Problems solved by technology

But this doesn't prevent the region above the resonance frequency from producing distortion
Although these efforts can effectively improve the characteristics, most of them are at the cost of sacrificing process simplicity and increasing cost

Embodiment Construction

[0020] This embodiment takes the speaker diaphragm as an example, from figure 1 It can be seen that the present invention includes a vibration damping membrane 1, a damping layer 2 and a vibration membrane 3. The vibration membrane 3 is located in the lower layer, and the damping layer 2 is located between the vibration damping membrane 1 and the vibration membrane 3 and connects the vibration damping membrane 1 and The diaphragms 3 are bonded together, and the damping diaphragm 1 is a sun flower-shaped star. The damping layer 2 is a damping layer with a flexible adhesive layer structure, and the diaphragm 3 is a cone-shaped structure.

[0021] For the sun flower-shaped ten-pointed star-shaped vibration-absorbing layer 1 structure, the zigzag shape of the edge of the vibration-absorbing layer 1 can not only disperse the energy like a coastal breakwater, and form a uniform vibration distribution, but also greatly weaken the overall diaphragm The sudden change in intensity forms a...

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.

Description

Technical field [0001] The invention relates to a vibration absorbing device, in particular to a vibration absorbing device used in audio equipment and a vibrating body with special requirements for acoustics. Background technique [0002] Ordinary traditional diaphragm is made of single-layer paper, plastic and other materials, and has its natural frequency. The diaphragm is not a completely rigid body. On the one hand, when it moves, it will deform like a touched water surface. The wave propagates from the center to the periphery and the front end. When it encounters the edge, the wave will be reflected back like a ripple, thereby interfering with other waveforms. The diaphragm in free space presents an almost ideal piston motion below the resonance frequency, but when it is close to or higher than the natural resonance frequency, it will deform itself, which will cause harmonic distortion and deteriorate sound quality. On the other hand, since there is mostly a relatively clo...
