Abstract
The utility model relates to a loudspeaker diaphragm assembly with a saw-toothed voice coil, which comprises a voice coil and a dome diaphragm, wherein the coil of the voice coil is wound on a voice coil skeleton. The skeleton of the voice coil is circular-pipe-shaped. A turn of integrally-arranged saw-toothed sheets which are shrunk inwards for a certain angle is arranged at the top of the skeleton. The external surfaces of the integrally-arranged saw-toothed sheets are bonded together with the surface of the inner ring of the dome diaphragm. The loudspeaker diaphragm assembly has the characteristics that the diaphragm can be kept to vibrate integrally in operation, low-frequency distortion is reduced and a frequency range is widened; and moreover, the design of the saw-toothed voice coil skeleton properly increases the damping of the diaphragm, segmental vibration is suppressed, frequency bandwidth is widened, unevenness is reduced, distortion is reduced and medium-frequency and high-frequency sound quality is improved.
Description
Technical field
The utility model relates to a kind of sound film of loudspeaker group, particularly a kind of sound film of loudspeaker group of zigzag voice coil loudspeaker voice coil.
Background technology
In existing ball top vibrating membrane loudspeaker, plate diaphragm loud speaker, particularly tweeter, all be connected between voice coil loudspeaker voice coil and the vibrating diaphragm by binder, be that line connects between voice coil loudspeaker voice coil and the vibrating diaphragm, so the performance of binder directly affect the performance of loud speaker.Though present binder manufacturer has developed high frequency conductibility binder preferably, can not solve influence completely to tweeter.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of voice coil loudspeaker voice coil and vibrating diaphragm to adopt the sound film of loudspeaker group of the zigzag voice coil loudspeaker voice coil of plane connection structure.This structure has broken through tweeter and has been subjected to the restriction of vibrating diaphragm and abutting edge, has solved the influence of binder self performance to speaker performance, tonequality etc.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of sound film of loudspeaker group of zigzag voice coil loudspeaker voice coil, be included in the voice coil loudspeaker voice coil and the ball top shape vibrating diaphragm that are wound with coil on the speech coil framework, it is characterized in that: the skeleton of described voice coil loudspeaker voice coil is the pipe shape, several that are provided with at the skeleton top that a circle inwardly shrinks certain angle are made as the zigzag sheet of one, and several are made as the outer surface of zigzag sheet of one and the inner peripheral surface of described ball top vibrating diaphragm bonds together.
Characteristics of the present utility model are: speech coil framework is that face connects with being connected of vibrating diaphragm, improved the be connected area of speech coil framework greatly with vibrating diaphragm, make that the transition between speech coil framework and the vibrating diaphragm is slick and sly more, reduced of the influence of the performance of binder self to a great extent for speaker performance.Can keep vibrating diaphragm body vibration at work, reduce low-frequency distortion, the broadening frequency range.Simultaneously, the damping of vibrating diaphragm that this zigzag speech coil framework has designed suitable increase suppresses to cut apart vibration, expands frequency range, reduces unevenness, reduces distortion, has improved medium-high frequency tonequality.

Embodiment
As shown in Figure 1, 2, 3, a kind of sound film of loudspeaker group of zigzag voice coil loudspeaker voice coil, be included in the voice coil loudspeaker voice coil and the ball top shape vibrating diaphragm 1 that are wound with coil 2 on the speech coil framework, the skeleton of voice coil loudspeaker voice coil 2 is the pipe shape, several that are provided with at the skeleton top that a circle inwardly shrinks certain angle are made as the zigzag sheet 2-1 of one, and several are made as the outer surface of zigzag sheet 2-1 of one and the inner peripheral surface of described ball top vibrating diaphragm 1 bonds together.Its manufacture craft is as follows:
One, voice coil loudspeaker voice coil 1 manufacture craft flow process:
1, cuts, adopt automatic guillotine;
2, the machine that charges and attacks is automatically adopted in processing;
3, coil winding machine is adopted in coiling;
Two, vibrating diaphragm 2 manufacture craft flow processs:
1, hot-forming, hot pressing is cut edge simultaneously.
Three, voice coil loudspeaker voice coil 1 and vibrating diaphragm 2 group technology flow processs:
1, glue is played in vibrating diaphragm and voice coil loudspeaker voice coil abutting edge, adopts adhesive supplier;
2, voice coil loudspeaker voice coil and vibrating diaphragm are bonding, adopt localization tool.
Claims (1)
1. the sound film of loudspeaker group of a zigzag voice coil loudspeaker voice coil, be included in the voice coil loudspeaker voice coil (2) and the ball top shape vibrating diaphragm (1) that are wound with coil on the speech coil framework, it is characterized in that: the skeleton of described voice coil loudspeaker voice coil (2) is the pipe shape, several that are provided with at the skeleton top that a circle inwardly shrinks certain angle are made as the zigzag sheet (2-1) of one, and several are made as the outer surface of zigzag sheet (2-1) of one and the inner peripheral surface of described ball top vibrating diaphragm (1) bonds together.
