Problems solved by technology

[0004] Usually, a piezoelectric vibrator includes a piezoelectric vibrator and a mass block connected to the piezoelectric vibrator to strengthen the vibration, and the piezoelectric vibrator includes a substrate that acts as a core vibration and piezoelectric plates arranged on both sides of the substrate. Usually, the mass The block is connected to the connecting part extended from the substrate or the piezoelectric sheet, and there will be a gap between the vibrator and the mass block. When the vibrator produces the inverse piezoelectric effect and drives the mass block to vibrate together, the connection point between the mass block and the connection part is small. , resulting in unbalanced force between the vibrator and the mass block, which in turn causes the vibration of the mass block to be unstable and unbalanced, greatly reducing the vibration performance of the piezoelectric vibrator

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] The piezoelectric vibrator 10 of the present invention is used in most electronic products to provide users with a stronger vibration prompt function.

[0021] Such as figure 1 and 2 Shown is a structural schematic diagram of a preferred embodiment of the piezoelectric vibrator of the present invention. The piezoelectric vibrator 10 mainly includes a vibrator 11 , a mass 12 connected to the vibrator 11 , and a reinforcing part 13 located between the vibrator 11 and the mass 12 and connected to both. Wherein, the vibrator 11 includes a substrate 110 and a piezoelectric sheet disposed on the substrate 110 .

[0022] together with reference image 3 and Figure 4 , the piezoelectric sheet includes a first piezoelectric sheet 101 disposed on one side of the substrate 110 and a second piezoelectric sheet 102 disposed on the other side of the subs...

Abstract

The invention relates to a piezoelectric vibrator, comprising a vibrator and a mass block connected with the vibrator, wherein the vibrator comprises a substrate and a piezoelectric chip on the substrate; and a reinforcement part is connected between the vibrator and the mass block and used for balancing the vibration of the mass block. The piezoelectric vibrator can balance the vibration of the mass block, thus the vibration of the piezoelectric vibrator is more stable and reliable.

Description

【Technical field】 [0001] The invention relates to a vibrator, in particular to a piezoelectric vibrator applicable to most portable electronic products. 【Background technique】 [0002] With the development of electronic technology, portable consumer electronic products are becoming more and more popular, such as mobile phones, handheld game consoles, navigation devices or handheld multimedia entertainment equipment, etc., generally use vibration motors for system feedback, such as mobile phone Incoming call prompts, information prompts, navigation prompts, vibration feedback of game consoles, etc. Such a wide range of applications requires high performance and long service life of the vibration motor. [0003] As a kind of vibrator, the piezoelectric vibrator is widely used due to its small number of components, small size and thinness. For example, the piezoelectric vibrator is widely used on mobile phones. People feel the dynamics of incoming calls or information prompts...
