Problems solved by technology
However, the above-mentioned configuration needs to enhance the sound pressure output, so additional power components are required to cooperate with the drive. In this way, not only the device is bulky, but also uses more components, and the cost is also high
In addition, since the fixed structure 140 must fix the fixed electrode structures 110, 120 and the diaphragm 130, such an electroacoustic transducer structure cannot achieve flexible characteristics.

Embodiment Construction
[0056] The present invention proposes a loudspeaker structure with high reliability. The signal is input into the planar loudspeaker module at the same time, and the electret diaphragm with static electricity characteristics and the conductive electrode layer with water vapor blocking characteristics are used, and it is placed on a flat surface. The outer side of the speaker unit to improve the reliability of the planar speaker unit. In one embodiment, multiple sets of planar speaker units can be combined to achieve the effect of increasing the sound pressure output, thus avoiding the need to add a water vapor layer on the outer layer of the unit. The loudspeaker structure proposed by the present invention can further solve the problem that the structure and circuit of the planar loudspeaker are too complicated when the sound pressure power is increased.
[0057] In one embodiment, a protective layer with good water vapor barrier effect can be further added on the outside of t...

A reliable flat speaker unit and a speaker device with the same are provided herein. A conductive electrode of a vibrating membrane of the speaker unit is disposed on both utmost sides of the speaker unit to isolate the speaker unit from environmental moisture, which can significantly improve the reliance of the speaker device. A barrier layer can optionally be disposed on the external side of the conductive electrode to further isolating the speaker unit from moisture, which can improve the reliance and the lifetime of the speaker device. In an embodiment, at least a getter is disposed inside the flat speaker unit to absorb moisture therein. The speaker unit at least includes an electret vibrating membrane with a conductive electrode, a plurality of supporting members, and an electrode structure with a plurality of holes.
Description
technical field [0001] The present invention relates to a flat speaker, and in particular to a flat speaker with the property of blocking water vapor. 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 regeneration method of speakers, the main market is still dominated by dynamic speakers. 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 a...
