Description
Technical Field
The utility model relates to a loudspeaker structure, in particular to a connecting structure of a voice coil and a damper and a loudspeaker.
Background
The prior loudspeaker is generally provided with a basin frame, a magnet, a voice coil, a cone, a damper and other structures. The spring wave is also called a baffle plate and a damper, and has a braking function and a center retaining function. The outer edge of the elastic wave is adhered to the support, the neck (inner ring) of the elastic wave is adhered to the neck of the voice coil and the drum paper, so that when the voice coil moves in the magnetic gap, the voice coil does not touch the iron sheet or the magnet, and the voice coil and the drum paper are correctly connected to keep the center, so that the voice coil is also called as a center retainer, the inner ring of the elastic wave and the voice coil are generally fixed through glue, and the outer ring of the elastic wave is fixed on the basin frame. The existing elastic wave only has one circle of inner ring abutted with the voice coil, when gluing is carried out, glue enters between the voice coil and the cone for bonding, and the connection strength is weaker.
In the prior art, some devices for enhancing the connection strength of a damper and a voice coil exist, for example, patent with an authorized bulletin number of CN212910018U discloses a damper reinforcing ring of a speaker, which is convenient to assemble, and comprises a support ring body and a switching ring body, wherein the shape of the inner edge of the support ring body is matched with the shape of an adapting hole of the damper, the switching ring body extends obliquely upwards from the joint of the top surface and the outer ring surface of the support ring body, a positioning ring groove is formed on the bottom surface of the support ring body, the positioning ring groove extends along the circumferential direction of the support ring body, the shape of the positioning ring groove is matched with the shape of the adapting end of the voice coil, the edge of the adapting end of the voice coil is provided with a positioning rib, the diameter of the positioning rib is larger than the diameter of the adapting hole, and when the adapting end of the voice coil is assembled in the adapting hole, the positioning rib is embedded in the positioning ring groove;
the reinforcing ring is provided with the glue storage ring groove on the inner ring surface of the adapter ring body, so that the loss of the glue solution connected between the inner ring surface of the adapter ring body and the outer wall of the elastic wave can be avoided; but the above patents have more functions of strengthening the strength of the elastic wave; meanwhile, the supporting ring body and the adapter ring body are integrally formed by rubber injection molding, and the performance of the sound box is affected due to overlarge counterweight.
Therefore, there is a need for an improvement in such a structure to overcome the above-mentioned drawbacks.
Disclosure of Invention
The utility model aims to provide a connecting structure of a voice coil and a damper and a loudspeaker, so as to solve the problems in the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
the connecting structure of the voice coil and the elastic wave comprises a supporting ring, wherein the whole supporting ring is made of paper, and comprises an integrally formed annular part and a conical ring part, the annular part is sleeved on the voice coil, and the conical ring part is abutted to the bottom of an inner ring of the elastic wave; the included angle a between the outer wall of the conical ring part and the outer wall of the circular ring part is 130-135 degrees.
Further, the included angle a between the outer wall of the conical ring part and the outer wall of the circular ring part is 132.6 degrees.
Further, the voice coil comprises a framework and a coil formed by enameled wires, wherein the annular part is sleeved at the upper end of the framework, and the inner wall of the annular part is tightly attached to the outer wall of the framework of the voice coil.
Further, the inner diameter of the circular ring part is identical with or slightly larger than the outer diameter of the framework, and the outer diameter of the circular ring part is smaller than the outer diameter of the coil.
Further, the thickness of the backing ring is 0.7mm.
Further, the loudspeaker comprises a connecting structure of the voice coil and the elastic wave.
Compared with the prior art, the utility model has the beneficial effects that: when the voice coil assembly is used, as the inner wall of the circular ring part is tightly attached to the outer wall of the framework, glue is difficult to flow down between the circular ring part and the framework, most of the glue can be temporarily stored between the inner wall of the circular ring part and the outer wall of the framework until the glue is dried and solidified, and the connection strength between the elastic wave and the voice coil is increased;
the outer diameter of the circular ring part is smaller than the outer diameter of the coil, so that when the voice coil moves up and down in the magnetic gap, the supporting ring cannot strike the edge of the magnetic gap, namely, the supporting ring cannot influence the movement path of the voice coil;
the whole backing ring is paper, and weight is lighter, can not play very big influence to the performance of audio amplifier, fine maintenance original product's characteristic.
