The invention discloses a multifunctional intelligent alarm clock sound device, comprising a master control MCU, a power amplifier circuit, a speaker as well as a channel selector switch, a decoder, a crystal oscillation circuit, an instruction receiving module and a display which are connected with the master control MCU; wherein the decoder is provided with an interface used for inputting a digital audio signal, the output terminal of the decoder is connected with the speaker by virtue of the channel selector switch and the power amplifier circuit, and the master control MCU controls the switching of the channel selector switch. The invention not only can realize the alarm clock reminding function of the traditional alarm clock, but also the interface used for inputting a digital audio signal is arranged on the decoder, the interface can receives digital audio signals input by mobile devices such as USB and an SD card, the master control MCU can control the decoder to select a groupof input digital audio signals as an alarm clock ring tone, thus the invention can receive digital audio signals on mobile devices, has more alarm clock ring tones which can be updated, is rich in content and has big choice.
Description
technical field [0001] The invention relates to a multifunctional intelligent alarm clock sound. Background technique [0002] The music alarm clock in the prior art mainly uses a single-chip microcomputer solution to store several alarm clock tones through programming and solidification, and the user can make limited choices to start the alarm clock tones from the set alarm clock signal. This solution has relatively limited storage space, cannot update the alarm clock tone, and requires the alarm clock tone to be short and the content monotonously repeated. Contents of the invention [0003] The invention provides a multi-functional intelligent alarm clock sound, which can not only serve as the alarm reminder function of the traditional alarm clock, but also update the alarm tone with rich content. [0004] Technical scheme of the present invention is: [0005] A multifunctional intelligent alarm clock audio system, comprising: a main control MCU, a power amplifier circ...
