The electric connection mode of six voice coil units will be done exemplary introduction below.
Fig. 4-1 is six voice coil loudspeaker voice coil connection diagrams according to the embodiment of the present invention.As shown in Fig. 4-1, respectively
Three the voice coil unit series connection that will be located on same straight line are two branch roads, then by two branch circuit parallel connections.
Fig. 4-2 is six voice coil loudspeaker voice coil connection diagrams according to another embodiment of the present invention.As shown in the Fig. 4-2,
It is two branch roads that the voice coil loudspeaker voice coil of two voice coil loudspeaker voice coils and opposite side centre that will be located in same straight line corner respectively is connected, so
After by two branch circuit parallel connections.
The most also can there be the flat woofer of four voice coil units, four sounds
The mode of the electrical connection of coil unit the most also has two kinds, as shown in Fig. 5-1 and Fig. 5-2.
Fig. 5-1 is four voice coil loudspeaker voice coil connection diagrams according to the embodiment of the present invention.As shown in fig. 5-1, respectively
Two the voice coil unit series connection that will be located on same straight line are two branch roads, then by two branch circuit parallel connections.
Fig. 5-2 is four voice coil loudspeaker voice coil connection diagrams according to another embodiment of the present invention.As shown in Fig. 5-2,
The two voice coil loudspeaker voice coil series connection that will be located in same diagonal corner respectively are two branch roads, then by two branch roads.
According to the voice coil unit connected mode shown in Fig. 4-2 and Fig. 5-2, if on a branch road one or
Multiple driver elements go wrong, and flat woofer also is able to normally work, because also having additionally
Article one, branch road is being uniformly distributed around vibrating diaphragm, makes vibrating diaphragm uniform force.Simultaneously as the two of FPCB
Hold thinner, and have the bending of certain radian, therefore resistance to vibrating diaphragm during diaphragm oscillations can be dropped to
Minimum, and enable vibrating diaphragm uniform force.
The driver element used due to the present invention is more, therefore, in inventive embodiment, uses FPCB
It is electrically connected driver element and external circuit, is compared to common conductor connections, use FPCB
Simplified manufacturing process can be made, save the inner space of speaker, and stablizing of speaker can be improved
Property.
By above-mentioned embodiment it can be seen that the flat woofer of present invention offer, use extremely
Few four driver elements are arranged on four corners in the top dome portion of vibrating diaphragm, additionally can also arrange on major axis
Two even more than driver element, it is big that this structure uses undersized voice coil unit and magnetic circuit unit to drive
The vibrating diaphragm of the woofer of size, it is possible to reduce the thickness of woofer, additionally it is possible to save Magnet
Size reduction cost, improves the sensitivity of woofer.It addition, the driver element of homonymy on major axis limit
The most on the same line and gap ratio is not the arrangement of ratio of integers, and on opposite side centrally located two
The spacing being smaller than between the driver element of corner two between driver element, this arrangement acts on
Vibrating diaphragm, can avoid the defect caused due to the resonance of vibrating diaphragm；Simultaneously drive power uniform, can balance
Drive vibrating diaphragm, more powerful electronic installation can be acted on, and flat woofer structure is lighter
Thinner；Shell uses aluminum alloy materials, and aluminum alloy materials strength ratio is relatively big, and stability is high；Use FPCB
Connect voice coil loudspeaker voice coil and external circuit, it is possible to save space, and the lead-in wire of the voice coil loudspeaker voice coil being combined with vibrating diaphragm directly with
The pad solder of FPCB, can avoid the broken string of the voice coil leads caused due to vibration of membrane of shaking.
The flat bass loudspeaker proposed according to the present invention is described in an illustrative manner above with reference to accompanying drawing
Device.It will be understood by those skilled in the art, however, that the flat bass that the invention described above is proposed
Speaker, it is also possible to make various improvement on the basis of without departing from present invention.Therefore, the present invention
Protection domain should be determined by the content of appending claims.
