Abstract

The utility model provides a loud-speaker with changeable voice diaphragms (voice coil). A yoke iron is sheathed with an upper frame which is connected with a voice diaphragm and a voice coil, the yoke iron is also covered by a combined gasket and a star-shaped elastic clamp is used for bunting and clamping each component of the utility model, and thus, the assembly of the utility model is completed. The utility model is characterized in that the yoke iron is respectively provided with opposite inner concave ring grooves which are accurately fixed on the flange of the upper frame, and so the voice coil and the voice diaphragm are arranged on the right middle part; the outer margins of the upper frame and the combined gasket are provided with a plurality of opposite star-shaped clamping grooves to cause the combined gasket, the voice diaphragm, the voice coil and the upper frame to be fixed accurately in specified positions of the yoke iron by the star-shaped elastic clamps. Thus the utility model achieves the purposes of cost reduction, improvement of the continuous usage ability of products, and quick change and assembly.

Description

Loud-speaker with changable diaphragm

Relevant a kind of replaceable sound film (voice coil loudspeaker voice coil) loud speaker of the utility model, be about traditional speaker combination mode being modified to binding washer with moulding, upper frame and yoke, wherein the yoke outer rim is provided with interior concave ring groove, and the upper frame lower end is provided with involutory with it flange, and have in order to the annular flange flange of sound film to be set in the upper frame inwall, in the upper frame outer rim and be provided with several opposite grooves, and the binding washer outer rim also is provided with number simultaneously relatively

Type Ka Gou, through by The holding of type elasticity is compressed to reach rapidly the purpose that combination easily changes the outfit by warp-wise.

Loud speaker is via mechanical energy conversion audio energy with electric energy, and be the hearing organ that media is communicated to people with the air, general its action principle of loud speaker is that the magnetic field space that formed by magnet is with coaxial manner, voice coil loudspeaker voice coil is disposed in its space, when voice coil loudspeaker voice coil passes to electric current, voice coil loudspeaker voice coil is promptly becoming vertical direction to be subjected to the effect of power with magnetic field and power supply, promptly utilize this strength to be fixed in sound film on the voice coil loudspeaker voice coil and produced sound wave thereupon doing axial moving up and down (producing vibration) sound equipment promptly takes place.

By general traditional loud speaker, not outer gummed of combination or pressing between its sound film and upper frame, in a single day damaged and the sound film takes place, can't produce and vibrate stably and when influencing tonequality, no matter be in manufacture process or consumer's use in, owing to can't take repairing again apart, therefore must abandon, so in view of this utility model is to provide a kind of replaceable sound film (voice coil loudspeaker voice coil) loadspeaker structure to make to be able between yoke and sound film (voice coil loudspeaker voice coil) accurately fix rapidly or change on the appropriate location.

The utility model is a scrobicular ring trough in the magnetic support outer rim is set up relatively respectively, and the sound film and the voice coil loudspeaker voice coil that make connection be located at upper frame just can accurately be fixed thereon, and the flange of upper frame and the set number of outer rim are relative

But type Ka Gou is mat more

Holding of type elasticity and binding washer are finished assembling rapidly and are changed.

It is as follows that existing conjunction with figs. embodiment describes contexture of the present utility model in detail:

Fig. 1 is the utility model constitutional diagram.

Fig. 2 is the utility model exploded view.

Fig. 3 is the utility model profile.

Figure number among the figure is described as follows:

(1) ... yoke (2) ... interior concave ring groove

(3) ... flange (3 ') ... flange (power end)

(4) ... upper frame (5) ... type Ka Gou

(6) ... sound film (7) ... binding washer

(8) ... the holding of type elasticity

Please cooperate parts explosion of the present utility model with reference to Fig. 2, and feature of the present utility model in its compound mode wherein, upper frame (4) lower surface relatively partly has additional the flange of vacating (3) (3 ') makes upper frame (4) place yoke (1) upper surface, and flange (3) and (3 ') just are positioned at the concave ring groove part of magnetic support (1), and use accurate fixedly upper frame (4) sound film (6) in set desired position, its middle pitch film (6) joins with voice coil loudspeaker voice coil system is located at upper frame (4), and making has slippage improperly when being unlikely processing procedure and loading and unloading.

Wherein the set number of outer rim of upper frame (4) is relative Type Ka Gou (5) and binding washer (7) are set

Type Ka Gou (5), its size just is enough to cooperate

Type elasticity holding (8), and can make to closing packing ring (7), upper frame (4) sound film (6) and yoke (1) in the unlikely generation slippage improperly of when assembling and the combination of can simple speed finishing sound film (6) and voice coil loudspeaker voice coil with change the outfit, and reach the accurate fixing and effect that changes the outfit, and colory product must be arranged and improve the continuous ability of using of product, the fraction defective of its product also will thereby subtract greatly again, and is minimized cost.

In sum, the replaceable sound film of the utility model (voice coil loudspeaker voice coil) loud speaker is the utility model and closing in practicality at first really, and can reach aforesaid intended purposes, can reach accurate processing procedure, reduce cost, cut the waste, improve the continuous effect of product with ability and simple quick change dress, its structure simple and easyly but can be brought into play very big effect, really is the novel products that is imbued with practical value.

Claims

A kind of replaceable sound film (voice coil loudspeaker voice coil) loud speaker is cover unification upper frame on yoke, between upper frame then connection establish sound film and voice coil loudspeaker voice coil, and lid with binding washer again so that ［ holding of type elasticity compresses engaging with each parts, thus combination;

It is characterized in that yoke establish respectively relatively in concave ring groove, concave ring groove just can accurately be fixed in upper frame and flange in making, and makes voice coil loudspeaker voice coil and sound film are positioned at correct mid portion, its upper frame and binding washer outer rim, it is relative to be provided with number
Type Ka Gou, but make just mat
The holding of type elasticity all accurately is fixed in both allocations of yoke with binding washer, sound film, voice coil loudspeaker voice coil and upper frame, and can reach and reduce cost, and that improves product is continuous with ability and change the outfit rapidly.
