Self-adaption Q-value loudspeaker

Abstract

The invention provides a self-adaption Q-value loudspeaker comprising a support, an electromagnetic assembly, a voice coil, and a diaphragm. The electromagnetic assembly is supported by the support, and the voice coil is disposed on the magnetic gap of the electromagnetic assembly, and can vibrate freely. The outer periphery of the diaphragm is connected with the support by an edge, and the inner periphery is connected with the above mentioned voice coil. The edge is the pipeline edge, which is provided with a plurality of air exhaust holes. The self-adaption Q-value loudspeaker is advantageous in that the production technology is simple, and the cost is low; the problems of the conventional loudspeaker such as distortion and turbid unclear low frequency caused by the easy deformation of the edge in the large dynamic state can be solved; during the vibration of the diaphragm, the axial motion of the pipeline edge can be driven, and the edge can be compressed, and then the air quantity of the pipeline edge can be adjusted automatically, and the self-adaption change of the Q-value of the loudspeaker can be carried out, and therefore the transient response and the low frequency characteristic of the loudspeaker can be improved, and the high technical value and the high economic value can be provided.

[0002] The loudspeaker is an electro-acoustic transducer, which converts electrical energy into sound energy through physical effects. In recent years, with the development of stereo sound technology and people's pursuit of non-material life enjoyment, people's music appreciation ability has been continuously improved. The sound quality puts forward higher requirements. According to different physical effects, the most widely used electric speakers are the most widely used electric speakers. The cone speakers are the most widely used electric speakers at present. The speakers should have large power and large dynamic range. , small distortion, wider frequency response, and good transient response performance, but it is difficult for existing speakers to be perfect

[0003] The diaphragm is one of the most important parts of the speaker. The frequency response of the speaker is largely determined by the diaphragm. There is a ring around the diaphragm. The purpose of the ring is to connect the diaphragm to the frame. Axial positioning, so that the entire vibration system can freely move axially and prevent lateral vibration. The existing loudspeaker structure such as figure 1 and figure 2 As mentioned above, it is divided into an upper convex circular ring and a lower convex circular ring. The stiffness of the ring is one of the factors that determine the resonant frequency fo and the quality factor Q of the loudspeaker. The linearity of the amplitude of the vibration of the ring is also to a certain extent Affect the distortion of the speaker. Using the above two rings, when the speaker vibrates greatly, the compliance of the ring will become worse. With the increase of the vibration amplitude, the ring will no longer only move with the axial direction, but will be twisted. As a result, the distortion becomes larger, the transient response becomes worse, the low-frequency effect becomes ambiguous, the low-frequency is weak, and the effect is greatly reduced
