Abstract

The present invention provides a loudspeaker diaphragm and a loudspeaker. The loudspeaker diaphragm comprises a diaphragm body, the diaphragm body is a rectangular basin-like structure, the basin-likestructure comprises a rectangular bottom surface, an annular side wall and extruded outwards rectangular edge which are connected in order from inside to outside, the four corners of the rectangularbottom surface and the rectangular edge are circular beads, the annular side wall is constructed to a three-dimensional array structure formed by a plurality of irregular surface bodies, and the adjacent irregular surface bodies are mutually connected through the edges of the irregular surface bodies. The rectangular basin-like structure of the diaphragm and the triangular three-dimensional arraystructure can improve the rigidity modulus, can reinforce robustness and can improve the conversion of the acoustic energy; paper pulp is employed as raw materials and carbon fiber and wool are addedto enhance the service life and self-damping of the diaphragm while reducing the diaphragm quality; and moreover, the loudspeaker diaphragm and the loudspeaker are not prone to generation of segmentation vibration and focusing so as to reduce harmonic distortion and phase distortion.

Description

technical field [0001] The invention relates to the technical field of electric loudspeakers, in particular to a loudspeaker diaphragm and a loudspeaker equipped with the loudspeaker diaphragm. Background technique [0002] The loudspeaker is used to convert electrical energy into sound energy, and usually includes a basin-shaped shell, a vibration system and a magnetic circuit system housed in an inner cavity surrounded by the shell, and the vibration system includes a diaphragm and a voice coil connected together. Among them, the loudspeaker diaphragm is the main part of the loudspeaker. The loudspeaker (especially the mid-woofer) converts the electromagnetic force through the voice coil in the center of the diaphragm to the diaphragm closely connected with it to form a mechanical force and produce sound to complete the electric-force-acoustic conversion. In the process of electric-force-acoustic conversion, the diaphragm is the middle mechanical part and the most importa...
