Problems solved by technology

During application, the quality block is easy to fall off from the piezoelectric sheet, which affects the vibration stability of the piezoelectric vibrator
In addition, when the piezoelectric sheet flexes and vibrates, it will collide and interfere with the mass block, which will affect the vibration effect of the piezoelectric vibrator

Abstract

The invention discloses a piezoelectric vibrator. The piezoelectric vibrator comprises a substrate, piezoelectric sheets, a self-extending supporting sheet and a mass block, wherein the piezoelectric sheets are placed on the two sides of the substrate; and the mass block is placed on the supporting sheet and has a certain distance with the piezoelectric sheets. The piezoelectric vibrator has high stability.

Description

【Technical field】 [0001] The present invention relates to a piezoelectric vibrator. 【Background technique】 [0002] Electronic device manufacturers, especially portable electronic device manufacturers, are always improving the user experience. Traditional devices use sight and sound to provide feedback to users, such as video playback and audio playback. In some devices, motion feedback (such as active force and resistance feedback) and tactile feedback (such as vibration, thermal energy) can provide users with a more intense use experience. Specifically, the tactile effects of vibration effects and vibration haptics provide real feedback to create sensory experiences in simulated or virtual environments. For example, the explosion effect in a game console will cause a strong vibration of the user's equipment, while water droplets will cause small vibrations. The vibrations, the need for this experience, are constantly being heated. [0003] Tactile feedback is being inco...
