1. non-one-body molded because of hanging limit and plank, so still essential processing is bonding except that outward appearance is not beautiful on making, the also bad control of its quality has been because of having lacked the basin institute tool tapering that originally shakes, make flat when bonding the center difficulty align, so when bonding, must add strong fix in the middle of it.

2. made product is sticking mutually forming because of plank and outstanding limit, and useful life, the short generation slot that gets loose in the abutting edge easily under the vibration of experiencing all sorts of caused brokenly the noise that shakes as neighing to influence timbre matter, and severe patient even full wafer plank come off and do not survey use.

3. made in this way false loudspeaker, because of being that homophase is sticking forms for two kinds of soft or hard materials, make it no matter under low temperature, hot environment test, all can produce the aforementioned fault that gets loose, cause to produce and to change material at a certain specific environment and follow prescription with reply, make the product general context be subjected to great restriction, and on processing procedure, cause the virtual work waste of continuous test improvement.

Because of still having above-mentioned disappearance in view of commonly using false Loudspeaker diaphragm structure, this creator is devoted to research, through after the improvement experiment generation of the present utility model being arranged eventually in many ways.

Main purpose of the present utility model is providing a kind of false Loudspeaker diaphragm structural improvement, and its center counterweight can strike up partnership with vibrating diaphragm really, and long service life general environment scope is big, and the easily manufacturing of beauty treatment of one-body molded outward appearance.

Secondary objective of the present utility model in a kind of resulting structure that the center counterweight is held easily of design, correctly produces between contraposition and vibrating diaphragm when convenient its produced and well combines accurately.

For reaching above-mentioned purpose, the false Loudspeaker diaphragm structural improvement that the utility model is set, it mainly comprises: the direct one-body molded bigger surface layer body of an external diameter that is provided with on the median plate body, wherein the position, limit of this surface layer body directly circle be provided with the outstanding limit of disjunctor, when crossing the surface layer body moulding and outstanding limit is separated by leaves the gap and the hardness of this median plate body is strong; By this, make the specious unanimity of its vibrating diaphragm moulding, exempt from again to paste again between outstanding limit and median plate body and can reduce processing procedure and reduce cost, make anti-the shaking of the real finished product of the complete embedding of median plate body can not come off, can meet various test environment exoergic and effectively increase the service life.

Wherein, the soft rubber disk that this surface layer body is one of the forming, its periphery has the bonding antelabium of a circle, in connect the outstanding limit of semicircle of a circle evagination, and the disk of circle in being located at constitutes; This median plate body is that a concentric circle metal plate is embedded on the centre bit of surface layer body disk rear portion.

Wherein, this appropriate location, center, median plate body rear is provided with a little prominent platform, and its platform is provided with to be convenient to process holds the solid hole that connects.
