【Technical field】
The present invention relates to the technical field of loudspeaker, the diaphragm of loudspeaker system of more particularly to a kind of anticreep even.
【Background technology】
Loudspeaker is also known as " loudspeaker ", is a kind of very conventional electro-acoustic transducer device, in the electronic electric equipment of sounding
It can be seen.Loudspeaker has numerous species, but its basic operation principle is similar, is that one kind converts electrical signals to
The element that voice signal is reset.At present, the most widely used is dynamic speaker, and it is by vibrating membrane, voice coil loudspeaker voice coil, permanent
Magnet, support etc. form.After the voice coil loudspeaker voice coil of loudspeaker is passed through tone currents, voice coil loudspeaker voice coil just produces the magnetic of alternation in the presence of electric current
, permanent magnet also produces the constant constant magnetic field of a size and Orientation simultaneously.It is big due to magnetic field caused by voice coil loudspeaker voice coil
Small and direction is constantly changing with the change of tone currents, and the interaction in two such magnetic field makes voice coil loudspeaker voice coil make perpendicular to voice coil loudspeaker voice coil
The motion of the middle sense of current, because voice coil loudspeaker voice coil is connected with vibrating membrane, so as to drive vibrating membrane to produce vibration, caused by vibrating membrane vibration
The vibration of air and send sound.When the electric current of input voice coil loudspeaker voice coil is bigger, the active force in its magnetic field is bigger, the width of vibrating membrane vibration
Degree is also bigger, and sound is then louder.
Loudspeaker is mainly made up of magnetic circuit system and vibrating diaphragm system, and the quality of vibrating diaphragm system directly determines the matter of loudspeaker
Amount.For subwoofer, the Oscillation Amplitude of vibrating diaphragm is larger, can cause to determine the bonding strength between core branch piece, voice coil loudspeaker voice coil, sound basin
Reduce, stability reduces, and causes both poor sound quality.In order to solve this problem, it is necessary to propose that a kind of loudspeaker of anticreep even shakes
Membranous system.
【The content of the invention】
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of diaphragm of loudspeaker system of anticreep even
