Abstract

The invention relates to a spring plate and a multifunctional acoustic generator with the same. The spring plate comprises a peripheral edge and inner rings. The inner rings extend from the peripheral edge to the inner side of the spring plate and comprise spiral deformation portions and fixing portions, the spiral deformation portions extend from the peripheral edge, the fixing portions are positioned at the tail ends of the deformation portions, and the inner rings can be fixed onto other components via the fixing portions. The spring plate and the multifunctional acoustic generator with the same have the advantages that the multifunctional acoustic generator with the spring plate can vibrate stably and is good in reliability.

Description

【Technical field】 [0001] The invention relates to the field of communication with directivity function, in particular to a multifunctional sound generator and its usage method. 【Background technique】 [0002] With the rapid development of wireless communication, there are more and more mobile phones in the world. People's requirements for mobile phones are not limited to basic calls, but also put forward more requirements for entertainment functions of mobile phones. Especially with the advent of the 3G era, mobile multimedia technology has also developed. Many mobile phones have multiple entertainment functions, such as video playback, digital photography, games, and GPS navigation. Therefore, the effect of the loudspeaker in the mobile phone is more and more important, if the sound quality of the sound played by the loudspeaker in the mobile phone is not good or the sound quality is unstable, it will directly affect people's entertainment experience. [0003] Usually, a s...
