Linear control system, linear control device and linear control method of mobile equipment

Abstract

The invention provides a linear control system of mobile equipment, comprising the mobile equipment, a linear control device and two signal wires, wherein the linear control device comprises a conductive contact terminal and a contact device, and the contact device comprises a substrate layer, a contact layer, an insulating hollow layer and a contact terminal supporting layer; the contact terminal supporting layer is provided with movement loci along a plurality of directions; the contact layer is provided with a plurality of contacts corresponding to the movement loci; when moving along the movement locus with the any direction, the terminal on the contact terminal supporting layer can touch the corresponding contacts, so that electric pulse signals can be generated, and the numbers of the electric pulse signals generated along the movement loci with different directions are different from each other; one end of the signal wires is respectively connected with the contact terminal andthe contact layer, and the other end thereof is connected with the mobile equipment; and the electric pulse signals are transmitted by a processor of the mobile equipment. The invention can realize the linear control function through the processor of the mobile equipment by using the two signal wires to transmit the electric pulse signals with very low hardware and structure costs.

Description

technical field [0001] The invention relates to a mobile device wire control technology, in particular to a mobile device wire control system, a wire control device and a wire control method. Background technique [0002] With the application of mobile phones more and more widely, the use of wire-controlled earphones in mobile phones is also increasing. At present, to achieve complex control of portable mobile devices, it is usually through a dedicated serial interface and multiple control buttons. This wire control method needs to increase the microprocessor circuit, which increases power consumption and cost, and requires 4 wires (I2C communication, I2C communication, Power supply and digital ground), if you use a standard 5-pin or a structurally compatible extended 10-pin USB interface, and use the USB protocol to support the control protocol on the wire control, it is required that the wire control device itself supports the USB protocol (protocol stack and chip) so that...
