Embodiment Construction

[0021] As shown in the figure, the photocell signal output terminal is connected to the CPU, the CPU is SM8440, and the CPU signal output terminal is connected to the audio power control unit. The audio power supply control unit has a triode, the base of the triode is connected to the CPU signal output terminal, and the output signal of the emitter of the triode controls the audio power supply to be connected.

[0022] The CPU communicates with the movement. The movement uses Xinhua CLC-01. The movement includes a transmission motor, a brake switch, an active motor, and an audio decoding chip. The signal output terminal of the audio decoding chip in the movement is connected to the sound control module, and the sound control module is composed of a volume control chip and an audio power amplifier, wherein the signal input terminal of the audio power amplifier is connected to the movement, the signal input terminal of the volume control chip is connected to the CPU, and the audi...

Abstract

The invention relates to a method and a device for activating automobile sound, which can effectively activating an automobile sound system. The method comprises the following steps: communicating CPU with a core, and connecting a core-signal input end to a sound control module. The invention is characterized in that a memory power source always in the electrified state is installed; the memory power source is connected with photocells capable of identifying discs; and after identifying the discs, the photocells output signals to the CPU, and the CPU outputs control signals to switch on the power source of the sound system, so that the sound system is in the ON state.

Description

technical field [0001] The invention relates to a car audio wake-up method and device. Background technique [0002] Present automobile is generally all equipped with car audio device, in the car audio device with movement, has adopted two kinds of modes to realize automatically sucking dish, reading dish. One is the mechanical type, which adopts the disc touch method to transmit information to realize automatic disc suction; the other is the light-sensitive type, which adopts the photoelectric cell induction method to realize the functions of automatic disc suction and disc reading. These two methods must be in the normal power-on state to realize the above functions. [0003] As more and more cars enter ordinary families, the needs of users are becoming more and more diverse. The automatic wake-up function of car audio has become an additional function that has won the favor of more consumers. The functions of the existing car audio system cannot meet the needs of users,...
