Plane loudspeaker unit and plane loudspeaker apparatus

Abstract

The invention discloses a plane loudspeaker unit and a plane loudspeaker apparatus. The plane loudspeaker unit comprises a first perforated electrode, a second perforated electrode and a diaphragm arranged between the electrodes and having an electret layer and an electrode layer, wherein air-gaps are formed between the first and second perforated electrodes and the diaphragm. In one embodiment, a plurality of supports are arranged between the first and second perforated electrodes and the diaphragm. In one embodiment, the plane loudspeaker apparatus comprises at least two stacked plane loudspeaker units. In one embodiment, both ends of a signal source are respectively connected with the first and second perforated electrodes. Or, in another embodiment, one end of signal source is electrically connected with the first and second perforated electrodes, and the other end of the signal source is electrically connected with the diaphragm, so that the diaphragm on the electret layer vibrates and generates sounds, thereby producing low THD effects.

Description

technical field [0001] The invention relates to a plane loudspeaker unit and a plane loudspeaker device. Background technique [0002] Nowadays, vision and hearing are the two most direct sensory responses for human beings. Therefore, scientists have been working hard to develop various regenerative visual and hearing related systems for a long time. At present, including the reproduction method of the speaker, the main market is still dominated by the dynamic speaker. However, with the increasing demand for sensory quality in recent years, and the 3C products (Computer, Communication, Consumer Electronics) in pursuit of short, light and thin, a speaker that is power-saving, light and thin, and can be designed according to ergonomic requirements, no matter Whether it is matched 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 technolo...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a flat speaker unit and a flat speaker device, which solves the problem that the flat speaker and the driving circuit are too complicated when the sound pressure power is increased in the prior art, and improves product diversification.
