Multiple snak links are equipped with, the loudspeaking component is engaged by snak link with the occlusal crib of magnet.
It is not single one wherein it should be noted that magnet herein is the combination for including the magnet required for loudspeaker
Block magnet etc..
The application cleverly will set snak link on loudspeaking component, be attached using between snak link and magnet, not only
So that the positioning between magnet and loudspeaking component is more accurate, while avoid direct between magnet and the voice coil loudspeaker voice coil of loudspeaking component
Contact, while the mode that the snak link is engaged with occlusal crib realizes the more simple audio amplifier mode of production, avoids original
Positioning difficulty in the mode of production between magnet and voice coil loudspeaker voice coil, avoid original integrally formed cumbersome mode of production.
Specifically, the loudspeaking component includes being close to voice coil loudspeaker voice coil, bullet ripple, frame, cone and dust cap that magnet is set gradually.
In order that the connection obtained between occlusal crib and snak link is more stable：
Specifically, the width of the occlusal crib is more than the width of snak link；
Specifically, the occlusal crib includes protrusion support section, the first side and first being connected with protrusion support section
The second side of side connection, the undercut surfaces being connected with second side；
Specifically, it is additionally provided with adhesive layer between the protrusion support section and snak link；
Specifically, press-fit face is formed between the first side of the occlusal crib, second side and snak link.
Specifically, the snak link uses plastics.
In order to solve the problems, such as that the maintenance of later stage audio amplifier dismounting difficulty is big, specifically, the base is detachable by bolt
Formula is fixed in casing.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1. the application cleverly will set snak link on loudspeaking component, it is attached using between snak link and magnet, no
Only so that the positioning between magnet and loudspeaking component is more accurate, while avoid straight between magnet and the voice coil loudspeaker voice coil of loudspeaking component
Contact, while the mode that the snak link is engaged with occlusal crib realizes the more simple audio amplifier mode of production, avoids original
There is the positioning difficulty between magnet and voice coil loudspeaker voice coil in the mode of production, avoid original integrally formed cumbersome mode of production, together
When can keep the tonequality more stablized；
2. the width of occlusal crib is more than to the width of snak link in the application, and between protrusion support section and snak link
Adhesive layer is additionally provided with, improves occlusal crib and snak link connective stability；
3. herein described base is fixed in casing by the way that bolt is detachable, the maintenance dismounting for solving later stage audio amplifier is difficult
Spend the problem of big so that the problem of dismounting difficulty in later stage is small.
