Problems solved by technology

However, the sound cone of the V-shaped groove structure will cause the problem of easy deformation between the side plates of the sound cone in the circumferential direction ( figure 1 As shown by the arrow in ) and the connection problem between this complex V-groove end structure and other parts of the horn (the joint is long and irregular in shape), it will face potential split vibration and sound distortion, which needs to be solved in the future. make further improvement

Abstract

The invention provides a loudspeaker and a cone thereof. The cone comprises a first diaphragm and a first annular reinforcing rib which are basically horn-shaped, the first diaphragm comprises a plurality of V-shaped grooves with openings gradually increasing, and the upper edges of the adjacent V-shaped grooves are connected to form the first diaphragm. An inner ring of a first annular reinforcing rib is connected to a horn-shaped opening end of a first vibrating diaphragm; The end portions of the V-shaped grooves cannot be bent and deformed along the folding lines after being stressed in thecircumferential direction, the structural strength and rigidity of the V-shaped grooves in the circumferential direction are enhanced, and therefore the V-shaped grooves can bear long-time high-frequency vibration without deformation, the distortion degree is low, and the tone quality effect is good.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker and a sound cone thereof. Background technique [0002] The sound cone is one of the important parts applied to the loudspeaker, which mainly plays the role of sound radiation. The sound of various frequencies is generated by its vibration. Due to the large frequency range of the sound, the vibration frequency of the sound cone ranges from low frequency to high frequency. The higher the frequency, the greater the requirement for the structural strength of the sound cone. In the case of insufficient strength, long-term use is prone to deformation, resulting in poor sound effects. [0003] The shape of the existing sound cone is generally conical, and its conical surface is a smooth curved surface with low strength and high brittleness. It is prone to deformation during long-term use, and the vibration of the sound division is relatively large, which may easily ...
