Definitions

  • the invention relates to a loudspeaker diaphragm.
  • the existing speaker requires the speaker to vibrate and vocalize, and puts higher requirements on various components of the speaker.
  • Conventional speakers use concave cone diaphragms made of paper or other thin materials. Generally, the diaphragm is required to have light and good stiffness in frequency response. Due to the limitation of materials, the rigidity will increase the weight and reduce the weight. It is bound to affect the rigidity of the diaphragm and increase the generation of the split vibration.
  • a flat-faced thin plate is generally used as the diaphragm. The diaphragm of this structure is more likely to generate harmful split vibration, and the sound quality becomes worse.
  • An object of the present invention is to provide a speaker diaphragm having a desired rigidity and at the same time having a lighter weight and having a flat front surface protruding from the above-mentioned problems.
  • the diaphragm of the present invention has a solid body structure in which the front surface is flattened on the back surface, and a voice coil connecting hole is provided on the back surface.
  • the invention can be made of polyethylene foamed plastic which is light and hard to minimize the weight of the diaphragm.
  • the technical effect of the present invention is that the back surface of the diaphragm of the present invention is protruded, and the overall rigidity of the diaphragm is enhanced by a structure similar to triangulation, which effectively reduces the generation of the split vibration and improves the sound quality of the speaker.
  • FIG. 1 is a schematic structural view of a speaker to which a diaphragm of the present invention is applied. detailed description
  • the diaphragm of the present embodiment is a solid body made of polyethylene foamed plastic, the front surface 2 of which is flat, the back surface 1 of which protrudes rearwardly in the shape of a cone, and the voice coil connection hole 3 is provided in the center of the back surface 1. .
  • the diaphragm of the present embodiment is bonded to the folding ring 5 at the periphery 4, and the voice coil connecting hole 3 is bonded to the driving voice coil 6, thereby replacing the existing concave pyramid diaphragm with other components of the speaker and assembling into a flat plate shape. speaker.
  • the diaphragm of the present invention may have a shape such as a paraboloid or a trapezoidal shape.

Abstract

L'invention porte sur une membrane de haut-parleur formant une structure rigide présentant une surface frontale plate (2), et une surface dorsale saillante (1) munie d'une ouverture logeant une bobine vocale (3). Compte tenu de la rigidité, le poids peut être réduit, ainsi que la qualité du son du fait de la division des vibrations.
