The acoustical devices such as loud speaker are as voice playing device, very large on the impact of the power amplifier performance of above-mentioned mobile electronic device, and vibrating diaphragm is as the core sounding component of the acoustical devices such as loud speaker, also just improves the requirement of its acoustical behavior thereupon.The vibrating diaphragm of correlation technique is formed by the compacting of some hot pressing moulding materials, in actual applications, the vibrating diaphragm of correlation technique cannot the vibrational state of Real-time Feedback vibrating diaphragm, cannot revise vibration of membrane of shaking according to the vibrational state of vibrating diaphragm in real time and regulate, thus guarantee that the maximization of intelligent power output amplification sound quality embodies.
Therefore, be necessary to improve the vibrating diaphragm of correlation technique, to avoid above-mentioned defect in fact.
[utility model content]
The purpose of this utility model be to provide a kind of can Real-time Feedback vibrating diaphragm vibrational state vibrating diaphragm and apply the loud speaker of described vibrating diaphragm.
The purpose of this utility model is achieved in that
The utility model provides a kind of vibrating diaphragm, by there is the piezoelectricity coating layer of the vibrational state of vibrating diaphragm described in signal of telecommunication Real-time Feedback that direct piezoelectric effect exports when described vibrating diaphragm comprises the vibrating diaphragm body layer of mutual stacked setting and described diaphragm oscillations.
Preferably, described piezoelectricity coating layer is polyvinylidene fluoride layer.
Preferably, described piezoelectricity coating layer is evenly coated in described vibrating diaphragm body layer by spraying method.
Meanwhile, the utility model additionally provides a kind of loud speaker applying above-mentioned arbitrary vibrating diaphragm.
Compared to correlation technique, the vibrating diaphragm that the utility model provides has following beneficial effect:
One, the vibrational state of signal of telecommunication Real-time Feedback vibrating diaphragm that exported by piezoelectricity coating layer generation direct piezoelectric effect when vibration of the vibrating diaphragm that provides of the utility model, and then follow-uply can revise vibration of membrane of shaking according to the vibrational state of vibrating diaphragm in real time and regulate, thus guarantee that the maximization of intelligent power output amplification sound quality embodies.
Two, piezoelectricity coat is polyvinylidene fluoride layer, and its material is pliable and tough, the advantage of low-density, Low ESR and high-tension electricity voltage constant makes piezoelectricity coat have good piezoelectricity, and piezoelectric effect is obvious, is quick on the draw, can better feeds back the vibrational state of vibrating diaphragm.
Three, piezoelectricity coat adopts spraying method preparation, and can ensure that coating evenly, effect is more excellent.
