Description

Hollow double-folded ring composite paper cone

Technical Field

The utility model belongs to the technical field of the cone technique and specifically relates to a compound cone of fretwork type double folded ring.

Background

In the loudspeaker, after being connected with an audio signal, the voice coil can generate strong vibration in a magnetic field, the voice coil is fixed on the cone, the vibration of the voice coil drives the cone to vibrate simultaneously, and the cone vibrates to force air to vibrate, so that sound is produced. The existing cone has a complex structure and poor symmetry, which causes loudspeaker distortion.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: overcomes the defects in the prior art and provides a hollow double-folded-ring composite cone.

The utility model provides a technical scheme that its technical problem adopted is: a hollow-out type double-folded ring composite cone comprises an upper folded ring and a lower folded ring, wherein a cone body is clamped between the upper folded ring and the lower folded ring;

the upper folding ring comprises an upper inner ring and an upper outer ring which are arranged inside and outside, and an upper convex ring which is convex upwards is connected between the upper inner ring and the upper outer ring; the inner diameter and the outer diameter of the upper folding ring and the lower folding ring are consistent;

the downward folding ring comprises a lower inner ring and a lower outer ring which are arranged inside and outside, a downward convex ring which is convex downwards is connected between the upper inner ring and the lower outer ring, and through holes which are uniformly distributed are formed in the lower convex ring.

Furthermore, the upper inner ring and the lower inner ring are respectively glued on the upper surface and the lower surface of the mounting part of the cone body, and the upper outer ring and the lower outer ring are connected in a gluing mode.

Furthermore, the upward folding ring is an integrally formed rubber ring, a foam ring or a rubberized cloth ring.

Further, the downward folding ring is an integrally formed rubber ring, a foam ring or a rubberized cloth ring.

The utility model has the advantages that: the utility model discloses simple structure has following advantage:

(1) the upper and lower folding rings are arranged, so that the integral cone can vibrate up and down, higher symmetry is kept, the integral characteristic of the loudspeaker is improved, particularly distortion can be greatly improved, and pure sound is also well improved;

(2) the lower convex ring of the lower folded ring is provided with a through hole, the hollow design can reduce the air resistance of the closed air flow in the middle of the upper folded ring and the lower folded ring to the folded ring, the hollow can also reduce the weight of the lower folded ring, and the adverse effect on the sensitivity characteristic of the loudspeaker is avoided;

(3) the up-down folded ring is arranged, and the damping coefficient is increased, so that the traditional elastic wave structure can be cancelled, the design of the effective space of the loudspeaker is favorable, and the total height of the loudspeaker can be reduced;

(4) the utility model discloses increase the linear compliance's of cone scope, improved the power endurance performance of speaker.
