Mainboard upper cover of electronic equipment, its manufacturing method and electronic equipment

Abstract

The invention discloses a mainboard upper cover, its manufacturing method and electronic equipment. The mainboard upper cover has a decoration part and a sound outlet part connected to one side of the decoration part, and the sound outlet part includes a plurality of sound outlet holes. The manufacturing method of the upper cover of the main board is to firstly provide the forming mold of the upper cover of the main board, the forming die has the structures of the decoration part and the sound output part; and inject plastic into the forming die to form. Another manufacturing method is to firstly provide a structure with the decorative part and the sound outlet; set the structure into the molding mold of the main board cover; inject plastic into the molding mold, and the plastic will form the structure Formed by secondary overmolding. The present invention integrates the existing decorative cover of the receiver with the upper cover of the main board to reduce the assembly process of the electronic equipment, avoid the risk of reliability during assembly, and increase the sound volume of the electronic equipment.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a main board upper cover of an electronic equipment, a manufacturing method thereof and the electronic equipment. Background technique [0002] Consumers' pursuit of products is becoming more and more extreme, and the demand for sound effects of electronic devices (especially mobile phones) is getting higher and higher. We hope that the space design of the sound cavity channel will be large enough. The contradiction is that the pursuit of a full screen requires The exposed structural member area should be kept as small as possible. [0003] At present, electronic equipment is assembled with a receiver decorative cover on the decorative part and the sound output part of the main board cover. The receiver decorative cover is installed on the main board cover through assembly, which makes the assembly process of electronic equipment complicated and prone to reliability ...
