CN2296105Y - Framed vibration speaker - Google Patents

Abstract

The utility model relates to a frame type vibrating membrane loudspeaker belonging to a sounding device. Because the structure of a vibrating membrane of an existing loudspeaker is influenced by dividing vibration, various kinds of distortion exist, and the effect on sound quality is not ideal. The aim of the utility model is to provide the vibrating membrane loudspeaker provided with a rigidity frame above a conical vibrating membrane, or below a flat plate membrane, or below a ball top membrane. The utility model inhibits transverse waves in the membrane and dividing vibration, solves the problem of various kinds of distortion, and has good frequency response, and clear and pure sound quality. The technology leads a single membrane full band loudspeaker to be realized, and the structure of the utility model is simple.

Description

Skeleton vibrating membrane loud speaker

The utility model relates to the improvement of loud speaker, and especially skeleton vibrating membrane loud speaker belongs to microphone device.

Awl benzvalene form vibrating membrane or flat sheet membrane, ball teleblem are widely applied because of its advantage is more in the loud speaker at present.But vibrating membrane is cut apart vibration effect because of its structure, mostly produces various distortions, and acoustical quality is undesirable.On vibrating membrane, done a large amount of improvement for improving the tonequality people, from cone, adding various fiber materials, but still can not increase substantially tonequality, reduce various distortions to combined type material and diamond spraying etc.

The purpose of this utility model provides a kind of skeleton vibrating membrane loud speaker that installs rigid backbone additional and form on the vibrating membrane of existing loud speaker, make vibrating membrane reach desirable stiff piston effect, suppressed the generation of various distortions, make frequency response more smooth, strengthened the radiation of bass, improved alt definition, acoustical quality is even more ideal.

The technical solution of the utility model is the structure that does not change existing loud speaker, be characterized in the vibrating membrane upper edge of this loud speaker vibrating membrane radial direction self-excited oscillation film outer rim to the vibrating membrane inner edge, evenly be fixed with at least two thin slice shape rigid backbone perpendicular to vibrating membrane face direction, each rigid backbone intersects at vibrating membrane central axis place and interconnects, and makes vibrating membrane become rigid body and is operated in the loud speaker.

The vibrating membrane that technical solutions of the utility model are suitable for comprises tapered vibrating membrane, flat sheet membrane or ball teleblem, and rigid backbone can be installed in the face top of tapered vibrating membrane, the face bottom of flat sheet membrane or the face bottom of ball teleblem.

Be connected with vibrating membrane in rigid backbone on the rigid backbone edge of side and have the installation burr, will install during assembling and fix with glue after burr inserts the vibrating membrane face.

The utility model enforcement simple in structure, easy, effect especially obviously, have greatly improved the acoustical quality of loud speaker.

Accompanying drawing 1 is the structural representation after the utility model is used for a kind of embodiment in the vibration of tapered film and cuts open.Fig. 2 is the vertical view of Fig. 1.Among the figure: 1 vibrating membrane, 2 basin framves, 3 upper guide plates, 4 bottom guides, 5 voice coil loudspeaker voice coils, 6 magnet steel, 7 locating branch slices, 8 rigid backbone, 9 dust covers, 10 install burr, 11 vibrating membrane inner edges, 12 vibrating membrane outer rims, 13 vibrating membranes neck ring, 14 glue.

Below in conjunction with accompanying drawing the utility model is further described.

The overall structure of this loud speaker is identical with existing loud speaker, be characterized in vibrating membrane (1) face upper edge vibrating membrane radial direction from vibrating membrane inner edge (10) to vibrating membrane outer rim (11), perpendicular to sticking several rigid backbone (8) that are equipped with of face, rigid backbone intersects at vibrating membrane central axis 14 places and is bonding mutually, is operated in the loud speaker after making vibrating membrane become the piston type rigid body.

In the present embodiment, be made of four rigid backbone, evenly distributing is fixed on the vibrating membrane face, and rigid backbone is to be made of certain thickness trapezoidal sheet metal, makes sharp jagged installation burr (10) in rigid backbone with the side that the vibration face is connected.During assembling, make rigid backbone along the vibrating membrane warp direction, cement the installation burr insertion vibrating membrane blended rubber of rigid backbone one side fixing, the rigid backbone opposite side also is glued after intersect at vibrating membrane central axis place, like this, because the rigidity effect of rigid backbone becomes one vibrating membrane, and is strong as having increased skeleton for vibrating membrane.

The utility model is simple in structure, implements need not change the structure of existing loud speaker easily.Can after finishing, the loud speaker manufacture craft install rigid backbone again additional.

The effect of rigid backbone has been equivalent to improve the rigidity of vibrating membrane face in this skeleton vibrating membrane, and the shear wave transmission is inhibited, and has eliminated in the existing vibrating membrane work and has cut apart the various harmful effects that vibration causes because of face.This practice is applicable to the vibrating membrane of various materials and different shape, makes the vibration work with various frequency of sound wave signals simultaneously of whole face.

Parameters such as the material of rigid backbone, shape, size, specification, design is determined according to factors such as diaphragm diameter size, shapes.

The utility model designer has implemented the skeleton vibrating membrane loud speaker of various high, medium and low sounds, for example: on the woofer of 6 inch, install the rigid backbone that the lead alloy of four 0.5 millimeters thick is made additional, obtain highly desirable acoustical quality.Enforcement of the present utility model, the loud speaker of low-grade with making, low price becomes the elaboration of high-fidelity, will make single vibrating diaphragm full range speaker accomplished.

Claims (3)

1, a kind of skeleton its overall structure of vibrating membrane loud speaker is identical with existing loud speaker, it is characterized in that: in the vibrating membrane upper edge of this loud speaker vibrating membrane radial direction self-excited oscillation film outer rim to the vibrating membrane inner edge, evenly be fixed with at least two thin slice shape rigid backbone perpendicular to vibrating membrane face direction, each rigid backbone intersects at vibrating membrane central axis place and interconnects, and makes vibrating membrane become rigid body and is operated in the loud speaker.
