Abstract

The invention discloses diaphragm and relates to the technical field of an electroacoustic product. The diaphragm comprises a macromolecular material layer and a silicone rubber layer. A surface processing layer is combined between the macromolecular material layer and the silicone rubber layer. According to the diaphragm, a preparation method thereof and a loudspeaker comprising the diaphragm provided by the invention, the problem that in the prior art, a diaphragm structure is instable is solved. According to the diaphragm provided by the invention, a diaphragm body and a diaphragm middle part are combined firmly, the structure stability of the diaphragm in vibration is improved, and the yield of the product is improved. The invention also discloses the preparation method for the diaphragm and the loudspeaker comprising the diaphragm.

Description

technical field [0001] The invention relates to the field of electroacoustics. More specifically, it relates to a diaphragm with good structural stability, its manufacturing method and a loudspeaker including the diaphragm. Background technique [0002] Acoustic devices such as speakers, as a device that can convert electrical energy into sound energy, have been widely used in mobile terminals such as computers and mobile phones. And with the continuous development of electronic technology and information industry and the continuous improvement of market demand, people's requirements for the performance of loudspeakers are also getting higher and higher. Diaphragm is one of the important parts of loudspeaker to realize electro-acoustic energy conversion. Its performance directly affects the sound reproduction effect of loudspeaker. Therefore, the research on the improvement of the structure and performance of diaphragm has also received more attention. [0003] In the exis...
