Description

AMPLIFIER USB ADAPTER DEVICE

State of the art

Typically, loudspeakers require connecting to an AC source, transformer, and universal serial bus (USB) cable using circuits installed inside the loudspeaker, which increases the size of the loudspeaker enclosure, which reduces portability. The sophisticated installation of these cables and circuits impedes increasing power, improving sound quality and reducing cost, which impedes the widespread use of speakers.

Utility Model Essence

The main goal of this technical solution is to provide a USB speaker adapter with power amplification, which is more practical and easy to use due to the availability of many adaptation options. To achieve this, a universal serial bus (USB) is used as an interface to provide quick and easy application. Both the digital conversion integrated circuit and the power amplification integrated circuit are mounted on the adapter of the same USB port to obtain a combined device. Digital conversion and amplification schemes are not located in the loudspeaker body in order to reduce its size to improve portability, improve power amplification and achieve better sound effects.
