The utility model content
The purpose of this utility model provides a kind of ripple and bonding firm loud speaker of voice coil loudspeaker voice coil of playing.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of loud speaker, the vibrating diaphragm that it comprises outstanding limit that the bottom is provided with the framework of microscler cell body, fixes with the edge of opening of described cell body, fix between described framework and described outstanding limit and with described outstanding limit, play ripple, the voice coil loudspeaker voice coil fixed with described bullet phase of wave, be positioned at two terminal boards of described frame roof and be positioned at magnetic circuit system on the described framework, described bullet ripple is between voice coil loudspeaker voice coil and framework, described bullet ripple is provided with kink, and this kink is adhesively fixed mutually with described voice coil loudspeaker voice coil.
According to the utility model, preferably, described bullet ripple comprises two side portion that are parallel to each other, the rectangle fixed part between two described side portion, connects the excessive connecting portion of described side portion and described fixed part, described two side portion and described framework fix, and two long legs of described rectangle fixed part make progress or are bent to form described kink downwards.
Preferably, Open Side Down for described cell body, and the bottom of described cell body is provided with the rectangle framework, the inner rectangular through holes that forms of described rectangle framework, and described voice coil loudspeaker voice coil passes described through hole.Further, two minor faces of described rectangle framework are provided with the extension of " eight " font of a pair of being, and the plane at the upper surface place of described extension is positioned at the top on the plane at described framework place.
Preferably, described two terminal boards lay respectively on the described extension on the opposite external side inclined-plane.
Preferably, the edge of opening of described outstanding limit outward flange and described cell body fixes, and the inward flange on described outstanding limit and described vibrating diaphragm fix.
The beneficial effects of the utility model are: by adding kink on the bullet ripple in the prior art, be used for mutually bondingly with voice coil loudspeaker voice coil, increased the bond area that plays ripple and voice coil loudspeaker voice coil, thereby improved adhesive strength, prolonged the useful life of loud speaker.
