Abstract

The invention belongs to the technical field of a speaker box control circuit, and in particular to a speaker box external charge current detection circuit and a speaker box. In the embodiment of the invention, the speaker box external charge current detection circuit is connected with a speaker box power amplifier and an external charge module respectively. As for the external charge function of the speaker box, the speaker box external charge current and switching are controlled on the one hand and the output power of the power amplifier and sound quality of the speaker box are controlled on the other hand, the normal enjoyment of music of a user is satisfied, and the needs of the user for emergency external charge are met.

Description

technical field [0001] The invention belongs to the technical field of sound box control circuits, in particular to a sound box external charging current detection circuit and the sound box. Background technique [0002] A speaker refers to a device that converts an audio signal into sound. In layman's terms, it refers to the built-in power amplifier in the main box of the speaker or the subwoofer box. After the audio signal is amplified, the sound is played back by the speaker itself to make the sound louder. [0003] Some of the current speaker product designs do not have external charging, and some have external charging but have not done too much detection and judgment. Especially for speakers with external charging, there is no special setting, because the simple external charging consumes too much current of the speaker system, which affects the sound quality of the speaker itself. Contents of the invention [0004] The purpose of the embodiments of the present inv...
