The invention discloses portable electronic equipment with lost reminding function. The portable electronic equipment comprises a microphone, an amplifying circuit, an analog-digital converter, a central processing unit and an audio output circuit, wherein the microphone is used for picking up a voice-simulated signal; the amplifying circuit is connected with the microphone, receives a voice signal picked up by the microphone, and amplifies the voice signal; the analog-digital converter is connected with the amplifying circuit, receives the voice signal amplified by the amplifying circuit, and converts the voice signal into a group of digital signals with a pulse sequence; the central processing unit stores a reference voice signal, compares the digital signals with the reference voice signal, and outputs an operating instruction if matching; and the audio output circuit is connected with the central processing unit, and sounds after receiving the operating instruction.
Description
technical field [0001] The invention relates to a portable electronic device, in particular to a portable electronic device with a lost reminder function. Background technique [0002] At present, due to the technical maturity and perfection of mobile communication networks, portable electronic devices such as mobile phones and personal digital assistants (PDAs) have become the most important tools for people to communicate. However, due to the small and exquisite characteristics of portable electronic devices, users often forget where they are placed, and sometimes they cannot be found when they are urgently needed. Users will search the room for small objects such as mobile phones. Contents of the invention [0003] In view of the above, it is necessary to provide a portable electronic device with a lost reminder function. [0004] A portable electronic device with a lost reminder function, comprising: [0005] a microphone for picking up an analog voice signal; [00...
