Abstract:
The present invention disclose an apparatus for fastening a digital memory card, including a tray and a card holder, where the tray includes a first groove, configured to accommodate a first digital memory card; and a second groove, disposed perpendicular to the first groove and configured to accommodate a second digital memory card, where the first groove and the second groove have hollowed portions that partially overlap; and the card holder includes a first spring and a second spring, where when the tray is inserted into the card holder, the first spring and the second spring extrude from the hollowed portions. According to the present invention, an apparatus for fastening a digital memory card, which is compatible with a SIM card and an SD card, is implemented, thereby flexibly meeting user requirements of using different cards by using an apparatus for fastening a digital memory card without increasing layout space.
Abstract:
An antenna system includes a first antenna and a second antenna, where the first antenna and the second antenna are connected in parallel to an antenna feeding point, and a phase-shift apparatus is connected in series between the first antenna or the second antenna and the antenna feeding point, so that an imaginary part of impedance at the antenna feeding point is canceled out near a central frequency channel number. The antenna system provides an expansion in radio frequency bandwidth in free space and an increase in average efficiency.
Abstract:
An integrated structure of a metal housing and an antenna of an electronic apparatus, where the electronic apparatus includes the metal housing and an antenna structure, the antenna structure includes an antenna main body, at least one micro gap set is disposed on the metal housing, the at least one micro gap set includes micro gaps, the at least one micro gap set divides the metal housing to form at least one metal region, and the at least one metal region is connected to the antenna main body to serve as a radiating body of the antenna structure.
Abstract:
A tapping control method and a terminal, which relate to the communications field and can avoid frequent automatic setting of the terminal caused by an unconscious operation of a user, thereby implementing accurate operation control on the terminal and improving a capability of the terminal to interact with the user. A specific solution is as follows. The terminal detects a tapping trigger signal within a preset frequency range by using a shock sensor; after the tapping trigger signal is detected, identifies a tapping action type corresponding to the tapping trigger signal; acquires a tapping response event that matches the identified tapping action type; and executes the tapping response event. The present disclosure can be used in a process of operation control on the terminal.
