Description

Multi-layer mirror structure for earphone Technical Field The utility model relates to a multi-layer mirror, in particular to a multi-layer mirror structure for an earphone. Background At present, a thousand layers of mirrors are often installed on the earmuff type earphone, and an infinitely-extending visual effect is generated through reflection and refraction of light rays. The patent document of China patent publication No. CN220821018U, entitled "a multi-layered mirror and a headphone using the same" discloses a multi-layered mirror, which comprises an outer transparent lens and an illuminating lamp plate arranged in the mirror body, wherein an inner transparent lens with a transparent pattern is arranged between the outer transparent lens and the illuminating lamp plate, a light reflection and refraction space is formed between the inner transparent lens and the outer transparent lens, light emitted by the illuminating lamp plate enters the inner transparent lens and the outer transparent lens from the transparent pattern to reflect light emission and refraction phenomena, and finally the light comes out from the outer transparent lens to bring visual effects of multilayer overlapping patterns to people. However, the applicant finds that although the above multi-layered mirror can produce a better visual effect, its structural design is not reasonable enough, and the structure of each accessory is not in a precise matching relationship, so that the relative positions of each component are inaccurate, the errors are larger, the occupied space is larger, the assembly working efficiency is lower, and the difference of the processed different finished products is larger, so that the light rays generated by different multi-layered mirrors are different, and the difference of the visual effects obtained by different individuals of the earphone provided with the multi-layered mirror is larger. Disclosure of utility model The utility model aims to provide a multi-layer mirror structure for an earphone, which is compact in structure, accurate in relative positions of all parts, easy to assemble and capable of generating a stable visual effect. The technical scheme adopted is as follows: a multi-layer mirror structure for an earphone is characterized by comprising a decorative cover plate, a semi-lens, a positioning middle frame, a single-sided mirror, a light guide piece and an LED lamp panel, wherein the LED lamp panel is fixed on the inner side surface of the light guide piece, the single-sided mirror is fixed on the outer side surface of the light guide piece, the light guide piece is inserted with the positioning middle frame, the semi-lens is arranged on the front side of the positioning middle frame, and the decorative cover plate is clamped with the positioning middle frame. The components are assembled to form a complete multi-layer mirror structure. The earphone with the multi-layer mirror structure can be manufactured by installing the multi-layer mirror structure into the shell of the earmuff type earphone. Because the multi-layer mirror structure can be independently processed and assembled, the working efficiency of assembly is high, and therefore the working efficiency of earphone processing can be greatly improved. The decorative cover plate comprises an annular main body and a plurality of buckles, wherein all the buckles are respectively arranged on the rear side face of the annular main body, clamping grooves which can be mutually buckled with the buckles are formed in the outer side wall of the positioning middle frame, the clamping grooves and the buckles are the same in number and correspond to each other one by one, and each buckle is buckled with the corresponding clamping groove. The decorative cover plate further comprises at least one positioning column, all the positioning columns are respectively arranged on the rear side face of the annular main body, first positioning grooves which can be mutually spliced with the positioning columns are formed in the outer side wall of the positioning middle frame, the first positioning grooves and the positioning columns are the same in number and correspond to each other one by one, and each positioning column is respectively spliced with the corresponding first positioning groove. The preferred scheme, light guide front surface outward flange has at least a slice inserted sheet, and the location center inside wall is equipped with light guide location step, opens on the light guide location step has at least one slot, and slot and inserted sheet are the same and one-to-one, and light guide is laid in the location center from the back to the front and the light guide supports light guide location step, and each inserted sheet is respectively with corresponding slot plug-in. More preferably, the outer side wall of the light guide member is provided with at least one second positioning groove, the inner side wall of the positioning middle frame i
