Application device

Abstract

The invention discloses an application device, and the application device comprises a plurality of elastic parts, wherein each elastic part comprises a first connecting part, a second connecting part and a deformation part located between the first connecting part and the second connecting part; the first connecting part and the second connecting part are respectively connected to different parts in the application device, the different parts can move relatively, or the different parts are relatively static; the deformation part is formed by extending the first end to the second end along the same direction or different directions in a straight line and / or curve manner; and each elastic component is formed by integrally punching a sheet-shaped structure. The elastic parts of the application device are all of an integrated punch forming structure, manufacturing is easy and convenient, the planeness and dimensional tolerance of the punch forming elastic parts are easier to control, and the product yield is high. And the elastic component occupies a small space, so that thinning of the product is facilitated. In addition, even under the condition that the vibration displacement of the vibration unit is large, the compliance of the elastic component is kept good, and enough displacement can be provided.

Description

technical field [0001] The invention relates to the field of electroacoustic technology, in particular to an application device. Background technique [0002] Application devices, such as loudspeakers, are important acoustic components in electronic equipment, which are transducers that convert electrical signals into acoustic signals. At present, with the continuous progress and innovation of technology, the structural design of traditional loudspeakers is also constantly seeking innovation and change. It not only needs to meet the development trend of thinning, but also pays more and more attention to performance optimization and simplification of process. and cost control. [0003] In the existing loudspeaker, a damper is fixedly arranged on the voice coil frame to prevent the voice coil from being polarized in a non-vibration direction during the vibration process, and the damper is usually in the shape of a sheet spring. However, the manufacture of the sheet-shaped sp...
