Integrated horizontal vibration machine and manufacturing method thereof

Abstract

The invention discloses an integrated horizontal vibration machine and a manufacturing method thereof. The integrated horizontal vibration machine belongs to a vibration generation or transmission device, and comprises a vibration part, a fixed shell of the vibration part and a frequency application part, wherein the vibration part consists of an annular permanent magnet, an annular balance weight, a plate spring and an annular auxiliary spring and is integrally formed by a plastic injection molding member; and the integrated vibration part and the fixed shell of the vibration part are combined into a whole by a secondary plastic injection molding member. The integrated horizontal vibration machine thus designed is manufactured in a plastic injection molding mode that a plurality of members are made into one member, so a large quantity of single products of certain specifications can be produced in a certain range by using conventionalized molds, and a certain range of resonant frequency for driving products can be maintained conveniently.

Description

technical field [0001] The invention relates to a vibration generation or transmission device, in particular to an integrated horizontal vibration machine for portable mobile terminals such as mobile phones and MP4s and a manufacturing method thereof. Background technique [0002] In communication devices of mobile terminals such as mobile phones and MP4s, vibration signals are often used. For example, mobile phones use vibration signals to prompt users to answer. Devices that generate vibration signals are collectively referred to as vibrating machines, and horizontal vibrating machines are one of the vibrating devices. The horizontal vibrating machine is composed of a vibrating part, a fixed shell of the vibrating part, a frequency applying part, etc. The vibrating machine relies on the synchronous vibration between various components to realize the transmission of vibration signals. In the past production methods, welding, riveting and other methods are usually used to c...

AI Technical Summary

Problems solved by technology

In the past production methods, welding, riveting and other methods are usually used to combine multiple metal components constituting the horizontal vibrator. This non-standard combination method will lead to a large error range of the characteristics of each component, which is difficult Used to make products that require a fine range of resonant frequencies required by the present invention
