Description
【Technical field】
The present invention relates to the technical field of loudspeaker, more particularly to a kind of multifunction speaker.
【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.
Find in use, the performance of loudspeaker can not be lifted very well as permanent magnet using ferrite magnetic steel, still
It is all too high using Nd-Fe-B magnet steel as permanent magnet cost, and voice coil loudspeaker voice coil can cause magnetic to return in high temperature and upper and lower high-speed cruising
The chaotic touching T iron axial wall in road, damages voice coil loudspeaker voice coil, the service life of voice coil loudspeaker voice coil is shorter；For mega bass loudspeaker, in mega bass work
Make under state, cause air compression to have little time to exclude from beneath because high intensity moves up and down, directly impact dust cover, make
Into there is the prominent noise of thumping, can also cause dust cover to damage, and because the vibrations of sound basin high intensity cause confusion and collision formed it is miscellaneous
Sound or damage, influence loudspeaker quality and life-span；In addition, existing subwoofer can only come out full range music, do not have
The regulatory function of supper bass intensity, high-frequency signal is easily caused to damage subwoofer.In order to solve problem above, it is necessary to
It is proposed a kind of multifunction speaker.
