Abstract

The invention discloses an automobile power amplifier system based on novel algorithm decoding frequency division. The system comprises a shell and a guide mechanism, wherein the side surface of the shell is provided with symmetrically distributed fixed frames, the side surface of the shell is provided with a connector penetrating through the fixed frames, and the guide mechanism comprises a slot,an accommodating groove, a convex block and an insertion block. An inserting groove is formed in the surface of the shell, a containing groove is formed in the end of the inserting groove, and an inserting block matched with the inserting groove is arranged on the fixing frame. The beneficial effects of the invention are that the guide mechanism is designed, and the insertion block, the insertiongroove, the accommodation groove and the protruding block are matched, thereby increasing the guide of the connection of the fixed frame and the housing, and enabling the fixing of the fixed frame and the housing to be quicker; through the designed transparent protective sleeve, the transparent protective sleeve is used for improving the protection on the connector; under the condition of the same impedance, the ratio of the rated power of the sound box to the rated power of the power amplifier is 1: 1.2-1.5, so the tone is brighter and more mellow, and the distortion rate is lower.

Description

technical field [0001] The invention belongs to the technical field of automobile power amplifiers, and in particular relates to an automobile power amplifier system based on novel algorithm decoding frequency division. Background technique [0002] The car power amplifier is the car power amplifier, which is used to amplify the power of car audio. Its task is to amplify the weak electrical signal from the source to drive the speaker to emit sound. To achieve the ideal vehicle effect. The power amplifier circuit is composed of a pre-voltage amplifier stage, a push stage, a power amplifier stage, a speaker, etc., and the pre-stage is a voltage amplifier stage. The last stage is the power amplification stage, which amplifies the signal sent by the pre-stage to obtain enough power to output to the speaker, and the boost stage is to provide the larger input signal source power required by the power output stage. [0003] The automotive power amplifier system for decoding frequ...
