Embodiment 1

[0034] Such as figure 1 As shown, a method for turning on and off a mobile device includes the following steps:

[0035] The digital microphone module detects the voice signal outside the mobile device;

[0036] Check the voice signal to determine whether it is a preset voiceprint feature, and if it is a preset voiceprint feature, send a verification success signal;

[0037] Determine whether the voice signal contains a specific keyword, identify whether the specific keyword is a power-on or power-off keyword, and if it is a power-on or power-off keyword, wake up or interrupt the CPU of the mobile device to start or shut down.

[0038] It also includes storing preset voiceprint features in the system of the mobile device, and the number of preset voiceprint features is at least one.

[0039] After the digital microphone module recognizes that the specific keyword is the power-on keyword, and before waking up the CPU of the mobile device to start the machine, it also includes...

Embodiment 2

[0044] Such as figure 2 As shown, a mobile device includes a digital microphone module, a central processing unit module, a power management module and a power supply module;

[0045] The digital microphone module is located inside the mobile device, and the digital microphone module is independent of the CPU of the mobile device and is powered separately;

[0046] The digital microphone module can be a MEMS digital microphone module, which is composed of a MEMS micro-capacitance sensor, a micro-integrated conversion circuit (ie, an amplifier), an acoustic cavity, and an RF anti-noise circuit. The MEMS micro-capacitor head part includes a silicon diaphragm and a silicon On the back pole, the silicon diaphragm can directly transmit the received voice signal to the micro-integrated conversion circuit through the MEMS microcapacitive sensor. The micro-integrated conversion circuit can convert and amplify the high-impedance voice signal into a low-impedance voice signal, and at t...

Embodiment 3

[0050] The digital microphone module includes

[0051] a voice detection unit, configured to detect a voice signal outside the mobile device;

[0052] The voiceprint recognition unit is used to verify the voice signal and judge whether it is a preset voiceprint feature;

[0053] A keyword recognition unit is used to judge whether the voice signal contains a specific keyword, and to identify whether the specific keyword is a power-on or power-off keyword;

[0054] A wake-up unit, configured to send a control signal for waking up the CPU of the mobile device to start the machine;

[0055] The interrupt unit is used to send a control signal for interrupting the CPU of the mobile device to shut down.

[0056] The wake-up unit is also used to determine whether the CPU of the mobile device is in an off state before waking up the CPU of the mobile device to start the machine.

[0057] The interrupt unit is also used to judge whether the CPU of the mobile device is in the power-on ...

Abstract

The present invention provides a power-on / off method for a mobile device. The method comprises the following steps: a digital microphone module detecting a voice signal outside of a mobile device; verifying the voice signal, determining whether the voice signal has a preset fingerprint feature, and if yes, sending out a verification success signal; and determining whether the voice signal contains a specific keyword, identifying whether the specific keyword is a power-on or power-off keyword, and if yes, awakening or interrupting a CPU of the mobile device to power on or power off. The present invention further provides a mobile device. The power-on or power-off of the mobile device is controlled in a voice manner, so that the power-on / off key is unnecessary to set on the mobile device, the problem that power-on / off cannot be normally performed due to a key failure is effectively solved, and the operation is made more convenient; moreover, the effect of confidentiality is achieved, and due to omission of the power-on / off key, the structural design can be simplified and the appearance of products can be beautified, which boosts miniaturization of mobile devices.

Description

technical field [0001] The invention relates to the technical field of mobile equipment, in particular to a mobile equipment and a method for turning it on and off. Background technique [0002] At present, various mobile devices such as smartphones and tablets are used more and more widely. In practical applications, the power-on or power-off of various mobile devices such as smartphones and tablet computers is basically realized by the user pressing the power-on / off buttons of these mobile devices for a long time. The way of switching on and off the mobile device has the defect of button failure caused by poor assembly contact or foreign matter entering the gap. At the same time, the existence of the switch button also hinders the miniaturization of the mobile device. Contents of the invention [0003] (1) Solved technical problems [0004] In order to solve the above technical problems, the present invention provides a mobile device and a power-on / off method, which ef...
