Embodiment Construction

[0049] Please refer to Figure 1A , Figure 1A is a schematic diagram of an electronic device according to an embodiment of the present invention. The electronic device 100 includes a speaker SPK1 , a sound signal processor 111 and an application processor 120 , wherein the speaker SPK is coupled to the sound signal processor 111 , and the sound signal processor 111 is coupled to the application processor 120 .

[0050] The sound signal processor 111 is used to sense the variation of the acoustic condition (acoustic condition) of the speaker SPK, in other words, the sound signal processor 111 is used to sense the acoustic impedance (acoustic impedance) of the speaker SPK, and generate a corresponding sensing signal. In detail, for example, when performing the acoustic impedance sensing operation, the acoustic signal processor 111 may transmit a detection signal to drive the speaker SPK. Moreover, the speaker SPK has a speaker opening, and when the speaker opening is blocked, ...

Abstract

An electronic device and method for activating specific functions, the electronic device includes a speaker, a sound signal processor and an application processor. The sound signal processor can sense a change in the acoustic condition of the speaker, and the application processor can generate a logic high or low signal in response to the sensed change in the acoustic condition, interpret the logic high or low signal as a control signal, and Execute instructions corresponding to control signals.

Description

technical field [0001] The present invention relates to a method for activating a specific function of an electronic device, and in particular to a method for activating a specific function by detecting the acoustic resistance of at least one speaker. Background technique [0002] Today, mobile electronic devices are widely used. In order to provide a convenient operation interface, the touch panel is the most popular structure. By using the touch sensor in the touch device, the sensing area can be limited by the touch panel. In this way, the virtual key will occupy the space of the display area, that is to say, in the conventional technology, the size and cost of the mobile device will increase due to the increase of the touch sensing area. Contents of the invention [0003] The invention provides an electronic device and a method for activating a specific function, which can improve the convenience of the electronic device. [0004] The invention provides an electroni...
