Example Embodiment

[0032] In order to achieve the above purpose, the present invention records the time from pressing the button of the wired earphone to releasing it; by comparing the time length with a preset threshold value, the type of key corresponding to the time length is judged and recorded; Execute the corresponding function according to the recorded key type operated once or a combination of key types operated multiple times. In this way, at least one button is needed to control various complex functions of the wire-controlled earphone.

[0033] The connection circuit between the earphone line control circuit and the portable electronic device body in a preferred embodiment of the present invention, see figure 2 shown. The detection circuit of the wire-controlled earphone end only has an ordinary button K, which is connected to the input terminal of the interruption detection module in the detection circuit of the host through the earphone socket, and the output end of the interrupti...

Abstract

The invention discloses a portable electronic device and a wire-control method. The portable electronic device includes an earphone socket, a CPU and an interruption detecting module. During the wire-control process through a wire-control earphone, the CPU records the time from the press-down to release of the wire-control earphone key-press, compares the time length with the preset threshold to judge and record the type of the key-press corresponding to the time length, and performs corresponding functions according to the recorded type of key-press for one-time operation or the combination of key-press types for many times of operation. With the simple wire-control earphone provided by the invention, various control functions can be performed to the portable electronic device.

Description

technical field [0001] The invention relates to a wire control technology of a portable electronic device, in particular to a portable electronic device and a wire control realization method thereof. Background technique [0002] The popularity of portable electronic products brings great convenience to users' lives. Ease of use and a good man-machine communication interface are important indicators for evaluating the quality of portable products. [0003] In the prior art, wire control of the earphone is generally implemented through a dedicated serial interface, such as an inter-integrated circuit bus (I2C), or multi-line common key scanning. [0004] In the Chinese patent application with the application number 02117856.9 submitted by the applicant on May 23, 2002, a connection circuit between a wire-controlled earphone and a portable electronic device body through a dedicated serial interface is disclosed. See figure 1 As shown, it includes: buttons S1, S2, S3 and S4, ...
