Embodiment Construction

[0034] The present invention provides a single loudspeaker structure, which solves the problems of the prior art when the sound pressure power is increased, the loudspeaker structure and drive circuit are too complicated, the metal thin film electrode in the diaphragm structure is affected by the oxidation of the sound source signal input, and the product application design is diversified. question. The loudspeaker unit of the present invention has a simple structure, can be matched with existing technologies and processes, and is actually suitable for mass production.

[0035] The present invention proposes a loudspeaker structure, using the charge characteristics and electrostatic force effect inside the electret (Electret) material, when the electret diaphragm is stimulated by an external voltage, the surface of the diaphragm will be deformed, and then the vibration around the diaphragm will be driven. Air creates sound. According to the electrostatic force formula and ene...

Abstract

Proposed is a speaker in the monomer structure, including a single electret diaphragm structure, a single metallic electrode with a plurality of openings and a frame support. In an embodiment, the electret diaphragm structure is composed by stacking an electret diaphragm layer, a super thin metal film electrode and an insulating layer, wherein, the super thin metal film electrode is located between the electret diaphragm layer and the insulating layer. In another embodiment, the electret diaphragm structure is composed of an electret diaphragm layer and a conductive electrode layer with oxidation conductive material. The frame support is located between the electret diaphragm structure and the metallic electrode, forming a space for vibrating as an electret diaphragm structure, to producesound.

Description

technical field [0001] The present invention relates to the structure of a loudspeaker unit, and in particular to a loudspeaker unit designed by utilizing the static electricity of the vibrating membrane. Background technique [0002] Nowadays, vision and hearing are the two most direct sensory responses for human beings. Therefore, scientists have been trying their best to develop various related systems that can reproduce vision and hearing for a long time. In recent years, with people's increasing requirements for sensory quality, and 3C products (Computer, Communication, Consumer Electronics) in pursuit of short, thin and light, a power-saving, light and thin, ergonomically designed speaker (Loudspeakers) , Whether it is paired with a large-sized planar speaker, or a headset as small as a walkman, or a stereo mobile phone, in the foreseeable future, there will be a lot of demand and application development for this technology. [0003] The driving methods of electro-aco...
