Problems solved by technology
However, when the diaphragm is used in water, because the resistance of water is much greater than that of air, the impact force is also stronger. The traditional diaphragm is prone to abnormal noise when it is impacted underwater. In addition, the working principle of the flat earphone itself limits the deformation of the diaphragm. range, so traditional flat-panel headphones cannot really be used underwater even if they overcome the waterproof performance

Abstract
The invention provides an underwater available panel earphone with an adjustable double-loop diaphragm tensioning mechanism. The underwater available panel earphone comprises a waterproof electromagnetic transducer unit, the electromagnetic transducer comprises an outer shell, a permanent magnet plate, a vibrating diaphragm arranged opposite to the permanent magnet plate, an elastic layer arranged between the vibrating diaphragm and the permanent magnet plate, and a fixing component used for fixing the vibrating diaphragm. the periphery of the vibrating diaphragm is fixed by the adjustable tensioning hoop, so that the vibrating diaphragm can respectively adapt to different vibration amplitude requirements in air and water, and the use requirements in different use scenes can be obtained; an elastic layer is adhered to the outer surface of the vibrating diaphragm and is arranged between the vibrating diaphragm and the permanent magnet plate, so that the toughness of the vibrating diaphragm can be improved, the vibration of the vibrating diaphragm can be more uniform, the vibrating diaphragm is prevented from being in contact with the permanent magnet plate due to water flow impact, and unnecessary noise or abnormal sound can be prevented from being generated.
Description
Technical field [0001] The present invention relates to the field of audio output devices and more particularly relates to an underwater earphone plates available, particularly its diaphragm tensioning mechanism. Background technique [0002] Planar electromagnetic transducer is a flat plate in the prior art headset. This type of electromagnetic transducer assemblies typically comprises a permanent magnet, with the diaphragm disposed opposite the permanent magnet assembly, and fixing means for fixing the diaphragm member. [0003] Conventional electromagnetic transducer permanent magnet assembly used with a plurality of elongated permanent magnets, each permanent magnet having two opposite poles, the permanent magnets are arranged in parallel relation on a surface of both sides thereof, such that N poles and S alternately the non-magnetic pole member and securely joined together by. Resin diaphragm is a thin film formed by the "S" shape or the "back" of the coil-shaped pattern on...
