Abstract

The utility model relates to a noise coil framework with shoulder ring. The utility model comprises a noise framework 1 and a shoulder ring 2 positioned in upper part of outer wall of the noise framework; a fixed ring 3 is positioned on the shoulder ring 2; a fixed ring is provided with an opening 4 which is separated with the same intervals; the utility model also comprises a ring-shaped tightening sheet 5 which can be sleeved out of the framework; inner ring of the tightening sheet is provided with an opening 6 which is matched with the opening 4 of the fixed ring 3. When the noise framework is connected with the centering supporting sheet or the noise basin, the inner edge of the centering supporting sheet 7 or the small end of the noise basin 8 is stuck with the surface of the shoulder ring 2; the tightening sheet can press the noise basin or the centering supporting sheet. The utility model enhances the combining stability of the centering supporting sheet with the noise basin or the noise framework; and the utility model can reduce or remove the phenomena that the centering supporting sheet and the noise basin separate with the noise framework in vibration process.

Description

The speech coil framework that the shoulder ring is arranged

(1) technical field:

The utility model relates to a kind of structure of loudspeaker voice coil skeleton.

(2) background technology:

Speech coil framework is parts of loudspeaker voice coil, just becomes voice coil loudspeaker voice coil after the bottom of speech coil framework coils, and coil adopts the high temperature insulation enamelled wire, is bonded on the speech coil framework with glue.The centring disk of loud speaker and sound basin then fasten with glue on the top of voice coil loudspeaker voice coil.When the voice signal electric current flow through in coil, voice coil loudspeaker voice coil was subjected to the effect of magnetic field force and vibrates, and the sound basin that promotion is attached thereto makes it to vibrate together, sounds.Speech coil framework generally adopts materials such as paper, engineering plastics, aluminium to make.Can generate heat during voice coil loudspeaker voice coil work.The voice coil loudspeaker voice coil of powerful loud speaker, when working under high-power input, coil will produce a large amount of Joule heats at short notice.For can adopting the aluminum alloy materials of good heat conductivity or other metal material, the temperature that reduces the voice coil loudspeaker voice coil coil makes.But this kind structure, a large amount of heats on the coil can be delivered to the junction of speech coil framework and centring disk and sound basin by skeleton, make bonded adhesives softening, weakened the intensity of abutting edge, even centring disk and sound basin are separated with speech coil framework in vibration processes.

(3) summary of the invention:

The utility model proposes a kind of structure of speech coil framework, can increase the fastness that combines of centring disk and sound basin and speech coil framework, reduce or eliminate the phenomenon that centring disk and sound basin separate with speech coil framework in vibration processes.

This speech coil framework that shoulder ring is arranged comprises a speech coil framework, on the top of the outer wall of speech coil framework one shoulder ring is arranged.

When this speech coil framework that has shoulder to encircle is connected with centring disk or sound basin, the interior edge of centring disk or the small end of sound basin are pasted together mutually with the plane of shoulder ring, changed the connected mode of speech coil framework and centring disk or sound basin, the junction is subjected to force direction when having changed the sounding vibration, increased the fastness that combines of centring disk and sound basin and speech coil framework, can reduce or eliminate the phenomenon that centring disk and sound basin separate with speech coil framework in vibration processes.

(4) description of drawings:

Accompanying drawing 1 is this basic block diagram that the speech coil framework of shoulder ring is arranged;

Accompanying drawing 2 is for having increased the structure chart that the speech coil framework of takeing on ring is arranged of retainer ring;

Accompanying drawing 3 is the structure chart of connecting plate;

Accompanying drawing 4 is the schematic diagram of existing speech coil framework and sound basin, centring disk connected mode;

The schematic diagram that accompanying drawing 5 is connected with sound basin, centring disk for the speech coil framework that the shoulder ring is arranged;

The schematic diagram that accompanying drawing 6 is connected with sound basin, centring disk for the another kind of speech coil framework that has shoulder to encircle;

Another schematic diagram that accompanying drawing 7 is connected with centring disk and sound basin for the speech coil framework that the shoulder ring is arranged.

(5) embodiment:

As shown in Figure 1, this speech coil framework that shoulder ring is arranged comprises speech coil framework 1, on the top of the outer wall of speech coil framework one shoulder ring 2 is arranged.

As shown in Figure 5, when this speech coil framework that has shoulder to encircle is connected with centring disk or sound basin, the interior edge of centring disk 7 or the small end of sound basin 8 are pasted together mutually with the plane of shoulder ring 2.Compare with the connected mode of sound basin, centring disk with existing speech coil framework shown in Figure 4, the junction is subjected to force direction when having changed the sounding vibration, increased the fastness that combines of centring disk and sound basin and speech coil framework, can reduce or eliminate the phenomenon that centring disk and sound basin separate with speech coil framework in vibration processes.

As shown in Figure 2, on the outer wall of the speech coil framework 1 of this speech coil framework that shoulder ring arranged, a retainer ring 3 can also be arranged above described shoulder ring 2, five equilibrium spaced apertures 4 is arranged on the retainer ring, it also can comprise the connecting plate 5 of the annular that a be enclosed within speech coil framework as shown in Figure 3 is outer, the inner ring of connecting plate have with described retainer ring 3 on opening 4 corresponding breach 6.

When the above-mentioned this speech coil framework that has shoulder to encircle was connected with sound basin and centring disk, as shown in Figure 6, the interior edge of centring disk 7 or the small end of sound basin 8 were pasted together mutually with the plane of shoulder ring 2, compress connecting plate 5 above.Breach 6 on the connecting plate and the opening 4 on the retainer ring are to be used for making retainer ring 6 to pass from the inside of connecting plate 5.After connecting plate enters below the retainer ring,, sound basin or centring disk can be compressed angle of its rotation.Be bonding to glue between retainer ring 3, connecting plate 5, sound basin 8, centring disk 7 and the shoulder ring 2.This structure can further increase the fastness that is connected of centring disk and sound basin and speech coil framework.

As shown in Figure 7, this have the retainer ring 3 on the speech coil framework of takeing on ring can have more than two, is three among the figure, and described connecting plate 5 also can have more than two, among the figure is three.The quantity of retainer ring and connecting plate can be when being connected centring disk and sound basin actual needs and determine.

This have the speech coil framework of shoulder ring to make of engineering plastics or metal.As shown in Figure 7, can also respectively there be a rib 10,11 in the last bottom of voice coil loudspeaker voice coil coil 9, is used for preventing the diffusing circle of voice coil loudspeaker voice coil.
