Outer pad, interior fixed part is equipped with several interior pads being electrically connected with lead, and passes through shape between interior fixed part and outer fixing portion
Change portion be connected, due to the deformations can with vibrational system move up and down, the both ends of lead with vibrational system above and below
Movement effectively eliminates lead and improves loudspeaker to the involve power of vibrational system so as to avoid the generation of polarization situation
Whole acoustical behavior.
The Voice coil assemblies 2 of loudspeaker are set the first voice coil 21 interconnected and by the technical solution of the utility model
Two voice coils 22, by the voltage difference of detection the first voice coil 21 and 22 junction of the second voice coil, to calculate and constantly correct voice coil group
The shock position of part 2, to enhance the stability of the vibration of vibrating diaphragm 1, moreover, introducing centring disk 8 to flexibly support entire vibration system
System, 8 outside of centring disk is electrically connected with shell 3, inside is electrically connected with each lead of Voice coil assemblies 2 for this, and can be with vibration system
System movement avoids Voice coil assemblies 2 from polarization situation occur to effectively eliminate lead to the involve power of vibrational system, it follows that this
The technical solution of utility model can effectively improve the whole acoustical behavior of loudspeaker.
Further, the lower end surface of Voice coil assemblies 2 or lower end side are connect with the interior fixed part of centring disk 8.It can manage
Solution, so set, while centring disk 8 eliminates lead involve power, moreover it is possible to play the role of supporting Voice coil assemblies 2, effectively mention
The convenience and reliability that high Voice coil assemblies 2 are installed.
Further, first enters line 212 and the first outlet 213 is connected to the first noumenon 211 deviates from the second ontology 221 one
Side, second enters line 222 and the second outlet 223 is connected to the side that the second ontology 221 deviates from the first noumenon 211.It is appreciated that such as
This setting, reduces the inlet-outlet line of lead, the interference to connecting between the first noumenon 211 and the second ontology 221 as far as possible.It needs to illustrate
, in other embodiments, at least one of first lead 211 and the second lead 221 are from the first noumenon 211 and the second ontology
221 opposed facing sides are drawn, and the design is without being limited thereto.
Further, it is set on interior fixed part there are four interior pad, outer fixing portion is equipped with to be corresponded with four interior pads
Four outer pads of electrical connection, first enters line 212, the first outlet 213, second enters line 222 and the second outlet 223 respectively with four
A interior pad electrical connection.It is appreciated that pad in one is respectively set in corresponding each lead, be conducive to avoid occurring between each lead
The case where crossfire, an and outer pad is arranged in corresponding each interior pad, advantageously ensure that centring disk 8 is electrically connected with shell 3 can
By property.Specifically, centring disk 8 is multilayered structure, is embedded with conductive copper foil layer, which shows at each interior pad 821
Outside being exposed to, mutually to be welded with corresponding lead.It should be noted that the design is without being limited thereto, it is interior solid in other embodiments
Determine to set in portion there are two interior pad, first enters line 212, the first outlet 213, second enters in line 222 and the second outlet 223 two-by-two
It is electrically connected with pad 821 in one.
Referring to figure 5 and figure 6, in the present embodiment, centring disk 8 includes the first centring disk 81 and the second centring disk 82,
First centring disk 81 and the second centring disk 82 are connected on two short sides of Voice coil assemblies 2.It is appreciated that by centering branch
Piece 8 is set as two, advantageously reduces the consumptive material of centring disk 8, then reduces the integral material cost of loudspeaker.Certainly, Yu Qi
In his embodiment, the first centring disk 81 and the second centring disk 82 are connected in two long sides of Voice coil assemblies 2.It should say
Bright, the design is without being limited thereto, and the first centring disk 81 and the second centring disk 82 are connected to the two of Voice coil assemblies 2 and grow
Bian Shang.
It is easily understood that Voice coil assemblies 2 enter line and outlet in design, the same side positioned at voice coil will lead to voice coil
The screen resilience being subject to is inconsistent, so that two sides amplitude is different, so that product is generated polarization, influences the acoustical behavior of loudspeaker, because
This, in the present embodiment, referring to Figure 2 to Figure 4, the first noumenon 211 and the second ontology 221 tool there are four corner, first enter line 212,
First outlet 213, second enter line 222 and the second outlet 223 and draw respectively from four corner locations.It is appreciated that so setting
It sets, so that polarization power caused by the lead of 2 all directions of Voice coil assemblies is cancelled out each other, reach product vibrational system in the horizontal direction
On active balance, effectively improve the whole acoustical behavior of loudspeaker.It should be noted that first enters line 212 (second enters line
222) and the first outlet 213 (the second outlet 223) is not limited to draw from two adjacent corners or two opposite corners, only
The polarization power for wanting it that the two can be made respectively to generate is cancelled out each other.Specifically, the first noumenon 211 has first be oppositely arranged
Long side 211a and the second long side 211b, first enters line 212 connects with the first long side 211a, the first outlet 213 and the second long side
