Loudspeaker and its terminal assemblies
Technical field
The application is the terminal that is connected more particularly, to the voice coil leads of loudspeaker about loudspeaker and its terminal assemblies
Component.
Background technique
The basic principle of sound of loudspeaker be signal is input to voice coil (voice coil) generate magnetic field, by with fixation
Mutual suction reprimand effect between magnetic pole, piston motion before and after being generated in magnetic gap, so that vibrating diaphragm is also with piston before and after voice coil
Movement generates vibration, and then pushes air resonance, throughout auditory nerve on human ear ear-drum, therefore can receive this vibration and hear sound
Sound.Therefore the electric connection of voice coil is very crucial.
Traditionally, voice coil is to be welded to terminal plate by lead-out wire, reaches electric connection.Terminal plate is to be riveted on support chip
On.Therefore, the length of support chip has to be larger than the outer diameter of magnet, be just avoided that terminal plate be riveted on support chip after and magnet
Between interference.Support chip is bigger, then the outer diameter of panel is also bigger, in this way, be easy for influencing speaker overall dimensions
The design of selection and structure.
Furthermore support chip is usually plastic material, if because its insulator and easy molding.And the support chip of high pitch is past
Toward too thick, even more Bao Yuehao is not intended to, voice coil overall height can be allowed to reduce.Therefore support chip general thickness is 1.6mm.However
When voice coil lead-out wire is welded on terminal plate, the temperature (430 DEG C) of solder head be easy to cause support chip to deform, and leaves hidden danger.
In addition to this, there are two types of methods when connecing input signal cable for terminal plate:(1) directly signal wire is welded on scolding tin
On terminal plate;The disadvantage is that being inconvenient to dismantle and replacement high pitch.Same scolding tin operation is possible to plastic support to scald to deform to cause
Voice coil lead-out wire is torn.(2) plug-in unit is attached using terminal plate;Disadvantage is also to be inconvenient to assemble and replace high pitch,
Pluggable terminals piece to plug-in unit needs that plastic support is easy to fracture using biggish strength.

Specific embodiment
It reads herein for convenience, therefore "upper", "lower", "left", "right" is pointed out according to schema, the purpose is to point out each member
Reference relative position between part, rather than to limit the application.
The stereoscopic schematic diagram of loudspeaker 1 is shown in Fig. 1.It please also refer to Fig. 2 and Fig. 3.The loudspeaker 1 of the application wraps
It includes:Voice coil 25, support chip 22, gasket 21, two electric wires 12 and terminal assemblies 11.Two electric wires 12 be actually two side by side
Electric wire.Voice coil 25 includes two leads 251.Support chip 22 surrounds voice coil 25.Two leads 251 are located at the upper table of support chip 22
Face.Preferably, the upper surface of support chip 22 includes two lead guide grooves 221, for putting two leads 251 respectively.21, gasket
Under support chip 22.Preferably, the lower surface of support chip 22 includes one first wire guide channels 222, and the upper table of gasket 21
Face includes one second wire guide channels 211, which corresponds to each other with second wire guide channels 211, so that two
Electric wire 12 is between the first wire guide channels 222 and second wire guide channels 211.Two electric wires 12 are connected with two leads 251 respectively
It connects, such as is welded directly together.The edge of support chip 22 be equipped with a connecting hole 223, with benefit welding after two electric wires 12 to
Under extend to terminal assemblies 11.
Since lead 251 is welded on electric wire 12, can avoid scorching support chip 22.In addition, can also be saved using electric wire 12
Terminal chip architecture is gone, therefore, the outer diameter of support chip 22 is smaller than the outer diameter of magnet 27, and the overall dimensions of loudspeaker 1 can more contract
It is small.
In one embodiment, loudspeaker 1 also includes a T-type iron 23.T-type iron 23 includes a hole 231, and the gasket 21 wraps
Include a through hole 212.Two electric wires 12 pass through the through hole 212 and the hole 231.Preferably, loudspeaker 1 further includes an aluminum pipe

In hole 231.Aluminum pipe 13 has the function of guiding simultaneously, and two electric wires 12 of guiding smoothly reach at terminal assemblies 11, and avoid with
Other elements (such as T-type iron or magnet) interfere with each other.
In one embodiment, loudspeaker 1 further includes a heat-dissipating cavity 10, terminal assemblies 11 be located at the heat-dissipating cavity 10 it
It is interior, and the outer surface of the heat-dissipating cavity 10 is multiple radiating fins.Preferably, loudspeaker 1 further includes an acoustical cotton 26, the suction
Sound cotton 26 also in the heat-dissipating cavity 10 within, and the acoustical cotton 26 is located on terminal assemblies 11.Heat-dissipating cavity 10 is not only
Inner space accommodating terminal component 13 is provided, inner space can also reduce the resonance frequency of high pitch simultaneously.Heat-dissipating cavity 10
The fin structure of outer surface can also accelerate to radiate.
Fig. 4 A and Fig. 4 B are please referred to, the terminal assemblies 11 of the application include:Two-terminal, a block set 112 and two fixing heads
114.Each terminal includes a terminal head 1111 and a terminal body 111.Block set 112 includes two-terminal seat 1120.Two-terminal seat
1120 accommodate two-terminal ontology 111 respectively, and two-terminal head 1111 exposes to except block set 112.Two fixing heads 114 are respectively with two
Terminal head 1111 combines, and two electric wires 12 are separately fixed at two-terminal.For example, fixing head 114 can be nut, terminal head 1111
For stud type, fixation is screwed togather each other.Two electric wires 12 can be centered around terminal head 1111, and reinforce fixing using clout body 113.It is excellent
Choosing, each terminal head 111 include one perforation 110, can supply lines 12 pass through.
Heat-dissipating cavity (for example, back cavity of high pitch loudspeaker) inside is ensconced in the terminal assemblies of the application, is not take up any
External size, that is, interface position is hidden in the bottom of loudspeaker.When connecing input signal cable, only need to use the plug of standard as
Binding post, the mode of connection of similar speaker facilitate plug and replacement loudspeaker.It thus also can avoid the various of scolding tin wiring
Drawback improves pinch effect, improves structural compactness and stability, and eliminating phase interference simultaneously, obtains good linear anti-
It answers.
Although the application is disclosed as above with embodiment, so it is not limited to this case, any skilled person,
It does not depart from spirit and scope, when can make some changes and embellishment, therefore the protection scope of the application is attached after view
The range that is defined of claims subject to.
