Substrate 23 be evenly dividing as three regions, three groups of printed coils 24 are separately positioned in three regions of substrate 23.This is multi-thread
The coil group 2 of the coil structures three irregular vibrating diaphragms that can both arrange in pairs or groups use, and the normal vibrating diaphragm that can also arrange in pairs or groups uses；Such as Figure 10 institute
Show, when three irregular magnetic diaphragms of arranging in pairs or groups are in use, three magnetic diaphragms can issue different sound, so that one
A loadspeaker structure can issue alternative sounds, increase the use diversity of loadspeaker structure.When the normal magnetic vibration of collocation
Film 3 is in use, can increase the power of loadspeaker structure.
Above-mentioned magnetic diaphragm 3 is arbitrary structures, such as laminated structure, chondritic, pyramidal structure, disk construction, ball
Push up shape structure, horn type etc..As shown in figure 11, when magnetic diaphragm 3 is chondritic, the sound broadcasting of loudspeaker is that have face
To, when magnetic diaphragm is spherical, the covering scope that sound plays just will increase several times to tens times, stereosonic effect
Fruit also can be more obvious, thus optimizes the three-dimensional sound of loadspeaker structure.As shown in figure 12, when magnetic diaphragm 3 is laminated structure,
In order to optimize the stereo sound effect fruit of loadspeaker structure, the quantity of magnetic diaphragm 3 can be arranged it is more than two, while by two with
On magnetic diaphragm 3 connection form the periphery that coil group 2 is arranged in cyclic structure.
The utility model it is critical that the vibrating diaphragm of the utility model have magnetism, formed magnetic diaphragm 3, such loudspeaking
Device structure only needs shell 1, coil group 2 and magnetic diaphragm 3 to can be carried out sounding, realizes the conversion of electric signal to acoustical signal.This
The loadspeaker structure of utility model is by setting magnetic diaphragm 3 for vibrating diaphragm, to remove heavy magnet in loadspeaker structure
In use, reduce the volume of loadspeaker structure, realize the miniaturization of loadspeaker structure, make loadspeaker structure application more
Flexibly.Meanwhile because the magnetic field of magnetic diaphragm 3 and the magnetic field of coil group 2 are closer using magnetic diaphragm 3, loudspeaker knot is improved
The audio of structure；And use magnetic diaphragm 3 that magnetic field is made directly to manipulate vibrating diaphragm and determine audio, also further improve loudspeaker
