Abstract

The utility model discloses a voice coil lead wire and vibrating diaphragm fixing structure, which aims to provide a fixing structure with reliable lead wire connection and long service life. At least three bonding points where the lead wire is bonded with vibrating diaphragm is formed on the lead wire from the root of a voice coil lead wire to the vibrating diaphragm. The fixing structure is characterized in that the first bonding point is at the root of the voice coil lead wire, with a size of about 3-4 mm, and the tangential distance between the lead wire and the voice coil is required to be 1-2 mm; a circular arc is formed on the lead wire in the leading-out direction and bent in the corrugated ring of the vibrating diaphragm along the corrugated ring, and the second bonding point is formed in the corrugated ring of the vibrating diaphragm; the lead wire is led out of the corrugated ring of the vibrating diaphragm, the leading-out direction thereof conforms to the normal line of the circular arc of the vibrating diaphragm at the leading-out point, and the third bonding point is formed at the edge of the vibrating diaphragm. The fixing structure is characterized in that phenomena such as pull and break of the lead wire at the root can not happen, suspension of the lead wire and stress during vibration can be reduced, wire brake can be avoided, therefore, the percent of pass of the product can be greatly improved and the service life thereof can be greatly prolonged.

Description

The structure that voice coil leads and vibrating diaphragm are fixing

Technical field

The utility model relates to the structure of loud speaker or receiver, relates in particular to the fixing structure of a kind of voice coil leads and vibrating diaphragm.

Background technology

Loud speaker be with voice coil loudspeaker voice coil that vibrating membrane is connected in vibration takes place behind the input audio signal and drive the vibrating membrane motion and sounding in magnetic field, on the vibrating membrane that directly bonds for the lead-in wire of the less common voice coil loudspeaker voice coil of loud speaker.The operation principle of receiver is similar to loud speaker, they are when work, and vibrating membrane is vibrating always, and lead-in wire also is in frequent motion state, many loud speakers do not cause lead-in wire to break or pull because lead-in wire fixes, and have shortened the useful life of loud speaker or receiver.

The utility model content

The purpose of this utility model provides a kind of the lead-in wire and connects voice coil leads and the fixing structure of vibrating diaphragm reliable, long service life.

In order to reach above-mentioned requirements, the technical solution of the utility model is: have at least from the voice coil leads root to the lead-in wire that goes out vibrating diaphragm three with the bonding point of vibrating diaphragm bonding, the bonding point that it is characterized in that first place is at the voice coil leads root, about 3-4mm is big for bonding point, and requiring lead-in wire and voice coil loudspeaker voice coil, tangent distance A is arranged is 1-2mm; Lead-in wire is along the CSC film ring bending in the vibrating diaphragm ring of outlet direction bent arc, and the bonding point at second place is in the vibrating diaphragm ring; Lead-in wire is drawn in the vibrating diaphragm ring, and outlet direction is consistent with the normal of the vibrating diaphragm circular arc at place, leading point, and the bonding point at the 3rd place is at the vibrating diaphragm edge.

The solidus structure main distinction and the advantage of structure that above-mentioned voice coil leads and vibrating diaphragm are fixing and routine are:

1, the voice coil leads root requires tangent line, can reduce the stressed of lead-in wire root like this, and the vibration that the root lead-in wire can not occur is pulled, broken string etc.;

2, voice coil leads is all fixed along the vibrating diaphragm ring, in suspension and when vibration that can reduce lead-in wire, are stressed, can improve the qualification rate of product greatly;

3, edge lead-in wire is drawn and fix from the normal direction of the vibrating diaphragm circular arc of leading point, can reduce stressed when vibrating, avoids breaking.

Description of drawings

Fig. 1 is voice coil leads and the fixing structural representation of vibrating diaphragm.

Wherein: 1, voice coil leads root; 2, vibrating diaphragm; 3, lead-in wire; 4, the bonding point at first place; 5, voice coil loudspeaker voice coil; 6, vibrating diaphragm ring; 7, the bonding point at second place; 8, leading point; 9, the bonding point at the 3rd place; 10, everywhere the bonding point.

Embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 1 is voice coil leads and the fixing structural representation of vibrating diaphragm.As seen from the figure, it has everywhere the bonding point with vibrating diaphragm 2 bondings from voice coil leads root 1 to the lead-in wire 3 that goes out vibrating diaphragm 2, the bonding point 4 at first place is big at bonding point 4 about 3-4mm at voice coil leads root 1, the first place, and requiring lead-in wire 3 and voice coil loudspeaker voice coil 5, tangent distance A is arranged is 1-2mm; Lead-in wire 3 is along CSC film ring 6 bendings in vibrating diaphragm ring 6 of outlet direction bent arc, and the bonding point 7 at second place is in vibrating diaphragm ring 6; Lead-in wire 3 is drawn in vibrating diaphragm ring 6, and outlet direction is consistent with the normal of vibrating diaphragm 2 circular arcs at 8 places, leading point, and the bonding point 9 at the 3rd place is at vibrating diaphragm 2 edges; Everywhere the bonding point 10 is on the lead-in wire 3 between the bonding point 7 at the bonding point 4 at first place and second place.The viscose glue that all bonding points are used is the high tenacity ebonite.

Claims

1, the fixing structure of voice coil leads and vibrating diaphragm, have at least from the voice coil leads root to the lead-in wire that goes out vibrating diaphragm three with the bonding point of vibrating diaphragm bonding, the bonding point that it is characterized in that first place is at the voice coil leads root, and about 3-4mm is big for bonding point, and requiring lead-in wire and voice coil loudspeaker voice coil, tangent distance A is arranged is 1-2mm; Lead-in wire is along the CSC film ring bending in the vibrating diaphragm ring of outlet direction bent arc, and the bonding point at second place is in the vibrating diaphragm ring; Lead-in wire is drawn in the vibrating diaphragm ring, and outlet direction is consistent with the normal of the vibrating diaphragm circular arc at place, leading point, and the bonding point at the 3rd place is at the vibrating diaphragm edge.
