Simultaneously, the leads are shaped into arc structures, the leads and the vibrating film are arranged in the separated mode, and the leads are suspended above the vibrating film without dispensing fixation of the vibrating film, therefore, the leads can acquire a certain vibration allowance, and the problem of uneven weight of the vibrating film caused by the leads can be avoided.
Description
Technical field
The present invention relates to the dynamic-circular electroacoustic device art, refer in particular to a kind of simple in structure, stable and reliable for performance and do not have a sound membrane structure and preparation method thereof of the dynamic-circular electroacoustic device of lead-in wire broken string phenomenon.
Background technology
Shown in Fig. 1 a and Fig. 1 b, the sound membrane structure system of existing dynamic-circular electroacoustic device include copper band support 10 ', vibrating diaphragm 20 ' and voice coil loudspeaker voice coil 30 ', vibrating diaphragm 20 ' outer ring edge be engaged in this copper band support 10 ' on, voice coil loudspeaker voice coil 30 ' apical margin be engaged in vibrating diaphragm 20 ' the bottom surface.The manufacture method of the dynamic-circular electroacoustic device sound membrane structure that this kind is existing is: at first need with glue spots vibrating diaphragm 20 ' on, then with tool with vibrating diaphragm 20 ' with voice coil loudspeaker voice coil 30 ' combine, then at vibrating diaphragm 20 ' edge point fixed point glue, with voice coil loudspeaker voice coil 30 ' lead-in wire be fixed on vibrating diaphragm 20 ' end, glue then goes between, with voice coil loudspeaker voice coil 30 ' lead-in wire be fixed on from terminal to the voice coil loudspeaker voice coil 30 that is fixed on vibrating diaphragm 20 ' end ' lead-in wire vibrating diaphragm 20 ' on, wiring board welding with copper band support 10 ' outer then will go between.
Though the sound membrane structure of aforementioned dynamic-circular electroacoustic device can realize its basic function of being talked about, reality use and production process in find still to have many deficiencies, existing with its shortcoming conclusion following points:
1), long easy broken string goes between, since traditional copper band support 10 ' for to make by copper conductive material, its integral body all has electric conductivity, therefore can not be directly copper band support 10 ' on produce the pad structure of mutual not conducting, be not easy to directly copper band support 10 ' on connect voice coil loudspeaker voice coil 30 ' two lead-in wires 31 ', and need to prolong lead-in wire 31 ' with the circuit board in the pedestal outside on pad 40 ' be electrically connected, therefore need to prolong lead-in wire 31 ' length to vibrating diaphragm, because lead-in wire will connect together with the wiring board outside the support, and voice coil leads is very thin usually, therefore causes the voice coil leads broken string easily.
2), some lead-in wire glue will increase the thickness of vibrating diaphragm 20 ' part position, causes vibrating diaphragm 20 ' weight inhomogeneous, like this, cause vibrating diaphragm 20 ' imbalance, can influence the tonequality of product, and the homogeneity of product of making is not good enough.
3), the manufacture craft more complicated because some lead-in wire glue can only manual operations, so poor reliability.
Summary of the invention
Main purpose of the present invention provides sound membrane structure of a kind of dynamic-circular electroacoustic device and preparation method thereof, and it is simple in structure, stable and reliable for performance and do not have a problem of lead-in wire broken string.
For achieving the above object, the present invention adopts following technical scheme:
A kind of sound membrane structure of dynamic-circular electroacoustic device, include outer coil support, vibrating diaphragm and voice coil loudspeaker voice coil, the middle part of being somebody's turn to do outer coil support has a containing hole that runs through up and down, this vibrating diaphragm and voice coil loudspeaker voice coil are arranged in this containing hole, and the outer ring edge of vibrating diaphragm is engaged on this outer coil support, and the apical margin of voice coil loudspeaker voice coil is engaged in the bottom surface of vibrating diaphragm, and this outer coil support is made for the material that pad can be set, outer coil support is provided with the pad that at least two separate types insulated from each other distribute, and the tail end of the lead-in wire of voice coil loudspeaker voice coil is electrically connected with this pad respectively.
As a kind of preferred version, described two lead-in wires have the arcuate structure of typing, make separate type setting between lead-in wire and the vibrating diaphragm.
As a kind of preferred version, described outer coil support is copper-clad plate or soft board.
As a kind of preferred version, the shape of described voice coil loudspeaker voice coil is same or similar with the shape of the containing hole of outer coil support.
As a kind of preferred version, described voice coil loudspeaker voice coil is runway shape, and the containing hole of corresponding outer coil support is runway shape or rectangle.
As a kind of preferred version, described voice coil loudspeaker voice coil is rounded, the rounded or rectangle of containing hole of corresponding outer coil support.
As a kind of preferred version, described voice coil loudspeaker voice coil ovalize, the containing hole ovalize or the square of corresponding outer coil support.
As a kind of preferred version, described voice coil loudspeaker voice coil is square, and the containing hole of corresponding outer coil support is square.
A kind of manufacture method of sound membrane structure of described dynamic-circular electroacoustic device comprises the steps:
Steps A, voice coil loudspeaker voice coil and the outer coil support that has a pad are fixed on the tool;
Step B, the lead-in wire of voice coil loudspeaker voice coil and pad on the outer coil support are welded;
