Full-frequency-band and ultrahigh frequency loudspeaker vibration diaphragm

The invention relates to the technical field of the loudspeaker vibration diaphragms, especially a full-frequency-band and ultrahigh frequency loudspeaker vibration diaphragm. The full-frequency-bandand ultrahigh frequency loudspeaker vibration diaphragm comprises a vibration plate body, a vibration plate edge, and a voice coil; the voice coil is located at the bottom of the vibration plate body,and a dustproof cap with a clasp is covered on the voice coil; the vibration plate edge is located at an upper part of the vibration plate body and cooperated with the vibration plate body; and a bevel is arranged at a combination part of an inner edge of the vibration plate edge and the vibration plate body. Through the full-frequency-band and ultrahigh frequency loudspeaker vibration diaphragmdisclosed by the invention, the bevel is added at the combination part of the inner edge of the vibration plate edge and the vibration plate body to greatly enhance the strength of a cone by utilizingthe reflection principle of
