Abstract

The application discloses an audio signal processing device and a speaker. The audio signal processing device includes a digital signal processing module, an input module, an output module and a control module; the digital signal processing module is connected to the input module and the output module, and the control module is connected to the output module; the output module is composed of morethan two paths of output channels, and each path of output channel includes a power amplifier and a loudspeaker that are connected in series; the digital signal processing module is used to process areceived audio signal by using at least two different audio processing algorithms to obtain more than two paths of audio processing signals, and each path of audio processing signal corresponds to onepath of output channel; and the control module is used to control whether the power amplifier in each path of output channel works and control the magnification at work. The audio signal processing device provided by the application can implement various sound effects and improve the user experience.

Description

technical field [0001] The application belongs to the field of audio signal processing, and in particular relates to an audio signal processing device and a sound box. Background technique [0002] Usually the audio files downloaded by the user from the network are compressed audio files, and the audio signal recorded by the user into the terminal device through the microphone also contains a lot of noise. If the audio file downloaded from the network is played directly or the audio signal picked up by the microphone is directly Playing will affect the final playback sound effect and reduce the user experience. Therefore, in order to achieve better sound effects, an audio signal processing device has emerged as the times require. The audio signal processing device is used to process the input audio signal in advance using an audio processing algorithm before playing the audio, so as to restore the information lost in the compression process or Filter noise, etc. Commonly us...
