Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0028] exist figure 1 and figure 2 Among them, the linear driving device 10 belongs to the lens driving device described as an example. The linear actuator is used in auto-focus miniature cameras, which in turn are used in electronic devices such as mobile phones and smartphones. The linear drive device 10 has a housing 12 having a cubic shape. The housing 12 is provided with an imaging lens 14 , an imaging lens 16 , a zoom lens 18 and a focus lens 20 .

[0029] The imaging lens 14 is fixed a...

Abstract

The invention provides a piezoelectric actuator, a linear drive device and electronic equipment. The piezoelectric actuator is equipped with a vibration component and a drive shaft. The vibration component has a flat piezoelectric element and a piezoelectric element embedded in the piezoelectric element. The electrode plate is fixed with the mutual plate surface; the drive shaft is fixed in the vibrating part; the vibrating part has edges connecting several vertices on its periphery, and the electrode plate has an electrical connection part, from The sides of the vibrating member start to take on a convex shape. Linear drives with moving parts and piezoelectric actuators; electronics with housing and linear drives. The present invention can realize the miniaturization of devices and equipment.

Description

technical field [0001] The invention relates to piezoelectric actuators, linear drives and electronics. Background technique [0002] A bimorph piezoelectric actuator is shown in the patent document (US 2009 / 0159720 A1). The bimorph type piezoelectric actuator has a vibrating part between the electrode plates in the two piezoelectric elements. This piezoelectric actuator electrifies any piezoelectric element or two piezoelectric elements through the electrode plate, deforming the vibrating part into a bowl shape and outputting a signal. [0003] However, the vibrating member shown in the patent document is circular, and the electrical connection part provided on the electrode plate is composed of a circular vibrating member, which is in the shape of a protrusion. Therefore, the external shape is enlarged as a whole by the electrically connected portion. If it is applied to a linear drive device mainly a lens drive device, there is an obstacle in terms of device miniaturiz...
