Abstract

The invention discloses an active sound box, relating to the technical field of household appliances. The active sound box comprises a Bluetooth power amplifier unit, an electron tube analog amplification unit, an AD conversion unit, a digital amplification unit and a loudspeaker, the output end of the Bluetooth power amplifier unit is connected with the input end of the electronic tube analog amplification unit; the output end of the electronic tube analog amplification unit is connected with the input end of the AD conversion unit; the output end of the AD conversion unit is connected with the input end of the digital amplification unit; the output end of the digital amplification unit is connected with the input end of the loudspeaker; an audio signal is amplified in a mode that the electronic tube analog amplification unit and the digital amplification unit are combined, an active sound box with softer tone and more charm is achieved, in addition, a sound source device can be connected in a wireless mode through the Bluetooth power amplification unit, and the active sound box is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to an active sound box. Background technique [0002] Active speaker refers to a device that can convert audio signals into sound. Generally speaking, it refers to the active speaker main box or subwoofer box with its own power amplifier. After the audio signal is amplified, it is returned by the active speaker itself. Let out the sound to make it louder. [0003] Most of the existing active speakers use ordinary operational amplifiers, and the sound quality is relatively ordinary. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide an active speaker with better sound quality. [0005] The technical scheme adopted in the present invention is: [0006] An active speaker, comprising: a bluetooth power amplifier unit...
