Flapping device used for minitype loudspeaker device

Abstract

The invention discloses a flapping device used for a minitype loudspeaker device, wherein the flapping device is provided with an improved structure. The flapping device comprises a vibrating disk part, a mechanical structure reinforcing rib part and through hole structures, and is characterized in that the vibrating disk part is of a planar structure, the mechanical structure reinforcing rib part is arranged on a vibrating disk according to the design demands, at the same time, and a plurality of through hole structures are distributed in the vibrating disk and the mechanical structure reinforcing rib part to form the flapping device together. The flapping device has at least the advantages that compared with a traditional flapping device, the flapping device makes an improvement on the design of a mechanical structure reinforcing rib, and a mechanical shock resistance property and vibration stability of the flapping device are greatly improved. Compared with a traditional design, the design of the flapping device is strong in manufacturability and low in cost. In addition, the flapping device can meet different frequency response requirements of various minitype loudspeaker devices by adjusting of the shapes of the vibrating disk, the shapes and the number of mechanical structure ribs and the through holes, and an application range is very wide.

Description

technical field [0001] The invention relates to a vibration conduction and energy conversion device, in particular to a flapping device used in a micro speaker device, and belongs to the fields of electroacoustics and micro mechanics. Background technique [0002] At present, the fluttering devices used for micro-speaker devices on the market generally adopt a flat plate structure. The manufacturing and processing of this kind of fluttering device is relatively simple, but its mechanical rigidity is poor, and the mechanical resonance frequency is low; The frequency response effect must make its mass as light as possible, so the selection of materials is greatly restricted. In short, the existing flapping devices generally have insufficient structural rigidity, poor mechanical shock resistance, and poor stability under high-frequency vibrations; furthermore, the existing flapping devices have a narrow range of material selection. The requirements are more stringent, which li...

In short, the existing flapping devices generally have insufficient structural rigidity, poor mechanical shock resistance, and poor stability under high-frequency vibrations; furthermore, the existing flapping devices have a narrow range of material selection. The requirements are more stringent, which limits its scope of use and weakens its competitive advantage
