.Waveform along by the center to around with front end propagation, when running into the edge, ripple also can equally be reflected by ripples, thereby interferes each other with other waveforms.Vibrating diaphragm in the free space presents the piston motion of approximate ideal below resonance frequency, but near and be higher than the distortion that can produce self more than the natural reonant frequency and can cause harmonic distortion, sound quality deterioration.On the other hand, because mostly there is the space of a relative closure behind in vibrating diaphragm, in the time of when motion, can compressing the air in this space, can produce bigger buffer brake, cause the vibrating diaphragm distortion, the piston characteristic is destroyed, and low frequency output descends.
Though can partly improve above problem through increasing vibrating diaphragm thickness, the thing followed is the sacrifice of frequency range and the decline of efficient (because of weight increases).Therefore, the application new material that people do one's utmost improves the vibrating diaphragm characteristic, improves the Young's modulus of material, and the phase obtains higher resonance frequency, widens piston region.But this can not stop the zone that is higher than resonance frequency to produce distortion.Though these effort can improve characteristic effectively, be cost mostly to sacrifice the easy increase cost of technology.
Summary of the invention
The present invention is to the deficiency of prior art, and a kind of vibrating body vibration damping device that is applied to stereo set and acoustics is had specific (special) requirements is provided.
The present invention realizes through following technical scheme:
A kind of vibrating body vibration damping device; Comprise weakening film, damping layer and vibrating body; It is characterized in that: said vibrating body is positioned at lower floor, and damping layer bonds together between weakening film and vibrating body and weakening film and vibrating body, and said weakening film is flower-shaped polygonal star-like of the sun.
