Abstract

A shell comprises a substrate and a reinforcing layer formed on the inner surface of the substrate. The substrate comprises at least one body part, a plurality of metal sheets and a plurality of nonconductive isolation layers. The metal sheets and the isolation layers are arranged alternately, and the metal sheets are fixedly connected by the isolation layers. The at least one body part is fixedly connected through the isolation layers with a component formed by alternately arranging the metal sheets and the isolation layers. The invention further provides an electronic device employing the shell and a manufacturing method of the shell. According to the shell, the electronic device employing the shell and the manufacturing method of the shell, the metal sheets and the isolation layers are arranged alternately, and the binding force of the metal sheets, the isolation layers and the substrate is enhanced by the reinforcing layer. Therefore, signal shielding is avoided, the dimensional accuracy is ensured, and the appearance of the shell is not affected.

Description

technical field [0001] The invention relates to a casing, an electronic device using the casing and a manufacturing method of the casing. Background technique [0002] With the continuous progress and development of modern electronic technology, electronic devices have achieved corresponding development, and consumers have higher and higher requirements for product appearance. Due to the advantages of metal shells in terms of appearance, structural strength, heat dissipation effect, etc., more and more manufacturers design electronic devices with metal shells to meet the needs of consumers. However, the metal casing easily interferes with the reception and transmission of signals by the antenna disposed therein, resulting in poor performance of the antenna. To solve this problem, designers often cut the part of the metal shell close to the antenna into small pieces to achieve the effect of enhancing the signal. However, due to the small size of the metal piece, the small pi...
