Abstract

The invention discloses a DSP power amplifier device based on Bluetooth playing, which comprises a box body structure, a loudspeaker, a base and a heat dissipation mechanism, and is characterized in that the box body structure is mounted at the top end of the base, mounting screws are arranged on both sides of the base, the loudspeaker is mounted at one end of the box body structure, and the heatdissipation mechanism is arranged at the bottom end of the box body structure. A Bluetooth module is mounted at the top end of the main board; through mobile phone pairing, lossless music in the mobile phone is played; through the Bluetooth module, the lossless music is sent to an automobile power amplifier for decoding and playing; the Bluetooth mode is combined with the DSP power amplifier to realize the ultra-low-cost automobile power amplifier device; high-quality music in a mobile phone is played through the digital Bluetooth module, real lossless playing is achieved through DSP processing, the cost is reduced, the installation mode is simplified, after-sales manpower and material resources are reduced, high-quality lossless playing is achieved, the product competitiveness is improved, and therefore the purpose of improving the tone quality of the device is achieved.

Description

technical field [0001] The invention relates to the technical field of car audio, in particular to a DSP power amplifier based on bluetooth playback. Background technique [0002] The power amplifier is referred to as the power amplifier, and generally refers to one of the most basic equipment in the audio system. At present, the DSP power amplifier of the passenger car is the 4-way audio source output from the central control navigation host. After processing by a dedicated audio processing chip, it is output through power amplification To play high-quality music effects to the speaker, but there are many problems or defects in the existing DSP power amplifier device: [0003] First, the sound quality of the traditional DSP power amplifier device is not good. The mainstream DSP power amplifier plays music through the central control navigation host, and then it is processed by the DSP power amplifier and then output to the speaker for playback, because the manufacturer of t...
